Angiotensin-converting enzyme inhibitors (ACEIs) are effective in patients with unilateral renal artery stenosis; however, ACEIs need to be avoided in patients with bilateral renal artery stenosis or stenosis of a solitary kidney. A diuretic can be combined with an ACEI. Because of their glomerular vasodilatory effect, calcium antagonists are effective in renal artery stenosis and do not compromise renal function.

Hypertension, however, was not always considered a disease as we know it now. President Franklin D. Roosevelt was given a clean bill of health by his physician even when his BP was recorded as ~220/120. A few years later while at Yalta, Winston Churchill’s personal physician noted in his diary that President Roosevelt “appeared to be have had signs of ‘hardening of the arteries disease’ and had a few months to live.” Subsequent events demonstrated the truth of his diagnosis. President Roosevelt ultimately had a fatal hemorrhagic stroke 2 months later, and his death brought hypertension’s potential as a deadly malady to the lime light (5).

White coat hypertension is still a risk. Everyone’s blood pressure changes from time to time—it’s lower when you’re asleep, for example­­­­­—but if a child’s blood pressure continually rises when she’s anxious (such as before a test), it can be sign of high blood pressure at other times and potentially cause the same kinds of damage that standard hypertension causes.

Despite low plasma renin activity (PRA), blood pressure responds well to angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) therapy. Low doses of diuretics may also be effective. Thiazide-type diuretics may be particularly beneficial for patients aged 55 years or older with hypertension or CVD risk factors and for patients aged 60 years or older with isolated systolic hypertension. [4] The SHEP trial found that chlorthalidone stepped-care therapy for 4.5 years was associated with a longer life expectancy at 22-year follow-up in patients with isolated systolic hypertension. [96] The Syst-Eur trial used a study design and sample size similar to those of the SHEP trial, in which treatment with the CCB nitrendipine resulted in significant reduction in stroke and overall CVD events. [97]

Atherosclerosis: One of the most serious conditions that are caused by untreated hypertension, atherosclerosis is a build-up of plaque in the arteries. The plaque build-up means that there can be blocks in blood flow and when these blocks limit blood supply to the heart muscle, causing heart disease. Patients with atherosclerosis, experience chest pain when doing physical activity or stressed and they are much more likely to have a heart attack or stroke.
PH with a genetic cause is very rare and thought to be in the range of 2 to 3 in 1 million people. However, this is seemingly even rarer in children and extremely rare in infants. We are consulted to screen children from families where PH has been found in adults, and we are able to screen for the seven common PH genes. However, we are also actively researching other genetic causes for PH since these seven genes do not seem to be involved in the majority of children with PH.
Changes in blood vessel structure. Blood vessels have layers of the proteins elastin and collagen. Elastin is what makes blood vessels flexible. Collagen, which is stiffer, gives vessels structure. With age, elastin breaks down. Even the elastin that remains becomes less elastic. Meanwhile, collagen deposits in the vessels increase. As a result, blood vessels grow thicker and bend less easily over time. These changes may lead to higher systolic blood pressure.

Fifteen natural ways to lower your blood pressure High blood pressure can damage the heart. It is common, affecting one in three people in the U.S. and 1 billion people worldwide. We describe why stress, sodium, and sugar can raise blood pressure and why berries, dark chocolate, and certain supplements may help to lower it. Learn about these factors and more here. Read now
Consider initiating or intensifying pharmacologic treatment in some adults aged 60 years or older at high cardiovascular risk based on individualized assessment, to achieve a target SBP of less than 140 mm Hg to reduce the risk for stroke and cardiac events. Factors include comorbidity, medication burden, risk of adverse events, and cost. Generally, increased cardiovascular risk includes known cardiovascular disease, diabetes, or chronic kidney disease with a glomerular filtration rate of less than 45 mL/min/1.73 m 2.

Many expert groups recommend a slightly higher target of 150/90 mmHg for those over somewhere between 60 and 80 years of age.[99][100][101][105] The JNC-8 and American College of Physicians recommend the target of 150/90 mmHg for those over 60 years of age,[13][106] but some experts within these groups disagree with this recommendation.[107] Some expert groups have also recommended slightly lower targets in those with diabetes[99] or chronic kidney disease with protein loss in the urine,[108] but others recommend the same target as for the general population.[13][103] The issue of what is the best target and whether targets should differ for high risk individuals is unresolved,[109] although some experts propose more intensive blood pressure lowering than advocated in some guidelines.[110]
Hypertension is sustained elevation of resting systolic BP (≥ 130 mm Hg), diastolic BP (≥ 80 mm Hg), or both. Hypertension with no known cause (primary; formerly, essential hypertension) is most common. Hypertension with an identified cause (secondary hypertension) is usually due to sleep apnea, chronic kidney disease, or primary aldosteronism. Usually, no symptoms develop unless hypertension is severe or long-standing. Diagnosis is by sphygmomanometry. Tests may be done to determine cause, assess damage, and identify other cardiovascular risk factors. Treatment involves lifestyle changes and drugs, including diuretics, beta- blockers, ACE inhibitors, angiotensin II receptor blockers, and calcium channel blockers.

People with stage 1 hypertension who don't meet these criteria should be treated with lifestyle modifications. These include: starting the "DASH" diet, which is high in fruit, vegetables and fiber and low in saturated fat and sodium (less than 1,500 mg per day); exercising for at least 30 minutes a day, three times a week; and restricting alcohol intake to less than two drinks a day for men and one drink a day for women, said vice chairman of the new guidelines, Dr. Robert Carey, a professor of medicine and dean emeritus at the University of Virginia Health System School of Medicine.

Not Smoking While smoking is a proven risk factor for heart problems like heart attack and stroke, researchers are still trying to understand its connection to high blood pressure. Both smoking and secondhand exposure to tobacco smoke increases the risk of plaque inside the arteries, a condition known as atherosclerosis, which high blood pressure accelerates.
Aminopeptidases are involved in the metabolism of Ang II into shorter Ang peptide fragments. Aminopeptidase A (APA) converts Ang II into Ang III by removing N-terminal aspartate, which can also activate AT 1 or type 2 (AT 2) receptors. Given the ubiquitous AT 1 receptor expression, Ang II and Ang III both evoke predominant AT 1 receptor-mediated peripheral vasoconstriction and pressor responses. Interestingly, preclinical studies have shown that centrally administered Ang III more effectively raised blood pressure than did Ang II (involving centrally mediated sympathetic nerve stimulation and vasopressin release) 37, 38. Such studies provided the rationale for inhibition of APA as a potential therapeutic strategy to treat hypertension 38, 39. RB150 is a dimer of EC33, which is a selective APA inhibitor that inhibits the conversion of Ang II to Ang III 38, 39. While the clinical efficacy of RB150, also known as QGC001, in the treatment of hypertension is yet to be evaluated, it was well tolerated in healthy male volunteers and did not significantly change heart rate or blood pressure 40. However, it remains to be seen if any centrally mediated anti-hypertensive effect of QGC001, due to decreased bioavailability of Ang III in the brain, is offset by an increase in peripheral Ang II accumulation and consequent vasoconstrictor potential in hypertensive patients. It is also less common nowadays for the development of centrally acting anti-hypertensive drugs because of central side effects.

Most individuals diagnosed with hypertension will have increasing blood pressure (BP) as they age. Untreated hypertension is notorious for increasing the risk of mortality and is often described as a silent killer. Mild to moderate hypertension, if left untreated, may be associated with a risk of atherosclerotic disease in 30% of people and organ damage in 50% of people within 8-10 years after onset.

The World Health Organization has identified hypertension, or high blood pressure, as the leading cause of cardiovascular mortality.[162] The World Hypertension League (WHL), an umbrella organization of 85 national hypertension societies and leagues, recognized that more than 50% of the hypertensive population worldwide are unaware of their condition.[162] To address this problem, the WHL initiated a global awareness campaign on hypertension in 2005 and dedicated May 17 of each year as World Hypertension Day (WHD). Over the past three years, more national societies have been engaging in WHD and have been innovative in their activities to get the message to the public. In 2007, there was record participation from 47 member countries of the WHL. During the week of WHD, all these countries – in partnership with their local governments, professional societies, nongovernmental organizations and private industries – promoted hypertension awareness among the public through several media and public rallies. Using mass media such as Internet and television, the message reached more than 250 million people. As the momentum picks up year after year, the WHL is confident that almost all the estimated 1.5 billion people affected by elevated blood pressure can be reached.[163]
Modern understanding of the cardiovascular system began with the work of physician William Harvey (1578–1657), who described the circulation of blood in his book "De motu cordis". The English clergyman Stephen Hales made the first published measurement of blood pressure in 1733.[152][153] However, hypertension as a clinical entity came into its own with the invention of the cuff-based sphygmomanometer by Scipione Riva-Rocci in 1896.[154] This allowed easy measurement of systolic pressure in the clinic. In 1905, Nikolai Korotkoff improved the technique by describing the Korotkoff sounds that are heard when the artery is ausculated with a stethoscope while the sphygmomanometer cuff is deflated.[153] This permitted systolic and diastolic pressure to be measured.

The most common symptoms of pulmonary hypertension include shortness of breath (dyspnea), fatigue, dizziness or fainting spells (syncope), pressure or pain in the chest, swelling (edema) in the ankles, legs or abdomen (ascites), bluish color of the lips and skin (cyanosis) and irregular heart beat. The disease is difficult to diagnose because its symptoms are easily mistaken by other lung or heart disease, but also because its causes are not fully disclosed and are different depending on the subtype of disease.
An electrocardiogram is known by the acronyms "ECG" or "EKG" more commonly used for this non-invasive procedure to record the electrical activity of the heart. An EKG generally is performed as part of a routine physical exam, part of a cardiac exercise stress test, or part of the evaluation of symptoms. Symptoms evaluated include palpitations, fainting, shortness of breath, dizziness, fainting, or chest pain.
Secondary hypertension results from an identifiable cause. Kidney disease is the most common secondary cause of hypertension.[23] Hypertension can also be caused by endocrine conditions, such as Cushing's syndrome, hyperthyroidism, hypothyroidism, acromegaly, Conn's syndrome or hyperaldosteronism, renal artery stenosis (from atherosclerosis or fibromuscular dysplasia), hyperparathyroidism, and pheochromocytoma.[23][47] Other causes of secondary hypertension include obesity, sleep apnea, pregnancy, coarctation of the aorta, excessive eating of liquorice, excessive drinking of alcohol, and certain prescription medicines, herbal remedies, and illegal drugs such as cocaine and methamphetamine.[23][48] Arsenic exposure through drinking water has been shown to correlate with elevated blood pressure.[49][50]
The goal of therapy in uncomplicated hypertension is to reduce cardiovascular risk by lowering the patient's blood pressure. If non-drug treatment is ineffective, the choice of drug treatment is determined by its safety and efficacy. When safety and efficacy are equal the lowest cost drug should be prescribed. For most patients the first choice drug is a low-dose thiazide diuretic.
In a subgroup analysis from the TRINITY study (TRI ple therapy with olmesartan medoxomil, amlodipine, and hydrochlorothiazide in hyperteN sive patienT s studY), Chrysant et al reported that in patients with hypertension and diabetes, triple-combination drug therapy resulted in greater BP reductions and BP-goal achievement (< 130/80 mm Hg) than dual-combination drug therapy. The triple-combination regimen consisted of olmesartan medoxomil, 40 mg; amlodipine besilate, 10 mg; and hydrochlorothiazide, 25 mg.
MRI (or magnetic resonance imaging) scan is a radiology technique which uses magnetism, radio waves, and a computer to produce images of body structures. MRI scanning is painless and does not involve X-ray radiation. Patients with heart pacemakers, metal implants, or metal chips or clips in or around the eyes cannot be scanned with MRI because of the effect of the magnet.
In hypertensive emergency, there is evidence of direct damage to one or more organs.[27][28] The most affected organs include the brain, kidney, heart and lungs, producing symptoms which may include confusion, drowsiness, chest pain and breathlessness.[26] In hypertensive emergency, the blood pressure must be reduced more rapidly to stop ongoing organ damage,[26] however, there is a lack of randomized controlled trial evidence for this approach.[28]

Hypertension, commonly known as high blood pressure, affects millions of Americans, from children to older adults. High blood pressure can be caused by many factors, but mostly notably are diabetes, obesity, and excessive alcohol consumption. High blood pressure happens when the pressure your blood exerts against the artery walls is too high, leading to life-threatening conditions, such as heart disease and stroke. Despite these severe health consequences, the vast majority of individuals have no symptoms. This is why hypertension is sometimes called a “silent” killer. Learn more about these potential symptoms and what that means for your health below.

Emergency department visits for hypertension with complications and secondary hypertension also rose, from 71.2 per 100,000 population in 2006 to 84.7 per 100,000 population in 2011, while again, admission rates fell, dropping from 77.79% in 2006 to 68.75% in 2011. The in-hospital mortality rate for admitted patients dropped as well, from 1.95% in 2006 to 1.25% in 2011. [37]

Hypertension, especially stage 2 hypertension, can affect the retina, choroid, and optic nerve, as well as increase intraocular pressure (IOP). [2] In hypertensive retinopathy, the most common finding is generalized or focal narrowing of the retinal arterioles; occlusion or leakage of the retinal vessels may occur with acute or advanced hypertension. Hypertensive choroidopathy most commonly manifests in young patients with acute elevated blood pressure (BP), such as that which occurs in eclampsia or pheochromocytoma. [2]
The success of pharmacological treatment of a common human malady like hypertension that affects more than a billion of our fellow human beings is a mega achievement. In the history of modern medicine, only vaccination to prevent infectious diseases, antibiotics for infections, and oral hydration for diarrheal diseases have had similar success and impact on global health.

Hypertension, also called high blood pressure, condition that arises when the blood pressure is abnormally high. Hypertension occurs when the body’s smaller blood vessels (the arterioles) narrow, causing the blood to exert excessive pressure against the vessel walls and forcing the heart to work harder to maintain the pressure. Although the heart and blood vessels can tolerate increased blood pressure for months and even years, eventually the heart may enlarge (a condition called hypertrophy) and be weakened to the point of failure. Injury to blood vessels in the kidneys, brain, and eyes also may occur.

Historically the treatment for what was called the "hard pulse disease" consisted in reducing the quantity of blood by bloodletting or the application of leeches.[152] This was advocated by The Yellow Emperor of China, Cornelius Celsus, Galen, and Hippocrates.[152] The therapeutic approach for the treatment of hard pulse disease included changes in lifestyle (staying away from anger and sexual intercourse) and dietary program for patients (avoiding the consumption of wine, meat, and pastries, reducing the volume of food in a meal, maintaining a low-energy diet and the dietary usage of spinach and vinegar).

The history of hypertension goes back a long way (1). In ancient Chinese and Indian Ayurvedic medicine, the quality of an individual’s pulse, as felt by gentle palpation by the trained physician, was a window into the condition of the cardiovascular system. What was called “hard pulse” possibly would qualify for the modern term of hypertension. Any article on the history of hypertension, however, is incomplete without a mention of Akbar Mahomed’s contribution in developing the modern concept of hypertension. In the late nineteenth century, Frederick Akbar Mahomed (1849–1884), an Irish-Indian physician working at Guy’s hospital in London, first described conditions that later came to be known as “essential hypertension,” separating it from the similar vascular changes seen in chronic glomerulonephritis such as Bright’s disease. Some of the noteworthy contributions of Akbar Mahomed were the demonstration that high BP could exist in apparently healthy individuals, that high BP was more likely in older populations, and that the heart, kidneys, and brain could be affected by high arterial tension (Interested readers may read about Akbar’s life in a detailed account written by Cameron in Kidney international) (2, 3). However, only with the advent of the mercury sphygmomanometer in the early twentieth century and defining of the systolic and diastolic BP by appearance/disappearance of Korotkoff sounds as heard via the stethoscope, the modern quantitative concept of hypertension – broken into systolic and diastolic categories – came into existence. By the middle of the twentieth century, checking BP by sphygmomanometer became part of the routine physical examination in hospitals and clinics (4).
Urine albumin-to-creatinine ratio. A health care provider uses the albumin and creatinine measurement to determine the ratio between the albumin and creatinine in the urine. Creatinine is a waste product in the blood that is filtered in the kidneys and excreted in the urine. A urine albumin-to-creatinine ratio above 30 mg/g may be a sign of kidney disease.
Management of mild gestational hypertension or preeclampsia without severe features may take place either in a hospital or on an outpatient basis (you can stay at home with close monitoring by your health care professional). You may be asked to keep track of your baby’s movements by doing a daily kick count and to measure your blood pressure at home. You will need to see your health care professional at least weekly and sometimes twice weekly. Once you reach 37 weeks of pregnancy, it may be recommended that you have your baby. If test results show that the baby is not doing well, you may need to have the baby earlier.
Hypertension, however, was not always considered a disease as we know it now. President Franklin D. Roosevelt was given a clean bill of health by his physician even when his BP was recorded as ~220/120.

The prevalence of primary hyperaldosteronism increases with the severity of hypertension, being 2% in stage 1 and 20% in resistant hypertension. [110] Hypokalemia (an unprovoked or an exaggerated hypokalemic response to a thiazide) and metabolic alkalosis are important clues to the presence of primary hyperaldosteronism. However, these are relatively late manifestations; in a large subset of patients, the serum potassium concentration and bicarbonate are within the reference range, and additional screening testing is needed in patients with high index of suspicion for primary hyperaldosteronism.

Blood pressure is the measurement of the pressure or force of blood pushing against blood vessel walls. In hypertension (high blood pressure), the pressure against the blood vessel walls is consistently too high. High blood pressure is often called the “silent killer” because you may not be aware that anything is wrong, but the damage is occurring within your body.
VA-co-op study phase 1 followed by 2 established for the first time that diastolic HTN > 90 to 129 was treatable with available drugs and reduced stroke, CHF, and mortality. HDFP study affirmed that BP treatment target to diastolic goal of 90 gave much better CV outcome results than usual BP treatment. MRC and EWHPE confirmed this for younger and older patients, respectively, in non-US population. MRFIT study showed that of three risk factors for CHD (hyperlipidemia, smoking, and hypertension) only hypertension was effectively treatable by drugs available that time. SHEP study broadened the definition of treatable hypertension to include isolated systolic hypertension, treatment of which in elderly gave profound CV and mortality benefits. DASH study convincingly showed the benefits of Mediterranean type diet in lowering BP and that salt restriction adds to that benefit. HOT study established that lowering diastolic BP goal <90 (85 or 80) does not add any further benefits. TOMHS and MRC 2 were relatively minor studies. UKPDS Hypertension studies showed that moderately tight BP control <150/85 goal-reduced diabetic mortality by 32% – much higher level of benefits than in non-diabetics. AASK study was done in African-Americans with CKD and showed that tight BP control over usual BP control did not affect CKD progression but use of ACEI caused superior reno-protection over CCB. ALLHAT study showed that use of thiazide drugs (Chlorthalidone) did not increase incidence of MI or mortality over other classes of drugs (CCB, ACEI, or AB). It also showed incidence of CHF was more with use of AB, CCB, and ACEI than CTDN. ASCOT study showed superiority of combination of ACEI and CCB over BB and thiazide (HCTZ) in preventing CV outcomes. CAFE, a sub study of ASCOT showed that BB failed to lower central aortic BP as opposed to peripheral BP. HYVET showed that treatment of hypertension in very elderly (>80) is even more beneficial than in any other age group. ACCOMPLISH study showed superiority of combination of ACEI and CCB over ACE and thiazide (HCTZ and not CTDN) for CV outcomes. ACCORD study showed that in diabetics, lowering BP target to 120 sys over conventional 140 added no further reduction in CV or renal outcomes. SPRINT study showed significant mortality and cardiovascular benefits in group with Systolic BP treatment goal of 120 compared to goal of 140 in non-diabetic patients.
Moreover, it is estimated that 1 death is prevented per 11 patients treated for stage 1 hypertension and other cardiovascular risk factors when a sustained reduction of 12 mm Hg in systolic BP over 10 years is achieved. [2] However, for the same reduction is systolic BP reduction, it is estimated that 1 death is prevented per 9 patients treated when cardiovascular disease or end-organ damage is present. [2]
Surgical resection is the treatment of choice for pheochromocytoma, because hypertension is cured by tumor resection. In the preoperative phase, nonspecific alpha-adrenergic blockade is indicated with phenoxybenzamine, and following adequate alpha-adrenergic blockade, beta-adrenergic blockade is added if excess tachycardia is present. These patients are often volume contracted and require saline or sodium tablets. Catecholamine production can be reduced further by metyrosine.

In addition to the ACE/AT 1 receptor arm of the RAS, there are two separate but related “protective” arms of the RAS, so called because their activation generally opposes AT 1 receptor-mediated cardiovascular effects. These include the Ang III/AT 2 receptor arm 41, 42 and the ACE2/Ang (1–7)/Mas receptor arm 41, 43– 45. Within the RAS, there are a number of bioactive Ang peptides in addition to the main effector Ang II. For example, Ang III can also exert more subtle depressor effects and natriuretic responses in preclinical studies that are mediated by AT 2 receptor stimulation 41, 42. A number of selective AT 2 receptor agonists have been developed 45, of which compound 21 (C21) has been the best studied in preclinical hypertension-related models. Indeed, selective AT 2 receptor stimulation reduces hypertension-induced target organ damage, even in the absence of blood pressure reduction in most but not all instances 42, 46. The AT 2 receptor field has been hampered by a lack of selective ligands, but there is great interest in the clinical effects of AT 2 receptor activation and the potential for additive effects of AT 2 receptor agonists with conventional RAS blockade. However, C21 has only entered phase I testing in healthy volunteers at this stage, so this field will be watched with interest.

How do these recommendations match those of expert bodies in Australia and overseas? They are consistent with the recommendations of Therapeutic Guidelines: Cardiovascular, 2003 and go further than those of the National Heart Foundation, 2004 which provide no specific recommendation as to first-line choice. The 2003 World Health Organization (WHO)/International Society of Hypertension statement on management of hypertension advises: 'for the majority of patients without a compelling indication for another class of drug, a low dose of a diuretic should be considered as the first choice of therapy on the basis of the comparative trial data, availability, and cost.'9 Other guideline groups, such as the National Institute for Clinical Excellence in the UK, have adopted a similar position to that of WHO, again based on an independent, comprehensive review of the clinical evidence.10


Neprilysin (neutral endopeptidase 24.11) is an enzyme responsible for the breakdown of natriuretic peptides and has long been considered a target for hypertension. Indeed, inhibition of neprilysin increases natriuretic peptide levels, resulting in natriuresis, vasodilation, and functional inhibition of the RAS. However, any blood-pressure-lowering effect of neprilysin inhibition is offset, since this enzyme also degrades peptides such as endothelin-1 and Ang II that cause vasoconstriction. Indeed, combined neprilysin and ACE inhibition, achieved using omapatrilat, evoked greater anti-hypertensive effects than did the ACE inhibitor enalapril alone 21. However, the higher rate of angioedema noted by omapatrilat (most likely involving raised bradykinin levels) in large-scale heart failure trials has led to the discontinuation of this therapeutic strategy, despite clinical efficacy 22. Given that AT 1 receptor antagonists, unlike ACE inhibitors, do not inhibit bradykinin metabolism, other combinations of RAS and neprilysin inhibition have been considered. Indeed, there is much interest in a new combination of equal proportions of the AT 1 receptor antagonist valsartan and a neprilysin inhibitor sacubitril, known as LCZ696.
Blood pressure is considered to be elevated at hypertensive levels when systolic blood pressure (SBP) is ≥140 mmHg and/or diastolic blood pressure is ≥90 mmHg. Hypertension is generally considered to be one of the strongest modifiable risk factors for cardiovascular disease. Its asymptomatic clinical presentation means that there is a long exposure time that contributes to cardiovascular complications and ultimately leads to a detrimental impact on global health.
In the presence of hypertensive optic neuropathy, a rapid reduction of BP may pose a risk of worsening ischemic damage to the optic nerve. The optic nerve demonstrates autoregulation, so there is an adjustment in perfusion based on BP. A precipitous reduction in BP will reduce perfusion to the optic nerve and central nervous system as a result of their autoregulatory changes, resulting in infarction of the optic nerve head and, potentially, acute ischemic neurologic lesions of the CNS.
Medical therapy is indicated in patients with adrenal hyperplasia, patients with adenoma who are poor surgical risks, and patients with bilateral adenomas. These patients are best treated with sustained salt and water depletion. Hydrochlorothiazide or furosemide in combination with either spironolactone or amiloride corrects hypokalemia and normalizes the blood pressure. Some patients may require the addition of a vasodilator or a beta-blocker for better control of hypertension.
Everything you need to know about hypertension Hypertension or high blood pressure can lead to heart disease, stroke, and death and is a major global health concern. A range of risk factors may increase the chances of a person developing hypertension, but can it be prevented? Read on to find out what causes hypertension, its symptoms, types, and how to prevent it. Read now

The first line of treatment for hypertension is lifestyle changes, including dietary changes, physical exercise, and weight loss. Though these have all been recommended in scientific advisories,[111] a Cochrane systematic review found no evidence for effects of weight loss diets on death, long-term complications or adverse events in persons with hypertension.[112] The review did find a decrease in blood pressure.[112] Their potential effectiveness is similar to and at times exceeds a single medication.[12] If hypertension is high enough to justify immediate use of medications, lifestyle changes are still recommended in conjunction with medication.

First randomized controlled trial to show benefits of ­treating isolated systolic hypertension which prior to this most ­remarkable study was considered benign or not amenable to treatment, though isolated systolic hypertension showed more associations with CV morbidities and ­mortalities per Framingham and other studies. The success of this study opened up the ­treatment option to 50 million people in US alone.
Recognizing heart attack symptoms and signs can help save your life or that of someone you love. Some heart attack symptoms, including left arm pain and chest pain, are well known but other, more nonspecific symptoms may be associated with a heart attack. Nausea, vomiting, malaise, indigestion, sweating, shortness of breath, and fatigue may signal a heart attack. Heart attack symptoms and signs in women may differ from those in men.
We know many isolated small communities like Kuna Indians, who continue to follow their ancestral traditions, do not develop hypertension even in their very old age. It is possibly not gene-related, since they develop hypertension when they immigrate to western communities (44, 45). Thus, we have to continue to strive to expand our knowledge of the physiology and epidemiology of hypertension and related diseases. We must explore other potential non-drug therapies. Renal sympathetic nerve ablation showed some initial promise but needs lots of work to determine its role (46). Similarly, the role of different lifestyle improvements including optimal salt and fruits/vegetable intake, role of flavonoids from cocoa, coffee, or tea needs further exploration and refinement.
Before measuring your blood pressure, do not smoke, drink caffeinated beverages, or exercise for at least 30 minutes before the test. Rest for at least five minutes before the measurements and sit still with your back straight and supported. Feet should be flat on the floor and not crossed. Your arm should also be supported on a flat surface like a table with the upper arm at heart level.
What is a normal blood pressure? Blood pressure is essential to life because it forces the blood around the body, delivering all the nutrients it needs. Here, we explain how to take your blood pressure, what the readings mean, and what counts as low, high, and normal. The article also offers some tips on how to maintain healthy blood pressure.
