For instance, we've seen a heart attack epidemic, an obesity epidemic, an autism epidemic, a metabolic syndrome epidemic and a hypertension epidemic. Amazingly, these epidemics have occurred despite the fact that the actual incidence of the disease in question, in most cases at least, has not changed very much. Hypertension is an established major risk factor underlying the epidemic of coronary and cardiovascular diseases in most developed countries, and it has been shown to be a public health problem in many developing countries since the 1970s. In a series of risk factors, hypertension almost competes with elevated plasma cholesterol for the first place. Communicable diseases are becoming less common in developing countries. However, the dramatic changes in lifestyle and food consumption patterns have led to the emergence of non-communicable disease, such as hypertension, as a public health problem in the Kingdom of Saudi Arabia. Several studies indicate that hypertension and its related clinical events, such as myocardial infarction and stroke, appear to be increasing, although at a lower rate than in other parts of the world. A study conducted on 13,000 Saudi subjects revealed that among the age group between 40 and 75 years, the percentage of systolic hypertensive females (15.7%) was significantly higher than males (11.0%). (Mansour M. Al-Nozha,1997) Hypertension is a chronic medical condition in which the blood pressure is elevated. It is also referred to as high blood pressure or shortened to HT, HTN or HPN. The word "hypertension", by itself, normally refers to systemic, arterial hypertension. Hypertension can be classified as either essential (primary) or secondary. Essential or primary hypertension means that no medical cause can be found to explain the raised blood pressure. It is common. About 90-95% of hypertension is essential hypertension. Secondary 2 hypertension indicates that the high blood pressure is a result of (i.e., secondary to) another condition, such as kidney disease or tumours (adrenal adenoma or pheochromocytoma). Persistent hypertension is one of the risk factors for strokes, heart attacks, heart failure and arterial aneurysm, and is a leading cause of chronic renal failure. Even moderate elevation of arterial blood pressure leads to shortened life expectancy. At severely high pressures, defined as mean arterial pressures 50% or more above average, a person can expect to live no more than a few years unless appropriately treated. Beginning at a systolic pressure (which is peak pressure in the arteries, which occurs near the end of the cardiac cycle when the ventricles are contracting) of 115 mmHg and diastolic pressure (which is minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood) of 75 mmHg (commonly written as 115/75 mmHg), cardiovascular disease (CVD) risk doubles for each increment of 20/10 mmHg. Essential hypertension Hypertension is one of the most common complex disorders. The etiology of hypertension differs widely amongst individuals within a large population. Essential hypertension is the form of hypertension that by definition, has no identifiable cause. It is the more common type and affects 90-95% of hypertensive patients, and even though there are no direct causes, there are many risk factors such as sedentary lifestyle, obesity (more than 85% of cases occur in those with a body mass index greater than 25), salt (sodium) sensitivity, alcohol intake, and vitamin D deficiency. It is also related to aging and to some inherited genetic mutations. Family history increases the risk of developing hypertension. Renin elevation is another risk factor, Renin is an enzyme secreted by the juxtaglomerular apparatus of the kidney and linked with aldosterone in a negative feedback loop. Also sympathetic overactivity is implicated. Insulin resistance which is a component of syndrome X, or the metabolic syndrome is also thought to cause hypertension. Recently low birth weight has been questioned as a risk factor for adult essential hypertension. 3 Secondary hypertension Secondary hypertension by definition results from an identifiable cause. This type is important to recognize since its treated differently than essential type by treating the underlying cause. Many secondary cause can cause hypertension, some are common and well recognized secondary causes such as Cushing's syndrome, which is a condition where both adrenal glands can overproduce the hormone cortisol. Hypertension results from the interplay of several pathophysiological mechanisms regulating plasma volume, peripheral vascular resistance and cardiac output, all of which may be increased. More than 80% of patients with Cushing's syndrome have hypertension. Another important cause is the congenital abnormality coarctation of the aorta. Adrenal A variety of adrenal cortical abnormalities can cause hypertension, In primary aldosteronism there is a clear relationship between the aldosterone-induced sodium retention and the hypertension. Another related disorder that causes hypertension is apparent mineralocorticoid excess syndrome which is an autosomal recessive disorder results from mutations in gene encoding 11β-hydroxysteroid dehydrogenase which normal patient inactivates circulating cortisol to the less-active metabolite cortisone. Cortisol at high concentrations can cross-react and activate the mineralocorticoid receptor, leading to aldosterone-like effects in the kidney, causing hypertension. This effect can also be produced by prolonged ingestion of liquorice(which can be of potent strength in liquorice candy), can result in inhibition of the 11βhydroxysteroid dehydrogenase enzyme and cause secondary apparent mineralocorticoid excess syndrome. Frequently, if liquorice is the cause of the high blood pressure, a low blood level of potassium will also be present. Yet another related disorder causing hypertension is 4 glucocorticoid remediable aldosteronism, which is an autosomal dominant disorder in which the increase in aldosterone secretion produced by ACTH is no longer transient, causing of primary hyperaldosteronism, the Gene mutated will result in an aldosterone synthase that is ACTH-sensitive, which is normally not. GRA appears to be the most common monogenic form of human hypertension. Compare these effects to those seen in Conn's disease, an adrenocortical tumor which causes excess release of aldosterone, that leads to hypertension. Another adrenal related cause is Cushing's syndrome which is a disorder caused by high levels of cortisol. Cortisol is a hormone secreted by the cortex of the adrenal glands. Cushing's syndrome can be caused by taking glucocorticoid drugs, or by tumors that produce cortisol or adrenocorticotropic hormone (ACTH). More than 80% of patients with Cushing's syndrome develop hypertension., which is accompanied by distinct symptoms of the syndrome, such as central obesity, buffalo hump, moon face, sweating, hirsutism and anxiety. Kidney Other well known causes include diseases of the kidney. This includes diseases such as polycystic kidney disease which is a cystic genetic disorder of the kidneys, PKD is characterized by the presence of multiple cysts (hence, "polycystic") in both kidneys, can also damage the liver, pancreas, and rarely, the heart and brain. It can be autosomal dominant or autosomal recessive, with the autosomal dominant form being more common and characterized by progressive cyst development and bilaterally enlarged kidneys with multiple cysts, with concurrent development of hypertension, renal insufficiency and renal pain. Or chronic glomerulonephritis which is a disease characterized by inflammation of the glomeruli, or small blood vessels in the kidneys. Hypertension can also be produced by diseases of the renal arteries supplying the kidney. This is known as renovascular hypertension; it is thought that decreased perfusion of renal tissue due to stenosis of a main or branch renal artery activates the renin-angiotensin system. also some renal tumors can cause hypertension. The differential diagnosis of a renal tumor in a young patient with hypertension includes Juxtaglomerular cell tumor, Wilms' tumor, and renal cell carcinoma, all of which may produce renin. 5 Neuroendocrine tumors are also a well known cause of secondary hypertension. Pheochromocytoma (most often located in the adrenal medulla) increases secretion of catecholamines such as epinephrine and norepinephrine, causing excessive stimulation of adrenergic receptors, which results in peripheral vasoconstriction and cardiac stimulation. This diagnosis is confirmed by demonstrating increased urinary excretion of epinephrine and norepinephrine and/or their metabolites (vanillylmandelic acid). Medication side effects Certain medications, especially NSAIDs (Motrin/Ibuprofen) and steroids can cause hypertension. High blood pressure that is associated with the sudden withdrawal of various antihypertensive medications is called Rebound Hypertension. The increases in blood pressure may result in blood pressures greater than when the medication was initiated. Depending on the severity of the increase in blood pressure, rebound hypertension may result in a hypertensive emergency. Rebound hypertension is avoided by gradually reducing the dose (also known as "dose tapering"), thereby giving the body enough time to adjust to reduction in dose. Medications commonly associated with rebound hypertension include centrally-acting antihypertensive agents, such as clonidine and beta-blockers. Pregnancy Few women of childbearing age have high blood pressure, up to 11% develop hypertension of pregnancy. While generally benign, it may herald three complications of pregnancy: pre-eclampsia, HELLP syndrome and eclampsia. Follow-up and control with medication is therefore often necessary. Sleep disturbances Another common and under-recognized cause of hypertension is sleep apnea, which is often best treated with nocturnal nasal continuous positive airway pressure (CPAP), but other approaches include the Mandibular advancement splint (MAS), UPPP, tonsillectomy, adenoidectomy, septoplasty, or weight loss. Another cause is an exceptionally rare neurological disease called Binswanger's disease, 6 causing dementia; it is a rare form of multi-infarct dementia, and is one of the neurological syndromes associated with hypertension. Pathophysiology Most of the mechanisms associated with secondary hypertension are generally fully understood. However, those associated with essential (primary) hypertension are far less understood. What is known is that cardiac output is raised early in the disease course, with total peripheral resistance (TPR) normal; over time cardiac output drops to normal levels but TPR is increased. Three theories have been proposed to explain this: Inability of the kidneys to excrete sodium, resulting in natriuretic factors such as Atrial Natriuretic Factor being secreted to promote salt excretion with the side effect of raising total peripheral resistance. An overactive Renin-angiotensin system leads to vasoconstriction and retention of sodium and water. The increase in blood volume leads to hypertension. An overactive sympathetic nervous system, leading to increased stress responses. It is also known that hypertension is highly heritable and polygenic (caused by more than one gene) and a few candidate genes have been postulated in the etiology of this condition. Diagnosis Initial assessment of the hypertensive patient should include a complete history and physical examination to confirm a diagnosis of hypertension. Most patients with hypertension have no specific symptoms referable to their blood pressure elevation. Although popularly considered a symptom of elevated arterial pressure, headache generally occurs only in patients with severe hypertension. Characteristically, a "hypertensive headache" occurs in the morning and is localized to the occipital region. Other nonspecific symptoms that may be related to elevated blood pressure include dizziness, palpitations, easy fatiguability, and impotence. 7 Prognosis It is based upon several factors including genetics, dietary habits, and overall lifestyle choices. If individuals conscious of their condition take the necessary preventive measures to lower their blood pressure, they are more likely to have a much better outcome than those who does not. Complications Hypertension is a risk factor for all clinical manifestations of atherosclerosis since it is a risk factor for atherosclerosis itself. It is an independent predisposing factor for heart failure, coronary artery disease, stroke, renal disease, and peripheral arterial disease. it is the most important risk factor for cardiovascular morbidity and mortality, in industrialized countries. The risk is increased for: Cerebrovascular accident (CVAs or strokes) Myocardial infarction (heart attack) Hypertensive cardiomyopathy (heart failure due to chronically high blood pressure) Left ventricular hypertrophy - thickening of the myocardium (muscle) of the left ventricle of the heart. Hypertensive retinopathy - damage to the retina Hypertensive nephropathy - chronic renal failure due to chronically high blood pressure "benign nephrosclerosis". Hypertensive encephalopathy - confusion, headahe, convulsion due to vasogenic edema in brain due to high blood pressure. 8 Food/Diet Therapy for Hypertension Research has shown that following a healthy eating plan can both reduce the risk of developing high blood pressure and lower an already elevated blood pressure. Vegetarian Diet Vegetarians, in general, have lower blood pressure levels and a lower incidence of hypertension and other cardiovascular diseases. Experts postulate that a typical vegetarian's diet contains more potassium, complex carbohydrates, polyunsaturated fat, fiber, calcium, magnesium, vitamin C and vitamin A, all of which may have a favorable influence on blood pressure. Fiber A high-fiber diet has been shown to be effective in preventing and treating many forms of cardiovascular disease, including hypertension. The types of dietary fiber is important. Of the greatest benefit to hypertension are the water soluble gel-forming fibers such as oat bran, apple pectin, psyllium seeds, and guar gum. These fibers, in addition to be of benefit against hypertension, are also useful to reduce cholesterol levels, promote weight loss, chelate out heavy metals, etc. Taking one to three tablespoons of herbal bulking formula containing such things as oat fiber, guar gum, apple pectin, gum karaya, psyllium seed, dandelion root powder, ginger root powder, fenugreek seed powder and fennel seed powder. Sugar Sucrose, common table sugar, elevates blood pressure. Underlying mechanism is not clearly understood. It is possible that sugar increases the production of adrenaline, which in turn, increases blood vessel constriction and sodium retention. 9 Taking a diet that is rich in high potassium foods (vegetables and fruits) and essential fatty acids. Daily intake of potassium should total 7 grams per day. The diet should be low in saturated fat, sugar and salt. In general, a whole food diet emphasizing vegetables and members of the garlic/onion family should be consumed. In an NIH sponsored research called "Dietary Approaches to Stop Hypertension (DASH)," researchers tested the effects of nutrients in food on blood pressure. The results showed that elevated blood pressures were reduced by an eating plan that emphasized fruits, vegetables, and low-fat dairy foods and was low in saturated fat, total fat, and cholesterol. The DASH diet included whole grains, poultry, fish, and nuts. It employed reduced amounts of fats, red meats, sweets, and sugared beverages. Reduce Salt and Sodium in Diet A key to healthy eating is choosing foods lower in salt and sodium. Before the widespread availability of medication to control high blood pressure, people with serious hypertension had only one treatment option, a drastically salt-reduced, low-calorie "rice diet." Some people can significantly lower their blood pressure by avoiding salt. Studies show that people in countries that use a great deal of salt in their cooking tend to have higher blood pressures than people in countries that use little salt. For example, the Japanese, whose cuisine is among the saltiest in the world, also have the highest blood pressure; and so do Americans. Americans take it for granted that blood pressure will rise as we age. But in countries with low per-capita salt intake, blood pressure does not rise significantly after puberty. For example, blacks in Africa, who typically eat a low-salt, high-fiber diet, have relatively low blood pressure, but for African-Americans, just the opposite is true. Nearly 50 percent of all African-Americans have high blood pressure, often beginning early in life. Excessive consumption of dietary sodium chloride (salt), coupled with diminished dietary potassium, induces an increase in fluid volume and an impairment of blood pressure regulating mechanisms. This results in hypertension in susceptible individuals. 10 A high potassium-low sodium diet reduces the rise in blood pressure during mental stress by reducing the blood vessel constricting effect of adrenaline. Sodium restriction alone does not improve blood pressure control; it must be accompanied by a high potassium intake. Most of us consume more salt than we need. NIH recommends limiting the sodium consumption to less than 2.4 grams (2,400 milligrams [mg] ) of sodium a day. That equals 6 grams (about 1 teaspoon) of table salt a day. The 6 grams include ALL salt and sodium consumed, including that used in cooking and at the table. Recent research has shown that people consuming diets of 1,500 mg of sodium had even better blood pressure lowering benefits. So, your doctor may advise eating less salt and sodium if you are suffering from high blood pressure. The lower-sodium diets also can keep blood pressure from rising and help blood pressure medicines work better. In a clinical study, researchers looked at the effect of a reduced dietary sodium intake on blood pressure as people followed either the DASH diet or a typical American diet. Results showed that reducing dietary sodium lowered blood pressure for both the DASH diet and the typical American diet. The biggest blood pressure-lowering benefits were for those eating the DASH diet at the lowest sodium level (1,500 milligrams per day). This study showed the importance of lowering sodium intake in your diet. The patient should watch what he/she eat. They should not add additional salt to your food. If they have high blood pressure, they should avoid eating certain highly processed, overly salted foods, such as frozen pizza, canned salted vegetables, meals from fast-food restaurants, and the like. Beneficial Vegetables and Spices for Hypertension A number of common vegetables and spices have beneficial effects in controlling hypertension. Incorporate these into your cooking. Alternately, you can make a tea or a vegetable soup. Celery (Apium graveolens). Oriental Medicine practitioners have long used celery for lowering high blood pressure. There are some experimental evidence that shows that celery is useful for this. In one animal study, laboratory animals injected with celery extract showed 11 lowered blood pressure. Eating as few as four celery stalks was found to be beneficial in lowering blood pressure in human beings. Garlic (Allium sativum). Garlic is a wonder drug for heart. It has beneficial effects in all cardiovascular system including blood pressure. In a study, when people with high blood pressure were given one clove of garlic a day for 12 weeks, their diastolic blood pressure and cholesterol levels were significantly reduced. Eating quantities as small as one clove of garlic a day was found to have beneficial effects on managing hypertension. Using garlic in cooking, salad, soup, pickles, etc. It is very versatile. Onion (Allium cepa). Onions are useful in hypertension. What is best is the onion essential oil. Two to three tablespoons of onion essential oil a day was found to lower the systolic levels by an average of 25 points and the diastolic levels by 15 points in hypertension subjects. This should not be surprising because onion is a cousin of garlic. Tomato (Lycopersicon lycopersicum). Tomatoes are high in gammaamino butyric acid (GABA), a compound that can help bring down blood pressure. Broccoli (Brassica oleracea). This vegetable contains several active ingredients that reduce blood pressure. Carrot (Daucus carota). Carrots also contain several compounds that lower blood pressure. Saffron (Crocus sativus). Saffron contains a chemical called crocetin that lowers the blood pressure. They can use saffron in cooking. (It is a very popular spice in Arabic cooking.) They can also make a tea with it. Many Indians add a pinch of saffron in the brewed tea to give a heavenly flavor. Unfortunately, it is very expensive. 12 Goal: To decrease the prevalence of HT among female pt in cardiac unit of KFSH by 20% in 2013.
