Chronic diseases caused by physical inactivity and inappropriate diet consumption are epidemic in modem Western society. Chronic diseases develop over a lifetime, with clinical sequelae occurring many years after the underlying pathogenesis of the disease has occurred. As we move ahead in the 21st century, cardiovascular diseases (i.e., coronary artery disease, hypertension, stroke, and heart failure), type 2 diabetes, metabolic syndrome, and cancer are the leading killers in Western society and are increasing dramatically in developing nations.

Hypertension is one of the two principal risk factors of many cardiovascular diseases, such as coronary heart disease (CHD), stroke, and CHF. Individuals are considered hypertensive if their systoHc arterial blood pressure is over 140 mm Hg (18.7 Pa) or their diastoHc arterial blood pressure is over 90 mm Hg (12 Pa). Over 60 million people, or one-third of the adult population in the United States are estimated to be hypertensive (163). About 90% of these patients are classified as primary or essential hypertensive because the etiology of their hypertension is unknown. It is generally agreed that there is a very strong genetic or hereditary component to this disease. 

They are useful against hypertension but also for cases of angina, heart failure, heart attack, arythmia, silent ischemia, stroke and senility. 

MAO has been inhibited. As a result, transmitter accumulates in the cytoplasm and is exported into the synapse via the membrane-bound transporter. The ensuing (impulse-independent) sympathetic arousal can be disastrous, culminating in a hypertensive crisis and stroke. Although this process is a pharmacological curiosity and certainly contributed to the demise of MAOIs, it is possibly overrated (Tyrer 1979) it has been estimated that the number of deaths associated with the use of the MAOI, tranylcypromine, amounts to only 1 per 14000 patient years. However, this sequence of events echoes exactly the acute actions of methylenedioxymethamphetamine (MDMA, Ecstasy ) and undoubtedly accounts for some of the deaths attributed to this drug. 

Causes of organic ED include diseases that compromise vascular flow to the corpora cavernosum (e.g., peripheral vascular disease, arteriosclerosis, essential hypertension), impair nerve conduction to the brain (e.g., spinal cord injury, stroke), and are associated with hypogonadism (e.g., prostate or testicular cancer, hypothalamic or pituitary disorders). 

Cardiovascular disease Any abnormal condition characterized by dysfunction of the heart and blood vessels. CVD includes atherosclerosis (especially coronary heart disease, which can lead to heart attacks), cerebrovascular disease (e.g., stroke), and hypertension (high blood pressure). [NIH]... 

We are living in an aging society. The United Nations estimates that the world will have two billion people over the age of 60 by 2050. With the aging population, there are old age diseases that we have to face and treat with more effective therapies. Hypertension, stroke, Alzheimer s disease, heart disease, type II diabetes, Parkinson s disease, and osteoporosis are some examples (Exhibit 11.8). 

Palladium catalyzed cross coupling of arylboronic acid to nonracemic trifluoromethylsulfonyl and fluorosulfonyl enol ethers is one of the key steps in the synthesis two endothelin receptor antagonists, SB 209670 and SB 217242, which have been clinically evaluated for several illnesses including hypertension, ischemia, stroke and others [37] (Scheme 6.14). 

As noted above, obesity is a health problem. It is associated with both elevated mortality and morbidity. More specifically, obesity is a risk factor for cardiovascular disease, including heart attack and stroke, and for high blood pressure (hypertension), diabetes, and hyperlipidemia (elevated levels of lipids in the blood, a risk factor for atherosclerosis and its sequelae), and for cancer. 

Hypertension is a common and progressive disorder which, if not effectively treated, results in an increased risk of atherosclerosis (see above), haemorrhagic stroke and damage to the kidney. For most cases of hypertension, there is no obvious cause, hence it is known as essential hypertension, so called because it was originally thonght to be essential to maintain tissue perfusion. In order to better nnderstand the regulation of blood pressure, a brief description of the regulation of contraction of smooth mnscle is provided. 

The main limitation to the clinical use of the MAOIs is due to their interaction with amine-containing foods such as cheeses, red wine, beers (including non-alcoholic beers), fermented and processed meat products, yeast products, soya and some vegetables. Some proprietary medicines such as cold cures contain phenylpropanolamine, ephedrine, etc. and will also interact with MAOIs. Such an interaction (termed the "cheese effect"), is attributed to the dramatic rise in blood pressure due to the sudden release of noradrenaline from peripheral sympathetic terminals, an event due to the displacement of noradrenaline from its mtraneuronal vesicles by the primary amine (usually tyramine). Under normal circumstances, any dietary amines would be metabolized by MAO in the wall of the gastrointestinal tract, in the liver, platelets, etc. The occurrence of hypertensive crises, and occasionally strokes, therefore limited the use of the MAOIs, despite their proven clinical efficacy, to the treatment of atypical depression and occasionally panic disorder. 

Reduction in risk of Ml, stroke, and death from cardiovascular causes - In patients 55 years of age or older at high risk of developing a major cardiovascular event because of a history of coronary artery disease, stroke, peripheral vascular disease, or diabetes that is accompanied by at least 1 other cardiovascular risk factor (eg, hypertension, elevated total cholesterol levels, low FIDL levels, cigarette smoking, documented microalbuminuria). 

Coronary heart disease is one of the leading causes of death in the industrialized world (Packer, 1992 Remme and Swedberg, 2001). Hypertension is a risk factor for cardiovascular disease and is associated with an increased incidence of stroke and coronary heart disease. Other risk factors for cardiovascular disease include also high cholesterol, diabetes, and obesity. Although there have been many advances in treatment over the past several decades, less than a quarter of all hypertensive patients have their blood pressure adequately controlled with available therapies. 

Older patients have predominantly Type 2 diabetes mellitus, which shares with Type 1 the risk for retinopathy, nephropathy and neuropathy, but carries a greater risk for macrovascular complications such as coronary artery disease, stroke and peripheral vascular disease. Many such patients have associated obesity, hypertension and hyperlipidemia, compounding the risk of cardiovascular disease. The goals of treatment of DM in the elderly are to decrease symptoms related to hyperglycaemia and to prevent long-term complications. Treatment of type 2 DM can improve prognosis. In the UKPDS trial, sulphonylureas, insulin, and metformin were all associated with a reduction in diabetes-related...
