208 hospitalized patients, nearly 80 years old, were investigated because of risk factors and complicating diseases. Hypertension (58.2%), typical myocardial infarctions (37.2%) and diabetes (45.2%) were twice often as in our comparable cases without stroke. Corresponding we found signs of left ventricular hypertrophy in more than 50% post mortem. The dimensions of heart failure by hypertension are visible in ECG indicating LVH with many dysrhythmias. Early mortality (40%) as survival time are dependent on the size of the stroke. Cardiovascular causes of death were found mainly. The differences to younger patients with brain infarction seem to be only of gradually nature and especially to refer to the more intensive damaged heart.

In the course of 5 years, 9509 healthy adult subjects had an average annual incidence of 3.6 unrecognized infarcts per 1000 persons and 5.3 clinical ones per 1000 persons. A multivariate analysis showed that the most significant risk factors were age, left axis deviation, left ventricular hypertrophy, cigarette smoking, systolic or diastolic blood pressure, and peripheral vascular disease. Some of the known risk factors of clinical infarct, or angina pectoris or both, such as cholesterol, diabetes, anxiety, and psychosocial problems, do not play a significant role in unrecognized infarcts. Subjects whose electrocardiograms were initially interpreted by cardiologists as noninfarcts but by the computer as infarcts developed a high rate of unrecognized infarcts in the subsequent 5 years. A 7-year mortality follow-up showed a markedly higher rate among the unrecognized infarct group as compared with the noninfarct population, but significantly lower than those who developed a clinical infarct.

Using the age-sex-specific data collected in the Framingham Heart Study 1948--1964 together with ophthalmic diagnoses made in the Framingham Eye Study in 1973--1975, the following variables were found to be associated with senile cataract: education, casual blood sugar, systemic blood pressure, height, vital capacity, serum phospholipid and hand strength; with senile macular degeneration: systemic blood pressure, height, vital capacity, left ventricular hypertrophy, hand strength and history of lung infection; with diabetic retinopathy: casual blood sugar, urine sugar and other specific elements of diabetes; with ocular hypertension: systemic blood pressure, height, casual blood sugar and pulse rate. No variables were identified as associated with open-angle glaucoma. The paper stresses the need for corroboration of these findings, which may be a mix of real and chance associations, and the need for additional analyses before any of these associations are considered evidence of factors related to risk of ophthalmic disease.

Of 1,025 men and 1,445 women, aged 49 to 82 years, who were free of coronary heart disease (CHD), 79 men and 63 women subsequently had CHD. Using a risk function based on cholesterol in the high density and low density lipoproteins, systolic blood pressure, left ventricular hypertrophy, and diabetes, less than 2% of the subsequent CHD cases were found in the lowest decile of risk, whereas 25% of the cases for men and 37% for women were found in the highest decile. Predictability held for each specific age group. This predictability was at least as good as that obtained by the usual CHD risk profile at younger ages.

The most important factors in the prognosis of coronary artery disease are the number of arteries severly obstructed, significant involvement of the left main coronary artery, and generalized impairment of left ventricular function or ventricular aneurysm. Other prognostic influences at least partially independent of these factors are the severity of functional impairment imposed by angina pectoris, electrocardiographic evidence of left ventricular hypertrophy or conduction defects, hypertension, and diabetes. Candidates for bypass operation have a better prognosis than noncandidates, but difference in left ventricular function is responsible. Refinement of prognostic precision will depend largely on future improvement in measurement of obstructive disease and left ventricular function serially and better knowledge of the cause or causes of coronary artery disease.

We now possess enough data concerning prognosis so that we can highlight the areas of concentration for the practicing physician. A history of congestive failure, hypertension,or diabetes is of greatest importance. Smoking is in a similar category, but cholesterol elevation is not. Electrocardiographic findings can be used as an immediate discriminator, depending on whether they are normal or abnormal. Further refinements are possible, depending on whether there are ST-segment depressions or elevations, ventricular conduction defects, repetitive ventricular dysrhythmias, left ventricular hypertrophy, or Q waves of prior infarctions. The exercise electrocardiogram provides additional important information and, if markedly abnormal, can detect with reasonable degree of accuracy the presence and degree of ischemic heart disease. The coronary arteriogram, which influences many of the preceding clinical criteria, permits an accurate prediction of five-year mortality and in a preliminary fashion can be integrated with electrocardiographic and ventriculographic abnormalities to derive a significant measure of prognosis. Finally, cardiac function, if assessed according to specific criteria, becomes an extremely important variable in predicting natural history in coronary heart disease.

Mild-to-moderate essential hypertension is the most common medical problem seen by physicians in Western populations, and pharmacologic antihypertensive therapy is now usually undertaken. Clinical trials have shown that lowering of elevated blood pressure using diuretics and beta-blockers reduces cardiovascular morbidity and mortality. Despite these benefits, the trials have provided no convincing evidence that the incidence of coronary artery disease or its complications is reduced: Treated hypertensive patients remain at increased cardiovascular risk compared with untreated normotensive subjects. Possible explanations for this disappointing outcome are that the drugs used may themselves have negative effects on serum lipids, glucose, and insulin resistance, thereby outweighing their antihypertensive benefits. An equally important role in this respect may be played by the diseases and therapies most commonly found in association with mild-to-moderate hypertension: hyperlipidemia, type II diabetes, coronary artery disease, left ventricular hypertrophy, cardiac arrhythmias, peripheral arterial disease, and nephropathy. Such conditions may be potent determinants of what constitutes the optimal first-line choice of antihypertensive therapy. Furthermore, the negative effects that antihypertensive drugs can have on quality-of-life factors may result in noncompliance and ineffective long-term treatment. Therefore, in a new therapeutic approach to the treatment of high blood pressure, it would be logical to base antihypertensive therapy on strategies that not only lower the blood pressure but that have beneficial impacts on hemodynamics, vascular and cardiac structure, metabolism, and quality-of-life issues.(ABSTRACT TRUNCATED AT 250 WORDS)

The past decade has seen a shift in the strategy for hypertension treatment from stepped therapy--a highly structured monolithic series of steps--to recommendations for a more individualized selection of treatment. Severe hypertension is a clear indicator to bypass traditional steps. Demographic factors, such as age, gender, and race, are often cited, but have proved to be less helpful. Concomitant medical conditions and problems are very common and are more often the crucial determinants in the selection of antihypertensive therapy. Coronary artery disease, diabetes mellitus, heart failure, azotemia, asthma, and chronic obstructive pulmonary artery disease, anxiety, and depression are all common, and each has implications for the selection of antihypertensive therapy. Blood pressure reduction is a surrogate for reduction of cardiovascular risk, and therefore, consideration of concomitant medical problems has extended to left ventricular hypertrophy, obesity, mild hyperlipidemia, and insulin resistance, as additional risk factors in hypertension. Consideration of all these factors makes it possible to individualize antihypertensive therapy in most patients today.

Diabetes mellitus (DM)-linked metabolic alterations and hypertension concomitantly accelerate or precipitate cerebrovascular and coronary heart disease, nephropathy, retinopathy and widespread macroangiopathy, thereby conferring to diabetic patients a very high risk of morbidity, disability and early death. Therefore, the long-term care for diabetic patients should be aimed at concomitant metabolic and blood pressure (BP) control. Dietary measures are indispensable; a high fibre, low fat, low salt diet is recommended, complemented with caloric restriction and physical exercise when body weight is above the ideal. Antidiabetic pharmacotherapy involves an unresolved dilemma. The desired achievement of euglycemia necessitates effective levels of insulin, but hyperinsulinemia (due to parenteral [over]treatment in insulin-dependent DM) is suspected to promote atherogenesis and represents a coronary risk factor and perhaps even facilitates hypertension. Considering antihypertensive pharmacotherapy, thiazide-type or loop diuretics are problematic drugs in DM because they can aggravate metabolic alterations. These agents also seem to exert only a limited preventive or regressive effect on left ventricular hypertrophy (LVH); beta-blockers are also not considered ideal, since they decrease the awareness of hypoglycemia and tend to promote glucose intolerance. Unselective beta-blockers in particular promote peripheral ischemia and insulin-induced hypoglycemia, while beta-blockers without intrinsic sympathomimetic activity lower serum HDL-cholesterol. Calcium antagonists and ACE inhibitors have equivalent antihypertensive efficacy, do not impair carbohydrate and lipid homeostasis or peripheral perfusion and can effectively improve LVH. Certain ACE inhibitors may even slightly ameliorate abnormal insulin sensitivity and plasma glucose levels. While alpha-blockers share most of these desirable properties, these agents are more prone to precipitate orthostatic hypotension in the diabetic patient. The non-thiazide diuretic indapamide and the serotonin2-antagonist ketanserin also combine antihypertensive efficacy with metabolic neutrality. The ultimate goal of therapy is to improve life prognosis. In essential hypertension, conventional drug treatment based on diuretics in high dosage satisfactorily reduced cerebrovascular but not coronary complications or sudden death. In diabetic patients, the influence of antihypertensive therapy on prognosis has not been assessed prospectively. Based on retrospective analyses, Warram et al reported a 3.8 times higher mortality in diabetics treated with diuretics alone, than in diabetics with untreated hypertension (Arch Intern Med. 1991;151:1350). H. H. Parving calculated that effective BP control in patients with diabetic nephropathy might reduce 10 year-mortality from about 65 to 20 percent (J Hypertension. 1990; 8[Suppl 7]:187).(ABSTRACT TRUNCATED AT 400 WORDS)

Lowering blood pressure by medical treatment is not enough for correct prevention of the cardiovascular complications of high blood pressure. In this respect, we would like to emphasize the potential value of the non-antihypertensive effects of angiotensin-converting enzyme (ACE) inhibitors which may be summarized as follows. In the heart, ACE inhibitors significantly reduce left ventricular hypertrophy. They have no noticeable anti-ischaemic activity and are devoid of antiarrhythmic effects. On the kidneys, ACE inhibitors seem to have a protective effect, still to be determined, in certain cases of diabetes or renal impairment. ACE inhibitors have no deleterious metabolic effects. Other antihypertensive agents share the same properties. Long-term comparative trials are necessary to find out whether some of these drugs are more effective in this field than the others.
