The prevalence of abnormalities of lipoprotein cholesterol and apolipoproteins A-I and B and lipoprotein (a) [Lp(a)] was determined in 321 men (mean age 50 +/- 7 years) with angiographically documented coronary artery disease and compared with that in 901 control subjects from the Framingham Offspring Study (mean age 49 +/- 6 years) who were clinically free of coronary artery disease. After correction for sampling in hospital, beta-adrenergic medication use and effects of diet, patients had significantly higher cholesterol levels (224 +/- 53 vs. 214 +/- 36 mg/dl), triglycerides (189 +/- 95 vs. 141 +/- 104 mg/dl), low density lipoprotein (LDL) cholesterol (156 +/- 51 vs. 138 +/- 33 mg/dl), apolipoprotein B (131 +/- 37 vs. 108 +/- 33 mg/dl) and Lp(a) levels (19.9 +/- 19 vs. 14.9 +/- 17.5 mg/dl). They also had significantly lower high density lipoprotein (HDL) cholesterol (36 +/- 11 vs. 45 +/- 12 mg/dl) and apolipoprotein A-I levels (114 +/- 26 vs. 136 +/- 32 mg/dl) (all p less than 0.005). On the basis of Lipid Research Clinic 90th percentile values for triglycerides and LDL cholesterol and 10th percentile values for HDL cholesterol, the most frequent dyslipidemias were low HDL cholesterol alone (19.3% vs. 4.4%), elevated LDL cholesterol (12.1% vs. 9%), hypertriglyceridemia with low HDL cholesterol (9.7% vs. 4.2%), hypertriglyceridemia and elevated LDL cholesterol with low HDL cholesterol (3.4% vs. 0.2%) and Lp(a) excess (15.8% vs. 10%) in patients versus control subjects, respectively (p less than 0.05). Stepwise discriminant analysis indicates that smoking, hypertension, decreased apolipoprotein A-I, increased apolipoprotein B, increased Lp(a) and diabetes are all significant (p less than 0.05) factors in descending order of importance in distinguishing patients with coronary artery disease from normal control subjects. Not applying a correction for beta-adrenergic blocking agents, sampling bias and diet effects leads to a serious underestimation of the prevalence of LDL abnormalities and an overestimation of HDL abnormalities in patients with coronary artery disease. However, 35% of patients had a total cholesterol level less than 200 mg/dl after correction; of those patients, 73% had an HDL cholesterol level less than 35 mg/dl.

Studies have proven beyond doubt that certain behaviors (smoking, inactivity) and conditions (hypertension, diabetes, obesity, hyperlipidemia) increase the risk of coronary artery disease. In many cases, the risk can be reduced dramatically with nonpharmacologic methods, but if needed, effective medications are available. First, however, patients at risk must be identified and educated about the importance of adopting a healthy life-style. The authors address all of these issues.

Various risk factors, such as smoking and diabetes, have an adverse effect on women's inherent biological protection from coronary artery disease (CAD). In women, CAD is most likely to present as angina. Although infarction as the initial event is less common in women than in men, it is more likely to be fatal. The prognosis for women with diabetes and CAD is especially poor. Differences in the therapeutic approach to CAD in men and women do not appear justified. Preventive strategies for women center around cessation of smoking, aspirin therapy, diet modification, and estrogen therapy.

The predictors of premature coronary atherosclerosis were examined in 203 patients (99 men aged less than or equal to 50 years, and 104 women aged less than or equal to 60 years) undergoing elective diagnostic coronary arteriography. Age, cigarette smoking, hypertension, obesity, diabetes, positive family history of premature coronary artery disease (CAD), and plasma levels of total cholesterol, triglyceride, lipoproteins (i.e., very low, intermediate-, low-, and high-density [HDL] lipoproteins and their subfractions [HDL2 and HDL3], and lipoprotein [a]) and apolipoproteins (apoA-1, apoA-2 and apoB, respectively) were examined using univariate analyses and multivariate logistic regression. In men, age (p less than 0.05), smoking (p less than 0.05), and plasma triglyceride (p less than 0.02) and apoA-1 (p less than 0.05) levels were independently associated with CAD. In women, smoking (p less than 0.001) and plasma apoB levels (p less than 0.04) were the strongest variables independently associated with CAD. It is concluded that the "nontraditional" risk factors (plasma apoA-1 and apoB levels) are better predictors of premature CAD than are plasma lipoproteins and that smoking is the strongest of the traditional nonlipid risk factors.

To evaluate the prognostic importance of coronary artery disease among patients undergoing carotid endarterectomy, 177 residents of Olmsted County, Minnesota who underwent carotid endarterectomy during the period 1970 through 1988 were followed up to July 1, 1989. Patients were stratified as to the presence (n = 64) or absence (n = 93) of overt coronary artery disease or prior myocardial revascularization (n = 20) at the time of endarterectomy. At 30 days after carotid endarterectomy, there were no significant differences between patients with or without coronary artery disease in the occurrence of death, myocardial infarction or stroke. Kaplan-Meier estimate of 8-year relative survival after carotid endarterectomy (assessed as a percent of survival in age- carotid endarterectomy (assessed as a percent of survival in age- and gender-matched control subjects) was 89% in those without and 75% in those with overt coronary artery disease. Of the 59 total deaths, 29 (49%) had a cardiac cause and 4 (7%) were due to stroke (p less than 0.0001). The cumulative incidence of a cardiac event at 8 years after carotid endarterectomy was greater in those with than in those without overt coronary artery disease (61% vs. 25%, p less than 0.0001). In multivariable analysis, uncorrected coronary artery disease and diabetes were the only independent predictors of subsequent cardiac events, whereas age was the only independent predictor of death. These population-based data suggest that carotid endarterectomy can be safely undertaken in patients with stable coronary artery disease. In long-term follow-up of these patients, coronary rather than cerebral vascular disease is the most frequent cause of morbidity and mortality. Thus, these data lend strong support to the concept of early identification and management of coronary artery disease in patients undergoing carotid endarterectomy.

Individuals with spinal cord injury (SCI) currently have a longer life span as a result of recent improvements in medical care. As in the able-bodied population, cardiovascular disease is the leading cause of death in persons with SCI, but it appears to occur at younger ages in those with SCI than in the able-bodied population. The reduction in level of activity and adverse changes in body composition caused by SCI have profound metabolic consequences that may influence the progression and severity of coronary artery disease. Metabolic sequelae of SCI include disorders of carbohydrate and lipid metabolism. Almost half of the 45 active, healthy subjects with paraplegia we studied have a disorder of carbohydrate tolerance, 1 in 5 subjects having a diabetic oral glucose tolerance test. Hyperinsulinemia is found in those with abnormal glucose tolerance. Subjects with paraplegia having impaired glucose tolerance or diabetes mellitus are significantly older than those with normal glucose tolerance. High-density lipoprotein cholesterol is markedly depressed, and low density lipoprotein is relatively elevated. Radionuclide myocardial perfusion imaging after upper body ergometry exercise reveals latent coronary artery disease in 12 of 19 subjects with paraplegia.

In developing countries diabetes in the elderly is thought to be uncommon and is consequently ignored by health planners. We assessed the prevalence of complications of diabetes mellitus and frequency of hospital admissions in patients aged 60 and over in a hospital diabetic clinic in Sri Lanka. Elderly diabetic patients, though comprising only 23% of clinic patients, accounted for 46% of admissions. The prevalence of coronary artery disease, peripheral vascular disease, cerebrovascular disease, hypertension and visual handicap was increased in the diabetic patients when compared to age and gender matched controls. We conclude that diabetes in the elderly is a significant cause of morbidity in Sri Lanka.

Despite a marked reduction in cardiovascular morbidity and mortality, treated hypertensive patients remain at increased risk of coronary artery disease and its complications compared with untreated normotensive subjects. Mild hypertension is often associated with other, usually chronic, diseases. The failure of first-line antihypertensive therapy to deal adequately with concomitant disease and associated therapy might account for the poor improvement in the cardiovascular prognosis. This possibility has been addressed in an ongoing trial of novel design, the Perindopril Therapeutic Safety Study, a multicenter, double-blind, randomized and placebo-controlled trial to determine the safety, efficacy, and interaction of angiotensin-converting enzyme (ACE) inhibition with eight of the most common concomitant diseases and their therapies. A total of 480 male and female patients (60 per disease group) aged 30-70 years, with a diastolic pressure of 90-104 mm Hg, were included after a 3-week placebo run-in if they satisfied standard criteria for any of the following: hyperlipidemia, type II diabetes, ischemic heart disease, cardiac arrhythmia, peripheral arterial disease, nephropathy with proteinuria, chronic obstructive lung disease, or rheumatoid arthritis. Of these, 460 patients have completed the 6-week double-blind phase (comprising two assessments, at 3 and 6 weeks), and are currently undergoing assessments every 3 months over a 1-year follow-up period. The end points include the incidence of progression or improvement in concomitant disease, the incidence of positive or negative interaction between ACE inhibition and concomitant therapy, change in blood pressure, adverse biochemical and hemodynamic reactions, self-reported side effects, and quality of life indices. Interim results for the 6-week double blind phase will shortly be available. However, the desirability and feasibility of conducting a study according to this novel design have already been proved.

The authors conducted a case-control study of risk factors for retinal vein occlusions using 87 patients with vein occlusions, chosen randomly from photographic files from their institution between 1985 and 1990, and a control group of 85 subjects 38 years of age (the youngest individual in the vein occlusion group) or older, who were randomly selected from the records of two general ophthalmologists in the authors' department. Certain risk factors for retinal vein occlusion were highly significant when subjects with retinal vein occlusion were compared with the control group. These risk factors included systemic hypertension (odds ratio [OR], 3.86; 95% confidence interval [Cl], 2.08 to 7.16), open-angle glaucoma (OR, 2.89; 95% Cl, 1.38 to 6.05), and male sex (OR, 2.61; 95% Cl, 1.43 to 4.79). Race, presence of diabetes mellitus, history of coronary artery disease or stroke, and family history of diabetes, glaucoma, coronary artery disease, or stroke were not significant risk factors in the population studied. Logistic analysis of the risk factors showed no interactions. Risk factors for branch retinal vein occlusion and central retinal vein occlusion were identical.

The prognostic value of intravenous dipyridamole myocardial perfusion imaging has not been studied in a large series of elderly patients. Patients greater than or equal to 70 years of age with known or suspected coronary artery disease were evaluated to determine the predictive value of intravenous dipyridamole thallium-201 imaging for subsequent cardiac death or nonfatal myocardial infarction. Of the 348 patients, 207 were symptomatic and 141 were asymptomatic; 52% of the asymptomatic group had documented coronary artery disease. During 23 +/- 15 months of follow-up, there were 52 cardiac deaths, 24 nonfatal myocardial infarctions and 42 revascularization procedures (percutaneous transluminal coronary angioplasty in 20; coronary artery bypass surgery in 22). Clinical univariate predictors of a cardiac event included previous myocardial infarction, congestive heart failure symptoms, hypercholesterolemia and diabetes (all p less than 0.05). The presence of a fixed, reversible or combined thallium-201 defect was significantly associated with the occurrence of cardiac death or myocardial infarction during follow-up (p less than 0.05). Cardiac death or nonfatal myocardial infarction occurred in only 7 (5%) of 150 patients with a normal dipyridamole thallium-201 study (p less than 0.001). Stepwise logistic regression analysis of clinical and radionuclide variables revealed that an abnormal (reversible or fixed) dipyridamole thallium-201 study was the single best predictor of cardiac events (relative risk 7.2, p less than 0.001). As has been demonstrated in younger patients, previous myocardial infarction (relative risk 1.8, p less than 0.001) and symptoms of congestive heart failure at presentation (relative risk 1.6, p = 0.02) were also significant independent clinical predictors of cardiac death or myocardial infarction.(ABSTRACT TRUNCATED AT 250 WORDS)
