Few data are available regarding the outcome of women in cardiac rehabilitation. To determine whether women differ from men in clinical profile and outcome, 225 consecutive patients were prospectively evaluated in an urban, multidisciplinary, exercise-based cardiac rehabilitation program. Among the 51 women (age 56 +/- 10) and 174 men (age 54 +/- 10), most were: white (84%), married (64%), employed (63%), had had myocardial infarction or revascularization, or both (66%), and traveled less than 10 miles to the program (92%). Risk profiles revealed obesity in 48% (mean Metropolitan Relative Weight = 124 +/- 22%), hypertension in 47%, smoking in 23%, diabetes in 16%, and mean cholesterol of 236 +/- 45 mg/dl. Compared with men, more women were nonwhite, unemployed, unmarried, hypertensive or diabetic (p less than 0.0001) and had higher cholesterol (p less than 0.01). Compliance rates were similar for women (51%) and men (63%) (p = not significant). Univariate predictors of program noncompliance differed between women and men. Initial exercise capacity was less for women than for men, but both groups achieved a similar training effect. Women increased their exercise time by 31% and peak METs by 30%, whereas men showed a 21% increase in exercise time and 16% increase in peak METs achieved (p less than 0.001). Thus, in this cardiac rehabilitation program, women have a less favorable risk factor profile and differ from men with regard to baseline demographics and predictors of program completion. Women, however, have similar rates of compliance and achieve the same improvement in functional capacity with training.

To evaluate the spectrum of coronary artery disease (CAD) in cocaine users, coronary angiograms obtained from 33 patients (26 men [79%] and 7 women [21%], mean age 37 years) with history of cocaine use and cardiac symptoms were retrospectively reviewed. Clinical indications for coronary angiograms included chest pain (n = 28), congestive failure (n = 4) and complete heart block (n = 1). Coronary angiograms were reviewed independently by 2 angiographers unaware of patient's clinical status. Thirteen patients (40%) had normal coronary angiograms, and 20 (60%) had CAD; 7 (21%) had mild CAD (less than or equal to 70% diameter stenosis), and 13 (40%) had significant CAD (greater than 70% diameter stenosis). Of 13 patients with significant CAD, 7 had 1-vessel, 4 had 2-vessel and 2 had 3-vessel CAD. There was enzymatic evidence of myocardial infarction in 12 of 33 patients (36%); all 12 had CAD (10 with significant and 2 with mild CAD). Mean age and number of risk factors (serum total cholesterol, cigarette smoking, systemic hypertension, diabetes mellitus, family history of CAD, and obesity) in patients with CAD (mild or significant) and with normal coronary angiograms were not statistically different. Left ventricular ejection fraction was normal in 15 patients (45%) and depressed in 18 (55%). All patients with CAD and low ejection fractions (n = 12) had regional wall motion abnormalities, whereas all those with normal coronary arteries and low ejection fraction (n = 6) had global hypokinesia.

The aim of the study was to examine the relationships of obesity, lipids and apolipoproteins with the risk for subsequent ischaemic heart disease in middle-aged women, using a case-control study nested within a cohort study. A total of 3634 women aged 26-88 were recruited in Guernsey between 1977 and 1985 and followed until June 1986 by abstraction of their general practitioners' records. Fifty-one cases of incident ischaemic heart disease (11 myocardial infarction, 40 angina) were identified. For each case up to 4 controls were selected, matched for age and date at recruitment. Odds ratios for the development of ischaemic heart disease in the middle and upper thirds of the distribution for each variable in the controls, relative to the lowest third (and two-sided P-values for linear trends), were: 3.0, 2.6 (0.015) for Quetelet's index; 3.3, 5.1 (0.003) for total cholesterol; 0.5, 0.6 (0.102) for apolipoprotein A-I; 1.8, 2.4 (0.015) for apolipoprotein B; 1.3, 2.1 (0.155) for apolipoprotein(a). The increased risks associated with increased Quetelet's index and total cholesterol were independent of each other and these variables were more strongly related to myocardial infarction than to angina. The relationships of risk with serum cotinine, fatty acids, dehydroepiandrosterone sulphate and sex hormone binding globulin were weak and did not approach statistical significance.

We have studied hypertension, obesity, diabetes and hypercholesterolaemia in those aged 45-79 years in the Cretan low risk population of Spili (n = 249; attendance 82%) to see if these conditions interacted in the same way as previously described for high risk populations. Hypertension, diabetes, obesity, and hypercholesterolaemia were found to be at least as prevalent in Spili as in Sweden. Furthermore, the previously described 'Metabolic Syndrome X', with insulin resistance and hyperinsulinaemia as a common denominator also seemed to exist in the Spili population where patients with these conditions had higher insulin and C-peptide levels than normals. Our finding should be viewed against the low prevalence of past myocardial infarction in Cretan men from Spili reported by us and confirming the results of the Seven Countries Study.

Blood pressure reduction in hypertensive patients is a surrogate for the real therapeutic goal of reducing the risks consequent to hypertension. This surrogate is convenient but its use may have important therapeutic implications. Results of treatment with new antihypertensive agents, data from clinical trials, and insights into underlying mechanisms are reviewed. The overall success of antihypertensive therapy has been undeniable, but has reduced minimally the frequency of atherosclerosis and coronary events; metabolic disarray resulting from the agents used, especially thiazides and beta blockers, may have contributed to this. Electrolyte abnormalities predispose to malignant arrhythmias and sudden death during myocardial infarction. Left ventricular hypertrophy, a chief risk factor for coronary events, arrhythmias, and heart failure, responds selectively to antihypertensive agents. Similarly, progression of renal injury may be sensitive to the agents used. Obesity and hypertension frequently coexist. Evidence is growing that atherogenic abnormalities common in obese patients, such as insulin resistance, also occur in the nonobese patient and are sensitive to the antihypertensive agent selected.

Obvious, but often forgotten, is the premise that blood pressure reduction in the patient with hypertension is a surrogate for our real goal, which is reduction in the risks consequent to hypertension. This surrogate, a convenience for regulatory agencies, has therapeutic implications. As the array of antihypertensive agents available has grown, along with information from clinical trials and insights into underlying mechanisms, it has become reasonable to examine that premise. The overall success of antihypertensive therapy has been undeniable, but has not influenced the advance of atherosclerosis, primarily coronary events. Multiple observations suggest that metabolic disarray consequent to the use of antihypertensive agents, especially thiazides and beta-blockers, may have contributed to this scenario. Electrolyte abnormalities predispose to malignant arrhythmias and sudden death during myocardial infarction. Left ventricular hypertrophy, a major risk factor for coronary events, arrhythmias, and heart failure, responds selectively to antihypertensive agents. Similarly, the progression of renal injury in the hypertensive patient may be sensitive to the agents employed. Obesity and hypertension coexist frequently; moreover, evidence is growing that atherogenic abnormalities common in the obese patient, such as insulin resistance, not only occur frequently in the nonobese patient, but are also sensitive to the antihypertensive agent selected. Although predictions are risky, it seems safe to predict that the next chapter in antihypertensive therapy will examine whether we need to go beyond blood pressure reduction in selecting such therapy.

Of the major risk factors for atherosclerosis, high factor VII and fibrinogen levels, genetic predisposition, gender and age cannot be influenced. Reduction of high blood pressure reduces the cerebral but not the coronary vascular risk and correction of dyslipidaemia correlates with cardiovascular risk. Other major risk factors (tobacco consumption, obesity, sedentary lifestyle and diabetes) can also be modified. Aspirin in doses of approximately 300 mg/day may be recommended for the primary prevention of myocardial infarction (MI), but only in those patients with a moderate to high risk of cardiovascular disease. Aspirin reduces the risk of fatal and nonfatal MI by about 50% and also decreases the overall mortality rate among patients with unstable angina. A lower dose of aspirin (150 mg/day) also reduces mortality by 23% in the acute phase of MI. In doses of 300 mg/day, aspirin is useful in the secondary prevention of MI and reduces the overall mortality rate by 15%. Various antiplatelet agents, including aspirin (alone or combined with dipyridamole) and ticlopidine, have proved useful in the prevention of thrombosis in aorto-coronary grafts, provided treatment begins at the latest 6 hours after surgery. The usefulness of antiplatelet drugs has been well established in the prevention of immediate reocclusion following coronary angioplasty, but not in the prevention of late reocclusion. Aspirin and ticlopidine are also beneficial in extracorporeal circulation techniques. In patients with a synthetic cardiac valve prosthesis, antivitamin K-anticoagulants are still indispensable lifelong, but their antithrombotic effect can be reinforced by dipyridamole or aspirin. Diuretics probably provide the best primary protection against cerebrovascular accidents, although medium doses of aspirin may be considered in elderly people at high risk of such accidents. Aspirin (alone or combined with dipyridamole) and ticlopidine may be recommended for the secondary prevention of cerebral ischaemic accidents. Aspirin (with or without dipyridamole) and ticlopidine reinforce the treatment of obliterative arterial disease in the lower limbs.

Little information is available about the incidence of severe adverse outcomes, and even less information is available about the identification and quantification of independent predictors of severe perioperative adverse outcomes. The purpose of this study was to identify and quantitate independent predictors of severe perioperative adverse outcomes in a prospective randomized clinical trial of general anesthesia in 17,201 patients. Twenty-nine prognostic variables for 15 severe outcomes in 847 patients were tested by multiple stepwise logistic regressions from which 20 significant (P less than 0.05) predictors were identified. A history of cardiac failure or myocardial infarction less than or equal to 1 yr; ASA physical status 3 or 4; age greater than 50 yr; cardiovascular, thoracic, abdominal or neurologic surgery; and the study anesthetics were significant predictors of "any severe outcome, including death." There were 17 significant predictors for 10 severe cardiovascular outcomes in 608 patients, including a history of ventricular arrhythmia, hypertension, cardiac failure, myocardial ischemia, myocardial infarction less than or equal to 1 yr or myocardial infarction greater than 1 yr, and smoking; ASA physical status; age; cardiovascular, thoracic, abdominal, eyes-ears-nose-throat/endocrine, neurologic, musculoskeletal, or gynecologic surgery; and the study anesthetics. There were 9 significant predictors for 4 severe respiratory outcomes in 163 patients, including a history of cardiac failure, myocardial ischemia, or chronic obstructive pulmonary disease; obesity; smoking; male gender; ASA physical status; abdominal surgery; and the study anesthetics. Colinearity between related prognostic variables (such as disease and ASA physical status) was assessed using progressively segregated groups of variables in eight stepwise logistic regressions. We conclude that the comprehensive stepwise logistic regression of 29 prognostic variables reported here provides a valid estimate of the risks of severe perioperative outcomes associated with general anesthesia.

Our aim was to analyze the predictive value of a variety of preoperative risk factors on operative outcomes. We reviewed all colorectal resections performed in a single hospital between January 1985 and May 1990. Nine hundred seventy-two resections were performed on 825 patients. We studied 17 preoperative risk factors generated from various medical risk categories. Using the multivariate discriminant function analysis, we calculated that 11 of the 17 risks were of significance in predicting outcomes (all with P less than or equal to 0.031). These factors included emergent operation, age greater than or equal to 75 years, congestive heart failure (CHF), prior abdominal or pelvic radiation therapy, corticosteroid use, albumin less than 2.7 g/dl, chronic obstructive pulmonary disease (COPD), previous myocardial infarction (MI), diabetes, cirrhosis, and renal insufficiency. The classification function generated by the discriminant analysis was used to categorize patients into one of four risk groups depending on their "risk score." The index used to develop each patient's "risk score" ranged from six points for an emergency operation to one point for diabetes. The mortality rates for the various risk groups were as follows: Group 1, zero to four points, 1 percent; Group 2, five to eight points, 10 percent; Group 3, 9 to 13 points, 19 percent; Group 4, greater than 13 points, 33 percent. In contrast to previous reports, we showed that age greater than or equal to 75 years alone is not a major preoperative risk factor but, rather, acts as a modifier for the other predictors of postoperative complications. We then assessed clinical questions concerning specific preoperative risks, such as steroid use, obesity, inflammatory bowel disease, COPD, and prior laparotomy, and their associated specific postoperative complications and have developed prevention strategies based on these findings. Through the use of the risk index, we also were able to assess an individual patient's operative risk more accurately.
