摘要:

In an earlier study (J Cardiol Rehabil 1982;2:280–286.), we demonstrated that exercise cardiac output (Qex) at two minutes of exercise was reduced in IT of 20 subjects with coronary artery disease (CAD). In the present study, toe used the same method of estimating Qexwith the exception that the ascending exercise sequence was continued until venoarterial C02difference in all subjects reached or exceeded 0.116 L/L, The score obtained from the study was expressed as &OV0312;O2(&OV0312;O2)- This score wan compared with the anaerobic threshold (AT). Mine male subjects with CAD, of whom six were receiving propranolol, were compared with nine normal male subjects. There was no correlation between &OV0312;O2116 and AT in the normal subjects, but in the nine subjects with CAD the relationship was significant: &OV0312;O2116=-0.16 +0.95 X AT, r = .83, F < ML in the case of both &OV0312;O2116 and AT, the values in the subjects with CAD were significantly reduced below those of the healthy group. We conclude that in evaluating patients with suspected left ventricular dysfunction, both the two-minute tests for Qexand the test for AT have potential usefulness because both tests identify the same patients as abnormal.

摘要:

A cohort of 4,427 healthy male fire fighters and law enforcement personnel received complete examinations including exercise measurements and assessments of other coronary disease risk factors. From 1972 to 1983, 77 major coronary events were documented. These events consisted of 55 symptomatic myocardial infarctions, 21 coronary bypass operations, and one coronary angioplasty. Three controls were matched to each case by year of age, year of examination, occupation, and sex. Before the coronary events, the affected patients had significantly lower physical work capacities, smoked more, had higher cholesterol levels, and had higher blood pressure than their controls. Discriminant analysis teas performed. The analysis indicated an important joint action of risk factors for the coronary events. The best discrimination of coronary cases (P <.001) was obtained with the variable in which each risk factor was measured on a probit scale of one to nine.

摘要:

The purpose of the present study was to perform a multimeihod assessment of the Type A behavior pattern in a sample of patients with coronary artery disease (CAD) participating in a cardiac rehabilitation program and to examine the relationship between Type A behavior and the severity of previously determined CAD. Results, based on the Structured Interview, indicated a preponderance of Type A behavior among the 52 patients. Other Type A measures, the jenkins Activity Survey. Framingham Type A Scale, and Bortner Type A Rating Scale, showed more normal distributions of patient scores. The relationship between the behavior pattern and CAD was affected by the method of determining Type A behavior and the method of determining CAD severity. Type A behavior, assessed by the Structured Interview, demonstrated a significant association with CAD severity only with adjustment for additional CAD risk factors. Thus, discrepancies in previous investigations may be explicable in terms of the measurement of both Type A and CAD as well as the presence or absence of more traditional risk factors. Finally, Type A behavior may be a CAD risk factor throughout adulthood.

摘要:

Thirteen men and ten women who had had a myocardial infarction were studied by 24-hour ambulatory electrocardiographic (ECG) monitoring, during which time they had sexual intercourse, No statistical difference was found between male and female patients in peak heart rate, percent of maximum-age-calculated heart-rate, or duration of sexual intercourse. Peak heart rate did not exceed, in any case, that caused by slight to moderate exercise. Four female patients experiencing sexual intercourse for the first time after infarction showed the lowest percent of maximum-age-calculated heart-rate. A marked increase was recorded in these patients during a second experience J5 days later, during which time they underwent physical and psychologic rehabilitation. Of 11 patients (nine men and two women) with premature ventricular contractions (PVCs) before coitus, only one man maintained arrhythmia during sexual intercourse. Of the 11 patients with PVCsfive recorded a lower PVC rate after sexual intercourse, during sleeping hours, compared with the rate they had before sexual activity. Two female patients had anginal pain and ST-segment depression during sexual activity, accompanied by a heart rate lower than or equal to the peak heart rate reached during intercourse, suggesting a coexisting vasospastic component in their angina.
