摘要:

The argument against the participation of postcoronary patients in marathon (42 km) jogging is critically evaluated. It is demonstrated that the majority of patients referred for exercise rehabilitation have the necessary potential to undertake marathon training. However, psychosocial considerations limit candidates to 1/3 to 1/2 of the sample, and the number interested in such intensive preparation is only 1% to 2% of a typical postcoronary class. To date, the safety of such activity for well-trained and carefully supervised patients is most encouraging. Moreover, the long-term impact on smoking habits, lipid profile, and cardiac work rate is impressive. Participants show substantial correction of reactive depression, and there is a “spillover” of enthusiasm to other class participants.

摘要:

The purpose of this study was to compare maximal cardiorespiratory and serum lipoprotein values in 53 male distance runners with values in 53 sedentary men matched by age, height, body weight, and body fat. There was no significant difference between the runners and sedentary men in age, height, body weight, lean body mass, body fat, or maximal exercise heart rate. However, the runners had significantly greater maximal aerobic power. There were no significant differences between the groups in cholesterol and low-density lipoprotein cholesterol (LDL-C) + very-low-density lipoprotein cholesterol (VLDL-C), but the runners had significantly higher high-density lipoprotein cholesterol (HDL-C) and HDL-C/cholesterol ratio. In both groups, cholesterol, LDL-C + VLDL-C, and triglycerides were linearly related to body fat, whereas maximal oxygen uptake (VO2 maxand HDL-C/cholesterol were inversely related to body fat. In the runners, VO2 maxwas linearly related to HDL-C/cholesterol and inversely related to triglycerides, cholesterol, and LDL-C + VLDL-C. High-density lipoprotein cholesterol was inversely related to body fat; that relationship was not statistically significant. In all subjects, LDL-C + VLDL-C and triglyceride levels were inversely related to HDL-C, whereas LDL-C + VLDL-C and triglyceride values for any given level of HDL-C were significantly lower in the runners compared with the sedentary men. Our findings suggest that distance running does not affect cholesterol and LDL-C + VLDL-C levels but is associated with significantly lower triglyceride levels and significantly higher HDL-C levels.

摘要:

The subscales of the Jenkins Activity Survey were examined in relation to a maximum expiratory exchange ratio derived from graded exercise test (GXT) data and ratings of perceived exertion in a sample of 44 patients referred to the Wake Forest Cardiac Rehabilitation Program. A canonic correlation produced one significant variate pair (canonic R = .59). Interpretation of this multivariate analysis suggested that type A individuals, in particular those who exhibit such behavior in conjunction with job-related activities, put forth greater effort during their GXT and appeared to manifest some degree of fatigue suppression. These results would appear relevant to both the evaluation of subjective data by medical personnel during GXTs and the process of exercise prescription.

摘要:

Coronary heart disease (CHD) has a multifactorial etiology with risk factors including age, sex, hypertension, smoking, diabetes mellitus, and serum cholesterol. Some of these are amenable to change. Few physicians question the wisdom of control of hypertension or the evils of smoking. More controversial is the effect of dietary intervention in affecting serum cholesterol and risk of CHD.Epidemiologic evidence is presented from the literature supporting the concept that diets adequately limited in total cholesterol result in low serum cholesterols and a lower incidence of CHD. Although the pathogenesis of atherosclerotic CHD remains unclear, serum cholesterol is pivotal in the disease process.Reversibility of atherosclerosis is addressed, and the studies supporting this phenomenon are reviewed. The evidence in animals is broad and consistent, but extrapolation to humans is difficult. A significant amount of evidence supports the possibility of reversal of atherosclerosis in humans; younger lesions are more amenable to reversal. Angina and myocardial infarction are manifestations of a disease process that is usually silent for decades. Perhaps early intervention prior to disease manifestation is the proper approach to the CHD epidemic.

摘要:

Five studies that have attempted to evaluate the outcome of group therapy for patients who have suffered a myocardial infarction are reviewed. Positive findings included modification of type A behavior, increased employment, fewer reinfarctions, and less social isolation. Negative findings were increased anxiety and raised serum cholesterol. Overall, the therapy appeared to be beneficial; however, two studies had small numbers of patients and no study used blind observers for rating patients. No author examined the best time to begin therapy, the optimum amount of therapy, whether certain subgroups of patients (e.g., women and elderly) might benefit more from therapy, or whether group therapy produced better results than other types of psychotherapy. Consequently, more work is required in this field.

摘要:

It has come to our attention that readers of the Journal of Cardiac Rehabilitation would welcome regular information on particularly interesting case studies in cardiac rehabilitation. We concur and believe that by sharing the medical, physical, and psychologic idiosyncrasies involved in the rehabilitation of an individual patient discussion will be stimulated and thought will be broadened in all areas of cardiac rehabilitation. Thus, we invite authors to submit reports on particularly challenging cases in cardiopulmonary rehabilitation to be published as a periodic feature of the journal.
