Studies on coronary circulation in coronary sclerosis.

چکیده
In coronary sclerotic patients with a fixed coronary vascular resistance, coronary blood flow is to be directly regulated by perfusion pressure. In this report, an analysis of perfusion pressure was carried out regarding coronary blood flow, myocardial oxygen consumption, and myocardial oxygen supply. Fourteen patients with coronary sclerosis were studied. In resting state, mean diastolic pressure calculated from brachial arterial pressure curve was significantly related with coronary blood flow. The product of mean diastolic pressure and heart rate was more linearly correlated with coronary blood flow. The relation of these factors with coronary blood flow was discussed in reference to the myocardial oxygen consumption. Also, mean diastolic pressure was similarly correlated with myocardial oxygen supply. In this result the author concludes that diastolic mean pressure is more important factor to regulate coronary blood flow or myocardial oxygen supply in coronary sclerotic patients.

متن کاملPhysical fitness and coronary heart disease. Some basic views.
The purposes of a physical training program are examined and the evidence for the general and circulatory benefits of physical fitness is discussed. While the proof of benefits is not established, there is sufficient evidence from current studies to justify encouragement of the exercise programs. The evidence that exercise lessens experimental atherogenesis is equivocal. The possibility that ph...
