摘要
Abstract
Objective:To investigate changes of myocardial blood supply and cardiovascular function when coronary heart disease patients undertake exer⁃cise,and to provide a simple manner for them to monitor cardiac ischemia by applying rate pressure product. Method:Fifty-four male recent coronary heart disease patients performed a graded exercise test on a treadmill. Both heart rate and systolic/diastolic blood pressure were measured at the last minute of I ,II and III exercise stage. Rate-pressure product was then calculated by multiplying heart rate by systolic blood pressure and divided the product by 100. A 12 lead electrocardiogram was monitored continuously and from which changes of ST segment level could be found. Results:1)The patients with less ST seg⁃ment depression during exercise showed a light cardiovascular response at the moment. Whereas those with more ST segment depression not only depicted a significant cardiovascular response at exercise stage I but also presented much increase for this response thereafter. 2)The patients with ST segment depres⁃sion reaching 1 mm at exercise stage III of the modified Bruce treadmill protocol demonstrated a relative large rate pressure product value ,over 200 for in⁃stance. Conclusions:Cardiovascular status and state of health of the subjects can be reflected by rate pressure product response. We should be aware that if rate pressure product shows a sudden increase when coronary heart disease patients undertaking exercise during rehabilitation ,it might be related to underly⁃ing myocardial insufficiency.关键词
