The rate-pressure product as an index of myocardial oxygen consumption during exercise in patients with angina pectoris.
In order to evaluate hemodynamic predictors of myocardial oxygen consumption (MVO2), 27 normotensive men with angina pectoris were studied at rest and during a steady state at sympton-tolerated maximal exercise (STME). Myocardial blood flow (MBF) was measured by the nitrous oxide method using gas chromatography. MBF increased by 71% from a resting value of 57.4 +/- 10.2 to 98.3 +/- 15.6 ml/100 ...

15 صفحه اولRate-pressure product correlates poorly with myocardial oxygen consumption during anaesthesia in coronary patients.
In 26 patients having coronary grafts, haemodynamics, coronary sinus blood flow and the arterio-coronary sinus difference of oxygen content were determined, awake and at four intervals during morphine-oxygen or halothane--oxygen anaesthesia. Rate-pressure product (RPP), triple product (TP) and myocardial oxygen consumption (MVO2) were calculated. The correlation of the two indirect indices to M...
متن کاملHand Grip Strength and Myocardial Oxygen Consumption Index among Coronary Artery Bypass Grafting Patients
Background: Hand grip strength (HGS) is a reliable indicator of peripheral muscle strength. Although, numerous studies have investigated the strength of hand grip; little attention has been given to coronary artery disease (CAD) patients, exploring the relationship between HGS and myocardial oxygen consumption (MVO2) index. The current study aimed to evaluate the interaction between HGS and MVO...
