[Comparative characteristics of the hemodynamic changes in virtually healthy persons and in ischemic heart disease...

Comparative studies on changes of hemodynamics in manual and leg isometric loads were conducted in 30 healthy persons and 38 patients with coronary heart disease. A possibility of a leg isometric load with a maximum effort for 5 min. was shown. Intracardiac hemodynamics was estimated by echocardiography results. A possibility to reveal early stages of myocardial contractile and pumping function in patients with coronary heart disease was established. Manual dynamometry does not permit revealing early stages of heart insufficiency.
