Abstract: By using a noninvasive synchronous ventricular function detector （NISVFD）,the cardiac function capacity in 95 patients with decreasing ejection fracton（EF） was determined,with 39 normal subjects as controls. The stroke volume（SV） and stroke index （SI） in patients with decreasing EF decreased significantly as compared with those in the normal group. This decrease was mainly due to myocarditis, essential hypertension（EH） and coronary heart disease（CHD）. The incidence of decreasing EF was higher in male than in female. In patients with EH,CHD,pumonary heart disease,rheumatic heart disease and myocarditis,the five common cardiovascular diseases,the resistance total mean （RTM） was higher than in the normal subjects （P＜0.01）. RTM was the main risk factor in 95 patients with decrasing EF. RTM increase was due to such factors as elevated blood viscosity, arginine vasopressin, in addition to EH and CHD.Our results suggest that the use of a NISVFD helps us not only to understand the severity in CHD,EH and myocarditis and in especial decreasing EF patients, but also to follow up survey of results of medicinal effect and prognosis.
