Diastolic and systolic parameters of left ventricular performance were characterized from high-frequency time-activity curves obtained in 10 normal volunteers (mean age 29 +/- 4 yr), 25 patients with coronary arteries, 50 artery disease (CAD) at rest during three stages exercise radionuclide angiography. In the ejection fraction was 65 5% (SD) 78 (p less than .001). arteries 64 72 8% .0001). CAD resting 60 10% that 61 13% = NS). Peak diastolic filling rate first half diastole, peak rate, times to rates end-systole measured. subjects 3.1 0.6 end-diastolic counts/sec it increased all 3.6 0.7 .05). those 2.3 0.8 this parameter 3.2 1.1 .001) fell 1.7 decreased 2.5 1.9 .001).(ABSTRACT TRUNCATED AT 250 WORDS)
