Peak systolic blood pressure/end-systolic volume ratio: Assessment at rest and during exercise in normal subjects and patients with coronary heart disease

摘要: Abstract To assess the utility of a recently proposed index left ventricular performance, ratio peak systolic pressure to end-systolic volume, equilibrium radionuclide angiography was used determine volume and blood obtained by cuff sphygmomanometer pressure. Data were analyzed at rest during supine bicycle exercise in 15 normal subjects (Group 1), 50 patients with coronary artery disease II) 9 obstructive lung no evidence on clinical examination including thallium imaging III). In correlation between resting angiographic pressure/volume excellent (r = 0.929, p Forty-seven (94 percent) Group II had depressed or an abnormal change this exercise, whereas only 43 (86 group ejection fraction exercise. Additionally, 3 I response, defined as less than 0.05 unit increase (specificity 80 percent), all 100 percent). At rest, neither identified more other. Of nine III, six response one response. It is concluded that useful performance. some stress it may be sensitive alone identifying presence disease.
