The rates of decrease of FS and EF% (by Simpson and Teichholz method) and increase of left ventricular end systolic volume (ESV) and left ventricular end diastolic volume (EDV) in the patients with ischemic ST-T changes were higher compared with that in the patients without ischemic ST-T changes (p < 0.05). Conclusions: Left ventricular systolic function was significantly decreased in people with angina pectoris, especially in angina patients with old myocardial infarction and ischemic ST-T changes.
