In order to clarify the hemodynamic characteristics in essential hypertension (HT) with angina pectoris (AP), systolic time intervals (STIs) were measured in 13 normal subjects (N), 23 patients with AP, 43 HT (WHO stage I: 13, WHO stage II: 23, WHO stage III: 7) and 19 HT with AP (WHO I: 9, WHO II: 10). The ET/PEP ratio was 2.41±0.24 in N, 2.70±0.34 in AP (p<0.02, vs N), 2.25±0.29 in WHO I, 2.13±0.25 in WHO II (p<0.01, vs N), 1.54±0.37 in WHO III (p<0.001, vs N), 2.68±0.32 in WHO I with AP (p<0.05 vs N: p<0.005, vs HT) and 2.71±0.30 in WHO II with AP (p<0.02, vs N: p<0.001, vs HT). Ejection time index (ETI) was 385±15 msec in N, 399±16 in AP (p<0.05, vs N), 387±13 in WHO I, 385±15 in WHO II, 363±25 in WHO III (p<0.05, vs N), 393±16 in WHO I with AP and 402±15 in WHO II with AP (p<0.05, vs N: p<0.01, vs HT). Pre-ejection period index (PEPI) was 142±10 msec in N, 135±11 in AP, 148±12 in WHO I, 156±13 in WHO II (p<0.005, vs N), 192±24 in WHO III (p<0.001, vs N), 134±13 in WHO I with AP (p<0.05, vs HT) and 136±9 in WHO II with AP (p<0.001, vs HT). These results showed that the ET/PEP ratio in HT with AP was significantly higher than that in HT alone, and this increase in ET/PEP ratio was mainly due to the shortening of PEP interval in WHO stage I and the lengthening of ET in addition to it in WHO stage II. Thus, the changes of STIs in essential hypertension, but identical with those in patients with angina pectoris.
