title: [The changes of erythrocyte deformability and cardial function in coronary heart disease with various degrees of coronary stenosis].
abstract: According to the extent of coronary maximal stenosis, 29 cases of coronary heart disease (CHD) were classified into two groups: (I) obvious stenosis (OS, narrowing > or = 50% in luminal diameter, n = 15); (II) mild stenosis (MS, marrowing < 50% in luminal diameter, n = 14). The results showed that erythrocyte deformability index (DI), left ventricular ejection fraction (EF%) and fractional shortening (FS%) in the CHD patients were decreased as compared with those in the control group (P < 0.05 or 0.01), and the DI, EF and FS in the OS group were significantly lower than those in the MS group (P < 0.05). These suggest that DI, EF and FS may be of predictable value in identifying CHD patients with or without significant coronary stenosis.
