RÉSUMÉ
Objective To investigate the effect of xuezhikang on heart in patients with hypertension. Meth-ods 60 systemic hypertension (HT) patients with normal cholesterol were randomized into placebo group and Xu-ezhikang group (1200 mg/d) for 72 weeks. Extended-released nifedipine were administrated by HT patients. Plasma was obtained at baseline, after 24 weeks and 72 weeks of Xuezhikang therapy. Em/Am ratio at atrioventricular ring , E/A ratio at mitral orifice, IVSTd, LVIDd, LVPWTd were measured by echocardiography. Type Ⅰ collagen car-boxypropeptide (PIP) was determined. Results After 72 weeks treatment, the differences of LVWT, IVSTd, LVP-WTd and LVIDd between Xuezhikang group and the control group were not significant; E/A,Em/Am ratios at atrio-ventricoiar ring were significantly increased except that Em/Am at right atrioventricular ring with right ventricular lateral wall(P <0.01 ,P <0.05). After 24 weeks treatment the levels of plasma PIP were significantly decreased in Xuezhikang group compared with the placebo group (P < 0.01, P < 0.05). Conclusion Xuezhikang exerts cooper-ativity in improving those parameters related to myocardial fibrosis so to protect heart function of hypertension pa-tients.

LAVP2. Multiple linear regression revealed duration of hypertension, grade of hypertension, age and smoking status were independent determinants for the deterioration of diastolic dysfunction. Conclusion A progressing change in regional diastolic dysfunction from right to left ventricle was found in HT patients. The grade of hypertension and the duration of HT were the major determinants on diastolic dysfunction.
