AIM:To investate the effect of domestric moxonidine hydrochloride on myocardium fibrosis and coronary artery microvascular structure in left ventricular hypertrophy of spontaneously hypertensive rats(SHR).METHODS:30 male SHR, aged 20 weeks, were divided into group Mox+SHR, Cap+SHR and SHR randomly (10 in each group). 10 age and sex-mached sprauge-dawley rats were designed as normal control(NC). At the end of 13 weeks, left ventricular wight/body weight ratio(LVW/BW), collagen volume fraction(CVF) and standardized perivascular collagen area(PVCA) as well as intramyocardial arterial average medial thickness (AMT) were determined.RESULTS:LVW/BW, CVF, PVCA and AMT in group Mox+SHR were lower significantly than that in group SHR, respectively.CONCLUSION:Long-term antihypertensive treatment with moxonidine hydrochloride reduces myocardium fibrosis and improves impaired coronary artery microvascular structure in left ventricular hypertrophy. 相似文献
