ABSTRACT
Objective To investigate the effect of atorvastatin intensive therapy on cardiac function and lipoprotein phospho‐lipase A2 (Lp‐PLA2) in patients with hypertension complicated with ST segment elevation acute myocardial infarction .Methods Totally 78 patients with hypertension complicated with ST segment elevation acute myocardial infarction from June 2014 to April 2016 in our hospital patients ,according to the random number table method divided into observation group (atorvastatin therapy ) and control group (routine treatment) .The changes of blood pressure ,blood lipid ,Lp‐PLA2 ,cardiac function of two groups were compared before and after treatment .Results Before treatment ,there was no significant difference in blood pressure and blood lipid between the two groups (P>0 .05) .After treatment ,the two groups of patients with SBP ,DBP ,LDL‐C significantly decreased , HDL‐C significantly increased ,and compared with the control group ,the SBP ,HDL‐C ,LDL‐C in the observation group were signif‐icantly different (P0 .05) . After treatment ,the two groups of patients with Lp‐PLA2 were significantly reduced ,and the observation group was significantly greater (P0 .05) .Af‐ter treatment ,the observation group of patients with LVESD ,LVEDD significantly decreased ,LVEF ,CO ,CI significantly in‐creased ,compared with the control group ,the difference was statistically significant (P<0 .05) .Conclusion Atorvastatin intensive therapy can significantly reduce high blood pressure acute ST segment elevated blood pressure and Lp‐PLA2 levels in patients with acute myocardial infarction and improve cardiac function ,worthy of promotion .
ABSTRACT
OBJECTIVE: To investigate the effects of carvedilol on blood pressure in hypertension patients and vascular endothelial function. METHODS: 100 inpatients with primary hypertension were collected from our hospital from Jan. 2008 to Jan. 2010 and randomly divided into treatment group and control group(n=50). Treatment group were given initial oral dose of carvedilol tablets 6.25 mg twice a day for 7～14 days if it was tolerated; the dose of carvedilol tablets increased to 12.5 mg or 25 mg twice a day according to blood pressure at trough concentration if it was necessary. Control group were given carvedilol tablets 6.25 mg twice a day if it was tolerated. After 1 week, control group received double dose of metoprolol with maximum dose of carvedilol of 50 mg. The treatment course was 3 months. The contents of NO and ET in serum of 2 groups were detected. Antihypertensive effect and effects of carvedilol on vascular endothelial dilatation and systolic function were observed and compared between 2 groups. RESULTS: After treatment, the systolic and diastolic blood pressure in both groups were decreased significantly(P
