Blood pressure control rate and associated risk factors in hospitals of different grades in Chongqing, China.

OBJECTIVE: The present article aimed to provide accurate estimate of the control rate of hypertension and the influencing factors in hospitals of different grades in Chongqing. METHODS: In this survey, hypertensive outpatients were recruited from 5 tertiary hospitals, 6 secondary hospitals and 5 primary hospitals in 9 districts of Chongqing from November 2011 to May 2012. Outpatients were investigated by clinical interview with BP measurement and questionnaire. Univariate analyses and logistic regression analysis was used to assess the effect of variables on control of hypertension. RESULT: A total of 2742 hypertensives were studied, of which 820 were from primary hospitals, 901 from secondary hospitals and 1021 from tertiary hospitals. The total control rate for hypertensive outpatients in Chongqing was 46.0%. The control rate of the primary,secondary and tertiary hospitals were 38.7%、46.7%、51.1%. Multinomial Logistic Regression showed that the control rate was positively correlated with mastery of knowledge of hypertension, normal BMI;whereas it was positively correlated with peasantry,the dissatisfactory with doctor's manner and the distrust to doctor. CONCLUSION: Blood pressure control rate of hypertensive outpatients in Chongqing was low.High BMI, peasantry, lack of knowledge of hypertension, doctors' manners, distrust to doctor were the key reasons for low BP control rate.

[A meta-analysis on efficacy of intra-aortic balloon pump therapy in patients with acute myocardial infarction].

OBJECTIVE: To analyze the efficacy and safety of intra-aortic balloon pump (IABP) therapy in patients with acute myocardial infarction(AMI) based on the meta-analysis. METHODS: Eligible published randomized controlled clinical research (RCT) were retrieved in the Pubmed, EMBase, Cochrane, China biological medical literature, Wanfang, VIP and CNKI database from 1980 to April 2, 2012. The analysis was performed with the software of RevMan 5.1. RESULTS: Thirteen RCTs with 1958 patients (AMI with IABP therapy, n = 970,without IABP therapy, n = 988) were included. The 30-day mortality between the two groups was similar (RR = 0.77, 95%CI 0.58-1.03, P = 0.08), but the 30-day mortality in the cardiac shock subgroup was significantly lower in IABP group than in without IABP group (RR = 0.65, 95%CI 0.44-0.97, P = 0.04). The 6-month mortality was significantly lower in IABP group than in without IABP group (RR = 0.72, 95%CI 0.55-0.94, P = 0.02). The incidence of major bleeding was significantly higher in IABP group than in without IABP group (RR = 1.43, 95%CI 1.16-1.75, P < 0.01). CONCLUSION: IABP therapy is effective to reduce earlier mortality post AMI, particularly for patients with cardiac shock.
