RESUMO
Objective: To investigate the current status and influence factors of ACEI/ARB application in elderly coronary heart disease outpatients complicated with diabetes mellitus in 21 provinces of China. Methods: In this multicenter, non-intervention and cross-sectional survey, the elderly coronary heart disease patients aged 60 years or over were recruited from 165 hospitals in 21 provinces across China from April to July 2011. Current status and influence factors of ACEI/ARB application among 1 789 cases with diabetes mellitus were investigated in the survey. Results: Totally, 1 069 patients used ACEI/ARB drugs (59.8%); proportion of ACEI (544 cases, 30.4%) drugs were the same as ARB drugs (533 cases, 29.8%) in terms of usage of drug types, and combination of the two drugs were taken by 28 cases (1.6%) at the same time. ACEI/ARB usage decreased with the increasing of age, and the rate of drug usage in male patients was slightly higher than that in female, however there was no statistical difference (both P>0.05); the rate of usage of ACEI/ARB drugs gradually decreased with increasing of coronary heart disease or diabetes duration (P<0.05); the rates of usage of ACEI/ARB drugs in hypertension, dyslipidemia, myocardial infarction, renal insufficiency patients and patients received revascularization therapy were significantly higher (all P<0.05). Multivariable logistic regression analysis showed that hypertension (OR=3.016, 95%CI: 1.376-4.887), dyslipidemia (OR=1.489, 95%CI: 1.114-2.031), revascularization (OR=2.291, 95%CI: 1.276-3.277), myocardial infarction (OR=2.561, 95%CI: 1.571-4.545), renal insufficiency (OR=1.337, 95%CI: 1.145-2.013), and insulin treatment (OR=1.584, 95%CI: 1.084-2.511) were positively correlated with ACEI/ARB usage (P<0.05); and coronary heart disease duration was negatively correlated with ACEI/ARB drugs usage (duration 5-10 years: OR=0.621, 95%CI: 0.416-0.823; duration >10 years, OR=0.664, 95%CI: 0.471-0.840). Conclusions: The rate of usage of ACEI/ARB drugs in elderly coronary heart disease outpatients complicated with diabetes mellitus is still low, however, patients with hypertension, dyslipidemia, myocardial infarction, renal insufficiency and patients received revascularization therapy and insulin treatment are more likely to use ACEI/ARB drugs.

Objective: To explore the influences of body mass index (BMI) on blood pressure control rate in elderly coronary heart disease (CHD) outpatients with hypertension. Methods: In this multicenter, non-intervention and cross-sectional survey, the elderly coronary heart disease patients with hypertension aged 60 years or over were recruited from 165 hospitals in 21 provinces or cities across China from April to July 2011, and 5 140 cases of elderly CHD patients with hypertension were finally included into the study. The cases were divided into low BMI group (n=130 cases), normal body mass index (BMI) group (n=1 390 cases), overweight (n=2 418 cases), obesity group (n=662 cases) according to the different levels of BMI. Clinical data and blood pressure control rate were compared among the groups, and relationships of different BMI levels with blood pressure control rate were analyzed by the binary classification unconditioned Logistic regression equation. Results: There was a statistically significant difference in blood pressure control rate of general population, men and women patients among low BMI group, normal BMI group, overweight and obesity group (χ2=66.346, 58.995, 26.044, respectively, P<0.001), blood pressure failure rate in obesity group (73.7%) was higher than that in overweight group (65.8%) and normal BMI group (57.5%) (P<0.05), and overweight group was also higher than normal BMI group (P<0.05); blood pressure failure rate in obesity men was higher than that in normal BMI and low BMI group (P<0.05), overweight group was higher than normal BMI group (P<0.05); blood pressure failure rate in obesity women was higher than that in normal BMI and low BMI group (P<0.05). There was a statistically significant difference in blood pressure control rate of different age groups (60-70, 71-80, >80 years old) among low BMI group, normal BMI group, overweight and obesity group (χ2=37.729, 20.007, 15.538, respectively, P<0.001). Blood pressure failure rate in obesity patients with 60-70 years old was higher than that in overweight and normal BMI group (P<0.05), blood pressure failure rates in obesity and overweight patients with 71-80 and > 80 years old were also higher than those in normal BMI group (P<0.05). Multivariable Logistic regression equation showed that overweight in overall population (OR=1.313, 95%CI 1.170-1.731, P<0.05), obesity (OR=2.295, 95%CI 2.295-1.496, P<0.05) were independent risk factors for blood pressure failure rate, in addition, obesity was also risk factor for blood pressure failure rate in men and women patients. Conclusions: Increased BMI has an adverse effect on blood pressure control rate in elderly CHD outpatients with hypertension, and may be the independent risk for blood pressure failure rate in those patients. Much more attention should be given to control BMI level so as to increase the blood pressure success rate and improve the patients' prognosis.
