Abstract

Objectives To investigate the current status of blood pressure (BP) treatment-goal in outpatients with coronary heart disease (CHD) in China and to identify the independent risk factors of BP treatment goal achievement in these outpatients.

Methods In this cross-sectional survey, participants with CHD aged ≥35 years were recruited from 66 hospitals from June 2006 to January 2007 in Beijing, Shanghai, Tianjin, Guangdong, Zhejiang and Xinjiang in China.

Results 68.6% of the subjects had hypertension (female 76.0% vs male 64.5%, p<0.001). The goal of BP achievement was SBP<130 mm Hg and DBP<80 mm Hg for CHD outpatients in this study. The success rate for achieving the BP target in CHD outpatients was 26.4% (female 23.1% vs male 28.3%, p<0.001). The success rate for achieving the BP target in CHD outpatients was 18.1%. The independent risk factors of achieving the BP target for CHD outpatients with hypertension were BMI ≥23 kg/m2, minority nationalities and use of statins. The OR of these risk factors were 1.423 (95% CI 1.171 to 1.729), 0.438 (95% CI 0.279 to 0.686) and 0.768 (95% CI 0.593 to 0.995), respectively. The incidence of acute myocardial infarction, percutaneous coronary intervention and coronary artery lesions were significantly higher in CHD outpatients with SBP <110 mm Hg and/or DBP<60 mm Hg than those in CHD outpatients with SBP ≥110 mm Hg and DBP ≥60 mm Hg (p<0.001).

Conclusion This survey demonstrated the success rate for achieving the BP target was low in Chinese CHD outpatients, especially in CHD outpatients with hypertension. BMI ≥23 kg/m2, minority nationalities and use of statins were the independent risks of achieving the BP target for CHD outpatients with hypertension.
