Effects of High Blood Pressure on Cardiovascular Disease Events Among Chinese Adults With Different Glucose Metabolism

OBJECTIVETo investigate cardiovascular disease (CVD) risks caused by blood pressure (BP) of 130-139/80-89 mmHg among Chinese adults with different glucose metabolism.RESEARCH DESIGN AND METHODSA prospective population-based cohort of 2,132 adults in Shanghai was established in 2002, and CVD information was collected during 10.9 years of follow-up. After assessing the association between BP categories and incident CVD, we analyzed the risk for CVD by blood glucose categories and BP categories combined by using multiple Cox regression analysis among 1,419 participants at follow-up.RESULTSThe corresponding incidence of CVD per 1,000 person-years for the BP <130/80 mmHg, 130-139/80-89 mmHg, and 140/90 mmHg or treated groups were 3.0, 6.0, and 13.9, respectively. After adjusting for age, sex, and other factors, BP 140/90 mmHg was significantly associated with a higher CVD risk in general (hazard ratio 2.68 [95% CI 1.36-5.25]) and in various blood glucose categories (normoglycemia 2.59, prediabetes 3.03, diabetes mellitus [DM] 4.98). However, BP of 130-139/80-89 mmHg was significantly associated with a higher CVD risk in an estimated baseline 10-year atherosclerotic CVD (ASCVD) risk 10% (3.82 [1.42-9.78]) or DM (3.54 [1.05-11.88]) but not in the general population or for a baseline 10-year ASCVD risk <10%, normoglycemia, or prediabetes.CONCLUSIONSBP of 130-139/80-89 mmHg may result in a significantly higher CVD risk in Chinese adults with an estimated 10-year ASCVD risk 10% or DM but not in those with normoglycemia or prediabetes.
