Abstract

Abstract: There is currently few research on clinical characteristics and outcomes of coronary heart disease (CHD) with resistant hypertension in central region of China. This study aimed to assess the risk factors and outcomes of CHD and resistant hypertension in population of central region of China. A total of 1467 CHD patients with hypertension were included and considered to three groups according to blood pressure control: controlled group (blood pressure < 140/90 mmHg on three or less antihypertensive drugs); uncontrolled group (blood pressure ≥ 140/90 mmHg on two or less antihypertensive drugs); or resistant group (blood pressure ≥ 140/90 mmHg on three antihypertensive drugs or < 140/90 mmHg on at least four antihypertensive drugs including diuretic). The authors evaluated the clinical outcomes of three groups at 1‐year follow‐up. The prevalence of resistant hypertension was 21.8%. Significant adjusted associated factors of resistant hypertension included per unit changes body mass index (BMI, OR 1.12), and four categorical variable diagnosis by yes or no: heart failure (HF, OR 2.62), left ventricular hypertrophy (LVH, OR 2.83), diabetes (OR 1.55), and chronic kidney disease (CKD, OR 1.63). In multiple adjusted Cox regression analysis, patients in resistant group had a higher risk of the primary outcome (HR, 2.14 [95% CI, 1.47–3.11]; p < .001). Moreover, the risk of atherosclerotic cardiovascular disease (ASCVD) in patients with resistant hypertension is also significantly increased (HR, 2.11 [95% CI, 1.39–3.20]; p < .001). In conclusion, resistant hypertension was a quite common and high proportion finding in patients with CHD and hypertension in central region of China, and these patients have a worse clinical prognosis.
