Abstract:Objective To explore the clinical characteristics and prognosis of patients with resistant hypertension and coronary artery disease.Methods We evaluated 1030 patients with coronary artery disease. According to the currently accepted definition of resistant hypertension, the secondary causes of resistant hypertension were excluded. The primary outcome was major cardiovascular events, including fatal coronary heart disease, nonfatal myocardial infarction and stroke.Results Among the 1030 patients in this study, 88 (8.5%) had apparent resistant hypertension. In a multivariable model adjusting for baseline differences, the resistant hypertension group had an increased primary outcome when compared with the no apparent resistant hypertension group. A multivariate analysis showed that older age, higher BMI, a history of diabetes and chronic heart failure were independent risk factors for resistant hypertension.Conclusions In patients with coronary artery disease, resistant hypertension is associated with a significant increase in the risk of cardiovascular morbidity and mortality. Clear diagnoses and effective treatment are of great importance.
