The correlation between different antihypertensive treatments and prognosis of cardiovascular disease in hypertensive patients

OBJECTIVE: To determine the association between different antihypertensive regimens and cardiovascular disease (CVD) outcomes in hypertensive patients. METHOD: This single center retrospective cohort study analyzed 602 hypertensive patients with complete medical records at Zhongnan Hospital of Wuhan University, China, from January 2016 to November 2022. Baseline data and follow-up data of the included patients were collected, including demographic and clinical characteristics and laboratory results. RESULTS: During the 5-year follow-up period, CVD outcomes occurred in 244 hypertensive patients (40.53%). Compared with patients receiving regular antihypertensive treatment, the incidence of adverse cardiovascular events in patients receiving irregular antihypertensive treatment was significantly higher (62 [55.86%] vs 182 [37.07%], HR 1.642, 95% CI 1.227–2.197, p < 0.001). In subgroup analysis, the results showed that the incidence of CVD was not identical (χ2 = 9.170, p = 0.010). The incidence of adverse cardiovascular events was highest in the single-drug antihypertensive treatment group (43.60%), followed by the multi-drug combination group (41.51%), and lowest in the two-drug combination group (29.58%). Kaplan–Meier curve showed that hypertensive patients treated with two-drug combination antihypertensive had longer overall survival time. We further compared the incidence of CVD between standard blood pressure and intensive blood pressure control, and found no significant difference in the incidence of adverse cardiovascular events between treatment to a systolic blood pressure (SBP) target of less than 140 mmHg compared with a SBP target of less than 120 mmHg (105 [43.93%] vs 35 [29.66%], HR 1.334, 95% CI 0.908–1.961, p = 0.142). CONCLUSION: The incidence of adverse cardiovascular events was significantly different among different antihypertension treatments. Kaplan–Meier survival curve showed that hypertensive patients receiving two-drug combination antihypertensive treatment had longer overall survival time.
