Im C, et al. - By performing this retrospective cohort analysis, researchers investigated the link between the use of preoperative antihypertensive medication and postoperative 90-day mortality among the adult population that underwent elective non-cardiac surgery and had hypertension. Two groups of patients were defined: the HTN MED group, including hypertensive patients who were prescribed to receive antihypertensive medication continuously for more than 1 month prior to admission; and the non-HTN MED group, comprising others. This study included a total of 35,589 preoperative hypertensive adult patients, including 26,154 patients in the HTN MED group and 9,435 in non-HTN MED group. Findings revealed lower 90-day mortality related to the use of preoperative antihypertensive medication among patients with hypertension who underwent non-cardiac surgery. Thus, preoperative screening and management with appropriate antihypertensive medication are crucial for patients having hypertension.
