Abstract

Objectives: Cardiovascular diseases are mainly related to hypertension and dyslipidemia and increase with aging because of the larger time span for these risk factors to damage arterial blood vessels. The impact of cardiovascular drug therapy on outcomes in the very elderly hospitalized is still not well established. The aim of our study was to evaluate the associations between cardiovascular therapy and in-hospital mortality in very elderly hypertensives. Design: Prospective observational study. Setting: Hospital assessment. Participants: 310 very elderly hypertensive patients admitted to our Internal Medicine and Geriatrics Department for medical conditions. Measurements: Main comorbidities, laboratory parameters, and cardiovascular drug therapy taken before admission were considered for the analyses. Results: The mean age was 88.1 ± 5.1 years, with female prevalence of 57.4%. Among cardiovascular drugs taken before admission, angiotensin-converting enzyme (ACE) inhibitors/angiotensin receptor blockers and statins were those associated with lower in-hospital mortality, even after adjusting for covariates (age, hemoglobin, albumin, acute kidney injury, ADL Hierarchy Scale, NT-proBNP levels) [odds ratio (OR) = 0.46, P = .045, and OR = 0.21, P = .008, respectively]. No difference regarding in-hospital mortality was found between ACE inhibitors and angiotensin receptor blockers (P = .414). Conclusion: ACE inhibitors/angiotensin receptor blockers and statins, through their beneficial effects on the cardiovascular system, have a positive impact on survival in very elderly hospitalized patients. Our data confirm the important role of such drugs even in this particular population with a mean age higher than 88 years, where scientific evidence is still scanty.
