Antihypertensive drug class in combination with lipid lowering treatment for primary prevention of cardiovascular disease in the elderly.
2022
Abstract Background Antihypertensives and lipid-lowering therapy (LLT) are often used concurrently. Objectives To determine whether there was a difference in clinical outcomes when older patients with LLT were prescribed angiotensin-converting-enzyme-inhibitors (ACE-Is) compared with diuretics. Methods This analysis included 648 LLT older users free of cardiovascular disease (CVD) from a trial comparing ACE-I versus diuretic-based therapy. Comparisons were made between LLT+ACE-I (n = 335) and LLT+diuretic groups (n = 313) using multivariable Cox proportional-hazard models. Primary endpoints were all-cause and CVD mortality (in-trial [4.1-year]+post-trial [6.9-year]) and secondary endpoints (in-trial) were the composite of all-cause mortality and first CVD events and its components, CVD mortality and incident diabetes. Results There were no significant differences between the two groups for the primary endpoints over the in-trial plus post-trial follow-up, nor was there a difference for any secondary outcomes over the in-trial follow-up. Conclusions The LLT+ACE-I and LLT+diuretic combinations showed similar effects in CVD-free older individuals. Randomised trials are needed to provide conclusive evidence.
