Rethinking atherosclerotic cardiovascular disease prevention in the era of expanding therapies: could plaque stabilization reduce the need for lifelong treatments and polypharmacy?

Purpose of review: This review examines current evidence on pharmacologically induced plaque stabilization in the context of a growing range of new therapies. It explores the potential for a paradigm shift in atherosclerotic cardiovascular disease (ASCVD) prevention, where treatments may not need to be lifelong to achieve lasting benefits.

Recent findings: Since 2015, over 14 novel therapies have been introduced, each shown to reduce ASCVD risk when added to standard care with statins and aspirin. More than 80% of ischemic heart disease patients are now eligible for one or more of these treatments, increasing the risk of polypharmacy, treatment burden, and adverse side effects. As more therapies become available, this challenge is expected to grow. Many of these treatments have demonstrated plaque regression and stabilization, as evidenced by both intravascular ultrasound and computed tomography angiography, which likely explains much of their efficacy.

Summary: The increasing number of novel therapies presents challenges in preventing ASCVD without leading to lifelong polypharmacy and increased patient burden. Since many of these drugs act through plaque stabilization, a new approach may be feasible - using these treatments for shorter durations to induce plaque regression, followed by less intensive maintenance therapies to preserve stability. This approach warrants further investigation in future studies.
