Global Variations in Patient Populations and Outcomes in Heart Failure Clinical Trials.

PURPOSE OF REVIEW: Heart failure is a global pandemic and there has been a growing effort to enroll patients from different geographical regions in randomized controlled trials. In this review, we examined regional variation in both patient characteristics and outcomes among several of the most recent global heart failure trials RECENT FINDINGS: Retrospective analyses of global heart failure trials have identified marked variations in both baseline characteristics and management of heart failure by region of enrollment. In some trials, this variation has been significant enough to cause differential treatment effects. We summarized key heterogeneity observed in global heart failure clinical trials. Differences in both patient population and organization of these trials abroad pose an important challenge in making interpretations and country-level decisions. As such, we encourage a concerted effort to account for these differences in future research.
