• The myocardial interstitium is a potential therapeutic target and a potential risk stratifier that can guide interventions.
• Clinical trials focusing on the myocardial interstitium are required to establish causality and improve patient outcomes.
• Cardiovascular magnetic resonance provides quantitative assessment of the myocardial interstitium and many other features of cardiovascular structure and function and thus can be used to stratify recruitment and to evaluate efficacy and mechanism.
The myocardial interstitium has emerged as a potential therapeutic target and as a biological entity to improve risk stratification and better guide existing interventions. Clinical trials focusing on the myocardial interstitium are required to establish causality and improve patient outcomes. This review will discuss issues around clinical trials targeting the myocardial interstitium, including antifibrotic therapies, efficacy outcome measurements, mechanistic outcome measurements and mediation analysis, sample size, trial duration, considerations for multicenter trials, stratifying trial recruitment according to the interstitium, and approaches to enrich recruitment, using examples of ongoing clinical trials.
