In the November 26, 2024 issue of JACC, Dr. Valentin Fuster highlights four pivotal studies in cardiovascular research. The first explores the independent roles of social determinants of health and polygenic risk scores in coronary heart disease, while the second assesses the impact of recurrent rejection on pediatric heart transplant outcomes. The third paper examines the effects of CSL 112 infusions on reducing ischemic events post-myocardial infarction, and the fourth investigates the interplay between pulmonary hypertension and heart failure with preserved ejection fraction. Each study advances our understanding of cardiovascular risk, treatment, and outcomes.
