Implication

Supports vigilance for maladaptive remodeling after cardiac injury; leaves open optimal targets to interrupt progression in trials.

Key Points

Summarize the cellular and physiological mechanisms governing ventricular remodeling after cardiac injury and identify how initial compensatory responses transition into clinical heart failure.
Evaluated experimental animal models and clinical investigations of left ventricular remodeling following cardiac injury.
Assessed the impacts of neurohormonal signaling, cytokine release, mechanical loading, and therapeutic interventions including angiotensin-converting enzyme inhibitors.
Myocardial injury stimulates cytokine release, neurohormonal activation, and mechanical loading alterations that induce myocyte remodeling, interstitial growth, and chamber dilatation.
Early compensatory adaptations progressively shift into maladaptive processes that drive cardiomegaly and severe congestive heart failure.
Peripheral vascular abnormalities occur alongside myocardial changes, marked by reduced vasodilator reserve and impaired endothelial-dependent relaxation to acetylcholine.
