What is the Origin of Ventricular Remodeling?

This is a core concept in modern cardiology, emerging from the study of the heart's response to conditions like myocardial infarction and chronic hypertension. The term "remodeling" highlights the dynamic, structural reorganization of the ventricular myocardium. Clinical strategies are now heavily focused on pharmacological and device-based interventions to prevent or reverse this process.

What is the Mechanism of Ventricular Remodeling?

The mechanism is complex, involving the chronic activation of the renin-angiotensin-aldosterone system (RAAS) and the sympathetic nervous system, alongside increased mechanical wall stress. These factors stimulate the proliferation and activation of cardiac fibroblasts, leading to excessive deposition of collagen and fibrosis in the extracellular matrix. Simultaneously, individual heart muscle cells undergo hypertrophy or apoptosis, resulting in a less efficient, dilated ventricular chamber.

Ventricular Remodeling

Meaning

Ventricular Remodeling is a pathological process involving progressive, maladaptive changes in the size, shape, mass, and function of the cardiac ventricles, typically initiated by myocardial injury or chronic pressure/volume overload. This structural alteration is a critical determinant and predictor of the transition from asymptomatic cardiac damage to overt heart failure. Hormonal and neurohumoral factors are significant drivers of this continuous, detrimental reorganization.
