What is the Origin of Cardiac Remodeling?

The term combines the Greek word kardia, meaning "heart," with the English word remodeling, which implies a change in structure or form. The concept emerged in cardiology to describe the dynamic, post-injury adaptation of the ventricle, moving beyond simple hypertrophy to encompass a comprehensive change in myocardial architecture. This understanding highlights the heart's capacity for structural adaptation, both beneficial and detrimental, in response to chronic stimuli.

What is the Mechanism of Cardiac Remodeling?

The process is mediated by neurohormonal activation, local mechanical stress, and inflammatory signaling pathways that regulate the synthesis and degradation of the extracellular matrix and influence cardiomyocyte survival and growth. Hormones, particularly aldosterone, angiotensin II, and sex steroids, exert direct and indirect effects on these signaling cascades, modulating fibroblast activity and myocyte size. Pathological remodeling results from a sustained maladaptive response, leading to ventricular dilation, wall thinning, and a progressive decline in systolic and diastolic function.

Cardiac Remodeling

Meaning

Cardiac remodeling is a complex biological process involving molecular, cellular, and interstitial changes that lead to alterations in the size, shape, and function of the heart muscle, often in response to pathological stress. This structural reorganization, typically triggered by conditions like hypertension, myocardial infarction, or chronic hormonal imbalance, can initially be compensatory but frequently progresses to ventricular dysfunction and heart failure. In hormonal health, the long-term effects of deficiencies or excesses, particularly of thyroid or sex hormones, can significantly influence this pathological progression.
