What is the Origin of Pathological Hypertrophy?

This term is foundational to pathology and cellular biology, serving to distinguish unhealthy tissue growth from physiological growth. The concept is particularly relevant in cardiovascular endocrinology, where chronic hypertension or hormonal excess can induce pathological cardiac hypertrophy. Understanding its distinction from physiological hypertrophy is critical for clinical diagnosis and intervention.

What is the Mechanism of Pathological Hypertrophy?

Chronic pathological stimuli, such as persistent pressure overload on the heart or excessive trophic hormone signaling in endocrine glands, activate specific intracellular signaling cascades, including the MAPK and calcineurin pathways. These signals promote increased protein synthesis and the expression of fetal genes, leading to an increase in cell size. Crucially, this growth is often disproportionate to the increase in vascular supply, leading to relative ischemia, fibrosis, and ultimately organ dysfunction.

Pathological Hypertrophy

Meaning

Pathological hypertrophy is the abnormal and detrimental enlargement of an organ or tissue resulting from an increase in the size of its constituent cells, typically triggered by chronic, excessive stress or disease states. Unlike the beneficial, adaptive hypertrophy seen with exercise, this form of cellular growth is maladaptive, often leading to structural remodeling and functional impairment of the affected organ. It represents a compensatory mechanism that ultimately fails to restore normal function.
