Focal myocyte hypertrophy
Hypertrophic cardiomyopathy (HCM) is a disease in which the heart muscle becomes thickened (hypertrophied). The thickened heart muscle can make it harder for the heart to pump blood. Hypertrophic cardiomyopathy often goes undiagnosed because many people with the disease have few, if any, symptoms. … See more Signs and symptoms of hypertrophic cardiomyopathy might include one or more of the following: 1. Chest pain, especially during exercise 2. Fainting, especially during or just after … See more Hypertrophic cardiomyopathy is usually caused by changes in genes (gene mutations) that cause the heart muscle to thicken.

People with one parent with hypertrophic cardiomyopathy have … See more WebNumerous studies demonstrated increased expression of extracellular matrix (ECM) proteins and activation of focal adhesion (FA) signaling pathways in models of pressure overload-induced cardiac hypertrophy. However, little is known about FA signaling in response to volume overload where cardiac hypertrophy is associated with ECM loss.
