WebJul 6, 2024 · Death of adult cardiac myocytes and supportive tissues resulting from cardiovascular diseases such as myocardial infarction is the proximal driver of pathological ventricular remodeling that often culminates in heart failure. Unfortunately, no currently available therapeutic barring heart transplant … Hypertrophic cardiomyopathy (HCM) is a genetic condition in which the cardiomyocytes are not arranged in a coordinated fashion and are instead disorganized. HCM can interrupt blood flow out of the ventricles, cause arrhythmias (abnormal electrical rhythms), or lead to congestive heart failure. See more Dilated cardiomyopathy causes the cardiac muscle tissue of the left ventricle to stretch and the heart’s chambers to dilate. See more Restrictive cardiomyopathy (RCM) refers to when the walls of the ventricles become stiff. When this happens, the ventricles cannot relax enough to fill with an adequate amount of … See more Transthyretin amyloid cardiomyopathy (ATTR-CM) develops when amyloid proteins collect and form deposits in the walls of the left ventricle. The amyloid deposits cause the ventricle’s walls to stiffen, which … See more This rare form of cardiomyopathy causes fatty infiltration in cardiac muscle tissue in the right ventricle. See more
