WebHypertrophic cardiomyopathy is a congenital or acquired disorder characterized by marked ventricular hypertrophy with diastolic dysfunction (eg, due to valvular aortic stenosis, coarctation of the aorta, systemic hypertension). Symptoms include dyspnea, chest pain, syncope, and sudden death. WebHypertrophy arises due to an increase in the proliferation of cellular proteins. In particular, increased cellular proteins in cardiac myocytes can occur due to various stimuli, such as mechanical stretch receptors that detect increased workload, increased growth factors, and the presence of agonists.
