Effect of obesity on left ventricular mass and systolic function in patients with asymptomatic aortic stenosis (a Simvastatin Ezetimibe in Aortic Stenosis [SEAS] substudy). Thirty-four percent of patients with ASH had combined ASH and LV hypertrophy (asymmetric LV hypertrophy). The thickened heart muscle makes it harder for the heart to pump blood and makes the heart prone to a rare but serious rhythm dysfunction.

The left ventricle is the heart's main pumping chamber. However, in a small number of people with HCM, the thickened heart muscle can cause shortness of breath, chest pain or changes in the heart's electrical system, resulting in life-threatening irregular heart rhythms (arrhythmias) or sudden death. Approximately 3%-5% of affected individuals have more than one sarcomere gene variant (either biallelic variants in 1 gene or heterozygous variants in >1 gene) although fewer than 1% will have more than one pathogenic or likely pathogenic variant 17.
