Hypertrophic cardiomyopathy (HCM) is associated with thickening of the heart muscle, most commonly at the septum between the ventricles, below the aortic valve. Hydralazine may rarely cause blood dyscrasias at recommended dosages. 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 and can lead normal lives with no significant problems. Hydralazine hydrochloride can cause tachycardia and hypotension potentially leading to myocardial ischemia and angina, particularly in patients with hypertrophic cardiomyopathy. Often, only one part of the heart is thicker than the other parts. •In hypertrophic cardiomyopathy patients without significant LV hypertrophy, in addition to basal septal thickness, anterior MV length, abnormal chordal attachment, and bifid PM mobility are associated with LVOT obstruction. 2011 ACCF/AHA Guideline for the Diagnosis and Treatment of Hypertrophic Cardiomyopathy : A Report of the American College of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines .
