Risk factors for hypertrophic cardiomyopathy

Major risk factors for hypertrophic cardiomyopathy are:
▪ Cardiac arrest (ventricular fibrillation)
▪ Spontaneous sustained ventricular tachycardia
▪ Family history of sudden death
▪ Minor risk factors
▪ Unexplained syncope
▪ Left ventricualr wall thickness>30mm
▪ Abnormal blood pressure on exercise(failure to rise from baseline by 25mmHg)
▪ Non sustained Ventricular tachycardia
▪ Left ventricular outflow obstruction
▪ Microvascular obstruction
▪ High risk genetic defect.
