In many cases, hypertrophic cardiomyopathy is caused by a mutation in one of the genes that make up the cardiac sarcomere, and only a single copy of a defective gene is needed for the disorder to develop (autosomal dominant inheritance). In these cases, its called hypertrophic nonobstructive cardiomyopathy. Dearani JA, et al. Try to avoid drinking alcohol, drinks containing caffeine (tea, coffee, and cola) or drinks high in sugar.

Your heart beats faster and pumps harder, and may circulate two to four times as much blood each minute as it does on a cool day. Hypertrophic cardiomyopathy (HCM) is a heritable, autosomal dominant disorder of structural abnormalities confined to the heart. the application of contemporary cardiovascular treatments and management strategies to hypertrophic cardiomyopathy (hcm) over the last decade have altered the natural history and course of this genetic heart disease, now providing the vast majority of at-risk hcm patients the reasonable expectation for extended (if not normal) longevity and The thickening can occur anywhere in the left lower heart chamber (left ventricle). Eat Healthfully Eating a healthy diet can improve heart health. It is commonly asymmetrical with the most severe hypertrophy involving the basal interventricular septum.

In most people, fatigue is caused by lifestyle problems like lack of exercise, excess physical activity, alcohol or drug use, lack of sleep, or unhealthy diets. It usually affects the left ventricle, the chamber of the heart responsible for pumping oxygenated blood to the body. This results in the heart being less able to pump blood effectively and also may cause electrical conduction problems. Your healthcare provider may consider a myectomy if medications arent working. The thickened septum may cause a narrowing that can block or reduce the blood flow from the left ventricle to the aorta a condition called outflow tract obstruction. This procedure, also called septal ablation, is reserved for people who cant have a septal myectomy. Fatigue is one of the most common symptoms of HCM. Primary prevention with an ICD is reasonable for patients with severe hypertrophy (>30mm), family history of sudden death in a first degree relative, recent unexplained syncope, or "burnt-out" HCM (LVEF < 50%).2,6,7 The presence of non-sustained ventricular tachycardia on 24-hour Holter or abnormal blood pressure response to exercise, when added to other risk factors, also supports primary prevention ICD.14 Other risk factors that may influence the decision to place an ICD for primary prevention include marked late-gadolinium enhancement on magnetic resonance imaging (MRI) (>15%), the presence of an apical aneurysm, and some genetic mutations present in families with high prevalence of sudden cardiac death.3,6,7,15-17 Secondary prevention with ICD placement in those surviving SCD or with sustained ventricular tachycardia (VT) is universally recommended.6 In the case of syncope, a thorough evaluation for provoked obstruction is first required to avoid ICD implantation for syncope related to LVOTO rather than ventricular arrhythmias.7 Periodic reassessment of risk factors is recommended as part of ongoing follow up, with more frequent testing reserved for younger patients and those with borderline risk factors. Kirklin JW, et al. It can cause: This occurs most commonly at your septum. The thickened walls may become stiff and this can reduce the amount of blood taken in and pumped out to the body with each heartbeat.
