Myocardial hypertrophy on Asymmetry, ventricular cavity characterized by smaller, left ventricular filling blocked blood, diastolic compliance dropped to the basic pathological cardiac disease. Cause Hypertrophic cardiomyopathy may be autosomal dominant genetic related. About 1 / 3 of a clear family history. Catecholamine metabolic disorders. Hypertension, high-intensity campaign for the SIN factors. Pathological Hypertrophic cardiomyopathy major changes in the cardiac, in particular the left ventricle shape change. Characterized by inequality, such as thickening of the cardiac septum, also uniform myocardial hypertrophy (or) the type of apex hypertrophy. The characteristics of the Organization for myocardial hypertrophy, the specific shape, with disorder. Left ventricular septal myocardial cells in particular. Clinical performance [Symptoms] Hypertrophic cardiomyopathy clinical onset slow, multi-onset before the age of 30, about 1 / 3 with a family history of disease incidence history. Shortness of breath with the most common, after increased activity. Palpitation, such as chest pain. May have tired of the heart before the pain , Or when dizziness or syncope. Some may be no obvious symptoms or fewer symptoms, ultrasound and electrocardiogram showed that septum (or) non-symmetry of the left ventricular posterior wall thickening. Ventricular cavity narrow, narrow outflow tract. [Signs] Heart mild increase, and fourth heart sounds can be heard, the apex systolic murmur. Check ECG: The most common mast for left ventricular hypertrophy, ST-T changes, the pathological features of its Q-wave. Diagnosis The performance of similar clinical or ECG of patients with coronary heart disease, such as younger patients, the diagnosis of coronary heart disease is not based on other heart disease can not fully explain, they should consider the possibility of this disease. With ECG, echocardiography and cardiac catheterization to make the diagnosis. If positive family history (sudden death, heart increases, and so on) more conducive to the diagnosis. The disease through echocardiography, cardiovascular imaging and subendocardial myocardial biopsy can be heart disease and hypertension, coronary heart disease, congenital heart disease, aortic stenosis, such as differential phase. Treatment and prognosis The sudden death of the main reason for young people, more than the cause of death was heart failure in children, the advocates of ß-blockers and calcium channel blocker therapy. For patients with severe obstructive for intervention or surgical treatment.
