Hypertrophic obstructive cardiomyopathy is a type of cardiomyopathy with the typical symptom of asymmetric hypertrophy of the myocardium. It is usually diagnosed by echocardiography, and common treatments include medication, chemical ablation therapy, and surgery. Hypertrophic obstructive cardiomyopathy is a disease in which asymmetric hypertrophy of the myocardium is accompanied by a narrowing of the ventricular chambers, resulting in impaired cardiac function due to restricted ventricular filling. Most patients with hypertrophic obstructive cardiomyopathy have a family history of the disease, due to inherited genetic mutations. Typical symptoms of patients with hypertrophic obstructive cardiomyopathy are dyspnea, pain in the precordial region, dizziness, fainting, weakness, palpitations, and heart failure. The diagnosis can be confirmed by echocardiography, looking at the patient’s body cardiac catheterization appears to do ventricular outflow tract pressure, combined with the presence of typical symptoms and the patient’s family history. Hypertrophic obstructive cardiomyopathy should seek medical attention in time to avoid delays.
