The diagnostic criteria of hypertrophic cardiomyopathy mainly include family genetic history, clinical symptoms (e.g. exertional dyspnea, chest pain, palpitations, etc.) and auxiliary examinations (including echocardiography suggesting that the thickness of the left ventricular wall is ≥15mm, electrocardiography suggesting T-wave inversion, changes in the electrical axis, and cardiac magnetic resonance suggesting that focal or patchy enhancement is found in the hypertrophied myocardium, etc.).
1. Medical history: Hypertrophic cardiomyopathy is a hereditary cardiomyopathy, and attention should be paid to family relatives with a history of cardiac hypertrophy, infarction at a young age, heart failure and other related diseases.
2. Clinical symptoms: patients often show exertional dyspnea, chest pain, palpitation, syncope, etc., and in severe cases, sudden cardiac death.
3. Auxiliary examination: echocardiography suggests that the thickness of the left ventricular wall is ≥15mm or ≥13mm in those with a clear family history of hypertrophic cardiomyopathy; more than 90% of patients have electrocardiographic changes, including T-wave inversion, changes in precordial voltage and electrical axis, and P-wave abnormality; and cardiac magnetic resonance shows that the hypertrophic cardiomyopathy has focal or patchy enhancement within the myocardium.
If the patient has the above manifestations, it is recommended to go to the hospital in time for consultation and active treatment after clarifying the cause of the disease.
