Hypertrophic cardiomyopathy 28mm is more serious and prompt treatment is recommended. Hypertrophic cardiomyopathy is mainly manifested as thickening of the ventricular septum and the left ventricular wall, the thickness of the ventricular septum or the left ventricular wall is generally measured to be ≥15mm, or ≥13mm in cases of a clear family history, and 28mm is much larger than the above values, and timely treatment is recommended. Hypertrophic cardiomyopathy, with the progression of the disease, will gradually appear outflow tract obstruction, which will lead to ineffective ejection of cardiac contraction, the patient is prone to fainting, or even sudden death. If the thickness of the posterior wall of the left ventricle or the septum reaches 28mm, there may be obstruction, and it is recommended to consult a doctor in time, and follow the doctor’s instructions to take oral beta-blockers and other drugs. The medication should be taken according to the doctor’s prescription, and if there is any discomfort, consult the doctor promptly.
