There is no targeted treatment for myocardial densification insufficiency, which is mainly for heart failure and arrhythmia, including drug antihypertensive treatment and surgical transplantation treatment. 1. Drug therapy: Due to individual differences, it is necessary to choose appropriate drugs under the guidance of the doctor. For the treatment of heart failure, angiotensin-converting enzyme inhibitors such as captopril can effectively lower blood pressure and improve cardiac remodeling, and antiarrhythmic drugs such as lidocaine can be used for patients with arrhythmia. 2. Surgical treatment: heart failure patients can choose cardiac synchronization therapy to improve the pumping function of the heart, for arrhythmia patients can choose catheter ablation. If the heart disease is serious, heart transplantation can be chosen. When the patient is not feeling well, he should go to the hospital immediately.
