Myocardial disease is a common and frequently occurring disease in clinical practice, caused by various reasons leading to pathological changes in the myocardium. Common causes include viral infections, immune system disorders, and other factors, which can lead to degeneration, necrosis, fibrosis, and interstitial edema of the myocardium. This can cause heart failure, arrhythmias, and in severe cases, even death. Therefore, early diagnosis and timely treatment can save patients' lives and alleviate their suffering. It is necessary to consult with a psychiatrist, undergo relevant examinations under the guidance of a psychiatrist, make a clear diagnosis, and actively treat and rescue the patients.
