The causes of myocardial damage are primary heart disease and secondary non-cardiac diseases.
1. Primary heart disease is one of the most common causes of myocardial damage.
They include myocardial damage caused by coronary artery stenosis or blockage, such as acute myocardial infarction, chronic myocardial ischemia, etc.; myocardial damage caused by viral and bacterial infections, such as myocarditis, etc.; hypertrophic cardiomyopathy, dilated cardiomyopathy, cardiac valvular disease, mitochondrial myopathy and so on. All of the above diseases may lead to myocardial damage.
2. Secondary causes. Endocrine system diseases such as diabetes mellitus and thyroid, rheumatic system diseases such as systemic lupus erythematosus and dermatomyositis, tumors and blood system diseases can also lead to myocardial damage. Anti-rheumatic drugs such as hydroxychloroquine, cyclophosphamide, and antitumor drugs can also cause adverse reactions to myocardial injury.
When myocardial injury occurs, you should seek medical treatment in time, clarify the cause of the disease under the guidance of the doctor, and actively treat it.
