Sudden cardiac death has genetic characteristics, and common causes of sudden cardiac death mainly include the following aspects:

Coronary heart disease, angina, and myocardial infarction, especially acute myocardial infarction, often lead to sudden death in patients;

Secondly, long QT syndrome and Brugada syndrome are also common diseases causing sudden cardiac death and have genetic characteristics as hereditary arrhythmogenic disorders;

Thirdly, aortic dissection or pulmonary embolism. These diseases are usually not highly related to genetics but can also cause sudden cardiac death, hence sudden cardiac death is genetic.
