Whether coronary heart disease can live a long life can not be generalized, only manifested as stable angina patients have a better prognosis, most of them can live a long life, while the combination of diabetes or conduction block and other conditions of patients, survival time may be relatively short. Coronary artery disease is now a more common clinical cardiovascular disease, mainly due to coronary atherosclerosis. Whether patients with this condition can live a long life cannot be generalized, but needs to be judged in conjunction with the extent of the patient’s lesions and cardiac function. First of all, the prognosis for patients with only stable angina is relatively good, and most of them can live a long life after active treatment, as well as improvement of lifestyle habits and exercise of heart function. On the other hand, if the patient is combined with diabetes, or there are conditions such as conduction block or ventricular arrhythmia, which have a greater impact on cardiac function, the prognosis is relatively poor, and the patient’s survival time may be relatively shorter. However, patients can also prolong their survival by actively controlling their condition and slowing down its development through drug therapy. It is recommended that patients with coronary artery disease seek medical treatment as soon as possible, and follow the doctor’s instructions for regular checkups, improve lifestyle habits, and maintain a positive mindset.
