What symptoms can myocardial ischemia necrosis cause?

The symptoms of myocardial ischemia and necrosis mainly include precordial discomfort, arrhythmia, cardiac insufficiency, etc.

1. Precordial discomfort

Due to myocardial ischemia and necrosis, some acidic metabolites and inflammatory substances are secreted. When the surrounding tissues are stimulated, they cause vasospasm, which will cause symptoms of precordial discomfort.

2. Arrhythmia

Due to myocardial ischemia and necrosis, the cardiac electrical conduction system is abnormal, thus affecting the frequency and rhythm of heart beats.

3. Cardiac insufficiency

Due to myocardial ischemia and necrosis, cardiac vascular regulation is abnormal, thus affecting the basic function of the heart. Symptoms of cardiac insufficiency will occur.
