Mild myocardial ischemia does not usually cause sudden death, and with severe myocardial ischemia, there is a risk of sudden death.
In general, mild myocardial ischemia has no obvious discomfort such as chest tightness or palpitations, and may only be indicated by an electrocardiogram. Severe myocardial ischemia, which has the risk of causing heart block, heart dysfunction and myocardial infarction, may lead to sudden death.
1. Heart block: may lead to sudden cardiac arrest.
2. Cardiac dysfunction: Malignant arrhythmia, such as ventricular fibrillation, affects blood pressure and heart rate, leading to sudden death.
3. Myocardial infarction: This can lead to sudden death.
If myocardial ischemia occurs, it is necessary to actively seek medical treatment, improve electrocardiogram, coronary CTA, coronary angiography and other related examinations, and if necessary, follow the doctor’s instructions for oral aspirin and other secondary prevention of cerebrovascular disease medication.
