Heart disease caused by myocardial ischemia, hypoxia or necrosis due to arterial function change (spasm) is collectively referred to as coronary heart disease.
Coronary heart disease, also known as ischemic heart disease.
Coronary heart disease from mild to severe includes stable angina pectoris, angina pectoris with normal coronary artery (such as syndrome X), asymptomatic myocardial ischemia and ischemic heart failure (ischemic cardiomyopathy). Unstable angina pectoris (UA), non-ST-segment elevation myocardial infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI), including sudden death of coronary heart disease; People with different course of disease have different risk factors and different relative life expectancy, so it is hard to say how long it is, but strictly according to the diagnosis and treatment in regular hospitals, life expectancy can definitely be extended.
