Coronary artery stenosis is a serious disease with a high mortality rate. To avoid the risk of death due to stenosis, early coronary intervention is required. Coronary stenting is an interventional method to improve coronary artery stenosis.
1. What is coronary artery stenosis?
The coronary arteries are a system of arteries that supply blood to the heart muscle. Coronary artery stenosis is caused by the deposition of cholesterol on the artery wall, causing plaque formation and reducing the amount of blood supply to the heart muscle.
2. Causes of coronary artery stenosis
Age: With age, the risk of coronary artery disease increases. Family history of cardiovascular events at a young age (male < 55 years old, female < 65 years old). Dyslipidemia: Increased cholesterol in the blood. Smoking too much, drinking too much alcohol. Systemic diseases: Hypertension, diabetes, obesity...
3. Symptoms of coronary artery stenosis
Some factors that directly affect coronary artery stenosis are strenuous labor, weather changes... the patient appears chest pain behind the sternum, which can spread to the shoulder and fingers, time if it is a stroke. Stable angina lasts for a few minutes, while unstable angina can last more than 30 minutes.
Myocardial infarction occurs when almost the entire coronary artery narrows, the patient has severe chest pain if not detected and treated in time, causing a very high risk of death.
4. Why does coronary artery stenosis need early intervention?
Coronary artery stenosis is a common disease in the elderly and is a very dangerous disease with a high risk of death. Because atherosclerotic plaque causes narrowing of the artery, there is not enough blood supply to the heart muscle, leading to myocardial necrosis and death for patients.
Coronary stenting is a fast percutaneous coronary intervention technique with fast recovery time to help improve the ischemia of the myocardium.
In the case of patients with arterial stenosis of more than 70%, it is necessary to intervene early coronary stenting to avoid the risk of myocardial infarction. In addition, cases of stable angina that cannot be controlled despite optimal medical treatment, unstable angina... are also indications for coronary stenting.
