Cardiovascular disease is the first killer endangering human life and health, and coronary heart disease is one of the killers.
When you are young, the coronary artery is soft and elastic, and it continuously delivers blood to the heart, making the heart full of vitality. However, with the increase of age and some external factors, such as high fat and cholesterol in diet, and the occurrence of chronic diseases such as diabetes, hypertension and hyperlipidemia, this blood vessel may harden or spasm due to some "dirt" deposited on the blood vessel wall. If these conditions continue to develop and are not treated in time, coronary artery stenosis or even obstruction and thrombosis are easy to occur.
The most terrible thing is that once the coronary artery is completely occluded, the nutritional pathway of the heart is also interrupted. If there are no nutrients in the heart, myocardial ischemia and abnormal activities can occur in a very short time, and some people will have angina pectoris and myocardial infarction, and even more serious will lead to cardiac arrest and death.
