What is the secret of longevity of coronary heart disease patients?

As we all know, coronary heart disease is the abbreviation of coronary atherosclerotic heart disease, which is mainly caused by atherosclerosis of coronary artery, the vessel supplying cardiac nutrients. The atherosclerotic plaques accumulate in the coronary artery, and the lumen is severely narrowed or even occluded, resulting in reduced myocardial blood flow and insufficient oxygen supply, thus affecting the normal operation of the heart, and producing a series of ischemic manifestations, such as chest tightness, shortness of breath, angina pectoris, myocardial infarction, and even sudden death.

Whether coronary heart disease patients can live a long life is a question concerned by patients and their families. However, to answer this question, we must start with the etiology and physiology of coronary heart disease.

Coronary heart disease is very harmful to human beings. As far as the world is concerned, it has become one of the most serious diseases threatening human health since this century. However, as long as it can be treated timely and effectively, it can still be cured and live a long life. This is because the coronary circulation has great potential. The main aspect of the potential ability is the existence of collateral circulation, which improves the blood supply of the heart wall.

So, what is collateral circulation? In the process of blood circulation, after the large vascular stem is blocked, the blood at its proximal end can bypass the obstruction through the collateral branch, and enter the distal end. This kind of blood is transported by the collateral instead of the main blood vessel to make the ischemic area get blood supply, which is called "collateral circulation". Most of the collateral vessels were dilated and thickened. Many diseases, such as atherosclerosis and rheumatism, can cause stenosis or occlusion of arterial lumen, thus establishing collateral circulation.

Why do you say that the longer the history of coronary heart disease, the longer you can live longer? The main reason is that the heart has its own protective ability. When the coronary artery is severely stenosed or even occluded, it will gradually play the role of collateral circulation. The wall of the heart is supplied by the left and right coronary arteries, and can be anastomosed between the ipsilateral coronary artery branches and between the two coronary artery branches. The diameter of anastomotic vessels was 20-350 μ M. The diameter and length increased with age and reached normal size at 18-20 years old. Once the coronary artery is blocked, the anastomotic vessels dilate and thicken, resulting in increased blood flow in the ischemic area.

The results show that collateral circulation can be established in a few days after acute coronary artery occlusion, but it will take several weeks to enrich the anastomotic vessels, and several months to make the anastomotic vessels play a full role. With the prolongation of the course of disease, the collateral circulation of the whole heart will be more abundant, the anastomotic vessels will become thicker, and the collateral circulation will be better. Therefore, the condition of coronary heart disease will be greatly improved.

This shows that although coronary heart disease is a serious threat to people's lives, but coronary heart disease must not be worried, but should be actively treated, give full play to the protective function of the heart itself, so as to prolong life.
