People often think that atherosclerotic plaque in the coronary artery blockage narrow the extent of the more serious and more likely to suffer from myocardial infarction. Actually, this is not the case. Early lesions caused by stenosis is not heavy, but it is often the culprit of myocardial infarction. The study found that about 60% of myocardial infarction in patients with coronary artery stenosis less than 50%, while the degree of stenosis greater than 90% and only 10% of myocardial infarction patients.
Many patients with myocardial infarction would be very strange, “I have never angina, why suddenly a myocardial infarction?" Doctor explained, “early plaque in your coronary". Early plaque because of the small size, usually without any symptoms, but the plaque texture is soft and easy to break, medically known as vulnerable plaque. Emotional overworked factors, coronary blood flow acceleration, the coronary vasoconstriction spasm can lead to rupture of vulnerable plaque. Like the human skin and bleeding from the body will form a clot blocked wound, vulnerable plaque rupture will be the formation of a blood clot, and the size of the clot to determine the patient’s clinical manifestations. Small blood clots can cause blood vessels do not completely blocked, causing angina, a large blood clot will completely clog the blood vessels, causing myocardial infarction or sudden death.
Widely used interventional treatment significantly improved the quality of life in patients with coronary heart disease. Narrow coronary stent implantation, rapid recanalization can quickly improve the patient’s symptoms, and to achieve immediate results. It should be noted, interventional treatment does not solve all problems.
Vulnerable plaque in the coronary vascular tree distribution has disseminated, any – cases of atherosclerosis in patients with coronary angiography may show only somewhere coronary stenosis, but the overall look, once coronary angiography spots block formation, the entire coronary likely multiple atherosclerotic lesions exist. Coronary stent implantation can solve severe stenosis of the lesions, some mild lesions sometimes even coronary angiography are difficult to find, but often the culprit lesion of acute coronary syndrome, coronary artery overall protection is much more important than the treatment of localized plaque.
