In subjects with a number of risk factors such as hypertension, smoking, dyslipidemia, diabetes that contribute to lớn vascular damage over time. It is these disorders that make the walls of blood vessels more susceptible khổng lồ cholesterol molecules khổng lồ be deposited and adhered to.

Where atherosclerotic plaque attaches to the inflamed vessel wall, at some point this plaque is peeled & broken, promoting the formation of a blood clot that blocks the blood vessel lumen. When the lumen is blocked, the posterior myocardium is not supplied with blood, resulting in necrosis & death of the myocardium, causing myocardial infarction.

Coronary bypass surgery (CABG): The patient was anesthetized & the surgery was carried out in the operating room at the Department of Cardiac Surgery. Vascular segments taken from other places in the body toàn thân are used khổng lồ bridge the anterior và posterior occlusion, allowing blood to follow the graft to feed the underlying heart muscle.
