Coronary artery disease had spread in a larger number among the people worldwide. According to statistics, about 50 percent of the patients suffered from left main coronary artery stenosis. Many of the people possess the risk of the heart failure due to blockage in vessels that mainly occurs at the left main coronary artery. This could only be protected if the patent bypasses graft or the collateral flow to the left anterior be preferred. Researches were done to find out an effective treatment procedure and what comes out of it before revascularization was the prognosis available for patients. Later on, coronary artery bypass graft surgery (CABG) was considered as a better treatment for treating coronary artery that serves with positive outcomes.
During the left main coronary artery stenosis those patients who are at high risk of CABG were kept away from the Percutaneous Coronary Intervention. Most of the people who are suffered from left main coronary artery were given an urgent bypass grafting. The patients who undergo through the bypass grafting were rarely having cardiac problems. Those patients who face such problems need to be giving emergency bypass grafting. Left coronary artery is a serious disease that needs to be treated soon. Those patients who have Left Main Coronary Artery Stenosis ( LMCA ) have to undergo through the severe pain. They have to deal with high complications that occur during their treatment. To prevent LMCA angioplasty may be done that would help in improving the patient condition.
The coronary artery bypass grafting has been done in the case of left main coronary artery stenosis by considering as an urgent treatment process given to the patient at such time. However, depending on the patient health and logical constraints, the CABG sometimes performed less urgently. This is due to reason that the doctors need to identify the risk for the occurence of Coronary Artery Stenosis disease. As all the patients were not given the same treatment, they were at first divided into groups as eventful waiting group and uneventful waiting group. In the first group those patients who have experienced cardiac events were kept, whereas in the second group patients who have not experienced the cardiac events were kept. The event includes the myocardial infarction or ischemia that could be due to enzyme activity, congestive heart failure or symptomatic ventricular arrhythmia.
Studies have shown that in a family if two or more than two members have heart disease and if one has a left main coronary artery stenosis disease, then the second member would have three times more risk to suffer from the same. It is important to predict the symptoms beforehand to prevent this disease at an early stage. Studies have shown that the patient suffering from coronary heart disease could get a good result from the medical therapy and coronary artery bypass grafting when it has been given carrying with revascularization. Studies have also shown that the survival rates were considerably increased after patients were revascilarised with CABG and PCI. The PCI gets associated with a high rate of repeated revascularization.
