Now there is an added incentive for all the obese people around the world to lose weight. A recent study conducted by the University of Alberta researchers at the Faculty of Rehabilitation Medicine found that patients with a BMI of over 30 had higher risks of suffering from post-operative infection after a successful heart bypass surgery. The surgery is essential for patients, who have showed no positive changes with medication or therapies, suffering from clogging of arteries. Arteries are responsible for the free flow of oxygen rich blood to various parts of the body, essentially the heart. With aging and lifestyle issues, the inner walls of the artery form deposits of plaque (fat). This blocks the path for blood flow and as a result the body is deprived of sufficient quantity of blood.
According to some of the best surgeons for heart bypass surgery, this is a very logical outcome as the immune system of an obese patient is always under immense stress. The chronic inflammation suffered by the obese makes their immune system fail against infections. This is largely caused by physical inactivity, lack of balanced diet and lifestyle issues which are commonly found among the obese individuals. All these factors lead to poor health and the immune system has to work overtime, thus it gets weak over a span of time.
Another interesting finding was published in the Canadian Journal of Cardiology. This study found that more than 88% of obese patients with heart bypass surgery needs, underwent Percutaneous Coronary Intervention (PCI) while 55% of such patients received Coronary Artery Bypass Grafting (CABG). CABG mostly involves open heart surgery, PCI on the other hand is a non-surgical procedure where a stent is placed to stop the heart arteries re-narrowing in the future. What this points to is: the surgeon would not risk the post-operative complications if you are an obese patient, and suggest the PCI (even when CABG would be a better alternative).
