Heart Surgery in Diabetic Patients

Diabetes mellitus (DM) is closely linked with ischemic heart disease (IHD). This metabolic disorder accelerates the development of coronary atherosclerosis, and its frequency and severity often increase with poor glycaemic control. As a result, coronary artery disease remains the leading cause of death among diabetic patients. Serious cardiac events such as acute coronary syndrome and acute myocardial infarction (AMI) occur nearly three times more often in people with diabetes than in non-diabetics. Diabetic patients often present with more extensive and severe coronary artery disease, involving multiple vessels and complex lesions. In addition, they commonly have associated risk factors such as high blood pressure, high cholesterol, obesity, and long-term damage to blood vessels caused by persistently elevated blood sugar levels. Many patients still need interventional or surgical treatment, even though lifestyle modifications and stringent blood glucose and cholesterol control can halt the progression of plaque. Why surgery is Preferred in diabetic patients Studies have consistently shown that coronary artery bypass grafting (CABG) offers better long-term outcomes than other revascularisation strategies, especially in diabetic patients with multivessel disease. CABG significantly reduces the risk of restenosis, a common problem after coronary stenting. In fact, diabetic patients with multivessel coronary artery disease treated with CABG have been shown to survive nearly three years longer than those treated with alternative methods. Given these benefits, the proportion of patients with diabetes undergoing CABG continues to rise worldwide. However, diabetes also increases surgical risks. High blood sugar during surgery is associated with poorer recovery, higher infection rates, and increased mortality. Therefore, careful intraoperative blood sugar monitoring and insulin therapy are standard practices during heart surgery. Surgical challenges unique to diabetic patients Diabetes negatively affects wound healing due to impaired fibroblast function and persistent hyperglycaemia. Postoperative complications such as surgical site infections, pneumonia, urinary tract infections, and delayed wound healing are more common. Diabetic patients may spend 30–50% longer in hospital following surgery compared to non-diabetic patients of the same age. Traditional heart bypass surgery involves opening the chest and using saphenous veins from the legs to bypass blocked arteries. Unfortunately, these leg veins often block within 10 years, necessitating redo surgeries that carry higher risks—especially in diabetic individuals. A breakthrough in cardiac surgery At Aster RV Hospital, under the expertise of Dr. Divakar Bhat, one of the Best Heart Surgeons in Bangalore, advanced cardiac surgical techniques are transforming outcomes for high-risk patients, especially those with diabetes. To overcome the challenges associated with conventional open-heart surgery, a highly effective minimally invasive cardiac procedure is practiced—offering exceptional benefits for diabetic patients. This innovative approach uses a small two-inch left mini-thoracotomy incision, avoiding complete chest splitting. Bilateral internal thoracic arteries (BITA) are harvested under direct vision on a beating heart, without robotic assistance. Using an off-pump technique, total arterial revascularisation is achieved with the left and right internal thoracic arteries (LITA–RITA) configured as a Y composite graft. Unlike leg vein grafts, mammary arteries can remain functional for over 30 years, ensuring superior long-term results. This makes the procedure a preferred option for patients seeking the Best Open Heart Surgery in Bangalore with durable outcomes. The minimally invasive nature of this surgery significantly reduces infection risk, enhances wound healing, and minimizes complications common in traditional procedures. Most patients are discharged within three days and resume normal activities in about 10 days, making it an ideal choice for those looking for the Best Treatment for Heart Related Problems in Bangalore. With comprehensive cardiac care delivered by the Best Cardiologist in Bangalore and an experienced surgical team, Aster RV Hospital continues to set benchmarks in advanced heart treatment and patient recovery. Managing diabetes to protect the heart India is witnessing a rapid rise in both diabetes and heart disease, making prevention and early intervention critical. Keeping diabetes under control through a disciplined lifestyle, balanced diet, regular exercise, and proper medication under medical supervision can greatly reduce the risk of heart disease. At Aster RV Hospital, under the expertise of Dr. Divakar Bhat, patients receive advanced, personalised cardiac care. With innovative techniques and a patient-centric approach, even diabetic patients can enjoy longer, healthier lives after heart surgery.
