Extending the life chances of diabetic patients

A new study by Canadian scientists shows that coronary artery bypass surgery is a better option for clearing blocked coronary arteries than stenting if the patient has diabetes.

According to the results of a new study, conducted by doctors at St. Michael's Hospital in Toronto and published on September 12 in the journal Diabetes and Endocrinology, diabetic patients with blocked coronary arteries who undergo coronary artery bypass surgery will have a 33% higher chance of living 5 years than patients who have stents placed to clear the blocked artery.

In recent years, the number of coronary artery bypass surgeries has been decreasing as doctors often choose the less invasive coronary artery stenting procedure, which involves threading a catheter from the patient’s arm or thigh up to the heart, detecting narrowing or blockage in the artery, and then inserting a balloon or stent through the catheter to reopen the blockage. But the question remains whether stenting is a good option for diabetics.

Canadian researchers analyzed clinical data and found that in addition to living longer, diabetic patients who underwent coronary artery bypass surgery were 1.75 times less likely to have a fatal stroke in the five years following surgery than patients who received a stent. The increased risk of stroke was likely related to the fact that the patients had undergone surgery and were taking low-dose anticoagulants.

Dr. Gideon Cohen, a leading cardiovascular surgeon at Sunnybrook Health Sciences Centre in Toronto, said the study adds support to the idea that open surgery is a better surgical option for diabetic patients with blocked coronary arteries.

Coronary artery bypass surgery is an invasive procedure in which a blood vessel graft - a healthy artery or vein surgically removed from the patient's leg, arm or chest - is grafted to the site of a blockage.

The graft bypasses the blocked artery to supply oxygenated blood to the ischemic area of ​​the heart and restore blood flow to the heart. The increased blood flow improves symptoms, reduces the need for medication, and prolongs life.

Heart disease is the biggest killer of people with diabetes and people with diabetes account for 25% of people undergoing coronary artery surgery in Canada./.
