Diabetic people have a high risk at an early age because abnormal blood sugar levels silently induce damage to the blood vessels and nerves and thus develop heart disease, which silently leads to a silent heart attack. Furthermore, a person with diabetes has huge risk of developing complications related to heart if he or she has a family history of diabetes, high blood pressure with other risk factors like smoking, unhealthy diet and high cholesterol levels. Similarly, in obese individuals with diabetes who have high lipid and high blood pressure – atherosclerosis at a very young age may cause heart disease and heart attacks.

How are the results after angioplasty or bypass surgery in diabetic people?

In individuals with diabetes the main cause for concern is that their heart disease is a silent affair as it may go undetected owing to lack of symptoms. Their heart disease may become diffused – which means they have multiple blocks in their arteries. Such a condition may lead to heart failure; in such cases, the complications associated with the bypass surgery or angioplasty are high as surgical and interventional procedures cannot be efficiently performed. Therefore, recovery is poor and complications are very high in cases with diffused heart disease.

What is the action plan to reduce the risk?

Lifestyle changes including losing weight, exercise, healthy diet, quitting smoking (if you smoke) that you do to control your diabetes are actually good for your heart as well. Owing to the several factors that contribute to the increasing incidences of heart -related deaths in diabetic patients, diabetic people need frequent heart checkups even if they don’t have any heart-disease-related symptoms.
