Heart disease is very common in diabetes.

Coronary Heart Disease or Heart Attack:
High glucose can lead to narrowing in the coronary arteries which supply blood to the heart. When such a major blood vessel is blocked, blood flow to the heart is stopped, causing heart attack. Generally there is heaviness or pain in the chest pain during heart attack, but diabetic patients can have a fatal heart attack without the warning of chest pain due to diabetic neuropathic changes.

Recommended Tests
ECG (Electrocardiography), Treadmill Test, Echocardiography and coronary angiography.

Prevention
Diabetes Control, cholesterol control and weight control and maintenance of normal blood pressure goes a long way in preventing heart disease.
