In diabetic patients, high blood sugar levels are known to slowly damage blood vessels, especially those in the heart and brain. According to an alarming study which appeared in the Journal of Circulation, a diabetic is six times more likely to develop heart failure and four times more likely to have a heart attack.

They tested samples from more than 9,000 participants in the Atherosclerosis Risk in Communities Study (ARIC) at two time points, six years apart. Those with diabetes were two and a half times more likely to have elevated troponin levels than those who weren't. Then researchers looked at 14 years of follow-up data from ARIC and found that diabetics with elevated troponin were six times more likely to develop heart failure and four times more likely to have a heart attack.
