- Description: Among 610 heart attack survivors enrolled in cardiac rehabilitation, the 236 with diabetes died more often over five years and faced a substantially higher risk of sudden cardiac death than those without, even when they showed no clinical sign of residual myocardial ischemia.

Monday Dec 3, 2012 (foodconsumer.org) -- Diabetes mellitus (DM) is a well known risk factor for coronary heart disease disease, which is also known as coronary heart disease, a major form of heart disease. Diabetes mellitus is known to be associated with cardiovascular disease.

The current study was intended to examine the association between diabetes mellitus and risk of sudden cardiac death in patients who survived myocardial infarction.

The study involved 610 patients who had experienced myocardial infarction and were enrolled in a cardiac rehabilitation program with negative exercise stress test. 

A total of 236 patients had diabetes mellitus at baseline. During a 5-year follow-up, 28.4% patients with diabetes mellitus died compared to 20.2% of those who had diabetes mellitus.

It was also found that patients with diabetes mellitus were at a 82% increased risk for sudden cardiac death. And the risk was 114% higher among patients with diabetes mellitus, compared to those without.

Having diabetes mellitus, left ventricular ejection fraction less than 30%, and New York Heart Association functional class greater than II were 90, 260 and 320 percent more likely to have sudden cardiac death, respectively, compared with those who did not have these conditions.

"Among patients with DM, the 5-year sudden cardiac death rate did not differ significantly among those with LVEF ≤30%, LVEF 31-50%, or LVEF >50% (8.8 vs. 7.8 vs. 6.8%, respectively; P = 0.83)," the researchers wrote.

The researchers concluded "Post-MI (myocardial infarction) patients with DM (diabetes mellitus), even in the absence of residual myocardial ischemia clinically, were at higher risk of sudden cardiac death than their non-DM counterparts."
