A new study conducted by researchers from the University of Iowa on mice showed that the increased risk of death with heart attacks in diabetic patients could be due to activation of a vital heart enzyme which leads to the death of pacemaker cells and an irregular heart rate.
The death rates of diabetic adults with heart diseases are 2 to 4 times higher than adults without diabetes. The primary cause of death in diabetic patients in US population is myocardial infraction (heart attack).
Truncus arteriosus is actually a heart defect which leads to severe problems the circulatory system. It is a rare type of heart disease, and it is congenital in which a large blood vessel leads out of the left and right ventricles, instead of the normal two blood vessels, that is, one pulmonary artery and aorta. The two lower chambers of the heart also miss a portion of the wall which separates them.
