Heart Attack Death Rate Higher in Diabetics: Study

Heart Attack Death Rate Higher in Diabetics: Study

According to Australasian Medical Journal (AMJ) Diabetes is fast gaining the status of a potential epidemic in India with more than 62 million diabetic individuals currently diagnosed with the disease. Diabetes also being a risk factor for heart diseases  is going to increase the mortality rate significantly. It is observed that cardiovascular disease leading to heart attack or stroke is by far the leading cause of death in both men and women with diabetes.

Research Study: The study included 700,000 people of which about 121,000 had diabetes and all of them were hospitalized with a heart attack in a ten-year period between Jan 2003 to Jun 2013.  

Study findings: According to the study findings recently published in the Journal of Epidemiology and Community Health, those with diabetes (high sugar levels) were 56 percent more likely to die if they had a heart attack (caused by fully blocked coronary artery). Diabetics who had a heart attack due to partially blocked coronary artery, the chances of death in those patients were 39 percent, the study found.

"These results provide robust evidence that diabetes is a significant long-term population burden among patients who have had a heart attack," said lead researcher Dr. Chris Gale, a consultant cardiologist and associate professor at the University of Leeds, UK.

Though most patients survive a heart attack the long term effects of diabetes in heart attack survivors needs greater focus says Dr. Gale.

Why is heart disease so common in Diabetics?

Though it is known that diabetics who suffer a heart attack are less likely to survive, the researchers are trying to establish if this observation was due to having diabetes or if it is due to other conditions normally seen in diabetic patients. Not just blood glucose levels but other mechanisms also play a role in leading to cardiovascular disease in people with diabetes.  The blood vessels in patients with diabetes become more susceptible to other risk factors such as high cholesterol, high BP, smoking etc. More than 90% of patients with diabetes have one or more of these additional risk factors.

The weak blood vessels in diabetes patients could be due to the long-term effects uncontrolled blood glucose levels on the tissues. Overweight, sedentary lifestyle and poor blood glucose control contribute to higher change of high blood pressure and irregular blood lipids (i.e., high cholesterol, high triglycerides and a low level of HDL cholesterol).

The findings stress the importance of developing improved ways of preventing heart disease in people with diabetes and also improve survival after a heart attack.
