Diabetes can independently lead to heart failure
According to health experts in India, if poorly
controlled, diabetes leads to cardiomyopathy resulting in progressive
deterioration of pumping capacity of heart. “Diabetes is also a major risk factor for atherosclerosis and this
eventually leads to blockage of coronary arteries. This leads to heart attack
or myocardial infarction,” Satish Koul, HOD and Director Internal Medicine,
Narayana Superspeciality Hospital, Gurugram, told IANS.
“Due to
myocardial infarction, the heart muscle becomes weak and eventually heart fails
as a pump leading to congestive heart failure,” Koul added.
According to the current study, published in the
journal Mayo Clinic Proceedings, researchers evaluated the
long-term impact of diabetes on the development of heart failure, both with
preserved ejection fraction – a measurement of the percentage of blood leaving
the heart with each contraction – and reduced ejection fraction. They also
looked at mortality in a community population, controlling for hypertension,
coronary artery disease and diastolic function.
From an initial group of 2,042 residents of Olmsted
County in US, 116 study participants with diabetes were matched 1:2 for age,
hypertension, sex, coronary artery disease and diastolic dysfunction to 232
participants without diabetes.
Over the 10-year follow-up period, 21 percent of
participants with diabetes developed heart failure, independent of other
causes. In comparison, only 12 percent of patients without diabetes developed
heart failure. Cardiac death, heart attack and stroke were not statistically
different in the study between the two groups.
The study shows that diabetes is an independent risk
factor for the development of heart failure in the community dwelling
population.
