It is well-known that sugar consumption in diabetics is harmful. But very few know that controlling sugar intake can keep their heart healthy.

According to our expert Dr Rajiv Kovil, leading diabetlogist,diabetes is a vascular disease that affects almost all organs and systems in your body. One of the most important thing diabetes tends to affect is your blood circulation, which increases the risk of heart disease. How, you ask? Well, Dr Tilak Suvarna, Interventional Cardiologist and Head of Cardiology, Asian Heart Institute tells you all you need to know about the relation between heart disease and diabetes and how you can prevent its progression.

Keeping blood sugar levels under good control for many years can reduce the risk of suffering a heart attack, stroke, heart failure or amputation by about 17 percent among Type 2 diabetics, a key study has revealed. They may not have to keep their blood sugar levels super-low to reap most of the cardiovascular benefits.

A long-term average of about eight on the measurement called Hemoglobin A1c was enough to ensure most of the benefits, but this in many patients can be safely lowered to around seven. Hemoglobin A1c test is used as a standard tool to determine blood sugar control for patients with diabetes. It checks what percentage of your hemoglobin - a protein in red blood cells that carries oxygen - is coated with sugar (glycated). 'This finding reinforces the importance of combining good blood sugar control with control of other cardiovascular risk factors for a combined effect,' said lead study author Rodney Hayward of the VA Ann Arbor Healthcare System and University of Michigan Medical School.

For anyone with Type 2 diabetes, a growing body of research supports the idea of taking four medications to help their hearts: metformin to control blood sugar, a statin to control cholesterol and other blood lipids, a blood pressure medication and aspirin. This quartet of drugs, combined with proper diet and exercise, and quitting of smoking, could help millions of people stave off heart attacks, strokes, heart failure and amputations. They may also help prevent other medical issues that can arise from the effect of diabetes on small blood vessels, including blindness, nerve pain or numbness, and kidney failure. For the results, the researchers analysed 1,800 veterans with Type 2 diabetes, nearly 10 years after they signed up for a six-year blood sugar study.

The results were reported in the New England Journal of Medicine.
