Research Post : Researchers get cardiac muscle cells to grow, repair heart attack damage

Heart attacks cause both long- and short-term problems. 

In the short-term, the death of cardiac muscle cells can cause a critical drop in the heart's ability to function. 

Over the long haul, problems arise because the damage is largely repaired by scar tissue, rather than functional muscle. 

For the most part, once cardiac muscle cells stop dividing (in most species, this occurs shortly after birth), they don't ever start again. 

That means that once they're lost in a heart attack the damage is essentially permanent.

And their hearts are ageing faster than their real age. Here are the common perceptions that the study blows apart: Your biological  age is the same as your heart age REALITY  "Calendar age has little to do with organ function.  People remain much younger than their birth age if they look after themselves," says Dr Prashant Joshi of Government Medical College, Nagpur, who led the Indian chapter of the interheart study. "The risk factors affect blood vessels, which in turn affect the heart. The 17th century physician Thomas Sydenham had once famously said, you are as old as your arteries," he adds. "Changing one's lifestyle is very difficult. Knowing the heart age can motivate people to adopt a healthy lifestyle." Indians are genetically vulnerable to heart dis...

Dated : 11-JUL-2013 Source : www.saffolalife.com What is Heart's Age? Did you know that your heart can actually have an age, which can be different from your actual age. The Science behind the Heart's Age. The Framingham Heart Study provides a quantification of the risk of cardio vascular disease in the form of the Heart's age. The objective is to guide people in preventive heart care*. What are its implications? Knowing your Heart's age can help you take the right action to keep your heart young. Many factors affecting your Heart's age are within your control. Your choice of a heart-healthy lifestyle can go a long way in making sure your heart stays young. Disclaimer: This calculator is only meant for people who do not suffer from cardiovascular diseases at the present such as heart attack, stroke, angina, heart surgery. The calculator is not applicable for pregnant and lactating women. The calculator might underestimate the heart disease risk for women....
