Heart cells are replenished throughout life: Swedish study

"Scientists have confirmed that heart cells are replenished throughout life, paving the way for better treatments to repair damage caused by cardiac arrest or illness, a Swedish study published Friday showed. Scientific research has shown that some of the body's cells are renewed each week while others are never replaced. A long debate has simmered over whether the heart's cells are replaced, with most cardiologists convinced until now that they are not. 'Researchers at Karolinska Institute have now shown that human heart cells undergo continual, slow replacement,' the Swedish institute said in a statement." - Khaleej Times
