A spice commonly found in curry dishes could help patients in Europe to prevent coronary failure and repair damaged hearts.
Studies carried out in mice showed that a compound called curcumin found in turmeric helped enlarged hearts by increasing blood flow and mending scarred tissues.
Now Canadian scientists hope that the discovery, published in the Journal of Clinical Investigation, could also apply to humans.
Researchers admit that they are still uncertain why the ingredient produced such benefits, but claim that turmeric may switch off the genes which cause the heart to become enlarged and damaged.
"Curcumin's ability to shut off one of the major switches right at the chromosome source where the enlargement and scarring genes are being turned on is impressive," the study's author Dr Peter Liu said.
Heart failure, commonly caused after a heart attack or high blood pressure, leads the heart to gradually lose the ability to pump blood efficiently around the body.
Despite drugs to control the condition, it also results in scarring and damage to the heart that is very difficult to heal.
Tending to affect people aged 65 and over, the condition is more prevalent in men than women.
