The hardest working muscle of our body, the heart beats 100000 times a day, 24x7 supplying essential nutrients and life-giving oxygen throughout the body. The heart pumps blood, which shuttles carbon dioxide to the lungs from where it is removed from the body. Hence, for life to sustain, the heart has to continue beating effectively, and it is for this very reason that the heart has to be taken care of.

More than 17.3 million deaths annually can be attributed to this disease, and by 2030, the number is expected to grow more than 23.6 million.

Some patients may not be suitable for heart transplant surgery, and certain conditions may increase the chances of complications. Conditions or ailments that suggest against the heart transplantation may be either absolute or relative.
