Obese Heart Patients At Greater Risk

Obese Heart Patients At Greater Risk
Obese and morbidly obese coronary patients are more likely to suffer infections and complications following heart surgery, according to cardiothoracic surgeons in Victoria.

Dr Cheng-Hon Yap, a cardiothoracic surgery registrar from St Vincent's hospital in Melbourne, and colleagues, say patients having coronary artery bypass grafting or heart valve surgery are 1.4 times more likely to be obese compared to the general adult Australian population.

Their findings, published in the latest Medical Journal of Australia, showed obesity was linked to wound infection and renal failure following operation.

"Morbid obesity was associated with prolonged ventilation, readmission to the intensive care unit and prolonged length of stay," says Dr Yap. "We did not find an increased risk of early mortality in patients with obesity or morbid obesity."

Unlike current Australian population data that suggest obesity was most prevalent in the 55- 74 year age group, the researchers found obesity to be most prevalent in heart surgery patients aged 35-54 years.

"This may be because doctors might consider elderly patients who are obese to be poor candidates for surgery," says Dr Yap.

"Younger obese patients are in comparison more likely to be referred for surgery as they are seen as having lower surgical risks and may have more to gain from the survival advantages conferred by cardiac surgery."

Dr Yap says their findings are similar to data from Europe, the UK and the United States, indicating that this trend is evident in most of the developed nations.

The Medical Journal of Australia is a publication of the Australian Medical Association.
