According to a new study, almost 2 million persons worldwide undergo cardiac surgery each year. Measuring blood levels of a specific protein could help determine their mortality risk within 30 days.

As per US News, blood tests to examine troponin (a protein present in the heart muscle) levels have long been used to assess the risk of death and significant sequelae following a heart attack, but they are not routinely performed following heart surgery.

According to a new study, increased troponin levels were linked to an increased risk of death after cardiac bypass or open-heart surgery.

“This study is a watershed moment for health care teams caring for patients following heart surgery,” study co-author André Lamy, a professor of surgery at McMaster University in Canada, stated.

In a university news release, Lamy added, “For the first time, we have a marker that is rapid and reliable for the surveillance of these patients after heart surgery.”

This study comprised over 16,000 adult cardiac surgery patients from 12 countries, with an average age of 63. More than 2% of patients died within 30 days of surgery, and about 3% suffered a severe vascular complication, such as a heart attack, stroke, or a life-threatening blood clot.

Troponin levels were tested before and after surgery daily during the first few days.

“We discovered that the troponin levels associated with an increased risk of death within 30 days were significantly higher — 200 to 500 times the normal value — than the troponin levels that surgical teams are currently told defines the risk of a patient having one of the most common complications after heart surgery — myocardial injury, a heart muscle injury associated with increased deaths,” said P.J. Devereaux, lead study author. He’s a cardiologist at Hamilton Health Sciences and a senior scientist at McMaster University.

The findings were published in the New England Journal of Medicine on March 2.
