People who undergo cardiovascular procedures such as coronary artery bypass surgery or even angioplasty are at a higher risk of suffering a heart attack or stroke. But one study found that other surgeries may raise the odds as well.

A research team from New York University School of Medicine looked at the risk of heart attack and stroke in procedures performed for other reasons.

The researchers analyzed data from more than 10 million hospitalizations between 2004 and 2013, looking for heart attacks, strokes, and death after surgeries that weren’t heart-related. They saw these complications in about 3 percent of cases.

The rates were highest for vascular, thoracic, and transplant surgeries (7.7 percent, 6.5 percent and 6.3 percent, respectively). Obstetric and gynecologic surgeries had the lowest risk, the authors reported in JAMA Cardiology.

Patients who had one of these complications were generally older, male, and more likely to have risk factors such as obesity, tobacco use, alcohol abuse, hypertension, diabetes, and kidney disease.

The researchers estimate that about 150,000 heart attacks and strokes occur each year in the U.S. following noncardiac surgeries.

This study indicates that doctors need to watch cardiac markers after those procedures.
