December 15, 2011

While many people believe this, there has been little actual evidence.

Canadian researchers reviewed the records of 500 patients with heart problems over two winter seasons.

Of those patients , 7 percent started experiencing heart symptoms while shoveling snow.

Researchers also identified three main factors that put people at risk: Being male, having a family history of premature coronary artery disease and smoking.

The study was published in the journal Clinical Research in Cardiology.
