Want to calculate your risk of heart attack or stroke? This new online tool will help

Ottawa researchers say their new online calculator can give an idea of a person's chance of having a stroke or a heart attack within the next five years.

Their research,published Monday in the Canadian Medical Association Journal,says the calculatorlets people accurately predict their risk of both hospitalization or death due to cardiovascular disease.

If the calculator finds a person's risk to be, for example, five per cent, it means that five in 100 people with similar risk factors will experience a serious cardiovascular event in the next half decade.

Doctors don't necessarily ask about lifestyle factors that could put you at risk of a heart attack and stroke.- Dr. Doug Manuel,senior scientist at The Ottawa Hospital

"In cardiovascular disease, an ounce of prevention is worth a pound of cure,"said Dr. Doug Manuel, the paper's lead authorand a senior scientist at the Ottawa Hospital.

"We hope this tool can help people and their care team with better information about healthy living and options for reducing their risk of heart attack and stroke."

The calculator was based on data from Statistics Canada's health surveys andis available at an online health calculator website calledProject Big Life.

Risk number based on healthy living

While the risk forcardiovascular disease one of the leading causes of death in Canada is commonly assessed by measuring blood pressure and cholesterol levels,the new calculator bases its assessment on healthy living choices.

Using survey data from more than100,000 Canadians, the calculator analyzes factorsthat includealcohol consumption, diet, physical activity and whether the person is a smoker.

The calculator also takes into account a person's stress levels, theirsenseof belonging, their ethnicity, immigration status,socioeconomic status, education levels, and whether they already have diabetes or high blood pressure.

It then offers up a measurement of the person's"heart age."

"A lot of people are interested in healthy living, but often we don't have that discussion in the doctor's office," said Manuel, who is also a professor at the University of Ottawa.

"Doctors will check your blood pressure and cholesterol levels, but they don't necessarily ask about lifestyle factors that could put you at risk of a heart attack and stroke."
