Even High Performing Athletes Can't Escape Cardiovascular Disease Risk

Middle-aged athletes, though maintain their fitness by exercising can't outrun cardiovascular disease risk, reports a new study. The findings of the study are published in the journal BMJ Open Sport and Exercise Medicine.

The study highlights how important it is for middle-aged athletes to have their doctor check their cardiovascular risk factors, especially if they have high blood pressure, high cholesterol or a family history of cardiovascular disease.

Cardiovascular disease refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain (angina) or stroke.

"We all know that exercise is good for us it can help prevent a range of health problems and diseases, from cancer to depression," said Barbara Morrison, the study's lead author and a Ph.D. student in experimental medicine at UBC. "However, even if you are active, our findings suggest that you still can't outrun your risk factors."

For the study, researchers followed 798 "masters athletes" adults aged 35 and older who engage in moderate to vigorous physical activity at least three days a week. The participants included a range of athletes, from runners to cyclists, triathletes, rowers and hockey players.

In coronary heart disease, blood is unable to flow through blocked arteries. The main symptom is chest pain or angina. Treatment is with medications or surgery.

Participants were asked a range of questions about their health, family history, and physical activity levels. They also had their blood pressure checked and waist circumference measured. Some participants also took part in an exercise stress test. Those with abnormal results underwent further testing, such as a CT coronary angiogram, to determine if they had cardiovascular disease.

Of the 798 athletes, 94 (11 percent) were found to have the significant cardiovascular disease. Ten participants were found to have severe coronary artery disease (a blockage in their artery of 70 percent or greater) despite not having any symptoms.

This study's findings build on previous research that found masters athletes have a higher incidence of cardiovascular disease than non-athletes of the same age with similar risk factors. However, previous research has also found that, compared to non-athletes, masters athletes typically have more calcified plaque, which is known to be more stable and less likely to cause a heart attack.

While the findings may seem alarming, Morrison emphasized that it doesn't mean masters athletes should stop exercising.

Rheumatic Heart Disease (RHD) - Causes, Risk factors, Symptoms, Diagnosis, Treatment
Rheumatic heart disease is a sequelae of rheumatic fever that affects heart valves. Rheumatic fever occurs after an episode of strep throat or sore throat due to group A beta hemolytic streptococci.

She recommends people see their doctor for regular check-ups, including blood pressure and cholesterol monitoring, especially if they have a family history of heart attack or stroke.

"The good news is that cardiovascular disease is treatable," she said. "Medication has been proven to reduce mortality risk, and even more so in people who are active."

Practicing moderation when it comes to exercise is also important, she added. "There is no evidence that pushing exercise to the limit will make you live longer or your heart stronger, but when taken to the extreme, it may have the potential to do harm," said Morrison. "You should never push yourself so hard that you can't exercise the next day."
