Book a Cardiac Checkup Before Running a Marathon

Running a marathon makes the heart work very hard.

Most people who run marathons are healthy.

However, some people may have heart problems without knowing it.

These problems can be inherited or develop over time.

One inherited condition is hypertrophic cardiomyopathy, which makes the heart muscle unusually thick.

Another is coronary artery disease, caused by blockages in heart arteries.

Some conditions do not cause noticeable symptoms during normal activities.

Very intense exercise can sometimes reveal these hidden problems.

A cardiac checkup before a marathon may help identify potential risks.
