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.
Marathons place significant stress on the cardiovascular system.
Most athletes are healthy, but some may have undiagnosed heart conditions.
Inherited conditions can include hypertrophic cardiomyopathy, which thickens the heart muscle.
Acquired conditions can include coronary artery disease caused by blocked heart arteries.
Some heart conditions remain silent until intense physical activity triggers symptoms.
