Unexplained fatigue during routine activities like climbing stairs or carrying groceries might be more than just a sign of stress or aging, cardiologists caution. If this tiredness persists or worsens, it could indicate a heart-related issue. Specifically, a heart valve disorder might be to blame. The heart’s four valves ensure blood flows properly, but if a valve becomes narrow, stiff, or leaky, it forces the heart to exert extra effort, reducing oxygen supply to muscles and organs and thus causing fatigue.
Conditions such as aortic stenosis and mitral regurgitation exemplify valve-related problems where blood flow is restricted or leaks backward, impairing heart function. Unlike typical fatigue from lack of sleep or stress, which usually improves with rest, fatigue due to heart valve issues often persists even after physical exertion and can gradually disrupt daily activities. It is crucial to recognize accompanying symptoms, including shortness of breath during minimal exertion, chest discomfort, dizziness, irregular heartbeat, and swelling in extremities or the abdomen.
Often, heart valve issues go unnoticed initially because the heart compensates by working harder, with symptoms becoming apparent only during exertion. This can lead people to mistakenly attribute symptoms to aging or poor fitness. Those particularly at risk include older adults and individuals with high blood pressure, diabetes, previous heart infections, or a history of rheumatic fever. However, younger individuals may also face these issues due to congenital defects or infections.
Routine health check-ups are emphasized by doctors for early detection, as heart valve problems can sometimes be identified through a heart murmur heard during a medical examination. Follow-up tests may include echocardiograms, ECGs, stress tests, or CT scans if necessary. The treatment approach varies according to the severity of the condition: while mild cases might only need monitoring and lifestyle adjustments, more severe cases could require valve repair or replacement, including the option of minimally invasive procedures.
