Unusual fatigue during everyday activities like climbing stairs or carrying groceries might be more than just a result of stress, ageing, or poor fitness. Cardiologists caution that persistent tiredness in such scenarios can sometimes indicate a heart problem, particularly if it continues or worsens over time. A potential cause of this fatigue could be a heart valve disorder. The heart’s four valves ensure blood flows properly, and when these valves become narrow, stiff, or leaky, the heart must exert more effort to circulate blood, which can lead to reduced oxygen supply and resulting fatigue.
Common heart valve issues such as aortic stenosis and mitral regurgitation exemplify conditions where blood flow is either restricted or leaks backward, diminishing the heart’s efficiency. Experts highlight that heart-related fatigue is distinct from ordinary tiredness due to stress or lack of sleep. While normal fatigue typically improves with rest, fatigue linked to heart problems may persist even after mild physical activity and progressively interfere with daily life.
Accompanying symptoms might include shortness of breath during light activities or while lying down, chest discomfort, dizziness, irregular heartbeat, swelling in the extremities, or fainting episodes. Often, these symptoms go unnoticed initially because the heart compensates by working harder, and the signs become apparent mainly during physical exertion. This can lead individuals to mistakenly attribute them to ageing or poor stamina.
Heart valve issues can affect anyone, though older adults with high blood pressure, diabetes, past heart infections, or a history of rheumatic fever are more at risk. However, younger individuals may also face valve problems due to congenital defects or infections. Regular medical check-ups are crucial for early detection, as heart valve problems might be identified during an examination by detecting a heart murmur, followed by diagnostic tests like echocardiograms, ECGs, stress tests, or CT scans if necessary.
The treatment for heart valve disorders varies with severity. Mild cases might only need monitoring and lifestyle adjustments, while more severe conditions could require valve repair or replacement, including less invasive modern procedures. Early detection and proper management are key to addressing these potentially serious issues effectively.
