Experiencing fatigue from activities like climbing stairs, short walks, or carrying groceries is often attributed to factors such as stress, aging, lack of sleep, or poor physical fitness. However, cardiologists caution that persistent tiredness during everyday tasks might indicate a deeper heart issue. They emphasize that ongoing or worsening fatigue could be a sign of a heart valve disorder, where the heart’s valves are not functioning properly, causing the heart to exert more effort to circulate blood.
The heart is equipped with four valves that ensure blood flows in the right direction. When these valves become narrow, stiff, or leaky, the heart must work harder, which can limit the oxygen supply to muscles and organs, resulting in constant fatigue even with minimal exertion. Common valve-related issues include aortic stenosis and mitral regurgitation, where blood flow is either restricted or leaks backward, impairing the heart’s efficiency.
Health professionals explain that fatigue from heart valve problems differs from ordinary tiredness due to stress or lack of sleep. Unlike typical fatigue that improves with rest, heart-related tiredness may persist after exertion and gradually disrupt daily activities. Alongside fatigue, other warning signs may include shortness of breath during light activity or when reclining, chest discomfort, dizziness, irregular heartbeat, and swelling in the feet, ankles, or abdomen. Episodes of fainting or near-fainting may also occur.
Specialists note that heart valve issues can remain unnoticed in the early stages because the heart compensates by working harder, making symptoms more apparent during physical exertion. This often leads individuals to dismiss them as signs of aging or poor stamina. Older adults, particularly those with conditions like high blood pressure, diabetes, prior heart infections, or a history of rheumatic fever, are at increased risk. Nonetheless, younger individuals may also develop valve issues due to congenital defects or infections.
Regular health check-ups are crucial for early detection, according to doctors. Heart valve problems might be initially detected through a heart murmur during a physical exam, with further confirmation via tests like echocardiograms, ECGs, stress tests, or CT scans. Treatment varies based on the condition’s severity; mild cases may only require monitoring and lifestyle adjustments, whereas more severe cases could necessitate valve repair or replacement, including advanced minimally invasive procedures.
