Feeling unusually tired after activities like climbing stairs or carrying groceries is often attributed to stress, ageing, or lack of sleep. Yet, cardiologists caution that persistent fatigue during normal tasks might indicate an underlying heart condition. Specifically, they point to the possibility of a heart valve disorder. The heart’s four valves play a critical role in directing blood flow, and if any of these valves become narrowed, stiff, or leak, the heart’s workload increases significantly. This added strain can result in decreased oxygen delivery to muscles and organs, causing fatigue even after minimal exertion.
Heart valve disorders such as aortic stenosis and mitral regurgitation are notable examples where the heart’s efficiency is compromised. These conditions can restrict blood flow or cause it to leak in the wrong direction, impairing the heart’s performance. Unlike fatigue from stress or sleep deprivation, which typically resolves with rest, fatigue linked to heart issues persists and can disrupt everyday activities. Doctors advise that additional symptoms accompanying fatigue should not be overlooked. These include breathlessness during mild activity or when lying down, chest discomfort, dizziness, irregular heartbeats, swelling in the extremities, and fainting spells.
Many individuals might dismiss these symptoms, attributing them to ageing or lack of fitness, especially since heart valve problems often go unnoticed in their early stages. The heart initially compensates by working harder, masking the symptoms until they become evident during physical exertion. Older adults, particularly those with conditions like high blood pressure, diabetes, or a history of rheumatic fever, are at an increased risk. Nonetheless, younger individuals are not immune, as congenital defects or infections can also lead to valve issues.
To catch these problems early, regular health check-ups are crucial. Sometimes, heart valve issues are detected through a heart murmur during a routine exam, prompting further tests such as echocardiograms, ECGs, stress tests, or CT scans for confirmation. The treatment plan varies depending on the disorder’s severity. While mild cases might only require lifestyle modifications and monitoring, more severe conditions could necessitate valve repair or replacement. Fortunately, advanced minimally invasive procedures are available for such interventions.
