Cardiomegaly is a medical term that means an enlarged heart. This condition is not a disease itself, but rather a sign of another underlying health issue. It can occur as a result of various factors, including high blood pressure, heart valve disease, or heart muscle disease (cardiomyopathy).
When the heart is enlarged, it may struggle to pump blood effectively, which can lead to various complications, such as heart failure. Symptoms can vary; some people may experience none at all, while others may suffer from shortness of breath, fatigue, or palpitations.
Diagnosis usually involves imaging tests such as an echocardiogram or chest X-ray, which help doctors see the size of the heart and assess its function. Treatment focuses on addressing the underlying cause of the enlargement, which may include lifestyle changes, medications, or in some cases, surgery.
