Determining if you need heart surgery typically involves a comprehensive evaluation by a cardiac specialist. Common indicators include persistent chest pain, shortness of breath, irregular heartbeat, or symptoms that don't improve with medication. Your doctor will review your medical history, perform diagnostic tests such as echocardiograms or cardiac catheterization, and assess the severity of your condition. Surgery may be recommended if your heart condition is severe, progressive, or poses significant health risks that cannot be managed through non-surgical treatments.
