Cardiology is the medical specialty focused on diagnosing, treating, and preventing diseases of the heart and blood vessels. Cardiologists manage conditions such as hypertension, coronary artery disease, heart failure, arrhythmias, and congenital heart disorders. They use diagnostic tools like ECGs, echocardiograms, stress tests, and cardiac imaging to assess heart function and detect abnormalities. Treatment may include medications, lifestyle modifications, minimally invasive procedures, or advanced interventions such as angioplasty and cardiac surgery in collaboration with other specialists. Cardiology plays a vital role in maintaining cardiovascular health, reducing the risk of heart attacks and strokes, and improving patients’ longevity and quality of life through early detection and comprehensive care.
