Cardiology is the branch of medicine that diagnoses, treats, and prevents heart and blood vessel disease. Cardiologists care for conditions such as coronary artery disease, heart failure, arrhythmias, valve problems, congenital defects, and high blood pressure.

They use tests like echocardiograms, electrocardiograms (ECGs), stress tests, and cardiac imaging to find issues early. Based on results, they create treatment plans that may include lifestyle changes, medicines, catheter-based procedures, or surgery with cardiac specialists.

The main goals of Cardiology are to improve circulation, strengthen heart function, and lower the risk of heart attacks or strokes. By combining preventive care with advanced therapies, cardiologists help patients live longer, healthier lives.
