Cardiology is the medical specialty focused on diagnosing, treating, and preventing diseases of the heart and blood vessels. Cardiologists manage conditions like heart disease, heart failure, arrhythmias, and hypertension. Main Branches of Cardiology: Clinical Cardiology: Uses non-invasive tests (ECG, echo, stress tests) to diagnose and treat heart conditions. Interventional Cardiology: Performs procedures like angioplasty and stenting to treat blocked arteries. Electrophysiology: Manages irregular heartbeats using techniques like ablation. Heart Failure & Transplant Cardiology: Treats advanced heart failure and evaluates transplant needs. Preventive Cardiology: Focuses on heart disease prevention through lifestyle changes and risk factor control. Cardiologists collaborate with surgeons, radiologists, and primary doctors to provide holistic heart care. Early detection and prevention are key to maintaining heart health.
