Cardiologist
A cardiologist is a medical doctor who specializes in diagnosing, treating, and preventing heart and blood vessel conditions (cardiovascular diseases). They focus on conditions like heart disease, high blood pressure, arrhythmias (irregular heartbeats), heart attacks, and other related issues. Cardiologists use various diagnostic tests, such as ECGs, echocardiograms, and stress tests, to evaluate heart function and determine the best treatment plans, which can include lifestyle changes, medications, or procedures like stenting or bypass surgery.
