What does a cardiologist do?

A cardiologist is a medical doctor who specializes in diagnosing, treating, and preventing diseases and conditions related to the heart and blood vessels. They perform tests such as echocardiograms, stress tests, and electrocardiograms to assess heart health. Cardiologists manage conditions like heart attacks, arrhythmias, heart failure, and hypertension, and often work with patients to reduce risk factors for heart disease. They may also coordinate care with other specialists for comprehensive treatment.
