Cardiologist
Diagnose, treat, and prevent diseases of the heart and blood vessels.
What is a Cardiologist?
Cardiologists specialize in the diagnosis and treatment of heart and vascular diseases. They perform diagnostic tests like EKGs and echocardiograms, prescribe medications, and perform procedures such as angioplasty and stent placement. Cardiologists also counsel patients on lifestyle changes to prevent heart disease.
A cardiologist's day centers on assessing patients: reviewing symptoms, ECGs, labs, and echocardiograms to stratify risk and decide interventions. Clinic visits, medication titration, and scheduling targeted imaging alternate with consultations for acute chest pain or heart failure. Attention to detail and cautious medication changes fill routine practice, and coordination with other teams informs procedures or surgical planning.
