A cardiologist department is a medical department that specializes in the diagnosis, treatment and prevention of heart diseases. The doctor will perform all medical tests related to heart diseases and provide comprehensive treatment for the patient’s condition. Most cardiologist departments have an emergency room for patients who need immediate care.

The first step for many patients with chest pain is to see a primary care physician, such as an internist or family doctor. The primary care doctor can then refer them to a cardiologist if they feel it is necessary.

Cardiology is a medical subspecialty that focuses on the heart and blood vessels. Cardiologists perform diagnostic, interventional and therapeutic procedures to diagnose and treat disorders of the heart, blood vessels, lungs and kidneys.

Cardiology is a primary-care specialty that combines the skills of an internist or family doctor with those of an obstetrician or cardiologist. Cardiologists are often called upon to handle complex cases involving multiple organ systems.

Cardiologists are responsible for many types of cardiac problems such as heart attack, angina, arrhythmia, heart failure and abnormal heart rhythm. They also can help manage conditions related to high blood pressure and diabetes.

Most cardiologists work in private practice or hospital settings where they provide comprehensive care for their patients. They may be called upon to consult on medical emergencies related to the heart or other organs.
