The field of cardiology features several subspecialties:

Non-invasive cardiologists are concerned only with diagnosing ailments.   They do not conduct surgery or provide other treatment. 

Interventional cardiologists perform invasive tests and procedures to diagnose and treat cardiac disease. 

Cardiovascular surgeons operate on the heart, veins and arteries.  Invasive non-interventional cardiologists perform cardiac catheterisations by placing a tube through a blood vessel to obtain a picture of the diseased portion of the heart. If a pacemaker is required, they would implant it. 

Heart surgery includes coronary bypass surgery (where a graft is made from a section of a vein or artery removed elsewhere in the body and used to carry blood around portions of narrowed vessels). Coronary bypass surgery is the most common procedure of this type. Other surgical procedures such as angioplasty and endarterectomy (surgically removing fatty deposits from closed or inflamed blood vessels), are often performed by cardiologists. In extreme cases, hearts may be transplanted from a suitable donor.

Other subspecialties included echocardiography, electrophysiology and nuclear cardiology.

In general, their tasks are to meet with patients to learn about their medical histories and symptoms, conduct diagnostic tests to determine the cause and nature of the disease, examine and interpret the test results and explain them to the patients.

Education as an important part of the job - cardiologists explain the tests and procedures to their patients. They then discuss possible treatment methods with the patients, prescribe medication, conduct non-invasive procedures or perform surgery.

They need to coordinate medical staff for tests and procedure, recommend postoperative care, and educate the patients about how to lead healthier lives, for example, by following special diets and doing regular exercise. 

Patient records must be kept, and education continued by attending conferences and reading medical publications.  These doctors work with a wide range of patients, from children to seniors.

Among thetypes of medical equipment cardiologists use to make their diagnoses are x-rays, electrocardiograms, magnetic resonance imaging (MRI), and ultrasound imaging.  They also conduct angiography, arteriography and stress tests, and draw and examine samples of the patients' blood.

Cardiologists may prescribe medication and recommend special diets and exercise to a patient. They also perform corrective surgery where necessary. Cardiologists sometimes work in conjunction with anaesthetists.
