Cardiologists study and treat disorders related to the heart and blood vessels, otherwise known as the cardiovascular system. They will carry out tests and procedures, such as heart catheterizations, angioplasty and inserting a pacemaker.
What does a Cardiologist Treat?
People are referred to a cardiologist when they experience symptoms of a heart condition, such as shortness of breath, dizziness, chest pains, changes in heart rate or rhythm and high blood pressure. They often treat patients who have had a heart attack, heart failure, or other heart conditions and diseases. They help make decisions on treatment plans, such as surgery, heart catheterizations, angioplasty or stenting.
People may be referred to a cardiologist even if they have not shown symptoms. If they have a family history of heart disease or high cholesterol, if they are smoker or have diabetes, they may be a good candidate to see a cardiologist.
