Do You Need to See a Cardiologist?

Cardiologist consultations are typically recommended by a patient's primary care physician in response to either heightened risk factors for cardiovascular disease or symptoms that indicate it may already be present.

Because heart disease is America's number one killer—affecting over 30 million people—physicians are keenly aware of the stakes in detecting or diagnosing it.

Major risk factors for heart disease, such as one or more immediate family members being affected as well as high blood pressure or cholesterol readings, may prompt your primary physician to refer you to a cardiologist. This referral may result in either a one-time visit or ongoing care, depending on the results.

A strong family history of heart disease, for example, may be the catalyst for an evaluation or for low-level tests to check heart function. If results prove normal, you may continue to be monitored by your primary care physician. More ominous findings, however, may spur further testing that can result in long-term cardiology care. You can estimate your own risk for heart disease.

More commonly, certain symptoms cause patients to seek cardiology care that include:

• Chest pain or discomfort is known as angina, which often indicates narrowed arteries providing blood to the heart
• Rhythm disturbances called arrhythmias, which can include palpitations or missed heartbeats
• Shortness of breath, which can indicate congestive heart failure or valve problems
• A cardiac event, such as a heart attack, which requires ongoing cardiology monitoring after the emergency passes

The field of cardiology has several subspecialties in which the cardiologist concentrates on specific heart problems. A patient's particular heart problem dictates which type of cardiologist is needed.

Some of the subspecialties of cardiology include:

• Cardiovascular surgeons, who perform coronary bypass surgery or other surgical procedures
• Invasive cardiologists, who use tubes called catheters to perform angiograms, which can indicate narrowed arteries around the heart
• Echocardiographers, who use equipment to create images of the heart in motion by the use of sound waves. These images can show how well the heart is pumping and if the valves are working normally or not.

Preventive cardiology is also a subspecialty. Many hospitals across the United States devote outpatient centers seek to prevent cardiac events by helping patients with lifestyle issues, such as weight, exercise or smoking. A retrospective clinical study, published in the journal, Preventive Cardiology, demonstrated that patients who participated in such programs had reduced cardiac risks.
