Different Types of Cardiologists: Understanding the Specialists Who Care for Your Heart

When most people hear the word “cardiologist,” they think of a doctor who treats heart disease. While that’s true, cardiology is a broad field with several subspecialties, each focused on different aspects of cardiovascular health.

At Cardiovascular Associates of Mesa (CVAM), our physicians specialize in a variety of areas, ensuring patients receive the most appropriate care for their specific heart condition. Understanding the different types of cardiologists can help you know what to expect if you’re referred to a heart specialist.

General Cardiologist

A general cardiologist is often the first heart specialist a patient sees. They diagnose, treat, and help prevent a wide range of cardiovascular conditions while coordinating your overall heart care.

General cardiologists commonly evaluate and treat:

• High blood pressure (hypertension)
• High cholesterol
• Coronary artery disease
• Heart failure
• Heart valve disease
• Chest pain
• Shortness of breath
• Heart murmurs
• Heart palpitations

They also perform and interpret diagnostic tests such as electrocardiograms (EKGs), echocardiograms, stress tests, heart monitors, and cardiac imaging. Many patients continue seeing their general cardiologist long-term for routine cardiovascular care and disease prevention.

Interventional Cardiologist

Interventional cardiologists specialize in using minimally invasive catheter-based procedures to diagnose and treat blocked or narrowed arteries. Rather than performing open-heart surgery, they access the heart through blood vessels using specialized catheters.

Common procedures include:

• Coronary angiography (cardiac catheterization)
• Coronary angioplasty
• Coronary stent placement
• Peripheral vascular interventions
• Evaluation and treatment of blocked arteries

Interventional cardiologists often play a critical role in treating heart attacks and helping restore blood flow quickly, reducing damage to the heart muscle.

Structural Cardiologist

Structural cardiologists specialize in treating abnormalities of the heart’s valves, chambers, and other structural components using advanced minimally invasive techniques.

These specialists care for conditions such as:

• Aortic stenosis
• Mitral valve disease
• Tricuspid valve disease
• Patent foramen ovale (PFO)
• Atrial septal defect (ASD)
• Left atrial appendage management for select patients with atrial fibrillation

Many structural heart procedures can now be performed through small catheter-based approaches rather than traditional open-heart surgery. These innovative treatments may offer shorter recovery times while providing excellent outcomes for appropriately selected patients.

Cardiac Electrophysiologist (EP)

A cardiac electrophysiologist, often called an EP, is a cardiologist with advanced training in diagnosing and treating disorders of the heart’s electrical system. These specialists focus on abnormal heart rhythms, also known as arrhythmias.

An electrophysiologist may evaluate patients with:

• Atrial fibrillation (AFib)
• Atrial flutter
• Supraventricular tachycardia (SVT)
• Bradycardia (slow heart rate)
• Ventricular tachycardia
• Heart palpitations
• Fainting (syncope)

Electrophysiologists perform specialized procedures including:

• Ablation
• Pacemaker implantation
• Implantable cardioverter-defibrillator (ICD) placement
• Watchman implantation

These treatments help restore normal heart rhythm, improve symptoms, and reduce the risk of serious complications.

Which Type of Cardiologist Is Right for You?

Many patients begin their heart care with a general cardiologist, who can diagnose cardiovascular conditions and determine whether referral to a subspecialist is needed. Because these specialists work closely together, your care is coordinated to ensure you receive the most effective treatment for your condition.

At Cardiovascular Associates of Mesa, our team provides comprehensive cardiovascular care, from preventive heart health and routine evaluations to advanced interventional, structural heart, and electrophysiology procedures. No matter where you are in your heart health journey, our specialists are committed to delivering personalized, evidence-based care close to home.
