What Conditions Do Cardiologists Treat?

Coronary Artery Disease: Coronary artery disease occurs when plaque builds up in the arteries that supply blood to the heart, restricting blood flow and potentially leading to a heart attack. Houston Methodist cardiologists work with patients to diagnose coronary artery disease and develop treatment plans that may include lifestyle changes, medications, procedures or surgery when needed.

Heart Failure: Heart failure occurs when the heart cannot pump enough blood to meet the body's needs. Cardiologists can help diagnose the type and severity of heart failure and develop a treatment plan that may include medications, lifestyle changes, medical devices or advanced therapies for more complex cases. Learn more about heart failure → 

Atrial Fibrillation (AFib): Atrial fibrillation, or AFib, is an irregular and often rapid heart rhythm that can affect blood flow and increase the risk of complications such as stroke. Cardiologists and electrophysiologists can evaluate AFib and recommend treatments such as medication, catheter ablation or other procedures based on your condition.  Learn more about atrial fibrillation → 

Heart Valve Disease: Heart valve disease occurs when one or more of the heart's valves do not open or close properly, affecting blood flow through the heart. Cardiologists and other heart specialists can evaluate valve disease and determine whether monitoring, medication, catheter-based treatment or surgery may be appropriate.

High Blood Pressure (Hypertension): High blood pressure occurs when blood pressure remains elevated over time and can increase the risk of heart attack, stroke, heart failure and other complications. Cardiologists can help evaluate cardiovascular risk and develop a plan to manage blood pressure through lifestyle changes, medication and ongoing monitoring. Learn more about high blood pressure →

Your primary care physician may refer you to a cardiologist when you have symptoms, risk factors or test results that suggest a heart or vascular condition. In general, it may be time to see a cardiologist when: 

• You have chest pain, pressure or discomfort that needs evaluation. 
• You experience shortness of breath, dizziness, fainting or unexplained fatigue. 
• You notice heart palpitations, an irregular heartbeat or a persistently rapid heart rate. 
• You have high blood pressure, high cholesterol, diabetes or other cardiovascular risk factors that require specialized management.
• You have been diagnosed with a heart condition or need a second opinion about a cardiovascular diagnosis or treatment plan. 

 
Chest pain, severe shortness of breath, fainting or other symptoms of a possible heart attack or other medical emergency require immediate emergency care. Do not wait for a cardiology appointment.  

How to Choose a Cardiologist 

Choosing a cardiologist is an important decision. A few things worth considering: 

Experience with your condition. Look for a cardiologist who regularly diagnoses and treats your specific heart condition or symptoms. 

Subspecialty expertise. Cardiology includes areas such as interventional cardiology, electrophysiology, heart failure, preventive cardiology and cardiovascular imaging. Your condition may determine which type of specialist is most appropriate. 

Treatment options. Ask about the range of treatment options available, including medications, lifestyle changes, catheter-based procedures and surgery when appropriate. 

Coordinated care. Complex heart conditions may require multiple specialists. A coordinated cardiovascular team can help bring together the expertise needed for your care. 

Communication and shared decision-making. Your cardiologist should explain your diagnosis and treatment options clearly and give you an opportunity to ask questions and participate in decisions about your care.
