Known for their compassion and thoroughness, our cardiologists are consistently rated among the top in patient satisfaction.
What is a Non-Interventional Cardiologist?
Not all heart concerns require procedures. While interventional cardiologists perform minimally invasive treatments like stents or valve replacements, non-interventional cardiologists specialize in the prevention, diagnosis, and medical management of heart disease.
Your doctor may refer you to a cardiologist if you experience symptoms such as chest pain, palpitations, shortness of breath, dizziness, or irregular heartbeats. You may also be referred if you have risk factors such as high blood pressure, high cholesterol, diabetes, or a family history of cardiovascular disease.
At CLS Health, our cardiology team provides comprehensive care through diagnostic testing, medication management, and lifestyle guidance—helping patients protect their heart health and reduce the need for procedures whenever possible.
We welcome both self-referrals and referrals from primary care physicians and other specialists.

FAQs
A non-interventional cardiologist specializes in diagnosing, treating, and managing heart conditions using medications, lifestyle changes, and non-invasive tests. They do not perform surgeries or procedures like stents, but focus on prevention and long-term heart health.
You should see a cardiologist if you have chest pain, shortness of breath, palpitations, high blood pressure, or risk factors like diabetes, high cholesterol, or a family history of heart disease.
They use non-invasive tests such as EKGs, echocardiograms, stress tests, Holter monitoring, and CT scans to evaluate your heart’s health and detect problems early.
A non-interventional cardiologist focuses on diagnosis, prevention, and medical management, while an interventional cardiologist performs procedures such as angioplasty or placing stents to open blocked arteries.
CLS Health accepts Medicare, Medicaid, and most major health insurance plans. Schedule an appointment with our experienced cardiologists to receive comprehensive heart care covered by your insurance.
