About me

Nicholas Andrew Paivanas, MD, is a board certified cardiologist. His interests include preventive cardiology, treatment resistant hypertension, lipid disorders, coronary artery disease, heart valve disorders, congestive heart failure, cardio-oncology, and cardiac imaging including echocardiography, transesophageal echocardiography, and nuclear cardiology.

His primary focus is educating patients in healthy lifestyle choices for reducing high cholesterol and controlling lipid abnormalities, to help prevent serious heart and vascular disease before it begins. Treating each case as unique, his emphasis is on preventive cardiology, simplifying hypertension therapy, valve disorders and lipid therapy. He strives to implement the best and most effective approach for each patient.

His approach with patients is to ensure that any intervention or medication fits with the lifestyle of each patient. This strategy provides the best specialized care and leads to greater success for patients.

    I love Dr. Paivanas so much that I recommended him to my husband. And now he is my husband's physician. My husband and I are always speaking highly of Dr. Paivanas. We've never had such an exceptional/phenomenal cardiologist as Dr. Paivanas.
