Dr. Michael Ghalchi, MD, FACC
Cardiologist near Union Square
He built three organizations to prevent heart attacks and strokes. He still sees you himself.
For 20 years, Dr. Michael Ghalchi has worked on one problem: heart care that is slow, scattered and stops at the door. His answers became three organizations, trusted by thousands of New Yorkers since 2010. And every MCVA visit is with him.
- He founded MCVA (2010). Same-day appointments available, testing in his own office, and every study read by him and explained to you by him.
- He founded Apollo 360 Health. A health-technology platform that keeps your care going between visits, for patients who enroll.
- He founded Apollo House. A physician-supervised center where exercise physiologists and a dietitian help you turn your plan into a healthier life.
And he still trains cardiology fellows and residents at NYU, works on new ways to prevent strokes, and is an NYPD Honorary Police Surgeon.
“I became a cardiologist to stop heart attacks and strokes before they happen. Everything I've built is for that.”

His work
A cardiologist, a teacher and a builder.
Dr. Ghalchi founded Manhattan Cardiovascular Associates in 2010 and is its medical director. Every visit at MCVA is with him. The tests his patients may need are done quickly in his own office, sometimes the same day, and he reads every study himself and goes over the results and images with each patient.
He teaches as well as practices. He is a Clinical Assistant Professor at NYU and a Clinical Instructor at NYU Grossman School of Medicine. He trains NYU residents and cardiology fellows, and is on the faculty at NYU, Mount Sinai and Lenox Hill.
In research, he is developing a data-driven algorithm to prevent strokes in at-risk patients and ultrasound methods to measure cardiovascular risk.
He founded Apollo 360 Health, which keeps care going between visits for patients who enroll, and Apollo House, a physician-supervised health and longevity center. He is Medical Advisor to Dr. B, a telehealth platform, and is a former medical advisor to health-technology startups.
As an NYPD Honorary Police Surgeon, he consults on the cardiovascular health of New York City police officers, officials and their families.
