100% devoted to being one of America’s best hospitals for coronary interventions
When you’re 100 percent devoted to excellence, being the best hospital in Suffolk County for heart care isn’t enough. Instead, we set our sights on becoming one of the best in the nation—and we achieved that goal.

Who we are

From prevention and diagnosis, to minimally invasive treatments, to the most complex heart procedures— we’re advancing medicine and changing lives for the better. We have made significant investments, so that our experienced team can diagnose and treat patients in modern facilities and state-of-the-art cardiac catheterization and electrophysiology labs.  And after a procedure, our patients benefit from a brand-new cardiac recovery area for enhanced comfort and privacy.

Our hard work and achievements have been recognized with awards from the local to the national level.

  • Local: Southside is the first hospital on Long Island to be recognized for achievement in heart attack care by the American Heart Association with the Mission: Lifeline Gold Award. (By partnering with local emergency medical services and using technology that allows us to plan for the patient’s arrival, we’ve been able to offer some of the fastest emergency interventional cardiac care in the nation.)
  • State: The New York State Department of Health has recognized us as among the best in New York for coronary interventions, a procedure that clears blocked arteries in the heart.
  • National: We’ve ranked among the top 10 percent of hospitals in the country for coronary interventions in 2018™ according to Healthgrades, a leading online information resource for physicians and hospitals.

Because of our dedication to setting a new standard of care, more patients choose Southside for complex heart care than any other hospital on the east end—and that’s something we can truly be proud of.

Our comprehensive cardiac rehabilitation program includes monitored cardiac rehabilitation for people who are recovering from heart surgery, cardiac stenting, heart attack and even heart transplant.

Our cardiac care has been recognized by various organizations including Healthgrades, the New York State Department of Health and the Society of Thoracic Surgeons. And that exceptional care doesn't end when you leave the hospital.
