Welcome to the Cardiac Fitness Center of St. Francis Hospital, The Heart Center - the only hospital-based program of its kind on Long Island.


The center is located on the park-like grounds of The DeMatteis Center for Cardiac Research and Education in Greenvale.


Located just off Northern Boulevard, its serene setting offers plenty of convenient and accessible parking.


Our popular fitness center enjoys more than 60,000 visits a year and recently celebrated its 30th anniversary.


Visitors are greeted by our friendly staff to make sure every exercise session feels like a welcome visit.


All of our cardiac fitness programs are medically supervised by a doctor, registered nurses and other healthcare professionals, who are always on site.


Our award-winning center is equipped with state-of-the-art exercise equipment.


The workout circuit includes bicycles, treadmills, weight lifting stations and an indoor walking track.


All patients are prescreened for an appropriate fitness plan to ensure all of their cardiac needs are met.


Everyone is continually monitored for their progress by our highly dedicated staff.


For more information on how you can step up to better health and how we can help, call (516) 629-2040.

The DeMatteis Center for Cardiac Research & Education

The DeMatteis Center for Cardiac Research & Education is located on Northern Blvd., in Greenvale, NY, approximately four miles east of the main campus of St. Francis Hospital. Click here for directions.

In addition to the Women’s Center, community health and other programs, the DeMatteis Center is the home to cutting edge technology for cardiac imaging. Under the leadership of Nathaniel Reichek, M.D., a world-renowned leader and pioneer in cardiac imaging, significant advancements in cardiac imaging have provided scientific knowledge that translates into improved care for patients with cardiac disease.

Cardiac MRI
Cardiac MRI
Novel imaging techniques have been developed in the last five years that have enabled cardiologists to better diagnose and treat cardiac disease.

An MRI of the heart, cardiovascular and vascular systems produces unique three-dimensional views via images produced by a large magnetic field. The measurements obtained during a procedure enable the physician to detect significant changes in a single patient or identify changes in a population during a research trial. The research physicians involved in MRI research at St. Francis Hospital are continually reviewing the images taken during the procedure and are working to establish and develop new imaging techniques.

An additional cardiac MRI was installed on the main campus of St. Francis Hospital in 2007 to enable physicians to obtain MRI images of the heart on the population of in-patients during their hospital stay.

Angiography and Calcium Score

64 Slice CT

Images are obtained via a 64-slice multi-detector CT scanner that allows physicians to analyze coronary artery lesions and blockages that were previously not visualized prior to the changes in the imaging technology.

CT Angiography is an application of CT that visualizes the coronary arteries non-invasively with unprecedented clarity and accuracy.

CT continuously gathers multiple images via thin x-ray scans or slices from multiple directions and is combined to form an image set.

Coronary calcium score is a screening test used to detect calcification in the coronary arteries and determine future risk of coronary artery disease before symptoms develop.

St. Francis Hospital is one of the only institutions with two designated 64-slice CT scanners. One is located on the main campus of St. Francis Hospital with an additional CT scanner located at the DeMatteis Center for Research and Education in Greenvale, NY.

Inpatients and outpatients that have a CT scan for clinical or research purposes will have the advantage of the most cutting edge technology available at both sites.

Echocardiography

By using three-dimensional echocardiography, images of the heart, obtained non-invasively with ultrasound, it is possible to evaluate the heart’s function more reliably than with a conventional ultrasound. It is especially useful in assessing patients with congestive heart failure. This technology creates a three-dimensional reconstruction of the heart, which provides detail on the extent of a patient’s heart disease and helps physicians recommend the most effective treatment option. St. Francis Hospital has active programs in the research and application of this technology.

Nuclear Imaging

Dr. Andrew Van Tosh, Director Nuclear Cardiology at St. Francis Hospital, is interested in research that includes the application of nuclear cardiologic techniques to the diagnosis and prognostic assessment of patients with coronary disease and other forms of cardiac illness. St. Francis Hospital has active programs in the research and application of this technology also.
