The Northern New England Cardiovascular Disease Study Group (NNECDSG), is a regional voluntary consortium founded in 1987 to provide information about the management of cardiovascular disease in Maine, New Hampshire and Vermont. The group adopted the following mission statement:

The Northern New England Cardiovascular Disease Study Group exists to develop and exchange information concerning the treatment of cardiovascular disease. It is a regional, voluntary, multi-disciplinary group of clinicians, hospital administrators, and health care research personnel who seek to improve continuously the quality, safety, effectiveness, and cost of medical interventions in cardiovascular disease.

The NNECDSG maintains registries for all patients receiving coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), heart valve replacement surgery, transcatheter aortic valve replacement (TAVR) and other sturctural heart procedures. During the last thirty years, data on >190,000 procedures were collected and analyzed. The group meets twice a year to review data reports and to plan studies. They have published over 120 peer-reviewed articles.

An executive committee composed of a cardiologist, a surgeon, and an administrator from each institution and the data center director constitutes the administrative structure for the group.

Who We Are
Members include cardiothoracic surgeons, interventional cardiologists, operating room and cardiac ICU nurses, anesthesiologists, perfusionists, administrators, and scientists associated with six institutions in northern New England. The sites are: Catholic Medical Center, Manchester, NH (one affiliate Parkland Medical Center, Derry, NH); Concord Hospital, Concord, NH; Dartmouth-Hitchcock Medical Center, Lebanon, NH; Univeristy of Vermont Medical Center (formally Fletcher Allen Health Care), Burlington, VT; Maine Medical Center, Portland, ME.

The NNECDSG Database
The database tracks the clinical outcomes of all revascularization and structural heart procedures performed by the participating institutions. From these databases regional outcomes have been tracked and risk-adjusted models have been developed. Our prediction models are used to develop decision making tools for clinicians and their patients/families. These are available for your use (decision making tools). Our region and center specific report for isolated CABG surgery is available on our website.
