"The American College of Cardiology (ACC), a 39,000-member nonprofit medical society, is dedicated to enhancing the lives of cardiovascular patients through continuous quality improvement, patient-centered care, payment innovation and professionalism. Comprised of physicians, nurses, nurse practitioners, physician assistants, pharmacists and practice managers, the College bestows credentials upon cardiovascular specialists who meet its stringent qualifications. Above all, the ACC’s commitment to its members and their patients has driven the College to be a leader in the formulation of health policy, standards and guidelines, and a steadfast supporter of cardiovascular research. The ACC provides professional education and operates national registries for the measurement and improvement of quality care."
I don't see the issue with an RN leading the group if it's a multidisciplinary group. Especially since in their mission statement it's clear that it's 1) multidisciplinary and 2) not a cardiologist advocacy group (as might be suggested if they were named the "American College of Cardiologists.")
In PM&R, one of our primary sub-specialty professional groups for spinal cord injury medicine (ASCIP) is the same--it's full of physicians, RNs, PTs, OTs, SLPs, MSWs, etc. It's president the next year is a PT.
I've found ASCIP's meetings actually far more fun, interesting, and informative than physician-only conferences I've been to...
