Research and Scholarly Activity

A major contributor to the enhancement of a scholarly attitude is active participation in one or more research projects, ideally followed by presentation of the work at a national meeting and publication of a paper in a peer-reviewed journal.

At AHN, we’re committed to providing our cardiology fellows with rewarding research experiences. We encourage fellows to present at national meetings and submit manuscripts for publication in leading journals. In recent years, several fellows have published peer-reviewed journal articles and have presented numerous abstracts, posters, and oral presentations at local, regional, national and international meetings such as the American Heart Association (AHA) and the American College of Cardiology (ACC).

Program faculty members mentor fellows in a wide range of research interests. We support projects in quality improvement and patient safety. Fellows are allotted one month of research during the first and second years. We urge fellows to initiate projects during this time with completion occurring during the remainder of the training period. All fellows must present their research or quality improvement projects at the end of the year to all faculty.

A unique aspect of research at AHN is the collaborative opportunities available with research scientists at Carnegie Mellon University. Fellows may participate in ongoing projects or initiate new ones in cardiovascular disease.

The Division of Cardiology vigorously supports applications for American Heart Association (AHA) fellowship research grants, as well as funding from other local agencies. Opportunities in basic cardiovascular research are also available at the Cardiovascular Research Institute should any of the trainees be interested.
