Update from the Division of Cardiovascular Medicine

The following is a guest post from Barry London, MD, PhD, Director of the Division of Cardiovascular Medicine. It is part of an ongoing 2019 series of division updates.

The Division of Cardiovascular Medicine continues to excel and promote great research, education, and clinical service.

Clinical Updates

Our clinical service in the Heart & Vascular Center continues to grow, with increasing volumes in outpatient clinics at University of Iowa Hospitals & Clinics, Iowa River Landing (IRL), and in outreach locations, in procedures and imaging. General Cardiology visits were up 11% from FY18 to FY19, with help from our 48-hour new patient appointment campaign that kicked off in the Fall of 2018. Electrophysiology (EP) and Interventional procedure growth continues, with EP procedures showing a 12% growth from FY18 to FY19. Echo Imaging also realized an 8% growth from FY18 to FY19, and currently through FY20, shows an 18% overall increase from the same period last year.

Denice Hodgson-Zingman, MD, has accepted the position of Director of the Electrophysiology Section, effective July 1, 2019. She continues to show great skill and dedication in her clinical, educational, and research roles and shows great promise as Section Head.

Paulino Alvarez, MD, accepted the position of Interim Director of the Cardiomyopathy Section, effective July 1, 2019. He has played a central role in all aspects of the heart failure, transplantation, and advanced mechanical circulatory support programs.

Mahi Ashwath, MD, and Isabella Grumbach, MD, PhD, have started a new cardio-oncology program, to treat cardiac complications of patients that result from the growing array of cancer therapies. The program continues to show growth.

Our Hypertrophic Cardiomyopathy Center in the Cardiovascular Genetics Program was recognized as a Center of Excellence by the Hypertrophic Cardiomyopathy Association (HCMA) in 2019. This is a great achievement and congratulations are owed to Ferhaan Ahmad, MD, PhD, who directs the program.

Educational Updates and Achievements

After ten years as Director of the Cardiovascular Medicine Fellowship Program, Paul Lindower, MD, stepped down as Director. Dr. Lindower was a great advocate for fellows and is an incredible teacher and leader. He will still be involved in the program as we transition the directorship to Ferhaan Ahmad, MD, PhD.

François Abboud, MD, and Kaikobad Irani, PhD, were among the Internal Medicine faculty members that were honored at UI Carver College of Medicine Wall of Scholarship in March 2019. The Wall of Scholarship was established to highlight biomedical research by acknowledging a distinct group of current UI Carver College of Medicine faculty members whose published research articles have made a significant impact on a particular field of science or medicine.

Mahi Ashwath, MD, was elected President of the Iowa Chapter of the American College of Cardiology (ACC). Her term will begin in 2020. In addition, she won the Lewis E. January teaching award, as voted on by the Fellows of the Division of Cardiovascular Medicine. The award is voted annually and honors excellence in clinical teaching.

Donald Brown, MD, won the Laureate Award in October 2018 from the Iowa Chapter of the American College of Physicians. Since 1987, the Laureate Awards have been given annually by the Iowa Chapter of the American College of Physicians as a mark of honor and recognition for achievement of excellence in internal medicine in the State of Iowa.

Colleen Campbell, PhD, MS, CGC received the Strategic Leader Award from the National Society of Genetic Counselors. The award is presented annually to one individual who has done an outstanding job of promoting the genetic counseling profession as a recognized and integral part of health care delivery, through such avenues as education, research, and public policy. In addition, she was instrumental in getting genetic counselor licensure approved by the state.

Mark Chapleau, PhD, received the 2019 Iowa Physiological Society Lifetime Achievement Award in recognition of a career devoted to science and to the professional society. He has gained national and international recognition for his work on the neural control of hypertension, the highest risk factor in cardiovascular disease.
