Dr. John Gierula is an NIHR Post-Doctoral Research Fellow and Lecturer at the School of Medicine, University of Leeds, within the Faculty of Medicine and Health. His dual role combines clinical cardiac physiology expertise with academic research, focusing on optimizing pacemaker therapy for heart failure patients through innovative device programming and cardiac function assessment.
His educational trajectory includes a BSc(Hons) in Clinical Cardiac Physiology (2001), PGDip in Healthcare Research, and PhD (2017) from the University of Leeds. His doctoral work established foundational protocols for pacemaker optimization in heart failure management.
Research interests center on personalized pacemaker programming to enhance cardiac contractility and exercise capacity in heart failure patients. Key innovations include algorithms reducing unnecessary right ventricular pacing and methods for individualizing heart rate rise settings based on non-invasive contractility measurements. His work bridges clinical electrophysiology, cardiac imaging, and exercise physiology to address pacemaker-related heart failure progression.
Analysis of his recent 15 publications reveals dominant themes: heart failure with preserved ejection fraction (HFpEF) biomarker discovery (e.g., cardiac contractility index), socioeconomic determinants of heart failure outcomes, and critical evaluation of emerging pacing technologies like multi-point CRT and conduction system pacing. His work increasingly integrates comorbidity trajectories and diabetic cardiometabolic pathways with device therapy.
Scientific recognition includes:
- 2019 National Healthcare Science Award for Excellence in Research and Innovation
As an educator, he serves as Module Lead for Biological Basis of Healthcare 1 and 2 and supervises postgraduate researchers including Nurul Abdul Samad. Major funding sources include his NIHR Post-Doctoral Fellowship (examining long-term effects of personalized pacemaker programming) and a Medtronic External Research Program investigating multi-point pacing effects on cardiac contractility.
He actively contributes to the Leeds Institute of Cardiovascular and Metabolic Medicine and Multidisciplinary Cardiovascular Research Centre, collaborating on cardiac electrophysiology studies and heart failure pathway optimization initiatives.
