A/Prof Mahajan is a clinical academic appointed as Associate Professor in the Adelaide Medical School, The University of Adelaide and Clinical Lead for Cardiac Electrophysiology and Pacing at the Lyell McEwin Hospital, Northern Adelaide Local Health Network, South Australia.

A/Prof Mahajan graduated from the University of Delhi in December 1997. He undertook Physician training from the Delhi University and Cardiology training from the All India Institute of Medical Sciences, India. He worked in an academic position as Assistant Professor in Cardiology at the Post Graduate Institute of Medical Research and Education prior to undertaking Electrophysiology and Pacing Fellowship at the Royal Adelaide Hospital. During this time, he also completed his PhD at The University of Adelaide resulting in ground-breaking work that was instrumental in understanding the mechanistic link between obesity, epicardial fat and atrial fibrillation (AF). During the early career period, he was supported by fellowship co-funded by the NHMRC and NHF (2016-2020) and subsequently by The Hospital Research Foundation (2020-2022).

In 2017, A/Prof Mahajan was appointed to the position of a Clinical Academic in the Adelaide Medical School, The University of Adelaide and Lyell McEwin Hospital. During this time, A/Prof Mahajan has established a clinical electrophysiology fellowship based at Lyell McEwin Hospital and developed and leads an electrophysiology research program based around these clinical services. Thus far, he has amassed a dedicated research team that currently consists of an academic staff, two research staff and HDR students.

A/Prof Mahajan is an invited reviewer for several peer-reviewed journals and currently serving on the editorial board of Journal of Cardiac Electrophysiology and Heart Rhythm Case Reports (Heart Rhythm Society, USA). He was an invited speaker at several international and national conferences including invites to world renowned societies (HRS, ESC, Asia Pacific HRS, CSANZ). He has co-authored the guidelines on behalf of the Heart Rhythm Council of the Cardiac Society of Australia and New Zealand (CSANZ and the European Cardiac Society (ESC). He has published chapters in important cardiac electrophysiology textbooks including Cardiac Electrophysiology: From Cell to Bedside, Zipes DP (Ed) (2017). A/Prof Mahajan has over 135 publications in peer review top cardiology journals.

He has a particular interest in precision health and risk factors for atrial fibrillation and interventions aimed at improving outcomes of patients with this common heart rhythm disorder. In addition, he is interested in investigating the potential ways that can reduce the burden of AF related stroke in the general population.

Obesity and AF: His initial research has focussed on the risk factors for atrial fibrillation (in particular obesity). He has undertaken key translational and clinical studies that have produced new information on the mechanism by which obesity predisposes to AF and how its management results in improvement in clinical outcomes. These have been incorporated in national and international AF guidelines. He is now investigation a precision health platform in AF.

Subclinical AF and cognitive impairment: Dr Mahajan's recent focus has been on the impact of subclinical AF on stroke and have published a well cited meta-analysis on the association. He is investigating the association of AF and dementia and evaluating the role in AF screening and whether treatment of subclinical AF may have an impact on dementia in the community.

 

Research Projects Available

Project 1 - COGSaFe

Project description - AF is a heart rhythm disorder which is associated with a 40% increased risk of dementia. AF can be asymptomatic and intermittent in the early course of the disease and thereby remains undetected and untreated during this phase. AF leads to formation of blood clots in the heart. The chances of the formation of blood clots in the heart is dependent on the comorbid conditions and age. These clots break away and migrate to the brain leading to both silent and symptomatic brain infarction. These silent infarctions culminate into cognitive impairment. We are currently investigating the relationship between AF and Cognitive impairment in subclinical AF.

Location: University Precinct, Lyell McEwin Hospital and University of Adelaide

 

Project 2 - Precision AF

Project description - In this MRFF funded project, we develop a scalable precision health platform as an alternative to conventional management of patients with AF. 

Location: University Precinct, Lyell McEwin Hospital and University of Adelaide

 

Project 3- RECORD AF Cohort Study 

Project description - In this database, we collect longitudinal data on patients with AF with aim to assess health literacy, shared decision making and medical data with the aim to answer several un-answered questions in real world scenario. 

Location: University Precinct, Lyell McEwin Hospital and University of Adelaide
