Dr Antonio de Marvao is a Clinical Senior Lecturer in the Department of Women and Children’s Health and in the School of Cardiovascular and Metabolic Medicine & Sciences at King's College London. Clinically, he works as a Consultant Cardiologist, specialising in Inherited Cardiac Conditions (ICC), and as an Obstetric Physician, with a special interest in Maternal Cardiology and Hypertension in Pregnancy. His clinics are at St Thomas' and King's College Hospitals.

Antonio graduated from the University of Glasgow in 2007 and went on to complete his Foundation training in Scotland. In 2009 he moved to London, where he undertook his core medical training across Hammersmith, Charing Cross and St. Mary’s hospitals. Antonio was appointed to specialty training in Cardiology and General Internal Medicine in 2011 and in 2012 awarded an MRC Chain-Florey Clinical Research Fellowship to undertake a PhD. His early training in Cardiology at Hammersmith Hospital was complemented by advanced fellowships in Cardiac CT, CMR and Inherited Cardiovascular Conditions at the Royal Brompton Hospital. Between 2016 and 2021 he was an MRC Chain-Florey Clinical Lecturer in Cardiology at Imperial College London. Antonio completed his dual training with a senior fellowship in Obstetric Medicine at St Thomas' Hospital in 2021/22. During his training, Antonio developed a clinical and academic interested in Maternal Cardiology, particularly in the management of hypertensive disorders, heart failure and cardiomyopathies during pregnancy.

His research group at KCL aims to understand the genomic and physiological underpinnings of cardiovascular dysfunction in pregnancy, in particular gestational hypertension, preeclampsia and heart failure, and its impact on maternal and fetal health. The team makes use of genomic data, deep maternal and fetal cardiovascular phenotyping and machine learning analysis of longitudinal population-scale clinical data, to characterise the biological pathways that lead to healthy cardiovascular adaption in pregnancy or to pathological remodelling. This offers the potential for improved risk stratification, personalised management strategies and targeted therapies, not only during pregnancy but during the life course of cardiovascular disease.

His work has been supported by research grants from the Fetal Medicine Foundation, British Heart Foundation, Mason Medical Research Foundation, Academy of Medical Sciences and the Medical Research Council.
