Christodoulos I. Stefanadis

Christodoulos I. Stefanadis is Professor of Cardiology in the Medical School of the University of Athens. Some of his main research interests include coronary heart disease, detection and treatment of vulnerable atheromatic plaque, aortic elastic properties, mitral valve disease, interventional treatment of resistant hypertension and designing many catheter types used for various diagnostic and therapeutic interventional procedures.^[1]

Biography

Christodoulos Stefanadis was born in Ikaria, Greece and attended the University of Athens Medical School from which he graduated in 1971. He completed his residency in Cardiology at the Cardiology Department of the University of Athens (1978), followed by a PhD in Athens Medical School (1981). He has been Professor of Cardiology since 2002 and Director of the 1st Department of Cardiology since 2003.^[2] He has held the positions of Dean of Athens Medical School (2007-2011), President of the Hellenic Society of Cardiology (1997-1999 & 2007-2009), Board Member of the Hellenic Heart Foundation (1995–present),^[3] Professor of Medicine, Department of Medicine, Division of Cardiology, Emory University, Atlanta U.S.A.,^[4] Professor of Internal Medicine, Cardiology, Yale University, New Haven, Connecticut, USA (July 2014-)^[5]

Research

One of his several research activities include designing of at least 10 prototype cardiac catheters which were applied in various diagnostic and therapeutic interventions. Early in his career he developed the technique of retrograde non-transeptal mitral balloon valvuloplasty which has been used internationally for the interventional treatment of mitral stenosis, introduced the idea of covering metallic stents by non-thrombotic material and he developed covered stents by autologous vascular (arterial or vein) grafts. He subsequently made studies on the elastic properties of aorta and the function of left atrium. A large part of his research efforts was devoted to experimental and clinical studies on coronary heart disease, such as estimation of thermal heterogeneity of human atherosclerotic plaques using a special catheter with a thermistor tip, external non-invasive heating of stented arterial segments, and evolution and application of bevacizumab-eluting stent for the inhibition of microvessel growth in unstable atherosclerotic plaques.^[6] He has been worked lately on invasive treatment methods of resistant hypertension by novel sympathetic denervation techniques of the renal arteries (chemical denervation, barodenervation).^[7] He has presented his research results by more than 3,500 abstracts in international scientific conferences and has given over 260 lectures as invited speaker internationally.

Publications

Stefanadis has published 1336 (as of June, 2014) research articles in international peer reviewed medical journals.^[8] The h-index factor for these publications is 62.^[9] He is the editor of 6 medical books of international publications and has written chapters in 13 international books. He is Chief Editor of the Hellenic Journal of Cardiology,^[10] and member of the editorial board and reviewer in Greek and International Scientific Journals.

Honors and awards

Stefanadis was awarded the title of "Elite Reviewer" by the scientific journal Journal of the American College of Cardiology (JACC) in recognition of his whole contribution to the journal’s publications (2005)^[11] and the international journal Clinical Cardiology dedicated a special honorary article to him entitled "Profiles in Cardiology" in a 2007 issue.^[12]

The American College of Cardiology awarded him the Simon Dack’s Award (2011), which is given annually to the scientist with the most important contribution to the scientific journals of the American College of Cardiology (Journal of the American College of Cardiology, JACC-Cardiovascular Interventions and JACC-Cardiovascular Imaging).^[13]
