Impaired coronary blood flow at higher heart rates during atrial fibrillation: Investigation via multiscale modelling
Sign Up to like & getrecommendations! Published in 2019 at "Computer methods and programs in biomedicine"
DOI: 10.1016/j.cmpb.2019.04.009
Abstract: BACKGROUND Different mechanisms have been proposed to relate atrial fibrillation (AF) and coronary flow impairment, even in absence of relevant coronary artery disease (CAD). However, the underlying hemodynamics remains unclear. Aim of the present work… read more here.

Autoregulation of Coronary Blood Supply in Response to Demand: JACC Review Topic of the Week.
Sign Up to like & getrecommendations! Published in 2021 at "Journal of the American College of Cardiology"
DOI: 10.1016/j.jacc.2021.03.293
Abstract: Although our coronary circulation evolved to meet demands during marked physical exertion for "fight or flight" survival, complex and multilayered control mechanisms reduce flow during other periods. Understanding homeostasis of resting flow provides essential insights… read more here.

DOI: 10.1080/00365513.2018.1455220
Abstract: Abstract Dual antiplatelet therapy is recommended in patients undergoing primary percutaneous coronary intervention (p-PCI) for ST-segment elevation myocardial infarction (STEMI). Pre-analytical variables may influence platelet function analysis results. Our aim was to evaluate the on-treatment… read more here.

Alterations in Coronary Blood Flow and the Risk of Left Ventricular Distension in Venoarterial Extracorporeal Membrane Oxygenation
Sign Up to like & getrecommendations! Published in 2023 at "ASAIO Journal"
DOI: 10.1097/mat.0000000000001905
Abstract: Previous theoretical studies have suggested that veno-arterial extracorporeal membrane oxygenation (VA-ECMO) ought to consistently result in markedly increased left ventricular (LV) intracavitary pressures and volumes because of increased LV afterload. However, this phenomenon of LV… read more here.

DOI: 10.1152/japplphysiol.01046.2017
Abstract: Peripheral arterial disease (PAD) is associated with augmented blood pressure (BP) and impaired coronary blood flow responses to exercise, which may increase cardiovascular risk. We investigated the effects of leg revascularization on the BP and… read more here.
