Mitochondrial morphology is shaped by fusion and division of their membranes. Here, we found that adult myocardial function depends on balanced mitochondrial fusion and fission, maintained by processing of the dynamin-like guanosine triphosphatase OPA1 by the mitochondrial peptidases YME1L and OMA1. Cardiac-specific ablation of Yme1l in mice activated OMA1(More)
BACKGROUND The circadian clock influences a number of cardiovascular (patho)physiological processes including the incidence of acute myocardial infarction. A circadian variation in infarct size has recently been shown in rodents, but there is no clinical evidence of this finding. OBJECTIVE To determine the impact of time-of-day onset of ST segment(More)
To commemorate the auspicious occasion of the 30th anniversary of IPC, leading pioneers in the field of cardioprotection gathered in Barcelona in May 2016 to review and discuss the history of IPC, its evolution to IPost and RIC, myocardial reperfusion injury as a therapeutic target, and future targets and strategies for cardioprotection. This article(More)
BACKGROUND Spain, a Mediterranean country with relatively low rates of coronary heart disease, has a high prevalence of traditional cardiovascular risk factors and is experiencing a severe epidemic of overweight/obesity. We designed the Aragon Workers' Health Study (AWHS) to characterize the factors associated with metabolic abnormalities and subclinical(More)
Recombinant-ApoA-I(M) (rApoA-I(M)) administration has been shown to regress and stabilize atherosclerotic plaques. However, the mechanisms responsible for these beneficial effects are not fully understood. The aims of the present study were to define whether the benefits of rApoA-I(M) treatment were mediated via an enhanced reverse cholesterol transport(More)
BACKGROUND In-vivo quantification of cardiac perfusion is of great research and clinical value. The dual-bolus strategy is universally used in clinical protocols but has known limitations. The dual-saturation acquisition strategy has been proposed as a more accurate alternative, but has not been validated across the wide range of perfusion rates encountered(More)
Myocardial fibrosis detected via delayed-enhanced magnetic resonance imaging (MRI) has been shown to be a strong indicator for ventricular tachycardia (VT) inducibility. However, little is known regarding how inducibility is affected by the details of the fibrosis extent, morphology, and border zone configuration. The objective of this article is to(More)
Two authors' names were omitted from the original article, Natalia Trayanova and Michael Miller. The affiliations of Drs. Trayanova and Miller are listed in the amended author list above. The labs of Drs. Trayanova and Miller jointly developed the method used in the original paper to estimate the fiber orientations in each patient's heart. 1 Some fiber(More)
To the Editor: After an acute myocardial infarction (AMI), infarct size quantification is of clinical importance because it correlates with postinfarction mortality and morbidity (1). The gold standard in vivo techniques for infarct size quantification are magnetic resonance imaging and single-photon emission computed tomog-raphy; however, these methods are(More)
INTRODUCTION Decreased plasma vitamin D (VD) levels are linked to cardiovascular damage. However, clinical trials have not demonstrated a benefit of VD supplements on left ventricular (LV) remodelling. Anterior ST-elevation acute myocardial infarction (STEMI) is the best human model to study the effect of treatments on LV remodelling. We present a(More)
