Stress CMR as a measure to separate athletic hearts from early dilated cardiomyopathies

Rojda Ipek, Jennifer L. Holland, Roshan Xavier, Per Arvidsson et autres

Motivation: Exercise-induced cardiac adaptations can manifest as left ventricular (LV) dilatation and mildly reduced LV ejection fraction (LVEF), which makes the differentiation of an athletic heart from early dilated cardiomyopathy (DCM) challenging. This overlap of clinical uncertainty is termed 'grey zone' being …

Exercise CMR and proteomic characterization of HFpEF across the spectrum of LV ejection fraction

Roshan Xavier, Sher May Ng, Jiliu Pan, Per Arvidsson et autres

Background: Heterogeneity within heart failure with preserved ejection fraction (HFpEF) is poorly understood and hinders the development of new therapies for this condition. Despite comparable symptom burden, clinical trials suggest differential treatment responses between HFpEF patients with resting LV ejection fraction above …

IRON-HEART: Cardiac and skeletal muscle energetics in chronic heart failure and iron deficiency

Sarah Birkhoelzer, Per Arvidsson, Jordan McGing, Mehrsa Jafarpour et autres

Motivation: Determining the impact of iron repletion on muscle energetics in non-ischaemic cardiomyopathy with reduced ejection fraction (EF). Goal(s): Use cardiac and skeletal muscle 31P MRS to assess cardiac and skeletal muscle energetics pre and post iron repletion therapy. Approach: Participants and …

Investigating myocardial energetic deficit across the spectrum of cardiac disease

John A. Henry, E Levelt, J J Rayner, Moritz Hundertmark et autres

Abstract Introduction The phosphocreatine-to-adenosine triphosphate ratio (PCr/ATP) is a sensitive marker of the energetic state of the heart and can be reliably measured non-invasively using 31Phosphorus magnetic resonance spectroscopy (31P-MRS). Derangements in cardiac energetics are a distinctive feature in the pathophysiology of …

Invasive validation of pressure-volume loops derived from cardiovascular magnetic resonance imaging and brachial blood pressure in heart failure patients

Per Arvidsson, P G Green, W. D. Watson, Mayooran Shanmuganathan et autres

Abstract Introduction Left ventricular (LV) pressure-volume (PV) loops provide gold-standard physiological information but require invasive measurements of ventricular intracavity pressure, limiting clinical and research applications. Recent development has seen the introduction of non-invasively computed PV loops from cardiovascular magnetic resonance (CMR) volumetry …
