Relationship between left ventricular structural and metabolic remodeling in type 2 diabetes

E Levelt, M Mahmod, SK Piechnik, R Ariga… - Diabetes, 2016 - Am Diabetes Assoc
Concentric left ventricular (LV) remodeling is associated with adverse cardiovascular events
and is frequently observed in patients with type 2 diabetes mellitus (T2DM). Despite this, the …

Ectopic and visceral fat deposition in lean and obese patients with type 2 diabetes

…, M Mahmod, C Kelly, J Sellwood, R Ariga… - Journal of the American …, 2016 - jacc.org
Background : Type 2 diabetes (T2D) and obesity are associated with nonalcoholic fatty liver
disease, cardiomyopathy, and cardiovascular mortality. Both show stronger links between …

Cardiac energetics, oxygenation, and perfusion during increased workload in patients with type 2 diabetes mellitus

…, WT Clarke, M Mahmod, R Ariga… - European heart …, 2016 - academic.oup.com
Aims Patients with type 2 diabetes mellitus (T2DM) are known to have impaired resting
myocardial energetics and impaired myocardial perfusion reserve, even in the absence of …

Progression of myocardial fibrosis in hypertrophic cardiomyopathy: mechanisms and clinical implications

B Raman, R Ariga, M Spartera… - European Heart …, 2019 - academic.oup.com
Aims Myocardial fibrosis as detected by late gadolinium enhancement (LGE) on cardiac
magnetic resonance (CMR) is a powerful prognostic marker in hypertrophic cardiomyopathy (…

Identification of myocardial disarray in patients with hypertrophic cardiomyopathy and ventricular arrhythmias

R Ariga, EM Tunnicliffe, SG Manohar… - Journal of the American …, 2019 - jacc.org
Background : Myocardial disarray is a likely focus for fatal arrhythmia in hypertrophic
cardiomyopathy (HCM). This microstructural abnormality can be inferred by mapping the …

[HTML][HTML] Distinct ECG phenotypes identified in hypertrophic cardiomyopathy using machine learning associate with arrhythmic risk markers

A Lyon, R Ariga, A Mincholé, M Mahmod… - Frontiers in …, 2018 - frontiersin.org
Aims: Ventricular arrhythmia triggers sudden cardiac death (SCD) in hypertrophic cardiomyopathy
(HCM), yet electrophysiological biomarkers are not used for risk stratification. Our aim …

[HTML][HTML] Adenosine stress CMR T1-mapping detects early microvascular dysfunction in patients with type 2 diabetes mellitus without obstructive coronary artery …

…, A Liu, RS Wijesurendra, M Mahmod, R Ariga… - Journal of …, 2016 - Elsevier
Background Type 2 diabetes mellitus (T2DM) is associated with coronary microvascular
dysfunction in the absence of obstructive coronary artery disease (CAD). Cardiovascular …

Lone atrial fibrillation is associated with impaired left ventricular energetics that persists despite successful catheter ablation

RS Wijesurendra, A Liu, C Eichhorn, R Ariga, E Levelt… - Circulation, 2016 - Am Heart Assoc
Background: Lone atrial fibrillation (AF) may reflect a subclinical cardiomyopathy that persists
after sinus rhythm (SR) restoration, providing a substrate for AF recurrence. To test this …

[HTML][HTML] The interplay between metabolic alterations, diastolic strain rate and exercise capacity in mild heart failure with preserved ejection fraction: a cardiovascular …

…, B Raman, S Dass, E Levelt, R Ariga… - Journal of …, 2018 - Elsevier
Background Heart failure (HF) is characterized by altered myocardial substrate metabolism
which can lead to myocardial triglyceride accumulation (steatosis) and lipotoxicity. However …

[HTML][HTML] MRI-based computational torso/biventricular multiscale models to investigate the impact of anatomical variability on the ECG QRS complex

A Mincholé, E Zacur, R Ariga, V Grau… - Frontiers in …, 2019 - frontiersin.org
Aims Patient-to-patient anatomical differences are an important source of variability in the
electrocardiogram, and they may compromise the identification of pathological …
