Journal ArticleDOI
Association of fibrosis with mortality and sudden cardiac death in patients with nonischemic dilated cardiomyopathy.
Ankur Gulati,Andrew Jabbour,Tevfik F Ismail,Kaushik Guha,Jahanzaib Khwaja,Sadaf Raza,Kishen Morarji,Tristan D.H. Brown,Nizar Ismail,Marc R. Dweck,Elisa Di Pietro,Michael Roughton,Ricardo Wage,Yousef Daryani,Rory O'Hanlon,Mary N. Sheppard,Francisco Alpendurada,Alexander R. Lyon,Stuart A. Cook,Martin R. Cowie,Ravi Assomull,Dudley J. Pennell,Sanjay K Prasad +22 more
TL;DR: Risk stratification of patients with nonischemic dilated cardiomyopathy is primarily based on left ventricular ejection fraction (LVEF), and superior prognostic factors may improve patient selection for implantable cardioverter-defibrillators (ICDs) and other management decisions.
Journal ArticleDOI
Midwall Fibrosis Is an Independent Predictor of Mortality in Patients With Aortic Stenosis
Marc R. Dweck,Sanjiv Joshi,Timothy Murigu,Francisco Alpendurada,Andrew Jabbour,Giovanni Melina,Winston Banya,Ankur Gulati,Isabelle Roussin,Sadaf Raza,Nishant A. Prasad,Rick Wage,Cesare Quarto,Emiliano Angeloni,Simone Refice,Mary N. Sheppard,Stuart A. Cook,Philip J. Kilner,Dudley J. Pennell,David E. Newby,Raad H. Mohiaddin,John Pepper,Sanjay K Prasad +22 more
TL;DR: Midwall fibrosis was an independent predictor of mortality in patients with moderate and severe aortic stenosis and has incremental prognostic value to ejection fraction and may provide a useful method of risk stratification.
Journal ArticleDOI
The Prevalence and Prognostic Significance of Right Ventricular Systolic Dysfunction in Nonischemic Dilated Cardiomyopathy
Ankur Gulati,Tevfik F Ismail,Andrew Jabbour,Francisco Alpendurada,Kaushik Guha,Nizar Ismail,Sadaf Raza,Jahanzaib Khwaja,Tristan D.H. Brown,Kishen Morarji,Emmanouil Liodakis,Michael Roughton,Ricardo Wage,Tapesh Pakrashi,Rakesh Sharma,John-Paul Carpenter,Stuart A. Cook,Martin R. Cowie,Ravi Assomull,Dudley J. Pennell,Sanjay K Prasad +20 more
TL;DR: Cardiovascular magnetic resonance assessment of RV function is important in the evaluation and risk stratification of DCM patients and is a powerful, independent predictor of transplant-free survival and adverse heart failure outcomes in DCM.
Journal ArticleDOI
Role of late gadolinium enhancement cardiovascular magnetic resonance in the risk stratification of hypertrophic cardiomyopathy
Tevfik F Ismail,Andrew Jabbour,Ankur Gulati,Amy Mallorie,Sadaf Raza,Thomas E Cowling,Bibek Das,Jahanzaib Khwaja,Francisco Alpendurada,Ricardo Wage,Michael Roughton,William J. McKenna,James C. Moon,Amanda Varnava,Carl Shakespeare,Martin R. Cowie,Stuart A. Cook,Perry M. Elliott,Rory O'Hanlon,Dudley J. Pennell,Sanjay K Prasad +20 more
TL;DR: The amount of myocardial fibrosis was a strong univariable predictor of SCD risk, however, this effect was not maintained after adjusting for LV-EF and non-sustained ventricular tachycardia.
Journal ArticleDOI
Clinical utility and prognostic value of left atrial volume assessment by cardiovascular magnetic resonance in non-ischaemic dilated cardiomyopathy.
Ankur Gulati,Tevfik F Ismail,Andrew Jabbour,Nizar Ismail,Kishen Morarji,Aamir Ali,Sadaf Raza,Jahanzaib Khwaja,Tristan D.H. Brown,Emmanouil Liodakis,Arun J Baksi,Rameen Shakur,Kaushik Guha,Michael Roughton,Ricardo Wage,Stuart A. Cook,Francisco Alpendurada,Ravi Assomull,Raad H. Mohiaddin,Martin R. Cowie,Dudley J. Pennell,Sanjay K Prasad +21 more
TL;DR: This data indicates that left atrial volume predicts adverse outcome in small heart failure cohorts of mixed aetiology but the long‐term prognostic significance of LAV assessed by CMR in non‐ischaemic dilated cardiomyopathy is unknown.
