Body mass index and mortality in heart failure: a meta-analysis.
Antigone Oreopoulos,Raj Padwal,Kamyar Kalantar-Zadeh,Gregg C. Fonarow,Colleen M. Norris,Finlay A. McAlister +5 more
TL;DR: Overweight and obesity were associated with lower all-cause and cardiovascular mortality rates in patients with CHF and were not associated with increased mortality in any study.
Journal ArticleDOI

Louise Pilote,Kaberi Dasgupta,Veena Guru,Karin H. Humphries,Jennifer J. McGrath,Colleen M. Norris,Doreen M. Rabi,Johanne Tremblay,Arsham Alamian,Tracie A. Barnett,Jafna L. Cox,William A.

TL;DR: The lack of good trial evidence concerning sex-specific outcomes has led to assumptions about CVD treatment in women, which may have resulted in inadequate diagnoses and suboptimal management, greatly affecting outcomes, and may also explain why cardiovascular health in women is not improving as fast as that of men.
Journal ArticleDOI
An administrative data merging solution for dealing with missing data in a clinical registry: adaptation from ICD-9 to ICD-10
Danielle A. Southern,Colleen M. Norris,Hude Quan,Fiona M. Shrive,P. Diane Galbraith,Karin H. Humphries,Karin H. Humphries,Min Gao,Min Gao,Merril L. Knudtson,William A. Ghali +10 more
TL;DR: ICD-10 implementation of the data merging method performs as well as the previously-validated ICD-9-CM method, and is an essential prerequisite for research with administrative data now that most health systems are transitioning to I CD-10.
Journal ArticleDOI
The association among renal insufficiency, pharmacotherapy, and outcomes in 6,427 patients with heart failure and coronary artery disease.
Justin A. Ezekowitz,Finlay A. McAlister,Karin H. Humphries,Colleen M. Norris,Marcello Tonelli,William A. Ghali,Merril L. Knudtson,Approach Investigators +7 more
TL;DR: Renal insufficiency is common in patients with HF and coronary artery disease, and these patients have more advanced coronary atherosclerosis, and they are less likely to be prescribed efficacious therapies, but have better outcomes if they receive these medications.
Journal ArticleDOI
Survival After Coronary Revascularization in the Elderly
Michelle M. Graham,William A. Ghali,Peter Faris,P. Diane Galbraith,Colleen M. Norris,Merril L. Knudtson +5 more
TL;DR: Elderly patients with ischemic heart disease are increasingly referred for coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) and reports of poor outcomes in the elderly have led to questions about the benefit of these strategies.
