Download2008
Humphries, K., Norris, C.M., Quan, H., Galbraith, P.D., Southern, D.A., Gao, M., Knudtson, M.L., Ghali, W.A., Shrive, F.M.
Background: We have previously described a method for dealing with missing data in a prospective cardiac registry initiative. The method involves merging registry data to corresponding ICD-9-CM administrative data to fill in missing data 'holes'. Here, we describe the process of translating our...

Effect of obesity on short- and long-term mortality postcoronary revascularization: a meta-analysis.
Download2008
Kalantar-Zadeh, K., Mullen, J.C., Pretorius, V., Padwal, R., Oreopoulos, A., Norris, C.M.
Objective: Overweight and obesity are often assumed to be risk factors for postprocedural mortality in patients with coronary artery disease (CAD). However, recent studies have described an “obesity paradox”—a neutral or beneficial association between obesity and mortality postcoronary...

Functional outcomes after neonatal open cardiac surgery: comparison of survivors of the Norwood staged procedure and the arterial switch operation
Download2010
Robertson, C., Alton, G., Rempel, G., Newburn-Cook, C., Norris, C.M.
Background: Improvements in long-term survival of children undergoing the Norwood staged procedure and the arterial switch operation have resulted in the need to prepare these at-risk children for each stage of their developmental trajectory, including school readiness. This study describes and...

Background. It has been suggested that the routine use of statins preoperatively would reduce the risk of postoperative infection. We conducted this study to explore whether preoperative statin use was associated with infection after cardiac surgery (recipients of which have a higher-than-average...

Risk-taking attitides and their association with process and outcomes of cardiac care: a cohort study
Download2009
Ghali, W.A., Knudtson, M.L., King, K.M., Norris, C.M.
Background: Prior research reveals that processes and outcomes of cardiac care differ across sociodemographic strata. One potential contributing factor to such differences is the personality traits of individuals within these strata. We examined the association between risk-taking attitudes and...

Tonelli, M., Ezekowitz, J., Ghali, W.A., Humphries, K.H., Norris, C.M., McAlister, F. A., Knudtson, M.L.
Objectives This study was designed to examine the use of cardiovascular medications and outcomes in patients with heart failure (HF) and renal dysfunction. Background Renal insufficiency is associated with poorer outcomes in patients with HF, but the mechanisms are uncertain. In particular,...
