..Here, we describe the process of translating our data merging solution to ICD-10, and then validating its performance...

..The purpose of this study was to identify the proportion of patients referred to CR in a large Canadian city, and to determine their statistically adjusted survival rates relative to patients not referred to CR...

..Anthropometric indices do not accurately reflect body composition in patients with CHF, especially in women. When accurate assessment of body composition is required, direct measurements should be obtained...

..The purpose of this study was to compare HRQOL outcomes of men and women in Alberta, at one-year following initial catheterization, after adjustment for known demographic, co-morbid, and disease severity predictors of outcome...

..This study was designed to examine whether discharge use of beta-blockers was associated with outcomes after hospitalization in patients who had undergone nontransplant cardiac surgery...

..HRQOL data were collected at 1 year following catheterization using the Seattle Angina Questionnaire (SAQ), a disease-specific quality of life and symptom rating scale...

..The results of this study suggest that both men and women report nontraditional prodromal symptoms of ACS. In addition, there appears to be a difference in the frequency and number of symptoms reported based on menopausal status...

..Accordingly, we compared symptoms, function, and QOL in SA and European Canadians with CAD using the Seattle Angina Questionnaire (SAQ)...

..We used population-level data to determine the rate at which such patients seek medical attention for these symptoms, whether sex differences are present, and if an association between prodromes and 1-year mortality exists...

..We examined the association between risk-taking attitudes and cardiac patients' clinical and demographic characteristics, the likelihood of undergoing invasive cardiac procedures and survival...

..The cause of the "treatment-risk paradox" reported for patients with coronary disease is unknown; however, determining the factors that contribute to this paradox is essential to properly design quality improvement interventions...

..CONCLUSION: In situations with competing risks, and where an analysis focuses on first events, the CICR method is most appropriate, as K-M methods will tend to overestimate event rates...

..The optimal population rate of cardiac catheterization is unknown. One potential way to determine it would be to examine whether there is a population rate beyond which the yield of high-risk coronary artery disease (CAD) does not rise...

..To describe health status outcomes at 4 years for a cohort of elderly patients with cardiac disease...

..Patients with obesity may be presenting earlier and receiving more aggressive treatment compared with those with normal BMI...

..The combination of these results with a recent randomized trial suggests that the benefits of aggressive revascularization therapies may extend to subsets of patients in older age groups...

..We sought to determine if such an age cutoff point exists...

..We evaluated the prognosis associated with diabetes, in analyses stratified by sex, to determine whether similar differences are seen in a large unselected cohort of patients...

..The potentially protective effect of increased BMI in CHF has been termed the obesity paradox or reverse epidemiology. This meta-analysis was conducted to examine the relationship between increased BMI and mortality in patients with CHF...

..In 2007, we introduced a policy to plan to extubate all patients after a modified Fontan procedure in the operating room. Our objective was to review the feasibility, safety, and clinical outcomes of this approach...

....

..We examined the validity of leg-to-leg bioelectrical impedance analysis (BIA) and near-infrared interactance (NIR) to assess body composition in chronic heart failure (CHF) patients...

..In addition, the need to adopt a longer-term view of risk in ACS patients is stressed, with particular regard to the important role of heart failure prediction and treatment...

..Depression has been shown to be strongly related to overall poorer outcomes in patients with coronary artery disease...

..The clinical correlates of coronary collaterals and the effects of coronary collaterals on prognosis are incompletely understood...

..We reviewed the effect of overweight and obesity systematically on short- and long-term all-cause mortality post-coronary artery bypass grafting (CABG) and post-percutaneous coronary intervention (PCI)...

..The aim of this study was to define the incidence, predictors, timing and clinical presentation of patients with ISR requiring repeat catheterization...

..Patients with renal insufficiency are less likely to be prescribed efficacious therapies, but have better outcomes if they receive these medications...

..This study compares the HRQOL outcomes of men and women in Alberta, Canada, 1 year after the documentation of coronary artery disease by cardiac catheterization...

....

..Both salivary cortisol level and the Hospital Anxiety and Depression Scale (HADS) are recognized measures of stress/anxiety and depression...

..Thus, it behooves health care providers to assess patients' levels of social support and intervene as appropriate...

..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 of postoperative infection)...

..The purpose of this study was to examine gender differences in depressive symptoms, as they relate to health-related quality of life outcomes following an AMI...

....

..This has potential to expand the donor pool. Pretransplant diabetes has a significant impact on long-term outcomes in cardiac transplantation and requires further investigation...

..EA-derived measures should therefore be used when individual data are not available...

..The trend toward a higher prevalence of malignancy in this unique patient group raises the possibility of malignancy-induced hypercoagulability or inflammation as an underlying etiologic factor...

..It is concluded that the choice of missing data strategy should be guided by statistical expertise and data resources...

..More data are needed before statins can be recommended in those with isolated heart failure...

..Although some studies suggest that access to cardiac procedures may differ by sex, others have found no evidence of gender bias in cardiac care...
