..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...

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

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

..We sought to establish the long-term safety of drug-eluting stents compared with bare-metal stents in a usual care setting...

..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...

..It is unknown if coronary dominance has an impact on prognosis of these patients. We hypothesized that the prognosis of patients with ACS with left dominance (LD) would be worse than that of patients with right or mixed dominance...

..Surnames have the potential to accurately identify ancestral origins as they are passed on from generation to generation. In this study, we developed and validated a Chinese surname list to define Chinese ethnicity...

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

..8 ml/min following moderate to severe acute kidney injury. Thus, acute kidney injury following coronary angiography is associated with a sustained loss and a larger rate of future decline in kidney function...

..73 m(2). These findings provide considerable refinement in our understanding of eGFR as a powerful prognostic marker in patients with CVD undergoing cardiac catheterization...

..We examined the 1-year incidence of HF and its association with mortality among patients surviving their first acute coronary syndrome (ACS) hospitalization...

..These prediction rules can be useful for risk-adjustment analyses and for prognostication for individual patients...

..The purpose of this study was to evaluate the effect of chelation therapy with ethylenediamine tetraacetic acid (EDTA) on endothelium-dependent vasomotor responses in patients with documented coronary artery disease (CAD)...

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

..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 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...

..This study examines the use of an existing database to gain further insights into the relationship between geography and access to cardiac care, and the distance-access relationship for coronary revascularization in Alberta...

....

..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...

....

..Several issues that decision-makers and providers may wish to consider when making such funding decisions are discussed...

..Despite this, both income measures appear to be prognostically relevant, perhaps because individual and neighborhood income measure different constructs...

..There is an ongoing need to continually reassess current risk stratification methods to limit adverse events in patients on waiting lists and assist clinicians in triaging patients for invasive therapies...

..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...
