The Relationship Between Cardiologist Care and Clinical Outcomes in Patients With New-Onset Atrial Fibrillation.

摘要: Abstract Background Increased mortality is well described in patients with atrial fibrillation (AF), primarily related to death from cardiovascular causes. One may hypothesize that cardiology care be associated a reduction deaths AF, thereby improving their overall survival. The aim of this study was assess the association between cardiologist and clinical outcomes, including all-cause mortality, new-onset AF. Methods This retrospective population-level, propensity score–matched cohort aged 20-80 years AF presenting an emergency department Ontario, Canada 2010 2012. Patients who saw within 1 year initial diagnosis were matched did not see cardiologist. Linked administrative databases used for construction allow 1-year follow-up end points death, hospitalization stroke syndromes, bleeding, heart failure. Results Cardiologist lower rate (5.3% vs 7.7%; hazard ratio, 0.68; 95% confidence interval, 0.55-0.84), despite increased hospitalizations (17.9% 8.2%), syndromes (1.7% 0.5%), bleeding (3.1% 2.0%), failure (3.2% 1.4%). Conclusions Further obtain greater understanding processes observed survival improvement warranted.
