Stroke Risk Following Perioperative Atrial Fibrillation—Reply
In Reply Dr Kurlansky raises a concern about the positive predictive value of diagnosis codes used to identify perioperative AF in our study of the long-term risk of stroke associated with this condition. Two separate issues should be considered in this regard.

Percutaneous Left Atrial Appendage Closure vs Warfarin for Atrial Fibrillation A Randomized Clinical Trial
Conclusions and RelevanceAfter 3.8 years of follow-up among patients with nonvalvular AF at elevated risk for stroke, percutaneous LAA closure met criteria for both noninferiority and superiority, compared with warfarin, for preventing the combined outcome of stroke, systemic embolism, and cardiovascular death, as well as superiority for cardiovascular and all-cause mortality.Trial Registrationclinicaltrials.gov Identifier: NCT00129545

Progress Against Cardiovascular Disease Putting the Pieces Together
The JAMA theme issue on cardiovascular disease (CVD) recognizes the progress made in CVD but also acknowledges the challenges that remain. On the positive side, from 2000 to 2010 age-adjusted death rates attributable to overall CVD in the United States declined by more than 30%. Yet CVD continued to account for a third (787 650) of the 2.5 million deaths in the United States per year, an average of 1 death every 40 seconds. Worldwide, the picture is more concerning. The incidence of CVD is increasing rapidly in low- or-moderate income countries, and according to current World Health Organization statistics, ischemic hear...

Time Since Stroke and Risk of Adverse Outcomes After Surgery—Reply
In Reply Dr Powers asks whether surgery actually increased the risk of recurrent stroke or whether recurrent stroke would have occurred at comparable rates among patients not undergoing surgery. As highlighted by Powers, the natural course of stroke includes a time-dependent decline in risk of recurrent stroke also among patients not undergoing surgery.

Time Since Stroke and Risk of Adverse Outcomes After Surgery
To the Editor Dr Jørgensen and colleagues reported an increased risk of recurrent stroke within 30 days after surgery in patients with previous stroke compared with those without previous stroke and that the risk was higher the closer to the incident stroke that the surgery was performed. However, this study cannot be interpreted as showing that the risks of surgery are greater if performed closer to the incident stroke because it lacks a crucial control group with recent stroke who did not undergo surgery.
