Cerebrovascular accident (CVA) is one of the leading causes of death in the United States. Von Willebrand factor plays an important role in platelet activation and adhesion. It remains unclear whether Von Willebrand disease (vWD) is associated with a decreased risk of developing CVA. ⋯ This suggests that deficiency of Von Willebrand factor is potentially protective against the development of CVA. To the best of our knowledge, this is the first study in humans to compare the RR of CVA in patients with and without vWD. Future studies are needed to explore causal relationships and therapeutic benefits.

We examined individual and joint associations among high-sensitivity C-reactive protein (CRP), cardiorespiratory fitness (fitness), and mortality in healthy men and women. Between January 1, 2000 and December 31, 2016, 30,077 adults (31.3% women) received a comprehensive physical examination. Fitness was determined from maximal treadmill exercise test duration. ⋯ Each 1 metabolic equivalent increment in fitness and 1 mg/L increment in CRP were associated with 10.0% (95% CI: 5.1-14.8%) decreased and 7.3% (95% CI: 2.0%-12.9%) increased mortality hazard, respectively. Compared to the unfit, fit individuals have an attenuated mortality risk within each CRP category. Thus, higher fitness appears to provide some protection against all-cause mortality, particularly among those with elevated levels of inflammation.
