MI and stroke risks early after COPD exacerbation

---are increased:

There was a 2.27-fold (95% CI, 1.1-4.7; P = .03) increased risk of MI 1 to 5 days after exacerbation (defined by prescription of both steroids and antibiotics). This relative risk diminished progressively with time and was not significantly different from the baseline MI risk at any other postexacerbation time interval. One in 2,513 exacerbations was associated with MI within 1 to 5 days. There was a 1.26-fold (95% CI, 1.0-1.6; P = .05) increased risk of stroke 1 to 49 days after exacerbation.

Conclusion: The results suggest that exacerbations of COPD increase the risk of MI and stroke. This may have implications for therapy in both stable and exacerbated COPD.
