Implication
Smoking confers no post-PCI benefit after age adjustment; challenges smokers' paradox and supports confounding-adjusted analyses in future cohorts.
Structured PICO
Does smoking status affect cardiovascular outcomes in patients following percutaneous coronary intervention?
P
Population
Patients who underwent percutaneous coronary intervention (PCI) at a single US Veterans Administration hospital from 2004 to 2009
I
Intervention
Active smoking status
C
Comparator
Non-smoking status
O
Outcome
Composite of myocardial infarction, unplanned coronary intervention, unplanned cardiac hospitalization, and death at 6 months after PCIcomposite
The study debunks the 'smokers' paradox' in PCI patients, demonstrating that the apparent protective effect of smoking on cardiovascular outcomes is entirely confounded by the younger age of smokers.
