Potential effects of icosapent ethyl on cardiovascular outcomes in cigarette smokers: REDUCE-IT smoking
Authors' conclusion
In REDUCE-IT, IPE treatment was associated with a reduced risk of CV events in current and former smokers to levels observed in never smokers.
Study context
- Population
- Statin-treated patients with elevated TG and CV risk, by smoking history (current, former, never smokers)4,913 current or former smokers
- Participants
- 8,179 patients
- Comparison
- Icosapent ethyl vs placebo, by smoking history
- Primary endpoint
- Composite of:
- CV death
- Non-fatal MI
- Non-fatal stroke
- Coronary revascularization
- Hospitalization for unstable angina
- Follow-up
- Median 4.9 years
Methodological detailspost hoc, multinational, double-blind
- Post hoc
- Multinational
