Coronary disease & ACSCohort study
Risk of Death in Patients With Coronary Artery Disease Taking Nitrates and Phosphodiesterase-5 Inhibitors
- Retrospective cohort study
- nationwide registers (Swedish Patient Register, Prescribed Drug Register)
- multivariable Cox regression
Authors' conclusion
The use of a PDE5i in combination with nitrate medication in men with stable coronary artery disease may pose an increased hazard for cardiovascular morbidity and mortality.
Study context
- Population
- Men with stable CAD (previous myocardial infarction (MI) or revascularization, 2006–2013) treated with nitrates, Sweden
- Participants
- 5,710 vs 55,777
- Exposure
- PDE5i + nitrates vs nitrates alone
- Nitrates + PDE5in = 5,710
- Nitratesn = 55,777reference
- Outcome
- CV outcomes: all-cause, CV and non-CV mortality, MI, HF, cardiac revascularization, major cardiovascular events (MACE)
