Insights
Non-steroidal anti-inflammatory drug (NSAID) use has decreased in patients evaluated for coronary artery disease (CAD). However, NSAID use remains high in patients with severe CAD, indicating a need for continued monitoring and intervention.
Area of Science:
- Cardiology
- Pharmacology
- Public Health
Background:
- Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used for pain and inflammation.
- NSAID use has been associated with cardiovascular risks, including coronary artery disease (CAD).
- Understanding NSAID utilization patterns in patients undergoing CAD evaluation is crucial for risk stratification.
Purpose of the Study:
- To examine temporal trends in NSAID use among patients referred for suspected coronary artery disease (CAD).
- To assess NSAID prevalence based on CAD severity determined by diagnostic procedures.
Main Methods:
- A drug utilization study using population-based healthcare data from Western Denmark (3.3 million inhabitants).
- Three cohorts were defined by first-time diagnostic procedures for CAD assessment: coronary computed tomography angiography (CCTA), myocardial perfusion imaging (MPI), and invasive coronary angiography (ICA).
- One-year prevalence of NSAID use was calculated post-procedure, stratified by CAD severity.
Main Results:
- NSAID use declined over the study period (2008-2022) across all CAD severity levels for CCTA and ICA cohorts.
- In 2021, NSAID prevalence was 17% in severe CAD vs. 24% in no CAD (CCTA); 9% vs. 15% (MPI); and 10% vs. 20% (ICA).
- Despite the decline, NSAID use remained higher in patients without diagnosed CAD compared to those with severe CAD.
Conclusions:
- NSAID use has decreased among patients evaluated for CAD.
- NSAID use is lower in patients with CAD compared to those without CAD.
- NSAID use remains notably high in patients with severe CAD, necessitating further attention.
Purpose:
We examined temporal trends in NSAID use among patients referred for evaluation of suspected coronary artery disease (CAD).
Methods:
We conducted a drug utilisation study using population-based healthcare data from Western Denmark, covering 3.3 million inhabitants. Three cohorts were categorised based on first-time diagnostic procedure for CAD assessment: coronary computed tomography angiography (CCTA; 2008-2022, n = 91,230), myocardial perfusion imaging (MPI; 2016-2022, n = 17,044), and all invasive coronary angiograms (ICA; 2008-2022, n = 128,327). We calculated the one-year prevalence proportion of NSAID use after the diagnostic procedures, stratified by procedure-defined CAD severity.
Results:
NSAID use declined over the study period, regardless of CAD severity in patients undergoing CCTA or ICA (p < 0.001). In 2021, the one-year prevalence of NSAID use was 17% among patients with severe CAD vs. 24% among patients without CAD diagnosed using CCTA (prevalence proportion ratio [PPR] 0.73, 95% confidence interval [CI]: 0.60-0.90). In patients undergoing MPI, 9% of those with severe CAD vs. 15% of those with no CAD used NSAIDs (PPR 0.58, 95% CI: 0.45-0.73). In patients undergoing ICA, 10% of those with severe CAD and 20% of those with no CAD used NSAIDs (PPR 0.53, 95% CI: 0.44-0.62).
Conclusion:
Although NSAID use among patients with CAD has decreased and is lower than among patients without CAD, it remains relatively high in those with severe CAD.

Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
