Using aspirin for coronary heart disease prevention is less costly and more effective, found in a study.
For the study, researchers at RTI International, University of Michigan, and University of North Carolina at Chapel Hill used a Markov model to compare the costs and outcomes of prescribing low-dose aspirin alone, aspirin plus a proton-pump inhibitor, or no treatment for coronary heart prevention.
AdvertisementThe researchers specifically considered the effects of each treatment on cardiovascular events and risk of upper gastrointestinal bleeding.
"This analysis supports the role of aspirin for primary prevention of cardio heart disease events in middle-aged men across a range of cardio heart disease and gastrointestinal bleeding risk levels," said lead author Stephanie Earnshaw, of the RTI Health Solutions.
"Increased risk of gastrointestinal bleeding does not reduce aspirin's net benefit until gastrointestinal bleeding risk becomes quite high," she said.
The researchers also found that adding proton pump inhibitors was not cost-effective for men with average gastrointestinal tract bleeding, but may be cost-effective for selected men at increased risk for gastrointestinal bleeding.
The findings have been published in the Archives of Internal Medicine.
