Trial summary

While the efficacy of aspirin for the secondary prevention of cardiovascular disease is evident, the effect of aspirin for primary prevention is unclear. The use of aspirin reduces cardiovascular mortality and myocardial infarction but increases side effects such as bleeding. Read more about this study

About this study

While the efficacy of aspirin for the secondary prevention of cardiovascular disease is evident, the effect of aspirin for primary prevention is unclear. The use of aspirin reduces cardiovascular mortality and myocardial infarction but increases side effects such as bleeding. Therefore, the use of aspirin for primary prevention in people without cardiovascular disease should be determined by individual risk and clinical benefit. The European guidelines have been changed to not recommend aspirin use in people without cardiovascular disease, but there are still people taking aspirin for primary prevention. The purpose of this study is to investigate the effect of aspirin withdrawal on cardiovascular events in patients without cardiovascular disease.

This is a single center, prospective, randomized clinical study evaluating the safety and efficacy of withdrawal of aspirin among patients with moderate or high cardiovascular risk.

Read the detailed description

Patients taking aspirin will be randomly assigned to a group that maintains taking aspirin and a group that discontinues to take aspirin by 1:1 manner. The follow-up duration is five years and clinical outcomes will be investigated.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Major adverse cardiovascular events(MACE)

    Major adverse cardiovascular events is composite endpoint. It includes cardiovascular death, nonfatal myocardial infarction, nonfatal ischemic stroke, coronary revascularization (percutaneous coronary intervention or coronary artery bypass graft), nonfatal ischemic stroke, and transient ischemic attack.

    Measured: 5 years

Secondary outcomes (6)
  1. cardiovascular death

    Individual component of primary endpoint

    Measured: 5 years

  2. nonfatal myocardial infarction

    Individual component of primary endpoint

    Measured: 5 years

  3. nonfatal ischemic stroke

  4. coronary revascularization

    Individual component of primary endpoint

    Measured: 5 years

  5. transient ischemic attack

    Individual component of primary endpoint

    Measured: 5 years

  6. Bleeding

    Major bleeding is defined with International Society on Thrombosis and Haemostasis (ISTH) criteria: 1) fatal bleeding; 2)Symptomatic bleeding in a critical area or organ, such as intracranial, intraspinal, intraocular, retroperitoneal, intraarticular or pericardial, or intramuscular with compartment syndrome; 3) bleeding causing a fall in hemoglobin level of 2 g/dL or more, or leading to transfuction of two or more units of whole blood or red cells. Bleeding that is not classified as major bleeding is minor.

    Measured: 5 years
