About

Patients with COPD (chronic bronchitis and/or emphysema) are known to be at an increased risk of heart disease and death due to heart attacks. There are several possible reasons for this, one of which is an increased tendency of the blood to clot, that can give rise to blood clot formation in the coronary arteries, and lead to heart attack. Medications such as Aspirin and another new blood thinning tablet called Ticagrelor are already used for patients with heart attacks. Given that patients with COPD are at higher risk of heart attack, the investigators wish to see if these tablets that can prevent blood clot formation in heart arteries might also prevent heart attacks happening in COPD patients. The investigators hope to understand the effects by measuring clotting and inflammation in the blood. All patients will be followed up for 6-months.

In addition the investigators wish to study COPD patients who do not have a high risk of developing future heart problems using the QRISK score to study their well being over a 1 year period to see if they might also benefit from blood thinning medications.

Full description

The APPLE-COPD: ICON2 trial is a double blinded, proof-of-concept, randomised controlled trial that will include patients who have not been previously targeted in clinical cardiovascular research. The study will consist of patients with a lung condition called chronic obstructive pulmonary disease (COPD) who have not previously been diagnosed with coronary artery disease (CAD) and yet are at higher risk of CAD, myocardial infarction, and excess mortality (as determined by QRISK2 score). The QRISK2 is a simple questionnaire for heart disease that uses well known risk factors such as age, high blood pressure, smoking status and abnormal cholesterol levels. A QRISK score over 20 (20% risk of a cardiovascular event over the next ten years) is already used as a prompt to consider cholesterol lowering therapy (such as statins).

Patients with COPD (chronic bronchitis and/or emphysema) are known to be at an increased risk of heart disease and death due to heart attacks. There are several possible reasons for this, one of which is an increased tendency of the blood to clot which can give rise to blood clot formation in the coronary arteries, and lead to heart attack. Medications such as Aspirin and another new blood thinning tablet called Ticagrelor are already used for patients with heart attacks. Given that patients with COPD are at higher risk of heart attack, the investigators wish to see if these tablets that can prevent blood clot formation in heart arteries, might also prevent heart attacks happening in COPD patients. The investigators hope to understand the effects by measuring clotting and inflammation in the blood.

Aspirin and Ticagrelor are widely used in the UK for the management of coronary artery disease. For purposes of this study, Aspirin and Ticagrelor will be treated as an Investigational Medicinal Product (IMP). As a 2x2 factorial design, the primary analyses are based on a comparison of i) Aspirin vs no Aspirin and ii) Ticagrelor vs. no Ticagrelor (resulting in 4 treatment arms). Treatment allocation will be blinded to both the investigator and the participant.

Participants allocated to the treatment arms will be requested to take their trial medication for 6 months and will then be followed up clinically for a further 6 months by the research team to monitor any adverse events and the participant's well-being.

Participants allocated to the observational arm will be followed up for 1 year.

At 1 year all trial procedures will end and the patient will continue to receive routine care by the clinical care team.
