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.
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).

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.

| Change in baseline ASPI and ADP-induced platelet aggregation at 6 months | The primary outcome measure is platelet reactivity measured at 6-months. Response is calculated according to high platelet reactivity (HPR). Rates of HPR will be determined according to recently published definitions of HPR for multiple electrode aggregometry in patients undergoing percutaneous coronary intervention, >46 AU for ADP test and >40 for ASPI test. Response rate will be calculated on an intention to treat basis as the total number of patients responding as a proportion of all patients randomised and reported descriptively with 95% confidence intervals. Any patients who are not assessable at 6-months will be classed as a non-responder. | Baseline to 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Change in inflammatory markers (myeloperoxidase (MPO) measured by routine blood test at baseline, 1 month and 6 months | Measuring changes in inflammatory markers to investigate if treatment with APT is associated with reduced inflammatory marker levels (myeloperoxidase (MPO)). | Baseline to 6 months |
| Change in inflammatory markers (interleukin-6 (IL-6) measured by routine blood test at baseline, 1 month and 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Rates of major and minor bleeding as defined by the TIMI scale | Rates of bleeding will be classified as per the TIMI Scale: Major - Intracranial haemorrhage or a ≥5 g/dl decrease in the haemoglobin concentration or a ≥15% absolute decrease in the haematocrit Minor- Observed blood loss: ≥3 g/dl decrease in the haemoglobin concentration or ≥10% decrease in the haematocrit Minor- No observed blood loss: ≥4 g/dl decrease in the haemoglobin concentration or ≥12% decrease in the haematocrit Minimal- Any clinically overt sign of haemorrhage (including imaging) that is associated with a <3 g/dl decrease in the haemoglobin concentration or <9% decrease in the haematocrit All Adverse Events (AE) will be reported descriptively as the number of patients experiencing an AE as a proportion of the total number of patients starting treatment. |

| Quality of life using EuroQoL-5D-5L health-related quality of life instrument | The EQ-5D-5L consists of the EQ-5D-5L descriptive system and the EQ Visual Analogue scale (EQ VAS). The descriptive system has 5 dimensions (mobility, self care, usual activities, pain/discomfort, anxiety/depression), each with 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The respondent indicates his/her health state in each of the 5 dimensions. This decision results in a 1-digit number expressing the level selected for that dimension. The digits for 5 dimensions can be combined in a 5-digit number describing the respondent's health state. The EQ Visual Analogue Scale records the respondent's self-rated health on a vertical, visual analogue scale (0-100) where the endpoints are labelled 'Best imaginable health state' (100) and 'Worst imaginable health state' (0). This information will be used as a quantitative measure of health outcome as judged by the individual respondents. | Baseline and 6-months |
