Conditions
Summary
The aim of this research, proposed and funded by PlaqueTec and co-ordinated by Papworth Trials Unit Collaboration, is to demonstrate the performance of the coronary artery blood sampling device (Liquid Biospy System, LBS) and establish its usefulness to collect a range of disease biomolecules from the coronary artery of interest. Using the data generated from extensive analysis of the blood samples, key biomarker data will be generated that will close a knowledge gap and facilitate the development of tailored treatments for coronary artery disease.
Eligibility
Inclusion Criteria6
- ≥18 years of age, have capacity and be willing to provide informed consent to participate
- Clinical evidence of obstructive coronary artery disease and be scheduled for either:
- Elective coronary angiography +/- proceed for stable angina OR
- Elective PCI for stable angina with known bystander disease OR
- Angiography +/- proceed for Troponin negative unstable angina
- Suitable lesion identified meeting angiographic criteria for LBS deployment and Cardiologist comfortable to deploy OCT and LBS on study lesion before carrying out PCI on any lesion
Exclusion Criteria18
- Myocardial Infarction within 30 days of procedure.
- Chronic renal failure (eGFR\<30ml/min/1.73m2).
- Contrast allergy.
- Hypotension, shock or haemodynamic instability.
- Ventricular arrhythmia.
- Chronic Heart Failure (NYHA ≥ 3) or LVEF ≤ 30%.
- Immunocompromised or receiving immunosuppressant therapy.
- Any active disease that in the opinion of the investigator makes the subject unsuitable for the research procedure or subject life expectancy less than 1 year.
- Active infection or sepsis (significant CRP elevation and/or requiring antibiotics).
- Active systemic inflammatory condition.
- Inability to receive anticoagulants or antiplatelets or uncorrected bleeding disorder or deranged platelet count.
- Is pregnant.
- Deemed high clinical risk or unsuitable for the procedure for any reason by the treating clinician.
- Target lesion is in the left main coronary artery.
- Unsuitable coronary anatomy (vessel tortuosity \[\>45 degree bend\], moderate/ severe calcification angiographically, ostial disease).
- Presence of thrombus in the target vessel.
- Prior PCI or stent or graft in vessel identified for LBS sampling.
- No clinical indication for either a PCI or a pressure wire assessment on any lesion.
