A positive correlation has been observed between the level of DNA damage and the severity of atherosclerotic lesions, as well as atherogenic risk factors such as smoking, hypertension and hyperlipidaemia. A number of in-vitro studies have implicated defective DNA repair in the development and progression of atherosclerotic lesions. In mouse models of atherosclerosis, the DNA repair signalling cascade has been shown to be amenable to pharmacological intervention and overexpression of specific repair proteins attenuate the development of atherosclerotic plaques. However, data regarding the role of DNA repair in the pathogenesis of atherosclerosis in humans are lacking. We have preliminary data indicating reduced DNA repair activity in patients with stable angina. This study will determine the molecular basis and the biological consequences of this observation.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients undergoing an assessment of thier coronary anatomy either by computerised tomography coronary angiogram or invasive coroanry angiogram at a large university teaching hospital performed as part of thier routine care.', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age ≥18 years\n* Ability to provide written informed consent\n\nExclusion Criteria:\n\n* Age ≥ 80 years\n* Inability to provide written informed consent\n* Presentation with an acute coronary syndrome\n* Severe valvular heart disease\n* Hypertrophic cardiomyopathy\n* Left ventricular ejection fraction ≤ 35%\n* Prior coronary revascularisation (surgical or percutaneous)\n* Diabetes Mellitus\n* Clinical evidence of peripheral vascular disease\n* Prior history of cerebrovascular disease\n* Malignancy\n* Active inflammatory disorders (e.g. rheumatoid arthritis/connective tissue disorder)\n* Renal impairment eGFR \\<60ml/min/1.73m2\n* Anaemia (Hb \\<100g/dL)'}, 'identificationModule': {'nctId': 'NCT04453267', 'acronym': 'DECODE II', 'briefTitle': 'DNA Repair in Patients With Stable Angina.', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital Southampton NHS Foundation Trust'}, 'officialTitle': 'DNA Repair in Patients With Stable Angina.', 'orgStudyIdInfo': {'id': 'CAR0566'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Patient Arm.', 'description': 'Consecutive patients undergoing elective percutaneous coronary intervention (PCI) or isolated coronary artery bypass grafting (CABG) for symptomatic stable angina (SA) despite optimal medical therapy at the University Hospital Southampton NHS Foundation Trust will be prospectively enrolled (n=86).\n\nNo interventions administered. 40ml of whole blood in EDTA vials to be taken for cellular separation and analysis.'}, {'label': 'Age and gender matched controls', 'description': 'Age and gender-matched patients being investigated for chest pain with unobstructed coronary arteries, defined as coronary stenosis ≤ 30% in any major epicardial vessel on CT or invasive coronary angiography, will also be recruited as controls (n=86).\n\n40ml of whole blood in EDTA vials to be taken for cellular separation and analysis.'}]}, 'contactsLocationsModule': {'locations': [{'zip': 'SO16 6YD', 'city': 'Southampton', 'state': 'Hampshire', 'status': 'RECRUITING', 'country': 'United Kingdom', 'contacts': [{'name': 'Michael Mahmoudi, MD,PhD', 'role': 'CONTACT', 'email': 'michael.mahmoudi@uhs.nhs.uk', 'phone': '0044 (0)23801208538', 'phoneExt': '8538'}], 'facility': 'University Hospital Southampton NHS Foundation Trust', 'geoPoint': {'lat': 50.90395, 'lon': -1.40428}}], 'centralContacts': [{'name': 'Thomas R Gilpin, MBBCh', 'role': 'CONTACT', 'email': 'thomas.gilpin@uhs.nhs.uk', 'phone': '0044 (0)2380777222', 'phoneExt': '3912'}, {'name': 'Zoe Nicholas, BSc', 'role': 'CONTACT', 'email': 'zoe.nicholas@uhs.nhs.uk', 'phone': '0044 (0)2380777222', 'phoneExt': '8538'}], 'overallOfficials': [{'name': 'Michael Mahmoudi, MD,PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University Hospital Southampton NHS Foundation Trust'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University Hospital Southampton NHS Foundation Trust', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
