Angina, StableNCT05319366
Atherosclerotic Lesion Proteomics by Harvesting Angioplasty Balloons (ALPHA).
An observational study of Angina, Stable and Angina, Unstable, run by Copenhagen University Hospital, Rigshospitalet at 2 sites in Denmark.
Trial summary
The purpose of the study is to identify proteins, metabolites and signal pathways related directly to symptomatic atherosclerosis and to disease progression. In the study, we use residual material from angioplasty catheter balloons and from vascular surgery plus blood samples. Read more about this study

About this study
Official title: Proteomics- og Metabolomics-undersøgelse af Materiale Ekstraheret Fra Ballonkatetre Anvendt Til Ballon-udvidelsesbehandling Hos Patienter Med Symptomatisk åreforkalkningssygdom
The purpose of the study is to identify proteins, metabolites and signal pathways related directly to symptomatic atherosclerosis and to disease progression. In the study, we use residual material from angioplasty catheter balloons and from vascular surgery plus blood samples. It is the hypothesis that material left on the catheter balloons used for angioplasty can be used for proteomics and metabolomics evaluation that will identify inflammation-associated proteins and signaling pathways directly in the diseased vessel. The tissue samples will be collected after the procedure and blood samples will be collected at the procedure plus after 6-12 months. The tissue and blood samples will be analyzed using mass spectrometry methods and a standard panel of biomarkers will also be analyzed using standardized methods. The analyses will include study of inflammation-associated peptides observed in autoinflammation as well as thrombogenic signaling pathways and local expression of biomarkers. The analyses of proteins, metabolites and/or biomarkers will be compared between cases (stable angina, unstable angina/non-STEMI, STEMI and vascular surgery) and controls (procedures not related to coronary artery diseases) to identify molecular processes related directly to symptomatic atherosclerosis and will be associated with disease progression using data from medical journals and National Health registries. The study will recruit 225 patients from Rigshospitalet University Hospital, Copenhagen, and Herlev-Gentofte Hospital.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Stable angina | 50 patients with stable angina will be included and tissue samples from balloon cathether and blood samples will be collected | |
| Unstable angina/non-ST-segment elevation myocardial infarction | 50 patients with unstable angina/non-ST-segment elevation myocardial infarction will be included and tissue samples from balloon cathether and blood samples will be collected | |
| ST-segment elevation myocardial infarction | 50 patients with ST-segment elevation myocardial infarction will be included and tissue samples from balloon cathether and blood samples will be collected | |
| Controls | 50 patients without corornary arthery-related treatment will be included and tissue samples from balloon cathether and blood samples will be collected | |
| Vascular surgery | 25 patients who undergo will be included and tissue samples and blood samples will be collected |
