METHODS: Troponin-T levels were assessed before and repeatedly for 64 hours after coronary bypass surgery in 100 patients with unstable and 100 with stable angina pectoris. RESULTS: Postoperative troponin-T levels rose significantly within 6 hours followed by a decline until 64 hours. In unstable patients who had pain within two days and an acute myocardial infarction within two weeks before the operation (Braunwald class IIIC), Troponin-T rose to high levels that persisted for 64 h. Sixty-seven percent of these patients had an elevated troponin-T >0.10 microg/l already before the operation and a perioperative myocardial infarction was recorded in 27%. In contrast, postoperative troponin-T levels in remaining patients classified as unstable were similar to those in patients with stable angina. Elective operations in the control group were performed with a low risk of adverse postoperative events. CONCLUSIONS: Patients with Braunwald class IIIC unstable angina suffered to a great extent myocardial cell damage following coronary bypass surgery.","is_dataset_classified":null,"base_score":1.0986122886681096,"endowment":1.0986122886681096,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"10903059","pmcid":null,"openalex_id":"https://openalex.org/W2079921546","authors":[],"funders":[],"total_grants":0,"fwci":0.0,"citation_percentile":0.14928212,"influential_citations":0,"citation_trend":[],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://www.thieme-connect.de/products/ejournals/pdf/10.1055/s-2000-9639.pdf","host_type":"publisher"},{"url":"https://doi.org/10.1055/s-2000-9639","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/10903059","host_type":"repository"}],"fields_of_study":["Cardiac, Anesthesia and Surgical Outcomes","Acute Myocardial Infarction Research","Cardiac Ischemia and Reperfusion"],"mesh_terms":["Adult","Aged","Aged, 80 and over","Angina Pectoris","Angina, Unstable","Coronary Artery Bypass","Female","Humans","Male","Middle Aged","Myocardium","Postoperative Period","Prospective Studies","Troponin T"],"keywords":["Medicine","Unstable angina","Myocardial infarction","Perioperative","Troponin","Cardiology","Troponin T","Internal medicine","Bypass surgery","Troponin I","Angina","Coronary artery bypass surgery","Surgery","Artery"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-29T14:24:39.691344Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
