Previous studies have shown a worse prognosis in unstable angina patients with elevated serum troponin T values. Consecutive patients (n = 117) with Braunwald class IIIB angina were included in the study. Serum samples for troponin T were obtained at admission and every 6 to 8 hours for 18 to 24 hours. Acute myocardial infarction was excluded by routine creatine kinase measurements. All patients underwent coronary angiography before discharge. Cardiac events including cardiac death and myocardial infarction were recorded. Two thirds of the patients with unstable angina had no increase in serum troponin T (<0.1 microg/L) (n = 80). They had a lower incidence of 3-vessel disease (26% vs 46%, p <0.001), left main disease (5% vs 16%, p = 0.04), visible thrombus (4% vs 22%, p = 0.006), and less severe stenosis of the culprit artery (65% vs 84%, p <0.004) than patients with elevated serum troponin T values (> or =0.1 microg/L) (n = 37). The 1-year cardiac event rate was 0% versus 19% in patients with troponin T values <0.1 microg/L compared with patients with serum troponin T values > or =0.1 microg/L (p <0.0001). It was concluded that patients with unstable angina and no release of troponin T have less severe coronary artery disease, and have an excellent prognosis. It is suggested that these patients may be managed more conservatively and without invasive evaluation before discharge.","is_dataset_classified":null,"base_score":4.07753744390572,"endowment":4.07753744390572,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"10758918","pmcid":null,"openalex_id":"https://openalex.org/W2115768769","authors":[],"funders":[],"total_grants":0,"fwci":4.7714,"citation_percentile":0.95277694,"influential_citations":0,"citation_trend":[{"year":2012,"count":1},{"year":2013,"count":1},{"year":2014,"count":1},{"year":2015,"count":1},{"year":2016,"count":1},{"year":2017,"count":1},{"year":2018,"count":1},{"year":2021,"count":2},{"year":2022,"count":1},{"year":2024,"count":1},{"year":2025,"count":1}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0002914999008723?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0002914999008723?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/s0002-9149(99)00872-3","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/10758918","host_type":"repository"}],"fields_of_study":["Acute Myocardial Infarction Research","Coronary Interventions and Diagnostics","Cardiac Imaging and Diagnostics","Adult","Aged","Aged, 80 and over","Angina, Unstable","Biomarkers","Coronary Angiography","Coronary Care Units","Death, Sudden, Cardiac","Electrocardiography","Female","Hospital Mortality","Humans","Incidence","Male","Middle Aged","Myocardial Infarction","New York","Prognosis","Retrospective Studies","Troponin T"],"mesh_terms":["Adult","Aged","Aged, 80 and over","Angina, Unstable","Coronary Care Units","Electrocardiography","Female","Humans","Male","Middle Aged","Myocardial Infarction","New York","Prognosis","Retrospective Studies","Biomarkers","Incidence","Death, Sudden, Cardiac","Coronary Angiography","Hospital Mortality","Troponin T"],"keywords":["Cardiology","Internal medicine","Unstable angina","Medicine","Troponin","Angina","Troponin T","Coronary angiography","Stable angina","Coronary heart disease","Myocardial infarction"],"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":"2026-08-18T14:07:41.658964Z","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":[]}
