Long-term results of 11,021 patients with chronic coronary syndrome and after coronarography (from the PRESAGE Registry)

INTRODUCTION: There is a paucity of real‑world registries concerning patients with chronic coronary syndromes (CCS). OBJECTIVES: We aimed to assess the long‑term outcomes of patients with CCS and after coronary angiography performed in accordance with the treatment strategy. PATIENTS AND METHODS: The analysis involved 11 021 patients treated in a single center between 2006 and 2016 who were enrolled into the ongoing PRESAGE registry. Based on the results of coronary angiography and the treatment strategy adopted, patients were classified into 4 groups: with nonsignificant lesions (n = 3637), undergoing percutaneous coronary intervention (n = 4678), undergoing coronary artery bypass grafting (CABG; n = 997), and receiving conservative treatment (notwithstanding significant lesions on an angiogram; n = 1709). All‑cause death, assessed in every study group at 1-, 3-, and 5‑year follow‑up, was regarded as the primary outcome measure. RESULTS: The mean (SD) age of the study patients was 64.6 (9.5) years, and women constituted 35% of the cohort. Patients treated conservatively were the oldest (mean [SD] age, 64.9 [9.3] years) in the group and showed the highest prevalence of previous myocardial infarction (50.5%), CABG (31.8%), diabetes (40.3%), chronic total occlusion (65.5%), and left ventricular ejection fraction below 35% (24.4%). Death from any cause in patients with nonsignificant lesions, undergoing percutaneous coronary intervention, undergoing CABG, and receiving conservative treatment occurred 5 years following the index hospitalization in 11.2%, 16.2%, 9.7%, and 21% of those patients, respectively. CONCLUSIONS: The PRESAGE registry provides valuable information about the clinical characteristics and long‑term outcomes of patients with CCS. The population of CCS patients is heterogeneous, and long‑term prognosis is also varied. The poorest characteristics and outcomes were reported in patients with significant lesions and ineligible for revascularization procedures.
