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.

Acute coronary syndromes (ACS) without ST elevation (which include unstable angina [UA] and non ST elevation MI [NSTEMI]) are caused by dynamic changes in the atherosclerotic plaque and coronary blood flow. To determine characteristics, in-hospital outcome and management of patients with ACS without ST elevation. The total of 502 patients were enrolled. Inclusion criteria were: rest angina within the last 24 hours, ST-segment deviation (>0,05 mV), T-wave inversion (>0,1 mV) in at least two leads, positive serum cardiac markers. There were 63,3% of patients with Braunwald's IIIB UA and 6,8% with IIIC UA, 29,9% of patients were diagnosed with NSTEMI. All patients were diagnosed invasively with subsequent revascularization (PCI-73,1% or CABG-16,7%) if apprioppriate. 1,6% of patients underwent PCI and elective CABG and 16,7% of patients were treated conservatively. Overall mortality was 2,98%--PCI subgroup (N = 367) 1,36%, CABG subgroup (N = 84) 8,33% and conservative subgroup (N = 43) 6,07%. Non-fatal myocardial infarction (MI) complicated the hospital course in 0,99%, 0,27%, 3,57%, and 2,32% of patients respectively. 1,4%, 0,54%, 6% and 0% of patients respectively had fatal MI. Early invasive strategy in patients with ACS without ST elevation is efficacious method of treatment.
