Prognostic Value of Residual Coronary Artery Lesions on the SYNTAX Scale in Patients with Acute Myocardial Infarction without SТ Segment Elevation in the Mid-Term Period.

Abstract
Aim To study the effect of residual coronary injury after a percutaneous coronary intervention (PCI), as evaluated with the SYNTAX scale (residual SYNTAX score, RSS), on the mid-term prognosis for patients with non-ST elevation acute myocardial infarction (NSTEMI) and also to determine threshold RSS values for patients at high and low risk of adverse cardiac events.Material and methods A single-center, retrospective study was performed. From 421 patients with NSTEMI after PCI with stenting, 169 patients were selected who originally had multivessel coronary disease and who had undergone a repeated inpatient examination, including mid-term (11.7±3.0 mos.) coronary angiography. The endpoints were recurrent clinical manifestations of angina, repeat revascularization (RR), unstable angina (UA), recurrent acute myocardial infarction (AMI), cardiac death, and also a composite endpoint (major adverse cardiac events, MACE) that included UA, recurrent AMI, and cardiac death. After revealing a significant direct correlation between RSS and the probability of recurrent AMI, UA, MACE, or RR (p <0.05) using the ROC analysis, we have established threshold RSS values that divided patients into groups with high and low risk of the cardiac events listed above.Results For a significantly high risk of recurrent AMI (area under the curve, AUC 0.79±0.05; 95 % confidence interval, CI 0.68-0.89; р=0.048), the threshold RSS score was 8 (sensitivity 100 %, specificity 70.9 %). For UA and MACE, the RSS scores were both 3 (AUC 0.68±0.5; 95 % CI 0.58-0.79; p=0.005 and AUC 0.71±0.05; 95 % CI 0.61-0.8; p=0.001, respectively). The probability of UA during the observation period with RSS >3 was 4.07 times higher and that of MACE was 5.23 times higher than with RSS<3 (95 % CI 1.44-11.49; р=0.01 and 95 % CI 1.88-14.53; р=0.001, respectively).Conclusion The study demonstrated a significant, direct correlation between the RSS and the risk of adverse cardiac events in patients with NSTEMI during one year of observation. Specific threshold values were obtained, which may help in choosing both the extent of revascularization and the tactics for postoperative management of patients.

Predictors of survival in patients with acute coronary syndrome undergoing percutaneous coronary intervention of unprotected left main coronary artery stenosis. Catheter Cardiovasc Interv 2019; 96:E27-E33. [PMID: 31512392 DOI: 10.1002/ccd.28495] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Revised: 07/30/2019] [Accepted: 08/28/2019] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Aim of this study was to investigate predictors of survival in unstable patients with high SYNTAX-1-score. BACKGROUND In significant unprotected left main coronary artery (ULMCA) stenosis, treatment options include percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG). While CABG is recommended for stable patients with ULMCA stenosis and a SYNTAX-1-score > 32, PCI may be preferable in unstable or high operative risk patients. METHODS Retrospective single-center all-comers registry study. RESULTS A total of 142 patients underwent ULMCA-PCI (~72.9 years, 23.2% females, 54.2% survival in 2-year follow-up), 84 of whom had a SYNTAX-1 > 32 (37.4 ± 12.8). Patients in the high-SYNTAX-1-group (score > 32) were more often in an acute condition compared to low-SYNTAX-2-group (score ≤ 32) including acute myocardial infarction (76.2% vs. 57.4%, p = .024), cardiogenic shock (48.2% vs. 14.8%, p = .001), or need for mechanical support (36.1% vs. 11.1%, p = .001). Survival was predicted by the acute condition including cardiogenic shock (OR 0.06 and 0.05) and myocardial infarction (OR 0.03 and 0.34) in both groups. Performance of the SYNTAX-1-score was limited in our patient collective in both groups (c-index 0.65 vs. 0.63) while SYNTAX-2-PCI-score performed better (c-index 0.67 vs. 0.67). EuroScore II had the best discriminative ability (c-index 0.87 vs. 0.78). CONCLUSIONS The majority of patients undergoing ULMCA-PCI presented in acute conditions with high SYNTAX-1-score, and is therefore underrepresented in clinical trials. Prognosis was best predicted by the acute condition and the EuroScore II. These data suggest that therapy in unstable patients should be guided by clinical condition over the anatomical SYNTAX-1-score.
