Aim. To investigate the impact of hyperglycemia on the results of percutaneous coronary interventions (PCIs) in patients with acute ST-segment elevation myocardial infarction (ASTEMI). Subjects and methods. A study group consisted of 511 patients with hyperglycemia (blood glucose level (BGL) ≥7.77 mmol/L) who underwent primary PCIs in the period from 2005 to 2015. A comparison group included 579 patients (BGL ≥7.77 mmol/L). Results. Assessment of the results of hospital interventions revealed that the mortality rates in patients with hyperglycemia proved to be higher than in those with normal BGL (6.5 and 2.6%, respectively; p=0.002). No differences were found in the rates of stent thrombosis (1 and 1.4%; p=0.541) and recurrent myocardial infarction (1.2 and 1.6%; p=0.591). Major adverse cardiac events, including death, recurrent infarction, and stent thrombosis, were more frequently determined in the hyperglycemic patients (7.6 and 4.3%; p=0.020). No-reflow phenomenon statistically significantly more frequently developed in the patients with hyperglycemia (6.8 and 3.3%; p=0.007). Binary logistic regression analysis showed that the presence of hyperglycemia served as an independent predictor of hospital mortality (odds ratio (OR) 2.6; 95% confidence interval (CI), 1.4 to 4.8; p=0.002). The application of a random probability sampling technique revealed that mortality remained statistically significantly higher in the hyperglycemic patients than in the normoglycemic individuals at admission (6.7 and 2.6%; р=0.011). Conclusion. PCIs in patients with ASTEMI and hyperglycemia are characterized by higher mortality rates and the risk of major adverse cardiac events. Admission hyperglycemia is an independent predictor of hospital mortality.

Background Myocardial infarction can be a trigger of Takotsubo syndrome. We recently characterized imaging features of acute myocardial infarction-induced Takotsubo syndrome (“Takotsubo effect”). In this study, we investigate diagnostic and prognostic implications of Takotsubo effect in patients with anterior wall ST-segment elevation myocardial infarction. Methods We enrolled 111 consecutive patients who developed anterior wall ST-segment elevation myocardial infarction and received percutaneous coronary intervention, and studied systolic/diastolic function, hemodynamic consequences, adverse cardiac events, as well as 30-day and five-year outcomes in patients with and without Takotsubo effect. Results Patients with Takotsubo effect showed significantly worse average peak systolic longitudinal strain (–9.5 ± 2.6% vs –11.1 ± 3.6%, p = 0.038), left ventricular ejection fraction (38.5 ± 6.8% vs 47.7 ± 8.7%, p = 0.000) and myocardial performance index (0.54 ± 0.17 vs 0.37 ± 0.15, p = 0.000) within 48 h of myocardial infarction. There was no significant difference between the two groups in diastolic ventricular filling pressures, hemodynamic consequences, and 30-day rehospitalization and mortality (Gehan-Breslow-Wilcoxon test: p = 0.157). However, patients with Takotsubo effect developed more major adverse cardiac events (log-rank test: p = 0.019) when tested at the five-year follow-up. Cox regression analysis revealed that age, hypotension, tricuspid annular plane systolic excursion, and Takotsubo effect were independent prediction factors for five-year major adverse cardiac events. The Doppler/tissue Doppler parameter E/e’ correlated with MACE only in patients without Takotsubo effect. Conclusion Takotsubo effect secondary to anterior ST-segment elevation myocardial infarction predicts a worse long-term prognosis.

Abstract Background/Introduction Although optimal revascularization strategy in patients with ST-segment elevation myocardial infarction with multivessel coronary artery disease (MVD) was well established, there are few studies which investigated optimal revascularization strategy in non-ST-segment elevation myocardial infarction (NSTEM) with MVD. Purpose We investigated 2-year clinical outcomes according to strategy of revascularization in patients with NSTEMI and MVD. Methods Between November 2011 and October 2015, a total of 2474 patients with NSTEMI and MVD who underwent successful percutaneous coronary intervention were analyzed from the Korea Acute Myocardial Infarction Registry-National Institute of Health (staged 308, one-time 1043 and culprit-only 1123 patients). We did not include patients with left main disease and cardiogenic shock. Primary endpoint was major adverse cardiac events (MACE: the composite of cardiac death, myocardial infarction [MI] or target-vessel revascularization [TVR]) during 2-year follow-up (median 737 days [interquartile range 705–764]). We also analyzed the of all-cause mortality, stroke and non-TVR. Results Baseline characteristics such as age, gender, and prevalence of atherosclerotic risk factors between multivessel revascularization (MVR; staged or one-time revascularization) and CVR were similar. There was also no difference in symptom to balloon time in 2 groups. MACE occurred in 305 patients (12.3%) during 2-year follow-up. MVR could reduce incidence of MACE (10.2% vs. 14.9%; adjusted hazard ratio [HR] 1.50 for CVR, 95% confidence interval [CI] 1.20–1.88, p<0.001), all-cause death (8.4% vs. 12.1%; adjusted HR 1.45 for CVR, 95% CI 1.13–1.87, p=0.003) and non-TVR (1,9% vs. 7.0%; adjusted HR 3.99 for CVR, 95% CI 2.55–6.27, p<0.001). There was no difference in incidence of stroke between MVR and CVR. We also analyzed same analysis between staged and one-time revascularization. Complete revascularization was more achieved in one-time revascularization group compared to staged revascularization group (62.0% vs. 76.1%, p<0.001). In multivariate Cox-regression analysis, staged revascularization was not associated with improved clinical outcomes in terms of MACE (HR 0.74, 95% CI 0.50–1.09, p=0.126), all-cause death (HR 1.07, 95% CI 0.69–1.68, p=0.759), stroke (HR 1.75, 95% CI 0.68–4.52, p=0.245) and non-TVR (HR 2.56, 95% CI 0.75–8.68, p=0.132). Analysis by propensity score matching and inverse probability of treatment weighting did not significantly affect the results. Conclusions MVR reduced 2-year adverse cardiac events in patients with NSTEMI and MVD compared to CVR. However, staged revascularization was not superior to one-time revascularization for reducing MACE among NSTEMI patients with MVD who received MVR.

Background In addition to proinflammatory properties, eosinophils can stimulate platelet activation and enhance prothrombotic pathways. In this study, we aimed to investigate the association between the eosinophil percentage (EOS%) and major adverse cardiac events (MACE) in patients with ST-segment elevation myocardial infarction (STEMI). Methods This study enrolled a total of 1,909 patients who were diagnosed with STEMI. Ventricular arrhythmia, reinfarction, the need for cardiopulmonary resuscitation, target vessel revascularization, congestive heart failure, and cardiovascular mortality during index hospitalization were defined as MACE. Results Three hundred and eighty patients (19.7%) reached the combined endpoint with MACE. The rates of inhospital mortality and MACE were significantly higher in low EOS% group as compared to high EOS% group (4% vs. 1.1%, p < 0.01 and 32.8% vs. 11.3%, p < 0.01, respectively). On multivariate logistic regression analyses, EOS% (OR = 0.44, p < 0.01) was found to be one of the independent predictors of MACE. The EOS% lower than 0.60 on admission predicted inhospital MACE with a sensitivity of 68% and a specificity of 72% (AUC: 0.684, p < 0.01). Conclusions Low EOS% on admission may be associated with high inhospital MACE in STEMI patients. EOS% may be used as a novel biomarker for risk stratification of these patients.
