Background/Aim. Most patients with acute myocardial infarction with ST-segment elevation (STEMI) are still treated with pharmacological reperfusion, which is not always successful. That is the reason for searching possibilities for a better success of reperfusion with adding new antiplatelet drugs. The aim of this study was to investigate weather addition of clopidogrel as a second antiplatelet drug, improves the patency of the infarct-related artery after STEMI. Methods. We prospectively enrolled 65 patients, 29?72 years old, hospitalized due to the first STEMI within 6 hours after the onset of a chest pain. They were treated with a fibrinolytic agent (streptokinase or tissue plasminogen activator ? tPA), aspirin, and low molecular heparin (enoxaparin). A group of 50 patients, beside this therapy, received clopidogrel. Coronary angiography was performed between 5th and 10th day of hospitalization to assess for late patency of the infarct-related artery. Infarct-related artery was considered as patent if thrombolysis in myocardial infarction (TIMI) flow grade was 2 or 3, and as occluded if TIMI flow grade was 0 or 1. Results. In the group of patients who received double antiplatelet therapy (aspirin and clopidogrel), infarct-related artery was occluded in 3 cases (6%); in the group of patients without clopidogrel, infarct-related artery was occluded in 4 patients (26.7%), p < 0.05. There were less frequency of postinfarction angina (6% vs 13.3%), and rarer necessity for rescue percutaneous coronary intervention (4% vs. 13.3%) in the first group, but without statistical significance. Conclusion. Adding of clopidogrel to the standard reperfusion pharmacotherapy, as a second antiplatelet drug, increases the number of patients with patent infarct-related artery and the success of reperfusion.

Abstract Background Stress-induced hyperglycaemia at time of hospital admission has been linked to worse prognosis following acute myocardial infarction (AMI). The stress-hyperglycaemia ratio (SHR) index normalises the acute increase in blood glucose values to background glycaemic status. However, the optimal cut-off blood glucose and SHR values for predicting adverse outcomes post-AMI are unknown. As such, we determined the optimal blood glucose and SHR cut-offs for predicting 1-year all cause mortality in diabetic and non-diabetic non-ST-segment elevation myocardial infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI) patients. Methods We undertook a national, registry-based study of patients with AMI from January 2008 to December 2015. We determined the optimal blood glucose and SHR cut-off values using the Youden’s formula for 1-year all-cause mortality. We subsequently analyzed the sensitivity, specificity, positive and negative predictive values of the cut-offs in the diabetic and non-diabetic subgroups, stratified by the type of AMI. Results There were 5,841 STEMI and 4,105 NSTEMI in the study. In STEMI patients, both glucose and SHR were independent predictors of 1-year all-cause mortality [Glucose: OR 2.19 (95% CI 1.74–2.75); SHR: 2.19 (95% CI 1.73–2.78)]. However, in NSTEMI patients, glucose and SHR were not independently associated with 1-year all-cause mortality [Glucose: OR 1.37 (95% CI 1.00-1.89); SHR: 1.27 (95% CI 0.91–1.78)]. In STEMI patients, ROC analysis showed that SHR performed better than glucose (AUC for glucose 0.633 versus AUC for SHR 0.692, P < 0.001) in diabetic patients, whereas in non-diabetic patients, SHR and glucose performed equally well (AUC for glucose 0.720 versus AUC for SHR 0.717, P < 0.664). The optimal glucose cut-off values were 15.0mmol/L for diabetic STEMI patients and 11mmol/L for non-diabetic STEMI patients and the corresponding optimal cut-off values for SHR were 1.7 and 1.5, respectively. Conclusions Glucose on admission and SHR were independent predictors of 1-year all-cause mortality in STEMI, whereas this was not the case in NSTEMI patients. In STEMI setting, SHR performed better than admission glucose to predict 1-year all-cause mortality in diabetic patients, whereas in non-diabetic patients both SHR and glucose performed equally well.

Venous Stents

Venous thromboembolism is associated with significant morbidity and mortality if left untreated. Anticoagulation is the cornerstone of treatment. Venous stents are a relatively newer entity that are increasingly being used to treat venous stenosis/occlusion. It is a safe procedure, but complications include vein rupture, arterial puncture, retroperitoneal bleeding, and in-stent thrombosis. Stent migration is a rare but potentially fatal complication. We present a case of venous stent embolization to the heart that presented as a non-ST segment elevation myocardial infarction.

Abstract Background Cardiac troponin (cTn) is the preferred biomarker for the diagnosis of acute myocardial infarction (AMI). Octogenarians who presented cTn positive AMI are not usually recruited in clinical trials. Therefore, their clinical characteristics and prognosis are rarely investigated. Objective To study the characteristics and prognosis in octogenarians who presented cTn positive AMI. Methods and results The Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET) is a prospective and multicenter registry. A total of 3,283 consecutive AMI patients who were diagnosed by cTn-based criteria were included. The patients were divided into non-octogenarians (n=2,593) and octogenarians (n=690). Compared with non- octogenarians, octogenarians showed significantly lower incidence of diabetes mellitus (37.6% and 31.9%, p=0.006) and dyslipidemia (53.6% and 45.6%, p<0.001), and significantly higher incidence of hypertension (64.1% and 75.3%, p<0.001) and chronic kidney disease (38.7% and 68.7%, p<0.001). Octogenarians showed significantly longer onset to door time (p<0.001) and longer door to device time (p<0.001). Though, compared with non-octogenarians, octogenarians showed lower peak CK (2,506 and 1,926, p<0.001), LVEF was significantly lower in octogenarians (54.6% and 52.6%, p=0.005). The presentation of AMI was different between the two group. The incidence of ST-segment elevation MI (STEMI) was 70.7% in non-octogenarians and 62.0% in octogenarians. Non-STEMI with CK elevation and without CK elevation were 16.2% and 13.1% in non- octogenarians, and 20.9% and 17.1% in octogenarians. In-hospital mortality was higher in octogenarians (4.7% and 13.2%, P<0.001). Especially, octogenarians with STEMI and non-STEMI with CK elevation showed the highest in-hospital mortality. And octogenarians without CK elevation showed similar in hospital mortality with non-octogenarians with STEMI (Figure). Conclusions J-MINUET showed the poor prognosis of octogenarians who were diagnosed as AMI based on cTn. Acknowledgement/Funding None
