Background: ST Elevation Myocardial Infarction (STEMI) may cause Major Cardiovascular Event (MACE). Revascularization needs to be done in all STEMI patients to restore coronary blood flow, hence saving myocardial perfusion. ST Segment Depression (STSD) in reciprocal ECG lead is associated with poor prognosis in STEMI patients receiving fibrinolytic therapy. The main purpose of this study is to evaluate MACE in STEMI patients receiving fibrinolytic therapy using resolution in STSD. Methods: This cohort prospective study with 60 subjects of STEMI patients which are evaluated for MACE (death, heart failure, and rehospitalization) within 30 days after myocardial infarction. Resolution in STSD is defined as resolution ≥ 50% STSD in reciprocal leads within 90 minutes after fibrinolytic therapy.Results: Bivariate analysis showed that Ejection fraction (EF) <40% with OR 8,32 (2,11-32,74), p=0,001; smoking with OR 4,17 (1,05-16,57), p=0,034; Anterior STEMI with OR 3,94 (1,11-13,90), p= 0,027; Creatinine > 1,97 mg/dl with OR 3,69 (1,18-11,55), p= 0,022; complete outpatient medication with OR 5,23 (1,61-17,01), p= 0,004; fragmented QRS with OR 5,23 (1,61-17,01), p= 0,001; resolution in STSD with OR 26,35 (5,16-134, 40), p=<0,001; resolution in ST Segment Elevation with OR 10,5 (2,97-37,24), p=<0,001; are proven to be determining factor for MACE within 30 days. Multivariate analysis showed that among those determining factors for MACE, resolution in STSD on reciprocal leads is evidently the most dominant factor for predicting MACE within 30 days in STEMI patients receiving fibrinolytic therapy [OR 11.47 (1.14-115.10), p=0.038].Conclusion: There is significant difference in MACE within 30 days after myocardial infarction (MI) between patients with and without resolution in STSD. The subjects without resolution in STSD showed higher MACE incidence. Resolution in STSD is evidently an independent predictor for MACE within 30 days after myocardial infarction in STEMI patients.Keywords: Resolution in STSD, MACE, STEMI, Fibrinolytic

Abstract Aims To assess the impact of the lockdown due to coronavirus disease 2019 (COVID-19) on key quality indicators for the treatment of ST-segment elevation myocardial infarction (STEMI) patients. Methods Data were obtained from 41 hospitals participating in the prospective Feedback Intervention and Treatment Times in ST-Elevation Myocardial Infarction (FITT-STEMI) study, including 15,800 patients treated for acute STEMI from January 2017 to the end of March 2020. Results There was a 12.6% decrease in the total number of STEMI patients treated at the peak of the pandemic in March 2020 as compared to the mean number treated in the March months of the preceding years. This was accompanied by a significant difference among the modes of admission to hospitals (p = 0.017) with a particular decline in intra-hospital infarctions and transfer patients from other hospitals, while the proportion of patients transported by emergency medical service (EMS) remained stable. In EMS-transported patients, predefined quality indicators, such as percentages of pre-hospital ECGs (both 97%, 95% CI = − 2.2–2.7, p = 0.846), direct transports from the scene to the catheterization laboratory bypassing the emergency department (68% vs. 66%, 95% CI = − 4.9–7.9, p = 0.641), and contact-to-balloon-times of less than or equal to 90 min (58.3% vs. 57.8%, 95%CI = − 6.2–7.2, p = 0.879) were not significantly altered during the COVID-19 crisis, as was in-hospital mortality (9.2% vs. 8.5%, 95% CI = − 3.2–4.5, p = 0.739). Conclusions Clinically important indicators for STEMI management were unaffected at the peak of COVID-19, suggesting that the pre-existing logistic structure in the regional STEMI networks preserved high-quality standards even when challenged by a threatening pandemic.

Background: The coexistence of coronary heart disease and consequently, acute myocardial infarction with persistent ST-segment elevation (STEMI) and glucose metabolism disorders is well known. Still, glucose metabolism disorders in the STEMI population are not fully understood. We know that diabetes mellitus (DM) is a factor disabling the function of microcirculation, which in turn may affect the outcome of coronary intervention. The aim of this study was to evaluate the dynamics of ST-segment changes in ECG (electrocardiogram) in STEMI (ST-segment elevation myocardial infarction) patients with co-existing hyperglycaemia compared to those with normoglycaemia treated with a percutaneous coronary intervention (PCI), as well as to determine this parameter in the assessment of reperfusion effectiveness. Methods: The study included 92 patients with the diagnosis of STEMI enrolled in the PCI treatment and was divided into groups based on the glucose levels on admission (reactive hyperglycaemia): a group with higher glucose levels on admission (Glc ≥ 7.8 mmol/L, n = 46), a group with lower glucose levels on admission (Glc < 7.8 mmol/L, n = 46) and into groups based on the concentration of HbA1c: a group with a lower HbA1c level (<6.5% (48 mmol/mol), n=71) and a group with a higher level (≥6.5%, n=21). Results: On admission, there were no significant differences in terms of clinical characteristics between the groups of patients with normoglycemia and reactive hyperglycaemia. After PCI, the patients with normoglycemia had significantly higher (p = 0.021) dynamics of changes in the resolution of ST-segment elevation in ECG expressed in an indicator of sum STR (resolution of ST-elevation). A degree of resolution of ST elevation in ECG was significantly (p = 0.021) dependent on the level of blood glucose – higher the blood glucose level, weaker the resolution. The patients with glucose levels ≥7.8 mmol/L had significantly higher levels of CK and CK-MB during the first 48 hours of hospitalization. There was a statistically significant difference in the mean length of hospitalization between individuals from the group with lower and higher blood glucose levels on admission (p = 0.028). A 4-month follow-up revealed no significant difference in the incidence of major adverse cardiovascular events (MACE) in the study groups (p = 0.063). A 4-year follow-up of patients with higher levels of blood glucose on admission showed a higher incidence of MACE (p = 0.01). The patients with HbA1c ≥ 6.5% were older (p = 0.004), had a greater BMI > 30kg/m2 (p=0.019) and the lower ejection fraction of the left ventricle (p = 0.003) compared to those with the HbA1c levels <6.5%. The incidence of MACE in 4-month and 4-year follow-up was comparable in the study population.

Early resolution of ST-segment elevation (STR) is a potent predictor of better clinical outcome after PCI in ST elevation acute myocardial infarction (STEMI). The aim of this study was to determine the association of aspirated materials and serial change of ST elevation. We studied 150 consecutive STEMI patients with assessable ECG recording, in whom standard PCI was performed with the adjunctive use of aspiration thrombectomy. STR(+) was defined as more than 50% resolution of ST-segment elevation at 60min after PCI. Aspirated materials were pathologically classified into thrombus only group (fresh, lytic, or organized) or thrombus and atheroma complex group, and compared between STR(+) and STR(−). TIMI flow grade, IVUS findings after aspiration(ruptured plaque, calcification, thrombus and echo signal attenuation), area under the curve (AUC) of CK-MB release, and pathological findings were also compared between the two groups. Seventy-six patients (50.6%) showed STR and 74 patients didn’t. RCA culprit lesion was significantly more frequent in STR(+)(P<0.05). There was no significant difference in other patient characteristics or IVUS findings in the present cohort. AUC of CK-MB was lower in STR(+)(p=0.02). TIMI 3 flow was more frequently achieved in STR(+)(p<0.05). Fresh thrombus was more frequent in STR(+)(p<0.05), whereas atheromatous component and lytic or organized thrombus were frequently observed in STR(−)(p<0.05). Culprit lesions in STEMI, when atheroma and thrombus complex with lytic or organized thrombus was aspirated, caused more myocardial damage and less frequent STR.

AbstractST-segment elevation myocardial infarction (STEMI) is a life-threatening condition that requires emergent, complex, well-coordinated treatment. Although the primary goal of treatment is simple to describe—reperfusion as quickly as possible—the management process is complicated and is affected by multiple factors including location, patient, and practitioner characteristics. Hence, this narrative review will discuss the recommended management and treatment strategies of STEMI in the circumstances.

AbstractMajor adverse cardio-cerebrovascular events (MACCE) in ST-segment elevation myocardial infarction (STEMI) are still high, although there have been advances in pharmacology and interventional procedures. Proprotein convertase subtilisin/Kexin type 9 (PCSK9) is a serine protease regulating lipid metabolism associated with inflammation in acute coronary syndrome. The MACCE is possibly related to polymorphisms in PCSK9. A prospective cohort observational study was designed to confirm the association between polymorphism of E670G and R46L in the PCSK9 gene with MACCE in STEMI. The Cox proportional hazards model and Spearman correlation were utilized in the study. The Genotyping of PCSK9 and ELISA was assayed.Sixty-five of 423 STEMI patients experienced MACCE in 6 months. The E670G polymorphism in PCSK9 was associated with MACCE (hazard ratio = 45.40; 95% confidence interval: 5.30–390.30; p = 0.00). There was a significant difference of PCSK9 plasma levels in patients with previous statin consumption (310 [220–1,220] pg/mL) versus those free of any statins (280 [190–1,520] pg/mL) (p = 0.001).E670G polymorphism of PCSK9 was associated with MACCE in STEMI within a 6-month follow-up. The plasma PCSK9 level was higher in statin users.

Abstract Background Left ventricular negative remodelling after ST-segment elevation myocardial infarction (STEMI) is considered as the major cause for the poor prognosis. But the predisposing factors and potential mechanisms of left ventricular negative remodelling after STEMI remain not fully understood. The present research mainly assessed the association between the stress hyperglycaemia ratio (SHR) and left ventricular negative remodelling. Methods We recruited 127 first-time, anterior, and acute STEMI patients in the present study. All enrolled patients were divided into 2 subgroups equally according to the median value of SHR level (1.191). Echocardiography was conducted within 24 h after admission and 6 months post-STEMI to measure left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), and left ventricular end-systolic diameter (LVESD). Changes in echocardiography parameters (δLVEF, δLVEDD, δLVESD) were calculated as LVEF, LVEDD, and LVESD at 6 months after infarction minus baseline LVEF, LVEDD and LVESD, respectively. Results In the present study, the mean SHR was 1.22 ± 0.25 and there was significant difference in SHR between the 2 subgroups (1.05 (0.95, 1.11) vs 1.39 (1.28, 1.50), p < 0.0001). The global LVEF at 6 months post-STEMI was significantly higher in the low SHR group than the high SHR group (59.37 ± 7.33 vs 54.03 ± 9.64, p  = 0.001). Additionally, the global LVEDD (49.84 ± 5.10 vs 51.81 ± 5.60, p  = 0.040) and LVESD (33.27 ± 5.03 vs 35.38 ± 6.05, p  = 0.035) at 6 months after STEMI were lower in the low SHR group. Most importantly, after adjusting through multivariable linear regression analysis, SHR remained associated with δLVEF (beta = −9.825, 95% CI −15.168 to −4.481, p  < 0.0001), δLVEDD (beta = 4.879, 95% CI 1.725 to 8.069, p  = 0.003), and δLVESD (beta = 5.079, 95% CI 1.421 to 8.738, p  = 0.007). Conclusions In the present research, we demonstrated for the first time that SHR is significantly correlated with left ventricular negative remodelling after STEMI.

Background: There is little recent data describing the characteristics and outcomes of STEMI patients who do not undergo urgent reperfusion. Methods: Using the ACTION Registry®-GWTG™ database, we examined 232,208 STEMI patients presenting January 2007 through December 2013 at 793 U.S. centers. The cohort was divided into those who underwent reperfusion (n=194,916; 84%), had documented contraindication to reperfusion (n=31,518; 13.5%) and were eligible but not reperfused (n=5,774; 2.5%). Clinical characteristics and in-hospital outcomes were compared between these groups. Results: Compared with those reperfused, patients not reperfused were older, more often female and had higher rates of hypertension, diabetes, MI, stroke and atrial fibrillation. LBBB and CHF were more common in the non-reperfused groups upon presentation. The major documented contraindications to reperfusion were unsuitable anatomy for primary PCI (31%), symptoms onset > 12 hours (9%), patient/family refusal/DNR status (6%), resolved chest pain (6%) and ST elevation (5%) presentation to non-PCI centers (4%). Three-vessel disease and in-hospital CABG were more common in non-reperfused patients with and without contraindication compared with those receiving reperfusion (39 & 37% vs. 26%, p<0.001) and (17 & 17% vs. 3%, p<0.001 respectively). In-hospital outcomes are summarized in the table. Conclusion: Most STEMI patients who were not reperfused had a documented contraindication. Unsuitable anatomy for PCI was the major contributor to ineligibility. In hospital mortality, death/MI and cardiogenic shock were higher in the non-reperfused groups.

Abstract Background Brugada Syndrome is an inherited arrhythmogenic disease, characterized by the typical coved type ST-segment elevation in the right precordial leads from V1 through V3. The BrugadaDrugs.org Advisory Board recommends avoiding administration of propofol in patients with Brugada Syndrome. Since prospective studies are lacking, it was the purpose of this study to assess the electrocardiographic effects of propofol and etomidate on the ST- and QRS-segments. In this trial, it was hypothesized that administration of propofol or etomidate in bolus for induction of anesthesia, in patients with Brugada Syndrome, do not clinically affect the ST- and QRS-segments and do not induce arrhythmias. Methods In this prospective, double-blinded trial, 98 patients with established Brugada syndrome were randomized to receive propofol (2 to 3 mg/kg-1) or etomidate (0.2 to 0.3 mg/kg-1) for induction of anesthesia. The primary endpoints were the changes of the ST- and QRS-segment, and the occurrence of new arrhythmias upon induction of anesthesia. Results The analysis included 80 patients: 43 were administered propofol and 37 etomidate. None of the patients had a ST elevation greater than or equal to 0.2 mV, one in each group had a ST elevation of 0.15 mV. An ST depression up to −0.15mV was observed eleven times with propofol and five with etomidate. A QRS-prolongation of 25% upon induction was seen in one patient with propofol and three with etomidate. This trial failed to establish any evidence to suggest that changes in either group differed, with most percentiles being zero (median [25th, 75th], 0 [0, 0] vs. 0 [0, 0]). Finally, no new arrhythmias occurred perioperatively in both groups. Conclusions In this trial, there does not appear to be a significant difference in electrocardiographic changes in patients with Brugada syndrome when propofol versus etomidate were administered for induction of anesthesia. This study did not investigate electrocardiographic changes related to propofol used as an infusion for maintenance of anesthesia, so future studies would be warranted before conclusions about safety of propofol infusions in patients with Brugada syndrome can be determined.
