Background: The discharge of uncomplicated patients with ST-segment-elevation myocardial infarction (STEMI) within 48 to 72 hours has been proven safe and feasible. The safety and feasibility of the very early discharge (≤48 h) of such patients, especially during the COVID-19 pandemic with limited bed availability and infection risk, have yet to be evaluated. Methods:  In this cohort study on 108 patients with STEMI who presented to Farshchian Heart Center between February and May 2020, 30 patients received fibrinolysis and 78 were scheduled for emergent coronary angiography. One patient had no coronary obstruction, 3 underwent emergent surgery, and 3 had high-risk features mandating a prolonged stay. The remaining patients were assigned to either Group A (≤48 h) or Group B (>48 h) regarding hospital discharge. Demographic, angiographic, procedural, and outcome data were compared between the 2 groups. Results: Group A consisted of 51 patients, including 7 women (13.7%), at a mean age of 62.74±12.35 years, and Group B comprised 20 patients, including 4 women (20.0%), at a mean age of 65.20±12.82 years. The mean hospital length of stay was 38.02±9.15 hours in Group A and 88.20±23.31 hours in Group B (P<0.001). The mean stent diameter was smaller in Group B (3.19±0.34 mm vs 2.96±0.29 mm; P=0.008). Demographic, angiographic, procedural, and outcome data, including the rates of in-hospital, 1-week, and 1-month mortality, were similar between the 2 groups. Conclusion: This study shows that a hospital discharge in less than 48 hours in low-risk patients with STEMI is safe and feasible. The potential advantages of this approach in the COVID-19 pandemic should be balanced against its risks.

Acute Inferior Myocardial Infarction

Background: Inferior wall ST segment elevation myocardial infarction is considered to be at lower risk than anterior wall STEMI except in some cases. The aim of our study was to evaluate the relationships between on admission ST segment changes in lead aVR and short term in-hospital outcomes in acute isolated inferior myocardial infarction undergoing thrombolysis. Methods: Total 107 of first attack of inferior STEMI patients were included and all were thrombolysed by streptokinase. The sample population were divided into three groups based on the condition of ST segment in lead aVR on admission and in hospital outcomes were observed: Group –A: ST segment elevation ≥0.5 mm; Group –B: ST segment depression ≥0.5 mm; Group-C: Iso-electric ST segment. Results: 6.54% of study population had ST segment elevation in lead aVR, 53.27% had ST segment depression in lead aVR and 41.12% had isoelectric ST segment in lead aVR. During hospital stay mortality rates of patients of Group A, Group B and Group C were 33.3%, 5.3% and 4.5 % respectively; rates of cardiogenic shock were 33.3%, 8.8% and 2.3% respectively; heart failure rates were 50.0%, 15.8% and 4.5% respectively; rates of recurrent angina after thrombolysis were 66.7%, 33.3% and 6.8% respectively in three groups and the mean LVEF were 40.17, 48.61 and 52.50 respectively. Conclusion: The on admission-isoelectric ST segment in lead aVR in acute inferior myocardial infarction predicted better in-hospital outcomes in comparison to ST segment elevation and ST segment depression in aVR. On the other hand, ST segment elevation in lead aVR predicted worse in-hospital outcomes than ST segment depression in acute inferior myocardial infarction in spite of reperfusion by thrombolytic.

Abstract Objective Reperfusion of ischemic myocardium generates oxidative stress, which itself can mediate myocardial injury. So, in this study, we investigated the level of oxidative stress markers and its association with clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention. Results As indicated in the results, Post MI (Myocardial Infarction) heart failure was significantly higher in the group A (11% vs 4%, p = 0.047). Complete STR (ST-segment resolution) was observed to be significantly higher in the group B (36% vs 17%, p = 0.006). The SOD (Superoxide dismutase) and GPX (Glutathione peroxidase) levels were significantly higher in the group B compared to the other group (1547.51 ± 328.29 vs. 1449.97 ± 246.06, p = 0.019 and 60.62 ± 11.95 vs 57.41 ± 10.14, p = 0.042). The levels of GPX and SOD were shown to be directly related with complete STR and post PCI (Percutaneous coronary intervention)TIMI(Thrombolysis in Myocardial Infarction) flow 3 in the group A (p = 0.002 and p < 0.01, p = 0.005 and p < 0.02, respectively).

Objective.The aim of the present study was to investigate the predictive value of neutrophil count for no-reflow in patients with ST-segment elevation myocardial infarction (STEMI) who underwent successful primary percutaneous intervention (PCI).Methods.We conducted a retrospective study of 361 patients diagnosed with acute STEMI between 2011 and 2015. All patients underwent successful PCI within 12 h from the onset of symptoms. Angiographic no-reflow was diagnosed based on a post-PCI thrombolysis in myocardial infarction flow grade ≤ 2 without mechanical obstruction. According to a neutrophil count cut-off determined by receiver operating characteristic curve analysis, patients were divided into two groups: group A (neutrophil count < 9.14 × 109/L) and group B (neutrophil count ≥ 9.14 × 109/L).Results.Compared to patients in the normal reflow group, patients with no-reflow had higher neutrophil counts (P<0.05). The incidence rate of no-reflow in group A (18, 9.3%) was significantly lower than that in group B (38). Multivariate logistic regression analysis revealed that a neutrophil count ≥ 9.14 × 109/L was independently predictive for no-reflow (odds ratio = 4.474, 95% confidence interval: 1.610–12.433,P=0.004) after adjusting for potential confounders.Conclusions.A circulating neutrophil count ≥ 9.14 × 109/L is independently associated with no-reflow in patients with acute STEMI following primary PCI.

Abstract Objectives To assess the evolution of hospital discharge management, 6 months hospitalization and mortality over the years of all patients admitted with ST segment elevation myocardial infarction (STEMI) in Portugal. Methods A nationwide electronic prospective registry that included all patients admitted to Portuguese hospitals with a diagnosis of Acute Coronary Syndrome since 2002 until 2018 was used to collect all data relative to patients admitted with a STEMI diagnosis during that time frame. Data on demographic data, clinical status, revascularization strategy, discharge medication and 6 months hospitalization and mortality were obtained. We compared the data and its evolution over the years to assess for trends. For statistical analysis, Qui-square tests were used to assess trends in categorical variables, and Kruskal-Wallis tests were used to assess trends in numerical variables. A p-value &lt;0.05 was considered statistically significant. Results During the study, a total of 23807 patients were admitted for STEMI in Portuguese hospitals, 74.3% were male and average age of 63.9±13.6 years. We report a progressive and significant increase the use of primary angioplasty versus fibrinolysis (24.3% to 98.4%, p&lt;0.001), in coronary angioplasties (36.4% to 73.2%, p&lt;0.001), in the use of drug-eluting stents (0% to 70.1%, p&lt;0.001), and a decrease in the patients that underwent surgery (6.8% to 1.3%, p&lt;0.001) and intra-aortic balloon pump (1.8% to 0%, p=0.009), resulting in a decrease in in-hospital mortality from 9.9% to 6.1% (p&lt;0.001). At discharge, we report a progressive increase in the prescription of P2Y12 inhibitors (21.1% to 95.2%, p&lt;0.001), beta-blockers (68.8% to 83.8%, p&lt;0.001), RAAS inhibitors (69.5% to 86.7%, p&lt;0.001) and statins (79.6% to 94.9%, p&lt;0.001), while the prescription of aspirin (94.1% para 94.8%, p=0.428), calcium channel blockers (5.3% to 5.6%, p&lt;0.684) stayed stable, and there was a decrease in the prescription of nitrates (52.9% to 5.8%, p&lt;0.001). Hospital admissions at 6 months consistently and progressively reduced over time (18.6% to 8.5%, p&lt;0.001) as well as mortality (6.7% para 4.3%, p&lt;0.001). Conclusion Post discharge treatment of STEMI patients in Portuguese hospitals has evolved according to guidelines, with higher prescription of medication proven to reduce outcomes, resulting in lower hospitalization rates and mortality. 6 Month Outcomes over the years Funding Acknowledgement Type of funding source: Public Institution(s).

Objective: To evaluate the feasibility and outcomes of primary percutaneous coronary intervention (PCI) as a mode of treatment in acute ST segment elevation myocardial infarction (STEMI). Study Design: Descriptive cross sectional study. Place and Duration of Study: The study was conducted in Army Cardiac Center Lahore, from Nov 2019 to Feb 2020. Methodology: All patients diagnosed as acute ST-segment elevation myocardial infarction during the study period were offered primary percutaneous coronary intervention among treatment options. Patients who chose primary percutaneous coronary intervention were included in the study. Informed consent was taken. Patient demographics, risk factors, time variables, procedural characteristics and in-hospital adverse events were evaluated. Results: On admission, Out of 50, 30 (60%) of the patients were current smokers, 25 (50%) were hypertensive, 22 (44%) were diabetic, and 1 (2%) had cardiogenic shock. The mean time from symptom onset to hospital arrival was 5 hours and the mean door-to-balloon time was 34 minutes. Culprit coronary artery was the left anterior descending artery (LAD) in 56% cases and multi-vessel disease was present in 38% cases. Primary percutaneous coronary intervention involved balloon dilatation (2%) and stent implantation (98%). The incidence of postprocedural angiographic no-reflow was 0%. All-cause mortality was 1%. Conclusion: This study has shown efficiency, feasibility and safety in performing of primary percutaneous coronary intervention with excellent outcomes in Army Cardiac Center Lahore. In order to further improve its outcomes, our goal should be to decrease reperfusion time which can be achieved by reducing patient delay, increasing public awareness and improving the management of first medical contact.

Abstract Background Microvascular obstruction (MVO) is a phenomenon that occurs frequently even after primary coronary intervention with recanalization of the infarct-related artery (IRA) and it has been shown to increase the risk of adverse cardiovascular events in ST-segment elevation myocardial infarction (STEMI) patients. The most important clinical predictor of MVO is ischemia duration, but there is a lack of information regarding predictor factors in promptly revascularized patients. Methods From January 2007 to October 2017, 1022 patients with STEMI that underwent urgent coronary angiography were retrospectively enlisted. We included 760 patients that were revascularized in ≤6 hours from symptom onset. Clinical, echocardiographic and angiographic data were taken from hospital records. A multivariate Cox regression analysis was made to assess the relationship between MVO (defined as final TIMI <3 in IRA) and potential predictors. Results From the 760 patients included, 73.7% were male and the mean age was 64.8±14.2 years. LVEF at admission was 46.1±12% and Killip class at admission was III-IV in 12.8% of the cases. The mean time between symptom onset and wire crossing was 3.3±1.3 hours. MVO was found in 130 cases (17.2%). After the multivariate Cox regression analysis, Killip class III-IV at admission was associated with MVO (OR 2.87 [1.31–6.31]). No other clinical variables were independently associated with the occurrence of MVO. The angiographic and interventional variables with a significant association with MVO were: predilatation (OR 1.87 [1.003–3.49]), postdilatation (OR 0.49 [0.27–0.89]), stent length (OR 1.04 [1.001–1.08]), stent diameter (OR 1.89 [1.11–3.23]), thrombus burden of the culprit lesion (OR 2.69 [1.26–5.71]) and distal embolization (OR 5.52 [2.79–10.89]). Conclusions In early presenters of STEMI, angiographic and interventional variables were more important as predictors of MVO than clinical variables. Killip class III-IV at admission was a clinical predictor factor for MVO in this population. Prospective studies are needed to confirm these results.
