Abstract Background It has been reported that the lumen factors of the culprit lesions are related to Thrombolysis in Myocardial Infarction (TIMI) flow grade in ST-Segment–Elevation Myocardial Infarction (STEMI) patients, but the factors of reduced TIMI flow in plaque erosion have not been studied. Methods 329 STEMI patients with plaque erosion who underwent pre-intervention optical coherence tomography after thrombectomy were included and divided into 2 groups according to preprocedural TIMI flow grade [TIMI 0–1 (n=219) and TIMI 2–3 (n=110)]. Results The patients with older age (55.7±11.1yrs vs. 51.8±10.6yrs, P=0.003) and diabetes patients (18.3% vs. 8.2%, P=0.015) had poorer TIMI flow, and the patients with reduced TIMI flow grade have lower initial cTnI (1.2ng/mL vs. 2.1ng/mL, P=0.023). The lesion in the LAD had better blood flow than the lesion in RCA (P=0.003), and the patients in TIMI 0–1 grade had more lipid plaques (53.9% vs. 41.8%, P=0.039), more macrophage (59.8% vs. 41.8%, P=0.002), and more calcification (34.2% vs. 21.8%, P=0.020). There was no statistically significant difference in the descriptive indicators of lipid or lumen between the two groups. And In a multivariate logistic regression model, the independent correlation factors of reduced TIMI flow grade in erosion patients were age, diabetes mellitus, lesion vessel, and macrophage. Conclusions In STEMI patients with plaque erosion non-lumen factors greatly affect flow, which suggests that systemic treatment is as important as local treatment for plaque erosion.

Background: Doing percutaneous coronary intervention (PCI) in the first hours of myocardial infraction (MI) is effective in re-establishment of blood flow. Anticoagulation treatment should be prescribed in patients undergoing PCI to decrease the side effects of ischemia. The aim of this study is to determine the effect of heparin prescription after PCI on short-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). Materials: This randomized clinical trial study was conducted at Imam Ali cardiovascular center at Kermanshah university of medical science (KUMS), Iran. Between April 2019 to October 2019, 400 patients with STEMI which candidate to PCI were enrolled. Patients randomly divided in two groups: intervention group (received 5,000 units of heparin after PCI until first 24 hours, every 6 hours) and control group (did not receive heparin). Data were collected using a checklist developed based on the study's aims. Differences between groups were assessed using independent t-tests and chi-square (or Fisher exact tests).Result: Observed that, mean prothrombin time (PT) (13.30±1.60 vs. 12.21±1.15, p<0.001) and partial thromboplastin time (PTT) (35.30±3.08 vs. 34.41±3.01, p=0.003) were significantly higher in intervention group compared to control group. Thrombolysis in myocardial infarction (TIMI) flow grade 0/1 after primary PCI was significantly more frequently in control group (5.5% vs. 1.0%, p=0.034). The mean of ejection fraction (EF) after PCI (47.58±7.12 vs. 45.15±6.98, p<0.001) was significantly higher in intervention group. Intervention group had a statistically significant shorter length of hospital stay (4.71±1.03 vs. 6.12±1.10, p<0.001). There was higher incidence of re-vascularization (0% vs. 3.0%; p=0.013) and re-MI (0% vs. 2.5%; p=0.024) in the control group.Conclusion: Performing primary PCI with receiving heparin led to improve TIMI flow and consequently better EF. Receiving heparin is associated with lower risk of re-MI and re-vascularization.

Abstract Background: Studies comparing long-term clinical outcomes between prediabetes and diabetes based on pre-percutaneous coronary intervention (PCI) Thrombolysis in Myocardial Infarction (TIMI) flow grade in patients with ST-segment elevation myocardial infarction (STEMI) after successful PCI with newer-generation drug-eluting stents are limited. We compared 2-year clinical outcomes of these two groups. Methods: Overall, 6448 STEMI patients were divided into two groups: pre-PCI TIMI 0/1 group (n = 4854) and pre-PCI TIMI 2/3 group (n = 1594). Subsequently, these two groups were further divided into patients with normoglycemia, prediabetes, and type 2 diabetes mellitus (T2DM). The major endpoint was the occurrence of major adverse cardiac events (MACEs), defined as all-cause death, recurrent myocardial infarction, or any repeat revascularization. Results: After adjustment, in the pre-PCI TIMI 0/1 group, the cumulative incidence of all-cause death was higher in both prediabetes (adjusted hazard ratio [aHR]: 1.633, p = 0.045) and T2DM (aHR: 2.064, p = 0.002) groups than in the normoglycemia group. In the pre-PCI TIMI 2/3 group, the cumulative incidence of any repeat revascularization was higher in both prediabetes (aHR: 2.511, p = 0.039) and T2DM (aHR: 3.156, p = 0.009) groups than in the normoglycemia group. However, in each group (pre-PCI TIMI 0/1 or 2/3), the cumulative incidences of MACEs and all other clinical outcomes were not significantly different between the prediabetes and T2DM groups. Conclusions: In this retrospective registry study, prediabetes showed worse clinical outcomes similar to those of T2DM regardless of the pre-PCI TIMI flow grade. However, further studies are warranted to confirm these results.

Background: Previous studies, published before the advent of primary reperfusion, described the electrocardiographic features of ST-segment elevation myocardial infarction (STEMI) caused by total diagonal artery occlusion, as demonstrated at pre-discharge coronary angiography. We aimed to assess the electrocardiographic and echocardiographic features in STEMI unequivocally attributed to a diagonal lesion in the era of primary coronary intervention. Methods: The electrocardiograms and echocardiograms of patients sustaining STEMI caused by diagonal artery involvement were compared with those of patients with STEMI attributed to proximal or mid left anterior descending artery (LAD) lesions. ST-segment deviations were measured at four different points in each lead and analyzed against TIMI flow and SNuH score. The electrocardiographic and echocardiographic features of each group were mapped. Results: In contrast to previous studies claiming an ever-present incidence of at least 1-mm ST-segment elevation in leads I and aVL with diagonal STEMI, we report 86% of any ST-elevation in leads I, aVL and V2 (64–71% for ST-elevation >1 mm). Both higher SNuH score and pre-intervention TIMI flow were associated with larger lateral ST-elevations (85.7% and 86.4–95.5%, respectively). Higher prevalence of ST-depression in the inferior leads reflecting reciprocal changes was observed in patients with diagonal-induced STEMI (57–76% vs. 24–51% in LAD obstructions, p <0.05). Conclusion: The most sensitive and predictive sign for acute ischemia was any degree of ST-deviation measured 1 mm beyond the J point. ST-elevations in I, aVL and V2, sparing V3-V5, strongly favor isolated diagonal lesion. Proximal LAD lesion lacking ST-segment elevations in leads I and aVL is primarily due to wraparound LAD anatomy.

Abstract Introduction A relevant proportion of patients experiencing ST-segment elevation myocardial infarction (STEMI) has a late presentation after symptoms onset. Temporal trends deriving from a large real-word scenario for this subgroup of patients are lacking. Purpose The aim of the present study was to provide a comprehensive analysis of temporal trends in latecomer STEMI patients, with particular regard to implementation of evidence-based treatments in this population and major in-hospital outcomes. Methods All STEMI patients included in the AMIS Plus Registry from January 1997 to December 2017 were included and patient-related delay was assessed: 27 231 patients were available for the final analysis. STEMI patients were classified as early or latecomers according to patient-related delay (≤ or >12 hours, respectively). Results 22 928 patients were earlycomers (84%) and 4303 patients were classified as latecomers (16%). Across the study period we observed a significant decrease in prevalence of late presentation from 22% to 12.3% (p<0.001, Figure 1). In latecomer STEMI patients there was a gradual uptake of evidence-based pharmacological treatments with an increase in discharge prescription of P2Y12 inhibitors from 6% to 90.7% (p<0.001). Similarly, a marked increase in percutaneous coronary intervention (PCI) rate was observed (12.1–86.6%; p<0.001). Across this 20-year period, in-hospital mortality was reduced to a third (to an absolute rate of 4.5%, p<0.001) and a significant reduction in prevalence of both cardiogenic shock (14.6–4.3%) and re-infarction (5.4–0.2%) during the index hospitalisation was observed (p<0.001 for both variables). Length of hospitalisation in acute care facilities significantly decreased from 10 (6,14) days to 4 (1,7) days (p<0.001). At multivariate analysis, PCI had a strong independent protective effect toward in-hospital mortality (odds ratio 0.3, 95% confidence interval 0.187 to 0.480). Figure 1 Conclusion The present study provides a comprehensive picture of temporal trends in late presentation in STEMI over the last 20 years in Switzerland. During the study period in latecomer STEMI population there was a gradual uptake of evidence-based pharmacological treatments and a marked increase in PCI rate. In-hospital mortality was reduced to a third (to an absolute rate of 4.5%) and this reduction seems to be mainly associated with the increasing implementation of PCI.
