Abstract Purpose: Trimetazidine, a metabolic agent with anti-ischemic effects, was reported to reduce reperfusion injury in animal models. In this randomized double-blind placebo-controlled trial, we investigated the effects of trimetazidine on reducing infarction size in patients undergoing revascularization for ST-segment elevation myocardial infarction (STEMI). Methods: Patients with STEMI randomly received trimetazidine (n=87) or placebo (n= 86) in a double-blind manner before primary percutaneous coronary intervention (PCI), and study treatment was maintained for 12 months after the procedure. The primary endpoint was infarction size measured by cardiac magnetic resonance (CMR) after primary PCI. Results: The clinical characteristics of patients (90% male, mean age 57±12 years) in both groups were well-matched on the baseline. Compared with patients in control group, the percentage and weight of infarction size of patients in trimetazidine group were both significantly lower (22.1±11.8% [n =74] vs. 26.9±11.9% [n=74], p=0.010; 28±18g [n =74] vs. 35±19g [n=74], p=0.022), the myocardial microvascular obstruction (MVO) rate measured by CMR was lower in trimetazidine group (29.7% [22/7] vs. 52.7% [39/74], p=0.007), while myocardial salvage index (MSI) was significantly higher in trimetazidine group (48±20% vs. 39±27%, p=0.008). The incidence of readmission due to aggravated heart failure in trimetazidine group was lower than that in the control group without significance (8.0% vs 14.0%, p=0.234). Conclusions: Our study provides suggests that trimetazidine initiated prior to primary PCI, improves myocardial infarct size, MVO and MSI, possibly by reducing reperfusion injury.

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.

The aim – to investigate associations between macrophage inhibitory factor (MIF) and anxiety, depression and stress in patients with ST-segment elevation myocardial infarction (STEMI). Materials and methods. 73 patients with STEMI with TIMI-III aged 58.37±10.34 were enrolled in the study. Revascularization tactics distribution was the following: 43 (58.9 %) patients underwent primary percutaneous coronary intervention using bare-metal coronary stent, 30 (41.1 %) – pre-hospital thrombolysis with subsequent percutaneous coronary intervention within12 hours. Echocardiography was done during the period of hospitalization. Serum MIF was studied using the enzyme linked immunoassay method. Anxiety, depression and stress were determined with DASS-21 questionnaire. Results and discussion. When comparing the median values of the MIF level in STEMI patients, a statistically significant increase in the MIF concentration relative to control group (2582.80 [1308.40–4122.20] and 573.75 [397.80–1016.75] ng/ml, p<0.001). It evidences the activation of the formation of MIF after the index event. Positive correlation was determined between the level of MIF, the level of troponin I (r=0.33; р=0.045) and blood leukocytes (r=0.36; р=0.039) that confirms its involvement into inflammation and necrosis processes. The univariant and multivariate analysis revealed the effect of the degree of depression and anxiety growth on the DASS-21 questionnaire (p=0.0138 and p=0.0050, respectively) on the increasing of the MIF. Conclusions. The data obtained confirm the relationship between the MIF and anxiety and depression prior the onset of myocardial infarction, indicating their influence on the processes of inflammation.

Abstract Background Long-term reports on reperfusion therapy for acute ST-segment elevation myocardial infarction (STEMI) in developing countries are scarce. Purpose We reported changes in acute reperfusion therapy for STEMI that have been observed over time in an academic tertiary care percutaneous coronary intervention (PCI) centre that hosting a STEMI network in the large metropolitan area of Jakarta, Indonesia since 2010 and covering around 11 million inhabitants. Methods A retrospective analysis was performed in 6336 patients with STEMI who admitted to the emergency department of a PCI centre in 2008 (before STEMI network introduction), and during 2011 to 2018. Results Among STEMI patients admitted during 2011–2018 (mean age: 56±10 years, 86% male), 57.6% had anterior wall myocardial infarction, and 71.3% presented with Killip classification I. Compared with the period 2011–2014 (N=2766), patients who were admitted in the period 2015–2018 (N=3250) were receiving more primary percutaneous coronary intervention (PCI) (61.6% vs. 44.2%, P&lt;0.001) with shorter door-to-device time (median 72 min versus 97 min, P&lt;0.001), and less in-hospital fibrinolytic therapy (2.7% vs. 4.8%, P&lt;0.001). The percentage of STEMI patients who did not receive reperfusion treatment decreased from 51% to 35.5% (P&lt;0.001). In-hospital mortality declined from 10% in 2008 (before the STEMI network was initiated) and 8% in 2011 to 6.4% in 2018 (P for trends = 0.05). Multivariable analysis showed that primary PCI was significantly associated with better in-hospital survival (adjusted odds ratio, 0.52; 95% confidence interval, 0.42 to 0.65, P&lt;0.001). Conclusion The data indicate that the introduction of a STEMI network resulted in more patients receiving timely primary PCI and lower early mortality rates in recent years.

Objective We aimed to determine whether the prognostic value of the shock index (SI) and its derivatives is better than that of the Thrombolysis In Myocardial Infarction risk index (TRI) for predicting adverse outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods A total of 257 patients with STEMI undergoing primary PCI from January 2018 to June 2019 were analyzed in a retrospective cohort study. The SI, modified shock index (MSI), age SI (age × the SI), age MSI (age × the MSI), and TRI at admission were calculated. Clinical endpoints were in-hospital complications, including all-cause mortality, acute heart failure, cardiac shock, mechanical complications, re-infarction, and life-threatening arrhythmia. Results Multivariate analyses showed that a high SI, MSI, age SI, age MSI, and TRI at admission were associated with a significantly higher rate of in-hospital complications. The predictive value of the age SI and age MSI was comparable with that of the TRI (area under the receiver operating characteristic curve: z = 1.313 and z = 0.882, respectively) for predicting in-hospital complications. Conclusions The age SI and age MSI appear to be similar to the TRI for predicting in-hospital complications in patients with STEMI undergoing primary PCI.

AbstractRoutine performance measures of primary percutaneous coronary intervention (PCI) within an ST-segment elevation myocardial infarction (STEMI) network are needed to improve care.We evaluated the door-in to door-out (DI–DO) delays at the initial hospitals in STEMI patients as a routine performance measure of the metropolitan STEMI network.We retrospectively analyzed the DI–DO time from 1,076 patients with acute STEMI who were transferred by ground ambulance to a primary PCI center for primary PCI between 4 October 2014 and 1 April 2019. Correlation analysis between DI–DO times and total ischemia time was performed using Spearman's test. Logistic regression analyses were used to find variables associated with a longer DI–DO time.Median DI–DO time was 180 minutes (25th percentile to 75th percentile: 120–252 minutes). DI–DO time showed a positive correlation with total ischemia time (r = 0.4, p < 0.001). The median door-to-device time at the PCI center was 70 minutes (25th percentile to 75th percentile: 58–88 minutes). Multivariate analysis showed that women patients were independently associated with DI–DO time > 120 minutes (odds ratio 1.55, 95% confidence interval 1.03 to 2.33, p = 0.03).The DI–DO time reported in this study has not reached the guideline recommendation. To improve the overall performance of primary PCI in the region, interventions aimed at improving the DI–DO time at the initial hospitals and specific threat for women patients with STEMI are possibly the best efforts in improving the total ischemia time.

Background: Hyperglycemia upon admission is associated with an increased risk for acute kidney injury (AKI) in ST segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI). However, the relation of this association to the absence of diabetes mellitus (DM) is less studied. We evaluated the effect of acute hyperglycemia levels on the risk of AKI among STEMI patients without DM who were all treated with primary PCI. Methods: We retrospectively studied 1,065 nondiabetic STEMI patients undergoing primary PCI. Patients were stratified according to admission glucose levels into normal (<140 mg/dl), mild (140-200 mg/dl), and severe (>200 mg/dl) hyperglycemia groups. Medical records were reviewed for the occurrence of AKI. Results: The mean age was 61 ± 13 years and 81% were males. Hyperglycemia upon hospital admission was present in 402 of 1,065 patients (38%). Patients with severe admission hyperglycemia had a significantly higher rate of AKI compared to patients with no or mild hyperglycemia (20 vs. 7 and 8%, respectively; p = 0.001) and had a significantly greater serum creatinine change throughout hospitalization (0.17 vs. 0.09 and 0.07 mg/dl, respectively; p = 0.04). In multivariate logistic regression, severe hyperglycemia emerged as an independent predictor of AKI (OR = 2.46, 95% CI 1.16-5.28; p = 0.018). Conclusion: Severe admission hyperglycemia is an independent risk factor for the development of AKI among nondiabetic STEMI patients undergoing primary PCI.

BACKGROUND Performing primary percutaneous coronary intervention (PCI) as a preferred reperfusion strategy for patients with ST-segment elevation myocardial infarction (STEMI) may be associated with major adverse cardiocerebrovascular events (MACCEs). Thus, timely primary PCI has been emphasized in order to improve outcomes. Despite guideline recommendations on trying to reduce the door-to-balloon time to &lt;90 minutes in order to reduce mortality, less attention has been paid to other components of time to treatment, such as the symptom-to-balloon time, as an indicator of the total ischemic time, which includes the symptom-to-door time and door-to-balloon time, in terms of clinical outcomes of patients with STEMI undergoing primary PCI. OBJECTIVE We aimed to determine the association between each component of time to treatment (ie, symptom-to-door time, door-to-balloon time, and symptom-to-balloon time) and in-hospital MACCEs among patients with STEMI who underwent primary PCI. METHODS In this observational study, according to a prospective primary PCI 24/7 service registry, adult patients with STEMI who underwent primary PCI in one of six catheterization laboratories of Tehran Heart Center from November 2015 to August 2019, were studied. The primary outcome was in-hospital MACCEs, which was a composite index consisting of cardiac death, revascularization (ie, target vessel revascularization/target lesion revascularization), myocardial infarction, and stroke. It was compared at different levels of time to treatment (ie, symptom-to-door and door-to-balloon time &lt;90 and ≥90 minutes, and symptom-to-balloon time &lt;180 and ≥180 minutes). Data were analyzed using SPSS software version 24 (IBM Corp), with descriptive statistics, such as frequency, percentage, mean, and standard deviation, and statistical tests, such as chi-square test, <i>t</i> test, and univariate and multivariate logistic regression analyses, and with a significance level of &lt;.05 and 95% CIs for odds ratios (ORs). RESULTS Data from 2823 out of 3204 patients were analyzed (mean age of 59.6 years, SD 11.6 years; 79.5% male [n=2243]; completion rate: 88.1%). Low proportions of symptom-to-door time ≤90 minutes and symptom-to-balloon time ≤180 minutes were observed among the study patients (579/2823, 20.5% and 691/2823, 24.5%, respectively). Overall, 2.4% (69/2823) of the patients experienced in-hospital MACCEs, and cardiac death (45/2823, 1.6%) was the most common cardiac outcome. In the univariate analysis, the symptom-to-balloon time predicted in-hospital MACCEs (OR 2.2, 95% CI 1.1-4.4; <i>P</i>=.03), while the symptom-to-door time (OR 1.4, 95% CI 0.7-2.6; <i>P</i>=.34) and door-to-balloon time (OR 1.1, 95% CI 0.6-1.8, <i>P</i>=.77) were not associated with in-hospital MACCEs. In the multivariate analysis, only symptom-to-balloon time ≥180 minutes was associated with in-hospital MACCEs and was a predictor of in-hospital MACCEs (OR 2.3, 95% CI 1.1-5.2; <i>P</i>=.04). CONCLUSIONS A longer symptom-to-balloon time was the only component associated with higher in-hospital MACCEs in the present study. Efforts should be made to shorten the symptom-to-balloon time in order to improve in-hospital MACCEs. INTERNATIONAL REGISTERED REPORT RR2-10.2196/13161
