Abstract Aims Myocardial perfusion could determine the outcome of patients with ST-segment elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PPCI). The aim of this study was to evaluate the impact of colchicine on myocardial perfusion in this population. Methods In a double-blind, randomized trial, we assigned 196 patients with STEMI undergoing PCI to two groups: the colchicine group (N=95) and the control group (N=101). The primary endpoints were the thrombolysis in myocardial infarction (TIMI) score; TIMI myocardial perfusion grade (TMPG), and TIMI frame count (TFC). The major adverse cardiovascular events (MACEs) were recorded after one month of PPCI. Results The Final TIMI flow grade, TMPG and TFC were not significantly different between the 2 groups (p=0.75, p=0.533, p=0.161; respectively). MACE include Mortality, Non-fatal myocardial infarction, target lesion/vessel revascularization were similar between the 2 groups (p=0.058). Study outcomes Characteristics Colchicine Group (n=95) Control Group (n=101) P value Discharge status   Deceased 2 (2.1%) 2 (2%) 1   Alive 93 (97.9%) 99 (98%) TIMI flow grade after PCI   0 2 (2.1%) 1 (1%) 0.747   1 2 (2.1%) 4 (4%)   2 17 (17.9%) 21 (20.8%)   3 74 (77.9%) 75 (74.3%) TIMI myocardial perfusion grade 2.39±0.89 2.31±0.95 0.533 ST segment resolution   Below 50 Percentage 23 (27.1%) 27 (32.1%) 0.71   Between 50 to 70 Percentage 8 (9.4%) 6 (7.1%)   Above 70 Percentage 54 (63.5%) 51 (60.7%)   MACE.1.Month 10 (9.9%) 3 (3.2%) 0.058   MACE.1.Month(Mortality) 4 (4.0%) 2 (2.1%) 0.451   MACE.1.Month(Non.Fatal.MI) 2 (2.0%) 0 (0%) 0.168   MACE.1.Month(TLR) 2 (2.0%) 1 (1.1%) 0.597   MACE.1.Month(TVR) 5 (5.0%) 1 (1.1%) 0.113 Conclusion In STEMI patients treated by PPCI, the effect of colchicine before PPCI was not revealed on myocardial perfusion markers.

Abstract Aim and objectives The aim of this study was to assess the impact of high intensity statins used prior to primary PCI in patients presenting with acute STEMI (ST-elevation Myocardial Infarction) on myocardial perfusion and in-hospital MACE (major adverse cardiac events). Patients and Methods The study included 170 patients who presented with acute STEMI to the cardiology department of Ain Shams university hospitals and underwent primary PCI (percutaneous coronary intervention). They were divided into two groups where the first group received high intensity statins (40-80mg of atorvastatin or 20-40mg of rosuvastatin) besides guideline recommended therapy before primary PCI and the 2nd group served as a control group and received guideline recommended therapy, and high intensity statins after going back to the coronary care unit after primary PCI. Post interventional thrombolysis in myocardial infarction (TIMI) flow grade and myocardial blush grade (MBG) were recorded and ST-segment resolution was measured. Results The majority of patients in both groups had the LAD as the culprit vessel for their presentation. In the control group there were 4 patients with TIMI I flow and MBG I, 13 with TIMI II flow and MBG II and 68 with TIMI III flow and MBG III. Meanwhile in the cases group there was 1 patient with TIMI I flow and MBG I, 3 with TIMI II flow and MBG II and 81 with TIMI III flow and MBG III. This difference was statistically significant with a P value of 0.010. There were 34 patients in the cases group who showed complete ST-segment resolution (40%) vs 19 patients (22.4%) in the control group which was statistically significant with a P value of 0.013. In addition, ejection fraction measured by M-mode had values of Mean+-SD of 45.91 ± 5.49 in cases group vs 43.01 ± 8.80 in control group which was statistically significant with a P value of 0.011. There was not a statistically significant difference between the two groups regarding in-hospital death of all causes and stroke after primary PCI. Conclusion High intensity statin loading before primary PCI resulted in improved post-procedural TIMI flow, MBG, complete ST-segment resolution and ejection fraction as measured by M-mode but did not decrease incidence of in-hospital MACE.

Abstract Background: The no-reflow phenomenon (NRP) is an important factor affecting the prognosis of patients with acute myocardial infarction undergoing primary percutaneous coronary intervention (PPCI). This study aims to investigate the association of circulating miR-660-5p with NRP in patients with ST segment elevation myocardial infarction (STEMI) undergoing PPCI.Methods: Consecutive patients diagnosed with anterior STEMI within 12 h of pain onset were included in the study; in these patients, coronary angiography confirmed that the infarct-related artery was the left anterior descending (LAD) artery. Angiographic NRP was defined as a final TIMI flow of 2 or a final TIMI flow of 3 with a myocardial blush grade (MBG) < 2. High miR-660-5p was defined as a value in the third tertile. The relationship of circulating miR-660-5p with NRP was assessed using Spearman correlation analysis and multiple logistic regression analysis.Results: Fifty-two eligible patients were finally included in this study (mean age: 56±12.4 years, >65 years: 53.8%, male: 76.9%, and mean BMI: 26.3±3.5). The incidence of NRP was 38.5%. Circulating miR-660-5p was significantly related to the mean platelet volume (MPV). Patients were divided into tertiles by miR-660-5p levels (Q1: ≤ 7.18, Q2: 7.18-11.31, Q3: > 11.31). Patients in the high microRNA-660-5p group had almost a 6-fold higher risk of NRP than those in the low microRNA-660-5p group [(odds ratio (OR)=5.68, 95% confidence interval (CI) 1.40-23.07, p=0.015). When analysed by tertiles, consistent trends of an increasing relative odds of NRP were reported (OR1 for Q2 VS. Q1: 1.25, 95% CI: 0.27-5.73, p=0.77; OR2 for Q3 VS. Q1: 5.96, 95% CI: 1.33-26.66, p=0.02), even after multivariable adjustment. Receiver operating characteristic curve analysis demonstrated that the microRNA-660-5p level of 10.17 was the best cut-off level to predict the incidence of the no-reflow phenomenon in patients undergoing primary percutaneous coronary intervention with an area under the curve (AUC) of 0.768 (95% CI: 0.636-0.890).Conclusion: Circulating miR-660-5p was significantly associated with NRP, and it may be a useful biomarker to predict the incidence of NRP in patients with STEMI undergoing PPCI.

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.

Aim: No-reflow phenomenon (NRP) is an undesirable result of coronary interventions, and usually occurred during the primary percutaneous coronary intervention (PPCI). On the other hand, there is growing evidence of epidemiological studies suggest that serum 25 hydroxy-vitamin D (25(OH)D3) level is significantly associated with cardiovascular mortality and morbidity. Objective: To investigate whether there is a relationship between admission serum 25(OH)D3 levels and NRP in patients with ST elevation myocardial infarction (STEMI). Methods: This study consisted of 496 consecutive acute STEMI patients who underwent PPCI. After the restoration of antegrade flow, the patients were divided into the normal flow and no-reflow groups. No-reflow defined as; thrombosis in myocardial infarction (TIMI) flow grade ≤2, or a TIMI flow grade = 3 with a myocardial perfusion grade ≤1. Results: Angiographic no-reflow occurred 18.2% of all study patients. Serum 25(OH)D3 levels were significantly lower when compared with the normal flow group (14.6 ± 7.3 vs 22.6 ± 9.6 ng/ml; p < 0.001). 25(OH)D3 level was significantly negatively correlated with Neutrophil/lymphocyte (N/L) ratio. In multivariate analysis, 25(OH)D3 level on admission (OR: 0.738; 95% CI: 0.584–0.878; p = 0.001) was found an independent predictor of NRP together with N/L ratio, N-Terminal-proBNP, balloon pre dilatation and syntax score I. On receiver operating curve analysis (ROC), the cut-off value of admission 25(OH)D3 level was 10.5 ng/ml for the prediction of NRP with a sensitivity of 93% and specificity of 68%. The area under the ROC curve (AUC) was 0.772 (95% CI: 0.697–0.846; p < 0.001). Conclusion: We have shown that lower 25(OH)D3 level on admission is associated with higher NRP frequency and may be used as a predictor for NRP in STEMI patients undergoing PPCI.

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.

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 Aims Whether patients with spontaneous coronary artery dissection (SCAD) should undergo an initial conservative management or immediate revascularization through percutaneous coronary intervention (PCI) remains debated. To investigate the frequency and predictors of choosing a strategy of immediate PCI for SCAD, and to compare the clinical outcomes of immediate PCI patients with those undergoing an initial strategy of medical management. Methods and results 369 patients enrolled in the multicentre international DIssezioni Spontanee COronariche (DISCO) registry between January 2009 and December 2020 were included. The primary endpoint was major adverse cardiovascular events (MACE), a composite of cardiac death, non-fatal myocardial infarction (MI) and any PCI. 240 (65%) patients underwent initial medical management, whereas 129 (35%) had immediate PCI. PCI patients presented more frequently with ST segment-elevation myocardial infarction (STEMI) (68.2% vs. 35%, P &lt; 0.001) and had higher frequency of proximal coronary segment SCAD (31.8% vs. 6.7%, P &lt; 0.001), Thrombolysis in Myocardial infarction (TIMI) flow grade 0–1 (54.3% vs. 20.4%, P &lt; 0.001) and multivessel SCAD (18.6% vs. 9.2%, P = 0.015), as well as a more severe diameter stenosis [99% (100–90) vs. 90% (99–75), P &lt; 0.001]. At multivariate logistic regression, STEMI at presentation (vs. NSTE-ACS, OR: 3.30 95% CI: 1.56–7.12, P = 0.002), proximal coronary segment involvement (OR: 5.43, 95% CI: 1.98–16.45, P = 0.002), TIMI flow grade 0–1 and 2 (respectively, vs. grade 3: OR: 3.22 95% CI: 1.08–9.96, P = 0.038; and OR: 3.98; 95% CI: 1.38–11.80, P = 0.009) and diameter stenosis (per 5% increase, OR: 1.13; 95% CI: 1.01–1.28, P = 0.037) were predictors of immediate PCI, whereas the angiographic subtype 2B predicted a conservative approach (OR: 0.25; 95% CI: 0.07–0.83, P = 0.026). The frequency of in-hospital major adverse cardiac events did not differ between medically and PCI-treated patients. At 2-year follow-up, there were no differences with respect to the composite of MACE (11.7% vs. 13.9%, P = 0.47) and the individual components of cardiovascular death (0.4% vs. 0.7%, P = 0.65), non-fatal MI (8.3% vs. 9.3%, P = 0.92), and any PCI (8.7% vs. 12.4%, P = 0.23). Conclusions The choice between an immediate medical or PCI management of SCAD is mostly driven by clinical presentation and procedural aspects. In the DISCO cohort, the primary treatment approach was not associated with the risk of short-to-midterm adverse events.

Background. The study aimed to verify the effect of primary percutaneous coronary intervention (PPCI) with <60 min door-to-balloon time on ST segment elevation myocardial infarction (STEMI) patients’ prognoses. Methods. Outcomes of patients receiving PPCI with door-to-balloon time of <60 min were compared with those of patients receiving PPCI with door-to-balloon time 60–90 min. Result. Totally, 241 STEMI patients (191 with Killip classes I or II) and 104 (71 with Killip classes I or II) received PPCI with door-to-balloon time <60 and 60–90 min, respectively. Killip classes I and II patients with door-to-balloon time <60 min had better thrombolysis in myocardial infarction (TIMI) flow (9.2% fewer patients with TIMI flow <3, p=0.019) and 8.0% lower 30-day mortality rate (p<0.001) than those with 60–90 min. After controlling the confounding factors with logistic regression, patients with door-to-balloon time <60 min had lower incidences of TIMI flow <3 (aOR = 0.4, 95% CI = 0.20–0.76), 30-day recurrent myocardial infarction (aOR = 0.3, 95% CI = 0.10–0.91), and 30-day mortality (aOR = 0.3, 95% CI = 0.09–0.77) than those with 60–90 min. Conclusion. Door-to-balloon time <60 min is associated with better blood flow in the infarct-related artery and lower 30-day recurrent myocardial infarction and 30-day mortality rates.
