Introduction: About one-fourth of patient with acute coronary syndrome present with transient ST-elevation myocardial infarction (STEMI). No specific recommendations exist in current guidelines regarding the timing of intervention for such patients due to lack of high-quality randomized trials. Methods: The Cochrane library and PubMed databases were searched for relevant studies. Two authors independently screened and included studies that were randomized controlled trials or observational studies comparing early with delayed invasive strategies in transient STEMI. Efficacy outcomes included target vessel revascularization, reinfarction and recurrent ischemia rates. Primary safety outcome was major bleeding. Random-effects model was used for pooled calculation of odds ratio (OR). Results: Out of all studies found, only 4 studies were included in our analysis (295 patients in early intervention group and 307 patients in delayed intervention group). Delayed intervention was associated with significant increase in all-cause mortality (OR: 2.81 [1.39-5.68], I 2 = 0%, p value = 0.004) (Figure 1). We did not find any significant difference in reinfarction rate (OR: 0.75 [0.12-4.66], I 2 = 0%, p value = 0.75), target vessel revascularization rate (OR: 0.66 [0.11-4.14] I 2 = 0%, p value = 0.66) and recurrent ischemia rate (OR 1.52[0.40-5.84], I 2 = 18 %, p value = 0.54). In addition, major bleeding rate was also similar in both groups (OR 0.68 [0.25-2.25], I 2 = 12%, p value = 0.60). Conclusions: This low to moderate-quality evidence suggests that early invasive strategy might reduce the mortality rate in transient STEMI. There is need of well-designed large randomized studies to gather further evidence regarding the best management of transient STEMI.

Background: The selection of β-blocker for survivors after primary intervention due to acute ST-elevation myocardial infarction seems crucial to improve the outcomes. However, rare comparison data existed for these patients. We aimed to compare the effectiveness of selective β-blockers to that of carvedilol in patients treated with primary intervention. Methods and results: Among the 1,485 patients in the “INTERSTELLAR” registry between 2007 and 2015, 238 patients with selective β-blockers (bisoprolol, nebivolol, atenolol, bevantolol, and betaxolol) and 988 with carvedilol were included and their clinical outcomes were compared for a 2-year observation period. In the clinical baseline characteristics, the unfavorable trends in the carvedilol group were high Killip presentation, lower ejection fractions, smaller diameters, and longer lengths of deployed stents. Although mortality (2.5% vs. 1.7%; p = 0.414) and the rate of stroke (0.8% vs. 0.6%; p = 0.693) were not different between groups, the rate of recurrent myocardial infarction (4.6% vs. 1.2%; p = 0.001) and of target vessel revascularization (4.2% vs. 0.9%; p < 0.001) were lower in the carvedilol group. After eliminating the difference by propensity matching, the similar outcome result was shown (all-cause death, 0.6% vs. 1.0%, p = 0.678; stroke, 0.6% vs. 1.2%, p = 0.479; myocardial infarction, 5.0% vs. 1.2%, p = 0.003; target vessel revascularization, 4.5% vs. 0.7%, p < 0.006) for 595 matched populations. The use of carvedilol was also determined to be an independent predictor for recurrent myocardial infarctions (hazard ratio = 0.305; p = 0.005; 95% confidence interval = 0.13-0.69). Conclusion: Use of a carvedilol in ST-segment myocardial infarction survivor is associated with lower recurrent myocardial infarction events. Thus, it might be the better choice of β-blocker for secondary prevention in ST-elevation myocardial infarction patients treated with primary percutaneous coronary intervention.

Abstract Background More than 40% of patients with non-ST Elevation Myocardial Infarction (NSTEMI) have multi-vessel disease with the rate of in-hospital emergent bypass surgery ranging from 11–13%. So, rapid scoring is critical for optimum management even before P2Y12 loading. Purpose We aimed to determine the role of QRS dispersion at emergency department, as a simple and rapid sign, in predicting coronary anatomy complexity and in-hospital outcome. Methods 192 (126 males, age 57.4±6.8 years) patients with NSTEMI and QRS duration <120 ms who underwent coronary angiography were included. QRS dispersion was automatically measured. Results Using Spearman's rank correlation, SYNTAX score was found to be positively correlated with admission HR (r 0.54, p value <0.001), maximum HsTnT level (r 0.523, p value <0.001), age (r 0.262, p value 0.015), male gender (r 0.286, p value 0.005), QRS dispersion (r 0.248, p value 0.015), QTc dispersion (r 0.289, p value 0.01), and Grace score (r 0.247, p value 0.015). ROC curve analyses for prediction of SYNTAX score >33 were done for variables with significant correlation. By multivariate logistic regression, male gender (OR 5.042, 95% CI 1.633 –15.567, p value 0.005), admission HR >80 bpm (OR 1.088, 95% CI 1.024 –1.157, p value 0.017) and QRS dispersion >20ms (OR 1.020, 95% CI 1.003 –1.037, p value 0.02) were independent predictors of SYNTAX score >33 (table). Patients with QRS dispersion >20 ms had in-hospital higher Killip class (P<0.001), recurrent ischemia (P 0.003), serious ventricular arrhythmias (P 0.01) and higher GRACE score (P<0.001). Binary logistic regression for prediction of SYNTAX score >33 Variables Univariate analysis Multivariate analysis OR (95% CI) P value OR (95% CI) P value Age >61 (years) 1.337 (1.019–4.392) 0.015 0.953 (0.878–1.033) 0.242 Male gender 4.851 (2.014–5.301) 0.001 5.042 (1.633–15.567) 0.005 HR >80 (bpm) 3.945 (1.706–6.953) 0.002 1.088 (1.024–1.157) 0.017 QRS dispersion >20 (ms) 2.911 (0.617–13.738) 0.013 1.020 (1.003–1.037) 0.02 QTc dispersion >53 (ms) 6.101 (1.926–19.323) 0.002 2.378 (1.890–2.561) 0.043 Maximum HsTnT >1105 (ng/L) 3.837 (0.236–8.965) 0.004 2.785 (2.501–3.012) 0.034 Grace Score >112 (points) 7.122 (0.632–12.216) <0.001 2.912 (2.703–3.309) 0.030 Conclusion In NSTEMI, QRS dispersion was positively correlated with SYNTAX score and a cut-off value of 20 ms independently predicted SYNTAX score >33. Regarding in-hospital outcome, QRS dispersion >20 ms was associated with in-hospital higher Killip class, recurrent ischemia, serious ventricular arrhythmias and higher GRACE score

Abstract Purpose Acute coronary syndrome (ACS) is treated with revascularisation procedures such as percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG). Whilst reasonable clinical exclusion criteria exist, age is not one of them and patients of advanced years have been shown to have better outcomes with both treatments than with medical management. We set out to investigate the management and outcomes of patients age seventy five and over, with ACS. Methods A retrospective data analysis of all patients age seventy five and above, prescribed dual antiplatelet therapy (DAPT - aspirin plus clopidogrel or aspirin plus ticagrelor), admitted to our institution over a one year period (April 2015 to April 2016). We analysed electronic records and discharge documents and excluded patients without a diagnosis of ACS. Results 207 patients over 75 years old were treated for ACS; 83.6% (173) were diagnosed with non ST elevation myocardial infarction (NSTEMI), 9.6% (20) diagnosed with ST elevation myocardial infarction (STEMI) and 6.8% (14) diagnosed with unstable angina. 73.4% (152) of patients were managed medically, 14.5% (30) had an angiogram, 11.1% (23) had PCI and 1.0% (2) had CABG. 74.0% (153) of patients were treated with aspirin plus clopidogrel, 26.0% (54) with aspirin plus ticagrelor. Major bleeds were reported in 21 patients (10.1%), 18 of the medically managed patients (8.7%) and 3 in the intervention group (5.5%) (P value 0.30). There were 17 major bleeds in the aspirin and clopidogrel group (11.1%) and 4 in the aspirin and ticagrelor group (7.4%) (P value 0.60). 93 (61.2%) of the medically treated group were alive at one year compared to 47 (85.5%) of the intervention group (P value 0.0008). Conclusion Our data show a clear survival benefit in the intervention group, although comparisons between the groups are challenging given confounding factors, such as co-morbidities and patient preference. However, the high proportion (73.4%) of over 75-years old treated medically warrants further evaluation, given the evidence of benefit for patients in this age group, treated with PCI. We feel there is a need for further research in to the ideas and practice surrounding the management of ACS in the over 75's, and their relation to the available evidence.

Background: Acute myocardial infarction has become a serious financial burden for patients, healthcare system, and society. It is therefore necessary to assess treatment cost of myocardial infarction that had been conducted in many countries in the world and still not fully analysed in Vietnam. Thus, we sought to describe acute ST-elevation myocardial infarction treatment cost and analyse related factors to acute ST-elevation myocardial infarction treatment cost. Methods and Materials: A retrospective cross-sectional study. Patients who was diagnosed by ST-elevation myocardial infarction at Cho Ray Hospital from June 2018 to February 2019, satisfied inclusion and exclusion criteria. Results: We collected 130 patients with acute ST-elevation myocardial infarction with male: female ratio of 3:1, at average age of mean ± Standard deviation (SD) = 62.9 ± 12.6. The length of stay in hospital was mean ± SD = 7.1 ± 3.3 days and the median direct cost of MI was 68,902,500 VND (interquartile range (IQR): 5,737,200 – 104,266,000 VND). The average total cost of acute ST-elevation myocardial infarction in the percutaneous coronary intervention group was more than 16 times as the conservative group. The treatment strategies and hospital complications were major factors that affected treatment cost. Conclusion: The median direct cost of acute ST-elevation myocardial infarction was accounted for 68,902,500 VND. Complications directly affected costs.

Abstract Background Elderly patients form a large and growing part of the patients presenting with non-ST-elevation myocardial infarction (NSTEMI). Choosing the optimal antithrombotic treatment in these elderly patients is more complicated because they frequently have characteristics indicating both a high ischaemic and high bleeding risk. Purpose We describe the treatment of elderly patients (&gt;75 years) admitted with NSTEMI, present the outcomes (major adverse cardiovascular events (MACE) and bleeding) and aim to find predictors for adverse events. Methods The POPular AGE registry is an investigator initiated, prospective, observational, multicentre study of patients aged 75 years or older presenting with NSTEMI. Patients were recruited between August 1st, 2016 and May 7th, 2018 at 21 sites in the Netherlands. The primary composite endpoint of MACE included cardiovascular death, non-fatal myocardial infarction and non-fatal stroke at one-year follow-up. Results A total of 757 patients were enrolled. During hospital stay 76% underwent coronary angiography, 34% percutaneous coronary intervention and 12% coronary artery bypass grafting (CABG). At discharge 78.6% received aspirin (non-users mostly because of the combination of oral anticoagulant and clopidogrel), 49.7% were treated with clopidogrel, 34.2% with ticagrelor and 29.6% were prescribed oral anticoagulation. Eighty-three percent of patients received dual antiplatelet therapy (DAPT) or dual therapy consisting of oral anticoagulation and at least one antiplatelet agent for a duration of 12 months. At one year, the primary outcome of cardiovascular death, myocardial infarction or stroke occurred in 12.3% of patients and major bleeding (BARC 3 or 5) occurred in 4.8% of the patients. The risk of MACE and major bleeding was highest during the first month and stayed high over time for MACE while the risk for major bleeding levelled off. Independent predictors for MACE were age, renal function, medical history of CABG, stroke and diabetes. The only independent predictor for major bleeding was haemoglobin level on admission. Conclusion In this all-comers registry, most elderly patients (≥75 years) with NSTEMI are treated with DAPT and undergoing coronary angiography the same way as younger NSTEMI patients from the SWEDEHEART registry. Aspirin use was lower as was the use of the more potent P2Y12 inhibitors compared to the SWEDEHEART which is very likely due to the concomitant use of oral anticoagulation in 30% of patients. The fact that ischemic risk stays constant over 1 year of follow-up, while the bleeding risk levels off after one month may suggest the need of dual antiplatelet therapy until at least one year after NSTEMI.

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 Whether percutaneous coronary intervention (PCI) is superior to coronary artery bypass grafting (CABG) for the right coronary territory is unknown. The aim of this study was to compare the outcomes and patency in the right coronary territory after CABG or PCI. Methods We studied 2,467 multivessel coronary artery disease patients from January 2001 to December 2011; 1,672 were off-pump CABG patients and 795 were PCI. The graft patency and the presence of major adverse cardiac and cerebrovascular events (MACCEs) including death, myocardial infarction, target vessel revascularization, and stroke were analyzed. Results After propensity score matching, cardiac-related survival was found to be significantly higher in the CABG group than in the PCI group (hazard ratio (HR) for the PCI group: 2.445, p = 0.006). The PCI group showed higher rates of myocardial infarction (HR: 2.571, p = 0.011) and target vessel revascularization (HR: 3.337, p < 0.001). In the right coronary territory, the right internal thoracic artery patency was not different in the PCI group compared with the CABG group (p = 0.248). In CABG group, low right coronary artery graft patency was associated with cardiac-related death (HR: 0.17, p = 0.003) and the occurrence of MACCEs (HR: 0.22, p < 0.001). Conclusion CABG was superior to PCI in patients with multivessel disease. Low graft patency in the right coronary territory was associated with cardiac-related death and the occurrence of MACCEs.
