ObjectiveWe investigated the benefit of Impella, a modern percutaneous mechanical support (pMCS) device, versus former standard intra-aortic balloon pump (IABP) in acute myocardial infarction complicated by cardiogenic shock (AMICS).MethodsThis single-centre, retrospective study included patients with AMICS receiving pMCS with either Impella or IABP. Disease severity at baseline was assessed with the IABP-SHOCK II score. The primary outcome was all-cause mortality at 30 days. Secondary outcomes were parameters of shock severity at the early postimplantation phase. Adjusted Cox proportional hazards models identified independent predictors of the primary outcome.ResultsOf 116 included patients, 62 (53%) received Impella and 54 (47%) IABP. Despite similar baseline mortality risk (IABP-SHOCK II high-risk score of 18 % vs 20 %; p = 0.76), Impella significantly reduced the inotropic score (p < 0.001), lactate levels (p < 0.001) and SAPS II (p =0.02) and improved left ventricular ejection fraction (p = 0.01). All-cause mortality at 30 days was similar with Impella and IABP (52 % and 67 %, respectively; p = 0.13), but bleeding complications were more frequent in the Impella group (3 vs 4 units of transfused erythrocytes concentrates due to bleeding complications, p = 0.03). Previous cardiopulmonary resuscitation (HR 3.22, 95% CI 1.76 to 5.89; p < 0.01) and an estimated intermediate (HR 2.77, 95% CI 1.42 to 5.40; p < 0.01) and high (HR 4.32 95% CI 2.03 to 9.24; p = 0.01) IABP-SHOCK II score were independent predictors of all-cause mortality.ConclusionsIn patients with AMICS, haemodynamic support with the Impella device had no significant effect on 30-day mortality as compared with IABP. In these patients, large randomised trials are warranted to ascertain the effect of Impella on the outcome.

Abstract Introduction Early identification of high-risk patients is the cornerstone of managing patients with acute myocardial infarction (AMI). Age Shock index (ASI; age multiplied by the ratio of heart rate/systolic blood pressure) has been reported to be similar to Global Registry of Acute Coronary Events (GRACE) risk score for predicting mortality in patients with AMI. However, prognostic impacts of prehospital ASI (pre-ASI) in patients with AMI remain unknown. Methods We analyzed of 2578 AMI patients who underwent emergency primary percutaneous coronary intervention (PCI) from January 2013 to March 2018, using data from Mie ACS Registry, a prospective and multicenter registry in Japan. Pre-ASI was recorded by emergency medical services at the first contact with the patient before admission, and in-hospital ASI (in-ASI) was recorded prior to PCI at admission. The primary end point was defined as all-cause death. Results Median follow-up duration was 753 days (497–838 days). All-cause death was observed in 230 (8.9%) patients. The ROC-AUC (Receiver operating characteristic-area under the curve) of pre-ASI for all- cause death was 0.76 (p&lt;0.001), which was similar to that of in-ASI (0.78, p&lt;0.001) (p=0.25 for pre-ASI versus in-ASI). The cut-off value for pre-ASI and in-ASI was for the prediction of all-cause death was both 45 with a sensitivity of 0.66 and a specificity of 0.78, with a sensitivity of 0.68 and a specificity of 0.76 respectively. According to the Kaplan-Meier survival analysis by combination of pre-ASI≥45 and in-ASI≥45, the patients with pre-ASI≥45 and in-ASI≥45 showed significantly higher all-cause mortality compared to the patients with pre-ASI≥45 and in-ASI&lt;45, the patients with pre-ASI&lt;45 and in-ASI≥45, and the patients with pre-ASI&lt;45 and in-ASI&lt;45 (p&lt;0.001) (Figure). The addition of pre-ASI≥45 to in-ASI≥45 (global chi-squared score: 205) resulted in a significantly increased global chi-squared score, suggesting the incremental prognostic value of pre-ASI (267; p&lt;0.001). Multivariate cox proportional hazard regression analysis for all-cause mortality demonstrated pre-ASI≥45 was a significant independent predictor (HR: 4.86; 95% CI: 3.36 to 7.02, p&lt;0.001). It was strongest predictor compared to left ventricular ejection fraction&lt;40% (HR: 2.45; 95% CI 1.67 to 3.58, p&lt;0.001), hemodialysis (HR: 3.45; 95% CI 1.66 to 7.17, p=0.001), door to balloon time&gt;90 minutes (HR: 1.66; 95% CI 1.18 to 2.34, p=0.004). Conclusions High pre-ASI predict increase mortality and assessment of both high pre-ASI and high in-ASI enhance risk stratification in patients with AMI. Early recognizing high pre-ASI may help us make better strategies and improve prognosis for high-risk AMI patients. Figure 1 Funding Acknowledgement Type of funding source: None

Abstract Background Aortic valve stenosis (AS) is associated with the presence and severity of coronary artery disease independently of clinical risk factors, which leads to increased cardiovascular mortality. However, the prevalence of AS and its prognostic value among patients with acute myocardial infarction (AMI) remain unknown. Purpose The purpose of this study was to investigate the prevalence and prognostic impact of AS in AMI patients. Methods We studied 2,803 AMI patients using data from Mie ACS registry, a prospective and multicenter registry. Patients were divided into subgroups according to the presence and severity of AS based on maximal aortic flow rate by Doppler echocardiography before hospital discharge: non-AS <2.0 m/s, 2.0 m/s≤mild AS <3.0 m/s, 3.0 m/s≤moderate AS <4.0m/s and severe AS≥4.0 m/s. The primary outcome was defined as 2-year all-cause mortality. Results AS was detected in 79 patients (2.8%) including 49 mild AS, 23 moderate AS and 6 severe AS. AS patients were significantly older (79.9±9.8 versus 68.3±12.6 years), and higher killip classification than non-AS patients (P<0.01, respectively). However, left ventricular ejection fraction, and prevalence of primary PCI was similar between the 2 groups. During the follow-up periods (median 725 days), 333 (11.9%) patients experienced all-cause death. AS patients demonstrated the higher all-cause mortality rate compared to that of non-AS patients during follow up (47.3% versus 11.3%, P<0.0001, chi square). Kaplan-Meier curves showed that the probability of all-cause mortality was significantly higher among AS patients than non-AS patients, and was highest among moderate and severe AS (See figure A and B). Cox regression analyses for all-cause mortality demonstrated that the severity of AS was the strongest and independent poor prognostic factor (HR 1.71, 95% CI 1.30–2.24, P<0.001, See table). Cox hazard regression analysis Hazard ratio 95% Confidential interval P-value Severity of aortic valve stenosis 1.71 1.30–2.24 <0.001 Killip classification 1.63 1.46–1.82 <0.001 Age 1.07 1.06–1.09 <0.001 Serum creatinine level 1.05 1.03–1.08 <0.001 Max CPK level 1.00 1.00–1.01 <0.001 Left ventricular ejection fraction 0.96 0.95–0.97 <0.001 Primary percutaneous coronary intervention 0.67 0.47–0.96 0.03 CPK suggests creatinine phosphokinase. All cause mortality Conclusions The presence of AS of any severity contributes to worsening of patients' prognosis following AMI independently of other known risk factors.

Abstract Purpose: A comprehensive evaluation of the benefits of mineralocorticoid receptor antagonists (MRA) in acute myocardial infarction (AMI) patients is lacking. We aimed to summarize the evidence on the efficacy and safety of MRA in post-AMI patients.Methods: Articles were identified through PubMed, Embase, Cochrane Library, Ovid (Medline1946-2021) and ClinicalTrials.gov databases from their inception to Dec 31, 2020. Results: MRA reduced the risk of all-cause mortality by 16% (relative ratio(RR) 0.84, 95% confidence interval(CI) (0.76,0.94), P=.002), new or worsening heart failure (HF) 14% (RR 0.86, 95%CI (0.78,0.96), P=.007), death from HF by 22% (RR 0.78, 95%CI (0.62,0.99), P=.04), and cardiovascular death by 16% (RR 0.84, 95%CI (0.74,0.94), P=.003) in post-AMI patients. Meanwhile, all-cause mortality was reduced by 38% (RR 0.62, 95%CI (0.42,0.90), P=.01), 30% (RR 0.70, 95%CI (0.49,1.00), P=.05), and 29% (RR 0.71, 95%CI (0.59,0.86), P=.0004) in ST-elevation myocardial infarction (STEMI) patients and those who initiated MRA treatment within 3 days and (3,7) days, respectively. Post-AMI patients without left ventricular systolic dysfunction (LVSD) treated with MRA improved left ventricular ejection fraction (mean difference[MD] 2.74, 95%CI (2.49,2.99), P<.00001) and reduced left ventricular end-systolic and end-diastolic volume indices (MD -6.23, 95%CI (-10.93,-1.52), P=.009; MD -3.13, 95%CI (-5.79,-0.47), P=.02). The corresponding RR were 1.73 (95%CI (1.44,2.08), P<.00001) for considered common side effects (hyperkalemia and gynecomastia).Conclusion: Our findings suggest that all-cause mortality is lower in STEMI patients and in patients initiating MRA within 7 days, and that post-AMI patients without LVSD have improved left ventricular remodeling and cardiac function.

The conditions of the pandemic caused by the novel coronavirus infection (COVID-19) are associated with overloading intensive care units, conversion of hospitals, and changes in routing of patients with acute cardiovascular pathology. At the same time, medical practice is still challenged to provide medical care to patients with acute coronary syndrome (ACS). Patients with COVID-19 and acute myocardial infarction (AMI) are at a higher risk of death while the incidence of this combination of diseases will be growing. This article describes a case of diagnosis and treatment of COVID-19 in a 69-year-old patient who was urgently hospitalized with cardiogenic shock associated with ACS, electrocardiographic signs of complete left bundle branch block, and left ventricular ejection fraction of 19 %. Coronary angiography with stenting was successfully performed in the conditions of extracorporeal membrane oxygenation. The patient received long-term intensive therapy in the intensive care unit followed by symptomatic treatment in the cardiac surgery unit. The patient’s condition gradually improved and he was discharged from the hospital on the 56th day. The strategy of intensive care and active follow-up helped saving life of the patient with COVID-19 and AMI.

Abstract Pivotal trials of beta-blockers (BB) and angiotensin converting enzyme inhibitors/angiotensin receptor blockers (ACEI/ARB) in acute myocardial infarction (AMI) were largely conducted prior to the widespread adoption of early revascularization. A total of 15,073 patients with AMI who underwent inhospital coronary revascularization from January 2007 to December 2013 were analyzed. At 12 months, BB was significantly associated with a lower incidence of major adverse cardiovascular events (MACE, adjusted HR 0.80, 95% CI 0.70–0.93) and all-cause mortality (adjusted HR 0.69, 95% CI 0.55–0.88), while ACEI/ARB was significantly associated with lower all-cause mortality (adjusted HR 0.80, 95% CI 0.66–0.98) and heart failure (HF) hospitalization (adjusted HR 0.80, 95% CI 0.68–0.95). Combined BB and ACEI/ARB use was associated with the lowest incidence of MACE (adjusted HR 0.70, 95% CI 0.57–0.86), all-cause mortality (adjusted HR 0.55, 95% CI 0.40–0.77) and HF hospitalization (adjusted HR 0.64, 95% CI 0.48–0.86). This were consistent for left ventricular ejection fraction < 50% or ≥ 50%. In conclusion, in AMI managed with revascularization, both BB and ACEI/ARB were associated with a lower incidence of 12-month all-cause mortality. Combined BB and ACEI/ARB was associated with the lowest incidence of all-cause mortality and HF hospitalization.

Abstract Funding Acknowledgements None Background/Introduction Left ventricular (LV) thrombus is a widely recognized complication of acute myocardial infarction (AMI).  Limited data are available from South East Asian patients with this post-infarction complication nor on whether patients with non-ST segment elevation myocardial infarction (NSTEMI) or STEMI with associated LV thrombosis exhibit differing clinical characteristics and/or outcomes. Left Ventricular Ejection Fraction (LVEF) ≤ 40% is a recognized predictor of LV thrombus formation, but there is limited data on LV thrombus patients with EF &gt; 40% or in NSTEMI patients. Purpose This study aims to investigate and compare the clinical characteristics, treatment and outcomes of post-AMI patients with LV thrombus formation, with a particular emphasis on those with EF ≤ 40% and in NSTEMI patients.  Methods Among 5829 consecutive echocardiogram results containing the keyword "thrombus" from August 2006 to September 2017, we identified 289 post-AMI patients with acute LV thrombus formation. Demographics, treatment and outcome measures were analysed. Results Cardiovascular risk factors such as dyslipidaemia (54.0%) and hypertension (50.5%) were commonly present in post-AMI patients with LV thrombus. Mean LVEF was 33.0 ± 10.4%. The majority (68.0%) of patients received triple therapy and 59.5% achieved thrombus resolution. NSTEMI patients had greater number of co-morbidities including heart failure (p &lt; 0.01), documented history of  ischaemic heart disease preceding the AMI leading to thrombus formation (p &lt; 0.01) and lower LVEF (28.3 ± 9.3% vs. 34.8 ± 10.3% , p &lt; 0.01) compared with STEMI cases. On multivariate analysis, having a lower EF was a significant independent predictor of stroke (HR 0.96, 95% CI 0.93-1.00, p = 0.03) and all-cause mortality (HR 0.95, 95% CI 0.92-0.99, p &lt; 0.01). The categories of STEMI and NSTEMI did not predict thrombus resolution, stroke events or all-cause mortality after adjustment. Conclusion(s)   Post-AMI LV thrombus patients with NSTEMI and STEMI differed in terms of their co-morbidities in their demographics and co-morbidities but it was a lower EF that was associated with an increased risk of stroke and all-cause mortality. Further studies on this topic are required.

Background. A comprehensive evaluation of the benefits of mineralocorticoid receptor antagonists (MRA) in acute myocardial infarction (AMI) patients is lacking. Objective. To summarize the evidence on the efficacy and safety of MRA in patients admitted for AMI. Methods. Articles were identified through PubMed, Embase, Cochrane Library, Ovid (Medline1946-2021), and ClinicalTrials.gov databases from their inception to December 31, 2020. Results. 15 articles with a total of 11,861 patients were included. MRA reduced the risk of all-cause mortality by 16% (relative ratio (RR): 0.84; 95% confidence interval (CI) (0.76, 0.94); P = 0.002 ) and the incidence of cardiovascular adverse events by 12% (RR: 0.88, 95% CI (0.83, 0.93), P < 0.00001 ) in post-AMI patients, and further analysis demonstrated that early administration of MRA within 7 days after AMI resulted in a greater reduction in all-cause mortality (RR: 0.72, 95% CI (0.61, 0.85), P < 0.0001 ). Subgroup analyses showed that post-STEMI patients without left ventricular systolic dysfunction (LVSD) treated with MRA had a 36% reduction in all-cause mortality (RR: 0.64, 95% CI (0.46, 0.89), P = 0.007 ) and a 22% reduction in cardiovascular adverse events (RR: 0.78, 95% CI (0.67, 0.91), P = 0.002 ). Meanwhile, post-STEMI patients without LVSD treated with MRA get significant improvements in left ventricular ejection fraction (mean difference (MD): 2.69, 95% CI (2.44, 2.93), P < 0.00001 ), left ventricular end-systolic index (MD: -4.52 ml/m2, 95% CI (-8.21, -0.83), P = 0.02 ), and left ventricular end-diastolic diameter (MD: -0.11 cm, 95% CI (-0.22, 0.00), P = 0.05 ). The corresponding RR were 1.72 (95% CI (1.43, 2.07), P < 0.00001 ) for considered common adverse events (hyperkalemia, gynecomastia, and renal dysfunction). Conclusions. Our findings suggest that MRA treatment reduces all-cause mortality and cardiovascular adverse events in post-AMI patients, which is more significant in patients after STEMI without LVSD. In addition, MRA treatment may exert beneficial effects on the reversal of cardiac remodeling in patients after STEMI without LVSD.
