Project description:Despite an improvement in pharmacological therapies and mechanical reperfusion, the outcome of patients with acute myocardial infarction (AMI) is still suboptimal, especially in patients with cardiogenic shock (CS). The incidence of CS accounts for 3-15% of AMI cases, with mortality rates of 40% to 50%. In contrast to a large number of trials conducted in patients with AMI without CS, there is limited evidence-based scientific knowledge in the CS setting. Therefore, recommendations and actual treatments are often based on registry data. Similarly, knowledge of the available options in terms of temporary mechanical circulatory support (MCS) devices is not equally widespread, leading to an underutilisation or even overutilisation in different regions/countries of these treatment options and nonuniformity in the management of CS. The aim of this article is to provide a critical overview of the available literature on the management of CS as a complication of AMI, summarising the most recent evidence on revascularisation strategies, pharmacological treatments and MCS use.

Project description:BackgroundStudies had previously identified three cardiogenic shock (CS) phenotypes (cardiac-only, cardiorenal, and cardiometabolic). Therefore, we aimed to understand better the hemodynamic profiles of these phenotypes in acute myocardial infarction-CS (AMI-CS) using pulmonary artery catheter (PAC) data to better understand the AMI-CS heterogeneity.MethodsWe analyzed the PAC data of 309 patients with AMI-CS. The patients were classified by SCAI shock stage, congestion profile, and phenotype. In addition, 24 h hemodynamic PAC data were obtained.ResultsWe identified three AMI-CS phenotypes: cardiac-only (43.7%), cardiorenal (32.0%), and cardiometabolic (24.3%). The cardiometabolic phenotype had the highest mortality rate (70.7%), followed by the cardiorenal (52.5%) and cardiac-only (33.3%) phenotypes, with significant differences (p < 0.001). Right atrial pressure (p = 0.001) and pulmonary capillary wedge pressure (p = 0.01) were higher in the cardiometabolic and cardiorenal phenotypes. Cardiac output, index, power, power index, and cardiac power index normalized by right atrial pressure and left-ventricular stroke work index were lower in the cardiorenal and cardiometabolic than in the cardiac-only phenotypes. We found a hazard ratio (HR) of 2.1 for the cardiorenal and 3.3 for cardiometabolic versus the cardiac-only phenotypes (p < 0.001). Also, multi-organ failure, acute kidney injury, and ventricular tachycardia/fibrillation had a significant HR. Multivariate analysis revealed that CS phenotypes retained significance (p < 0.001) when adjusted for the Society for Cardiovascular Angiography & Interventions score (p = 0.011) and ∆congestion (p = 0.028). These scores independently predicted mortality.ConclusionsAccurate patient prognosis and treatment strategies are crucial, and phenotyping in AMI-CS can aid in this effort. PAC profiling can provide valuable prognostic information and help design new trials involving AMI-CS.

Project description:AimsThe aim of this study is to evaluate the contemporary use of a pulmonary artery catheter (PAC) in acute myocardial infarction-cardiogenic shock (AMI-CS).Methods and resultsA retrospective cohort of AMI-CS admissions using the National Inpatient Sample (2000-2014) was identified. Admissions with concomitant cardiac surgery or non-AMI aetiology for cardiogenic shock were excluded. The outcomes of interest were in-hospital mortality, resource utilization, and temporal trends in cohorts with and without PAC use. In the non-PAC cohort, the use and outcomes of right heart catheterization was evaluated. Multivariable regression and propensity matching was used to adjust for confounding. During 2000-2014, 364 001 admissions with AMI-CS were included. PAC was used in 8.1% with a 75% decrease during over the study period (13.9% to 5.4%). Greater proportion of admissions to urban teaching hospitals received PACs (9.5%) compared with urban non-teaching (7.1%) and rural hospitals (5.4%); P < 0.001. Younger age, male sex, white race, higher comorbidity, noncardiac organ failure, use of mechanical circulatory support, and noncardiac support were independent predictors of PAC use. The PAC cohort had higher in-hospital mortality (adjusted odds ratio 1.07 [95% confidence interval 1.04-1.10]), longer length of stay (10.9 ± 10.9 vs. 8.2 ± 9.3 days), higher hospitalization costs ($128 247 ± 138 181 vs. $96 509 ± 116 060), and lesser discharges to home (36.3% vs. 46.4%) (all P < 0.001). In 6200 propensity-matched pairs, in-hospital mortality was comparable between the two cohorts (odds ratio 1.01 [95% confidence interval 0.94-1.08]). Right heart catheterization was used in 12.5% of non-PAC admissions and was a marker of greater severity but did not indicate worse outcomes.ConclusionsIn AMI-CS, there was a 75% decrease in PAC use between 2000 and 2014. Admissions receiving a PAC were a higher risk cohort with worse clinical outcomes.

Project description:Despite advances in percutaneous coronary interventions and their widespread use, mortality in patients presenting with acute myocardial infarction (MI) complicated by cardiogenic shock (CS) has remained very high, and treatment options are limited. Limited evidences exist, supporting many of the routinely used therapies in treating these patients. In the present article, we discuss CS complicating MI in general and an update on the currently available treatment options, including inotropes and vasopressor, coronary revascularization, mechanical circulatory support devices, mechanical complications, and long-term outcomes.

Project description:There are limited data on arrhythmias in acute myocardial infarction with cardiogenic shock (AMI-CS). Using a 17-year AMI-CS population from the National Inpatient Sample, we identified common arrhythmias - atrial fibrillation (AF), atrial flutter, supraventricular tachycardia, ventricular tachycardia, ventricular fibrillation, and atrioventricular blocks (AVB). Admissions with concomitant cardiac surgery were excluded. Outcomes of interest included temporal trends, predictors, in-hospital mortality, and resource utilization in cohorts with and without arrhythmias. Of the 420,319 admissions with AMI-CS during 2000 to 2016, arrhythmias were noted in 213,718 (51%). AF (45%), ventricular tachycardia (35%) and ventricular fibrillation (30%) were the most common arrhythmias. Compared with those without, the cohort w`ith arrhythmias was more often male, of white race, with ST-segment elevation AMI-CS presentation, and had higher rates of cardiac arrest and acute organ failure (all p <0.001). Temporal trends of prevalence revealed a stable trend of atrial and ventricular arrhythmias and declining trend in AVB. The cohort with arrhythmias had higher unadjusted (42% vs 41%; odds ratio [OR] 1.03 [95% confidence interval 1.02 to 1.05]; p <0.001), but not adjusted (OR 1.01 [95% CI 0.99 to 1.03]; p = 0.22) in-hospital mortality compared with those without. The cohort with arrhythmias had longer hospital stay (9 ± 10 vs 7 ± 9 days; p <0.001) and higher hospitalization costs ($124,000 ± 146,000 vs $91,000 ± 115,000; p <0.001). In the cohort with arrhythmias, older age, female sex, non-white race, higher co-morbidity, presence of acute organ failure, and cardiac arrest, predicted higher in-hospital mortality. In conclusion, cardiac arrhythmias in AMI-CS are a marker of higher illness severity and are associated with greater resource utilization.

Project description:BackgroundTo assess the recovery and prognostic values of myocardial strain using cardiac magnetic resonance (CMR)- feature tracking (FT) in acute anterior and non-anterior wall myocardial infarction.Methods103 reperfused patients after STEMI who underwent CMR at about 4 days (baseline) and 4 months (follow-up) were included, including 48 and 55 patients with anterior wall myocardial infarction (AWMI) and non-anterior wall myocardial infarction(NAWMI). CMR-FT analysis was performed using cine images to measure LV global radial, circumferential, and longitudinal peak strains (GRS, GCS, and GLS, respectively). Infarct size (IS) and microvascular obstruction (MVO) were estimated by late-gadolinium enhancement imaging. The primary clinical endpoint was the occurrence of major adverse cardiac events (MACE) after infarction.ResultsPatients with AWMI had higher IS, higher MVO, lower ejection fraction, and more significantly impaired CMR-FT strain values than patients with NAWMI (all p<0.05). Global strain significantly improved at 4 months (all p<0.01), especial in NAWMI. GLS was an independent predictor (odds ratio = 2.08, 95% confidence interval = 1.032-4.227, p = 0.04] even after adjustment for IS and MVO. The optimal cutoff of GLS was -7.9%, with sensitivity and specificity were 73.3% and 75.0%, respectively. In receiver operating characteristic analysis, IS remained the strongest predictor (area under the curve [AUC] = 0.83, p<0.01), followed by MVO (AUC = 0.81, p<0.01) and GLS (AUC = 0.78, p<0.01).ConclusionCMR-FT-derived global myocardial strains significantly improved over time, especial in NAWMI. GLS measurement independently predicted the occurrence of medium-term MACE.

Project description:Background:Cardiogenic shock is associated with high mortality, despite new strategies for reperfusion therapy. Short-term circulatory support devices may provide adequate support for appropriate myocardial and organ perfusion. Objectives:This review is aimed at evaluating the impact on survival when using venoarterial extracorporeal membrane oxygenation (V-A ECMO) in patients with cardiogenic shock due to acute myocardial infarction (AMI). Methods:We performed a systematic review that included studies using V-A ECMO in patients with cardiogenic shock. Time on ECMO, side effects, and the number of deceased patients, transplanted or upgraded to durable assist devices were analysed. Literature search was done using PubMed/MEDLINE (inception (1969) to January 10, 2019), ProQuest (inception (January 14, 1988) to January 10, 2019), and clinicaltrials.gov (inception (September 12, 2005) to January 10, 2019), by 2 authors. This protocol is registered with PROSPERO (no. CRD42019123982). Results:We included 9 studies with a total of 1,998 adult patients receiving V-A ECMO for AMI-induced cardiogenic shock. Survival rate varied from 30.0% to 79.2% at discharge and from 23.2% to 36.1% at 12 months. Time on ECMO varied between 1.96 and 6.0 days. Reported serious adverse events were gastrointestinal bleeding (3.6%) and peripheral complications (8.5%). Conclusion:The use of V-A ECMO among patients with AMI-induced cardiogenic shock may provide survival benefits. However, V-A ECMO treatment effects are inconclusive because of limitations in cohort design and reporting.

Project description:ObjectiveTo evaluate the prevalence and impact of respiratory infections in cardiogenic shock complicating acute myocardial infarction (AMI-CS).MethodsUsing the National Inpatient Sample (2000-2017), this study identified adult (≥18 years) admitted with AMI-CS complicated by respiratory infections. Outcomes of interest included in-hospital mortality of AMI-CS admissions with and without respiratory infections, hospitalization costs, hospital length of stay, and discharge disposition. Temporal trends of prevalence, in-hospital mortality and cardiac procedures were evaluated.ResultsAmong 557,974 AMI-CS admissions, concomitant respiratory infections were identified in 84,684 (15.2%). Temporal trends revealed a relatively stable trend in prevalence of respiratory infections over the 18-year period. Admissions with respiratory infections were on average older, less likely to be female, with greater comorbidity, had significantly higher rates of NSTEMI presentation, and acute non-cardiac organ failure compared to those without respiratory infections (all p < 0.001). These admissions received lower rates of coronary angiography (66.8% vs 69.4%, p < 0.001) and percutaneous coronary interventions (44.8% vs 49.5%, p < 0.001), with higher rates of mechanical circulatory support, pulmonary artery catheterization, and invasive mechanical ventilation compared to AMI-CS admissions without respiratory infections (all p < 0.001). The in-hospital mortality was lower among AMI-CS admissions with respiratory infections (31.6% vs 38.4%, adjusted OR 0.58 [95% CI 0.57-0.59], p < 0.001). Admissions with respiratory infections had longer lengths of hospital stay (127-20 vs 63-11 days, p < 0.001), higher hospitalization costs and less frequent discharges to home (27.1% vs 44.7%, p < 0.001).ConclusionsRespiratory infections in AMI-CS admissions were associated with higher resource utilization but lower in-hospital mortality.

Project description:OBJECTIVES:To characterize patient profile and hemodynamic profile of those undergoing intra-aortic balloon pump (IABP) for cardiogenic shock and define predictors of hemodynamic failure of IABP support. BACKGROUND:Clinical characteristics of IABP support in cardiogenic shock not related to acute myocardial infarction (AMI) remain poorly characterized. METHODS:We retrospectively studied a cohort of 74 patients from 2010 to 2015 who underwent IABP insertion for cardiogenic shock complicating acute decompensated heart failure not due to AMI. RESULTS:In the overall cohort, which consisted primarily of patients with chronic systolic heart failure (89%), IABP significantly augmented cardiac index and lowered systemic vascular resistance (P<.05). Despite this improvement, 28% of these patients died (24%) or require urgent escalation in mechanical circulatory support (MCS) (4%). Multivariable regression revealed that baseline left ventricular cardiac power index (LVCPI), a measure of LV power output derived from cardiac index and mean arterial pressure (P=.01), and history of ischemic cardiomyopathy (P=.003) were significantly associated with the composite adverse-event endpoint of death or urgent MCS escalation. An IABP Failure risk score using baseline LVCPI <0.28 W/m2 and ischemic history predicted 28-day adverse events with excellent discrimination. CONCLUSION:Despite hemodynamic improvements with IABP support, patients with non-AMI cardiogenic shock still suffer poor outcomes. Patients with ischemic cardiomyopathy and low LVPCI fared significantly worse. These patients may warrant closer observation or earlier consideration of more advanced hemodynamic support.
