Shock subtypes by left ventricular ejection fraction following out-of-hospital cardiac arrest

Post-resuscitation hemodynamic instability following out-of-hospital cardiac arrest (OHCA) may occur from myocardial dysfunction underlying cardiogenic shock and/or inflammation-mediated distributive shock. Di...

AbstractAimsFew studies describe recent changes in the prevalence, management, and outcomes of cardiogenic shock (CS) patients complicating acute myocardial infarction (AMI) in the era of widespread use of invasive strategies. The aim of the present study was to analyse trends observed in CS complicating AMI over the past 10  years, focusing on the timing of CS occurrence (i.e. primary CS, CS on admission vs. secondary CS, CS developed subsequently during hospitalization).Methods and resultsThree nationwide French registries conducted and designed to evaluate AMI management and outcomes in ‘real‐life’ ...

CONCLUSION: Predictors of mortality such as high pulmonary vascular resistance, dialysis dependence, inotrope, and ventilator dependence in patients listed with intra-aortic balloon pump can help us identify those patients that are at high risk of dying prior to a heart transplantation.

Abstract Cardiogenic shock complicating acute myocardial infarction is challenging, and continues to be associated with high rates of in-hospital and long-term mortality. Coronary revascularization is critical for improving prognosis in CS. Thus, a systematic protocol-driven approach to cardiogenic shock, the development of specialized cardiac care centres, technical advances in interventional cardiology enabling treatment of more complex and severe lesions, the availability of recent antithrombotic therapies and the evolution of new haemodynamic support devices are important considerations in current management o...

This was sent by a reader.A previously healthy 53 yo woman was transferred to a receiving hospital in cardiogenic shock.pH was 6.9 and K was normal.Here was the ECG:There is sinus tachycardia.This is " Shark Fin " morphology.Shark Fin has also been called:"Giant R-wave""Triangular QRS-ST-T waveform"Usually shark fin is in one coronary distribution and represents massive ST elevation that is as high as the peak of the R-wave and thereforefuses the R-wave and ST segment.So Shark Fin really is just a dramatic representation of STEMI, and can be in any coronary distribution.It is often confused wi...

Abstract BACKGROUND: French Polynesia is a French overseas collectivity in the South Pacific Ocean, where data on infective endocarditis (IE) are lacking. AIMS: To investigate the epidemiology and outcomes of IE in French Polynesia. METHODS: All hospital records from consecutive patients hospitalized in Taaone Hospital, Tahiti, from 2015 to 2018, with an International Classification of Diseases, 10th revision, separation diagnosis of IE (I330), were reviewed retrospectively. RESULTS: From 190 hospital charts reviewed, 105 patients with a final diagnosis of IE, confirmed according to the mo...

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is sometimes needed for post-cardiotomy cardiogenic shock (PCCS). There is little data regarding outcomes in the Australian context, particularly in a non-cardiac transplant centre. Our aim was to report on 30-day outcomes after patients with PCCS treated with VA-ECMO in an Australian non-cardiac transplant tertiary centre, and to determine risk factors for non-survival in this population.

Background: Thirty-day mortality in ST-elevation myocardial infarction (STEMI) patients is primarily driven by cardiogenic shock (CS). High neutrophil counts and high neutrophil/lymphocyte ratios (NLR) have previously been associated with mortality in STEMI patients; however, there is only sparse knowledge regarding their association with CS. Purpose: We sought to assess the associations between neutrophil count and NLR with the development of CS as well as 30-day mortality in STEMI patients. Methods: Patients admitted with STEMI at two tertiary Heart Centres throughout 1 year were included in the study and stratif...

ConclusionsAcute qRBBB myocardial infarction is a sinister form of acute coronary syndrome which entails high in-hospital mortality and morbidity, necessitating early recognition and prompt institution of reperfusion therapy. Extreme deviation of QRS axis to the right [180-269 degrees] is a significant electrocardiographic predictor of in-hospital mortality.

ConclusionECMO is invaluable in treating patients with medically refractory profound cardiogenic shock and allows for cardiac recovery or planning for permanent heart replacement treatments.
