Background: In the current era of mechanical circulatory support, limited data are available on prognosis of cardiogenic shock (CS) caused by various diseases. We investigated the characteristics and predictors of in-hospital mortality in Korean patients with CS. Methods: The RESCUE study (Retrospective and Prospective Observational Study to Investigate Clinical Outcomes and Efficacy of Left Ventricular Assist Device for Korean Patients With CS) is a multicenter, retrospective, and prospective registry of patients that presented with CS. Between January 2014 and December 2018, 1247 patients with CS were enrolled from 12 major centers in Korea. The primary outcome was in-hospital mortality. Results: In-hospital mortality rate was 33.6%. The main causes of shock were ischemic heart disease (80.7%), dilated cardiomyopathy (6.1%), myocarditis (3.2%), and nonischemic ventricular arrhythmia (2.5%). Vasopressors were used in 1081 patients (86.7%). The most frequently used vasopressor was dopamine (63.4%) followed by norepinephrine (57.3%). An intraaortic balloon pump was used in 314 patients (25.2%) and extracorporeal membrane oxygenator in 496 patients (39.8%). In multivariable analysis, age ≥70years (odds ratio [OR], 2.73 [95% CI, 1.89–3.94], P <0.001), body mass index <25 kg/m 2 (OR, 1.52 [95% CI, 1.08–2.16], P =0.017), cardiac arrest at presentation (OR, 2.16 [95% CI, 1.44–3.23], P <0.001), vasoactive-inotrope score >80 (OR, 3.55 [95% CI, 2.54–4.95], P <0.001), requiring continuous renal replacement therapy (OR, 4.14 [95% CI, 2.88–5.95], P <0.001), mechanical ventilator (OR, 3.17 [95% CI, 2.16–4.63], P <0.001), intraaortic balloon pump (OR, 1.55 [95% CI, 1.07–2.24], P =0.020), and extracorporeal membrane oxygenator (OR, 1.85 [95% CI, 1.25–2.76], P =0.002) were independent predictors for in-hospital mortality. Conclusions: The in-hospital mortality of patients with CS remains high despite the high utilization of mechanical circulatory support. Age, low body mass index, cardiac arrest at presentation, amount of vasopressor, and advanced organ failure requiring various support devices were poor prognostic factors for in-hospital mortality.

Abstract Background The field of temporary mechanical circulatory support (TMCS) has advanced in last decade justifying that TMCS is increasingly used for treatment of refractory cardiogenic shock (CS). Nevertheless, the efficacy of TMCS (extracorporeal life support (ECLS) and Impella) in CS remains controversial due to the lack of high-quality evidence. The aim of this prospective multicenter observational study simulating a randomized trial was to assess the impact of TMCS on the hospital mortality in patients with CS. Methods This study (ClinicalTrials.gov ID: NCT03528291) was conducted at 3 TMCS centers organized in a cardiac assistance network, one as a level 1 TMCS center (expert center), and 2 as level 2 centers (hub centers). The study was designed and led by the heart team of the expert center with input from the hub centers. All patients admitted to an intensive care unit between July 2017 and May 2020 either directly at the TMCS centers or after transfer from a non-specialized hospital, were screened for TMCS indication provided they were admitted for CS. CS was defined according to the European Society of Cardiology criteria. Were excluded patients younger than 18 years, CS after cardiac surgery, or after cardiac arrest if it was refractory or with a no flow &gt;3 min and/or out-of-hospital cardiac arrest with non-shockable rhythm, or CS in the context of myocardial infarction complications, massive pulmonary embolism, and if TMCS was contraindicated TMCS indication was decided after a multidisciplinary discussion carried out by the “heart team”. Implantation of TMCS resulted from an agreement of the heart team within the first 24 hours after admission mainly based on the initial severity of the CS, or if CS was refractory to the medical treatment. The primary outcome was in-hospital survival. A propensity score-weighted analysis was done for treatment-effect estimation. This method, which weights each patient according to their propensity score, includes all participants in the analysis. Results 246 patients with CS were included in the study: 121 in TMCS group (72% ECLS, 14% Impella, 14% both ECLS and Impella) and 125 in control group. After adjustment by a propensity score, hospital mortality was comparable in the two groups (32% TMCS group vs 27% control group; Odds ratio with TMCS, 1.28; 95% confidence interval, 0.87 to 1.88; p=0.21). Mortality at D180 was also similar in the two group (33% vs 30% respectively; p=0.51). Thromboembolic events were significantly higher in the TCMS group (14% vs 4%; p&lt;0.01) as well as the transfusion rate ((median (IQR); 4.0 (0.0; 9.0) vs 0.0 (0.0; 0.0); p&lt;0.01). Conclusion In our study, the use of TMCS does not seem to improve hospital survival in patients with cardiogenic shock. Thus, TMCS, which are iatrogenic side effects providers, should be reserved for the most severe patient and discussed by a multidisciplinary team.

Background: Peripartum cardiomyopathy (PPCM) is an uncommon form of cardiomyopathy that affects young women at the end of pregnancy or in the first few months following delivery, and is associated with increased morbidity and mortality. In selected patients with cardiogenic shock (CS), mechanical circulatory support (MCS) devices improve outcomes. However, data comparing outcomes of patients with PPCM who develop CS and receive mechanical circulatory support (MCS) vs. those treated medically remains limited. Methods: Using the National Inpatient Database (NIS) we identified patients with PPCM who were treated for CS from 2012 to 2017. Primary outcome was in-hospital mortality. Multivariate analysis models were adjusted for statistically significant differences in baseline characteristics between the groups. Results: A total of 4686 patients were admitted with a diagnosis of PPCM, of these 199 patients developed cardiogenic shock. Only 50 (25.1%) patients received MCS. Patients who received MCS were less likely to have a prior ICD in place (6% vs. 23%, p = 0.008), and were more likely to suffer from end-stage renal disease (6% vs. 0.67%, p = 0.020). There were no other major differences in baseline characteristics among the two groups. The incidence of ICD implant prior to discharge (4% vs. 7.4%, p = 0.243, OR 0.39) and cardiac arrest (16% vs. 7.4%, p = 0.173, OR 2.01) was not significantly different between the groups. There was no significant difference in in-hospital mortality between those who received MCS devices and those treated medically (22% vs 10.1%, p = 0.256, OR 1.73). LOS was longer for the MCS group (23.2% vs. 13.4 mean days, p = 0.001). Conclusions: The use of MCS in PPCM patients who developed cardiogenic shock appears to offer similar survival benefit compared to those treated medically, despite being associated with longer length of stay This finding may be related to the complexity and acuity level of patients receiving MCS compared to those treated medically.

Abstract Background Despite progresses in the reperfusion strategies, the prognosis of patients with cardiogenic shock (CS) remains poor with a high in-hospital mortality rate. Percutaneous mechanical circulatory support systems (pMCS) reducing afterload, preload and myocardial oxygen demand, preventing compensatory tachycardia and increasing mean arterial pressure, lead to improve end-organ perfusion. Since CS progression to a refractory shock state is deleterious, timing of treatment represents a crucial issue in these patients. Purpose The aim of our study was to assess whether a multidisciplinary approach and an early use of pMCS could be safe and effective in improving CS patients' outcome. Methods We examined the outcome in terms of one-month survival of 62 patients (75.8% males, mean age 67.7±12.2 years) admitted between January and December 2018 to our Cardiac Intensive Care Unit (CICU) with cardiogenic shock due to acute coronary syndrome (ACS), acute heart failure (AHF) and other causes in 43.5%, 21.6%, 35.4% of cases respectively. For each patient, a Multidisciplinary Shock Team (CS-Team) including critical care specialists, interventional cardiologists and advanced heart failure specialists, was involved and the early use of pMCS was considered. Results Overall, 52 (83.9%) CS patients underwent pMCS implant, including intra-aortic ballon pump counterpulsation (IABP), Impella system (Impella), venous-arterial extracorporeal membrane oxygenation (VA ECMO) in 67.7%, 46.7%, 11.3% of cases respectively. Median time from the first CS-Team contact to the pMCS implantation was 32.5 (30–60) minutes. Among ACS-CS group, AHF-CS group and CS-due to other causes group, pMCS were implanted in 25 (92.5%), 12 (92.3%) and 15 (68.1%) patients respectively. Lower extremities ischemia, gastrointestinal/intracerebral and life-threatening bleeding and ischemic stroke were observed as pMCS related adverse events in 9.7%, 6.4%, 1.6%, 3.2%, 6.4% of cases respectively. At one month, 56 (90.3%) CS patients were discharged alive while 6 (9.7%) CS patients died during the CICU stay. Conclusion A multidisciplinary approach of CS patients, contemplating an early and extensive use of pMCS, may be effective in the reduction of in-hospital mortality rate with a low and acceptable occurrence of pMCS related adverse events.
