Gender disparities with the use of percutaneous left ventricular assist device in patients undergoing percutaneous coronary intervention complicated by cardiogenic shock: From pVAD Working Group.

ABSTRACT: BACKGROUND:Hemodynamic support with Impella (Abiomed Inc., Danvers, MA) devices is becoming a more prevalent treatment option for patients with cardiogenic shock (CS) undergoing percutaneous coronary intervention (PCI). There exists only limited published data regarding outcome differences between male and female patients. Therefore, the objective of this paper is to analyze these gender differences between short-term survival and in-hospital outcomes in those undergoing PCI with CS. METHODS:Between January 2011 and July 2016, patients undergoing PCI with simultaneous use of Impella were identified. Only patients presenting with CS were included in the analysis. All-cause in-hospital mortality was the primary outcome. Using SAS 9.4 for propensity score matching, additional secondary outcomes were also compared. RESULTS:The primary outcome was comparable between males and females (39.5% vs. 26.3%, p=0.33) in CS patients. Secondary outcomes were also comparable and included: myocardial infarction, stroke, CS, heart failure, dialysis requirement, bleeding within 72h, blood transfusion, dysrhythmia, composite of all complications, major adverse cardiac events. Survival at 30days was equal in both groups. A reduced mortality in males was noted for pre-PCI initiation of Impella. Additionally, both genders who received pre-PCI Impella support, experienced a significant reduction in inotrope use. CONCLUSIONS:Despite the small number of cohorts, this study did not reveal any significant differences among gender with the use of percutaneous left ventricular assist devices for PCI in patients with acute myocardial infarction complicated by CS. However, initiation of Impella prior to PCI may be associated with improved mortality and morbidity in both genders.

Project description:AimsPercutaneous left ventricular assist devices (pVADs) are used to haemodynamically stabilize patients with cardiogenic shock (CS) caused by acute myocardial infarction (AMI). One out of every two patients has a non-ischaemic cause of CS, and these patients differ profoundly from patients with AMI-related CS. We assessed the usefulness of pVAD support for patients with non-ischaemic CS.Methods and resultsWe analysed 106 patients with CS and Impella® support between 2015 and 2018. CS was non-ischaemic in 36 patients and AMI-related in 70 patients. Compared with the AMI group, those in the non-ischaemic group were significantly younger [median age 62 (50.8, 70.8) years vs. 68 (58.0, 75.5) years, P = 0.007] and had more patients with severely reduced left ventricular function (94% vs. 79%, P = 0.035) and worse glomerular filtration rate [45 (27, 57) mL/min vs. 60 (44, 78) mL/min]. Propensity score matching yielded 31 patients with non-ischaemic CS and 31 patients with AMI-related CS, without a difference in baseline laboratory values or comorbidities. In both groups, pVAD support was performed along with haemodynamic stabilization, reduction of catecholamines and normalization of lactate levels. In 7 days, systolic blood pressure increased from 91 (80, 101) mmHg at baseline to 100 (100, 120) mmHg in the non-ischaemic CS group (P = 0.001) and 89 (80, 100) mmHg at baseline to 112 (100, 128) mmHg in the AMI-related CS group (P = 0.001). Moreover, in 7 days, the need of catecholamines (calculated as vasoactive-inotropic score) decreased from 32.0 (11.1, 47.0) at baseline to 5.3 (0, 16.1) in the non-ischaemic group (P = 0.001) and from 35.2 (18.11, 67.0) to zero (0, 0) in the AMI-related CS group (P = 0.001). Lactate level decreased from 3.8 (2.8, 5.9) mmol/L at baseline to 1.0 (0.8, 2.1) mmol/L (P = 0.001) in the non-ischaemic CS group and from 3.8 (2.6, 6.5) mmol/L to 1.2 (1.0, 2.0) mmol/L in the AMI-related group (P = 0.001). In the non-ischaemic CS group, eight patients (25.8%) were upgraded to veno-arterial extracorporeal membrane oxygenation (VA-ECMO) or long-term mechanical circulatory support. Two of these upgraded patients received heart transplantation. In the AMI group, eight patients (25.8%) were upgraded to VA-ECMO or long-term mechanical circulatory support. Ninety-day survival did not significantly differ between the groups (non-ischaemic CS group 48.4%, AMI-related CS group 45.2%, P = 0.799).ConclusionspVAD support is useful for haemodynamic stabilization of patients with non-ischaemic CS and is valuable as a bridge to patients' recovery or long-term left ventricular support and heart transplantation.

Project description:BackgroundCardiogenic shock (CS) is a state of critical end-organ hypoperfusion due to a primary cardiac disorder. For people with refractory CS despite maximal vasopressors, inotropic support and intra-aortic balloon pump, mortality approaches 100%. Mechanical assist devices provide mechanical circulatory support (MCS) which has the ability to maintain vital organ perfusion, to unload the failing ventricle thus reduce intracardiac filling pressures which reduces pulmonary congestion, myocardial wall stress and myocardial oxygen consumption. This has been hypothesised to allow time for myocardial recovery (bridge to recovery) or allow time to come to a decision as to whether the person is a candidate for a longer-term ventricular assist device (VAD) either as a bridge to heart transplantation or as a destination therapy with a long-term VAD.ObjectivesTo assess whether mechanical assist devices improve survival in people with acute cardiogenic shock.Search methodsWe searched CENTRAL, MEDLINE (Ovid), Embase (Ovid) and Web of Science Core Collection in November 2019. In addition, we searched three trials registers in August 2019. We scanned reference lists and contacted experts in the field to obtain further information. There were no language restrictions.Selection criteriaRandomised controlled trials on people with acute CS comparing mechanical assist devices with best current intensive care management, including intra-aortic balloon pump and inotropic support.Data collection and analysisWe performed data collection and analysis according to the published protocol. Primary outcomes were survival to discharge, 30 days, 1 year and secondary outcomes included, quality of life, major adverse cardiovascular events (30 days/end of follow-up), dialysis-dependent (30 days/end of follow-up), length of hospital stay and length of intensive care unit stay and major adverse events. We used the five GRADE considerations (study limitations, consistency of effect, imprecision, indirectness, and publication bias) to assess the quality of a body of evidence as it relates to the studies which contribute data to the meta-analyses for the prespecified outcomes Summary statistics for the primary endpoints were risk ratios (RR), hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs).Main resultsThe search identified five studies from 4534 original citations reviewed. Two studies included acute CS of all causes randomised to treatment using TandemHeart percutaneous VAD and three studies included people with CS secondary to acute myocardial infarction who were randomised to Impella CP or best medical management. Meta-analysis was performed only to assess the 30-day survival as there were insufficient data to perform any further meta-analyses. The results from the five studies with 162 participants showed mechanical assist devices may have little or no effect on 30-day survival (RR of 1.01 95% CI 0.76 to 1.35) but the evidence is very uncertain. Complications such as sepsis, thromboembolic phenomena, bleeding and major adverse cardiovascular events were not infrequent in both the MAD and control group across the studies, but these could not be pooled due to inconsistencies in adverse event definitions and reporting. We identified four randomised control trials assessing mechanical assist devices in acute CS that are currently ongoing.Authors' conclusionsThere is no evidence from this review of a benefit from MCS in improving survival for people with acute CS. Further use of the technology, risk stratification and optimising the use protocols have been highlighted as potential reasons for lack of benefit and are being addressed in the current ongoing clinical trials.
