Pulmonary Artery Catheter Usage and Impact on Mortality in Patients With Cardiogenic Shock: Results From a Canadian Single-Centre Registry. Can J Cardiol 2024; 40:664-673. [PMID: 38092192 DOI: 10.1016/j.cjca.2023.12.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 12/06/2023] [Accepted: 12/07/2023] [Indexed: 03/09/2024] Open
Abstract
BACKGROUND Hemodynamic assessment for cardiogenic shock (CS) phenotyping in patients has led to renewed interest in the use of pulmonary artery catheters (PACs). METHODS We included patients admitted with CS from January 2014 to December 2020 and compared clinical outcomes among patients who received PACs and those who did not. The primary outcome was the rate of in-hospital mortality. Secondary outcomes included use of advanced heart failure therapies and coronary intensive care unit (CICU) and hospital lengths of stay. RESULTS A total of 1043 patients were analysed and 47% received PACs. Patients selected for PAC-guided management were younger and had lower left ventricular function. They also had higher use of vasopressor and inotropes, and 15.2% of them were already supported with temporary mechanical circulatory support (MCS). In-hospital mortality was lower in patients who received PACs (29.3% vs 36.2%; P = 0.02), mainly driven by a reduction in mortality among those in Society for Cardiovascular Angiography and Interventions (SCAI) stages D and E CS. Patients who received PACs were more likely to receive temporary MCS with Impella, durable ventricular assist devices (VADs), or orthotopic heart transplantation (OHT) (P < 0.001 for all analyses). CICU and hospital lengths of stay were longer in patients who used PACs. CONCLUSIONS Among patients with CS, the use of PACs was associated with lower in-hospital mortality, especially among those in SCAI stages D and E. Patients who received PACs were also more frequently rescued with temporary MCS or received advanced heart failure therapies, such as durable VADs or OHT.

[PMID: 38012789 PMCID: PMC10683227 DOI: 10.1186/s13054-023-04752-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 11/20/2023] [Indexed: 11/29/2023] Open
Abstract
Recent clinical and research efforts in cardiogenic shock (CS) have largely focussed on the restoration of the low cardiac output state that is the conditio sine qua non of the clinical syndrome. This approach has failed to translate into improved outcomes, and mortality has remained static at 30-50%. There is an unmet need to better delineate the pathobiology of CS to understand the observed heterogeneity of presentation and treatment effect and to identify novel therapeutic targets. Despite data in other critical illness syndromes, specifically sepsis, the role of dysregulated inflammation and immunity is hitherto poorly described in CS. High-dimensional molecular profiling, particularly through leukocyte transcriptomics, may afford opportunity to better characterise subgroups of patients with shared mechanisms of immune dysregulation. In this state-of-the-art review, we outline the rationale for considering molecular subtypes of CS. We describe how high-dimensional molecular technologies can be used to identify these subtypes, and whether they share biological features with sepsis and other critical illness states. Finally, we propose how the identification of molecular subtypes of patients may enrich future clinical trial design and identification of novel therapies for CS.

Arrhythmic events and mortality in patients with cardiogenic shock on inotropic support: results of the DOREMI randomized trial. Can J Cardiol 2022; 39:394-402. [PMID: 36150583 DOI: 10.1016/j.cjca.2022.09.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 09/14/2022] [Accepted: 09/15/2022] [Indexed: 11/02/2022] Open
Abstract
BACKGROUND Inotropic support is widely used in the management of cardiogenic shock (CS). Existing data on the incidence and significance of arrhythmic events in patients with CS on inotropic support is at high risk of bias. METHODS The DObutamine compaREd to MIlrinone (DOREMI) trial randomized patients to receive dobutamine or milrinone in a double-blind fashion. Patients with and without arrhythmic events (defined as arrhythmias requiring intervention or sustained ventricular arrhythmias) were compared to (1) identify factors associated with their occurrence and (2) examine their association with in-hospital mortality and secondary outcomes. RESULTS Ninety-two patients (47.9%) had arrhythmic events, occurring equally with dobutamine and milrinone (P=0.563). The need for vasopressor support at inotrope initiation and a history of atrial fibrillation were positively associated with arrhythmic events whereas predominant right ventricular dysfunction, previous myocardial infarction, and increasing left ventricular ejection fraction were negatively associated with them. Supraventricular arrhythmic events were not associated with mortality (RR 0.97, 95% CI 0.68-1.40, P=0.879) but were positively associated with resuscitated cardiac arrests and hospital length of stay. Ventricular arrhythmic events were positively associated with mortality (RR 1.66, 95% CI 1.13-2.43; P=0.026) and resuscitated cardiac arrests. Arrhythmic events were most often treated with amiodarone (97%) and electrical cardioversion (27%), which were not associated with mortality. CONCLUSIONS Clinically relevant arrhythmic events occur in approximately half of patients with CS treated with dobutamine or milrinone and are associated with adverse clinical outcomes. Five factors may help identify patients most at risk of arrhythmic events.
