RESUMO
BACKGROUND: Previous studies have suggested that there is wide variability in cardiac intensive care unit (CICU) length of stay (LOS); however, these studies are limited by the absence of detailed risk assessment at the time of admission. Thus, we evaluated inter-hospital differences in CICU LOS, and the association between LOS and in-hospital mortality. METHODS: Using data from the Critical Care Cardiology Trials Network (CCCTN) registry, we included 22,862 admissions between 2017 and 2022 from 35 primarily tertiary and quaternary CICUs that captured consecutive admissions in annual 2-month snapshots. The primary analysis compared inter-hospital differences in CICU LOS, as well as the association between CICU LOS and all-cause in-hospital mortality using a Fine and Gray competing risk model. RESULTS: The overall median CICU LOS was 2.2 (1.1-4.8) days, and the median hospital LOS was 5.9 (2.8-12.3) days. Admissions in the longest tertile of LOS tended to be younger with higher rates of pre-existing comorbidities, and had higher Sequential Organ Failure Assessment (SOFA) scores, as well as higher rates of mechanical ventilation, intravenous vasopressor use, mechanical circulatory support, and renal replacement therapy. Unadjusted all-cause in-hospital mortality was 9.3%, 6.7%, and 13.4% in the lowest, intermediate, and highest CICU LOS tertiles. In a competing risk analysis, individual patient CICU LOS was correlated (r2 = 0.31) with a higher risk of 30-day in-hospital mortality. The relationship remained significant in admissions with heart failure, ST-elevation myocardial infarction and non-ST segment elevation myocardial infarction. CONCLUSIONS: In a large registry of academic CICUs, we observed significant variation in CICU LOS and report that LOS is independently associated with all-cause in-hospital mortality. These findings could potentially be used to improve CICU resource utilization planning and refine risk prognostication in critically ill cardiovascular patients.

BACKGROUND: There are limited data on how patients with cardiogenic shock (CS) die. METHODS: The Critical Care Cardiology Trials Network is a research network of cardiac intensive care units coordinated by the Thrombolysis In Myocardial Infarction (TIMI) Study Group (Boston, MA). Using standardized definitions, site investigators classified direct modes of in-hospital death for CS admissions (October 2021 to September 2022). Mutually exclusive categories included 4 modes of cardiovascular death and 4 modes of noncardiovascular death. Subgroups defined by CS type, preceding cardiac arrest (CA), use of temporary mechanical circulatory support (tMCS), and transition to comfort measures were evaluated. RESULTS: Among 1068 CS cases, 337 (31.6%) died during the index hospitalization. Overall, the mode of death was cardiovascular in 82.2%. Persistent CS was the dominant specific mode of death (66.5%), followed by arrhythmia (12.8%), anoxic brain injury (6.2%), and respiratory failure (4.5%). Patients with preceding CA were more likely to die from anoxic brain injury (17.1% vs 0.9%; P < .001) or arrhythmia (21.6% vs 8.4%; P < .001). Patients managed with tMCS were more likely to die from persistent shock (P < .01), both cardiogenic (73.5% vs 62.0%) and noncardiogenic (6.1% vs 2.9%). CONCLUSIONS: Most deaths in CS are related to direct cardiovascular causes, particularly persistent CS. However, there is important heterogeneity across subgroups defined by preceding CA and the use of tMCS.

BACKGROUND: The application of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in contemporary management of cardiogenic shock (CS) has dramatically increased. Despite increased utilization, few predictive models exist to estimate patient survival based on pre-ECMO characteristics. Furthermore, the prognostic implications of pre-ECMO cardiac arrest are not well defined. METHODS: Utilizing an institutional VA-ECMO database, all consecutive patients undergoing VA-ECMO for the management of CS from January 1, 2014, to July 1, 2019, were identified. Survival to hospital discharge was analyzed based on cannulation indication in patients with and without pre-ECMO cardiac arrest. Patients who received extracorporeal cardiopulmonary resuscitation (eCPR) were analyzed separately. RESULTS: Of the 214 patients identified, 110 did not suffer a cardiac arrest prior to cannulation (cohort 1), 57 patients had a cardiac arrest with sustained ROSC (cohort 2), and 47 were cannulated as a component of eCPR (cohort 3). Despite sustained ROSC (cohort 2), the presence of pre-ECMO cardiac arrest was associated with a significant reduction in survival to hospital discharge (22.8% vs. 55.5% in cohort 1; p < 0.001). Comparatively, survival to discharge was similar in patients undergoing eCPR (22.8% vs. 17.0%; p = 0.464). Finally, patients with a cardiac arrest were significantly more likely to have a neurological etiology death with VA-ECMO than patients supported prior to hemodynamic collapse (18.3% vs. 2.7%; p < 0.001). This result is seen in those with sustained ROSC (21.1% vs. 2.7%; p < 0.001) and those with eCPR (14.9% vs. 2.7%; p = 0.004). CONCLUSION: In our cohort, pre-ECMO cardiac arrest carries a negative prognostic value across all indications and is associated with an increased prevalence of neurological-etiology death. This finding is true in patients with sustained ROSC as well as those resuscitated with eCPR. Cardiac arrest can inform survival probability with VA-ECMO as early implementation of VA-ECMO may mitigate adverse outcomes in patients at the highest risk of hemodynamic collapse.

Advancements in cardiac arrest and post-cardiac arrest care have led to improved survival to hospital discharge. While survival to hospital discharge is an important clinical outcome, neurologic recovery is also a priority. With the advancement of targeted temperature management (TTM), the American Heart Association guidelines for post-cardiac arrest care recommend TTM in patients who remain comatose after return of spontaneous circulation (ROSC). Recently, the TTM2 randomized controlled trial found no significant difference in neurologic function and mortality at 6-months between traditional hypothermia to 33°C versus 37.5°C. While TTM has been evaluated for decades, current literature suggests that the use of TTM to 33° when compared to a protocol of targeted normothermia does not result in improved outcomes. Instead, perhaps active avoidance of fever may be most beneficial. Extracorporeal cardiopulmonary resuscitation and membrane oxygenation can provide a means of both hemodynamic support and TTM after ROSC. This review aims to describe the pathophysiology, physiologic aspects, clinical trial evidence, changes in post-cardiac arrest care, potential risks, as well as controversies of TTM.

OBJECTIVES: We sought to derive and validate a model to predict inpatient mortality after veno-arterial extracorporeal life support (VA-ECLS) based on readily available, precannulation clinical data. BACKGROUND: Refractory cardiogenic shock supported by VA-ECLS is associated with high morbidity and mortality. METHODS: VA-ECLS cases at our institution from January 2014 through July 2019 were retrospectively reviewed. Exclusion criteria were cannulation: (1) at another institution; (2) for primary surgical indication; or (3) for extracorporeal cardiopulmonary resuscitation. Multivariable logistic regression compared those with and without inpatient mortality. Multiple imputation was performed and optimism-adjusted area under the curve (oAUC) values were computed. RESULTS: VA-ECLS cases from August 2019 through November 2020 were identified as a validation cohort. In the derivation cohort (n = 135), the final model included Lactate (mmol/L), hemoglobin (g/dl; Anemia), Coma (Glasgow Coma Scale [GCS] < 8) and resusciTATEd cardiac arrest (LACTATE score; oAUC = 0.760). In the validation cohort (n = 30, LACTATE showed similar predictability [AUC = 0.710]). A simplified (LACT-8) score was derived by dichotomizing lactate (>8) and hemoglobin (<8) and summing together the number of components for each patient. LACT-8 performed similarly (derivation, oAUC = 0.724; validation, AUC = 0.725). In the derivation cohort, both scores outperformed SAVE (oAUC = 0.568) and SOFA (oAUC = 0.699) scores. A LACT-8 ≥ 3 had a specificity for mortality of 97.9% and 92.9%, in the derivation and validation cohorts, respectively. CONCLUSIONS: The LACT-8 score can predict inpatient mortality prior to before cannulation for VA-ECLS. LACT-8 can be implemented utilizing clinical data without the need for an online calculator.

OBJECTIVE. Atrial fibrillation (AF) is a major risk factor for stroke. The CHA2DS2-VASc score is used to risk stratify patients, and the score includes known coronary artery disease (CAD) as a variable. The aim of this study was to assess if the presence of incidental coronary artery calcification (CAC), without known CAD, is associated with stroke independent of CHA2DS2-VASc variables. MATERIALS AND METHODS. A retrospective review of health records was performed for patients who had AF, a chest CT scan performed within 1 year, and a subsequent visit for stroke. Patients with CAD and other vascular disease, a mechanical valve, or who were older than 74 years old were excluded. Included patients were one-to-one matched by age and CHA2DS2-VASc risk factors to patients who had had similar follow-up but who did not have a stroke. Nongated CT images were reviewed for CAC. Univariate and Cox regression analyses were performed. RESULTS. A total of 203 patients met the study criteria, and 203 matched patients without stroke were identified. Median age was 61 years old with stroke and 62 years old without stroke (p = 0.99). In both groups, 82 (39.0%) were women and the median CHA2DS2-VASc was 2 (interquartile range, 1-2). Anticoagulation medication was prescribed to 46 (22.7%) patients in the group who had had a stroke and 52 (25.6%) in the group without stroke (p = 0.49). On Cox regression analysis, CAC was associated with stroke (hazard ratio [HR], 1.47; 95% CI, 1.10-1.97; p < 0.01) and mortality (adjusted HR, 1.41; 95% CI, 1.02-1.95; p = 0.04). CONCLUSION. Patients with AF and incidental CAC depicted on chest CT have an increased risk of stroke and mortality beyond established risk factors.

INTRODUCTION: Malignancy is a common cause of morbidity and mortality in the United States and around the world and the second leading cause of death in the United States. There is little data on the impact of metastatic cancer on the risk of hemorrhagic stroke or mortality among patients undergoing fibrinolytic therapy (FT) for acute PE. METHODS: Using the National Inpatient Sample (NIS) database, we extracted admissions with a primary diagnosis of acute pulmonary embolism that underwent FT from 2010 to 2014. We performed a case control matched analysis between patients with and without metastatic cancer. Our primary outcome of interest was Mortality and our secondary outcome of interest was hemorrhagic stroke (HS). RESULTS: Of the 883,183 patients with a primary diagnosis of acute PE between 2010 and 12014, 23,690 patients (2.7%) underwent FT. After exclusion, 22,592 patients were included in the analysis. Of these, 941 patients (4.2%) were reported to have metastatic cancer. There was a higher incidence of cerebrovascular accidents and intubation/mechanical ventilation in the metastatic cancer arm. Mortality was significantly higher in the metastatic cancer arm with no difference in the incidence of HS. In multivariate regression analysis, among all patients that underwent FT for acute PE, metastatic cancer was associated with a significant odds for mortality (OR 1.91, 95% CI 1.11-5.82, pâ¯<â¯.001). CONCLUSION: The presence of metastatic cancer in patients undergoing fibrinolytic therapy for acute pulmonary embolism is associated with increase mortality.

BACKGROUND: Pharmacologic reperfusion therapy is a recommended and effective strategy in patients with ST-elevation myocardial infarction (STEMI) when percutaneous coronary intervention (PCI) is not available. This study investigates temporal trends and outcomes of fibrinolytic therapy (FT) in elderly patients with STEMI. METHODS: Using the Nationwide Inpatient Sample database, we extracted patients ≥80 years a primary diagnosis of STEMI admitted between 2010 and 2014. Using ICD codes, we identified patients who underwent FT. We performed temporal trend analysis, then compared characteristics and inpatient outcomes in the FT group versus no-FT group. Our primary outcome of interest was hemorrhagic stroke (HS). We also assessed the impact of HS on mortality and discharge to skilled nursing facility (SNF). RESULTS: Of the 917,307 patients with STEMI, 16.1% (n = 147,874) were aged 80 or older. Primary PCI was performed in 46.2%, 2.4% underwent FT, and 51.3% had neither pharmacologic nor mechanical revascularization. The rate of FT increased (1.9%-2.4%) in a nonlinear trend over the five years of the study. The FT group was eight times more likely to suffer HS (P < 0.001). FT was an independent predictor of HS (OR 7.90, 95% CI 4.36-14.30; P < 0.001), whether they underwent PCI or not. HS was an independent predictor of mortality and SNF discharge. CONCLUSION: FT in patients 80 years or older presenting with STEMI was associated with an eight-fold increase in HS and no associated mortality advantage, both with or without PCI. These data underscore the increased risk of FT in the elderly.

AIMS: Invasive haemodynamic assessment with a pulmonary artery catheter is often used to guide the management of patients with cardiogenic shock (CS) and may provide important prognostic information. We aimed to assess prognostic associations and relationships to end-organ dysfunction of presenting haemodynamic parameters in CS. METHODS AND RESULTS: The Critical Care Cardiology Trials Network is an investigator-initiated multicenter registry of cardiac intensive care units (CICUs) in North America coordinated by the TIMI Study Group. Patients with CS (2018-2022) who underwent invasive haemodynamic assessment within 24 h of CICU admission were included. Associations of haemodynamic parameters with in-hospital mortality were assessed using logistic regression, and associations with presenting serum lactate were assessed using least squares means regression. Sensitivity analyses were performed excluding patients on temporary mechanical circulatory support and adjusted for vasoactive-inotropic score. Among the 3603 admissions with CS, 1473 had haemodynamic data collected within 24 h of CICU admission. The median cardiac index was 1.9 (25th-75th percentile, 1.6-2.4) L/min/m2 and mean arterial pressure (MAP) was 74 (66-86) mmHg. Parameters associated with mortality included low MAP, low systolic blood pressure, low systemic vascular resistance, elevated right atrial pressure (RAP), elevated RAP/pulmonary capillary wedge pressure ratio, and low pulmonary artery pulsatility index. These associations were generally consistent when controlling for the intensity of background pharmacologic and mechanical haemodynamic support. These parameters were also associated with higher presenting serum lactate. CONCLUSION: In a contemporary CS population, presenting haemodynamic parameters reflecting decreased systemic arterial tone and right ventricular dysfunction are associated with adverse outcomes and systemic hypoperfusion.

BACKGROUND: Care in the cardiovascular intensive care unit (CICU) has become increasingly intricate due to a temporal rise in noncardiac diagnoses and overall clinical complexity with high risk for short-term rehospitalization and mortality. Survivors of critical illness are often faced with debility and limitations extending beyond the index hospitalization. Comprehensive ICU recovery programs have demonstrated some efficacy but have primarily targeted survivors of acute respiratory distress syndrome or sepsis. The efficacy of dedicated ICU recovery programs on the CICU population is not defined. METHODS: We aim to describe the design and initial experience of a novel CICU-recovery clinic (CICURC). The primary outcome was death or rehospitalization in the first 30 days following hospital discharge. Self-reported outcome measures were performed to assess symptom burden and independence in activities of daily living. RESULTS: Using standardized criteria, 41 patients were referred to CICURC of which 78.1% established care and were followed for a median of 88 (56-122) days. On intake, patients reported a high burden of heart failure symptoms (KCCQ overall summary score 29.8 [18.0-47.5]), and nearly half (46.4%) were dependent on caretakers for activities of daily living. Thirty days postdischarge, no deaths were observed and the rate of rehospitalization for any cause was 12.2%. CONCLUSIONS: CICU survivors are faced with significant residual symptom burden, dependence upon caretakers, and impairments in mental health. Dedicated CICURCs may help prioritize treatment of ICU related illness, reduce symptom burden, and improve outcomes. Interventions delivered in ICU recovery clinic for patients surviving the CICU warrant further investigation.

Importance: Patients with ST-segment elevation myocardial infarction (STEMI) living in rural settings often have worse clinical outcomes compared with their urban counterparts. Whether this discrepancy is due to clinical characteristics or delays in timely reperfusion with primary percutaneous coronary intervention (PPCI) or fibrinolysis is unclear. Objective: To assess process metrics and outcomes among patients with STEMI in rural and urban settings across the US. Design, Setting, and Participants: This cross-sectional multicenter study analyzed data for 70â¯424 adult patients with STEMI from the National Cardiovascular Data Registry Chest Pain-MI Registry in 686 participating US hospitals between January 1, 2019, and June 30, 2020. Patients without a valid zip code were excluded, and those transferred to a different hospital during the course of the study were excluded from outcome analysis. Main Outcomes and Measures: In-hospital mortality and time-to-reperfusion metrics. Results: This study included 70â¯424 patients with STEMI (median [IQR] age, 63 [54-73] years; 49â¯850 [70.8%] male and 20â¯574 [29.2%] female; patient self-reported race: 6753 [9.6%] Black, 60â¯114 [85.4%] White, and 2096 [3.0%] of another race [including American Indian, Alaskan Native, Native Hawaiian, and Pacific Islander]; 5281 [7.5%] individuals of Hispanic or Latino ethnicity) in 686 hospitals (50â¯702 [72.0%] living in urban zip codes and 19â¯722 [28.0%] in rural zip codes). Patients from rural settings were less likely to undergo PPCI compared with patients from urban settings (14â¯443 [73.2%] vs 43â¯142 [85.1%], respectively; P < .001) and more often received fibrinolytics (2848 [19.7%] vs 937 [2.7%]; P < .001). Compared with patients from urban settings, those in rural settings undergoing PPCI had longer median (IQR) time from first medical contact to catheterization laboratory activation (30 [12-42] minutes vs 22 [15-59] minutes; P < .001) and longer median (IQR) time from first medical contact to device (99 minutes [75-131] vs 81 [66-103] minutes; P < .001), including those who arrived directly at PPCI centers (83 [66-107] minutes vs 78 [64-97] minutes; P < .001) and those who transferred to PPCI centers from another treatment center (125 [102-163] minutes vs 103 [85-135] minutes; P < .001). Among those who transferred in, median (IQR) door-in-door-out time was longer in patients from rural settings (63 [41-100] minutes vs 50 [35-80] minutes; P < .001). Out-of-hospital cardiac arrest was more common in patients from urban vs rural settings (3099 [6.1%] vs 958 [4.9%]; P < .001), and patients from urban settings were more likely to present with heart failure (4112 [8.1%] vs 1314 [6.7%]; P < .001). After multivariable adjustment, there was no significant difference in in-hospital mortality between rural and urban groups (adjusted odds ratio, 0.97; 95% CI, 0.89-1.06). Conclusions and Relevance: In this large cohort of patients with STEMI from US hospitals participating in the National Cardiovascular Data Registry Chest Pain-MI Registry, patients living in rural settings had longer times to reperfusion, were less likely to receive PPCI or meet guideline-recommended time to reperfusion, and more frequently received fibrinolytics than patients living in urban settings. However, there was no difference in adjusted in-hospital mortality between patients with STEMI from urban and rural settings.

BACKGROUND: Hemodynamic values from right heart catheterization aid diagnosis and clinical decision-making but may not predict outcomes. Mixed venous oxygen saturation percentage and pulmonary capillary wedge pressure relate to cardiac output and congestion, respectively. We theorized that a novel, simple ratio of these measurements could estimate cardiovascular prognosis. METHODS: We queried Veterans Affairs' databases for clinical, hemodynamic, and outcome data. Using the index right heart catheterization between 2010 and 2016, we calculated the ratio of mixed venous oxygen saturation-to-pulmonary capillary wedge pressure, termed ratio of saturation-to-wedge (RSW). The primary outcome was time to all-cause mortality; secondary outcome was 1-year urgent heart failure presentation. Patients were stratified into quartiles of RSW, Fick cardiac index (CI), thermodilution CI, and pulmonary capillary wedge pressure alone. Kaplan-Meier curves and Cox proportional hazards models related comparators with outcomes. RESULTS: Of 12 019 patients meeting inclusion criteria, 9826 had values to calculate RSW (median 4.00, interquartile range, 2.67-6.05). Kaplan-Meier curves showed early, sustained separation by RSW strata. Cox modeling estimated that increasing RSW by 50% decreases mortality hazard by 19% (estimated hazard ratio, 0.81 [95% CI, 0.79-0.83], P<0.001) and secondary outcome hazard by 28% (hazard ratio, 0.72 [95% CI, 0.70-0.74], P<0.001). Among the 3793 patients with data for all comparators, Cox models showed RSW best associated with outcomes (by both C statistics and Bayes factors). Furthermore, pulmonary capillary wedge pressure was superior to thermodilution CI and Fick CI. Multivariable adjustment attenuated without eliminating the association of RSW with outcomes. CONCLUSIONS: In a large national database, RSW was superior to conventional right heart catheterization indices at assessing risk of mortality and urgent heart failure presentation. This simple calculation with routine data may contribute to clinical decision-making in this population.

RESUMO
OBJECTIVES: Patients with cirrhosis have increased bleeding risk due to coagulopathy and platelet sequestration, as well as inherent cardiovascular risk. We aim to assess the impact of cirrhosis on the revascularization rates and in-hospital outcomes in patients with acute myocardial infarction (AMI). METHODS: We queried the National Inpatient Sample Database from 2010 to 2014 and identified hospitalizations with a primary diagnosis of AMI (n = 612,547); of these, a total of 3135 patients had a concomitant diagnosis of cirrhosis. We compared clinical outcomes between patients with cirrhosis and a propensity-score matched cohort without cirrhosis (n = 3086). RESULTS: Patients with cirrhosis had a lower rate of ST-elevation MI (18.9% vs 26.7% in the cohort with no cirrhosis; P<.001), a lower rate of coronary angiography (51.4% vs 63.9% in the cohort with no cirrhosis; P<.001), and lower rates of revascularization by percutaneous coronary intervention (PCI) (28.7% vs 39.2% in the cohort with no cirrhosis; P<.001) or coronary artery bypass grafting (6.0% vs 12.9% in the cohort with no cirrhosis; P<.001). Gastrointestinal and postprocedural hemorrhage was more common in patients with cirrhosis (12.3% vs 7.1% in the cohort with no cirrhosis; P<.001), regardless of revascularization status, and cirrhosis patients also had a higher in-hospital mortality rate (8.7% vs 6.9% in the cohort with no cirrhosis; P<.01). PCI was independently associated with lower mortality in patients with cirrhosis (odds ratio, 0.57; 95% confidence interval, 0.33-0.98; P=.04). CONCLUSION: Patients with cirrhosis presenting with AMI were highly selected to undergo coronary angiography and subsequent revascularization, and had higher mortality than those without cirrhosis. However, PCI was independently associated with lower mortality in patients with cirrhosis, although to less effect than non-cirrhotics, perhaps due to higher bleeding rates.

Hemorrhagic stroke (HS) is a feared complication of Fibrinolytic therapy (FT). Risk assessment scores may help in risk stratification to reduce this complication. Patients (admissions) ≥18 years with a primary diagnosis of ST-elevation myocardial infarction (STEMI) who received systemic thrombolysis were extracted from Nationwide Inpatient Sample database and stratified and compared based on CHA2DS2VASC score 0 to 3, 4 to 6, and 7 to 9 as low, intermediate and high risk, respectively. The primary outcomes of interest were HS and mortality. We performed logistic regression analysis with a composite of HS and mortality as the primary end point. Of the 917,307 admissions with a primary diagnosis of STEMI, 39,579 (4.3%) underwent FT. The median score was 3 (interquartile range 1 to 5). The rate of HS significantly increased in the risk category compared with the low and intermediate groups (0.5% and 0.6% vs 4.1%; p <0.001). Mortality increased with increasing risk category (3.8% vs 10.5% vs 20.7%; p <0.001). Compared with the low-risk group patients in the intermediate (odds ratio 2.11 95% confidence interval [CI] 1.56 to 2.85; p <0.001) and high risk groups (odds ratio 3.47 95% CI 1.68 to 7.2; p <0.001) were more likely to experience the composite end point of HS or inpatient mortality. CHA2DS2VASC score performed better at predicting mortality (area under curve 0.67, 95% CI 0.64 to 0.7; p = 0.014) than HS (area under curve 0.6 95% CI 0.52 to 0.69; p = 0.021). In conclusion, patients with high CHA2DS2VASC score (7 to 9) are at a higher risk of hemorrhagic stroke and death after FT for STEMI. CHA2DS2VASC score performed better at predicting mortality than hemorrhagic stroke in this cohort.
