Relationship between the HeartMate Risk Score category on admission and outcome in patients with acute heart failure referred to a cardiac intensive care unit.

The HeartMate Risk Score (HMRS), a simple clinical prediction rule based on the patients' age, albumin, creatinine, and the international normalized ratio of the prothrombin time (PT-INR), is correlated with mortality in the cohort of left ventricular assist device (LVAD) recipients. However, in an aging society, an LAVD is indicated for only a small proportion of patients with acute heart failure (AHF), and whether the HMRS has prognostic implications for unselected patients with AHF is unknown. This study aimed to assess the prognostic value of HMRS categories on admission in patients with AHF. We analyzed 339 hospitalized patients with AHF who had albumin, creatinine, and the PT-INR recorded on admission. The patients were categorized as follows: the High group (HMRS > 2.48, n = 131), Mid group (HMRS of 1.58-2.48, n = 97) group, and Low group (HMRS < 1.58, n = 111). The endpoints of this study were all-cause death and readmission for heart failure (HF). During a median follow-up of 247 days, 24 (18.3%) patients died in the High group, 7 (7.2%) died in the Mid group, and 8 (7.2%) died in the Low group. In a multivariable analysis adjusted for highly imbalanced baseline variables, a high HMRS was independently associated with survival, with a hazard ratio of 2.90 (95% confidence interval 1.42-5.96, P = 0.004). With regard to the composite endpoint of all-cause death and readmission for HF, the Mid group had a worse prognosis than the Low group, and the High group had the worst prognosis. A high HMRS on admission is associated with all-cause mortality and readmission for HF, and a mid-HMRS is associated with readmission for HF after AHF hospitalization. The HMRS may be a valid clinical tool to stratify the risk of adverse outcomes after hospitalization in unselected patients with AHF.

A Pediatric Interprofessional Cardiac Intensive Care Unit Intervention: CICU Teams and Loved Ones Communicating (CICU TALC) is Feasible, Acceptable, and Improves Clinician Communication Behaviors in Family Meetings.

Parents of children in the pediatric cardiac intensive care unit (CICU) are often unprepared for family meetings (FM). Clinicians often do not follow best practices for communicating with families, adding to distress. An interprofessional team intervention for FM is feasible, acceptable, and positively impacts family preparation and conduct of FM in the CICU. We implemented a family- and team-support intervention for conducting FM and conducted a pretest-posttest study with parents of patients selected for a FM and clinicians. We measured feasibility, fidelity to intervention protocol, and parent acceptability via questionnaire and semi-structured interviews. Clinician behavior in meetings was assessed through semantic content analyses of meeting transcripts tracking elicitation of parental concerns, questions asked of parents, and responses to parental empathic opportunities. Logistic and ordinal logistic regression assessed intervention impact on clinician communication behaviors in meetings comparing pre- and post-intervention data. Sixty parents (95% of approached) were enrolled, with collection of 97% FM and 98% questionnaire data. We accomplished > 85% fidelity to intervention protocol. Most parents (80%) said the preparation worksheet had the right amount of information and felt positive about families receiving this worksheet. Clinicians were more likely to elicit parental concerns (adjusted odds ratio = 3.42; 95%CI [1.13, 11.0]) in post-intervention FM. There were no significant differences in remaining measures. Implementing an interprofessional team intervention to improve family preparation and conduct of FM is locally feasible, acceptable, and changes clinician behaviors. Future research should assess broader impact of training on clinicians, patients, and families.

Approach to red blood cell transfusions in post-operative congenital heart disease surgery patients: when to stop?

BACKGROUND: The best transfusion approach for CHD surgery is controversial. Studies suggest two strategies: liberal (haemoglobin ≤ 9.5 g/dL) and restrictive (waiting for transfusion until haemoglobin ≤ 7.0 g/dL if the patient is stable). Here we compare liberal and restrictive transfusion in post-operative CHD patients in a cardiac intensive care unit. METHODS: Retrospective analysis was conducted on CHD patients who received liberal transfusion (2019-2021, n=53) and restrictive transfusion (2021-2022, n=43). RESULTS: The two groups were similar in terms of age, gender, Paediatric Risk of Mortality-3 score, Paediatric Logistic Organ Dysfunction-2 score, Risk Adjustment for Congenital Heart Surgery-1 score, cardiopulmonary bypass time, vasoactive inotropic score, total fluid balance, mechanical ventilation duration, length of cardiac intensive care unit stay, and mortality. The liberal transfusion group had a higher pre-operative haemoglobin level than the restrictive group (p < 0.05), with no differences in pre-operative anaemia. Regarding the minimum and maximum post-operative haemoglobin levels during a cardiac intensive care unit stay, the liberal group had higher haemoglobin levels in both cases (p<0.01 and p=0.019, respectively). The number of red blood cell transfusions received by the liberal group was higher than that of the restrictive group (p < 0.001). There were no differences between the two groups regarding lactate levels at the time of and after red blood cell transfusion. The incidence of bleeding, re-operation, acute kidney injury, dialysis, sepsis, and systemic inflammatory response syndrome was similar. CONCLUSIONS: Restrictive transfusion may be preferable over liberal transfusion. Achieving similar outcomes with restrictive transfusions may provide promising evidence for future studies.

Parental communication satisfaction with the clinical team in the paediatric cardiac ICU.

INTRODUCTION: Understanding parents' communication preferences and how parental and child characteristics impact satisfaction with communication is vital to mitigate communication challenges in the cardiac ICU. METHODS: This cross-sectional survey was conducted from January 2019 to March 2020 in a paediatric cardiac ICU with parents of patients admitted for at least two weeks. Family satisfaction with communication with the medical team was measured using the Communication Assessment Tool for Team settings. Clinical characteristics were collected via Epic, Pediatric Cardiac Critical Care Consortium local entry and Society for Thoracic Surgeons Congenital Heart Surgery Databases. Associations between communication score and parental mood, stress, perceptions of clinical care, and demographic characteristics along with patient demographic and clinical characteristics were examined. Multivariable ordinal models were conducted with characteristics significant in bivariate analysis. RESULTS: In total, 93 parents of 84 patients (86% of approached) completed surveys. Parents were 63% female and 70% White. Seventy per cent of patients were <6 months old at admission, 25% had an extracardiac abnormality, and 80% had a cardiac surgery this admission. Parents of children with higher pre-surgical risk of mortality scores (OR 2.875; 95%CI 1.076-7.678), presence of surgical complications (72 [63.0, 75.0] vs. 64 [95%CI 54.6, 73] (p = 0.0247)), and greater satisfaction with care in the ICU (r = 0.93922; p < 0.0001) had significantly higher communication scores. CONCLUSION: These findings can prepare providers for scenarios with higher risk for communication challenges and demonstrate the need for further investigation into interventions that reduce parental anxiety and improve communication for patients with unexpected clinical trajectories.

The impact of delirium on clinical and functional outcomes in hospitalized patients with acute coronary syndrome.

BACKGROUND: Delirium, which is prevalent in critical care settings, remains underexplored in acute coronary syndrome (ACS) patients in the cardiac intensive care unit (CICU). AIMS: To investigate the prevalence and clinical significance of delirium in patients with ACS admitted to the CICU. STUDY DESIGN: A prospective study (n = 106, mean age 74.2 ± 5.7 years) assessed delirium using the confusion assessment method-intensive care unit (CAM-ICU) tool in 21.7% of ACS patients during their CICU stay. Baseline characteristics, geriatric conditions and clinical procedures were compared between delirious and nondelirious patients. The outcomes included in-hospital mortality, 30-day and 6-month mortality, acute adverse events and length of CICU stay and hospital stay (LOS). RESULTS: Delirious patients who were older and had a higher incidence of coronary artery disease underwent more complex procedures (e.g., pacemaker placement). Multivariate analysis identified central venous catheter insertion, urinary catheterization and benzodiazepine use as independent predictors of delirium. Delirium was correlated with prolonged LOS (p < .001) and increased in-hospital, 30-day and 6-month mortality (p < .001). CONCLUSIONS: Delirium in ACS patients in the CICU extends hospitalization and increases in-hospital, 30-day and 6-month mortality. Early recognition and targeted interventions are crucial for mitigating adverse outcomes in this high-risk population. RELEVANCE TO CLINICAL PRACTICE: This study highlights the critical impact of delirium on outcomes in hospitalized patients with ACS in the CICU. Delirium, often overlooked in ACS management, significantly extends hospitalization and increases mortality rates. Nurses and physicians must be vigilant in identifying delirium early, particularly in older ACS patients or those with comorbidities. Recognizing independent predictors such as catheterization and benzodiazepine use allows for targeted interventions to reduce delirium incidence. Integrating routine delirium assessments and preventive strategies into ACS management protocols can improve outcomes, optimize resource utilization and enhance overall patient care in the CICU setting.

Planned Reoperation after Cardiac Surgery in the Cardiac Intensive Care Unit.

Background: Cardiac surgical re-exploration for bleeding is associated with increased morbidity and mortality. Whether to perform these procedures in the operating room (OR) or the Cardiac Intensive Care Unit (CICU) in uncertain. We sought to determine if the location of the reoperation would affect postoperative outcomes when a reoperation for bleeding is required following cardiac surgery. Methods: Patients who underwent planned cardiac re-explorations for bleeding at our center from January 2019 to December 2021 were retrospectively enrolled in this study. Patient outcomes were compared and analyzed. Results: Due to hemorrhagic shock, 72 patients underwent planned cardiac re-explorations, including 21 operated in the CICU and 51 in the OR. Within 12 h of the primary operation, 65 re-explorations (90.3%) were performed. The peak Vasoactive-Inotropic Score was 47.0 ± 27.4, systolic blood pressure was 89.4 ± 9.6 mmHg, central venous pressure was 12.1 ± 4.4 cmH 2 O, and the serum lactate was 5.5 ± 4.1 mmol/L prior to the reoperation. Multivariate logistic analysis showed that a reoperation performed in the CICU was not an independent risk factor for the occurrence of major complications. There was no significant difference in mortality between the two groups. Conclusions: Planned re-exploration for bleeding following open cardiac surgery in the CICU is feasible and safe.

Utility of nuclear cardiovascular imaging in the cardiac intensive care unit.

The contemporary Cardiac Intensive Care Unit (CICU) has evolved into a complex unit that admits a heterogeneous mix of patients with a wide range of acute cardiovascular diseases often complicated by multi-organ failure. Although electrocardiography (ECG) and echocardiography are well-established as first-line diagnostic modalities for assessing patients in the CICU, nuclear cardiology imaging has emerged as a useful adjunctive diagnostic modality. The versatility, safety and accuracy of nuclear imaging (e.g., perfusion, metabolism, inflammation) for the assessment of patient with coronary artery disease, ventricular arrhythmias, infiltrative cardiomyopathies, infective endocarditis and inflammatory aortopathies has been proven useful and now often incorporated into the best practices for the management of critically ill cardiac patients. Thus, clinicians must familiarize themselves with the value and current and future applications of nuclear imaging in the management of the cardiac patient in the CICU.

Dexmedetomidine as an anesthetic adjunct is associated with reduced complications and cardiac intensive care unit length of stay after heart valve surgery.

BACKGROUND: We sought to explore the relationship between dexmedetomidine as an anesthetic adjuvant in cardiac surgery and postoperative complications and length of stay (LOS) in the cardiac intensive care unit (CICU). METHODS: We conducted a retrospective study of patients aged 18 years and older who underwent heart valve surgery between October 2020 and June 2022. The primary endpoint of the study was major postoperative complications (cardiac arrest, atrial fibrillation, myocardial injury/infarction, heart failure) and the secondary endpoint was prolonged CICU LOS (defined as LOS > 90th percentile). Multivariate logistic regression analysis was performed for variables that were significant in the univariate analysis. RESULTS: A total of 856 patients entered our study. The 283 patients who experienced the primary and secondary endpoints were included in the adverse outcomes group, and the remaining 573 were included in the prognostic control group. Multivariate logistic regression analysis revealed that age > 60 years (odds ratio [OR], 1.68; 95% confidence interval [CI], 1.23-2.31; p < 0.01), cardiopulmonary bypass (CPB) > 180 min (OR, 1.62; 95% CI, 1.03-2.55; p = 0.04) and postoperative mechanical ventilation time > 10 h (OR, 1.84; 95% CI, 1.35-2.52; p < 0.01) were independent risk factors for major postoperative complications; Age > 60 years (OR, 3.20; 95% CI, 1.65-6.20; p < 0.01), preoperative NYHA class 4 (OR, 4.03; 95% CI, 1.74-9.33; p < 0.01), diabetes mellitus (OR, 2.57; 95% CI, 1.22-5.41; p = 0.01), Intraoperative red blood cell (RBC) transfusion > 650 ml (OR, 2.04; 95% CI, 1.13-3.66; p = 0.02), Intraoperative bleeding > 1200 ml (OR, 2.69; 95% CI, 1.42-5.12; p < 0.01) were independent risk factors for prolonged CICU length of stay. Intraoperative use of dexmedetomidine as an anesthetic adjunct was a protective factor for major complications (odds ratio, 0.51; 95% confidence interval, 0.35-0.74; p < 0.01) and prolonged CICU stay. (odds ratio, 0.37; 95% confidence interval, 0.19-0.73; p < 0.01). CONCLUSIONS: In patients undergoing heart valve surgery, age, duration of cardiopulmonary bypass, and duration of mechanical ventilation are associated with major postoperative complication. Age, preoperative NYHA classification 4, diabetes mellitus, intraoperative bleeding, and RBC transfusion are associated with increased CICU length of stay. Intraoperative use of dexmedetomidine may improve such clinical outcomes.

Outcomes and Predictors of Mortality Among Cardiac Intensive Care Unit Patients With Heart Failure.

BACKGROUND: Little is known regarding the causes of critical illness and determinants of prognosis of patients with heart failure (HF) admitted to the modern cardiac intensive care unit (CICU). We sought to describe the epidemiology and outcomes of patients with HF admitted to the contemporary CICU. METHODS AND RESULTS: Retrospective cohort analysis of Mayo Clinic CICU patients admitted with HF from 2007 to 2018 who had left ventricular ejection fraction (LVEF) data. HF with reduced LVEF (HFrEF) was defined as a LVEF of less than 50%, and HF with preserved LVEF (HFpEF) as a LVEF of 50% or greater. In-hospital mortality was analyzed using multivariable logistic regression. Survival to 1 year was analyzed using a Kaplan-Meier analysis. We included 4012 patients, including 67.8% with HFrEF and 32.2% with HFpEF. Patients with HFrEF and HFpEF were comparable and had equivalent severity of illness. Critical care therapies were used in 59.4%, with a slight preponderance in patients with HFrEF. In-hospital mortality occurred in 12.5% of patients and was similar in HFrEF vs HFpEF. Shock and cardiac arrest were the strongest predictors of adjusted in-hospital mortality, followed by Braden skin score and serum chloride level; patients with HFrEF and HFpEF had similar adjusted mortality rates. The 1-year survival after hospital discharge was 74.5% and was slightly lower for patients with HFpEF. All-cause rehospitalization occurred in 36.6%, and 52.8% of hospital survivors died or were readmitted within 1 year. CONCLUSIONS: CICU patients with HF have a substantial burden of critical illness, high use of critical care therapies, and poor outcomes regardless of LVEF. This finding emphasizes the potential unmet care needs in this cohort. LAY SUMMARY: Patients with heart failure who require admission to the cardiac intensive care unit have high severity of illness and are at significant risk of death during and after hospitalization. These patients often require specialized critical care therapies to treat manifestations of critical illness. Patients who are admitted with cardiac arrest or shock, including those who require mechanical ventilation or vasopressors, are at particularly high risk of death. Patients' left ventricular ejection fraction is not strongly associated with the risk of death when accounting for other major predictors including frailty and laboratory abnormalities.

The Road Not Yet Traveled: Distinction in Critical Care Cardiology through the Advanced Heart Failure and Transplant Cardiology Training Pathway.

As the acuity, complexity, and illness severity of patients admitted to cardiac intensive care units have increased, the need to recognize critical care cardiology (CCC) as a dedicated subspecialty in cardiovascular disease has received increasing support. Differing viewpoints exist regarding the optimal pathway for CCC training. Currently, all proposed CCC training pathways involve permutations of individual training years culminating in subspecialty certification across multiple disciplines; however, there are significant disadvantages to these training paradigms. We propose an innovative, pragmatic approach to CCC training through tailored subspecialty training in advanced heart failure and transplant cardiology (AHFTC), using elective time to enrich AHFTC training with skills and experiences necessary to become a highly skilled critical care cardiologist. The completion of this pathway would lead to completion of AHFTC training with a novel designation: distinction in critical care cardiology.

Validation of cardiogenic shock phenotypes in a mixed cardiac intensive care unit population.

BACKGROUND: Proposed phenotypes have recently been identified in cardiogenic shock (CS) populations using unsupervised machine learning clustering methods. We sought to validate these phenotypes in a mixed cardiac intensive care unit (CICU) population of patients with CS. METHODS: We included Mayo Clinic CICU patients admitted from 2007 to 2018 with CS. Agnostic K means clustering was used to assign patients to three clusters based on admission values of estimated glomerular filtration rate, bicarbonate, alanine aminotransferase, lactate, platelets, and white blood cell count. In-hospital mortality and 1-year mortality were analyzed using logistic regression and Cox proportional-hazards models, respectively. RESULTS: We included 1498 CS patients with a mean age of 67.8 ± 13.9 years, and 37.1% were females. The acute coronary syndrome was present in 57.3%, and cardiac arrest was present in 34.0%. Patients were assigned to clusters as follows: Cluster 1 (noncongested), 603 (40.2%); Cluster 2 (cardiorenal), 452 (30.2%); and Cluster 3 (hemometabolic), 443 (29.6%). Clinical, laboratory, and echocardiographic characteristics differed across clusters, with the greatest illness severity in Cluster 3. Cluster assignment was associated with in-hospital mortality across subgroups. In-hospital mortality was higher in Cluster 3 (adjusted odds ratio [OR]: 2.6 vs. Cluster 1 and adjusted OR: 2.0 vs. Cluster 2, both p < 0.001). Adjusted 1-year mortality was incrementally higher in Cluster 3 versus Cluster 2 versus Cluster 1 (all p < 0.01). CONCLUSIONS: We observed similar phenotypes in CICU patients with CS as previously reported, identifying a gradient in both in-hospital and 1-year mortality by cluster. Identifying these clinical phenotypes can improve mortality risk stratification for CS patients beyond standard measures.

Trends in Therapy and Outcomes Associated With Respiratory Failure in Patients Admitted to the Cardiac Intensive Care Unit.

PURPOSE: To describe the epidemiology, outcomes, and temporal trends of respiratory failure in the cardiac intensive care unit (CICU). MATERIALS AND METHODS: Retrospective cohort analysis of 2,986 unique Mayo Clinic CICU patients from 2007 to 2018 with respiratory failure. Temporal trends were analyzed, along with hospital and 1-year mortality. Multivariable logistic regression was used to determine adjusted hospital mortality trends. RESULTS: The prevalence of respiratory failure in the CICU increased from 15% to 38% during the study period (P < 0.001 for trend). Among patients with respiratory failure, the utilization of invasive ventilation decreased and noninvasive ventilation modalities increased over time. Hospital mortality and 1-year mortality were 24% and 54%, respectively, with variation according to the type of respiratory support (highest among patients receiving invasive ventilation alone: 35% and 46%, respectively). Hospital mortality was highest among patients with concomitant cardiac arrest and/or shock (52% for patients with both). Hospital mortality decreased in the overall population from 35% to 25% (P < 0.001 for trend), but was unchanged among patients receiving positive-pressure ventilation. CONCLUSIONS: The prevalence of respiratory failure in CICU more than doubled during the last decade. The use of noninvasive respiratory support increased, while overall mortality declined over time. Cardiac arrest and shock accounted for the majority of deaths. Further research is needed to optimize the outcomes of high-risk CICU patients with respiratory failure.

Similarities in extracorporeal membrane oxygenation management across intensive care unit types in the United States: An analysis of the Extracorporeal Life Support Organization Registry.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) use in the United States occurs often in cardiothoracic ICUs (CTICU). It is unknown how it varies across ICU types. METHODS: We identified 10 893 ECMO runs from the Extracorporeal Life Support Organization (ELSO) Registry across 2018 and 2019. Primary outcome was ECMO case volume by ICU type (CTICU vs. non-CTICU). Adjusting for pre-ECMO characteristics and case mix, secondary outcomes were on-ECMO physiologic variables by ICU location stratified by support type. RESULTS: CTICU ECMO occurred in 65.1% and 55.1% (2018 and 2019) of total runs. A minority of total runs related to cardiac surgery procedures (CTICU: 21.7% [2018], 18% [2019]; non-CTICU: 11.2% [2018], 13% [2019]). After multivariate adjustment, non-CTICU ECMO for cardiac support associated with lower 4- and 24-h circuit flow (3.9 liters per minute [LPM] vs. 4.1 LPM, p < 0.0001; 4.1 LPM vs. 4.3 LPM, p < 0.0001); for respiratory support, lower on-ECMO mean fraction of inspired oxygen ([Fi O2 ], 67% vs. 69%, p = 0.02) and lower respiratory rate (14 vs. 15, p < 0.0001); and, for extracorporeal cardiopulmonary resuscitation (ECPR), lower ECMO flow rates at 24 h (3.5 LPM vs. 3.7 LPM, p = 0.01). CONCLUSIONS: ECMO mostly remains in CTICUs though a minority is associated with cardiac surgery. Statistically significant but clinically minor differences in on-ECMO metrics were observed across ICU types.

Evaluation of potentially inappropriate medications in older patients admitted to the cardiac intensive care unit according to the 2019 Beers criteria, STOPP criteria version 2 and Chinese criteria.

WHAT IS KNOWN AND OBJECTIVES: Potential inappropriate medications (PIMs) can increase the risk of medication-induced harm. However, there are no studies regarding PIMs in older and critically ill patients with cardiovascular diseases in China. Therefore, studies evaluating PIMs in these patients can help in the implementation of more effective interventions to reduce the risk of drug use. Our objective was to analyse the prevalence of PIMs in elderly patients admitted to the cardiac intensive care unit (CICU) comparing the 2019 Beers criteria (Beers criteria), Screening Tool of Older People's Potentially Inappropriate Prescriptions (STOPP) criteria version 2 (STOPP criteria) and criteria of potentially inappropriate medications for older adults in China (Chinese criteria); and analyse the factors influencing the PIMs. METHODS: This cross-sectional and retrospective study was performed with elderly patients (≥65 years) admitted to the CICU of the Beijing Tongren Hospital in China from January 2019 to June 2020. The PIMs were identified based on the Chinese, STOPP and Beers criteria at admission and discharge. The three criteria were compared using the Kappa statistic. Multiple regression analysis was used to investigate the influencing factors associated with PIMs. RESULTS AND DISCUSSION: A total of 369 patients who met the inclusion/exclusion criteria were included in this study. According to the three criteria used to evaluate the PIMs, the prevalence was 78.3% and 72.6% at admission and discharge, respectively. The prevalence rate of PIMs determined by the Chinese criteria was 62.1% at admission versus 56.6% at discharge (p = 0.134); the Beers criteria was 53.9% at admission versus 46.9% at discharge (p = 0.056); by the STOPP criteria was 20.6% at admission versus 13.8% at discharge (p = 0.015). Moreover, 28.9% (STOPP criteria), 56.8% (Beers criteria) and 73.4% (Chinese criteria) of patients taking PIMs on admission still had the same problem at discharge. The most common PIMs screened by the Beers, STOPP and Chinese criteria were diuretics, benzodiazepines and clopidogrel, respectively. Besides, the three criteria showed poor agreement. Finally, the stronger predictor of PIMs was the increased number of medications (p < 0.05). WHAT IS NEW AND CONCLUSION: The prevalence of PIMs in elderly patients admitted to the CICU was high. The Chinese, STOPP and Beers criteria are effective screening tools to detect PIMs, but the consistency between them was poor. The increased number of medications was a significant predictor of PIMs.

Distress among hospitalized patients with acute coronary syndrome.

BACKGROUND: Previous studies have demonstrated that those suffering from acute coronary syndrome (ACS) experience various physical and psychological symptoms. Few studies have investigated the multi-factorial, holistic, unpleasant experience of distress that includes physical, psychological, social, and spiritual factors among this patient population while still hospitalized. AIM: To describe the level of distress among patients hospitalized with ACS and its association with demographic and clinical factors and mortality. STUDY DESIGN: The study conducted a descriptive, cross-sectional survey. METHODS: The Acute Coronary Syndrome Israel Study is a national, biennial registry, enrolling all patients with ACS admitted to cardiac intensive care or cardiology wards in Israel within a 2-month period. Demographic and clinical data were retrieved from an electronic database. Distress was measured by the Distress Thermometer. Nurses collected distress data directly from patients before discharge. RESULTS: Nine hundred ninety participants (50.6% response rate) were surveyed. Mean age was 62.8 (SD = 12.5). Mean distress level was 4.8 (SD = 3.45) out of 10. The most frequently reported area of distress was physical, followed by emotional. Practical and family problems were less frequent. Emotional distress was found to differ based on educational level, marital status, smoking history, and previous medical history. Distress did not predict 7- or 30-day mortality. CONCLUSIONS: Respondents with ACS were in moderate distress. It is recommended that those at increased risk receive increased monitoring of emotional distress while still in hospital. Further studies should investigate this holistic view of distress among the ACS population using a variety of methods and methodologies.

Veno-Arterial Extracorporeal Membrane Oxygenation in Patients with Fulminant Myocarditis: A Review of Contemporary Literature.

Fulminant myocarditis is characterized by life threatening heart failure presenting as cardiogenic shock requiring inotropic or mechanical circulatory support to maintain tissue perfusion. There are limited data on the role of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in the management of fulminant myocarditis. This review seeks to evaluate the management of fulminant myocarditis with a special emphasis on the role and outcomes with VA-ECMO use.

Incidence and outcomes of acute kidney injury stratified by cardiogenic shock severity.

BACKGROUND: Acute kidney injury (AKI) is common among patients with cardiogenic shock (CS) and it is independently associated with mortality. We sought to assess the prevalence, severity, and prognosis of AKI as a function of cardiogenic shock severity in unselected Cardiac Intensive Care Unit (CICU) patients. METHODS: We retrospectively reviewed admissions to the Mayo Clinic between 2007 to 2015 and stratified patients by the AKI stage (based on modified Kidney Disease: Improving Global Outcomes criteria) and Society for cardiovascular angiography and interventions (SCAI) shock stage. The association with in-hospital mortality was analyzed using multivariable logistic regression. RESULTS: We included 9,311 unique patients with a mean age of 67 years and 37% females. SCAI shock stages A, B, C, D, and E were present in 47%, 30%, 15%, 7%, and 1% of patients. The incidence of AKI of any severity was 39% in the CICU and 51% during the hospitalization. Hospital mortality occurred in 8% of all patients, and the risk increased as a function of the rising AKI and SCAI shock stage. Worsening AKI stage was associated with increased adjusted hospital mortality (adjusted OR per AKI stage 1.22, 95% CI 1.10-1.36, p < .001). Higher AKI stages were associated with increased adjusted hospital mortality in SCAI stage A/B (p < .001), but not in SCAI stage C, D, or E (all p > .05). CONCLUSIONS: Higher AKI stages were independently associated with mortality in CICU patients after accounting for shock severity and may add incremental prognostic utility in patients with lower SCAI stages.

Association Between Albumin Level and Mortality Among Cardiac Intensive Care Unit Patients.

PURPOSE: To study the effect of hypoalbuminemia on short- and long-term mortality in Cardiac Intensive Care Unit (CICU) patients. METHODS: We reviewed 12,418 unique CICU patients from 2007 to 2018. Hypoalbuminemia was defined as an admission albumin level <3.5 g/dL. Predictors of hospital mortality were identified using multivariable logistic regression. RESULTS: We included 2,680 patients (22%) with a measured admission albumin level. The median age was 68 (39% females). Admission diagnoses included acute coronary syndrome, heart failure, cardiac arrest, and cardiogenic shock. The median albumin level was 3.4 g/dL and 55% of patients had hypoalbuminemia. Hospital mortality occurred in 16%, and patients with hypoalbuminemia had higher hospital mortality (21% vs. 9%, adjusted OR 2.64, 95% CI 2.09-3.34, p < 0.001). Albumin level was inversely associated with hospital mortality (adjusted OR 0.60 per 1 g/dL higher albumin level, 95% CI 0.47-0.75, p <0.001), with a stepwise increase in the hospital mortality at lower albumin levels. Post-discharge mortality was higher in hospital survivors with hypoalbuminemia, and increased as a function of lower albumin levels. CONCLUSION: Hypoalbuminemia is common in CICU patients and associated with higher short- and long-term mortality. Progressively lower serum albumin was incrementally associated with higher hospital and post-discharge mortality.

Early Mobilization in Older Adults with Acute Cardiovascular Disease.

BACKGROUND: Early mobilization (EM) is beneficial in critical care units and in older hospitalized patients, but little is known about EM in older adults with acute cardiovascular disease. METHODS: Consecutive admissions of adults ≥80 years old to a Cardiac Intensive Care Unit (CICU) prior to and following implementation of a nurse-driven EM program were reviewed. Mobility was measured using the Level of Function (LOF) Mobility Scale, which ranges from 0 (bed immobile) to 5 (able to walk >20 meters). The primary outcome was discharge home. RESULTS: There were 412 patients included (N = 234, intervention; N = 178, preintervention). There was no difference in age between groups (overall 86.3 ± 4.8 years old) or sex (overall female N = 215, 52.2%). In the intervention group, functional impairment was present in 89 patients (38.0%) prehospitalization and in 209 patients (89.3%) on admission. Nearly half of patients (N = 107; 45.7%) improved their LOF by ≥1 during admission. Mobilization occurred during nearly all opportunities (838/850; 98.6%), and most mobility activities were completed (2,207/2,553; 86.4%). Adverse events were rare (5/2,207 activities [0.2% adverse event rate]) and transient. Patients in the intervention group were more likely than patients in the preintervention group to be discharged home (74.4 vs. 65.7%, P = 0.047, respectively) and had a lower rate of in-hospital death (6.4 vs. 14.6%, P = 0.006, respectively). There was no difference in mean length of hospital stay, 30-day emergency department visit or hospital re-admission. CONCLUSION: EM is safe in older adults in the CICU and is associated with reduced discharge to healthcare facility and in-hospital mortality.
