RESUMEN

BACKGROUND: National prevalence rates for obesity and heart failure (HF) have been steadily increasing, which predisposes patients to higher morbidity and mortality rates. OBJECTIVES: The purpose of this study was to evaluate the prevalence of HF stages in hospitalized patients according to their body mass index (BMI). SETTING: Academic institution. METHODS: National Inpatient Sample data from 2016 to 2018 were examined to identify patients with obesity, HF (presence or absence of advanced HF [AHF]), and cardiogenic shock (CS). The proportion of hospital admissions was determined for each category on the basis of the presence of AHF with/without CS. A comparative analysis was performed between patients with and without AHF, and multivariate logistic regression analysis was performed for the event of AHF. The same analyses were performed for the event of CS. RESULTS: A total of 3,354,970 hospital admissions were identified. The prevalence of hospital admissions with a diagnosis of AHF and class III obesity and a diagnosis of CS and class III obesity was 21% and .5%, respectively. The prevalence of AHF and other classes of BMI and CS and other classes of BMI was 17% and .5%, respectively. The univariate analysis showed that there were significant variations in 10 factors between hospital admissions with/without the diagnosis of both AHF and CS. Statistical analyses indicated the following findings: Hospitalized patients in higher obesity groups are more likely to have AHF, and they are less likely to have CS compared with those with a BMI of ≤29.9. CONCLUSIONS: This study revealed that the prevalence of AHF was significantly higher in hospitalized patients with class III obesity. These findings have implications for clinical management, and it can be inferred that these patients are less likely to receive advanced cardiac replacement therapies and might benefit from innovative approaches to address severe dual morbidity.

RESUMEN

BACKGROUND: In patients with transthyretin cardiac amyloidosis (ATTR-CA), renal dysfunction is a poor prognostic indicator. Limited data are available on variables that portend worsening renal function (wRF) among ATTR-CA patients. OBJECTIVES: This study assesses which characteristics place patients at higher risk for the development of wRF (defined as a drop of ≥10% in glomerular filtration rate [GFR]) within the first year following diagnosis of ATTR-CA. METHODS: We included patients with ATTR-CA (n = 134) evaluated between 2/2016 and 12/2022 and followed for up to 1 year at our amyloid clinic. Patients were stratified into two groups: a group with maintained renal function (mRF) and a group with wRF and compared using appropriate testing. Significant variables in the univariate analysis were included in the multivariable logistic regression model to determine characteristics associated with wRF. RESULTS: Within a follow-up period of 326 ± 118 days, the median GFR% change measured -6% [-18%, +8]. About 41.8% (n = 56) had wRF, while the remainder had mRF. In addition, in patients with no prior history of chronic kidney disease (CKD), 25.5% developed de novo CKD. On multivariable logistic regression, only New York Heart Association (NYHA) class ≥III (odds ratio [OR]: 3.9, 95% confidence interval [CI]: [1.6-9.3]), history of ischemic heart disease (IHD) (OR: 0.3, 95% CI: [0.1-0.7]), and not receiving SGLT-2i (OR: 0.1, 95% CI: [0.02-0.5]) were significant predictors of wRF. CONCLUSION: Our study demonstrated that the development of de novo renal dysfunction or wRF is common following the diagnosis of ATTR-CA. Additionally, we identified worse NYHA class and no prior history of IHD as significant predictors associated with developing wRF, while receiving SGLT-2i therapy appeared to be protective in this population.

RESUMEN

BACKGROUND: Molecular testing with gene-expression profiling (GEP) and donor-derived cell-free DNA (dd-cfDNA) is increasingly used in the surveillance for acute cellular rejection (ACR) after heart transplant. However, the performance of dual testing over each test individually has not been established. Further, the impact of dual noninvasive surveillance on clinical decision-making has not been widely investigated. METHODS: We evaluated 2,077 subjects from the Surveillance HeartCare Outcomes Registry registry who were enrolled between 2018 and 2021 and had verified biopsy data and were categorized as dual negative, GEP positive/dd-cfDNA negative, GEP negative/dd-cfDNA positive, or dual positive. The incidence of ACR and follow-up testing rates for each group were evaluated. Positive likelihood ratios (LRs+) were calculated, and biopsy rates over time were analyzed. RESULTS: The incidence of ACR was 1.5% for dual negative, 1.9% for GEP positive/dd-cfDNA negative, 4.3% for GEP negative/dd-cfDNA positive, and 9.2% for dual-positive groups. Follow-up biopsies were performed after 8.8% for dual negative, 14.2% for GEP positive/dd-cfDNA negative, 22.8% for GEP negative/dd-cfDNA positive, and 35.4% for dual-positive results. The LR+ for ACR was 1.37, 2.91, and 3.90 for GEP positive, dd-cfDNA positive, and dual-positive testing, respectively. From 2018 to 2021, biopsies performed between 2 and 12-months post-transplant declined from 5.9 to 5.3 biopsies/patient, and second-year biopsy rates declined from 1.5 to 0.9 biopsies/patient. At 2 years, survival was 94.9%, and only 2.7% had graft dysfunction. CONCLUSIONS: Dual molecular testing demonstrated improved performance for ACR surveillance compared to single molecular testing. The use of dual noninvasive testing was associated with lower biopsy rates over time, excellent survival, and low incidence of graft dysfunction.

RESUMEN

INTRODUCTION: Some studies have shown increased incidence of Primary Graft Dysfunction (PGD) after heart and lung procurement for heart transplant recipients. There have been limited investigations of the impact of lung procurement on heart procurement and the potential effects of the exposure to the type of lung preservation solution, the volume of the lung preservation solution and adequacy of decompression of the heart during heart and lung procurement and the impact on heart transplant outcomes. METHODS: Adult heart transplant recipients in the UNOS database recorded from January 1, 2000 to June 30, 2022 formed the study cohort. Any heart that was procured with a lung team that utilized Perfadex preservation solution (XVIVO, Gothenburg, Sweden) was classified as exposed to Perfadex and otherwise classified as not exposed to Perfadex. Lung procurements performed with a preservation solution other than Perfadex or unknown were excluded (n = 2486). Simple comparisons were made with t-tests or chi-squared tests. Logistic regression models were used to predict 30 day and 1 year survival. Accelerated failure time models were employed to analyze time to death and time to rejection. RESULTS: The cohort consisted of 34 192 heart transplants, of which 21 928 donors were not exposed to Perfadex (64.1%). There were statistically, but not clinically, significant differences in donor characteristics for these groups including in donor age (33.34 ± 11.01 not exposed vs. 30.70 ± 10.69 exposed; p < .001), diabetic donor (4% not exposed vs. 3% exposed; p = .004), and ischemic time (3.28 ± 1.09 h not exposed vs. 3.24 ± 1.05 h exposed; p = .002). In adjusted models, for all included donors, Perfadex exposure was associated with increased short term mortality, but no long term difference (1 year mortality OR 1.10, p = .014). CONCLUSION: Perfadex exposure was associated with increased short-term mortality for heart transplant recipients. Mechanistic investigation is warranted.

RESUMEN

The potential for increased rates of morbidity of SARS-CoV-2 within immunocompromised populations has been of concern since the pandemic's onset. Transplant providers and patients can face particularly challenging situations, in the current settings as data continues to emerge for the prevention and treatment of the immunocompromised subpopulation. This case report details a patient 9-months post orthotopic heart transplant that developed SARS-CoV-2 infection despite two prior doses of the Pfizer-BioNtech COVID-19 vaccine, and had successful rescue from refractory hypoxemia with veno-venous extracorporeal membrane oxygenation (VV ECLS).

RESUMEN

In recent years, there have been significant advancements in the understanding, risk-stratification, and treatment of cardiogenic shock (CS). Despite improved pharmacologic and device-based therapies for CS, short-term mortality remains as high as 50%. Most recent efforts in research have focused on CS related to acute myocardial infarction, even though heart failure related CS (HF-CS) accounts for >50% of CS cases. There is a paucity of high-quality evidence to support standardized clinical practices in approach to HF-CS. In addition, there is an unmet need to identify disease-specific diagnostic and risk-stratification strategies upon admission, which might ultimately guide the choice of therapies, and thereby improve outcomes and optimize resource allocation. The heterogeneity in defining CS, patient phenotypes, treatment goals and therapies has resulted in difficulty comparing published reports and standardized treatment algorithms. An International Society for Heart and Lung Transplantation (ISHLT) consensus conference was organized to better define, diagnose, and manage HF-CS. There were 54 participants (advanced heart failure and interventional cardiologists, cardiothoracic surgeons, critical care cardiologists, intensivists, pharmacists, and allied health professionals), with vast clinical and published experience in CS, representing 42 centers worldwide. State-of-the-art HF-CS presentations occurred with subsequent breakout sessions planned in an attempt to reach consensus on various issues, including but not limited to models of CS care delivery, patient presentations in HF-CS, and strategies in HF-CS management. This consensus report summarizes the contemporary literature review on HF-CS presented in the first half of the conference (part 1), while the accompanying document (part 2) covers the breakout sessions where the previously agreed upon clinical issues were discussed with an aim to get to a consensus.

RESUMEN

The last decade has brought tremendous interest in the problem of cardiogenic shock. However, the mortality rate of this syndrome approaches 50%, and other than prompt myocardial revascularization, there have been no treatments proven to improve the survival of these patients. The bulk of studies have been in patients with acute myocardial infarction, and there is little evidence to guide the clinician in those patients with heart failure cardiogenic shock (HF-CS). An International Society for Heart and Lung Transplant consensus conference was organized to better define, diagnose, and manage HF-CS. There were 54 participants (advanced heart failure and interventional cardiologists, cardiothoracic surgeons, critical care cardiologists, intensivists, pharmacists, and allied health professionals) with vast clinical and published experience in CS, representing 42 centers worldwide. This consensus report summarizes the results of a premeeting survey answered by participants and the breakout sessions where predefined clinical issues were discussed to achieve consensus in the absence of robust data. Key issues discussed include systems for CS management, including the "hub-and-spoke" model vs a tier-based network, minimum levels of data to communicate when considering transfer, disciplines that should be involved in a "shock team," goals for mechanical circulatory support device selection, and optimal flow on such devices. Overall, the document provides expert consensus on some important issues facing practitioners managing HF-CS. It is hoped that this will clarify areas where consensus has been reached and stimulate future research and registries to provide insight regarding other crucial knowledge gaps.

RESUMEN

BACKGROUND: One-time assessment of the Society for Cardiovascular Angiography and Interventions (SCAI) shock classification robustly predicts mortality in the cardiac intensive care unit (CICU). We sought to determine whether serial SCAI shock classification could improve risk stratification. METHODS AND RESULTS: Unique admissions to a single academic level 1 CICU from 2015 to 2018 were included in this retrospective cohort study. Electronic health record data were used to assign the SCAI shock stage during 4-hour blocks of the first 24 hours of CICU admission. Shock was defined as hypoperfusion (SCAI shock stage C, D, or E). In-hospital death was evaluated using logistic regression. Among 2918 unique CICU patients, 1537 (52.7%) met criteria for shock during ≥1 block, and 266 (9.1%) died in the hospital. The SCAI shock stage on admission was: A, 37.6%; B, 31.5%; C, 25.9%; D, 1.8%; and E, 3.3%. Patients who met SCAI criteria for shock on admission (first 4 hours) and those with worsening SCAI shock stage after admission were at higher risk for in-hospital death. Each higher admission (adjusted odds ratio, 1.36 [95% CI, 1.18-1.56]; area under the receiver operating characteristic curve, 0.70), maximum (adjusted odds ratio, 1.59 [95% CI, 1.37-1.85]; area under the receiver operating characteristic curve, 0.73) and mean (adjusted odds ratio, 2.42 [95% CI, 1.99-2.95]; area under the receiver operating characteristic curve, 0.78) SCAI shock stage was incrementally associated with a higher in-hospital mortality rate. Discrimination was highest for the mean SCAI shock stage (P<0.05). Each additional 4-hour block meeting SCAI criteria for shock predicted a higher mortality rate (adjusted odds ratio, 1.15 [95% CI, 1.07-1.24]). CONCLUSIONS: Dynamic assessment of shock using serial SCAI shock classification assignment can improve mortality risk stratification in CICU patients by quantifying the magnitude and duration of shock.

RESUMEN

BACKGROUND: Cardiorenal syndrome (CRS) complicates 33% of acute decompensated heart failure (ADHF) admissions, and patients with persistent congestion at discharge have high 30-day event rates. OBJECTIVES: The purpose of this study was to evaluate a novel catheter-deployed intra-aortic entrainment pump (IAEP) in patients with ADHF with CRS and persistent congestion. METHODS: A multicenter (n = 14), nonrandomized, single-arm, safety and feasibility study of IAEP therapy was conducted. Within patient changes (post-pre IAEP therapy) in fluid loss, hemodynamics, patient-reported dyspnea, and serum biomarkers were assessed using Wilcoxon signed-rank testing. RESULTS: Of 21 enrolled patients, 18 received Aortix therapy. Mean ± SD patient age was 60.3 ± 7.9 years. The median left ventricular ejection fraction was 22.5% (25th-75th percentile: 10.0%-53.5%); 27.8% had a left ventricular ejection fraction ≥50%. Pre-therapy, patients received 8.7 ± 4.1 days of loop diuretic agents and 44% were on inotropes. Pump therapy averaged 4.6 ± 1.6 days, yielding net fluid losses of 10.7 ± 6.5 L (P < 0.001) and significant (P < 0.01) reductions in central venous pressure (change from baseline: -8.5 mm Hg [25th-75th percentile: -3.5 to -10.0 mm Hg]), pulmonary capillary wedge pressure (-11.0 mm Hg [25th-75th percentile: -5.0 to -14.0 mm Hg]), and serum creatinine (-0.2 mg/dL [25th-75th percentile: -0.1 to -0.5 mg/dL]) with improved estimated glomerular filtration rate (+5.0 mL/min/1.73 m2 [25th-75th percentile: 2.0-9.0 mL/min/1.73 m2]) and patient-reported dyspnea score (+16 [25th-75th percentile: 3-37]). Dyspnea scores, natriuretic peptides, and renal function improvements persisted through 30 days. CONCLUSIONS: This pilot study of patients with ADHF, persistent congestion, and worsening renal function due to CRS supports the potential for safely achieving decongestion using IAEP therapy. These initial promising results provide the basis for future randomized clinical trials of this novel pump.

RESUMEN

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) use for circulatory support in cardiogenic shock results in increased left ventricular (LV) afterload. The use of concomitant Impella or intra-aortic balloon pump (IABP) have been proposed as adjunct devices for LV unloading. The authors sought to compare head-to-head efficacy and safety outcomes between the 2 LV unloading strategies. We conducted a search of Medline, EMBASE, and Cochrane databases to identify studies comparing the use of Impella to IABP in patients on VA-ECMO. The primary outcome of interest was in-hospital mortality. The secondary outcomes included transition to durable LV assist devices/cardiac transplantation, stroke, limb ischemia, need for continuous renal replacement therapy, major bleeding, and hemolysis. Pooled risk ratios (RRs) with 95% confidence interval and heterogeneity statistic I2 were calculated using a random-effects model. A total of 7 observational studies with 698 patients were included. Patients on VA-ECMO unloaded with Impella vs IABP had similar risk of short-term all-cause mortality, defined as either 30-day or in-hospital mortality- 60.8% vs 64.9% (RR 0.93 [0.71 to 1.21], I2 = 71%). No significant difference was observed in transition to durable LV assist devices/cardiac transplantation, continuous renal replacement therapy initiation, stroke, or limb ischemia between the 2 strategies. However, the use of VA-ECMO with Impella was associated with increased risk of major bleeding (57.2% vs 39.7%) (RR 1.66 [1.12 to 2.44], I2 = 82%) and hemolysis (31% vs 7%) (RR 4.61 [1.24 to 17.17], I2 = 66%) compared with VA-ECMO, along with IABP. In conclusion, in patients requiring VA-ECMO for circulatory support, the concomitant use of Impella or IABP had comparable short-term mortality. However, Impella use was associated with increased risk of major bleeding and hemolysis.

RESUMEN

BACKGROUND: Cardiac transplantation requires lifelong immunosuppressant medications to prevent rejection. However, some patients may not tolerate multiple immunosuppressants due to adverse effects. At our institution, patients may be converted to monotherapy with tacrolimus if unable to tolerate a combination regimen. This study evaluated the outcomes among patients converted to tacrolimus monotherapy compared with those maintained on combination immunosuppression. METHODS: This single-center, retrospective cohort study included patients who received heart transplants at Sentara Norfolk General Hospital between January 2015 and July 2021. Patients were classified as receiving tacrolimus monotherapy (Mono) or combination immunosuppression (Combo). The primary outcome was all-cause mortality with key secondary outcomes including incidence of 2R/3R rejection, necessity for renal replacement therapy, and infection. RESULTS: 112 patients were included (Mono = 25, Combo = 87). Median age at transplant was 53.8 years (Mono) and 52.1 years (Combo). The most common reasons for conversion to monotherapy were leukopenia, infection, and gastrointestinal (GI) distress. There was no difference in mortality (0 in Mono, 11 in Combo; p = .09) or percentage of patients with 2R/3R rejection (24% in Mono, 32.2% in Combo; p = .43). No Mono group patients experienced rejection after converting from combination therapy. 24% of Mono group patients resumed at least one additional immunosuppressive medication during the study period. Median time to monotherapy was 9.0 months, with a total median duration on monotherapy of 16.0 months. A median of 3.3 years of follow-up was observed for patients in Mono and 3.4 years in Combo (p = .29). CONCLUSION: Selected patients who do not tolerate combination immunosuppression can be safely transitioned to tacrolimus monotherapy as a means of controlling adverse events without an increased risk of mortality or rejection.

RESUMEN

PURPOSE: There are limited data examining the impact of both donor and recipient race on outcomes following orthotopic heart transplant (OHT). The purpose of this study was to evaluate the relationship between donor and recipient race and OHT outcomes. METHODS: The United Network for Organ Sharing (UNOS) database was retrospectively reviewed from January 2000 to March 2018 for donor hearts. A comparison was conducted based on donor and recipient race (White, Black, Hispanic, Other/Unknown). Races for which there were limited numbers were excluded from the analysis (Asian, n = 1292; American Indian, n = 132; Pacific Islander, n = 132, Multiple ethnicities, n = 225). The primary endpoint was survival at 30 days, 1 year survival, and post-transplant rejection. Logistic and Cox models were used to quantify survival endpoints. RESULTS: A total of 41 841 OHT were included. Of the recipients, 29 894 (71%) were White, 8475 (20%) were Black, and 3472 (8%) were Hispanic. Of the donors 27 783 (66%) were White, 6277 (15%) were Black, 6576 (16%) were Hispanic, and 1205 (3%) were Unknown/Other race. In a comparison of recipient demographics, White recipients were older (54.09 ± 12.21 years) compared to Black (49.44 ± 12.83 years) and Hispanic (49.97 ± 13.27 years) recipients. All other differences between groups were not clinically significant. Black recipients were more likely to receive a heart with an "urgent" status (probability .80) compared to White (.73) and Hispanic (.75) recipients (p < .001). Hispanic recipients were more likely to receive a transplant when listed as "non-urgent" (Probability .47) compared to White (.37) and Black (.30) recipients (p < .001). In terms of outcomes, compared to White recipients, Hispanic patients experienced a decreased 30-day survival (OR 1.27; p = .011) and 1-year survival (OR 1.17; p = .016). In comparing Donor/Recipient combinations compared to a White Donor/White Recipient combination, overall survival was decreased in White donor/African American recipient (HR 1.36; p < .001), African American donor/African American recipient (HR 1.41; p < .001) and Hispanic donor/African American recipient (HR 1.30; p < .001) combinations (Table 1). CONCLUSIONS: African American and Hispanic recipients have decreased survival compared to White recipients after heart transplant. The African American donor does not decrease survival. Racial differences still exist in donor and recipient characteristics and recipient outcomes after OHT. Increasing the donor pool for all races and ethnicities would potentially benefit all recipients. Continued study is warranted in order to minimize these differences among recipients and identify factors that could be contributing to decreased survival, in order to optimize outcomes for African American and Hispanic recipients post-transplant and eliminate disparities.

RESUMEN

PURPOSE OF REVIEW: Cardiogenic shock (CS) has been recognized for >50 years, most commonly in the setting of myocardial infarction. This review covers recent advances in the definitions, epidemiology and severity assessment of cardiogenic shock. RECENT FINDINGS: In this review, the authors discuss the evolving definitions of cardiogenic shock, detailing the early approaches as well as more contemporary ideas. The epidemiology of CS is reviewed and then granular detail on the assessment of shock severity is provided including the role of lactate measurement and invasive hemodynamic assessment. The development of the Society for Cardiac Angiography and Intervention (SCAI) consensus statement on Classification of Cardiogenic Shock is reviewed by the principal authors. The revised SCAI Shock document is reviewed as well and the future directions for assessment of shock along with clinical applications are reviewed. SUMMARY: Cardiogenic shock mortality has not changed in a significant way in many years. Recent advances such as more granular assessment of shock severity have the potential to improve outcomes by allowing research to separate the patient groups which may respond differently to various therapies.
