RESUMEN
IMPORTANCE: The mechanisms underlying the association between chronic stress and higher mortality among individuals with cancer remain incompletely understood. OBJECTIVE: To test the hypotheses that among individuals with active head and neck cancer, that higher stress-associated neural activity (ie. metabolic amygdalar activity [AmygA]) at cancer staging associates with survival. DESIGN: Retrospective cohort study. SETTING: Academic Medical Center (Massachusetts General Hospital, Boston). PARTICIPANTS: 240 patients with head and neck cancer (HNCA) who underwent 18F-FDG-PET/CT imaging as part of initial cancer staging. MEASUREMENTS: 18F-FDG uptake in the amygdala was determined by placing circular regions of interest in the right and left amygdalae and measuring the mean tracer accumulation (i.e., standardized uptake value [SUV]) in each region of interest. Amygdalar uptake was corrected for background cerebral activity (mean temporal lobe SUV). RESULTS: Among individuals with HNCA (age 59±13 years; 30% female), 67 died over a median follow-up period of 3 years (IQR: 1.7-5.1). AmygA associated with heightened bone marrow activity, leukocytosis, and C-reactive protein (P<0.05 each). In adjusted and unadjusted analyses, AmygA associated with subsequent mortality (HR [95% CI]: 1.35, [1.07-1.70], P = 0.009); the association persisted in stratified subset analyses restricted to patients with advanced cancer stage (P<0.001). Individuals within the highest tertile of AmygA experienced a 2-fold higher mortality rate compared to others (P = 0.01). The median progression-free survival was 25 months in patients with higher AmygA (upper tertile) as compared with 36.5 months in other individuals (HR for progression or death [95%CI], 1.83 [1.24-2.68], P = 0.001). CONCLUSIONS AND RELEVANCE: AmygA, quantified on routine 18F-FDG-PET/CT images obtained at cancer staging, independently and robustly predicts mortality and cancer progression among patients with HNCA. Future studies should test whether strategies that attenuate AmygA (or its downstream biological consequences) may improve cancer survival.

BACKGROUND: There is a need for improved methods for detection and risk stratification of myocarditis associated with immune checkpoint inhibitors (ICIs). Global longitudinal strain (GLS) is a sensitive marker of cardiac toxicity among patients receiving standard chemotherapy. There are no data on the use of GLS in ICI myocarditis. OBJECTIVES: This study sought to evaluate the role of GLS and assess its association with cardiac events among patients with ICI myocarditis. METHODS: This study retrospectively compared echocardiographic GLS by speckle tracking at presentation with ICI myocarditis (cases, n = 101) to that from patients receiving an ICI who did not develop myocarditis (control subjects, n = 92). Where available, GLS was also measured pre-ICI in both groups. Major adverse cardiac events (MACE) were defined as a composite of cardiogenic shock, arrest, complete heart block, and cardiac death. RESULTS: Cases and control subjects were similar in age, sex, and cancer type. At presentation with myocarditis, 61 cases (60%) had a normal ejection fraction (EF). Pre-ICI, GLS was similar between cases and control subjects (20.3 ± 2.6% vs. 20.6 ± 2.0%; p = 0.60). There was no change in GLS among control subjects on an ICI without myocarditis (pre-ICI vs. on ICI, 20.6 ± 2.0% vs. 20.5 ± 1.9%; p = 0.41); in contrast, among cases, GLS decreased to 14.1 ± 2.8% (p < 0.001). The GLS at presentation with myocarditis was lower among cases presenting with either a reduced (12.3 ± 2.7%) or preserved EF (15.3 ± 2.0%; p < 0.001). Over a median follow-up of 162 days, 51 (51%) experienced MACE. The risk of MACE was higher with a lower GLS among patients with either a reduced or preserved EF. After adjustment for EF, each percent reduction in GLS was associated with a 1.5-fold increase in MACE among patients with a reduced EF (hazard ratio: 1.5; 95% confidence interval: 1.2 to 1.8) and a 4.4-fold increase with a preserved EF (hazard ratio: 4.4; 95% confidence interval: 2.4 to 7.8). CONCLUSIONS: GLS decreases with ICI myocarditis and, compared with control subjects, was lower among cases presenting with either a preserved or reduced EF. Lower GLS was strongly associated with MACE in ICI myocarditis presenting with either a preserved or reduced EF.

Human immunodeficiency virus (HIV) imparts increased heart failure risk to women. Among women with HIV (WHIV), immune pathways relating to heart failure precursors may intimate targets for heart failure prevention strategies. Twenty asymptomatic, antiretroviral-treated WHIV and 14 non-HIV-infected women matched on age and body mass index underwent cardiac magnetic resonance imaging and immune phenotyping. WHIV (vs non-HIV-infected women) exhibited increased myocardial fibrosis (extracellular volume fraction, 0.34 ± 0.06 vs 0.29 ± 0.04; P = .002), reduced diastolic function (diastolic strain rate, 1.10 ± 0.23 s-1 vs 1.39 ± 0.27 s-1; P = .003), and heightened systemic monocyte activation. Among WHIV, soluble CD163 levels correlated with myocardial fibrosis (r = 0.53; P = .02), while circulating inflammatory CD14+CD16+ monocyte CCR2 expression related directly to myocardial fibrosis (r = 0.48; P = .04) and inversely to diastolic function (r = -0.49; P = .03). Clinical Trials Registration. NCT02874703.

BACKGROUND: Among persons living with human immunodeficiency virus (PHIV), incident heart failure (HF) rates are increased and outcomes are worse; however, the role of amino-terminal pro-B-type natriuretic peptide (NT-proBNP) concentrations among PHIV with HF has not been characterized. METHODS: Patients were derived from a registry of those hospitalized with HF at an academic center in a calender year. We compared the NT-proBNP concentrations and the changes in NT-proBNP levels between PHIV with HF and uninfected controls with HF. RESULTS: Among 2578 patients with HF, there were 434 PHIV; 90% were prescribed antiretroviral therapy and 62% were virally suppressed. As compared to controls, PHIV had higher admission (3822 [IQR, 2413-7784] pg/ml vs 5546 [IQR, 3257-8792] pg/ml, respectively; P < .001), higher discharge (1922 [IQR, 1045-4652] pg/ml vs 3372 [IQR, 1553-5452] pg/ml, respectively; P < .001), and lower admission-to-discharge changes in NT-proBNP levels (32 vs 48%, respectively; P = .007). Similar findings were noted after stratifying based on left ventricular ejection fraction (LVEF). In a multivariate analysis, cocaine use, a lower LVEF, a higher NYHA class, a higher viral load (VL), and a lower CD4 count were associated with higher NT-proBNP concentrations. In follow-up, among PHIV, a higher admission NT-proBNP concentration was associated with increased cardiovascular mortality (first tertile, 11.5; second tertile, 20; third tertile, 44%; P < .001). Among PHIV, each doubling of NT-proBNP was associated with a 19% increased risk of death. However, among patients living without HIV, each doubling was associated with a 27% increased risk; this difference was attenuated among PHIV with lower VLs and higher CD4 counts. CONCLUSIONS: PHIV with HF had higher admission and discharge NT-proBNP levels, and less change in NT-proBNP concentrations. Among PHIV, VLs and CD4 counts were associated with NT-proBNP concentrations; in follow-up, higher NT-proBNP levels among PHIV were associated with cardiovascular mortality.

BACKGROUND: Chimeric antigen receptors redirect T cells (CAR-T) to target cancer cells. There are limited data characterizing cardiac toxicity and cardiovascular (CV) events among adults treated with CAR-T. OBJECTIVES: The purpose of this study was to evaluate the possible cardiac toxicities of CAR-T. METHODS: The registry included 137 patients who received CAR-T. Covariates included the occurrence and grade of cytokine release syndrome (CRS) and the administration of tocilizumab for CRS. Cardiac toxicity was defined as a decrease in the left ventricular ejection fraction or an increase in serum troponin. Cardiovascular events were a composite of arrhythmias, decompensated heart failure, and CV death. RESULTS: The median age was 62 years (interquartile range [IQR]: 54 to 70 years), 67% were male, 88% had lymphoma, and 8% had myeloma. Approximately 50% were treated with commercial CAR-T (Yescarta or Kymriah), and the remainder received noncommercial products. CRS, occurring a median of 5 days (IQR: 2 to 7 days) after CAR-T, occurred in 59%, and 39% were grade ≥2. Tocilizumab was administered to 56 patients (41%) with CRS, at a median of 27 h (IQR: 16 to 48 h) after onset. An elevated troponin occurred in 29 of 53 tested patients (54%), and a decreased left ventricular ejection fraction in 8 of 29 (28%); each occurred only in patients with grade ≥2 CRS. There were 17 CV events (12%, 6 CV deaths, 6 decompensated heart failure, and 5 arrhythmias; median time to event of 21 days), all occurred with grade ≥2 CRS (31% patients with grade ≥2 CRS), and 95% of events occurred after an elevated troponin. The duration between CRS onset and tocilizumab administration was associated with CV events, where the risk increased 1.7-fold with each 12-h delay to tocilizumab. CONCLUSIONS: Among adults, cardiac injury and CV events are common post-CAR-T. There was a graded relationship among CRS, elevated troponin, and CV events, and a shorter time from CRS onset to tocilizumab was associated with a lower rate of CV events.

OBJECTIVES: The aim of this study was to determine the incidence of sudden cardiac death (SCD) among persons living with human immunodeficiency virus infection (PHIV) with heart failure (HF), who were hospitalized for HF, and the risk factors associated with it. BACKGROUND: HF is associated with an increased risk for SCD. PHIV are at heightened risk for HF. METHODS: This was a retrospective study of 2,578 patients hospitalized with HF from a single academic center, of whom 344 were PHIV. The outcome of interest was SCD. Subgroup analyses were performed by strata of viral load (VL) and left ventricular ejection fraction (LVEF) <35%, 35% to 49%, and ≥50%. RESULTS: Of 2,578 patients with HF, 2,149 (86%) did not have implantable cardioverter-defibrillators; of these, there were 344 PHIV and 1,805 uninfected control subjects. Among PHIV with HF, 313 (91%) were prescribed antiretroviral therapy and 64% were virally suppressed. There were 191 SCDs over a median follow-up period of 19 months. Compared with control subjects, PHIV had a 3-fold increase in SCD (21.0% vs. 6.4%; adjusted odds ratio: 3.0; 95% confidence interval: 1.78 to 4.24). Among PHIV, cocaine use, lower LVEF, absence of beta-blocker prescription, and VL were predictors of SCD. The SCD rate among PHIV with undetectable VL was similar to the rate among uninfected subjects. Similar findings were observed by LVEF strata. Among PHIV with HF without conventional indications for an implantable cardioverter-defibrillator, the rate of SCD was 10% per year. CONCLUSIONS: PHIV hospitalized with HF are at a markedly increased risk for SCD. SCD risk was increased in patients with lower LVEFs, lower CD4 counts, and higher VL.

OBJECTIVES: This study sought to assess the safety of carvedilol therapy among heart failure (HF) patients with a cocaine-use disorder (CUD). BACKGROUND: Although carvedilol therapy is recommended among certain patients with HF, the safety and efficacy of carvedilol among HF patients with a CUD is unknown. METHODS: This was a single-center study of hospitalized patients with HF. Cocaine use was self-reported or defined as having a positive urine toxicology. Patients were divided by carvedilol prescription. Subgroup analyses were performed by strata of ejection fraction (EF) ≤40%, 41% to 49%, or ≥50%. Major adverse cardiovascular events (MACE) were defined as cardiovascular mortality and 30-day HF readmission. RESULTS: From a cohort of 2,578 patients hospitalized with HF in 2011, 503 patients with a CUD were identified, among whom 404 (80%) were prescribed carvedilol, and 99 (20%) were not. Both groups had similar characteristics; however, those prescribed carvedilol had a lower LVEF, heart rate, and N-terminal pro-B-type natriuretic peptide concentrations at admission and on discharge, and more coronary artery disease. Over a median follow-up of 19 months, there were 169 MACEs. The MACE rates were similar between the carvedilol and the non-carvedilol groups (32% vs. 38%, respectively; p = 0.16) and between those with a preserved EF (30% vs. 33%, respectively; p = 0.48) and were lower in patients with a reduced EF taking carvedilol (34% vs. 58%, respectively; p = 0.02). In a multivariate model, carvedilol therapy was associated with lower MACE among patients with HF with a CUD (hazard ratio: 0.67; 95% confidence interval; 0.481 to 0.863). CONCLUSIONS: Our findings suggest that carvedilol therapy is safe for patients with HF with a CUD and may be effective among those with a reduced EF.

CONTEXT: Women with HIV (WHIV) on anti-retroviral therapy (ART) are living longer but facing heightened vulnerability to heart failure. OBJECTIVE: We investigated metabolic/hormonal/immune parameters relating to diastolic dysfunction-a precursor to heart failure-among WHIV without known cardiovascular disease (CVD). DESIGN AND OUTCOME MEASURES: Nineteen ART-treated WHIV and 11 non-HIV-infected women without known CVD enrolled and successfully completed relevant study procedures [cardiac magnetic resonance spectroscopy (MRS) and cardiac MRI]. Groups were matched on age and body mass index. Primary outcome measures included intramyocardial triglyceride content (cardiac MRS) and diastolic function (cardiac MRI). Relationships between intramyocardial triglyceride content and clinical parameters were also assessed. RESULTS: Among WHIV (vs non-HIV-infected women), intramyocardial triglyceride content was threefold higher [1.2 (0.4, 3.1) vs 0.4 (0.1, 0.5)%, P = 0.01], and diastolic function was reduced (left atrial passive ejection fraction: 27.2 ± 9.6 vs 35.9 ± 6.4%, P = 0.007). There was a strong inverse relationship between intramyocardial triglyceride content and diastolic function (ρ = -0.62, P = 0.004). Among the whole group, intramyocardial triglyceride content did not relate to chronologic age but did increase across the reproductive aging spectrum (P = 0.02). HIV status and reproductive aging status remained independent predictors of intramyocardial triglyceride content after adjusting for relevant cardiometabolic parameters (overall model R2 = 0.56, P = 0.003; HIV status P = 0.01, reproductive aging status P = 0.02). CONCLUSIONS: For asymptomatic WHIV, increased intramyocardial triglyceride content is associated with diastolic dysfunction. Moreover, relationships between intramyocardial triglyceride accumulation and women's reproductive aging are noted.

BACKGROUND: Persons living with HIV (PLHIV) have an increased risk of heart failure (HF). However, little is known about outcomes among PLHIV with HF. The study aim was to compare HF outcomes among PLHIV with HF versus individuals without HIV with HF. METHODS: Our cohort included 2,308 individuals admitted with decompensated HF. We compared baseline characteristics, 30-day HF readmission, and cardiovascular (CV) and all-cause mortality. Within PLHIV, we assessed outcomes stratified between CD4 count and viral load (VL), and tested the association between traditional and HIV-specific parameters with 30-day HF readmission. RESULTS: There were 374 (16%) PLHIV with HF. Among PLHIV, 92% were on antiretroviral therapy and 63% had a VL <200 copies/mL. Groups were similar with respect to age, sex, race/ethnicity, and CV risk factors. In follow-up, PLHIV had increased 30-day HF readmission (49% vs 32%) and CV (26% vs 13.5%) and all-cause mortality rates (38% vs 22%). Among PLHIV, cocaine use, HIV-specific parameters (CD4, VL), and coronary artery disease were predictors of 30-day HF readmission. Specifically, among PLHIV, those with detectable VL had higher 30-day HF readmission and CV mortality, whereas PLHIV with undetectable VL had a similar 30-day HF readmission rate and CV mortality to uninfected controls with HF. Similar outcomes were observed across strata of left ventricular ejection fraction and by CD4. CONCLUSIONS: PLHIV with a low CD4 count or detectable VL have an increased 30-day HF readmission rate as well as increased CV and all-cause mortality. In contrast, PLHIV with a higher CD4 count and undetectable VL have similar HF outcomes to uninfected controls.

Background People living with HIV ( PHIV ) are at an increased risk for sudden cardiac death, and implantable cardioverter-defibrillators ( ICDs ) prevent SCD . There are no data on the incidence, predictors, and effects of ICD therapies among PHIV . Methods and Results We compared ICD discharge rates between 59 PHIV and 267 uninfected controls. For PHIV , we tested the association of traditional cardiovascular risk factors and HIV -specific parameters with an ICD discharge and then tested whether an ICD discharge among PHIV was associated with cardiovascular mortality or an admission for heart failure. The indication for ICD insertion was similar among groups. Compared with controls, PHIV with an ICD were more likely to have coronary artery disease and to use cocaine. In follow-up, PHIV had a higher ICD discharge rate (39% versus 20%; P=0.001; median follow-up period, 19 months). Among PHIV , cocaine use, coronary artery disease, QRS duration, and higher New York Heart Association class were associated with an ICD discharge. An ICD discharge had a prognostic effect, with a subsequent 1.7-fold increase in heart failure admission and a 2-fold increase in cardiovascular mortality, an effect consistent across racial/ethnic and sex categories. Conclusions ICD discharge rates are higher among PHIV compared with uninfected controls. Among PHIV , cocaine use and New York Heart Association class are associated with increased ICD discharge, and an ICD discharge is associated with a subsequent increase in admission for heart failure and cardiovascular mortality.
