RESUMO
Contemporary anticancer therapies frequently have different efficacy and side effects in men and women. Yet, whether women are well-represented in pivotal trials supporting contemporary anticancer drugs is unknown. Leveraging the Drugs@FDA database, clinicaltrials.gov, MEDLINE, and publicly available FDA-drug-reviews, we identified all pivotal (phase II and III) non-sex specific trials supporting FDA-approval of anticancer drugs (1998-2018). Observed-enrollment-rates were compared to expected-population-rates derived from concurrent US-National-Cancer-Institute's Surveillance-Epidemiology-and-End-Results (SEER) reported rates and US-Census databases. Primary outcome was the proportional representation of women across trials, evaluated by a participation-to-prevalence ratio (PPR), according to cancer type. Secondary outcome was the report of any sex-specific analysis of efficacy and/or safety, irrespective of treatment-arm. Overall, there were 148 trials, enrolling 60,216 participants (60.5 ± 4.0 years, 40.7% female, 79.1% biologic, targeted, or immune-based therapies) evaluating 99 drugs. Sex was reported in 146 (98.6%) trials, wherein 40.7% (24,538) were women, compared to 59.3% (35,678) men (p < .01). Altogether, women were under-represented in 66.9% trials compared to the proportional incidence of cancers by respective disease type; weight-average PPR of 0.91 (relative difference: -9.1%, p < .01). Women were most under-represented in gastric (PPR = 0.63), liver (PPR = 0.71), and lung (PPR = .81) cancer trials. Sex-based safety data was reported in 4.0% trials. There was no association between adequate female enrollment and drug efficacy (HR: 0.616 vs. 0.613, p = .96). Over time, there was no difference in the percentage of women recruited into clinical trials. Among pivotal clinical trials supporting contemporary FDA-approved cancer drugs, women were frequently under-represented and sex-specific-efficacy and safety-outcomes were commonly not reported.
RESUMO
Importance: Barriers to heart transplant must be overcome prior to listing. It is unclear why Black men and women remain less likely to receive a heart transplant after listing than White men and women. Objective: To evaluate whether race or gender of a heart transplant candidate (ie, patient on the transplant waiting list) is associated with the probability of a donor heart being accepted by the transplant center team with each offer. Design, Setting, and Participants: This cohort study used the United Network for Organ Sharing datasets to identify organ acceptance with each offer for US non-Hispanic Black (hereafter, Black) and non-Hispanic White (hereafter, White) adults listed for heart transplant from October 18, 2018, through March 31, 2023. Exposures: Black or White race and gender (men, women) of a heart transplant candidate. Main Outcomes and Measures: The main outcome was heart offer acceptance by the transplant center team. The number of offers to acceptance was assessed using discrete time-to-event analyses, nonparametrically (stratified by race and gender) and parametrically. The hazard probability of offer acceptance for each offer was modeled using generalized linear mixed models adjusted for candidate-, donor-, and offer-level variables. Results: Among 159â¯177 heart offers with 13â¯760 donors, there were 14â¯890 candidates listed for heart transplant; 30.9% were Black, 69.1% were White, 73.6% were men, and 26.4% were women. The cumulative incidence of offer acceptance was highest for White women followed by Black women, White men, and Black men (P < .001). Odds of acceptance were less for Black candidates than for White candidates for the first offer (odds ratio [OR], 0.76; 95% CI, 0.69-0.84) through the 16th offer. Odds of acceptance were higher for women than for men for the first offer (OR, 1.53; 95% CI, 1.39-1.68) through the sixth offer and were lower for the 10th through 31st offers. Conclusions and Relevance: The cumulative incidence of heart offer acceptance by a transplant center team was consistently lower for Black candidates than for White candidates of the same gender and higher for women than for men. These disparities persisted after adjusting for candidate-, donor-, and offer-level variables, possibly suggesting racial and gender bias in the decision-making process. Further investigation of site-level decision-making may reveal strategies for equitable donor heart acceptance.

BACKGROUND: Durable mechanical circulatory support (MCS) therapy improves survival in patients with advanced heart failure. Knowledge regarding the outcomes experienced by patients with inflammatory cardiomyopathy (CM) who receive durable MCS therapy is limited. METHODS AND RESULTS: We compared patients with inflammatory CM with patients with idiopathic dilated CM enrolled in the STS-INTERMACS registry. Among 19,012 patients, 329 (1.7%) had inflammatory CM and 5978 had idiopathic dilated CM (31.4%). The patients with inflammatory CM were younger, more likely to be White, and women. These patients experienced more preoperative arrhythmias and higher use of temporary MCS. Patients with inflammatory CM had a higher rate of early adverse events (<3 months after device implant), including bleeding, arrhythmias, non-device-related infections, neurologic dysfunction, and respiratory failure. The rate of late adverse events (≥3 months) was similar in the 2 groups. Patients with inflammatory CM had a similar 1-year (80% vs 84%) and 2-year (72% vs 76%, Pâ¯=â¯.15) survival. Myocardial recovery resulting in device explant was more common among patients with inflammatory CM (5.5% vs 2.3%, P < .001). CONCLUSIONS: Patients with inflammatory CM who received durable MCS appear to have a similar survival compared with patients with idiopathic dilated CM despite a higher early adverse event burden. Our findings support the use of durable MCS in an inflammatory CM population.

BACKGROUND: Many patients with American College of Cardiology/American Heart Association Stage D (advanced) heart failure are discharged home on chronic intravenous inotropic support (CIIS) as bridge to surgical therapy or as palliative therapy. This study analyzed the clinical trajectory of patients with advanced heart failure who were on home CIIS. METHODS: We conducted a single-institution, retrospective cohort study of patients on CIIS between 2010 and 2016 (nâ¯=â¯373), stratified by indication for initiation of inotropic support. Study outcomes were time from initiation of CIIS to cessation of therapy, time to death for patients who did not receive surgical therapy and rates of involvement with palliative care. RESULTS: Overall, patients received CIIS therapy for an average of 5.9 months (standard deviation [SD] 7.3). Patients on CIIS as palliative therapy died in an average of 6.2 months (SD 6.6) from the time of initiation of CIIS, and those on CIIS as bridge therapy who did not ultimately receive surgical therapy died after an average of 8.6 months (SD 9.3). Patients who received CIIS as bridge therapy were significantly less likely to receive palliative-care consultation than those on inotropes as palliative therapy, whether or not they underwent surgery. CONCLUSIONS: In this large cohort of patients with advanced HF, patients who on CIIS as palliative therapy survived for 6.2 months, on average, with wide variation among patients. Patients who were on CIIS as bridge therapy but did not ultimately receive surgical therapy received less palliative care despite the high mortality rate in this subgroup.

BACKGROUND: Cardiac sarcoidosis (CS) is an increasingly recognized cause of cardiomyopathy; however, data on immunosuppressive strategies are limited. Treatment with tumor necrosis factor (TNF) alpha inhibitors is not well described; moreover, there may be heart failure-related safety concerns. METHODS: Retrospective multicenter study of patients with CS treated with TNF alpha inhibitors. Baseline characteristics, treatments, and outcomes were adjudicated. RESULTS: Thirty-eight patients with CS (mean age 49.9 years, 42% women, 53% African American) were treated with TNF alpha inhibitor (30 infliximab, 8 adalimumab). Prednisone dose decreased from time of TNF alpha inhibitor initiation (21.7 ± 17.5 mg) to 6 months (10.4 ± 6.1 mg, Pâ¯=â¯.001) and 12 months (7.3 ± 7.3 mg, Pâ¯=â¯.002) after treatment. On pre-TNF alpha inhibitor treatment positron emission tomography with 18-flourodoxyglucose (FDG-PET), 84% of patients had cardiac FDG uptake. After treatment, there was a significant decrease in number of segments involved (3.5 ± 3.8 to 1.0 ± 2.5, Pâ¯=â¯.008) and maximum standardized uptake value (3.59 ± 3.70 to 0.57 ± 1.60, Pâ¯=â¯.0005), with 73% of patients demonstrating complete resolution or improvement of cardiac FDG uptake. The left ventricular ejection fraction remained stable (45.0 ± 16.5% to 47.0 ± 15.0%, Pâ¯=â¯.10). Four patients required inpatient heart failure treatment, and 8 had infections; 2 required treatment cessation. CONCLUSIONS: TNF alpha inhibitor treatment guided by FDG-PET imaging may minimize corticosteroid use and effectively reduce cardiac inflammation without significant adverse effect on cardiac function. However, infections were common, some of which were serious, and therefore patients require close monitoring for both infection and cardiac symptoms.

BACKGROUND: Women differ from men in their left ventricular (LV) structure, function and remodeling with age and diseases. The LV assist device (LVAD) unloads the LV and reversely remodels the heart. We sought to define the effects of sex on longitudinal reverse remodeling after LVAD implantation. METHODS AND RESULTS: Cardiac structure and function were assessed by serial echocardiograms. Mixed effect regression models were constructed to assess the independent contribution of sex to longitudinal changes in cardiac structure and function. A total of 355 consecutive patients with advanced heart failure received continuous flow LVADs between 2006 and 2016. The average age was 56 ± 13 years, 73% were men, and 67% were black. Early (within 3 months) after LVAD implantation, women had a greater reduction in LV dimensions and a greater increase in LV ejection fraction compared with men. These differences were independent of age, body surface area, device type, or ischemic etiology of heart failure. At long-term follow-up, LV dimensions increased slightly over time in women compared with men, but overall, earlier changes were maintained. CONCLUSION: Women had significantly more favorable longitudinal changes in cardiac structure and function in response to LV unloading compared with men. Understanding the cause of sex difference in reverse remodeling after LVAD may help to devise novel therapeutic strategies for women with advanced heart failure.

BACKGROUND: Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEIs-ARBs) improve outcomes in heart failure (HF). Less is known about this association in nursing home (NH) residents. METHODS: Of the 8024 hospitalized HF patients, 542 were NH residents, of whom 250 received ACEIs-ARBs. We assembled a propensity score-matched cohort of 157 pairs of NH residents receiving and not receiving ACEIs-ARBs balanced on 29 baseline characteristics (mean age, 83 years, 74% women, 17% African American), in which we estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for outcomes associated with ACEI-ARB use. We then checked for interaction in a matched cohort of 5130 patients (378 were NH residents) assembled from the 8024 patients. RESULTS: Among 314 matched NH residents, HRs (95% CIs) for 30-day all-cause readmission, HF readmission, and all-cause mortality were 0.78 (0.47-1.28), 0.68 (0.29-1.60), and 1.26 (0.70-2.27), respectively. Respective HRs (95% CIs) at 1 year were 0.76 (0.56-1.02), 0.68 (0.42-1.09), and 1.04 (0.78-1.38). Among 5130 matched patients, ACEI-ARB use was associated with a significantly lower risk of all outcomes at both times, with no significant interactions, except for 1-year mortality, which was only significant in the non-NH subgroup (P for interaction, 0.026). CONCLUSIONS: We found no evidence that the use of ACEIs or ARBs is associated with improved outcomes in patients with HF in the NH setting. However, we also found no evidence that this association is different in NH residents with HF versus non-NH patients with HF. Future larger studies are needed to demonstrate effectiveness of these drugs in the NH setting.

BACKGROUND: Characterization of myocardial structural changes in heart failure with preserved ejection fraction (HFpEF) has been hindered by the limited availability of human cardiac tissue. Cardiac hypertrophy, coronary artery disease (CAD), coronary microvascular rarefaction, and myocardial fibrosis may contribute to HFpEF pathophysiology. METHODS AND RESULTS: We identified HFpEF patients (n=124) and age-appropriate control subjects (noncardiac death, no heart failure diagnosis; n=104) who underwent autopsy. Heart weight and CAD severity were obtained from the autopsy reports. With the use of whole-field digital microscopy and automated analysis algorithms in full-thickness left ventricular sections, microvascular density (MVD), myocardial fibrosis, and their relationship were quantified. Subjects with HFpEF had heavier hearts (median, 538 g; 169% of age-, sex-, and body size-expected heart weight versus 335 g; 112% in controls), more severe CAD (65% with ≥1 vessel with >50% diameter stenosis in HFpEF versus 13% in controls), more left ventricular fibrosis (median % area fibrosis, 9.6 versus 7.1) and lower MVD (median 961 versus 1316 vessels/mm(2)) than control (P<0.0001 for all). Myocardial fibrosis increased with decreasing MVD in controls (r=-0.28, P=0.004) and HFpEF (r=-0.26, P=0.004). Adjusting for MVD attenuated the group differences in fibrosis. Heart weight, fibrosis, and MVD were similar in HFpEF patients with CAD versus without CAD. CONCLUSIONS: In this study, patients with HFpEF had more cardiac hypertrophy, epicardial CAD, coronary microvascular rarefaction, and myocardial fibrosis than controls. Each of these findings may contribute to the left ventricular diastolic dysfunction and cardiac reserve function impairment characteristic of HFpEF.

BACKGROUND: The prevalence and clinical significance of right ventricular (RV) systolic dysfunction (RVD) in patients with heart failure and preserved ejection fraction (HFpEF) are not well characterized. METHODS AND RESULTS: Consecutive, prospectively identified HFpEF (Framingham HF criteria, ejection fraction ≥50%) patients (n=562) from Olmsted County, Minnesota, underwent echocardiography at HF diagnosis and follow-up for cause-specific mortality and HF hospitalization. RV function was categorized by tertiles of tricuspid annular plane systolic excursion and by semiquantitative (normal, mild RVD, or moderate to severe RVD) 2-dimensional assessment. Whether RVD was defined by semiquantitative assessment or tricuspid annular plane systolic excursion ≤15 mm, HFpEF patients with RVD were more likely to have atrial fibrillation, pacemakers, and chronic diuretic therapy. At echocardiography, patients with RVD had slightly lower left ventricular ejection fraction, worse diastolic dysfunction, lower blood pressure and cardiac output, higher pulmonary artery systolic pressure, and more severe RV enlargement and tricuspid valve regurgitation. After adjustment for age, sex, pulmonary artery systolic pressure, and comorbidities, the presence of any RVD by semiquantitative assessment was associated with higher all-cause (hazard ratio=1.35; 95% confidence interval, 1.03-1.77; P=0.03) and cardiovascular (hazard ratio=1.85; 95% confidence interval, 1.20-2.80; P=0.006) mortality and higher first (hazard ratio=1.99; 95% confidence interval, 1.35-2.90; P=0.0006) and multiple (hazard ratio=1.81; 95% confidence interval, 1.18-2.78; P=0.007) HF hospitalization rates. RVD defined by tricuspid annular plane systolic excursion values showed similar but weaker associations with mortality and HF hospitalizations. CONCLUSIONS: In the community, RVD is common in HFpEF patients, is associated with clinical and echocardiographic evidence of more advanced HF, and is predictive of poorer outcomes.

Despite increasing recognition of the importance of right ventricular (RV) dysfunction (RVD) in the pathophysiology of left heart disease, our understanding of its epidemiology in heart failure (HF) with preserved ejection fraction (HFpEF) remains incomplete. In part, this is due to complex RV geometry and challenging and inconsistent assessment of RV function . Consequently, the prevalence of RVD in HFpEF varies widely depending on study design and population characteristics; however, on average is observed in one third of HFpEF subjects. In these patients, RVD is most commonly associated with an advanced HF state, pulmonary hypertension, atrial fibrillation, right ventricular pacing, and tricuspid valve regurgitation. Whether these associations are causal remains uncertain.Right ventricular dysfunction is recognized to confer poor outcomes in patients with HFpEF, including increased HF hospitalization and higher overall and cardiovascular mortality. Moreover, the prognostic significance of RVD in HFpEF is independent of, and additive to, the severity of pulmonary hypertension. As greater emphasis is placed on phenotyping subgroups of patients with HFpEF in order to tailor therapeutic strategies, improved characterization of the large subset of HFpEF patients with RVD, with and without antecedent pulmonary hypertension may yield critical insights, which inform novel therapeutic interventions.

Cardiac allograft vasculopathy (CAV) is a significant determinant of long-term survival in heart transplant recipients. Standard CAV screening typically utilizes invasive coronary angiography (ICA). Quantitative flow ratio (QFR) is a computational method for functional testing of coronary stenosis, and may add diagnostic value to ICA in assessing CAV. Consecutive subjects who received heart transplantation and underwent two separate routine coronary angiograms between January 2013 and April 2016 were enrolled. Coronary angiograms and IVUS were performed per local protocol at 1, 2, 3 and 5 years post-transplant. QFR was calculated offline. CAV was assessed semi-quantitively based on coronary angiogram results. Twenty-two patients were enrolled. Mean time from transplant to first included ICA was 2.1 years. QFR in at least 1 coronary vessel was interpretable in 19/22 (86%) of initial ICA (QFR1). QFR1 correlated well with the CAV score derived from the second ICA (CAV2) with a clustering of CAV at lower QFR values. In a receiver-operating characteristic (ROC) analysis, an optimal QFR threshold of 0.88 yielded 0.94 sensitivity and 0.67 specificity (AUC of 0.79) for at least non-obstructive subsequent CAV. Initial angiographically and intravascular ultrasound derived CAV severity poorly predicted subsequent CAV severity. QFR derived from invasive coronary angiography predicts subsequent development of CAV more accurately than angiography and intravascular ultrasound. This novel method of coronary flow assessment in recipients of heart transplantation may be useful to diagnose and predict subsequent CAV development.

Background: Transcatheter aortic valve replacement (TAVR) are not offered equitably to vulnerable population groups. Adequate levels of insurance may narrow gaps among patients with higher social vulnerability index (SVI). Among a national population of individuals with commercial or Medicare insurance, we sought to determine whether SVI was associated with urgency of receipt of TAVR for aortic stenosis. Methods and results: Using Optum's de-identified Clinformatics Data Mart Database (CDM), we identified admissions for TAVR with aortic stenosis between January 2018 and March 2022. Admission urgency was identified by CDM claims codes. SVI was cross-referenced to patient zip codes and grouped into quintiles. Generalized linear mixed effects models were used to predict the probability of a TAVR admission being urgent based on SVI quintiles, adjusting for patient and hospital-level covariates. Results: Among 6680 admissions for TAVR [median age 80 years (interquartile range 75-85), 43.9 % female], 8.5 % (n = 567) were classified as urgent. After adjusting for patient and hospital-level variables, there were no significant differences in the odds of urgent admission for TAVR according to SVI quintiles [OR 5th (greatest social vulnerability) vs 1st quintile (least social vulnerability): 1.29 (95 % CI: 0.90-1.85)]. Conclusions: Among commercial or Medicare beneficiaries with aortic stenosis, SVI was not associated with admission urgency for TAVR. To clarify whether cardiovascular care delivery is improved across SVI with higher paying beneficiaries, future investigation should identify whether relationships between SVI and TAVR urgency vary for Medicaid beneficiaries compared to commercial beneficiaries.
RESUMO
Multiple guidelines exist for the diagnosis and management of heart failure with preserved ejection fraction (HFpEF). We systematically reviewed current guidelines and recommendations, developed by national and international medical organizations, on the management of HFpEF in adults to aid clinical decision-making. We searched MEDLINE and EMBASE on 28 February 2024 for publications over the last 10 years as well as websites of organizations relevant to guideline development. Of the ten guidelines and recommendations retrieved, seven showed considerable rigour of development and were subsequently retained for analysis. There was consensus on the definition of HFpEF and the diagnostic role of serum natriuretic peptides and resting transthoracic echocardiography. Discrepancies were identified in the thresholds of serum natriuretic peptides and transthoracic echocardiography parameters used to diagnose HFpEF. There was agreement on the general pharmacological and supportive management of acute and chronic HFpEF. However, differences exist in strategies to identify and address specific phenotypes. Contemporary guidelines for HFpEF management agree on measures to avoid its development and the consideration of cardiac transplantation in advanced disease. There were discrepancies in recommended frequency of surveillance for patients with HFpEF and sparse recommendations on screening for HFpEF in the general population, use of diagnostic scoring systems, and the role of newly emerging therapies.
RESUMO
Maternal mortality is a major public health crisis in the United States. Cardiovascular disease (CVD) is a leading cause of maternal mortality and morbidity. Labor and delivery is a vulnerable time for pregnant individuals with CVD but there is significant heterogeneity in the management of labor and delivery in high-risk patients due in part to paucity of high-quality randomized data. The authors have convened a multidisciplinary panel of cardio-obstetrics experts including cardiologists, obstetricians and maternal fetal medicine physicians, critical care physicians, and anesthesiologists to provide a practical approach to the management of labor and delivery in high-risk individuals with CVD. This expert panel will review key elements of management from mode, timing, and location of delivery to use of invasive monitoring, cardiac devices, and mechanical circulatory support.
RESUMO
BACKGROUND: Sarcoidosis is associated with a poor prognosis. There is a lack of data examining the outcomes and readmission rates of sarcoidosis patients with heart failure (SwHF) and without heart failure (SwoHF). We aimed to compare the impact of non-ischemic heart failure on outcomes and readmissions in these two groups. METHODS: The US Nationwide Readmission Database was queried from 2010 to 2019 for SwHF and SwoHF patients identified using the International Classification of Diseases, 9th and 10th Editions. Those with ischemic heart disease were excluded, and both cohorts were propensity matched for age, gender, and Charlson Comorbidity Index (CCI). Clinical characteristics, length of stay, adjusted healthcare-associated costs, 90-day readmission and mortality were analyzed. RESULTS: We identified 97,961 hospitalized patients (median age 63 years, 37.9% male) with a diagnosis of sarcoidosis (35.9% SwHF vs 64.1% SwoHF). On index admission, heart failure patients had higher prevalences of atrioventricular block (3.3% vs 1.4%, P < .0001), ventricular tachycardia (6.5% vs 1.3%, P < .0001), ventricular fibrillation (0.4% vs 0.1%, P < .0001) and atrial fibrillation (22.1% vs 7.5%, P < .0001). SwHF patients were more likely to be readmitted (hazard ratio 1.28, P < .0001), had higher length of hospital stay (5 vs 4 days, P < .0001), adjusted healthcare-associated costs ($9,667.0 vs $9,087.1, P < .0001) and mortality rates on readmission (5.1% vs 3.8%, P < .0001). Predictors of mortality included heart failure, increasing age, male sex, higher CCI, and liver disease. CONCLUSION: SwHF is associated with higher rates of arrhythmia at index admission, as well as greater hospital cost, readmission and mortality rates compared to those without heart failure.

AIMS: The pathophysiology of heart failure with preserved ejection fraction (HFpEF) is complex but increased left ventricular (LV) diastolic stiffness plays a key role. A load-independent, non-invasive, direct measure of diastolic stiffness is lacking. The diastolic wall strain (DWS) index is based on the linear elastic theory, which predicts that impaired diastolic wall thinning reflects resistance to deformation in diastole and thus, increased diastolic myocardial stiffness. The objectives of this community-based study were to determine the distribution of this novel index in consecutive HFpEF patients and healthy controls, define the relationship between DWS and cardiac structure and function and determine whether increased diastolic stiffness as assessed by DWS is predictive of the outcome in HFpEF. METHODS AND RESULTS: Consecutive HFpEF patients (n = 327, EF ≥ 50%) and controls (n = 528) from the same community were studied. Diastolic wall strain was lower in HFpEF (0.33 ± 0.08) than in controls (0.40 ± 0.07, P < 0.001). Within HFpEF, those with DWS ≤ median (0.33) had higher LV mass index, relative wall thickness, E/e', Doppler-estimated LV end-diastolic pressure to LV end-diastolic volume ratio, left atrial volume index, and brain natriuretic peptide (BNP) levels than those with DWS > median. Heart failure with preserved ejection fraction patients with DWS ≤ median had higher rate of death or HF hospitalization than those with DWS > median (P = 0.003) even after the adjustment for age, gender, log BNP, LV geometry, or log E/e' (P < 0.01). CONCLUSION: These data suggest that DWS, a simple index, is useful in assessing diastolic stiffness and that more advanced diastolic stiffness is associated with worse outcomes in HFpEF.

BACKGROUND: Durable left ventricular assist devices (VADs) improve survival in eligible patients, but allocation has been associated with patient race in addition to presumed heart failure (HF) severity. OBJECTIVES: This study sought to determine racial and ethnic differences in VAD implantation rates and post-VAD survival among patients with ambulatory HF. METHODS: Using the INTERMACS (Interagency Registry of Mechanically Assisted Circulatory Support) database (2012-2017), this study examined census-adjusted VAD implantation rates by race, ethnicity, and sex in patients with ambulatory HF (INTERMACS profile 4-7) using negative binomial models with quadratic effect of time. Survival was evaluated using Kaplan-Meier estimates and Cox models adjusted for clinically relevant variables and an interaction of time with race/ethnicity. RESULTS: VADs were implanted in 2,256 adult patients with ambulatory HF (78.3% White, 16.4% Black, and 5.3% Hispanic). The median age at implantation was lowest in Black patients. Implantation rates peaked between 2013 and 2015 before declining in all demographic groups. From 2012 to 2017, implantation rates overlapped for Black and White patients but were lower for Hispanic patients. Post-VAD survival was significantly different among the 3 groups (log rank P = 0.0067), with higher estimated survival among Black vs White patients (12-month survival: Black patients: 90% [95% CI: 86%-93%]; White patients: 82% [95% CI: 80%-84%]). Low sample size for Hispanic patients resulted in imprecise survival estimates (12-month survival: 85% [95% CI: 76%-90%]). CONCLUSIONS: Black and White patients with ambulatory HF had similar VAD implantation rates but rates were lower for Hispanic patients. Survival differed among the 3 groups, with the highest estimated survival at 12 months in Black patients. Given higher HF burden in minoritized populations, further investigation is needed to understand differences in VAD implantation rates in Black and Hispanic patients.

BACKGROUND: Black patients with peripartum cardiomyopathy (PPCM) have disproportionately worse outcomes than White patients, possibly related to variable involvement of cardiovascular specialists in their clinical care. We sought to determine whether race was associated with cardiology involvement in clinical care during inpatient admission and whether cardiology involvement in care was associated with higher claims of guideline-directed medical therapy (GDMT) a week after hospital discharge. METHODS: Using Optum's de-identified Clinformatics® Data Mart (CDM), we included Black and White patients' first hospital admission for PPCM from 2008 to 2021. Cardiology involvement in clinical care was defined as the receipt of attending care from a cardiovascular specialist during admission. GDMT included beta-blockers (BB) for all patients and triple therapy (BB, angiotensin-responsive medications, and mineralocorticoid receptor antagonists) for non-pregnant patients. Logistic regression was used to determine the associations between cardiology involvement in clinical care during admission and (1) patient race and (2) GDMT prescription, adjusting for age and comorbidities. RESULTS: Among 668 patients (32.6% Black, 67.4% White, 93.3% commercially insured), there was no significant difference in the odds of cardiology involvement in clinical care by race (aOR: 1.41; 95%CI: 0.87-2.33, P=0.17). Inpatient cardiology care was associated with 2.75 times increased odds of having a prescription claim for GDMT (BB) for White patients (aOR: 2.75; 95%CI 1.50-5.06, P=0.001), and the estimated effect size was similar but not statistically significant for Black patients (aOR: 2.20, 95% CI, 0.84-5.71, P=0.11). The interaction between race and cardiology involvement in clinical care was not statistically significant for the receipt of BB prescription. Among 274 non-pregnant patients with PPCM (37.2% Black, 62.8% White), 5.8% received triple GDMT. Of these, none of the Black patients lacking cardiology care had triple GDMT. However, cardiology involvement in care was not significantly associated with triple GDMT for either race. CONCLUSIONS: Among a commercially insured population within PPCM, race was not associated with cardiology involvement in clinical care during hospitalization. However, cardiology involvement in care was associated with significantly higher odds of prescription claims for BB for only White patients. Additional strategies are needed to support equitable GDMT prescription.
