RESUMEN

BACKGROUND: Heart failure (HF) has unique aspects that vary by biological sex. Thus, understanding sex-specific trends of HF in the US population is crucial to develop targeted interventions. We aimed to analyze the burden of HF in female and male patients across the US, from 1990 to 2019. METHODS: Using the Global Burden of Disease (GBD) study data from 2019, we performed an analysis of the burden of HF from 1990-2019, across US states and regions. The GBD defined HF through studies that used symptom-based criteria and expressed the burden of HF as the age-adjusted prevalence and years lived with disability (YLDs) rates per 100,000 individuals. RESULTS: The age-adjusted prevalence of HF for the US in 2019 was 926.2 (95% UI [799.6, 1,079.0]) for females and 1,291.2 (95% UI [1,104.1, 1,496.8]) for males. Notably, our findings also highlight cyclic fluctuations in HF prevalence over time, with peaks occurring in the mid-1990s and around 2010, while reaching their lowest points in around 2000 and 2018. Among individuals >70 years of age, the absolute number of individuals with HF was higher in females, and this age group doubled the absolute count between 1990 and 2019. Comparing 1990-1994 to 2015-2019, 10 states had increased female HF prevalence, while only 4 states increased male prevalence. Overall, Western states had the greatest relative decline in HF burden, in both sexes. CONCLUSION: The burden of HF in the US is high, although the magnitude of this burden varies according to age, sex, state, and region. There is a significant increase in the absolute number of individuals with HF, especially among women >70 years, expected to continue due to the aging population.

RESUMEN

Obesity has become a worldwide public health issue. Many obese patients concomitantly suffer with heart failure with reduced ejection fraction. There have been reports of improvement in left ventricular systolic function following significant weight loss after bariatric surgery. We sought to investigate this phenomenon within our institution. This was a retrospective single-center analysis of patients conducted between 2010 and 2019. The study included patients with morbid obesity (body mass index >35 kg/m2 and an obesity-related comorbid condition, or a body mass index >40 kg/m2) and left ventricular systolic dysfunction. Analysis was performed based on systolic function recovery after bariatric surgery and advanced heart failure therapy. Of the 190 patients identified, 57 patients had a left ventricular ejection fraction of <40%. Twenty-two patients underwent bariatric surgery, of which at least 54.5% had systolic function recovery. Patients who had systolic function recovery after bariatric surgery were significantly older (51.58 years ± 10.48 vs 32.3 years ± 5.03, P = 0.001). Older age and female sex were predictors of systolic function recovery. In patients with obesity and heart failure with reduced ejection fraction, weight loss following bariatric surgery was shown to be correlated with significant improvement in left ventricular systolic function.

RESUMEN

Cardiac allograft vasculopathy (CAV) is the leading cause of long-term graft dysfunction in patients with heart transplantation and is linked with significant morbidity and mortality. Currently, the gold standard for diagnosing CAV is coronary imaging with intravascular ultrasound during traditional invasive coronary angiography. Invasive imaging, however, carries increased procedural risk and expense to patients in addition to requiring an experienced interventionalist. With the improvements in non-invasive cardiac imaging modalities such as transthoracic echocardiography, computed tomography, magnetic resonance imaging and positron emission tomography, an alternative non-invasive imaging approach for the early detection of CAV may be feasible. In this systematic review, we explored the literature to investigate the utility of non-invasive imaging in diagnosis of CAV in >3000 patients across 49 studies. We also discuss the strengths and weaknesses for each imaging modality. Overall, all 4 imaging modalities show good to excellent accuracy for identifying CAV with significant variations across studies. Majority of the studies compared non-invasive imaging with invasive coronary angiography without intravascular imaging. In summary, non-invasive imaging modalities offer an alternative approach to invasive coronary imaging for CAV. Future studies should investigate longitudinal non-invasive protocols in low-risk patients after heart transplantation.

RESUMEN

Myocarditis can be refractory to medical therapy and require durable mechanical circulatory support (MCS). The characteristics and outcomes of these patients are not known. We identified all patients with clinically-diagnosed or pathology-proven myocarditis who underwent mechanical circulatory support in the International Society for Heart and Lung Transplantation Registry for Mechanically Assisted Circulatory Support registry (2013-2016). The characteristics and outcomes of these patients were compared to those of patients with nonischemic cardiomyopathy (NICM). Out of 14,062 patients in the registry, 180 (1.2%) had myocarditis and 6,602 (46.9%) had NICM. Among patients with myocarditis, duration of heart failure was <1 month in 22%, 1-12 months in 22.6%, and >1 year in 55.4%. Compared with NICM, patients with myocarditis were younger (45 vs. 52 years, P < 0.001) and were more often implanted with Interagency Registry for Mechanically Assisted Circulatory Support profile 1 (30% vs. 15%, P < 0.001). Biventricular mechanical support (biventricular ventricular assist device [BIVAD] or total artificial heart) was implanted more frequently in myocarditis (18% vs. 6.7%, P < 0.001). Overall postimplant survival was not different between myocarditis and NICM (left ventricular assist device: P = 0.27, BIVAD: P = 0.50). The proportion of myocarditis patients that have recovered by 12 months postimplant was significantly higher in myocarditis compared to that of NICM (5% vs. 1.7%, P = 0.0003). Adverse events (bleeding, infection, and neurologic dysfunction) were all lower in the myocarditis than NICM. In conclusion, although myocarditis patients who receive durable MCS are sicker preoperatively with higher needs for biventricular MCS, their overall MCS survival is noninferior to NICM. Patients who received MCS for myocarditis are more likely than NICM to have MCS explanted due to recovery, however, the absolute rates of recovery were low.

RESUMEN

BACKGROUND: The Model for End-Stage Liver Disease (MELD) score was originally described as a marker of survival in chronic liver disease. More recently, MELD and its derivatives, MELD excluding INR (MELD-XI) and MELD with sodium (MELD-Na), have been applied more broadly as outcome predictors in heart transplant, left ventricular assist device placement, heart failure, and cardiogenic shock, with additional promising data to support the use of these scores for prediction of survival in those undergoing veno-arterial extracorporeal membrane oxygenation (VA ECMO). METHODS: This study assessed the prognostic impact of MELD in patients with cardiogenic shock undergoing VA ECMO via a single-center retrospective review from January 2014 to March 2020. MELD, MELD-XI, and MELD-Na scores were calculated using laboratory values collected within 48 h of VA ECMO initiation. Multivariate Cox regression analyses determined the association between MELD scores and the primary outcome of 90-day mortality. Receiver operating characteristics (ROC) were used to estimate the discriminatory power for MELD in comparison with previously validated SAVE score. RESULTS: Of the 194 patients, median MELD was 20.1 (13.7-26.2), and 90-day mortality was 62.1%. There was a significant association between MELD score and mortality up to 90 days (hazard ratio (HR) = 1.945, 95% confidence interval (95% CI) = 1.244-3.041, p = 0.004) after adjustment for age, indication for VA ECMO, and sex. The prognostic significance of MELD score for 90-day mortality revealed an AUC of 0.645 (95% CI = 0.565-0.725, p < 0.001). MELD-Na score and MELD-XI score were not associated with mortality. CONCLUSION: MELD score accurately predicts long-term mortality and may be utilized as a valuable decision-making tool in patients undergoing VA ECMO.

RESUMEN

Peak exercise oxygen consumption (pVO2) is an important predictor of prognosis in patients with heart failure (HF). The association between pretransplant pVO2 and post-transplantation outcomes in HF patients has not been previously studied. We identified adult OHT recipients with available pVO2 in the United Network for Organ Sharing registry (2000 to 2015). Patients were divided into 3 categories using Weber classification: class B (pVO2 16 to 20 ml/kg/min), class C (pVO2 10 to 16 ml/kg/min), and class D (pVO2 <10 ml/kg/min). Postoperative outcomes (mortality, renal failure, rejection) were compared between the groups. A total of 9,623 patients were included in this analysis; the mean age was 54 ± 11 years, 74% were male, 75% were white and 59% had nonischemic etiology of HF. The mean pVO2 was 11.7 ± 3.6 ml/kg/min: 1,202 (12.5%) in class B, 6,055 (62.9%) in class C, and 2,366 (24.6%) were in class D. At a median follow-up of 6.1 years, 2,730 (28.4%) died. Post-transplantation survival decreased with decreasing pVO2; 1 and 5-year survival: B (92%, 80%), C (90%, 79%), and D (87%, 75%), p <0.001 by log-rank. After multiple adjustments, patients in class D had significantly higher post-transplantation mortality compared with class C (Hazard Ratio (HR) 1.21 [1.03 to 1.43], p = 0.02). When analyzed as a continuous variable, each 1 ml/kg/min increase in pVO2 was associated with 2% decrease in mortality during follow-up (adjusted HR 0.98 [0.96 to 0.99], p <0.001). Patients in class D had significantly prolonged (>14 days) hospitalization (adjusted Odds Ratio (OR) 1.42 [1.20 to 1.68], p <0.001) and a trend toward increased need for dialysis (adjusted OR 1.36 [1.00 to 1.84], p = 0.05) compared with patients in class B. In this large cohort, lower pretransplant pVO2 was associated with greater mortality and morbidity after OHT. These results suggest that earlier transplantation might improve post-transplantation outcomes in advanced HF patients.

RESUMEN

BACKGROUND: Cardiogenic shock is associated with significant mortality, morbidity, and healthcare cost. Utilization of extracorporeal membrane oxygenation in cardiogenic shock has increased in the United States. We sought to identify the rates and predictors of hospital readmissions in patients with cardiogenic shock after weaning from extracorporeal membrane oxygenation. METHODS: Using the 2016 Nationwide Readmission Database, we identified all patients (⩾18 years) with cardiogenic shock (ICD-10 CM R57.0) that have been implanted with extracorporeal membrane oxygenation (ICD-10-PSC of 5A15223) and were discharged alive (January-November 2016). We explored the rates, causes, and predictors of all-cause readmissions within 30 days. RESULTS: Out of 69,040 admissions with cardiogenic shock, 1641 (2.4%) underwent extracorporeal membrane oxygenation (581 were implanted during or after cardiac surgery). A total of 734 (44.7%) patients of all extracorporeal membrane oxygenations survived to discharge, and 661 were available for analysis. Out of those, 158 (23.9%) were readmitted within 30 days of discharge. More than 50% of these readmissions happened within the first 11 days. Out of 158 patients who were readmitted, 12 (7.4%) died during the readmission hospitalization. Leading causes of readmission were cardiovascular (31.6%) (heart failure: 24.1%, arrhythmia: 20.6%, neurovascular: 10.3%, hypertension: 10.3%, and endocarditis: 6.8%), followed by complications of medical/device care (17.7%), infection (11.3%), and gastrointestinal/liver (10.1%) complications. Factors associated with readmissions include the following: discharge to skilled nursing facility or with home healthcare (odds ratio: 2.10; 95% confidence interval: 1.18-3.74), durable ventricular assisted device implantation, asthma, and chronic liver disease. CONCLUSION: Patients with cardiogenic shock who underwent extracorporeal membrane oxygenation had a readmission rate. Identifying patients at high risk of readmissions might help improve outcomes.

RESUMEN

Removal of the HeartMate II left ventricular assist device (LVAD) usually requires a sternotomy. We report a case of HeartMate III LVAD implantation to the descending aorta via a left thoracotomy while leaving most of the HeartMate II device in place to avoid redo-sternotomy.

RESUMEN

BACKGROUND: Sunitinib, used widely in metastatic renal cell carcinoma, can result in hypertension, left ventricular dysfunction, and heart failure. However, the relationships between vascular function and cardiac dysfunction with sunitinib are poorly understood. METHODS AND RESULTS: In a multicenter prospective study of 84 metastatic renal cell carcinoma patients, echocardiography, arterial tonometry, and BNP (B-type natriuretic peptide) measures were performed at baseline and at 3.5, 15, and 33 weeks after sunitinib initiation, correlating with sunitinib cycles 1, 3, and 6. Mean change in vascular function parameters and 95% confidence intervals were calculated. Linear regression models were used to estimate associations between vascular function and left ventricular ejection fraction, longitudinal strain, diastolic function (E/e'), and BNP. After 3.5 weeks of sunitinib, mean systolic blood pressure increased by 9.5 mm Hg (95% confidence interval, 2.0-17.1; P=0.02) and diastolic blood pressure by 7.2 mm Hg (95% confidence interval, 4.3-10.0; P<0.001) across all participants. Sunitinib resulted in increases in large artery stiffness (carotid-femoral pulse wave velocity) and resistive load (total peripheral resistance and arterial elastance; all P<0.05) and changes in pulsatile load (total arterial compliance and wave reflection). There were no statistically significant associations between vascular function and systolic dysfunction (left ventricular ejection fraction and longitudinal strain). However, baseline total peripheral resistance, arterial elastance, and aortic impedance were associated with worsening diastolic function and filling pressures over time. CONCLUSIONS: In patients with metastatic renal cell carcinoma, sunitinib resulted in early, significant increases in blood pressure, arterial stiffness, and resistive and pulsatile load within 3.5 weeks of treatment. Baseline vascular function parameters were associated with worsening diastolic but not systolic function.

RESUMEN

PURPOSE OF REVIEW: The aim of this study is to summarize the literature describing the pathogenesis, diagnosis and management of cardiomyopathy related to myocarditis. RECENT FINDINGS: Myocarditis has a variety of causes and a heterogeneous clinical presentation with potentially life-threatening complications. About one-third of patients will develop a dilated cardiomyopathy and the pathogenesis is a multiphase, mutlicompartment process that involves immune activation, including innate immune system triggered proinflammatory cytokines and autoantibodies. In recent years, diagnosis has been aided by advancements in cardiac MRI, and in particular T1 and T2 mapping sequences. In certain clinical situations, endomyocardial biopsy (EMB) should be performed, with consideration of left ventricular sampling, for an accurate diagnosis that may aid treatment and prognostication. SUMMARY: Although overall myocarditis accounts for a minority of cardiomyopathy and heart failure presentations, the clinical presentation is variable and the pathophysiology of myocardial damage is unique. Cardiac MRI has significantly improved diagnostic abilities, but endomyocardial biopsy remains the gold standard. However, current treatment strategies are still focused on routine heart failure pharmacotherapies and supportive care or cardiac transplantation/mechanical support for those with end-stage heart failure.

RESUMEN

Mitral valve repair with the MitraClip device has emerged as an effective treatment option for patients with severe mitral regurgitation and contraindications for surgical interventions. While the procedure is not known to cause pulmonary complications, we describe two cases of pulmonary hemorrhage following percutaneous mitral valve repair. The patients did well with supportive care and reinitiation of anticlotting agents was well tolerated after resolution of bleeding.

RESUMEN

BACKGROUND: Giant cell myocarditis (GCM) is a lethal, rapidly progressive disease, for which heart transplantation is the treatment of choice. We sought to describe the characteristics and outcomes of patients with GCM who undergo heart transplantation. METHODS AND RESULTS: We used the United Network for Organ Sharing thoracic organ transplantation registry to identify adults with GCM as the primary diagnosis and compared their characteristics and outcomes with patients who underwent transplantation for other types of myocarditis and for idiopathic dilated cardiomyopathy (IDCMP). A total of 32 patients with GCM were compared with 219 patients with myocarditis and 14,221 patients with IDCMP. Median age at listing for GCM was 52 years (interquartile range 40-55 y), and the majority were white (94%), male (63%), and listed as 1A (44%). Biventricular assist devices were used more frequently in GCM compared with IDCMP (31% vs 2%; P < .001). After transplantation, there were no statistically significant differences among GCM, myocarditis, and IDCMP patients regarding pacemaker implantation, dialysis initiation, or stroke rate. GCM patients had increased risk of acute rejection compared with IDCMP patients (16% vs 5.0%; P = .021) but no difference in rehospitalization for rejection among the 3 etiologies (P = .88). The cumulative survivals for GCM patients at 1, 5, and 10 years were 94%, 82%, and 68%, respectively, which was similar to the other etiologies (P = .11). CONCLUSIONS: Compared with patients with IDCMP, those with GCM present more acutely and have significantly higher utilization of biventricular mechanical circulatory support. Despite higher rates of early rejection, post-transplantation survival of patients with GCM was similar to that of other myocarditides and IDCMP.

RESUMEN

Purpose: To prospectively evaluate cardiotoxicity risk with sunitinib in metastatic renal cell carcinoma (mRCC) routine clinical practice using comprehensive echocardiography and biomarker phenotyping.Experimental Design: In a multicenter prospective study of 90 patients with mRCC, echocardiography and biomarkers of cardiovascular injury and stress were quantified at baseline, 3.5, 15, and 33 weeks following sunitinib initiation. These "on-drug" visits corresponded to cycles 1, 3, and 6, respectively. Left ventricular (LV) dysfunction was defined as an absolute decline in LV ejection fraction (LVEF) by ≥10% to a value of <50%. Conditional survival analyses predicted the risk of LV dysfunction. Linear mixed-effects models estimated changes in LVEF, high-sensitivity Troponin I (hsTnI), and B-type natriuretic peptide (BNP) over time.Results: The predicted risk of LV dysfunction by cycle 6 was 9.7% (95% confidence interval, 3%-17%). The majority of events occurred in the first treatment cycle. This risk diminished to 5% and 2% in patients who had not experienced dysfunction by the completion of cycles 1 and 3, respectively. All evaluable patients who experienced LV dysfunction had subsequent improvement in LVEF with careful management. Six patients (6.7%) developed hsTnI elevations >21.5 pg/mL, and 11 additional patients (12.2%) developed BNP elevations >100 pg/mL. These elevations similarly tended to occur early and resolved over time.Conclusions: On average, patients with mRCC receiving sunitinib exhibit modest declines in LVEF and nonsignificant changes in hsTnI and BNP. However, approximately 9.7% to 18.9% of patients develop more substantive abnormalities. These changes occur early and are largely recoverable with careful management.

RESUMEN

BACKGROUND: Fixed pulmonary hypertension is common in patients with advanced heart failure and is a contraindication for heart transplantation. Left ventricular assist devices (LVAD) and inotropes have been used to reduce pulmonary vascular resistance (PVR) and allow transplantation. However, little is known about the efficacy of this strategy. METHODS: We queried the United Network for Organ Sharing registry for all adult patients (age ≥18 years) listed for primary heart transplantation (2008-2014) with PVR of >5 wood units (WU) or transpulmonary gradient >16 mmHg who were treated with LVAD or IV inotropes as status 1a, 1b, or 7. We compared waitlist mortality/delisting and absolute changes in hemodynamics between listing and transplantation. RESULTS: Of 18,009 patients listed during the study period, 1016 were included in the analysis (393 LVAD, 623 inotropes), with a mean age of 52.9 ± 11.6 years, 74% male, and 38% had ischemic etiology. Mean PVR was 5.7 ± 2.4 WU and transpulmonary pressure gradient 19.3 ± 5.3 mmHg. Compared with the inotrope group, LVAD patients were more likely listed as status 1A (32.8% vs 18.1%, P < .001), had lower PVR (5.3 WU vs 5.9 WU, P = .001), and higher cardiac output (4.1 vs 3.6 L/min, P < .001). After a mean of 239 days, PVR decreased by 1.71 WU in the LVAD group vs 1.85 WU in the inotrope group (P = .52). PVR normalization (<2.5 WU) occurred at similar rates among those treated with inotropes and LVAD (30.7% vs 35.6%, P = .228). Waitlist mortality was similar between LVAD and inotropes (adjusted P = .837). Absolute PVR and transpulmonary pressure gradient reductions correlated with time on the waitlist (P < .001 for both comparisons). CONCLUSION: Only about one-third of patients with fixed pulmonary hypertension achieve normalization of PVR before transplant with either LVAD or inotropes. Similar waitlist mortality was observed among patients bridged with either strategy.

RESUMEN

BACKGROUND: Myocarditis can cause dilated cardiomyopathy resulting in end-stage heart failure requiring advanced therapies. There is little contemporary information on the clinical progression, need for mechanical circulatory support, and outcomes of orthotopic heart transplantation of these patients. METHODS AND RESULTS: We queried the UNOS database (United Network for Organ Sharing) for all adults listed for orthotopic heart transplantation (2000-2015) with a listed diagnosis of myocarditis. Comparative and survival analyses were performed. Of 45 941 adults listed for orthotopic heart transplantation during this period, we identified 299 patients (0.7%) with the diagnosis of myocarditis. Compared with patients with nonischemic cardiomyopathy (NICM) and ischemic cardiomyopathy (ICM), myocarditis patients were younger (myocarditis 43.4±14.2 years, NICM 49.8±12.4 years, and ICM 57.5±8.0 years; P<0.001) and more frequently listed as status 1A (myocarditis 44% versus NICM 21% versus ICM 21%; P<0.001), with significantly higher need for mechanical ventilation (myocarditis 11% versus NICM 2% versus ICM 4%; P<0.001), biventricular mechanical circulatory support (myocarditis 19% versus NICM 2%, versus ICM 2%; P<0.001), and extracoroporeal membrane oxygenation (myocarditis 5% versus NICM 0.4% versus ICM 1%; P<0.001). Additionally, patients with myocarditis had higher likelihood of delisting for clinical improvement (hazard ratio, 2.49 [95% confidence interval, 1.63-3.79] versus ICM and hazard ratio, 2.12 [95% confidence interval, 1.40-3.22] versus NICM; P<0.001). Despite higher allosensitization, patients with myocarditis had similar post-transplant rejection, retransplantation, and survival rates compared with other groups. CONCLUSIONS: Patients with the diagnosis of myocarditis listed for orthotopic heart transplantation are younger, sicker, and recover more frequently but require more biventricular mechanical circulatory support. Heart transplantation survival is comparable to that of patients with other types of heart failure.

RESUMEN

Concerns exist regarding orthotropic heart transplantation in hepatitis C virus (HCV) seropositive recipients. Thus, a national registry was accessed to evaluate early and late outcome in HCV seropositive recipients undergoing heart transplant. Retrospective analysis of the United Network for Organ Sharing registry (1991 to 2014) was performed to evaluate recipient profile and clinical outcome of patients with HCV seropositive (HCV +ve) and seronegative (HCV -ve). Adjusted results of early mortality and late survival were compared between cohorts. From 23,507 patients (mean age 52 years; 75% men), 481 (2%) were HCV +ve (mean age 52 years; 77% men). Annual proportion of HCV +ve recipients was comparable over the study period (range 1.3% to 2.7%; p = 0.2). The HCV +ve cohort had more African-American (22% vs 17%; p = 0.01), previous left ventricular assist device utilization (21% vs 14%; p <0.01) and more hepatitis B core Ag+ve recipients (17% vs 5%; p <0.01). However, both cohorts were comparable in terms of extracorporeal membrane oxygenator usage (p = 0.7), inotropic support (p = 0.2), intraaortic balloon pump (p = 0.7) support, serum creatinine (p = 0.7), and serum bilirubin (p = 0.7). Proportion of status 1A patients was similar (24% HCV + vs 21% HCV -); however, wait time for HCV +ve recipients were longer (mean 23 vs 19 days; p <0.01). Among donor variables, age (p = 0.8), hepatitis B status (p = 0.4), and Center for Diseases Control high-risk status (p = 0.9) were comparable in both cohorts. At a median follow-up of 4 years, 67% patients were alive, 28% died, and 1.1% were retransplanted (3.4% missing). Overall survival was worse in the HCV+ cohort (64.3% vs 72.9% and 43.2% vs 55% at 5 and 10 years; p <0.01), respectively. Late renal (odds ratio [OR] 1.2 [1 to 1.6]; p = 0.02) and liver dysfunction (odds ratio 4.5 [1.2 to 15.7]; p = 0.01) occurs more frequently in HCV +ve recipients. On adjusted analysis, HCV seropositivity is associated with poorer survival (hazard ratio for mortality 1.4 [1.1 to 1.6]; p <0.001). In conclusion, a small proportion of patients receiving a heart transplant in the United States have hepatitis C. Despite comparable preoperative hepatic function, hepatitis C seropositive recipients demonstrate poorer long-term survival.
