Association of device detected atrial and ventricular tachyarrhythmia with adverse events in patients with an implantable cardioverter-defibrillator.

INTRODUCTION: Heart failure patients with a history of atrial fibrillation (AF) and ventricular tachycardia/ventricular fibrillation (VT/VF) are known to have worse outcomes. However, there are limited data on the temporal relationship between development of these arrhythmias and the risk of subsequent congestive heart failure (CHF) exacerbation and death. METHODS: The study cohort comprised 5511 patients implanted with an implantable cardioverter-defibrillator (ICD) in landmark clinical trials (MADIT-II, MADIT-RISK, MADIT-CRT, MADIT-RIT, and RAID) who were in sinus rhythm at enrollment. Multivariate cox analysis was performed to evaluate the time-dependent association between development of in-trial device detected AF and VT/VF with subsequent CHF exacerbation and death. RESULTS: Multivariate analysis showed that AF occurrence and VT/VF occurrence were both associated with a similar magnitude of risk for subsequent CHF exacerbation (HR = 1.73 and 1.87 respectively, p < .001 for both). In contrast, only in-trial VT/VF was associated with a significant > two-fold increase in the risk of subsequent mortality (HR = 2.13, p < .001) whereas AF occurrence was not associated with a significant mortality increase after adjustment for in-trial VT/VF (HR = 1.36, p = .096). CONCLUSION: Our findings from a large cohort of ICD recipients enrolled in landmark clinical trials show that device detected AF and VT/VF can be used to identify patients with increased risk for CHF exacerbation and mortality. These findings suggest a need for early intervention in CHF patients who develop device-detected atrial and ventricular tachyarrhythmias.

Experimentally Induced Peripheral Venous Congestion Exacerbates Inflammation, Oxidative Stress, and Neurohormonal and Endothelial Cell Activation in Patients With Systolic Heart Failure.

BACKGROUND: Venous congestion (VC) is a hallmark of symptomatic heart failure (HF) requiring hospitalization; however, its role in the pathogenesis of HF progression remains unclear. We investigated whether peripheral VC exacerbates inflammation, oxidative stress and neurohormonal and endothelial cell (EC) activation in patients with HF with reduced ejection fraction (HFrEF). METHODS AND RESULTS: Two matched groups of patients with HFrEF and with no peripheral VC vs without recent HF hospitalization were studied. We modeled peripheral VC by inflating a cuff around the dominant arm, targeting ∼ 30 mmHg increase in venous pressure (venous stress test [VST]). Blood and ECs were sampled before and after 90 minutes of VST. We studied 44 patients (age 53 ± 12 years, 32% female). Circulating endothelin-1, tumor necrosis factor-α, interleukin-6, isoprostane, angiotensin II (ang-2), angiopoietin-2, vascular cell adhesion molecule-1, and CD146 significantly increased after the VST. Enhanced endothelin-1 and angiopoietin-2 responses to the VST were present in patients with vs without recent hospitalization and were prospectively associated with incident HF-related events; 6698 messenger ribonucleic acid (mRNA probe sets were differentially expressed in ECs after VST. CONCLUSIONS: Experimental VC exacerbates inflammation, oxidative stress, neurohormonal and EC activation and promotes unfavorable transcriptome remodeling in ECs of patients with HFrEF. A distinct biological sensitivity to VC appears to be associated with high risk for HF progression.

Takotsubo pathophysiology and complications: what we know and what we do not know.

Takotsubo cardiomyopathy or stress cardiomyopathy (SCM), was first described in 1990 and initially, it was thought to be only associated with short-term complications and mortality with a benign long-term prognosis comparable to a healthy population. However recent investigations have proven otherwise and have shown SCM patients might have comparable long-term morbidity and mortality to ST-elevation myocardial infarction (STEMI) patients. Many emotional, or physical stressors can trigger SCM, and have been able to describe an interplay of neurohormonal and inflammatory mechanisms as the pathophysiology of this disease. Additionally, given the significantly higher prevalence of SCM in post-menopausal women, estrogen levels have been thought to play a role in the pathogenesis of this disease. Furthermore, there is an elusive disparity in prognosis depending upon different triggers. Currently, many questions remain unanswered regarding the long-term management of these patients to reduce morbidity, mortality, and improve quality of life, such as the need for long-term anticoagulation. In this paper, we review the findings of most recent published investigations regarding etiologies, pathophysiology, diagnostic criteria, prognosis, short-term and in more detail, long-term complications of SCM. Finally, we will discuss what future research is needed to learn more about this disease to improve the long-term prognosis, even though as of now, data for long-term management is still lacking.

Locoregional anesthesia is associated with decreased cardiac complications in symptomatic heart failure patients undergoing carotid endarterectomy.

OBJECTIVE: Although the current literature reports no advantage for locoregional anesthesia (LRA) over general anesthesia (GA) in patients undergoing carotid endarterectomy (CEA), there remains a gap in understanding the impact of LRA on individuals with congestive heart failure (CHF). This study aims to assess whether the choice of anesthesia influences the rates of perioperative complications within this patient population. METHODS: Using the Vascular Quality Initiative CEA module, all patients undergoing CEA between 2013 and 2023 were identified. The subset of patients with CHF was included, and patients were divided based on the type of anesthesia received. Patient characteristics and outcomes were compared using the χ2 or Fischer's exact test as appropriate for categorical variables and the independent t test or Mann-Whitney U test as appropriate for continuous variables. A sensitivity analysis was performed based on the symptomatic status of CHF, and the association between anesthesia modality and postoperative outcomes was studied using multivariable logistic regression analysis. The primary outcomes of this study included perioperative stroke, myocardial infarction (MI), acute HF, and the combination of MI and acute HF defined as major cardiac complications. RESULTS: A total of 21,292 patients (19,730 receiving GA, 1562 receiving LRA) with a diagnosis of CHF undergoing CEA were identified. On multivariable logistic regression analysis, LRA was independently associated with lower MI (odds ratio [OR]; 0.35; 95% confidence interval [CI], 0.13-0.96), acute HF (OR, 0.27; 95% CI, 0.09-0.87), major cardiac complications (OR, 0.30; 95% CI, 0.13-0.67), hemodynamic instability (OR, 0.64; 95% CI, 0.53-0.78), cranial nerve injury (OR, 0.40; 95% CI, 0.19-0.81), shunt use (OR, 0.25; 95% CI, 0.20-0.31), and neuromonitoring device use (OR, 0.20; 95% CI, 0.17-0.24) compared with GA in patients with symptomatic CHF. No difference in MI, acute HF, and major cardiac complications was seen in patients with asymptomatic CHF. CONCLUSIONS: CEA can be performed safely in patients with CHF. Using LRA is associated with a decreased incidence of perioperative cardiac complications in patients with symptomatic HF undergoing CEA.

Association between heart failure and arteriovenous access patency in patients with end-stage renal disease on hemodialysis.

BACKGROUND: Heart disease and chronic kidney disease are often comorbid conditions owing to shared risk factors, including diabetes and hypertension. However, the effect of congestive heart failure (CHF) on arteriovenous fistula (AVF) and AV graft (AVG) patency rates is poorly understood. We hypothesize preexisting HF may diminish blood flow to the developing AVF and worsen patency. METHODS: We conducted a single-institution retrospective review of 412 patients with end-stage renal disease who underwent hemodialysis access creation from 2015 to 2021. Patients were stratified based on presence of preexisting CHF, defined as clinical symptoms plus evidence of reduced left ventricular ejection fraction (EF) (<50%) or diastolic dysfunction on preoperative echocardiography. Baseline demographics, preoperative measures of cardiac function, and dialysis access-related surgical history were collected. Kaplan-Meier time-to-event analyses were performed for primary patency, primary-assisted patency, and secondary patency using standard definitions for patency from the literature. We assessed differences in patency for patients with CHF vs patients without CHF, patients with a reduced vs a normal EF, and AVG vs AVF in patients with CHF. RESULTS: We included 204 patients (50%) with preexisting CHF with confirmatory echocardiography. Patients with CHF were more likely to be male and have comorbidities including, diabetes, chronic obstructive pulmonary disease, hypertension, and a history of cerebrovascular accident. The groups were not significantly different in terms of prior fistula history (P = .99), body mass index (P = .74), or type of hemodialysis access created (P = .54). There was no statistically significant difference in primary patency, primary-assisted patency, or secondary patency over time in the CHF vs non-CHF group (log-rank P > .05 for all three patency measures). When stratified by preoperative left ventricular EF, patients with an EF of <50% had lower primary (38% vs 51% at 1 year), primary-assisted (76% vs 82% at 1 year), and secondary patency (86% vs 93% at 1 year) rates than those with a normal EF. Difference reached significance for secondary patency only (log-rank P = .029). AVG patency was compared against AVF patency within the CHF subgroup, with significantly lower primary-assisted (39% vs 87% at 1 year) and secondary (62% vs 95%) patency rates for AVG (P < .0001 for both). CONCLUSIONS: In this 7-year experience of hemodialysis access creation, reduced EF is associated with lower secondary patency. Preoperative CHF (including HF with reduced EF and HF with preserved EF together) is not associated with significant differences in overall hemodialysis access patency rates over time, but patients with CHF who receive AVG have markedly worse patency than those who receive AVF. For patients with end-stage renal disease and CHF, the risks and benefits must be carefully weighed, particularly for those with low EF or lack of a suitable vein for fistula creation.

Folate in the United States Population and its Association with Congestive Heart Failure.

Background: To investigate the relationship between red blood cell (RBC) folate and congestive heart failure (CHF). Methods: We extracted the concentrations of RBC folate and collated CHF information from the National Health and Nutrition Examination Survey (NHANES) survey (12820 individuals). Weighted univariate logistic regression, weighted multivariate logistic regression, and restrictive cubic spline (RCS) were used to assess the relationship between RBC folate concentrations and CHF. Results: The unadjusted model showed that the highest tertile group of RBC folate concentration was significantly associated with a higher risk of CHF compared to the lowest tertile group of RBC folate levels (odds ratio [OR] = 3.09; 95% confidence interval [CI], 2.14-4.46). Similar trends were seen in the multivariate-adjusted analysis (OR = 1.98; 95% CI: 1.27-3.09). The OR was > 1.0 when the predicted RBC folate exceeded 2757 nmol/L in the RCS model, indicating that the risk of CHF was low and relatively stable up to a predicted RBC folate level of 2757 nmol/L, but began to increase rapidly thereafter (p = 0.001). Conclusions: The risk of CHF may be increased either by high RBC folate concentrations (highest tertile of RBC folate or > 2637 nmol/L) or by folate deficiency. Considering the two sides of the association between RBC folate and CHF, there is a need for large-scale clinical research to better investigate if the association between RBC folate and CHF is a cause-effect relationship, what are the underlying pathophysiological basis, as well as to identify optimal dietary folate equivalent (DFE) and RBC folate concentration intervals.

The association between serum testosterone level and congestive heart failure in US male adults: data from National Health and Nutrition Examination Survey (NHANES) 2011-2016.

BACKGROUND: This study aimed to investigate the relationship between serum testosterone levels and the risk of congestive heart failure (CHF) in adult males. Previous research has suggested a potential link between serum testosterone and cardiovascular health, but the findings have been inconclusive. METHODS: This study was cross-sectional, and the data were obtained from the 2011-2016 cycle of the National Health and Nutrition Examination Survey (NHANES), which included a sample of 6,841 male participants. Serum testosterone levels were measured using a standardized assay, and CHF status was assessed through self-reporting. Covariates such as age, ethnicity, lifestyle factors, and health conditions were considered in the analysis. RESULTS: Among the participants, 242 individuals had a documented history of CHF. We observed a linear correlation between serum testosterone levels and CHF occurrence, with higher serum testosterone levels associated with a decreased risk of CHF (Q4 vs. Q1, OR = 0.29, 95% CI: 0.19-0.47, P < 0.001). After adjusting for confounding variables, multivariate analysis revealed that high serum testosterone levels remained significantly associated with a lower risk of CHF (OR: 0.47, 95% CI: 0.27-0.80, P = 0.01). Subgroup analysis indicated a significant association between high serum testosterone levels and reduced CHF risk in individuals over 50 years old. CONCLUSION: Our findings suggest that the serum testosterone level was positively associated with CHF in adult males. This study highlights the potential role of serum testosterone in cardiovascular health, particularly in older individuals. Further research is needed to elucidate the underlying mechanisms and explore the clinical implications of these findings.

Timing of Worsening Renal Function in Patients Hospitalized for Heart Failure Exacerbation Who Were Being Treated With Intravenous Diuretic Therapy.

BACKGROUND: This retrospective observational study investigated the incidence of worsening renal function (WRF) in patients hospitalized for heart failure (HF) and treated with intravenous diuretics in Japan. METHODS AND RESULTS: Associations between WRF at any point and HF treatments, and the effects of WRF on outcomes were evaluated (Diagnosis Procedure Combination database). Of 1,788 patients analyzed (mean [±SD] age 80.5±10.2 years; 54.4% male), 641 (35.9%) had WRF during a course of hospitalization for worsening HF: 208 (32.4%) presented with WRF before admission (BA-WRF; estimated glomerular filtration rate decreased by ≥25% from baseline at least once between 30 days prior to admission and admission); 44 (6.9%) had WRF that persisted before and after admission (P-WRF); and 389 (60.7%) had WRF develop after admission (AA-WRF). Delayed initial diuretic administration, higher maximum doses of intravenous diuretics during hospitalization, and diuretic readministration during hospitalization were associated with a significantly higher incidence of AA-WRF. Patients with WRF at any time point were at higher risk of death during hospitalization compared with patients without WRF, with adjusted hazard ratios of 3.56 (95% confidence interval [CI] 2.23-5.69) for BA-WRF, 3.23 (95% CI 2.21-4.71) for AA-WRF, and 13.16 (95% CI 8.19-21.15) for P-WRF (all P<0.0001). CONCLUSIONS: Forty percent of WRF occurred before admission for acute HF; there was no difference in mortality between patients with BA-WRF and AA-WRF.

Iron metabolism biomarkers and mortality risk in U.S. patients with congestive heart failure: NHANES 1999-2018 analysis.

BACKGROUND AND AIMS: Iron deficiency is a major public health concern. We aimed to assess the predictive capability of 4 iron metabolism biomarkers for all-cause and cardiovascular disease-specific mortality in U.S. patients with congestive heart failure (CHF). METHODS AND RESULTS: 1904 CHF patients aged ≥20 years were enrolled from NHANES, 1999-2000 to 2017-2018. All analyses were weighted to provide nationally representative estimates. Among 1905 CHF patients, mean age was 71 years, and 1024 (53.8%), 459 (24.1%), 206 (10.8%), and 216 (11.3%) were Non-Hispanic Black, Non-Hispanic White, Hispanic-Mexican American, and Hispanic-Other Hispanic, respectively. During follow-ups, 1080 deaths occurred. Median follow-up time was 5.08 years. Per-unit increase in natural-logarithmic-transformed iron and transferrin saturation decreased all-cause mortality risk separately by 33.0% (adjusted hazard ratio: 0.670, 95% confidence interval: 0.563 to 0.797, P < 0.001) and 32.6% (0.674, 0.495 to 0.917, 0.013), and per-unit increase in transferrin receptor increased mortality risk by 33.7% (1.337, 1.104 to 1.618, 0.004). Two derivates from 3 significant iron biomarkers were generated - transferrin receptor to natural-logarithmic-transformed iron ratio (TRI) and transferrin receptor to natural-logarithmic-transformed transferrin saturation ratio (TRTS), which were significantly associated with all-cause mortality, with per-unit increase corresponding to 2.692- and 1.655-fold increased all-cause mortality risk (P: 0.003 and 0.023). Only iron and TRTS were associated with the significant risk of cardiovascular disease-specific mortality (P: 0.004 and 0.017). CONCLUSIONS: Our findings identified 3 iron metabolism biomarkers that were individually, significantly, and independently associated with all-cause mortality in patients with CHF, and importantly 2 derivates generated exhibited stronger predictive capability.

The association of blood urea nitrogen to serum albumin ratio with short-term outcomes in Chinese patients with congestive heart failure: A retrospective cohort study.

BACKGROUND AND AIMS: Limited evidence exists on the prognostic outcomes of the blood urea nitrogen to serum albumin ratio (B/A ratio) in congestive heart failure (CHF), particularly in developing countries with scarce heart failure epidemiological data. We aimed to investigate the association between B/A ratio and short-term outcomes in Chinese patients with CHF. METHODS AND RESULTS: We included 1761 CHF patients with available B/A ratio data from a cohort of 2008 patients. Patients were categorized into three groups based on B/A ratio (low to high). The primary endpoint was death or readmission within 28 days, and the secondary endpoint was death or readmission within 90 days. We employed restricted cubic spline analysis, Cox proportional hazards regression, and Kaplan-Meier curves to evaluate the relationship between B/A ratio at admission and the endpoints. Even after adjusting for other variables, higher B/A ratios were associated with increased rates of 28 days and 90 days mortality or readmission (HR: 2.4, 95% CI: 1.81-3.18 and HR: 1.74, 95% CI: 1.48-2.05). Significant differences in the risks of both primary and secondary endpoints were observed among the three B/A ratio groups. The association between B/A ratio and CHF was stable in the different subgroups (all P for interaction＞0.05). CONCLUSION: Higher B/A ratios are associated with an increased risk of short-term mortality or readmission in Chinese patients with CHF. The B/A ratio shows promise as a prognostic indicator for short-term outcomes in CHF patients.

The impact of discharge letter content on unplanned hospital readmissions within 30 and 90 days in older adults with chronic illness - a mixed methods study.

BACKGROUND: Care transitions are high-risk processes, especially for people with complex or chronic illness. Discharge letters are an opportunity to provide written information to improve patients' self-management after discharge. The aim of this study is to determine the impact of discharge letter content on unplanned hospital readmissions and self-rated quality of care transitions among patients 60 years of age or older with chronic illness. METHODS: The study had a convergent mixed methods design. Patients with chronic obstructive pulmonary disease or congestive heart failure were recruited from two hospitals in Region Stockholm if they were living at home and Swedish-speaking. Patients with dementia or cognitive impairment, or a "do not resuscitate" statement in their medical record were excluded. Discharge letters from 136 patients recruited to a randomised controlled trial were coded using an assessment matrix and deductive content analysis. The assessment matrix was based on a literature review performed to identify key elements in discharge letters that facilitate a safe care transition to home. The coded key elements were transformed into a quantitative variable of "SAFE-D score". Bivariate correlations between SAFE-D score and quality of care transition as well as unplanned readmissions within 30 and 90 days were calculated. Lastly, a multivariable Cox proportional hazards model was used to investigate associations between SAFE-D score and time to readmission. RESULTS: All discharge letters contained at least five of eleven key elements. In less than two per cent of the discharge letters, all eleven key elements were present. Neither SAFE-D score, nor single key elements correlated with 30-day or 90-day readmission rate. SAFE-D score was not associated with time to readmission when adjusted for a range of patient characteristics and self-rated quality of care transitions. CONCLUSIONS: While written summaries play a role, they may not be sufficient on their own to ensure safe care transitions and effective self-care management post-discharge.

Clinical Presentation and Therapy of Ventricular Septal Defect.

Ventricular septal defects (VSDs) occur in 1.5-3.5 of 1000 live births and constitutes 20 % of congenital cardiac defects. There is no gender predominance.

Impact of Sex in the Incidence of Heart Failure in Patients with Chronic Coronary Syndrome.

PURPOSE OF REVIEW: This review examines the available evidence concerning the incidence of heart failure in patients with chronic coronary syndrome, with a focus on gender differences. RECENT FINDINGS: The incidence of heart failure in the context of chronic coronary syndrome presents conflicting data. Most of the available information stems from studies involving stable patients' post-acute coronary syndrome, revealing a wide range of incidence rates, from less than 3% to over 20%, observed over 5 years of follow-up. Regarding the gender differences in heart failure incidence, there is no consensus about whether women exhibit a higher incidence, particularly in the presence of evidence of obstructive coronary artery disease. However, in cases where obstructive coronary artery disease is absent, women may face a more unfavourable prognosis due to a higher prevalence of microvascular disease and heart failure with preserved ventricular function. The different profile of ischaemic heart disease in women difficult to establish differences in prognosis independently associated with female sex. Targeted investigations are essential to discern the incidence of heart failure in chronic coronary syndrome and explore potential gender-specific associations.

End-stage heart failure in congenitally corrected transposition of the great arteries: a multicentre study.

BACKGROUND AND AIMS: For patients with congenitally corrected transposition of the great arteries (ccTGA), factors associated with progression to end-stage congestive heart failure (CHF) remain largely unclear. METHODS: This multicentre, retrospective cohort study included adults with ccTGA seen at a congenital heart disease centre. Clinical data from initial and most recent visits were obtained. The composite primary outcome was mechanical circulatory support, heart transplantation, or death. RESULTS: From 558 patients (48% female, age at first visit 36 ± 14.2 years, median follow-up 8.7 years), the event rate of the primary outcome was 15.4 per 1000 person-years (11 mechanical circulatory support implantations, 12 transplantations, and 52 deaths). Patients experiencing the primary outcome were older and more likely to have a history of atrial arrhythmia. The primary outcome was highest in those with both moderate/severe right ventricular (RV) dysfunction and tricuspid regurgitation (n = 110, 31 events) and uncommon in those with mild/less RV dysfunction and tricuspid regurgitation (n = 181, 13 events, P < .001). Outcomes were not different based on anatomic complexity and history of tricuspid valve surgery or of subpulmonic obstruction. New CHF admission or ventricular arrhythmia was associated with the primary outcome. Individuals who underwent childhood surgery had more adverse outcomes than age- and sex-matched controls. Multivariable Cox regression analysis identified older age, prior CHF admission, and severe RV dysfunction as independent predictors for the primary outcome. CONCLUSIONS: Patients with ccTGA have variable deterioration to end-stage heart failure or death over time, commonly between their fifth and sixth decades. Predictors include arrhythmic and CHF events and severe RV dysfunction but not anatomy or need for tricuspid valve surgery.

Machine learning algorithm for predict the in-hospital mortality in critically ill patients with congestive heart failure combined with chronic kidney disease.

BACKGROUND: The objective of this study was to develop and validate a machine learning (ML) model for predict in-hospital mortality among critically ill patients with congestive heart failure (CHF) combined with chronic kidney disease (CKD). METHODS: After employing least absolute shrinkage and selection operator regression for feature selection, six distinct methodologies were employed in the construction of the model. The selection of the optimal model was based on the area under the curve (AUC). Furthermore, the interpretation of the chosen model was facilitated through the utilization of SHapley Additive exPlanation (SHAP) values and the Local Interpretable Model-Agnostic Explanations (LIME) algorithm. RESULTS: This study collected data and enrolled 5041 patients on CHF combined with CKD from 2008 to 2019, utilizing the Medical Information Mart for Intensive Care Unit. After selection, 22 of the 47 variables collected post-intensive care unit admission were identified as mortality-associated and subsequently utilized in the development of ML models. Among the six models generated, the eXtreme Gradient Boosting (XGBoost) model demonstrated the highest AUC at 0.837. Notably, the SHAP values highlighted the sequential organ failure assessment score, age, simplified acute physiology score II, and urine output as the four most influential variables in the XGBoost model. In addition, the LIME algorithm explains the individualized predictions. CONCLUSIONS: In conclusion, our study accomplished the successful development and validation of ML models for predicting in-hospital mortality in critically ill patients with CHF combined with CKD. Notably, the XGBoost model emerged as the most efficacious among all the ML models employed.

MEMS Technology in Cardiology: Advancements and Applications in Heart Failure Management Focusing on the CardioMEMS Device.

Heart failure (HF) is a complex clinical syndrome associated with significant morbidity, mortality, and healthcare costs. It is characterized by various structural and/or functional abnormalities of the heart, resulting in elevated intracardiac pressure and/or inadequate cardiac output at rest and/or during exercise. These dysfunctions can originate from a variety of conditions, including coronary artery disease, hypertension, cardiomyopathies, heart valve disorders, arrhythmias, and other lifestyle or systemic factors. Identifying the underlying cause is crucial for detecting reversible or treatable forms of HF. Recent epidemiological studies indicate that there has not been an increase in the incidence of the disease. Instead, patients seem to experience a chronic trajectory marked by frequent hospitalizations and stagnant mortality rates. Managing these patients requires a multidisciplinary approach that focuses on preventing disease progression, controlling symptoms, and preventing acute decompensations. In the outpatient setting, patient self-care plays a vital role in achieving these goals. This involves implementing necessary lifestyle changes and promptly recognizing symptoms/signs such as dyspnea, lower limb edema, or unexpected weight gain over a few days, to alert the healthcare team for evaluation of medication adjustments. Traditional methods of HF monitoring, such as symptom assessment and periodic clinic visits, may not capture subtle changes in hemodynamics. Sensor-based technologies offer a promising solution for remote monitoring of HF patients, enabling early detection of fluid overload and optimization of medical therapy. In this review, we provide an overview of the CardioMEMS device, a novel sensor-based system for pulmonary artery pressure monitoring in HF patients. We discuss the technical aspects, clinical evidence, and future directions of CardioMEMS in HF management.

If not angioedema, what is it? Diagnostic approach to facial edema.

Facial edema is a relatively frequent clinical presentation encountered in patients seen in allergology and dermatology clinics. The differential diagnosis is broad, and sometimes the definitive diagnosis can be a challenge for the clinician. Facial angioedema itself encompasses different etiopathologies (histaminergic, bradykinergic, etc.) that must be distinguished from other causes of facial edema, such as allergic contact dermatitis, granulomatous conditions, inflammatory causes, infections, neoplasms or paraneoplastic syndromes, autoimmune diseases, among other entities hereby referred as miscellanea. A proper diagnostic approach is essential to order the appropriate tests, as well as to prescribe a targeted treatment. This review focuses on entities that present with facial edema and summarize their characteristic clinical features.

The association of congestive heart failure on in-hospital lengths of stay, morbidity, and financial burden following primary total knee arthroplasty.

BACKGROUND: Current literature states that 6.2 million adults in the United States are living with heart failure. Studies investigating the impact of congestive heart failure (CHF) following primary total knee arthroplasty (TKA) are scarce. Hence, this research aimed to investigate whether individuals with congestive heart failure (CHF) undergoing primary total knee arthroplasty (TKA) experience: (1) longer durations of in-hospital stay; (2) increased incidences of health complications; and (3) a higher financial load. METHODS: A retrospective query using the 100% Parts A and B of the Medicare claims was performed. Cohorts of interest were identified using International Classification of Disease, Ninth Revision (ICD-9) and Current Procedural Terminology. Inclusion criteria for the study group consisted of patients with CHF undergoing primary TKA, whereas patients without CHF undergoing primary TKA served as the comparison cohort. RESULTS: The query yielded 1,101,169 patients (CHF = 183,540; case-matched = 917,629). Patients with CHF had longer in-hospital LOS (5- vs. 4-days) and a higher incidence and odds of developing 90-day medical complications (49.22% vs. 7.45%) following primary TKA. CHF patients incurred higher day of surgery and total global ninety-day episode of care costs compared to their matched counterparts. CONCLUSION: This study illustrated those patients with preexisting CHF undergoing a primary TKA have longer in-hospital lengths of stay and higher rates of morbidity and financial burden. With the increasing prevalence of CHF worldwide, orthopedists and other healthcare professionals can utilize the information provided in this study to educate patients and establish comprehensive treatment plans to help mitigate postoperative effects associated with CHF.
