Heyde Syndrome as Cause of New-onset Heart Failure in the Setting of Bioprosthetic Aortic Valve: A Case Report

This report describes the case of a 70-year-old female with a history of bioprosthetic aortic valve replacement. She presented to the emergency department with significant shortness of breath and bilateral lower extremity edema, which was found to be secondary to new-onset acute symptomatic congestive heart failure in the setting of Heyde syndrome.

Evaluation of a New Telemedicine System for Early Detection of Cardiac Instability in Patients With Chronic Heart Failure: Real-Life Out-of-Hospital Study.

For a decade, despite results from many studies, telemedicine systems have suffered from a lack of recommendations for chronic heart failure (CHF) care because of variable study results. Another limitation is the hospital-based architecture of most telemedicine systems. Some systems use an algorithm based on daily weight, transcutaneous oxygen measurement, and heart rate to detect and treat acute heart failure (AHF) in patients with CHF as early on as possible. The aim of this study is to determine the efficacy of a telemonitoring system in detecting clinical destabilization in real-life settings (out-of-hospital management) without generating too many false positive alerts. All patients self-monitoring at home using the system after a congestive AHF event treated at a cardiology clinic in France between March 2020 and March 2021 with at least 75% compliance on daily measurements were included retrospectively. New-onset AHF was defined by the presence of at least 1 of the following criteria: transcutaneous oxygen saturation loss, defined as a transcutaneous oxygen measurement under 90%; rise of cardiac frequency above 110 beats per minute; weight gain of at least 2 kg; and symptoms of congestive AHF, described over the phone. An AHF alert was generated when the criteria reached our definition of new-onset acute congestive heart failure (HF). A total of 111 consecutive patients (n=70 men) with a median age of 76.60 (IQR 69.5-83.4) years receiving the telemonitoring system were included. Thirty-nine patients (35.1%) reached the HF warning level, and 28 patients (25%) had confirmed HF destabilization during follow-up. No patient had AHF without being detected by the telemonitoring system. Among incorrect AHF alerts (n=11), 5 patients (45%) had taken inaccurate measurements, 3 patients (27%) had supraventricular arrhythmia, 1 patient (9%) had a pulmonary bacterial infection, and 1 patient (9%) contracted COVID-19. A weight gain of at least 2 kg within 4 days was significantly associated with a correct AHF alert (P=.004), and a heart rate of more than 110 beats per minute was more significantly associated with an incorrect AHF alert (P=.007). This single-center study highlighted the efficacy of the telemedicine system in detecting and quickly treating cardiac instability complicating the course of CHF by detecting new-onset AHF as well as supraventricular arrhythmia, thus helping cardiologists provide better follow-up to ambulatory patients.

Association of Anthracycline With Heart Failure in Patients Treated for Breast Cancer or Lymphoma, 1985-2010

Anthracyclines increase the risk for congestive heart failure (CHF); however, long-term cumulative incidence and risk factors for CHF after anthracycline therapy are not well defined in population-based studies. To compare the long-term cumulative incidence of CHF in patients with breast cancer or lymphoma treated with anthracycline therapy compared with healthy controls from the same community. This retrospective population-based case-control study included data from the Rochester Epidemiology Project. Participants included residents of Olmsted County, Minnesota, diagnosed with breast cancer or lymphoma from January 1985 through December 2010 matched for age, sex, and comorbidities with healthy controls, with a final ratio of 1 case to 1.5 controls. Statistical analysis was performed between July 2017 and February 2022. Cancer treatment and CHF risk factors. The main outcome was new-onset CHF, as defined by the modified Framingham criteria. Cox proportional hazards regression was used to estimate hazard ratios (HRs) to compare the risk of CHF in participants with cancer vs controls, adjusted for age, sex, diabetes, hypertension, hyperlipidemia, coronary artery disease, obesity, and smoking history. A total of 2196 individuals were included, with 812 patients with cancer and 1384 participants without cancer. The mean (SD) age was 52.62 (14.56) years and 1704 participants (78%) were female. Median (IQR) follow-up was 8.6 (5.2-13.4) years in the case group vs 12.5 (8.7-17.5) years in the control group. Overall, patients with cancer had higher risk of CHF compared with the control cohort even after adjusting for age, sex, diabetes, hypertension, coronary artery disease, hyperlipidemia, obesity, and smoking status (HR, 2.86 [95% CI, 1.90-4.32]; P < .001). After adjusting for the same variables, CHF risk was greater for patients with cancer receiving anthracycline (HR, 3.25 [95% CI, 2.11-5.00]; P < .001) and was attenuated and lost statistical significance for patients with cancer not receiving anthracyclines (HR, 1.78 [95% CI, 0.83-3.81]; P = .14). Higher cumulative incidence for patients treated with anthracyclines vs comparator cohort was observed at 1 year (1.81% vs 0.09%), 5 years (2.91% vs 0.79%), 10 years (5.36% vs 1.74%), 15 years (7.42% vs 3.18%), and 20 years (10.75% vs 4.98%) (P < .001). There were no significant differences in risk of CHF for patients receiving anthracycline at a dose of less than 180 mg/m2 compared with those at a dose of 180 to 250 mg/m2 (HR, 0.54 [95% CI, 0.19-1.51]) or at a dose of more than 250 mg/m2 (HR, 1.23 [95% CI, 0.52-2.91]). At diagnosis, age was an independent risk factor associated with CHF (HR per 10 years, 2.77 [95% CI, 1.99-3.86]; P < .001). In this retrospective population-based case-control study, anthracyclines were associated with an increased risk of CHF early during follow-up, and the increased risk persisted over time. The cumulative incidence of CHF in patients with breast cancer or lymphoma treated with anthracyclines at 15 years was more than 2-fold that of the control group.

Radiomics-based machine learning models in STEMI: a promising tool for the prediction of major adverse cardiac events.

To evaluate the potential value of the machine learning (ML) models using radiomic features of late gadolinium enhancement (LGE) and cine images on magnetic resonance imaging (MRI) along with relevant clinical information and conventional MRI parameters for the prediction of major adverse cardiac events (MACE) in ST-segment elevation myocardial infarction (STEMI) patients. This retrospective study included 60 patients with the first STEMI. MACE consisted of new-onset congestive heart failure, ventricular arrhythmia, and cardiac death. Radiomic features were extracted from cine and LGE images. Inter-class correlation coefficients (ICCs) were calculated to assess inter-observer reproducibility. LASSO (least absolute shrinkage and selection operator) method was used for radiomic feature selection. Seven separate models using a different combination of the available information were investigated. Classifications with repeat random sampling were done using adaptive boosting, k-nearest neighbor, naive Bayes, neural network, random forest, stochastic gradient descent, and support vector machine algorithms. Of the 1748 extracted radiomic features, 1393 showed good inter-observer agreement. With LASSO, 25 features were selected. Among the ML algorithms, the neural network showed the highest predictive performance on average (area under the curve (AUC) 0.822 ± 0.181). Of the best-calculated model, the one using clinical parameters, CMRI parameters, and selected radiomic features (model 7), the diagnostic performance was as follows: 0.965 AUC, 0.894 classification accuracy, 0.906 sensitivity, 0.883 specificity, 0.875 positive predictive value (PPV), and 0.912 negative predictive value (NPV). The radiomics-based ML models incorporating clinical and conventional MRI parameters are promising for predicting MACE occurrence in STEMI patients in the follow-up period. • Acute coronary occlusion results in variable changes at the cellular level ranging from myocyte swelling to myonecrosis depending on the duration of the ischemia and the metabolic state of the heart, which causes subtle heterogeneous signal changes that are imperceptible to the human eye with cardiac MRI. • Radiomics-based machine learning analysis of cardiac MR images is promising for risk prediction. • Combining MRI-derived parameters and clinical variables increases the accuracy of predictive models.

382: EHRLICHIOSIS-INDUCED MYOCARDITIS

Introduction: Myocarditis caused by Ehrlichiosis is a rare manifestation. The following case emphasizes the significance of early detection and its treatment. Description: A previously healthy 77-year-old female presented with a two-day history of generalized weakness and altered mental status. On arrival, she had a fever of 101.5°F, a heart rate of 110 beats per minute, a respiratory rate of 26 breaths per minute, a blood pressure of 80/70 mmHg, and an oxygen saturation of 92% on low-flow nasal cannula oxygen therapy. She was disoriented without a focal neurologic deficit, and the remainder of the examination was unremarkable. Laboratory evaluation revealed leukocytosis at 22000 /mm3, thrombocytopenia at 34000 /mm3, troponins at 6300 ng/mL, creatinine of 3.0 mg/dL, and mild transaminitis. Her hepatitis panel, toxicology screen, urine, and blood cultures were negative. A lumbar puncture was not performed because of thrombocytopenia. Her pan-computed tomography (CT) scans were also unremarkable. Echocardiography revealed severe diffuse hypokinesia with a left ventricle ejection fraction of 20%. Cardiac catheterization was deferred due to renal dysfunction. Her empiric antibiotics regimen was de-escalated to doxycycline after peripheral smear, and a PCR test confirmed Ehrlichiosis. Her symptoms improved, and she was discharged to inpatient rehabilitation. An echocardiogram in 6 months showed an improved ejection fraction of 45%. Discussion: Ehrlichiosis usually manifests with symptoms of fever, myalgias, and malaise mimicking influenza-like illness. However, severe sequelae are more traditionally encountered at extreme ages. Myocarditis is a rare and fatal occurrence. The pathogenic mechanism driving cardiac involvement is still partially understood. It may cause cardiac damage or produce immunosuppression and inflammatory cell dysfunction, leading to nonspecific myocyte damage. We believe our patient had ehrlichiosis-related myocarditis, as evidenced by peripheral smear testing, profoundly raised cardiac enzymes, new-onset congestive heart failure, and recovery of cardiac function after treatment. In endemic locations, especially during the summer, it is prudent to keep suspicion of ehrlichiosis-associated myocarditis.

Incidence, Mortality, and Imaging Outcomes of Atrial Arrhythmias in COVID-19

Atrial arrhythmias (AAs) are common in hospitalized patients with COVID-19; however, it remains uncertain if AAs are a poor prognostic factor in SARS-CoV-2 infection. In this retrospective cohort study from 2014 to 2021, we report in-hospital mortality in patients with new-onset AA and history of AA. The incidence of new-onset congestive heart failure (CHF), hospital length of stay and readmission rate, intensive care unit admission, arterial and venous thromboembolism, and imaging outcomes were also analyzed. We further compared the clinical outcomes with a propensity-matched influenza cohort. Generalized linear regression was performed to identify the association of AA with mortality and other outcomes, relative to those without an AA diagnosis. Predictors of new-onset AA were also modeled. A total of 6,927 patients with COVID-19 were included (626 with new-onset AA, 779 with history of AA). We found that history of AA (adjusted relative risk [aRR] 1.38, confidence interval [CI], 1.11 to 1.71, p = 0.003) and new-onset AA (aRR 2.02, 95% CI 1.68 to 2.43, p <0.001) were independent predictors of in-hospital mortality. The incidence of new-onset CHF was 6.3% in history of AA (odds ratio 1.91, 95% CI 1.30 to 2.79, p <0.001) and 11.3% in new-onset AA (odds ratio 4.01, 95% CI 3.00 to 5.35, p <0.001). New-onset AA was shown to be associated with worse clinical outcomes within the propensity-matched COVID-19 and influenza cohorts. The risk of new-onset AA was higher in patients with COVID-19 than influenza (aRR 2.02, 95% CI 1.76 to 2.32, p <0.0001), but mortality associated with new-onset AA was higher in influenza (aRR 12.58, 95% CI 4.27 to 37.06, p <0.0001) than COVID-19 (aRR 1.86, 95% CI 1.55 to 2.22, p <0.0001). In a subset of the patients with COVID-19 for which echocardiographic data were captured, abnormalities were common, including valvular abnormalities (40.9%), right ventricular dilation (29.6%), and elevated pulmonary artery systolic pressure (16.5%); although there was no evidence of a difference in incidence among the 3 groups. In conclusion, new-onset AAs are associated with poor clinical outcomes in patients with COVID-19.

Scleroderma hypertensive renal crisis among systemic sclerosis patients: A national emergency department database study.

Literature regarding trends for incidence and mortality of scleroderma renal crisis (SRC) in systemic sclerosis (SSc) within the United States (US) emergency departments (EDs) is limited. To study the mortality of SRC among SSc patient encounters within the US EDs. Data from the National Emergency Department Sample (NEDS) constitutes 20% sample of hospital-owned EDs and inpatient sample in the US were analyzed for SSc with and without SRC using ICD-9 codes. A linear p-trend was used to assess the trends. Of the total 180,435 encounters with the diagnosis of SSc in NEDS for the years 2009 2014, 771 or 4.27/1000 patients (mean age 59.6 ± 15.5 years, 75.4% females) were recorded with SRC. The numerical differences in mortality among SRC (32 or 4.1%) and non-SRC subgroups (5487 or 3.1%) did not reach statistical significance (p = 0.3). Major complications among SRC in comparison to non-SRC subgroup include ischemic stroke (5.6% vs 0.98%, p = 0.001), new-onset AF (8% vs 6.9%, p = 0.001), new-onset congestive heart failure (24.1% vs 8.8%, p = 0.001), pulmonary arterial hypertension (15.8% vs 10.9%, p = 0.001), respiratory failure (27.5% vs 10.5%, p = 0.001), and deep vein thrombosis (4.7% vs 4.6%, p = 0.001). Congestive heart failure (CHF) was strongly associated with SRC among SSc (OR 4.3 95%CI 2.7-6.7; p < 0.001). The absolute yearly rate of SRC had increased over the study years from 2.11/1000 to 5.79/1000 (linear p-trend 0.002) while the mortality trend remained steady. SRC is a relatively rare medical emergency. Although there has been a significant rise in the rate of SRC among SSc patients over the study years, mortality rates had remained steady. SSc patients with CHF should be considered to have low threshold for admission to inpatient services from EDs.

Increased Mortality in Hip Fracture Patients With Aortic Stenosis and Pulmonary Hypertension Compared to Aortic Stenosis Alone.

Hip fractures are one of the most common traumatic injuries in the United States, secondary to an aging population. Multiple comorbidities are found in patients who present to trauma centers (TCs) with isolated hip fractures (IHFs) including significant cardiac disease. Aortic stenosis (AS) among these patients has been recently shown to increase mortality. However, factors leading to death from AS are unknown. We hypothesize that pulmonary hypertension (PH) is a significant mechanism of death among IHF patients with AS. This is a multicenter retrospective cohort study examining IHF patients treated at Level I and II TCs within a large hospital system from 2015 to 2019. Patients who had IHFs and AS were compared to those who had IHFs, AS, and PH. Multivariable logistic regression was used to risk adjust by age, race, insurance status, and comorbidities. The primary outcome was inpatient mortality. The secondary outcomes were hospital-acquired complications. A total of 1388 IHF patients with AS were included in the study. Eleven percent of these patients also had PH. The crude mortality rate was higher if IHF patients had both AS and PH compared to IHF with AS alone (9% vs 3.7%, P-value .003). After risk adjustment, a higher risk of mortality was still significant (aOR 2.56 [95% CI 1.28, 5.11]). In addition, IHF patients with both AS and PH had higher complication rates; the exposure group had higher percentage of pulmonary embolism (1.4% vs .2%, adjusted P-value .03), new-onset congestive heart failure (4.1% vs 1%, adjusted P-value .01), and sepsis/septicemia (3.5% vs 1.4%, adjusted P-value .05). In patients with IHFs, PH and AS increase the likelihood of inpatient mortality by 2.5 times compared to AS alone. Pulmonary hypertension among IHF patients with AS is an important risk factor to identify in the preoperative period. Early identification may lead to better perioperative management and counseling of patients at higher risk of complications.

Development of a Risk Score for Cardiovascular Events in Anthracycline Treated DLBCL Patients

Introduction:There is increased risk of congestive heart failure (CHF) following anthracycline-based chemotherapy in patients with Diffuse Large B-cell lymphoma (DLBCL). Other than increased cumulative anthracycline dose, little is known about risk factors for developing CHF and other cardiovascular events (CVE).Methods:We conducted a retrospective analysis of 539 DLBCL patients diagnosed at University Hospitals Seidman Cancer Center between 2002 - 2016. Baseline patient and disease characteristics, patterns of treatment and outcomes after therapy, including response, survival, relapse, CVE, and causes of death were collected.Time-to-CVE was measured from the date of DLBCL diagnosis to the date of CVE diagnosis and censored at the date of last follow-up for those without CVE, considering death as competing risk. The cumulative incidence of CVE was estimated taking death as competing risk into account. Univariate and multivariable analysis on time-to-CVE was done using Gray's method. Multicollinearity was tested and some of the highly correlated covariables were excluded in the final analysis. CVE risk scores were computed for each patient as a linear combination of the factors included in the multivariable model and their respective coefficients. The optimal cutoff point was identified by searching the spectrum of the risk scores to have the best discrimination of time-to-CVE among patients at low/high risks. All tests were two-sided and p-value ≤ 0.05 were considered statistically significant.Results:We identified 463 patients who received anthracycline to be included in the statistical analysis. Baseline clinical and disease characteristics including comorbidities, clinical risk factors are outlined in Table 1.After a median follow up of 71.1 (range: 0.3 - 216.1) months, 5-year PFS was 59% with median PFS of 82.7 (95% Cl: 71.1 - 115.7) months and 5-year OS was 71% with median OS of 152.6 (95% CI: 127.5 - 162) months.CVE were identified in 92 patients (19.9%), with 128 events identified. The most common CVE was new onset of CHF in 10.4% of patients, followed by atrial fibrillation (4.9%) and asymptomatic heart failure ( 3%) (Table 2).The 3, 6 and 9-year cumulative incidence of CVE for early stage was 13.1%, 15.2% and 18.5%, respectively and 22.2%, 31.4% and 36.5% for advanced stage, respectively (p-value = 0.026). Similarly, the cumulative incidence of CVE was increased in patients with diabetes, with a 3-year cumulative incidence of CVE of 9.4% vs. 17.5% in patients with and without diabetes, respectively.Proportional hazards regression for time-to-CVE identified age >65 years, CD10 expression by IHC, diabetes, and hypertension as significant predictors of time-to-CVE on univariate analysis. On multivariable regression analysis with advanced age at diagnosis, stage, baseline lymphocyte count, and diabetes; stage was still significant in predicting time-to- CVE controlling the effects of advanced age and diabetes, which were also marginally significant.A predictive formula was created to help identify patients at highest risk for cumulative incidence of CVE. Using advanced age (over 65 years of age), baseline lymphocyte count above 800/µL, advanced stage at diagnosis and history of diabetes patients could be stratified into groups with low, intermediate and high risk for CVE (Table 4 and Figure 1).Risk score = Age >65 (3 points) + Lymphocyte count > 800/µL (-1 point) + Stage III/IV(8 points) + Diabetes (3 points) (Table 3)One-year cumulative incidence of CVE was 5.3% for low-risk patients, 7.9% for intermediate risk patients and 13.4% for high risk patients (Figure 1).Conclusions:Our analysis indicates a high risk of CVE in anthracycline treated DLBCL patients, with 19.9% of patients having a CVE in our cohort. The proposed CVE predictive score uses clinical and laboratory parameters routinely collected on all new DLBCL patients and can be easily assessed in the clinical setting. Patients in the high-risk group have a cumulative incidence of CVE of 13.4% at 1 year and would likely benefit from surveillance and interventions. Use of a clinical risk score can aid in the identification of patients at highest CVE risk to conduct studies of surveillance and prevention of this common complication.

Association of cytomegalovirus diseases with newly developed myocardial infarction and congestive heart failure: data from a national population-based cohort.

IntroductionAnti-cytomegalovirus (CMV) IgG seropositive and/or titer are associated with a higher risk of cardiovascular diseases (CVD). However, it is not clear whether CMV end-organ disease may have a relation with development of CVD or chronic heart diseases.Material and methodsIn matched cohort study, the National Health Insurance Database covering 50 million people was used to identify 667 patients with CMV diseases and aged ≥ 20 years between 2010 and 2014. 6,670 control subjects without CMV diseases were matched by age, sex, type 2 diabetes mellitus (DM), hypertension, dyslipidemia, and cohort entry year. Data on CMV disease and heart disease events of myocardial infarction (MI), congestive heart failure (CHF), and atrial fibrillation (AF) were retrieved. Previous events before CMV disease or cohort entry were excluded until January 2006. Subjects were followed until December 2015 in subjects without events and until date of events in subjects with events.ResultsThe multivariate regression model adjusted by age, sex, low-income status, type 2 DM, hypertension, dyslipidemia, solid organ transplantation, and hematopoietic stem cell transplantation showed a significantly higher incidence rate of MI (odds ratio (OR) = 2.1, 95% confidence intervals (CI): 1.0–4.5) and CHF (OR = 3.8, 95% CI: 2.1–6.8) but not AF (OR = 1.9, 95% CI: 0.9–4.0) in patients with CMV disease. The age group of 40–64 years with CMV disease had the highest risk for new-onset CHF in this regression model (OR = 9.4, 95% CI: 4.12–21.44, p = 0.029).ConclusionsSymptomatic CMV tissue-invasive diseases were associated with a higher risk of new-onset MI and CHF.

Proposed A2C2S2-VASc score for predicting atrial fibrillation development in patients with atrial flutter

Long-term observation of catheter ablation vs. pharmacotherapy in the management of persistent and long-standing persistent atrial fibrillation (CAPA study).

The roles of radiofrequency catheter ablation (RFCA) and pharmacotherapy in treating persistent and long-standing persistent atrial fibrillation (AF) have not been sufficiently investigated. We conducted a multicentre, randomized, controlled trial to compare the effects of RFCA and pharmacotherapy on the prognosis of these patients. A total of 648 patients with persistent and long-standing persistent AF were enrolled from 30 centres and randomized to either the ablation group (n = 327) or the pharmacotherapy group (n = 321). After 54.2 ± 10.6 months of follow-up, the primary endpoints occurred significantly more rarely in the ablation group than in the pharmacotherapy group (10.4% vs. 17.4%; hazard ratio 0.59, 95% confidence interval 0.48-0.75; P < 0.001). The incidence of stroke/transient ischaemic attack (TIA) was significantly lower in the ablation group (4.2% vs. 7.2%, P < 0.001). Likewise, the incidence of new-onset congestive heart failure (CHF) was lower in the ablation group (2.8% vs. 7.2%, P < 0.001). More patients had sinus rhythm in the ablation group than in the pharmacotherapy group (60.6% vs. 20.9%, P < 0.001), but fewer patients were on antiarrhythmic drugs (24.4% vs. 41.6%, P < 0.001) and warfarin (60.8% vs. 83.9%, P = 0.001). Both the 6-min walk distance and the quality of life (QoL) were improved in the ablation group at the end of follow-up. In patients with persistent and long-standing persistent AF, RFCA-based treatment was superior to pharmacotherapy in decreasing stroke/TIA and new-onset CHF and improving QoL.

Usefulness of H2FPEF score as an independent predictor of heart failure development in patients with atrial fibrillation

Abstract Background The H2 FPEF score, which based on simple clinical characteristics and echocardiography, enables discrimination of HFpEF from noncardiac causes of dyspnea. Purpose We sought to evaluate whether H2 FPEF score predicts congestive heart failure (CHF) development in patients with atrial fibrillation (AF). Methods Among adult AF patients who underwent transthoracic echocardiography between July 2007 and December 2008, those with preserved left ventricular ejection fraction (LVEF) (≥50%) were included and followed up to new-onset CHF events. Patients with a history of CHF, cardiac surgery, or significant left-sided valvular heart disease were excluded. The H2 FPEF score was calculated from 6 variables (obesity = 2 points, treatment with ≥2 antihypertensive drugs = 1 point, AF = 3 points, echocardiographic pulmonary artery systolic pressure &amp;gt;35 mmHg = 1 point, age &amp;gt;60 years = 1 point, and echocardiographic E/e'ratio &amp;gt;9 = 1 point). CHF was ascertained using Framingham criteria. Cox-proportional hazards modeling was used to assess risk of CHF development. Results Of 562 AF patients, 367 (69±10 year old, 66% men) met all study criteria. Of whom, 37 (10%) developed CHF events during a mean follow–up of 56±43 months. The mean H2 FPEF score was 5.50±1.14, and the number of patients with H2 FPEF score ≥7 was 64 (17%). After adjusting for comorbidities in a multivariate model, H2 FPEF score was significant predictor of new-onset CHF events both as continuous (HR=1.43, 95% CI: 1.05–1.96, P&amp;lt;0.05) or categorical (H2 FPEF score ≥7) (HR=2.32, 95% CI: 1.17–4.63, P&amp;lt;0.05) variables. The Kaplan-Meier estimates of CHF-free survival stratified by H2 FPEF status (≥7 or &amp;lt;7) were shown in Figure. Conclusion H2 FPEF score provides prognostic information for new-onset CHF development in patients with AF. Figure 1 Funding Acknowledgement Type of funding source: None

Utilization of regional versus general anesthesia and its impact on lower extremity bypass outcomes

ObjectivePrevious studies evaluating general anesthesia (GA) vs regional (epidural/spinal) anesthesia (RA) for infrainguinal bypass have produced conflicting results. The purpose of this study was to analyze the factors associated with contemporary use of RA and to determine whether it is associated with improved outcomes after infrainguinal bypass in patients with critical limb ischemia. MethodsUsing the Vascular Quality Initiative infrainguinal database, a retrospective review identified all critical limb ischemia patients who received an infrainguinal bypass from 2011 through 2016. Patients were then separated by GA or RA. Primary outcomes were perioperative mortality, complications, and length of stay. Predictive factors for RA and perioperative outcomes were analyzed using a mixed-effects model to adjust for center differences. ResultsThere were 16,052 patients identified to have a lower extremity bypass during this time frame with 572 (3.5%) receiving RA. There was a wide variation in the use of RA, with 31% of participating centers not using it at all. Age (67.2 vs 70.3 years; P < .001), chronic obstructive pulmonary disease (25.7% vs 30.9%; P < .001), and urgency of the operation (75.7% vs 80.4%; P = .01) were found to be independently associated with receiving a regional anesthetic. Univariate and multivariate analysis demonstrated that length of stay (6.8 days vs 5.7 days; P < .01), postoperative congestive heart failure (2.3% vs 1.1%; P = .040), and change in renal function (5.7% vs 2.9%; P = .005) were all significant outcomes in favor of RA. There was a trend toward lower mortality rates; however, this did not reach statistical significance. Rates of myocardial infarction, pulmonary complications, and stroke were not found to be statistically different. Coarsened exact matching continued to demonstrate a difference in length of stay and rates of new-onset congestive heart failure in favor of RA. ConclusionsRA is an infrequent but effective form of anesthesia for infrainguinal bypass surgery. Elderly patients and those with underlying respiratory problems may benefit from this form of anesthesia. Further evaluation within institutions should be performed to identify which patients would most benefit from RA or GA.

Congestive heart failure in older adults diagnosed with follicular lymphoma: A population-based study.

To the authors' knowledge, there is limited information regarding the long-term risk of congestive heart failure (CHF) among patients with follicular lymphoma, a prevalent non-Hodgkin lymphoma diagnosis among those aged >65 years, especially within the context of therapeutic exposures and preexisting comorbidities. Using Surveillance, Epidemiology, and End Results-Medicare data from 1999 through 2013, the authors identified 6109 patients with follicular lymphoma who were diagnosed at age ≥66 years between January 1, 2000 and December 31, 2011, and a frequency-matched Medicare noncancer sample. Subdistribution hazards models assessed risks associated with new-onset CHF through December 31, 2013. Propensity score-matched models examined CHF risk in patients receiving anthracyclines when compared with matched noncancer controls. When compared with matched controls, patients with follicular lymphoma receiving anthracyclines at ages 66 to 75 years had a 1.7-fold (95% confidence interval, 1.4-fold to 2.1-fold) higher risk of new-onset CHF; patients diagnosed at age >75 years did not differ from noncancer controls with regard to CHF risk. Preexisting hypertension was associated with a 1.7-fold and 1.35-fold, respectively, increased hazard of CHF for each age group, independent of anthracycline exposure. Preexisting diabetes was associated with 1.5-fold increased hazard of CHF only in those patients aged 66 to 75 years. Patients with new-onset CHF had a 18% lower 10-year survival compared with those without CHF. Patients with follicular lymphoma who were exposed to anthracyclines between the ages of 66 years and 75 years were found to be at an increased risk of new-onset CHF; preexisting hypertension and diabetes appeared to increase this risk. The findings of the current study support and inform the risk-based follow-up of vulnerable populations.

Icodextrin reduces the risk of congestive heart failure in peritoneal dialysis patients.

Icodextrin can enhance ultrafiltration and consequently improve fluid balance and can control blood pressure and reduce left ventricular mass for peritoneal dialysis (PD) patients. This study investigated whether icodextrin use could reduce the risk of congestive heart failure (CHF) for PD patients. From the Taiwan National Health Insurance database, we identified 5462 newly diagnosed end-stage renal disease patients undergoing PD from 2005 to 2010. Incidence rates and hazard ratio of CHF were estimated for patients with and without icodextrin treatment by the end of 2011. Among PD patients, icodextrin users had an overall 26% lower incidence of CHF than non-users (13.7 vs 18.6 per 1000 person-years). Relatively, the adjusted hazard ratio was 0.67 (95% CI=0.52-0.87) for users compared with non-users. Among PD patients with diabetes, the incident CHF in icodextrin users was 37.5% lower than that in non-users (17.8 vs 28.5 per 1000 person-years). Among PD patients without diabetes, the incident CHF in icodextrin users was 30.4% lower than that in non-users (11.0 vs 15.8 per 1000 person-years). Icodextrin solution could reduce the risk of new-onset CHF, particularly effective when diabetic PD patients use it.

New-Onset Cardiovascular Morbidity in Older Adults With Stage I to III Colorectal Cancer.

Purpose We sought to determine the long-term risk of cardiovascular disease (CVD)-stroke and myocardial infarction-and congestive heart failure (CHF) in older patients with colorectal cancer, as well as to understand the roles that preexisting comorbidities and cancer therapy play in increasing this risk. Patients and Methods We evaluated individuals from the SEER-Medicare database with incident stage I to III colorectal cancer at age older than 65 years between January 1, 2000, and December 31, 2011 (n = 72,408) and compared these patients with a matched cohort of Medicare patients without cancer (n = 72,408). Results Median age at diagnosis of colorectal cancer was 78 years (range, 66 years to 106 years), and median follow-up was 8 years since diagnosis. The 10-year cumulative incidence of new-onset CVD and CHF were 57.4% and 54.5% compared with 22% and 18% for control, respectively ( P < .001). The interaction between hypertension and chemotherapy was significant ( P < .001) for CVD, and that between diabetes and chemotherapy was significant ( P < .001) for CHF. Within the first 2 years since diagnosis, exposure to capecitabine alone increased CHF hazard (hazard ratio [HR], 3.6; 95% CI, 12.76 to 4.38) compared with exposure to fluorouracil alone. Conversely, patients who were treated with fluorouracil alone had a higher CVD hazard at < 2 years and > 2 years since diagnosis compared with patients who received capecitabine alone (< 2 years HR, 0.63; 95% CI, 0.53 to 0.75; > 2 years HR, 0.72; 95% CI, 0.62 to 0.84). Conclusion Older patients with colorectal cancer are at increased risk of developing CVD and CHF. Diabetes and hypertension interact with chemotherapy to increase the risk of cardiovascular morbidity. Future studies should assess the potential for personalized therapeutic options for those with preexisting morbidities and for structured monitoring for patients with a history of exposure to chemotherapy regimens, as well as explore the management of preexisting comorbidities to address long-term cardiovascular morbidity.

PR interval prolongation in coronary patients or risk equivalent: excess risk of ischemic stroke and vascular pathophysiological insights

BackgroundWhether PR prolongation independently predicts new-onset ischemic events of myocardial infarction and stroke was unclear. Underlying pathophysiological mechanisms of PR prolongation leading to adverse cardiovascular events were poorly understood. We investigated the role of PR prolongation in pathophysiologically-related adverse cardiovascular events and underlying mechanisms.MethodsWe prospectively investigated 597 high-risk cardiovascular outpatients (mean age 66 ± 11 yrs.; male 67%; coronary disease 55%, stroke 22%, diabetes 52%) for new-onset ischemic stroke, myocardial infarction (MI), congestive heart failure (CHF), and cardiovascular death. Vascular phenotype was determined by carotid intima-media thickness (IMT).ResultsPR prolongation >200 ms was present in 79 patients (13%) at baseline. PR prolongation >200 ms was associated with significantly higher mean carotid IMT (1.05 ± 0.37 mm vs 0.94 ± 0.28 mm, P = 0.010). After mean study period of 63 ± 11 months, increased PR interval significantly predicted new-onset ischemic stroke (P = 0.006), CHF (P = 0.040), cardiovascular death (P < 0.001), and combined cardiovascular endpoints (P < 0.001) at cut-off >200 ms. Using multivariable Cox regression, PR prolongation >200 ms independently predicted new-onset ischemic stroke (HR 8.6, 95% CI: 1.9–37.8, P = 0.005), cardiovascular death (HR 14.1, 95% CI: 3.8–51.4, P < 0.001) and combined cardiovascular endpoints (HR 2.4, 95% CI: 1.30–4.43, P = 0.005). PR interval predicts new-onset MI at the exploratory cut-off >162 ms (C-statistic 0.70, P = 0.001; HR: 8.0, 95% CI: 1.65–38.85, P = 0.010).ConclusionsPR prolongation strongly predicts new-onset ischemic stroke, MI, cardiovascular death, and combined cardiovascular endpoint including CHF in coronary patients or risk equivalent. Adverse vascular function may implicate an intermediate pathophysiological phenotype or mediating mechanism.

New-onset congestive heart failure (CHF) and cardiovascular disease (CVD) in older colorectal cancer (CRC) survivors: A population-based study.

10011 Background: CRC is primarily a disease of the elderly. The high burden of pre-existing comorbidities alone or in concert with cancer treatment place the older patients with CRC at increased risk of new-onset morbidities, specifically, CVD and CHF. However, the magnitude of risk of new-onset morbidity, and its association with pre-existing comorbidities or treatment remain unknown. Methods: Using SEER-Medicare data, we evaluated individuals diagnosed with incident stage I-III CRC at age ≥66y between 1/1/2000 and 12/31/2011 who had survived ≥2y after diagnosis (n = 57,256; 77% with colon cancer). We compared these to an age, sex-, and race-frequency matched comparison group of non-cancer Medicare patients (n = 104,731). We evaluated new-onset CHF and CVD using competing risk cumulative incidence functions and multivariable Cox regression models. Results: The median age at diagnosis was 77y (66-106y); 45% males; and 85% non-Hispanic white. Median follow-up was 8y (2-14y) from diagnosis of CRC. Treatment included surgery for 99%, chemotherapy for 31%, and radiation for 12%. New-onset morbidity: The 10y cumulative incidence of new-onset CHF and CVD were 43.6% and 58.9%, respectively. After controlling for pre-cancer comorbidities, CRC survivors were at increased risk of new-onset CHF (HR 1.29) and CVD (HR 1.74) (all p &lt; 0.001) compared to controls. Patients receiving radiation (HR 1.29) or 5-FU+oxaliplatin (HR 1.09) were at increased risk of CVD compared to those without those therapies (p &lt; 0.001). Pre-existing diabetes (HR 1.16) and CHF (HR 1.21) independently increased the risk of CVD (p &lt; 0.001). While 5FU+oxaliplatin did not increase the risk of CHF independently (HR 0.97), diabetic patients treated with 5-FU+oxaliplatin were at 1.71-fold increased risk of developing CHF (p &lt; 0.001) when compared with those without pre-existing diabetes. Conclusions: Older CRC survivors are at increased of developing CHF and CVD. Monitoring survivors with a history of exposure to 5FU+oxaliplatin or radiation, and improving management of pre-existing comorbidities may reduce the burden of long-term morbidity for older CRC survivors.
