ABSTRACTBackgroundIncidence of congestive heart failure is difficult to predict by standard methods. We have developed a method called the signal intensity coefficient that uses echocardiographic texture analysis to quantify microstructural changes which may occur in at-risk patients prior to development of a clinical heart failure syndrome.MethodsParticipants from the Framingham Offspring Cohort study who attended the 8th visit and received screening echocardiography were included. Participants were followed for a mean of 7.4 years for incident congestive heart failure. Cox proportional hazards modeling was used to assess the hazard ratio of signal intensity coefficient in the top quartile of values versus other quartiles in the total and sex-stratified population.Results2511 participants with interpretable echocardiography and no history of congestive heart failure, stroke, or myocardial infarction were included in this study. The top quartile signal intensity coefficient had a hazard ratio of 1.83 (p=0.0048) for incident heart failure. When additional clinical risk factors were added to the model, this became non-significant. Within women, an elevated hazard ratio was significant in multiple models including age and hypertensive medication use. Models were not significant in men.ConclusionsElevated signal intensity coefficient is associated with an increased risk of incident congestive heart failure. This trend remains significant in women after inclusion of age and hypertensive medication use. The signal intensity coefficient may be able to identify patients at risk of developing congestive heart failure using echocardiographic texture analysis.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has killed hundreds of thousands worldwide. Those with cardiovascular disease represent a vulnerable population with higher risk for contracting COVID-19 and worse prognosis with higher case fatality rates. Congestive heart failure (CHF) may lead to worsening COVID-19 symptoms. However, it is unclear if CHF is an independent risk factor for severe COVID-19 infection or if other accompanying comorbidities are responsible for the increased risk. Methods: From March to June 2020, data was obtained from adult patients diagnosed with COVID-19 infection who were admitted in the Rush University System for Health (RUSH) in Illinois. Heart failure patients, determined by ICD code assignments extracted from the electronic medical records, were identified. Multivariable logistic regression was performed between predictor variables and a composite outcome of severe infection consisting of Intensive Care Unit (ICU) admission, intubation, or in-hospital mortality. Results: In this cohort (n=1136), CHF [odds ratio (OR) 1.02] alone did not predict a more severe illness. Prior myocardial infarction [(MI), OR 3.55], history of atrial fibrillation [(AF), OR 2.14], and male sex (OR 1.55) were all significantly (p<0.001) associated with more severe COVID-19 illness course when controlling for CHF (Figure 1). In the 178 CHF patients, more advanced age (68.8 years vs. 63.8 years; p<0.05) and female sex (54.5% vs. 39.1%; p<0.05) were associated with increased severity of illness. Conclusions: Prior MI, history of AF, and male sex predicted more severe COVID-19 illness course in our cohort, but pre-existing heart failure alone did not. However, CHF patients who are females and older in age are at risk for severe infection. These findings help clinicians identify patients with comorbidities early at risk for severe COVID-19 illness.

Background: Carbon monoxide poisoning (COP) is an important public health issue around the world. It may increase the risk of myocardial injury, but the association between COP and congestive heart failure (CHF) remains unclear. We conducted a study incorporating data from epidemiological and animal studies to clarify this issue. Methods: Using the National Health Insurance Database of Taiwan, we identified patients with COP diagnosed between 1999 and 2012 and compared them with patients without COP (non-COP cohort) matched by age and the index date at a 1:3 ratio. The comparison for the risk of CHF between the COP and non-COP cohorts was made using Cox proportional hazards regression. We also established a rat model to evaluate cardiac function using echocardiography and studied the pathological changes following COP. Results: The 20 942 patients in the COP cohort had a higher risk for CHF than the 62 826 members in the non-COP cohort after adjusting for sex and underlying comorbidities (adjusted hazard ratio, 2.01 [95% CI, 1.74–2.32]). The increased risk of CHF persisted even after 2 years of follow-up (adjusted hazard ratio, 1.85 [95% CI, 1.55–2.21]). In the animal model, COP led to a decreased left ventricular ejection fraction on echocardiography and damage to cardiac cells with remarkable fibrotic changes. Conclusions: Our epidemiological data showed an increased risk of CHF was associated with COP, which was supported by the animal study. We suggest close follow-up of cardiac function for patients with COP to facilitate early intervention and further studies to identify other long-term effects that have not been reported in the literature.

Introduction:Pergolide is an ergot derived dopamine agonist that is widely used for the treatment of Parkinson’s disease. Studies have found an association between pergolide and valvular heart abnormalities although there is still much to be learned about the clinical significance of the valvular changes, who is at risk, and whether there is duration of exposure effect.Objective:To assess the long term risk of hospital admissions for valvular heart disease (VHD) or congestive heart failure (CHF, a clinically overt outcome of VHD) in new users of pergolide compared to new users of levodopa. The secondary objective was to assess whether there are any characteristics that can predict who is at higher risk of developing this outcome.Design:Retrospective, population-based cohort study.Setting:Ontario, Canada.Subjects:Ontario residents aged 66 and older, newly started on treatment with either pergolide or levodopa.Outcomes:Admission to hospital with the most responsible diagnosis of congestive heart failure or valvular heart disease.Results:The risk for admission for valvular heart disease or congestive heart failure were higher in those with 1-4 years exposure to pergolide compared with no exposure to pergolide (VHD: hazard ratio 2.4, p = 0.04; CHF: hazard ratio 1.6, p =0.02). No such pattern was found with exposure to levodopa.Conclusion:Our study demonstrates that treatment with pergolide is associated with a higher risk of hospital admission for valvular heart disease or congestive heart failure and that this risk is greater in those with 1-4 years exposure than in those with less exposure. We did not find an increased risk beyond four years.

Repetitive or recurrent hospitalizations are a general major health issue in patients with chronic disease. Congestive heart failure, is associated with a high incidence and presence of early rehospitalization, but variables in order to identify patients at increased risk and also an analysis of potentially remediable factors contributing to readmission have not been previously reported and it remains still a difficult problem. We retrospectively assessed 100 patients aged between 48-85 years old, of which 75% were men, who had been hospitalized with documentation of congestive heart failure in St. Spiridon County Emergency Hospital. They were hospitalized between 2010-2017. Even if recurrent heart failure was the most common cause for readmission or rehospitalization, other cardiac disorders and noncardiac illnesses were also accounted for readmission. Predictive factors of an increased probability of readmission included prior patient�s medical heart failure history, heart failure decompensation precipitated or accelerated by an ischaemic episode, atrial fibrillation or uncontrolled hypertension. Factors contributing to preventable readmissions included noncompliance with medications or diet, inadequate discharge planning or follow-up, failure of both social support system and the seek of a promp medical attention when symptoms reappeared. We also identified an inappropriate colaboration with family doctors especially for the patients from rural areas. Patients were more likely to cite side effects of prescribed medications rather than nonadherence as a precipitating factor for readmission. Thus, we can appreciate that early rehospitalization in patients with congestive heart failure may be avoidable in up to 50% of cases. Identification of high risk patients is possible and also necessary shortly after admission in order to identify nonpharmacological interventions designed to decrease readmission frequency.

Purpose: Septic shock (SS) manifests with profound circulatory and cellular metabolism abnormalities and has a high in-hospital mortality (25%-50%). Congestive heart failure (CHF) patients have underlying circulatory dysfunction and compromised cardiac reserve that may place them at increased risk if they develop sepsis. Outcomes in patients with CHF who are admitted with SS have not been well studied. Materials and Method: Retrospective cross sectional secondary analysis of the Nationwide Readmission Database (NRD) for 2016 and 2017. ICD-10 codes were used to identify patients with SS during hospitalization, and then the cohort was dichotomized into those with and without an underlying diagnosis of CHF. Results: Propensity match analyses were performed to evaluate in-hospital mortality and clinical cardiovascular outcomes in the 2 groups. Cardiogenic shock patients were excluded from the study. A total of 578,629 patients with hospitalization for SS were identified, of whom 19.1% had a coexisting diagnosis of CHF. After propensity matching, 81,699 individuals were included in the comparative groups of SS with CHF and SS with no CHF. In-hospital mortality (35.28% vs 32.50%, P < .001), incidence of ischemic stroke (2.71% vs 2.53%, P = .0032), and acute kidney injury (69.9% vs 63.9%, P = .001) were significantly higher in patients with SS and CHF when compared to those with SS and no CHF. Conclusions: This study identified CHF as a strong adverse prognosticator for inpatient mortality and several major adverse clinical outcomes. Study findings suggest the need for further investigation into these findings’ mechanisms to improve outcomes in patients with SS and underlying CHF.

Introduction: Proton pump inhibitors (PPIs) are used by an estimated 29 million Americans. PPIs increase the levels of asymmetrical dimethylarginine, a known risk factor for cardiovascular disease (CVD). Data from a select population of patients with CVD suggest that PPI use is associated with an increased risk of stroke, heart failure, and coronary heart disease. The impact of PPI use on incident CVD is largely unknown in the general population. Hypothesis: We hypothesized that PPI users have a higher risk of incident total CVD, coronary heart disease, stroke, and heart failure compared to nonusers. To demonstrate specificity of association, we additionally hypothesized that there is not an association between use of H 2 -blockers - another commonly used class of medications with similar indications as PPIs - and CVD. Methods: We used the Rochester Epidemiology Project’s medical records-linkage system to identify all residents of Olmsted County, MN on our baseline date of January 1, 2004 (N=140217). We excluded persons who did not grant permission for their records to be used for research, were <18 years old, had a history of CVD, had missing data for any variable included in our model, or had evidence of PPI use within the previous year.We followed our final cohort (N=58175) for up to 12 years. The administrative censoring date for CVD was 1/20/2014, for coronary heart disease was 8/3/2016, for stroke was 9/9/2016, and for heart failure was 1/20/2014. Time-varying PPI ever-use was ascertained using 1) natural language processing to capture unstructured text from the electronic health record, and 2) outpatient prescriptions. An incident CVD event was defined as the first occurrence of 1) validated heart failure, 2) validated coronary heart disease, or 3) stroke, defined using diagnostic codes only. As a secondary analysis, we calculated the association between time-varying H 2 -blocker ever-use and CVD among persons not using H 2 -blockers at baseline. Results: After adjustment for age, sex, race, education, hypertension, hyperlipidemia, diabetes, and body-mass-index, PPI use was associated with an approximately 50% higher risk of CVD (hazard ratio [95% CI]: 1.51 [1.37-1.67]; 2187 CVD events), stroke (hazard ratio [95% CI]: 1.49 [1.35-1.65]; 1928 stroke events), and heart failure (hazard ratio [95% CI]: 1.56 [1.23-1.97]; 353 heart failure events) compared to nonusers. Users of PPIs had a 35% greater risk of coronary heart disease than nonusers (95% CI: 1.13-1.61; 626 coronary heart disease events). Use of H 2 -blockers was also associated with a higher risk of CVD (adjusted hazard ratio [95% CI]: 1.23 [1.08-1.41]; 2331 CVD events). Conclusions: PPI use is associated with a higher risk of CVD, coronary heart disease, stroke and heart failure. Use of a drug with no known cardiac toxicity - H 2 -blockers - was also associated with a greater risk of CVD, warranting further study.

Abstract Background: Triglyceride-glucose (TyG) index and homeostasis model assessment-insulin resistance (HOMA-IR) are related to insulin resistance (IR). The aim of this study was to assess the association between triglyceride-glucose index / HOMA-IR within young adults and congestive heart failure (CHF), and to explore whether triglyceride-glucose index can replace HOMA-IR as a surrogate marker for insulin resistance in predicting the risk of CHF.Methods:A total of 4992 participants between the ages of 18 and 30 were enrolled from the Coronary Artery Risk Development in Young Adults (CARDIA) investigation (from 1985 to 1986 [year 0]). Cox proportional hazard regression analysis was conducted for assessing correlations between baseline TyG index / HOMA-IR and congestive heart failure events, together with Receiver Operating Characteristic (ROC) Curve employed for scrutinizing TyG index / HOMA-IR and he risk of CHF.Results: During the 31-year follow-up period, 64 (1.3%) out of the 4992 participants developed congestive heart failure. In multivariable Cox proportional hazards models, adjusted for confounding factors for CHF, increased risk of CHF was associated with per-unit increase in TyG index (hazard ratio [HR] 2.8; 95% confidence interval [CI], 1.7-4.7) and HOMA-IR (HR 1.2; 95%CI, 1.1-1.3). Kaplan-Meier curve analysis showed that participants in the TyG index and HOMA-IR index Q4 group had a higher risk of congestive heart failure than those in the Q1 group. The area under curve (AUC) for TyG index and HOMA-IR consisted of 0.67 (95% CI, 0.6-0.742) and 0.675 (95%CI, 0.604-0.746), respectively. There were no significant differences between TyG index and HOMA-IR for AUC (P = 0.986).Conclusions: TyG index and HOMA-IR are independent risk factors for CHF. The TyG index can replace HOMA-IR in young adulthood as a surrogate marker for IR to predict the risk of CHF.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction The HeartLogic algorithm combines multiple implantable cardioverter defibrillator (ICD) sensors to identify patients at risk of heart failure (HF) events. Purpose We sought to evaluate the risk stratification ability of this algorithm in clinical practice. We also analyzed the alert management strategies adopted in the study group and their association with the occurrence of HF events. Methods The HeartLogic feature was activated in 366 ICD and cardiac resynchronization therapy ICD patients at 22 centers. The HeartLogic algorithm automatically calculates a daily HF index and identifies periods IN or OUT of an alert state on the basis of a configurable threshold (in this analysis set to 16). Results The HeartLogic index crossed the threshold value 273 times (0.76 alerts/patient-year) in 150 patients over a median follow-up of 11 months [25-75 percentile: 6-16]. Overall, the time IN the alert state was 11% of the total observation period. Patients experienced 36 HF hospitalizations and 8 patients died of HF (rate: 0.12 events/patient-year) during the observation period. Thirty-five events were associated with the IN alert state (0.92 events/patient-year versus 0.03 events/patient-year in the OUT of alert state). The hazard ratio in the IN/OUT of alert state comparison was (HR: 24.53, 95% CI: 8.55-70.38, p &lt; 0.001), after adjustment for baseline clinical confounders. Alerts followed by clinical actions were associated with a lower rate of HF events (HR: 0.37, 95% CI: 0.14-0.99, p = 0.047). No differences in event rates were observed between in-office and remote alert management. By contrast, verification of HF symptoms during post-alert examination was associated with a higher risk of HF events (HR: 5.23, 95% CI: 1.98-13.83, p &lt; 0.001). Conclusions This multiparametric ICD algorithm identifies patients during periods of significantly increased risk of HF events. The rate of HF events seemed lower when clinical actions were undertaken in response to alerts. Extra in-office visits did not seem to be required in order to effectively manage HeartLogic alerts, while post-alert verification of symptoms seemed useful in order to better stratify patients at risk of HF events.
