Guideline-Directed Medical Therapy After Hospitalization for Acute Heart Failure: Insights From the CONNECT-HF.

Background: Significant gap remains in the implementation of guideline-directed medical therapy (GDMT) in patients with heart failure after a hospitalization. We aimed to evaluate the use and titration of GDMT at discharge and over a 12-month period after hospital discharge and to identify factors associated with GDMT use and titration.

Methods And Results: The CONNECT-HF (Care Optimization Through Patient and Hospital Engagement Clinical Trial for Heart Failure) trial evaluated the effect of a hospital and postdischarge quality improvement intervention in participants with heart failure with reduced ejection fraction.

Burden of Hyperlipidemia, Cardiovascular Mortality, and COVID-19: A Retrospective-Cohort Analysis of US Data.

Background: Hyperlipidemia is a major cardiovascular disease (CVD) risk factor, but limited data on its mortality trends in CVD over time. We assessed annual hyperlipidemia-related CVD mortality trends in the United States, including the COVID-19 pandemic's impact.

Methods And Results: Mortality data were obtained from CDC repository between 1999 and 2020 among patients ≥15 years old, using ICD-10 codes hyperlipidemia (E78.

Trends in Complications Among Patients Undergoing Aortic Valve Replacement in the United States.

Background: The treatment of severe aortic stenosis has evolved considerably since the introduction of transcatheter aortic valve replacement (TAVR), yet trends in complications for patients undergoing TAVR or surgical aortic valve replacement (SAVR) at a national level have yet to be evaluated.

Methods And Results: We performed a retrospective cohort study using Medicare data to evaluate temporal trends in complications among beneficiaries, aged ≥65 years, treated with elective isolated transfemoral TAVR or SAVR between 2012 and 2019. The study end point was the occurrence of a major complication (composite outcome) during index and up to 30 days after.

Trends and Disparities in Valvular Heart Disease Mortality in the United States From 1999 to 2020.

Background: Percutaneous heart valve procedures have been increasingly performed over the past decade, yet real-world mortality data on valvular heart disease (VHD) in the United States remain limited.

Methods And Results: We queried the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database among patients ≥15 years old from 1999 to 2020. VHD and its subtypes were listed as the underlying cause of death.

Trends and Disparities in Cardiovascular Death in Sarcoidosis: A Population-Based Retrospective Study in the United States From 1999 to 2020.

Background: Despite significant cardiac involvement in sarcoidosis, real-world data on death due to cardiovascular disease among patients with sarcoidosis is not well established.

Methods And Results: We queried the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database for data on patients with sarcoidosis aged ≥25 years from 1999 to 2020. Diseases of the circulatory system except ischemic heart disease were listed as the underlying cause of death, and sarcoidosis was stated as a contributing cause of death.

Risk Prediction in Male Adolescents With Congenital Long QT Syndrome: Implications for Sex-Specific Risk Stratification in Potassium Channel-Mediated Long QT Syndrome.

Background: Sex-specific risk management may improve outcomes in congenital long QT syndrome (LQTS). We recently developed a prediction score for cardiac events (CEs) and life-threatening events (LTEs) in postadolescent women with LQTS. In the present study, we aimed to develop personalized risk estimates for the burden of CEs and LTEs in male adolescents with potassium channel-mediated LQTS.

Factors Associated With Maintenance of an Improved Ejection Fraction: An Echocardiogram-Based Registry Study.

Background Heart failure with improved ejection fraction (EF) is increasingly recognized as a sizable and distinct entity. While the features associated with improvedEF have been explored and new guidelines have emerged, factors associated with sustaining an improved EF over time have not been defined. We aimed to assess factors associated with maintenance of an improved EF in a large real-world patient cohort.

Health-Related Quality of Life in Older Patients With Advanced Heart Failure: Findings From the SUSTAIN-IT Study.

Background There is a paucity of research describing health-related quality of life (HRQOL) in older adults considered for advanced heart failure surgical therapies. Using data from our SUSTAIN-IT (Sustaining Quality of Life of the Aged: Heart Transplant or Mechanical Support) study, we aimed to compare HRQOL among 3 groups of older (60-80 years) patients with heart failure before heart transplantation (HT) or long-term mechanical circulatory support (MCS) and identify factors associated with HRQOL: (1) HT candidates with MCS, (2) HT candidates without MCS, or (3) candidates ineligible for HT and scheduled for long-term MCS. Methods and Results Patients from 13 US sites completed assessments, including self-reported measures of HRQOL (EuroQol-5 Dimension Questionnaire, Kansas City Cardiomyopathy Questionnaire-12), depressive symptoms (Personal Health Questionnaire-8), anxiety (State-Trait Anxiety Inventory-state form), cognitive status (Montreal Cognitive Assessment), and performance-based measures (6-minute walk test and 5-m gait speed).

Sex Differences in the Age of Diagnosis for Cardiovascular Disease and Its Risk Factors Among US Adults: Trends From 2008 to 2017, the Medical Expenditure Panel Survey.

Background Sex differences in the trends for control of cardiovascular disease (CVD) risk factors have been described, but temporal trends in the age at which CVD and its risk factors are diagnosed and sex-specific differences in these trends are unknown. Methods and Results We used the Medical Expenditure Panel Survey 2008 to 2017, a nationally representative sample of the US population. Individuals ≥18 years, with a diagnosis of hypercholesterolemia, hypertension, coronary heart disease, or stroke, and who reported the age when these conditions were diagnosed, were included.

Renin-Angiotensin System Blockade in Aortic Stenosis: Implications Before and After Aortic Valve Replacement.

Aortic stenosis (AS) is a common valvular heart disease in the aging population that is characterized by a variable period of asymptomatic phase before development of symptoms and severe AS. Mortality and morbidity is substantial even after aortic valve replacement, in part related to persistent left ventricular hypertrophy, diastolic dysfunction, and heart failure. Renin-angiotensin system (RAS) blockade therapy is associated with modulation of adverse left ventricular remodeling, reduction in myocardial hypertrophy, and fibrosis, resulting in clinical improvements in patients with congestive heart failure There are emerging data to suggest benefit of RAS blockade in patients with AS before and after AVR with regard to potentially slower progression of aortic valve calcification, left ventricular mass and survival benefit in favor of RAS blockade group before AVR, and also survival benefit in patients after AVR.

Dynamic Forecasts of Survival for Patients Living With Destination Left Ventricular Assist Devices: Insights From INTERMACS.

Background Left ventricular assist devices (LVADs) improve outcomes in patients with end-stage heart failure and are increasingly implanted for destination therapy. We describe dynamic estimates of event-free survival with conditional survival probabilities in a destination therapy LVAD population. Methods and Results We studied 8245 adult patients in INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) implanted with a continuous-flow destination therapy LVAD.

Atrial Tissue Pro-Fibrotic M2 Macrophage Marker CD163+, Gene Expression of Procollagen and B-Type Natriuretic Peptide.

Background Atrial tissue fibrosis is linked to inflammatory cells, yet is incompletely understood. A growing body of literature associates peripheral blood levels of the antifibrotic hormone BNP (B-type natriuretic peptide) with atrial fibrillation (AF). We investigated the relationship between pro-fibrotic tissue M2 macrophage marker Cluster of Differentiation (CD)163+, atrial procollagen expression, and BNP gene expression in patients with and without AF.

Genetic Determinants of Circulating Glycine Levels and Risk of Coronary Artery Disease.

Background Recent studies have revealed sexually dimorphic associations between the carbamoyl-phosphate synthase 1 locus, intermediates of the metabolic pathway leading from choline to urea, and risk of coronary artery disease ( CAD ) in women. Based on evidence from the literature, the atheroprotective association with carbamoyl-phosphate synthase 1 could be mediated by the strong genetic effect of this locus on increased circulating glycine levels. Methods and Results We sought to identify additional genetic determinants of circulating glycine levels by carrying out a meta-analysis of genome-wide association study data in up to 30 118 subjects of European ancestry.
