Background: The electrocardiographic PR interval increases with aging, differs by race, and is associated with atrial fibrillation (AF), pacemaker implantation, and all-cause mortality. We sought to determine the associations between PR interval and heart failure, AF, and mortality in a biracial cohort of older adults.
Methods And Results: The Health, Aging, and Body Composition (Health ABC) Study is a prospective, biracial cohort. We used multivariable Cox proportional hazards models to examine PR interval (hazard ratios expressed per SD increase) and 10-year risks of heart failure, AF, and all-cause mortality. Multivariable models included demographic, anthropometric, and clinical variables in addition to established cardiovascular risk factors. We examined 2722 Health ABC participants (aged 74±3 years, 51.9% women, and 41% black). We did not identify significant effect modification by race for the outcomes studied. After multivariable adjustment, every SD increase (29 ms) in PR interval was associated with a 13% greater 10-year risk of heart failure (95% confidence interval, 1.02-1.25) and a 13% increased risk of incident AF (95% confidence interval, 1.04-1.23). PR interval >200 ms was associated with a 46% increased risk of incident heart failure (95% confidence interval, 1.11-1.93). PR interval was not associated with increased all-cause mortality.
Conclusions: We identified significant relationships of PR interval to heart failure and AF in older adults. Our findings extend prior investigations by examining PR interval and associations with adverse outcomes in a biracial cohort of older men and women.

Background: We still know little about the effective pharmacological treatment of heart failure (HF) associated with the Fontan circulation. One of the new options may be sodium glucose cotransporter-2 inhibitors (SGLT2i), which have been proven effective in classic forms of left ventricular HF.
Objectives: To evaluate the effect and safety of SGLT2i inclusion in adults with Fontan circulation.

Objective: To describe the characteristics of patients diagnosed with acute heart failure (AHF) in emergency departments (EDs) who develop cardiogenic shock (CS) not associated with ST-segment elevation acute coronary syndrome (STACS).
Methods: Information for patients diagnosed with AHF in 23 Spanish EDs and registered between 2009 and 2019 were included for analysis if the patients developed symptoms consistent with CS. We described baseline clinical characteristics related to cardiac decompensation and CS, as well as 30-day mortality.

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia around the world with an increased risk of a broad spectrum of adverse comorbidities and death. Whether cardiovascular health (CVH) is associated with AF development remains unclear.
Methods: 238,420 participants without cardiovascular disease at baseline were selected from the UK Biobank study cohort from 2006 to 2010.

Background And Aims: Atherosclerotic cardiovascular disease (ASCVD) is a leading cause of mortality, and while the association between the urinary albumin-to-creatinine ratio (UACR) and cardiovascular risk is recognized, the specific impact of UACR on the long-term survival of ASCVD patients remains not fully understood. The aim of this study is to investigate the influence of UACR on the long-term risk of all-cause mortality in patients with ASCVD.
Methods: This study included ASCVD patients from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018.

Background: Heart failure (HF) is a significant cause of death among patients with chronic kidney disease (CKD). Emerging data suggest a crucial role of fibroblast growth factor 23 (FGF23) in the pathogenesis of HF in CKD patients. The present study aimed to investigate whether the serum intact FGF23 (iFGF23) level is elevated when ejection fraction (EF) is preserved and to evaluate its predictive value for incident HF and cardiac mortality in CKD patients with preserved EF.
