People with HIV (PWH) and people with diabetes mellitus have increased risk of severe COVID-19, but little is known about humoral response to COVID-19 vaccines in PWH with DM. We investigated SARS-CoV-2 antireceptor-binding domain (anti-RBD) immunoglobulin G (IgG) geometrical concentrations and neutralizing antibody capacity (nAB) in PWH with and without diabetes mellitus. Anti-RBD IgG and nAB in COVID-19-vaccinated PWH were not associated with diabetes mellitus-status or HbA1c 24 months after the initial COVID-19 vaccination.

Transurethral resection of the prostate (TUR-P) may give rise to bacteremia, but the associated risk of IE is not well described. We aimed to examine risk of infective endocarditis following TUR-P.

We investigated the risk of SARS-CoV-2 infection and severe COVID-19 among healthcare workers according to prescription drug use. We conducted an observational study among Danish healthcare workers.

In cases of TAVI endocarditis, the treatment possibilities may be limited as surgical removal of the infected valve may be associated with a high risk in elderly, comorbid or frail patients. The propensity of bacteria to form a biofilm on foreign material is assumed to be of importance part of the disease process in TAVI endocarditis, but no studies on biofilm formation on TAVI valves have been conducted.

First-degree relatives to younger SCD patients should be evaluated for inherited cardiovascular disease, as argued in this review. An improved understanding of SCD subtypes and genetics is expected to improve risk stratification and SCD prevention.
View Article and Find Full Text PDFThis review outlines the workflow for patients and relatives with suspected inherited cardiovascular disease, diagnostic criteria, inheritance patterns, and »red flags« for selected conditions. Evaluation for inherited cardiovascular disease typically includes the index patient (proband) and relatives, emphasizing the importance of assessment at specialized clinics. Most inherited cardiovascular conditions have an autosomal dominant inheritance, but other patterns are seen.

Patients And Methods: We randomly sampled 200 patients registered in DNPR with the diagnostic codes DI421 (obstructive) or DI422 (non-obstructive) HCM, from Eastern Denmark, between December 1, 2017, and September 16, 2021. We assessed patients' medical records and classified whether the diagnosis of HCM was correct, incorrect, or uncertain according to the European Society of Cardiology (ESC) guidelines.
Background: Hypertrophic cardiomyopathy (HCM) is a common inherited cardiac disease, and clinical and genetic family screening is recommended by guidelines.
Objectives: This study sought to investigate the diagnostic yield of screening relatives of HCM patients and identify predictive factors for HCM development during long-term follow-up in relatives from gene-elusive families.
Methods: This was a retrospective cohort study of families screened at clinics for inherited cardiomyopathies in Eastern Denmark, from 2006 to 2023.
Background: Cardiac troponin (cTn) is key in diagnosing myocardial infarction (MI). After MI, the clinically observed half-life of cTn has been reported to be 7 to 20 hours, but this estimate reflects the combined elimination and simultaneous release of cTn from cardiomyocytes. More precise timing of myocardial injuries necessitates separation of these 2 components.

Background: The aim of this study was to investigate the clinical implication of incidentally induced atrial fibrillation (AF) during programmed electrical stimulation (PES) in patients with left ventricular systolic dysfunction (≤40%) after an acute myocardial infarction (MI).
Methods: In this study, we included 231 patients from the Cardiac Arrhythmias and RIsk Stratification after Myocardial InfArction (CARISMA) study with left ventricular ejection fraction ≤40% and no prior history of AF. These patients underwent PES 6 weeks post-MI as part of the study protocol.
Background: Sex- and population-specific 99th percentiles of high-sensitivity cardiac troponin (hs-cTn) are recommended in guidelines although the evidence for a clinical utility is sparse. The DANSPOT trial will investigate the clinical effect of sex- and population-specific 99th percentiles of cTn. We report the 99th percentiles derived from this trial and their dependency on kidney function.
View Article and Find Full Text PDFBackground: The influence of age on cardiac troponin is unclear and may vary between cardiac troponin T (cTnT) and I (cTnI). We aimed to compare the impact of age on the diagnostic and prognostic utility of cTnT and cTnI.
Methods: This Danish nationwide, register-based cohort study included patients with at least one cardiac troponin (cTn) measurement from 2009 through June 2022, stratified into decades of age.
Background: The health-related quality of life (HRQOL) and cardiopulmonary exercise testing (CPET) performance of individuals with subclinical and early stage hypertrophic cardiomyopathy (HCM) have not been systematically studied. Improved understanding will inform the natural history of HCM and factors influencing well-being.
Methods: VANISH trial (Valsartan for Attenuating Disease Evolution in Early Sarcomeric HCM) participants with early stage sarcomeric HCM (primary analysis cohort) and subclinical HCM (sarcomere variant without left ventricular hypertrophy comprising the exploratory cohort) who completed baseline and year 2 HRQOL assessment via the pediatric quality of life inventory and CPET were studied.
encodes for the Popeye domain-containing protein 2 which has an important role in cardiac pacemaking and conduction, due in part to its cAMP-dependent binding and regulation of TREK-1 potassium channels. Loss of in mice results in sinus pauses and bradycardia and morpholino knockdown of zebrafish results in atrioventricular (AV) block. We identified bi-allelic variants in in 4 families that presented with a phenotypic spectrum consisting of sinus node dysfunction, AV conduction defects and hypertrophic cardiomyopathy.

Objectives: The authors aimed to examine changes in LV function and morphology in 2 to 4-year-old children with and without LVNC at birth and to describe the prevalence of LVNC in first-degree relatives.
Methods: Echocardiograms in children with and without LVNC (matched 1:4) were performed at 2 to 4 years and in first-degree relatives.
