Computed tomography or chest X-ray to assess pulmonary congestion in dyspnoeic patients with acute heart failure.

Aims: While computed tomography (CT) is widely acknowledged as superior to chest radiographs for acute diagnostics, its efficacy in diagnosing acute heart failure (AHF) remains unexplored. This prospective study included consecutive patients with dyspnoea undergoing simultaneous low-dose chest CT (LDCT) and chest radiographs. Here, we aimed to determine if LDCT is superior to chest radiographs to confirm pulmonary congestion in dyspnoeic patients with suspected AHF.

Remote dielectric sensing to detect acute heart failure in patients with dyspnoea: a prospective observational study in the emergency department.

Aims: Remote dielectric sensing (ReDS) enables quick estimation of lung fluid content. To examine if ReDS is superior to other methods in detecting acute heart failure.

Methods And Results: We included consecutive patients with dyspnoea from the emergency departments at Bispebjerg Hospital, Copenhagen, and performed ReDS, low-dose chest computed tomography (CT), echocardiogram, lung ultrasound, NT-Pro-brain natriuretic peptide (NT-proBNP), and a Boston score evaluation (chest X-ray and clinical signs).

Chest computed tomography features of heart failure: A prospective observational study in patients with acute dyspnea.

Background: Pulmonary congestion is a key component of heart failure (HF) that chest computed tomography (CT) can detect. However, no guideline describes which of many anticipated CT signs are most associated with HF in patients with undifferentiated dyspnea.

Methods: In a prospective observational single-center study, we included consecutive patients ≥ 50 years admitted with acute dyspnea to the emergency department.

P-wave indices as predictors of atrial fibrillation.

Background: P-wave duration (P ) and P-wave area (P ) have been linked to risk of atrial fibrillation (AF), but they do not improve the efficacy of Framingham AF risk score. We suggest the incorporation of both variables in one index, the P-wave area/P-wave duration (P ) index, which may be considered an expression of the average amplitude of the P wave that reflects aspects of P-wave morphology.

Objective: To assess the prognostic value of P-wave area/P-wave duration index (P index) in lead II together with other P-wave indices (PWIs) in incidence of AF in the Copenhagen Holter Study.

Clinical Applicability of Lung Ultrasound Methods in the Emergency Department to Detect Pulmonary Congestion on Computed Tomography.

Background:  B-lines on lung ultrasound are seen in decompensated heart failure, but their diagnostic value in consecutive patients in the acute setting is not clear. Chest CT is the superior method to evaluate interstitial lung disease, but no studies have compared lung ultrasound directly to congestion on chest CT.

Purpose:  To examine whether congestion on lung ultrasound equals congestion on a low-dose chest CT as the gold standard.

Echocardiographic subtypes of heart failure in consecutive hospitalised patients with dyspnoea.

Unlabelled: Heart failure with preserved ejection fraction (HFpEF) involves half of hospitalised patients with heart failure (HF), but estimates vary due to unclear diagnostic criteria. We performed a prospective observational study of hospitalised patients admitted with dyspnoea. The aim was to apply contemporary guidelines to diagnose HF due to valvular disease (HFvhd), HF due to reduced ejection fraction (HFrEF), HF due to midrange EF (HFmrEF) and HFpEF in relation to presumed cardiac or non-cardiac dyspnoea.

Common source of miscalculation and misclassification of P-wave negativity and P-wave terminal force in lead V1.

Background: P-wave terminal force (PTF) > 4000 ms·μV and deep terminal negativity (DTN) are ECG markers of left atrial abnormality associated with both atrial fibrillation and stroke. When the precordial lead V1 is placed higher than the correct position in the fourth intercostal space, it may cause increased PTF and DTN. Several studies have documented that electrode misplacement, especially high placement, is common.

Rationale and Design of the First Double-Blind, Placebo-Controlled Trial with Allogeneic Adipose Tissue-Derived Stromal Cell Therapy in Patients with Ischemic Heart Failure: A Phase II Danish Multicentre Study.

Background: Ischemic heart failure (IHF) has a poor prognosis in spite of optimal therapy. We have established a new allogeneic Cardiology Stem Cell Centre adipose-derived stromal cell (CSCC_ASC) product from healthy donors. It is produced without animal products, in closed bioreactor systems and cryopreserved as an off-the-shelf product ready to use.

Effects of the glucagon-like peptide-1 receptor agonist liraglutide on 24-h ambulatory blood pressure in patients with type 2 diabetes and stable coronary artery disease: a randomized, double-blind, placebo-controlled, crossover study.

Objective: The glucagon-like peptide-1 receptor agonist liraglutide has been shown to reduce blood pressure (BP) in clinical trials using office BP measurements. However, the effects of liraglutide on 24-h BP and on the diurnal variation in BP have not been explored sufficiently.

Methods: Forty-one patients with type 2 diabetes and stable coronary artery disease were randomized to receive liraglutide or placebo to a backbone therapy of metformin in this double-blind, placebo-controlled 12 along with 12 weeks crossover study.

Point-of-care procalcitonin test to reduce antibiotic exposure in patients hospitalized with acute exacerbation of COPD.

Background: This study was conducted to investigate whether point-of-care (POC) procalcitonin (PCT) measurement can reduce redundant antibiotic treatment in patients hospitalized with acute exacerbation of COPD (AECOPD).

Methods: One-hundred and twenty adult patients admitted with AECOPD were enrolled in this open-label randomized trial. Patients were allocated to either the POC PCT-guided intervention arm (n=62) or the control arm, in which antibiotic therapy followed local guidelines (n=58).

Reduced cerebral oxygen-carbohydrate index during endotracheal intubation in vascular surgical patients.

Brain activation reduces balance between cerebral consumption of oxygen versus carbohydrate as expressed by the so-called cerebral oxygen-carbohydrate-index (OCI). We evaluated whether preparation for surgery, anaesthesia including tracheal intubation and surgery affect OCI. In patients undergoing aortic surgery, arterial to internal jugular venous (a-v) concentration differences for oxygen versus lactate and glucose were determined from before anaesthesia to when the patient left the recovery room.
