Abstract Objective To examine the effect of optimising drug treatment on related hospital admissions in older adults with multimorbidity and polypharmacy admitted to hospital. Design Cluster randomised controlled trial. Setting 110 clusters inpatient wards within university based hospitals four European countries (Switzerland, Netherlands, Belgium, Republic Ireland) defined by attending doctors. Participants 2008 (≥70 years) (≥3 chronic conditions) (≥5 drugs used long term). Intervention...

Endogenous estrogens protect from coronary artery disease in premenopausal women, but the mechanisms involved are only partly understood. This study investigated whether activation of novel G protein-coupled estrogen receptor (GPER, formerly known as GPR30) affects tone, and this is affected by concomitant blockade receptors (ER) alpha beta. Rings epicardial porcine arteries suspended organ chambers were precontracted with prostaglandin F(2)alpha, direct effects G-1 (GPER agonist) ICI...

Abstract Background Diabetes overtreatment is a frequent and severe issue in multimorbid older patients with type 2 diabetes (T2D). Objective This study aimed at assessing the association between 1-year functional decline, hospitalisation mortality inpatients multimorbidity polypharmacy. Methods Ancillary of European multicentre OPERAM project on aged ≥70 years T2D glucose-lowering treatment (GLT). was defined according to 2019 Endocrine Society guideline using HbA1c target range...

Background Diabetes is a major risk factor for atrial fibrillation (AF). However, it remains unclear whether individual AF phenotype and related comorbidities differ between patients who have with without diabetes. This study investigated the association of diabetes cardiac neurological in documented AF. Methods Results Participants multicenter Swiss‐AF (Swiss Atrial Fibrillation) data on were eligible.

Abstract Background In multimorbid older patients with type 2 diabetes mellitus (T2DM), the intensity of glucose‐lowering medication (GLM) should be focused on attaining a suitable level glycated hemoglobin (HbA 1c ) while avoiding side effects. We aimed at identifying overtreatment T2DM as well associated risk factors. Methods secondary analysis multicenter study patients, we evaluated HbA levels among T2DM. Patients were aged ≥70 years, multimorbidity (≥3 chronic diagnoses) and...

The omega-3 fatty acid (n-3 FA) eicosapentaenoic (EPA) reduces stroke in patients with atherosclerotic cardiovascular disease. Whether EPA affects or cerebral small vessel dis-ease atrial fibrillation (AF) remains uncertain. EPA, docosahexaenoic (DHA), docosapentaenoic (DPA), and alpha-linolenic (ALA) were determined by gas chromatography 1657 AF from the Swiss Atrial Fibrillation study. All underwent brain MRI to detect ischemic infarcts, classified as large noncortical cortical infarcts...

<h3>BACKGROUND:</h3> Little is known about the association between alcohol consumption and risk of cardiovascular events in patients with established atrial fibrillation (AF). The main aim current study was to investigate associations regular intake incident stroke or systemic embolism AF. <h3>METHODS:</h3> To assess AF, we combined data from 2 comparable prospective cohort studies that followed 3852 AF for a median 3.0 years. Patients were grouped into 4 categories daily (none, &gt; 0 &lt;...

Abstract Background Patients with atrial fibrillation (AF) have a high risk of hospital admissions, but there is no validated prediction tool to identify those at highest risk. Purpose To develop and externally validate score for all-cause admissions in patients AF. Methods We used prospective cohort 2387 established AF as derivation cohort. Independent factors were selected from broad range variables using the least absolute shrinkage selection operator (LASSO) method fit Cox regression...

The beneficial effect of statins on the risk recurrence cardiovascular disease (secondary prevention) is well demonstrated. In primary prevention (no symptomatic disease), benefit after age 70 years less clear and elderly patients with comorbidities have often been excluded from large, randomized trials. Some ongoing clinical trials will provide more information potential benefits risks starting or stopping in older adults. practice, decision to treat needs take into account age,...

Endothelium-dependent contractions are augmented in human hypertension and isolated preparations, including renal arteries, from hypertensive animals. Renal vasomotor tone is essential the regulation of arterial blood pressure arteries highly sensitive to vasoconstrictor prostanoids prostacyclin, identified as endothelium-derived contracting factor (EDCF) activating thromboxane prostanoid (TP) receptors.
