Article Synopsis
- This study looked at people in Sweden who had kidney disease but didn't know it, to see how often they got diagnosed and treated.
- Out of nearly 100,000 people with undiagnosed kidney disease, only about 1 in 3 were diagnosed in five years, and not many were treated with the right medications.
- If all of them had received proper treatment, many deaths and heart problems could have been avoided, showing there's a big opportunity to help these patients better.
Aims: This study aimed to characterize a contemporary population with subtypes of incident or prevalent heart failure (HF) based on reduced (HFrEF), mildly reduced, or preserved (HFpEF) left ventricular ejection fraction (LVEF) and to assess how outcomes, healthcare, treatments, and healthcare costs vary between each subtype of incident HF.
Methods And Results: Using Swedish data from the CardioRenal and Metabolic disease Heart Failure (CaReMe HF) study, updated to cover a more recent time period, this population-based study characterized patients from Stockholm County, Sweden, with incident HF (patients with a first HF diagnosis between 1 January 2015 and 31 December 2019) or prevalent HF (patients with a first HF diagnosis before 1 January 2020). Patients with incident HF had LVEF measured by echocardiography within ±90 days of their first HF diagnosis, and patients with prevalent HF within 5 years prior to the index date.
Aims: To compare prognosis between individuals without diabetes, type 1 and type 2 diabetes in a nationwide atrial fibrillation cohort in Sweden and study the significance of severe hypoglycaemia.
Methods: Using data from all-inclusive national registers, 309,611 patients with non-valvular atrial fibrillation were enrolled during 2013-2014. Of these, 2,221 had type 1 and 58,073 had type 2 diabetes.
Background: Disturbances of glucose metabolism can be diagnosed by an oral glucose tolerance test (OGTT) and by glycated haemoglobin (HbA1c). The aim of this study was to investigate the association between newly detected disturbances of glucose metabolism and long-term prognosis after acute myocardial infarction (AMI) and to compare the predictive value of an OGTT and HbA1c.
Methods: Patients under the age of 80 years with no known history of diabetes admitted for AMI at the Department of Cardiology, Danderyd University Hospital, Stockholm, Sweden, from January 1st, 2006 until December 31st, 2013, were investigated with an OGTT and a HbA1c before discharge and were classified as having normal glucose tolerance (NGT), prediabetes or diabetes according to American Diabetes Association (ADA) criteria.
Background: Disturbances of glucose metabolism are important risk factors for coronary artery disease and are associated with an increased mortality risk. The aim was to investigate the association between preoperative disturbances of glucose metabolism and long-term all-cause mortality after coronary artery bypass grafting (CABG).
Methods: Patients undergoing a first isolated CABG in 2005-2013 were included.
Aim: To describe nationwide complication patterns in patients with atrial fibrillation and diabetes mellitus.
Methods: All ( n = 326,832) patients in Sweden with non-valvular atrial fibrillation during 2006-2012 were identified, and information on events, comorbidities and pharmacological therapy was extracted using nationwide mandatory registers. Patients were followed until 31 December 2013 and the mean follow-up time was 3.
