Endoscopy: images from the inside of blood vessels

Researchers of the Universities of Stuttgart and Adelaide in cooperation with medical research centers in Australia developed a special microoptical tool with a thickness of only 125 microns. This enables endoscopic examimations within blood vessels whose diameter is smaller than 0.5 mm and helps detecting plaques or thrombs to reduce the danger of a strokeContinue reading “Endoscopy: images from the inside of blood vessels”

Heart scans could lead to better treatment for patients in hospital with coronavirus

13 July 2020     Julia Bakker    Half of Covid-19 patients who received a heart scan in hospital showed abnormalities in heart function, according to new research funded by us. The study, published in the European Heart Journal – Cardiovascular Imaging, found that around one in seven showed severe abnormalities likely to have a major effectContinue reading “Heart scans could lead to better treatment for patients in hospital with coronavirus”

Sex Differences in the Association of Cumulative Body Mass Index from Early Adulthood to Middle Age and Left Atrial Remodeling Evaluated by Three-Dimensional Echocardiography: The Coronary Artery Risk Development in Young Adults Study

Doria de Vasconcellos et al, J Am Soc Echocardiogr 2020;33:878-87. Background: The relationship between long-term obesity and left atrial (LA) structure and function is not entirely understood. We examined the association of cumulative body mass index (cBMI) with LA remodeling using three-dimensional (3D) speckle-tracking echocardiography (STE). Methods: The Coronary Artery Risk Development in Young AdultsContinue reading “Sex Differences in the Association of Cumulative Body Mass Index from Early Adulthood to Middle Age and Left Atrial Remodeling Evaluated by Three-Dimensional Echocardiography: The Coronary Artery Risk Development in Young Adults Study”

Heritable arrhythmias associated with abnormal function of cardiac potassium channels

Lia Crotti, Katja E Odening, Michael C Sanguinetti Cardiovascular Research, Volume 116, Issue 9, 15 July 2020, Pages 1542–1556 Abstract Cardiomyocytes express a surprisingly large number of potassium channel types. The primary physiological functions of the currents conducted by these channels are to maintain the resting membrane potential and mediate action potential repolarization under basalContinue reading “Heritable arrhythmias associated with abnormal function of cardiac potassium channels”

Diagnostic accuracy of handheld electrocardiogram devices in detecting atrial fibrillation in adults in community versus hospital settings: a systematic review and meta-analysis

Kam Cheong Wong1,2,3,4, Harry Klimis1,2,5, Nicole Lowres6, Amy von Huben1, Simone Marschner1, Clara K Chow1,2,5,6 Abstract With increasing use of handheld ECG devices for atrial fibrillation (AF) screening, it is important to understand their accuracy in community and hospital settings and how it differs among settings and other factors. A systematic review of eligible studiesContinue reading “Diagnostic accuracy of handheld electrocardiogram devices in detecting atrial fibrillation in adults in community versus hospital settings: a systematic review and meta-analysis”

Mildly symptomatic heart failure with reduced ejection fraction: diagnostic and therapeutic considerations

Alexandra Arvanitaki, Eleni Michou, Andreas Kalogeropoulos, Haralambos Karvounis, George Giannakoulas Abstract Aims Whereas up to about half of patients with heart failure with reduced ejection fraction (HFrEF) report no or only mild symptoms and are considered as clinically stable, the progressive nature of HFrEF, often silent, renders clinical stability a misleading situation, especially if diseaseContinue reading “Mildly symptomatic heart failure with reduced ejection fraction: diagnostic and therapeutic considerations”

Could artificial intelligence help treat heart failure?

Harnessing cutting-edge technologies could bring new hope for people with heart and circulatory disease. In the first of a new series, Sarah Brealey learns how artificial intelligence could help treat heart failure. Using artificial intelligence to make treatment predictions We’re funding Dr Declan O’Regan and his colleagues at Imperial College London to see if artificialContinue reading “Could artificial intelligence help treat heart failure?”

Echocardiograms Detail COVID-19’s Effects on the Heart

Harlan M. Krumholz, MD, SM reviewing Szekely Y et al. Circulation 2020 May 29 Right ventricular dilation and left ventricular diastolic impairment seem the most common findings from this small series. Early on in the COVID-19 pandemic, we realized that the heart could be involved. Information is still emerging about the spectrum of cardiac disease. Investigators have now reportedContinue reading “Echocardiograms Detail COVID-19’s Effects on the Heart”

The Cardiovascular Impact of COVID-19

An overview of the cardiac and vascular impacts of Coronavirus, including STEMI, stroke, VTE, shock, heart failure, myocarditis and arrhythmias. It was originally thought novel coronavirus (COVID-19, SARS-CoV-2) was primarily a respiratory disorder, but as larger numbers of patients contracted the virus, it quickly became clear it has many physiological manifestations. The impact of COVID-19 goes wellContinue reading “The Cardiovascular Impact of COVID-19”

Frequent Coffee Consumption Lowers Chance of Arrhythmias

New study aims to address the myths and anxiety around caffeine consumption among heart rhythm patients May 28, 2020 – A recent study revealed that drinking a couple of cups of coffee per day does not lead to a greater risk of arrhythmias. This potentially debunks a common myth that consuming caffeine in coffee andContinue reading “Frequent Coffee Consumption Lowers Chance of Arrhythmias”
