New research finds that low fitness levels and older age are strong and independent risk factors for heartbeat irregularities, or arrhythmias*, in healthy adults. These arrhythmias were previously thought to be harmless, but are now considered to be an indicator of future cardiovascular risk (1,2) 

The results support the introduction of age-based arrhythmia screening in over 50s, to allow for early intervention before symptoms arise to alter the trajectory of disease  

There was a particularly strong association between lower aerobic fitness and risk of frequent and complex atrial arrythmias, highlighting the critical role of physical fitness in preserving the electrical stability of the heart  

It’s often mistaken for a heart attack, but Takotsubo cardiomyopathy – previously known as Broken Heart syndrome – is a serious and sometimes fatal heart condition increasingly reported in intensive care units (ICUs). Yet without a clear clinical pathway in ICUs, it’s often missed, putting critically ill patients at risk. New research from the University of South Australia shows that using electrocardiogram (ECG) patterns and blood markers could provide an early warning system for Takotsubo Syndrome in ICU patients.

The Society for Cardiovascular Angiography & Interventions (SCAI) has published a new position statement that provides best-practice guidance for the treatment of patent ductus arteriosus (PDA) using transcatheter occlusion (tcPDA) in premature infants. Published in JSCAI, “SCAI Position Statement on Transcatheter Occlusion of Patent Ductus Arteriosus in Premature Infants” offers a practical framework in four key areas: Patient selection criteria, technical and procedural best practices, operator training benchmarks, and institutional infrastructure needs.
