The role of extensive diagnostic work-up in young athletes and non-athletes with complex ventricular arrhythmias

Ventricular tachyarrhythmias (VA) represent the first cause of death in athletes. The difference between electroanatomic substrate in athletes and non-athletes with complex VA is unknown.

Publication date: Available online 7 October 2019Source: Pathology - Research and PracticeAuthor(s): Dominik Gross, Christina LaursAbstractThe Jewish pathologist Carl Julius Rothberger (1871–1945) is undoubtedly one of the most important representatives of his field. His studies on atrial fibrillation, the bundle branch block and arrhythmia perpetua in particular secured him a place in medical history. Rothberger also gave the name to an agar used to prove the neutral red reduction of salmonella (Rothberger-Scheffler agar).While Rothberger’s name is well known in pathology, his biography and his experiences of ...

ConclusionsThese findings provided strong evidences that TGD intervention ameliorated interstitial fibrosis, myocyte hypertrophy and gap junction expression in the IBZ, attenuated left ventricular remodeling and dysfunction, and reduced vulnerability to tachyarrhythmia. TGD inhibited IBZ remodeling by its inhibition effect on myofibroblasts differentiation.

For both diseases, CS is related to a worse long term outcome. Outcome of CS has not been studied in a direct comparison of MI patients and TTS patients.Methods and ResultsMortality and cardiovascular complications were compared in patients presenting with CS b...

ConclusionThe IECF is simple, particularly at reoperations, in borderline patients and those needing concomitant intracardiac procedures. Early results are promising. These patients need constant surveillance.

The transient receptor potential ankyrin 1 (TRPA1) channel is a calcium-permeable nonselective cation channel in the plasma membrane that belongs to the transient receptor potential (TRP) channel superfamily. Recent studies have suggested that the TRPA1 channel plays an essential role in the development and progression of several cardiovascular conditions, such as atherosclerosis, heart failure, myocardial ischemia–reperfusion injury, myocardial fibrosis, arrhythmia, vasodilation, and hypertension. Activation of the TRPA1 channel has a protective effect against the development of atherosclerosis. Furthermore, TRPA1 c...

Publication date: Available online 16 October 2019Source: Respiratory Physiology &NeurobiologyAuthor(s): Jacopo P. Mortola, Domnica Marghescu, Rosmarie Siegrist-Johnstone, Elizabeth MatthesAbstractIt is known that a mental attention task (MAT) can modify the magnitude of the increase in instantaneous heart rate (HR) with inspiration, or Respiratory Sinus Arrhythmia (RSA). Here, we asked whether the RSA changes were mediated by the changes in HR, breathing frequency (f) or HR/f (‘breathing specific heart rate’). This latter reflects the degree of coupling between pulmonary blood and air flows, the optimizati...

Mind-reading exoskeletons, digital tattoos, 3D printed drugs, RFID implants for recreational purposes: mindblowing innovations come to medicine and healthcare almost every single day. We shortlisted some of the greatest ideas and developments that could give us a glimpse into the future of medicine, but we found so many that we had trouble fitting them into one article. Here are the first ten spectacular medical innovations to watch for. 1) Mixed reality opens new ways for medical education Augmented, virtual, and mixed reality are all technologies opening new worlds for the human senses. While the difference between...

ConclusionAF ablation using a standardized workflow resulted in low procedure times and variability, with minimal fluoroscopy exposure. Long-term freedom from atrial arrhythmia recurrence was high in both PAF and PsAF populations.

AbstractIntroductionMyocardial infarction (MI) is associated with an increase in subsequent heart failure (HF), recurrent ischemic events, sudden cardiac arrest, and ventricular arrhythmias (SCA ‐VA). The primary objective of the study to determine the role of intercurrent HF and ischemic events on the development of SCA‐VA following first type I MI.Methods and resultsA retrospective cohort study of patients experiencing first type 1 MI in Olmsted County, Minnesota (2002 ‐2012) was conducted by identifying patients using the medical records linkage system (Rochester epidemiology project). Patients aged ≥18 years w...
