Takotsubo Syndrome: A Recurrent Disease?

Conclusions: Female gender, time from the first episode of the syndrome, low BMI and midventricular obstruction were reported as potential predictors of TTS recurrence.Resumo Fundamento: A s índrome de Takotsubo (STT) é caracterizada por uma disfunção sistólica temporária do ventrículo esquerdo (VE) relacionada a um evento estressante. No entanto, os fatores associados à sua recorrência ainda não estão bem estabelecidos. Objetivo: Analisar os principais fatores associados à recorrência da STT. Métodos: Uma revisão sistemática foi realizada usando o modelo PRISMA. Foram incluídos estudos observacionais, publicados entre janeiro de 2008 e outubro de 2017, que apresentaram uma taxa de recorrência de pelo menos 3% e/ou 5 ou mais pacientes com recidiva e que preench eram pelo menos 80% dos critérios STROBE. Resultados: Seis artigos atenderam aos critérios para esta revisão sistemática. A taxa de recorrência variou de 1 a 3,5% ao ano (taxa de recorrência global 3,8%). Um estudo associou maior taxa de recorrência ao sexo feminino, quatro relataram o tempo entre o primeiro e o segundo episódio, um estudo associou o índice de massa corporal (IMC) e a hipercontratilidade da parede anterior média do VE a uma maior taxa de recorrência. Não foi determinada associação entre re...

The Brugada syndrome is an inherited channelopathy that alters the main transmembrane ion currents that constitute the cardiac action potential. These changes not only modify the resting electrocardiogram but also predispose patients to develop malignant ventricular tachyarrhythmias that can lead to syncope, cardiac arrest, and sudden cardiac death. This syndrome is responsible for nearly 20% of all sudden cardiac deaths in patients with structurally normal hearts and up to 12% of all sudden cardiac deaths. Brugada syndrome is diagnosed by its characteristic electrocardiogram consisting of a coved-type ST-segment elevation...

Particulate matter poses health risk to developing organisms. To investigate particulate matters with a diameter smaller than 2.5 um (PM2.5)-induced developmental cardiotoxicity, fertile chicken eggs were exposed to PM2.5 via air cell injection at doses of 0.05, 0.2, 0.5, 2, and 5 mg/egg kg. Morphological changes in the embryonic day four (ED4) and hatchling hearts were assessed with histological techniques. Heart rates of hatchling chickens were measured with electrocardiography. The protein expression levels of nuclear factor kappa-light-chain-enhancer of activated B cells p65 (NF-kb p65), inducible nitric oxide synthase...

CONCLUSION: A graded submaximal exercise test without ECG but with symptom monitoring and conservative heart rate and perceived exertion endpoints may facilitate safe exercise intensities early after stroke. Symptom-limited exercise testing with ECG is still recommended when progressing to higher-intensity exercise. IMPACT: Concerns about cardiovascular risk are a barrier to physical therapists implementing aerobic exercise in stroke rehabilitation. This study showed that, in the absence of access to exercise testing with ECG, submaximal testing with conservative heart rate and perceived exertion endpoints and symptom...

Written by Pendell MeyersA man in his sixties with no prior history of CAD presented with fluctuating central chest pain that started the night before presentation, then went away, then woke him up from sleep the morning of presentation. The pain was 10/10 on arrival, with SOB. Although he also had some nasal drip and sore throat, he had no cough or fevers (this occurred during peak COVID).Here is his triage ECG:What do you think?Normal P-waves would have upright morphology in the inferior leads (especially lead II) and usually biphasic (up-down) morphology in V1. These p-waves are negative in almost all leads except for a...

CONCLUSION: We report the successful management of anesthesia without lethal arrhythmia in a patient with ARVC and an ICD. An adequate amount of analgesia should be administered during general anesthesia to maintain adequate anesthetic depth and to avoid stress and pain. PMID: 32473832 [PubMed - as supplied by publisher]

Scilingo The non-invasiveness of photoplethysmographic (PPG) acquisition systems, together with their cost-effectiveness and easiness of connection with IoT technologies, is opening up to the possibility of their widespread use. For this reason, the study of the reliability of PPG and pulse rate variability (PRV) signal quality has become of great scientific, technological, and commercial interest. In this field, sensor location has been demonstrated to play a crucial role. The goal of this study was to investigate PPG and PRV signal quality acquired from two body locations: finger and wrist. We simultaneously acquire...
