Admission electrocardiography (ECG) in heart failure (HF) patients provides important diagnostic information; however, there are limited data regarding the prognostic significance of ECG parameters for predicting cardiac events (CEs). The ECGs of 246 patients admitted with acute HF were evaluated for heart rate, rhythm, QRS and ST-T wave abnormalities, QTc duration, QT peak corrected (QTpc), T amplitude, and axis. The end points included rehospitalization for a CE or death during 30-day follow-up. There were 71 (29%) patients with CEs. In patients with CEs, atrial fibrillation (AF) was observed more frequently (27% vs 13%, respectively; P=.009) and QTpc was shorter (370+/-43 vs 386+/-44 ms, respectively; P=.020). Multivariate logistic regression analysis revealed that QTpc

Improvement in Atrial Fibrillation Detection by Pulse Checking of Patients with Non-Cardioembolic Stroke in Rehabilitation Hospitals: The ESCORT Study.
J Nippon Med Sch
January 2025
Department of Neurology, Nippon Medical School Hospital.
Background: Rehabilitation therapists are sometimes unaware of the possibility of undiagnosed atrial fibrillation (AF) and the importance of AF detection. Thus, we aimed to increase awareness among rehabilitation therapists of the importance of AF detection at rehabilitation hospitals during regular pulse checks of patients with ischemic stroke.
Methods: In this multicenter prospective observational study, we enrolled patients with noncardiac stroke.
Survival after aluminum phosphide poisoning with cardiotoxicity: a case report.
J Med Case Rep

Department of Internal Medicine, Woldia Comprehensive Specialized Hospital, Woldia, Ethiopia.
Introduction: Aluminum phosphide is a cheap and commonly used rodenticide that is also an effective solid fumigant and frequently used for grain preservation. The pill contains around 44% inert elements (ammonium carbonate) to avoid disintegration of the tablet, while the rest (about 56%) is aluminum phosphide. Because it is freely available on the market, it is one of the commonly used agents for self-poisoning in different parts of the developing world.

J Med Case Rep

Faculty of Healthcare Sciences, Eastern University of Sri Lanka, Chenkaladi, Sri Lanka.
Background: Naphthalene is an aromatic hydrocarbon that potentially produces methemoglobinaemia but rarely causes hemolysis, especially in children with underlying glucose-6-phosphate dehydrogenase deficiency. Although ingestion of a single moth ball by an older child may not be life threatening, it can be fatal if ingested by a toddler.
Case Presentation: A 2-year-old Singhalese boy developed acute severe hemolysis and methemoglobinaemia following ingestion of a mothball.
Periannular extension of infective endocarditis with atrioventricular block successfully treated with antibiotic therapy after transcatheter aortic valve implantation: a case report.
Eur Heart J Case Rep
December 2024
Division of Cardiovascular Medicine, Department of Medicine, Jichi Medical University School of Medicine, 3311-1 Yakushiji, Shimotsuke 329-0498, Japan.
Background: Although transcatheter aortic valve implantation (TAVI) is performed for very elderly patients in whom surgical aortic valve replacement (SAVR) poses unacceptably high operative risk, some of these patients are ultimately forced to undergo open surgery when TAVI is complicated by infective endocarditis (IE). To our knowledge, there have been no reports of cases with periannular extension of IE and atrioventricular block successfully treated by antibiotics without valve replacement.
Case Summary: An 80-year-old Japanese man who had undergone TAVI developed IE with loss of consciousness on Day 39 after the procedure.
Value of ACEF-II Score in Predicting Major Adverse Cardiac Events in Patients With Non-ST-Segment Elevation Myocardial Infarction and Unstable Angina.

Cardiology Department, Bakırköy Dr Sadi Konuk Training and Research Hospital, Istanbul, Turkey.
Background: A score based on age, creatinine level, and ejection fraction as well as hematocrit value and the presence of emergency surgery (ACEF-II) has been proposed to have predictive value for risk stratification in cardiac surgery. This study aimed to evaluate its utility in patients with non-ST-segment elevation myocardial infarction and unstable angina (NSTEMI-ACS) to predict 1-year major adverse cardiac events (MACE).
Methods: In all, 768 patients with NSTEMI-ACS were enrolled in the study.
