Article Synopsis
- The study evaluates the effectiveness of low energy synchronous shock (LESS) in measuring shock impedance during subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation, focusing on its potential to predict the success of defibrillation testing (DFT).
- It finds a strong correlation between LESS and DFT impedance values, indicating that LESS can accurately reflect defibrillation success, especially in patients with higher body mass index (BMI).
- The analysis concludes that LESS impedance can serve as a useful intraoperative predictor for successful DFT, achieving good diagnostic accuracy with a specific cutoff value.
Ischemic cardiomyopathy (ICM) constitutes a major public health issue, directly involved in the prevalence and incidence of heart failure, ventricular arrhythmias (VA) and sudden cardiac death (SCD). Severe impairment of left ventricular ejection fraction (LVEF) is considered a high-risk marker for SCD, conditioning the criteria that determine an implantable cardiac defibrillator (ICD) placement in primary prevention according to current clinical guidelines. However, its sensitivity and specificity values for the prediction of SCD in ICM may not be highest.

We aimed to conduct a systematic review of the literature and summarize the performance of mobile health (mHealth) devices in diagnosing and screening for AF.
Methods And Results: We conducted a systematic search of MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials.
Objectives: This study was conducted in order to evaluate the usefulness of copeptin (a stable fragment of the precursor of arginine vasopressin) in the differential diagnosis of acute chest pain of probable coronary origin.
Material And Methods: The study includes 82 patients who were initially evaluated according to the protocol of a patient with suspected acute coronary syndrome (ACS) in our Emergency Department, including the determination of troponin and copeptin with specimens taken on admission (time 0) and at 6h.
Results: Statistically significant differences were observed in copeptin concentrations at time 0 among patients diagnosed with non-ST-segment elevation (NTEACS): 42.
