Úrazy elektrickým proudem představují závažné zdravotní riziko s širokým spektrem následků, od téměř bezpříznakových stavů až po závažné život ohrožující komplikace. Tyto komplikace závisí na faktorech jako je napětí, proud, odpor tkání a délka expozice. Zásah elektrickým proudem vyžaduje multidisciplinární přístup zahrnující urgentní medicínu, interní medicínu a v některých případech popáleninovou a traumatologickou péči. Tento přehledový článek shrnuje současná doporučení pro diagnostiku a léčbu pacientů po zásahu elektrickým proudem, s důrazem na internistický pohled a řešení pacientů, kteří nejsou směrováni do popáleninových center.
Electrocution poses a serious health risk with a wide range of consequences, from mild to life-threatening complications. These effects depend on factors like voltage, current, tissue resistance, and duration of exposure. Electrocution injuries require a multidisciplinary approach involving emergency medicine, internal medicine, and, in some cases, burn and trauma care. This review summarizes current recommendations for diagnosing and treating patients after electrocution, with an emphasis on the role of the internist and the management of patients not directed to burn centers.

BACKGROUND: Secretoneurin (SN) is a neuropeptide with potential utility as a biomarker of cardiovascular episodes. The main effect of SN is mediated through its inhibition of calmodulin-dependent kinase II (CaMKII), which influences calcium handling. We aimed to associate the levels of SN in plasma with different causes of heart failure. METHODS: We prospectively enrolled consecutive patients with ischaemic (ICM) and dilated (DCM) cardiomyopathy from the outpatient heart failure clinic and healthy individuals. SN was analysed from venous blood by use of the ELISA method. SN plasma levels were compared in DCM, ICM and healthy individuals with non-parametric tests. RESULTS: A total of 53 patients (81.1% male, 18.9% female; mean age 67.9 ± 12.6 years) and 34 healthy individuals (38% male, 62% female) were included in the analysis. Plasma SN levels were significantly higher in the dilated cardiomyopathy (38.8 ± 27 pmol/L) as compared with the ischaemic cardiomyopathy (19.7 ± 22.6 pmol/L) group (P = 0.006). There was no significant difference between females vs. males (27.1 ± 23 vs. 25.5 ± 26.2 pmol/L, P = NS). Plasma SN levels allowed DCM and ICM to be differentiated with 88% sensitivity and 61% specificity (P = 0.007), the cut of value is 13.3 pmol/L. Plasma SN levels differed significantly between healthy volunteers and both ICM (P < 0.0001) and DCM (P = 0.049). Plasma SN levels did not differ according to age and were not associated with comorbidities, left ventricular ejection fraction, heart failure medication, troponin, creatinine, or natriuretic peptide plasma levels. CONCLUSION: Plasma secretoneurin levels differed significantly in DCM vs. ICM, being higher in the former. Based on plasma SN levels, discrimination between DCM and ICM might be possible. Healthy individuals produce higher SN plasma levels than stable HFrEF patients.

A number of microRNAs are involved in the pathophysiological events associated with heart disease. In this review, we discuss miR-21, miR-1, miR-23a, miR-142-5p, miR-126, miR-29, miR-195, and miR-499 because they are most often mentioned as important specific indicators of myocardial hypertrophy and fibrosis leading to heart failure. The clinical use of microRNAs as biomarkers and for therapeutic interventions in cardiovascular diseases appears highly promising. However, there remain many unresolved details regarding their specific actions in distinct pathological phenomena. The introduction of microRNAs into routine practice, as part of the cardiovascular examination panel, will require additional clinically relevant and reliable data. Thus, there remains a need for additional research in this area, as well as the optimization and standardization of laboratory procedures which could significantly shorten the determination time, and make microRNA analysis simpler and more affordable. In this review, we aim to summarize the current knowledge about selected microRNAs related to heart failure, including their potential use in diagnosis, prognosis, and treatment, and options for their laboratory determination.
