Article Synopsis
- The study aimed to improve the assessment of left ventricular wall motion abnormalities (WMAs) by introducing new measurement methods and comparing them to traditional scoring indices like the wall motion score index (WMSI).
- Researchers analyzed 140 echocardiograms from patients with serious heart issues, focusing on various metrics for measuring wall motion, including the percentage of akinesia and hypokinesia.
- Results showed that the new methods demonstrated low inter- and intra-observer variability, making them reliable alternatives for evaluating WMAs in echocardiographic exams.
Article Synopsis
- The study compares ECG changes over 30 days between female patients with anterior STEMI (a type of heart attack) and female patients with Takotsubo syndrome (a stress-induced heart condition).
- It found that T wave inversion patterns were similar in both groups, but ST elevation was more common in STEMI, while QT prolongation was less frequent.
- Overall, the ECG patterns suggest that TTS may show a temporary ischemic-like pattern, indicating similarities in heart stress responses between these conditions.

Article Synopsis
- The study investigates the levels of cardiac troponin T (hs-cTnT) and troponin I (hs-cTnI) during and after different durations of myocardial ischaemia (lack of blood flow) in both rats and human patients with heart attacks (STEMI).
- Results show that after short periods of ischaemia, hs-cTnI and hs-cTnT levels rise similarly, leading to a ratio of around 1, indicating non-necrotic cTn release.
- In contrast, longer ischaemia that results in heart tissue damage shows a significantly higher hs-cTnI/hs-cTnT ratio (3.6-5.5),
Background: Abnormal electrocardiogram (ECG) has been associated with poor outcome in patients hospitalized for COVID-19. However, the independent association between admission ECG and the risk of a poor outcome remains to be established. Our aim was to determine if abnormal admission ECG predicts treatment at intensive care unit or in-hospital death within 30 days in patients hospitalized for COVID-19.

- A study was conducted to compare the electrocardiogram (ECG) results of Takotsubo syndrome (STE-TS) patients with those diagnosed with ST elevation myocardial infarction (STEMI), ensuring balanced age and sex groups and considering the specific locations of blockages in STEMI patients.
- The analysis included 104 STE-TS patients matched to 274 STEMI patients, revealing that STE-TS ECGs closely resembled those of patients with left anterior descending artery (LAD) STEMI, but with significantly less occurrence of reciprocal ST depression.
- Findings indicated that while certain ST segment changes were predictive of life-threatening ventricular arrhythmia and death in LAD STEMI patients, these changes did not demonstrate predictive value
Purpose: This meta-epidemiological study aimed to systematically review case reports regarding sports nutrition supplements and adverse events (AEs), specifically addressing the issue of causality assessments.
Methods: Through a systematic literature search we identified all published case reports of AEs associated with sports nutrition supplements between 1 January 2008 and 1 March 2019. Data regarding AEs, suspected supplements, relevant causality assessment factors and the reporting of clinical reasoning and/or systematic causality assessment methods were extracted.
Article Synopsis
- Chloroquine was initially considered a potential treatment for COVID-19 but is now largely abandoned due to insufficient benefits and serious safety concerns.
- This study compared 20 COVID-19 patients treated with chloroquine to 40 matched controls, analyzing their medical records and heart health indicators.
- Results showed no significant differences in heart injury or failure between the two groups, but the authors advise against using chloroquine for COVID-19 outside clinical trials, due to its ineffectiveness and potential for dangerous heart arrhythmias.
Aims: The risk of life-threatening ventricular arrhythmias (LTVA) has been reported to be lower in Takotsubo syndrome (TS) compared with ST-elevation myocardial infarction (STEMI). However, the extent to which these differences relate to the fact that most patients with TS are women (who have a lower risk of LTVA) and a relatively larger proportion of patients with STEMI are men is incompletely understood. We aimed to investigate the risk of LTVA or death in sex-matched and age-matched patients with TS, anterior STEMI, and non-anterior STEMI.

- Takotsubo syndrome (TS) is a serious heart failure condition, with limited knowledge on risk factors for severe outcomes and no established high-risk ECG criteria.
- A study using data from the Swedish Angiography and Angioplasty Registry tracked patients with TS to identify ECG patterns linked to in-hospital complications.
- Results showed that T-wave inversion in ECG was often seen in TS patients and was associated with a reduced risk of major adverse cardiac events, particularly ventricular tachycardia or fibrillation.
Article Synopsis
- - Takotsubo syndrome (TS) is an acute heart failure condition that often resolves on its own, but can lead to serious complications and is hard to differentiate from a heart attack early on.
- - A systematic review outlines the clinical management of TS, covering its diagnosis, treatment after diagnosis, and recovery phase.
- - The review suggests avoiding unnecessary treatments due to TS's self-limiting nature and emphasizes monitoring patients closely, avoiding inotropic drugs, and considering mechanical assist devices for those with severe symptoms.
Aim: New strategies are required to increase physical activity and improve metabolic profiles in children with obesity. We studied the effect of whole body vibration (WBV) on children with obesity on biochemical markers of energy and bone metabolism, anthropometric measurements, muscle parameters and calcaneal bone mineral density (BMD).
Methods: This was a randomised, prospective, controlled study of 30 children with a median age of 13 years (range 7-17) at Queen Silvia Children's Hospital, Gothenburg, Sweden, from 2013 to 2015.
