To identify an early, simple, noninvasive predictor of left main (LM) or 3-vessel disease (3-VD), we retrospectively studied clinical variables on admission in 310 patients with acute coronary syndromes with non-ST-segment elevation. Univariate analysis indicated that many factors were related to LM/3-VD. Multivariate analysis showed that ST-segment elevation in lead aVR of >/=0.5 mm was the strongest predictor of LM/3-VD, followed by positive troponin T (odds ratio 19.7, p <0.001, and odds ratio 3.08, p = 0.048, respectively). ST-segment elevation in lead aVR of >/=0.5 mm and positive troponin T identified LM/3-VD with sensitivities of 78% and 62%, specificities of 86% and 59%, positive predictive values of 57% and 26%, and negative predictive values of 95% and 87%, respectively (p <0.05). Our findings suggest that in patients with non-ST-segment elevation acute coronary syndromes, ST-segment elevation in lead aVR of >/=0.5 mm and positive troponin T on admission (especially the former) are useful predictors of LM/3-VD.

DESCRIPTION OF THE CLINICAL AND RADIOLOGICAL CHARACTERISTICS OF PULMONARY EMBOLISM IN COVID-19 VERSUS NON COVID-19 PATIENTS: A MULTICENTRIC CROSS-SECTIONAL STUDY OVER A 24-MONTH PERSPECTIVE.

Background: COVID-19 is associated with intense systemic inflammation and abnormal coagulation profile leading to an increased incidence of pulmonary embolism (PE). This study investigates whether PE in COVID-19 patients has different clinical, laboratory and radiological characteristics when compared to traditional PE in COVID negative patients.
Methods: We conducted an observational, multicentric, cross-sectional study on consecutive patients diagnosed with PE at admission or during hospital stay from February 21 2019 to February 20 2021.

Bisphenols may negatively impact human health. In this study, we propose the use of HPLC-FLD for the simultaneous determination of bisphenols in pericardial fluid samples collected from patients with coronary artery disease undergoing coronary artery bypass surgery. For sample preparation, a fast, simple, and "green" DLLME method was used, achieving mean recovery values in the range of 62%-98% with relative standard deviations between 2% and 6% for all analytes.

High-sensitivity cardiac troponins are considered a gold standard for diagnosing acute myocardial infarction and myocardial injury. However, the occurrence of false positives needs to be kept in mind. We describe the clinical challenges in diagnosing a 45-year-old woman who repeatedly presented to the emergency department with atypical chest pain and extremely elevated high sensitivity troponin I (HsTnI), despite normal imaging including cardiac MRIs and invasive coronary angiograms, on multiple occasions.
