Assessment of skeletal muscle fatigue of road maintenance workers based on heart rate monitoring and myotonometry
2006
Abstract Objective This research work is dedicated to occupational health problems caused by ergonomic risks. The research object was road building industry, where workers have to work very intensively, have long work hours, are working in forced/constrained work postures and overstrain during the work specific parts of their bodies. The aim of this study was to evaluate the work heaviness degree and to estimate the muscle fatigue of workers after one week work cycle. The study group consisted of 10 road construction and maintenance workers and 10 pavers aged between 20 and 60 years. Methods Physical load were analyzed by measuring heart rate (HR), work postures (OWAS) and perceived exertio…
Spontaneous plaque rupture visualized by intravascular ultrasound.
1994
An intravascular ultrasound examination was performed in order to evaluate an angiographically complicated lesion. Intravascular ultrasound was able to demonstrate spontaneous plaque rupture in a patient with recent acute subendocardial infarction. The inconclusive angiographic appearance was clarified by the intravascular examination and led us to conclude that the myocardial infarction was due to plaque rupture with subsequent thrombotic occlusion, which had spontaneously resolved by the time of the study.
Prognostic value of blood lactate in critically ill patients
1984
Hyperlactatemia is frequently observed in critically ill patients. A correlation of blood lactate concentrations and outcome of patients has been proven in circulatory shock, circulatory arrest, acute myocardial infarction, acute hypnotic drug poisoning and severe pancreatitis. However, the prognostic relevance of hyperlactatemia yields from statistical examinations in larger groups of patients. It should not be misused as a reliable prognostic sign in the individual patient, but is of high value in comparing groups of patients. In individual patients, hyperlactatemia is a useful indicator pointing to the severity of illness and to superimposed complications. Blood lactate is of considerabl…
Short‐term changes in left and right systolic function following ferric carboxymaltose: a substudy of the Myocardial‐IRON trial
2020
Funding: This work was supported in part by an unrestricted grant from Vifor Pharma and Proyectos de Investigación de la Sección de Insuficiencia Cardiaca 2017 from Sociedad Española de Cardiología. The mechanisms underlying the beneficial effect of ferric carboxymaltose (FCM) in patients with heart failure (HF) and iron deficiency (ID) have not been completely characterized. The Myocardial-IRON trial was a double-blind, randomized trial that evaluated myocardial iron repletion following FCM vs. placebo in 53 patients with HF and ID. In this post hoc analysis, we evaluated whether treatment with FCM was associated with cardiac magnetic resonance changes in left and right ventricular functio…
Coronary microvascular dysfunction
2020
Patients with coronary microvascular dysfunction (CMVD) represent a widespread population and despite the good prognosis, many of them have a poor quality of life with strong limitations in their daily activities because of the angina symptoms. This article summarizes the most frequent clinical presentation pictures like stable and unstable microvascular angina. Main risk factors are discussed, followed by the latest updates on the subject about different pathogenic hypotheses, diagnosis and treatment. Not very well understood microvascular alterations, like slow flow phenomenon and no reflow are discussed and both prognosis and the impact of the disease in the quality of life are analyzed.
Are Kawasaki Disease and Pediatric Multi-Inflammatory Syndrome Two Distinct Entities? Results from a Multicenter Survey During SARS-CoV-2 Epidemic in…
2020
Background: There is mounting evidence on the existence of a childhood multi-inflammatory syndrome related to SARS-CoV-2, sharing similarities with Kawasaki Disease (KD). Methods: On April 24th,2020 the Rheumatology Study Group of the Italian Pediatric Society launched a survey to enroll patients diagnosed with KD or KD-like disease. Classification was: 1) classical and incomplete KD, named Kawasaki Disease Group (KDG); 2) KD-like multi-inflammatory syndrome, named KawaCOVID Group (KCG). Demographic, clinical, and laboratory data, treatment information, and patients’ outcome were collected in an online anonymized database (RedCAPO). Chi square test or exact Fisher test and non parametric W…
Cardiac complications in thalassemia: noninvasive detection methods and new directions in the clinical management.
2004
The natural history of thalassemia has shown substantial change during these years. This applies for each aspect of the pathology (for example, endocrinological, hepatological and psychological) and also for the pathology that has presented and still presents the main cause of death: myocardial dysfunction. In this review, the pathophysiology of cardiac complications, possible role of myocarditis, new knowledge on pathogenesis, and noninvasive detection methods for iron overload in the heart are pointed out. Prophylaxis of cardiomyopathy and new therapy strategies of myocardial dysfunction, including the impact of the new chelation treatment, are discussed.

1232 Acute myocarditis: prognostic role of speckle tracking echocardiography and cardiac magnetic resonance
2020
Abstract Background Myocarditis is an inflammatory disease of the myocardium predominantly caused by infection with subsequent immunological response. Cardiac magnetic resonance (CMR) is the currently best imaging modality to confirm a suspected diagnosis of myocarditis. Conventional echocardiography can detect regional or global wall motion abnormalities but it could also be negative. Speckle tracking echocardiography can help to identify subtle systolic dysfunction, in patients with myocardits and apparently negative echocardiogram. Purpose the aim of this study was to identify cardiac imaging parameters predictive of cardiovascular events in patients with acute myocarditis. Methods a pro…
Cardiac magnetic resonance in the diagnosis of the unusually detected acute myocarditis in the young people: a case report
2021
Myocarditis is among the causes of arrhythmic sudden cardiac death (SCD) in young athletes, with viral infection being the most common cause worldwide. Myocarditis recently has been reported as one of the cardiac complications of coronavirus disease 2019 (COVID-19) in athletes. Here we present a case of a 20-year-old male recreational soccer player with an episode of loss of consciousness in the context of respiratory infection. The patient reports having woken up with symptoms of an upper respiratory tract infection, and after playing a soccer match, he developed dizziness and a headache. He then suffered vasovagal syncope without loss of sphincter control. Physical examination, heart ausc…
