The Multifaceted Interplay between Atrial Fibrillation and Myocardial Infarction: A Review
2021
International audience; This review was conducted to emphasize the complex interplay between atrial fibrillation (AF) and myocardial infraction (MI). In type 1 (T1) MI, AF is frequent and associated with excess mortality. Moreover, AF after hospital discharge for T1MI is not rare, suggesting the need to improve AF screening and to develop therapeutic strategies for AF recurrence. Additionally, AF is a common trigger for type 2 MI (T2MI), and recent data have shown that tachyarrhythmia or bradyarrhythmia could be a causal factor in, respectively, 13–47% or 2–7% of T2MI. In addition, AF is involved in T2MI pathogenesis as a result of severe anemia related to anticoagulants. AF is also an unde…
Heart rate variability as predictor of mortality in sepsis: A systematic review.
2018
Background Autonomic dysregulation is one of the recognized pathophysiological mechanisms in sepsis, generating the hypothesis that heart rate variability (HRV) can be used to predict mortality in sepsis. Methods This was a systematic review of studies evaluating HRV as a predictor of death in patients with sepsis. The search was performed by independent researchers in PubMed, LILACS and Cochrane, including papers in English, Portuguese or Spanish, indexed until August 20th, 2017 with at least 10 patients. Study quality was assessed by Newcastle-Ottawa Scale. To analyze the results, we divided the articles between those who measured HRV for short-term recordings ( 1 hour), and those who did…
Comorbidities, Fragility, and Quality of Life in Heart Failure Patients With Midrange Ejection Fraction.
2018
Objective: To assess the effects of comorbidities, fragility, and quality of life (QOL) on long-term prognosis in ambulatory patients with heart failure (HF) with midrange left ventricular ejection fraction (HFmrEF), an unexplored area. Patients and Methods: Consecutive patients prospectively evaluated at an HF clinic between August 1, 2001, and December 31, 2015, were retrospectively analyzed on the basis of left ventricular ejection fraction category. We compared patients with HFmrEF (n=185) to those with reduced (HFrEF; n=1058) and preserved (HFpEF; n=162) ejection fraction. Fragility was defined as 1 or more abnormal evaluations on 4 standardized geriatric scales (Barthel Index, Older A…
Giant right atrial myxoma: A rare cause of cardiovascular collapse
2019
We report the case of a patient with a giant right atrial myxoma that remained clinically silent until it almost completely obliterated the right atrium, prolapsed into the right ventricle and obstructed the tricuspid valve inflow. This case illustrates the importance of rapid surgical intervention in the setting of acute heart failure caused by tumor masses obliterating heart valves or cardiac chambers.
Reappraisal of European guidelines on hypertension management: A European Society of Hypertension Task Force document

Clinical outcome of critically ill, not fully recompensated, patients undergoing MitraClip therapy
2014
Aims As periprocedural risk is low, MitraClip implantation is often performed in critically ill, not fully recompensated patients, who are in NYHA functional class IV at the time of the procedure, to accelerate convalescence. We herein sought to evaluate the procedural and 30-day outcome of this patient group. Methods and results A total of 803 patients undergoing MitraClip implantation were included in the German Mitral Valve Registry, and 30-day outcomes were prospectively assessed. Patients were separated based on NYHA functional class [(NYHA IV (n = 143), III (n = 572), and I/II (n = 88)]. No difference was noted in co-morbities and echocardiographic parameters of LV function between gr…
Factors associated with the subjective health complaints among adolescents: Results from the ASSO Project
2019
Objectives. Subjective health complaints (e.g. headache and feeling low) are common among adolescents. The objective of this study was to identify the factors associated with the subjective health of adolescents from a population-based point of view. Material and methods. A sample of 712 students was recruited within the web-based Project ASSO (Adolescents and Surveillance System for the Obesity prevention), funded by the Italian Ministry of Health and piloted in Palermo. A 0-100 quantitative score (arbitrarily named "psychosomatic malaise index") based on the frequency of occurrence of seven subjective health complaints was created and used as outcome; socio-demographic characteristics, me…
Medical simulation for ICU staff: does it influence safety of care?
2016
Dear Editor, We read with great interest the article by Garrouste-Orgeas et al. entitled ‘‘Understanding medical errors and adverse events in ICU patients’’ [1]. In particular, two sentences caught our attention: ‘‘medical errors are the consequence of multiple actions of a whole chain of organizational and humans interaction...’’ and ‘‘leadership, trust, respect, open communication, non-punitive actions and coordination of behavior are essential for a multidisciplinary ICU team to provide safe care’’. In a teamworking setting like the ICU, shared knowledge and non-technical skills are pivotal to deliver a high quality of care and to reduce medical errors. Medical simulation has been demons…
Poincaré surface profile. Novel non-invasive method to detect preferential ventricular response during atrial fibrillation
2007
The strategy of rate control during atrial fibrillation (AF) essentially deals with efforts to utilize and adjust the filtering properties of the atrioventricular (AV) node, allowing AF to continue and ensure that ventricular rate is controlled. In this work, a new tool based on the 3D Poincare plots is developed for the characterization of the ventricular response (VR) and the clinical evaluation of rate control therapies. Mechanisms underlying atrioventricular conduction during AF remain unclear. The role of the dual pathway AV nodal electrophysiology and the effects of the AV node modifications are still being an incognita. RR interval clusters exhibiting harmonic behaviour have been qua…
Basics of Image Interpretation in Interventional Neuroradiology
2011
The majority of patients with cerebral vascular diseases, demanding neuroradiological interventions are those, who present with potential life-threatening spontaneous intracranial/intracerebral haemorrhages due to cerebral aneurysms or/and arteriovenous malformations (AVMs) or with cerebral infarction due to intra-arterial thrombi in cerebral arteries. Neuroradiological procedures (interventional neuroradiology) (IN), always, performed in general anaesthesia can be divided into occluding and opening interventions.
