[ST-elevation myocardial infarction caused by stent fracture: a case report].

Coronary stent fracture is an infrequent event, with an incidence ranging from 1% to 8%. In rare cases, this complication may result in acute occlusion of the affected coronary artery. We report the case of a patient who experienced acute coronary syndrome following a stent fracture implanted 3 years previously.

Telemedicine and Remote Management of Patients with Heart Failure: From Theory to Daily Practice.

Heart failure (HF) is responsible for a high number of hospitalizations, caused by a progressive worsening quality of life. Telemedicine allows for better management of patients' complex conditions, improving the care released. However, the risk of remaining at a testing stage often limits the integration of remote care in daily pathways for HF patients.

Symptoms-to-emergency-call timing delay in acute coronary syndrome before and during COVID-19: independent predictors and their impact on mortality.

Background: The COVID-19 pandemic severely impacted global health. The aim of this study was to compare predictors of symptoms-to-emergency-call timing delay in acute coronary syndrome (ACS) and their impact on mortality before and during the COVID-19 outbreak.

Methods: We collected sociodemographic, clinical data, procedural features, preadmission and intra-hospital outcomes of consecutive patients admitted for ACS in seventeen Italian centers from March to April 2018, 2019, and 2020.

The Incidence and Impact of In-Hospital Bleeding in Patients with Acute Coronary Syndrome during the COVID-19 Pandemic.

Aim: to explore the incidence and prognostic impact of in-hospital bleeding in patients presenting with ACS before and during the COVID-19 pandemic.

Methods: We evaluated in-hospital Thrombolysis In Myocardial Infarction (TIMI) major and minor bleeding among 2851 patients with ACS from 17 Italian centers during the first wave of the COVID-19 pandemic (i.

Myocardial injury in patients with SARS-CoV-2 pneumonia: Pivotal role of inflammation in COVID-19.

Aims: Infection by SARS-CoV-2 may result in a systemic disease and a proportion of patients ranging 15%-44% experienced cardiac injury (CI) diagnosed by abnormal troponin levels. The aim of the present study was to analyse the clinical characteristics of a large series of hospitalized patients for COVID-19 in order to identify predisposing and/or protective factors of CI and the outcome.

Methods And Results: This is an observational, retrospective study on patients hospitalized in two Italian centres (San Raffaele Hospital and Cremona Hospital) for COVID-19 and at least one high-sensitivity cardiac troponin (hs-cTnt) measurement during hospitalization.

Coronary artery disease in patients hospitalised with Coronavirus disease 2019 (COVID-19) infection.

Objective: Among patients with Coronavirus disease 2019 (COVID-19), coronary artery disease (CAD) has been identified as a high-risk condition. We aimed to assess the clinical outcomes and mortality among patients with COVID-19 according to CAD status.

Methods: We retrospectively analysed data from patients with COVID-19 admitted to the Cremona Hospital (Lombardy region, Italy) between February and March 2020.

Effects on QT interval of hydroxychloroquine associated with ritonavir/darunavir or azithromycin in patients with SARS-CoV-2 infection.

Introduction: Most of the drugs associations that have been used to treat patients with SARS-CoV-2 infection increase the risk of prolongation of the corrected QT interval (QTc).

Objective: To evaluate the effects of an association therapy of hydroxychloroquine (HY) plus ritonavir/darunavir (RD) or azithromycin (AZ) on QTc intervals.

Methods: At the beginning of COVID-19 pandemic patients admitted to our hospital were treated with the empiric association of HY/RD; one week later the therapeutic protocol was modified with the combination of HY/AZ.

NUV-Sensitive Silicon Photomultiplier Technologies Developed at Fondazione Bruno Kessler.

Different applications require different customizations of silicon photomultiplier (SiPM) technology. We present a review on the latest SiPM technologies developed at Fondazione Bruno Kessler (FBK, Trento), characterized by a peak detection efficiency in the near-UV and customized according to the needs of different applications. Original near-UV sensitive, high-density SiPMs (NUV-HD), optimized for Positron Emission Tomography (PET) application, feature peak photon detection efficiency (PDE) of 63% at 420 nm with a 35 um cell size and a dark count rate (DCR) of 100 kHz/mm².

Echocardiographic evaluation of diastolic dysfunction in young and healthy patients with psoriasis: A case-control study.

Psoriasis is a systemic inflammatory disease with a great prevalence in general population. The inappropriate activation of the cellular immune system has been hypothesized to be an independent cardiovascular risk factor, given the higher incidence of cardiovascular disorders in psoriatic patients. Echocardiographic abnormalities have been demonstrated too: the aim of our study was to evaluate the presence of preclinical cardiac dysfunction in a cohort of psoriatic patients without cardiovascular risk factors.

School and family-based interventions for promoting a healthy lifestyle among children and adolescents in Italy: a systematic review.

Aims: Cardiovascular diseases affect adult population but risk factors develop as a result of known or assumed behavior since childhood. In Italy, up to 22.2% of children are overweight, 10.

Measurements of 2D distributions of absorbed dose in protontherapy with Gafchromic EBT3 films.

A study of the response of EBT3 films to protons has been carried out with the aim of finding a simple modality to achieve dose images in which the effect of the film sensitivity dependence on radiation LET is amended. Light transmittance images (around 630 nm) were acquired by means of a CCD camera and the difference of optical density was assumed as dosimeter response. The calibration of EBT3 film was performed by means of protons of 173.

Noninvasive assessment of endothelial function: the classic methods and the new peripheral arterial tonometry.

The combination of risk stratification by assessment of conventional risk factors for cardiovascular disease (CVD) with not only a morphological assessment of vascular damage (such as carotid ultrasound examination) but also vascular function tests may be a useful strategy for the management of CVD and its related risk factors. Endothelial dysfunction is present in a great variety of pathological conditions: it is considered the first alteration of vascular function in atherosclerosis and one of the phenomena involved in the progression of heart failure. Assessing endothelial function with noninvasive methods could have a central role for evaluation of treatment, prognostic stratification, and pharmacological studies in CVD.

Mineralocorticoid receptor antagonist in heart failure: Past, present and future perspectives.

Aldosterone is involved in various deleterious effects on the cardiovascular system, including sodium and fluid retention, myocardial fibrosis, vascular stiffening, endothelial dysfunction, catecholamine release and stimulation of cardiac arrhythmias. Therefore, aldosterone receptor blockade may have several potential benefits in patients with cardiovascular disease. Mineralocorticoid receptor antagonists (MRAs) have been shown to prevent many of the maladaptive effects of aldosterone, in particular among patients with heart failure (HF).

Measurements of gamma dose and thermal neutron fluence in phantoms exposed to a BNCT epithermal beam with TLD-700.

Gamma dose and thermal neutron fluence in a phantom exposed to an epithermal neutron beam for boron neutron capture therapy (BNCT) can be measured by means of a single thermoluminescence dosemeter (TLD-700). The method exploits the shape of the glow curve (GC) and requires the gamma-calibration GC (to obtain gamma dose) and the thermal-neutron-calibration GC (to obtain neutron fluence). The method is applicable for BNCT dosimetry in case of epithermal neutron beams from a reactor because, in most irradiation configurations, thermal neutrons give a not negligible contribution to the TLD-700 GC.

Methods for dose measurements in small phantoms irradiated at BNCT epithermal column.

Suitable dosimeter methods have been proposed and tested, to measure the different dose contributions in small phantoms exposed to epithermal/thermal neutron beams designed for BNCT. One method is based on Fricke-gel dosimeter in small tubes of 2.8mm of external diameter, that allow determining profiles of gamma dose and of boron dose.

[New pharmacological approaches to ischemic heart disease].

Major steps have been made in the treatment of ischemic heart disease from the discovery of nitrates as antianginal medication to the techniques of percutaneous angioplasty. This incredible therapeutic progress has resulted in a reduced incidence of ischemic heart disease and related mortality and morbidity. However, statistical and epidemiological data indicate that in ischemic heart disease, despite the achievement of great success, there is a necessity for a further step toward treatment, considering the fact that the characteristics of this population are changing (increased prevalence of subendocardial infarction compared with classic transmural infarction, especially in the elderly population).
