A bio-clinical approach for prediction of sudden cardiac death in outpatients with heart failure: The ST2-SCD score
2019
Sudden cardiac death (SCD) is one of the main modes of death in heart failure (HF) patients and its prediction remains a real challenge. Our aim was to assess the incidence of SCD at 5 years HF contemporary managed outpatients, and to find a simple prediction model for SCD.SCD was considered any unexpected death, witnessed or not, occurring in a previously stable patient with no evidence of worsening HF or any other cause of death. A competing risk strategy was adopted using the Fine-Gray method of Cox regressions analyses that considered other causes of death as the competing event.The derivation cohort included 744 consecutive outpatients (72% men, age 67.9 ± 12.2 years, left ventricular …
Mechanism of fatal air embolism after gastrointestinal endoscopy.
1998
Although venous air embolism is a known complication in medical practice in general, only a single case of upper gastrointestinal endoscopy complicated by venous air embolism with consecutive acute cardiovascular failure has so far been described in literature. Here we show that gastroscopy may be accompanied by massive, i.e. fatal venous air embolism. If a vessel in the gastrointestinal tract is exposed but does not collapse (in the case of a gastric ulcer, for example) air insufflated under pressure by the gastroscope may lead to a fatal air embolism. Our tests using a commercial gastroscope revealed that an overpressure of up to 43 kPa (kiloPascals) is reached without the rinsing functio…
Arrhythmic sudden cardiac death in a 3-year-old child with intimal fibroplasia of coronary arteries, aorta, and its branches
2001
Abstract We report an unusual case of “arrhythmic” sudden cardiac death in a 3-year-old child who died of ischemic myocardial lesions as a result of intimal fibroplasia of the coronary arteries. Also affected were the aorta and its major branches, whereas renal and mesenteric arteries, celiac trunk, and systemic veins were normal. Histopathologic examination showed severe concentric thickening of intima because of a proliferation of spindle-shaped cells (mesenchymal cells) set in an abundant extracellular matrix. In some vascular segments the intima was densely fibrotic and hyalinized. No significant inflammation, foam cells, cholesterol clefts, or other evidence of atheroma were present. T…
Sudden cardiac death while wearing a Holter monitor
1991
The Holter tapes of 61 patients (46 men, mean age +/- standard deviation 65 +/- 11 years) with sudden cardiac death while being monitored were analyzed. Thirty-eight patients were known to have coronary artery disease, 5 had cardiomyopathy, and 7 had aortic valve disease. Etiology remained unknown in 11 patients. Mean New York Heart Association functional class was 2.5 +/- 0.7. Thirty patients had received antiarrhythmic drugs and 32 had received digitalis. Sudden death occurred at rest in 73%. In the hours before death, repetitive ventricular arrhythmias were found in 50 patients (82%), with atrial fibrillation in 34%. Patients with bradyarrhythmic death (18%) had less complex ventricular …
Mortality after cardioverter-defibrillator replacement: Results of the DECODE survival score index
2020
Background Device replacement is the ideal time to reassess health care goals regarding continuing implantable cardioverter-defibrillator (ICD) therapy. Only few data are available on the decision making at this time. Objectives The goals of this study were to identify factors associated with poor prognosis at the time of ICD replacement and to develop a prognostic index able to stratify those patients at risk of dying early. Methods DEtect long-term COmplications after implantable cardioverter-DEfibrillator replacement (DECODE) was a prospective, single-arm, multicenter cohort study aimed at estimating long-term complications in a large population of patients who underwent ICD/cardiac resy…
Prognostic Role of Late Gadolinium Enhancement in Patients With Hypertrophic Cardiomyopathy and Low-to-Intermediate Sudden Cardiac Death Risk Score
2019
Sudden cardiac death (SCD) is the most life-threating complication of hypertrophic cardiomyopathy. Guidelines of the European Society of Cardiology (ESC) suggest the implantation of an implantable cardioverter defibrillator in primary prevention according to a 5-year risk SCD score >= 6%. The aim of the study is to evaluate the prognostic role of late gadolinium enhancement (LGE) in patients with a 5-year risk SCD score <6%. In this multicenter study, we performed cardiac magnetic resonance in 354 consecutive hypertrophic cardiomy-opathy patients (257 males, range of age 54 +/- 17) with a risk SCD score <6% (302 with <4% and 52 with >= 4 and <6% risk). Hard cardiac events,…
Mang Ke, Genzi e Duo Duo: i "tre moschettieri" del rinnovamento della poesia cinese contemporanea.
2004
Verso la fine degli anni Sessanta del secolo scorso, Mang Ke, Genzi e Duo Duo erano giovani studenti. Durante la Rivoluzione Culturale, insieme a un gran numero di giovani, furono inviati nelle zone rurali per conoscere le condizioni di vita di un popolo cinese che doveva essere incoraggiato alla costruzione di uno stile di vita comunista. L'esperienza nelle aree rurali trasformerà Mang Ke, Genzi e Duo Duo in poeti. Già noti mentre erano a Baiyangdian come i "tre moschettieri" per via della loro amicizia, avvieranno un processo di rinnovamento della poesia cinese contemporanea.

Noncompaction of the Right Ventricle
2010
Noncompaction of the ventricular myocardium is a disease characterized by an increase of the ventricular trabecular meshwork caused by arrest of the normal endomyocardial morphogenesis (Figs. 1, 2, 3). In accordance with the normal human anatomy, the left ventricular wall is well compacted with a few thin trabeculae; on the contrary, the normal right ventricular wall is furrowed by many trabeculae (the trabecula of the marginal septum as well as other ones). For this reason, the term ‘‘noncompaction’’ usually refers to an exclusive or prevalent disease of the left ventricle [1–16]. Recently Song and Aragona et al. [1–3] reported two cases of isolated right-ventricular noncompaction. Accordi…
A new intermediate intercalate in superconducting sodium-doped hafnium nitride chloride
2005
Anew phase has been observed during the sodiumintercalation of hafnium nitride chloride as intermediate between the host β-HfNCl and the already reported Na 0.29 HfNCl with Tc of 24 K; the new intermediate shows interlayer spacings ranging from 9.48 to 9.67 A°, corresponds to a second stage intercalate of HfNCl and is superconducting with a critical temperature of 20 K.
