Sildenafil improves clinical and functional status of an elderly postmenopausal female with ‘out of proportion’ PH associated with left heart disease

We report a case of an elderly woman with heart failure with preserved ejection fraction and pulmonary hypertension (HFpEF-PH), refractory to conventional therapy for left heart failure and successfully treated by sildenafil

Prognostic role of neoplastic markers in Takotsubo syndrome

Takotsubo syndrome (TTS) is an acute heart failure syndrome with significant rates of in and out-of-hospital mayor cardiac adverse events (MACE). To evaluate the possible role of neoplastic biomarkers [CA-15.3, CA-19.9 and Carcinoembryonic Antigen (CEA)] as prognostic marker at short- and long-term follow-up in subjects with TTS. Ninety consecutive subjects with TTS were enrolled and followed for a median of 3 years. Circulating levels of CA-15.3, CA-19.9 and CEA were evaluated at admission, after 72 h and at discharge. Incidence of MACE during hospitalization and follow-up were recorded. Forty-three (46%) patients experienced MACE during hospitalization. These patients had increased admission levels of CEA (4.3 ± 6.2 vs. 2.2 ± 1.5 ng/mL, p = 0.03). CEA levels were higher in subjects with in-hospital MACE. At long term follow-up, CEA and CA-19.9 levels were associated with increased risk of death (log rank p < 0.01, HR = 5.3, 95% CI 1.9-14.8, HR = 7.8 95% CI 2.4-25.1, respectively, p < 0.01). At multivariable analysis levels higher than median of CEA, CA-19.9 or both were independent predictors of death at long term (Log-Rank p < 0.01). Having both CEA and CA-19.9 levels above median (> 2 ng/mL, > 8 UI/mL respectively) was associated with an increased risk of mortality of 11.8 (95% CI 2.6-52.5, p = 0.001) at follow up. Increased CEA and CA-19.9 serum levels are associated with higher risk of death at long-term follow up in patients with TTS. CEA serum levels are correlated with in-hospital MACE

Diagramma: uno strumento di rivoluzione metodologica

Il volume è la raccolta degli Atti del Simposio “Big Ben. Il lavoro di UNStudio”, tenutosi a Roma il 4 Maggio 2014 presso il MAXXI Museo nazionale delle Arti del XXI secolo. Il volume condivide la medesima struttura del Simposio, articolandosi intorno a cinque blocchi tematici individuati da altrettante parole chiave: diagramma, struttura, modello, pelle e ibridazione. Le sezioni introduttive riferite a ciascun argomento sono a firma di autori di volumi monografici su UNStudio mentre gli scritti che sviluppano i singoli temi sono redatti dagli architetti del corso di Dottorato di ricerca

Progetto The Walking Factory - Ri(m)argina

Il progetto dà forma architettonica ad un impianto di stoccaggio e riciclo degli scarti prodotti dai processi di Costruzione e Demolizione. L'edificio, concepito secondo criteri di prefabbricazione, si innesta su un argine artificiale connesso ad un nuovo parco fluviale, ed accoglie oltre all'impianto c&d anche aree di divulgazione, didattiche e di ricerca sui temi del riciclo

Dynamic changes of QTc interval and prognostic significance in takotsubo (stress) cardiomyopathy

Background: Prolonged QT corrected (QTc) intervals are associated with adverse cardiovascular outcomes both in healthy and high-risk populations. Our objective was to evaluate the QTc intervals during a takotsubo cardiomyopathy (TTC) episodes and their potential prognostic role. Hypothesis: Dynamic changes of QTc interval during hospitalization for TTC could be associated with outcome at follow-up. Methods: Fifty-two consecutive patients hospitalized for TTC were enrolled. Twelve-lead electrocardiogram (ECG) was performed within 3 h after admission and repeated after 3, 5, and 7 days. Patients were classified in 2 groups: group 1 presented the maximal QTc interval length at admission and group 2 developed maximal QTc interval length after admission. Results: Mean admission QTc interval was 493 ± 71 ms and mean QTc peak interval was 550 ± 76 ms (P < 0.001). Seventeen (33%) patients were included in group 1 and 35 (67%) patients in group 2. There were no differences for cardiovascular risk factors and in terms of ECG findings such as ST elevation, ST depression, and inverted T waves. Rates of adverse events during hospitalization among patients of group 1 and 2 were different although not significantly (20% vs 6%, P = 0.22). After 647 days follow-up, patients of group 1 presented higher risk of cardiovascular rehospitalization (31% vs 6%, P = 0.013; log-rank, P < 0.01). At multivariate analysis, including age and gender, a prolonged QTc interval at admission was significantly associated with higher risk of rehospitalization at follow-up (hazard ratio: 1.07 every 10 ms, 95% confidence interval: 1.003-1.14, P = 0.04). Conclusions: Prolonged QTc intervals at admission during a TTC episode could be associated with a higher risk of cardiovascular rehospitalization at follow-up. Dynamic increase of QTc intervals after admission are characterized by a trend toward a better prognosis
