Respiratory Syncytial Virus (RSV) and Intention to Recommend RSV Vaccination: A Cross-Sectional Survey of Cardiologists and Cardiac Nurses in Southern Italy.

As respiratory syncytial virus (RSV) vaccine distribution gains traction in Europe and Italy, healthcare workers (HCWs) can strategize about vaccine promotion to increase uptake among patients at risk of RSV consequences, such cardiac patients. This cross-sectional survey investigated the knowledge about and attitude towards RSV and RSV vaccines, and the intention to recommend vaccination within a cardiological hospital in Italy. To explore factors associated with the outcomes of interest, multivariate logistic regression analyses were conducted.

Knowledge, Attitudes and Practices Survey of Recombinant Zoster Vaccine among Cardiologists and Cardiac Nurses in Italy.

: Cardiac patients are particularly at risk of herpes zoster (HZ), which is associated with a higher risk of major cardiovascular events. This research aimed to analyze the knowledge, attitudes and practices towards recombinant zoster vaccine (RZV) among cardiac healthcare professionals (HPs). : A cross-sectional survey was conducted in a cardiological hospital in Italy.

Efficacy of the New Inotropic Agent Istaroxime in Acute Heart Failure.

Current therapeutic strategies for acute heart failure (AHF) are based on traditional inotropic agents that are often associated with untoward effects; therefore, finding new effective approaches with a safer profile is dramatically needed. Istaroxime is a novel compound, chemically unrelated to cardiac glycosides, that is currently being studied for the treatment of AHF. Its effects are essentially related to its inotropic and lusitropic positive properties exerted through a dual mechanism of action: activation of the sarcoplasmic reticulum Ca ATPase isoform 2a (SERCA2a) and inhibition of the Na/K-ATPase (NKA) activity.

Role of Intracardiac echocardiography in Atrial Fibrillation Ablation.

In the recent years, several new evidences support catheter-based ablation as a treatment modality of atrial fibrillation (AF). Based on a plenty of different applications, intracardiac echocardiography (ICE) is now a well-established technology in complex electrophysiological procedures, in particular in AF ablation. ICE contributes to improve the efficacy and safety of such procedures defining the anatomical structures involved in ablation procedures and monitoring in real time possible complications.

Prognostic value of extravascular lung water assessed with ultrasound lung comets by chest sonography in patients with dyspnea and/or chest pain.

Background: Ultrasound lung comets (ULCs) consist of multiple comet tails originating from water-thickened interlobular septa. They are a new echographic tool to assess the pathologic increase in extravascular lung water, which is a possible harbinger of impending acute heart failure. The objective was to assess the prognostic value of ULCs in patients with dyspnea and/or chest pain syndrome at hospital admission.

Clinical and echocardiographic determinants of ultrasound lung comets.

Background: Ultrasound lung comets (ULCs) are an echographic sign of extravascular lung water, that originate from water-thickened interlobular septa.

Aim: To establish the echocardiographic correlates of ULCs.

Methods: 340 in-hospital patients (68 +/- 12years, 115 females) admitted to adult cardiology department underwent upon admission a separate evaluation of chest ULCs and a comprehensive 2D and Doppler echocardiography assessment, including the degree of left ventricular diastolic dysfunction (from 0 = normal to 3 = restrictive pattern).

Cardiac catheterization and long-term chromosomal damage in children with congenital heart disease.

Aims: Medical radiological exposure is associated with an additional risk of cancer. Children with repaired congenital heart disease (CHD) are theoretically at a relatively greater cancer risk as the radiological exposure can be intensive in these patients. Chromosomal aberrations test (CA) and micronucleus assay (MN) in peripheral blood lymphocytes are biomarkers of chromosomal damage and intermediate endpoints in carcinogenesis.

Ultrasound lung comets: a clinically useful sign of extravascular lung water.

Assessment of extravascular lung water is a challenging task for the clinical cardiologist and an elusive target for the echocardiographer. Today chest x-ray is considered the best way to assess extravascular lung water objectively, but this requires radiology facilities and specific reading expertise, uses ionizing energy, and poses a significant logistic burden. Recently, a new method was developed using echocardiography (with cardiac probes) of the lung.

Noninvasive assessment of left ventricular contractility by pacemaker stress echocardiography.

Background: Estimating contractility of the left ventricle with noninvasive techniques is an important yet elusive goal. Positive inotropic interventions are mirrored by smaller end-systolic volumes and higher end-systolic pressures. An increased heart rate progressively increases the force of ventricular contraction (Bowditch treppe or staircase phenomenon).

Usefulness of ultrasound lung comets as a nonradiologic sign of extravascular lung water.

The "comet-tail" is an ultrasound sign detectable with ultrasound chest instruments; this sign consists of multiple comet-tails fanning out from the lung surface. They originate from water-thickened interlobular septa and would be ideal for nonradiologic bedside assessment of extravascular lung water. To assess the feasibility and value of ultrasonic comet signs, we studied 121 consecutive hospitalized patients (43 women and 78 men; aged 67 +/- 12 years) admitted to our combined cardiology-pneumology department (including cardiac intensive care unit); the study was conducted with commercially available echocardiographic systems including a portable unit.
