METODI DI STUDIO DELLA VARIABILITA’ DELLA FREQUENZA CARDIACA
2010
La frequenza cardiaca (FC) è controllata dal sistema nervoso vegetativo. Il nodo senoatriale (SA) ha una frequenza propria di depolarizzazione spontanea conosciuta come “frequenza intrinseca” che rappresenta la frequenza misurata in assenza di impulsi simpatici o parasimpatici come si può ottenere con la denervazione o il blocco farmacologico. Nei soggetti normali la frequenza intrinseca è di circa 100 bpm e dipende dal sesso e dall’età ed è influenzata dall’esercizio fisico, l’ipossia e le variazioni di temperatura. I soggetti allenati a sport di resistenza hanno una frequenza intrinseca minore. Gli effetti del sistema simpatico e parasimpatico influenzano in maniera predominante la FC int…

Pentamidine rescues contractility and rhythmicity in a Drosophila model of myotonic dystrophy heart dysfunction
2015
Up to 80% of individuals with myotonic dystrophy type 1 (DM1) will develop cardiac abnormalities at some point during the progression of their disease, the most common of which is heart blockage of varying degrees. Such blockage is characterized by conduction defects and supraventricular and ventricular tachycardia, and carries a high risk of sudden cardiac death. Despite its importance, very few animal model studies have focused on the heart dysfunction in DM1. Here, we describe the characterization of the heart phenotype in a Drosophila model expressing pure expanded CUG repeats under the control of the cardiomyocyte-specific driver GMH5-Gal4. Morphologically, expression of 250 CUG repeat…
Obesity and cardiovascular risk: a call for action from the European Society of Hypertension Working Group of Obesity, Diabetes and the High-risk Pat…
2018
: Obesity predisposes for atrial fibrillation, heart failure, sudden cardiac death, renal disease and ischemic stroke, which are the main causes of cardiovascular hospitalization and mortality. As obesity and the cardiovascular effects on the vessels and the heart start early in life, even from childhood, it is important for health policies to prevent obesity very early before the disease manifestation emerge. Key roles in the prevention are strategies to increase physical exercise, reduce body weight and to prevent or treat hypertension, lipids disorders and diabetes earlier and efficiently to prevent cardiovascular complications.

Can The Aortic Wall Comunicate With Us?
2014
OBJECTIVE: Association between aortic aneurysm wall and risk of rupture or dissection. METHODS: Aortic specimens were obtained from 73 patients (51 men and 22 women, whose median age 61.7± 10.7 years) undergoing surgical repair of thoracic ascending aneurysm (TAA). Histopathological and immunohistochemical analyses were performed using adequate tissue specimens, appropriate techniques and criteria. Furthermore, genetic risk factors were also investigated. RESULTS: We identified three phenotypes of TAAs with different quality of aortic wall at the time of operation: phenotype I (normal wall); phenotype II (moderate wall thickness); phenotype III (thin and weak wall). No significant differenc…
Alteraciones en la producción y secreción de los péptidos natriuréticos y sus moléculas relacionadas en pacientes con insuficiencia cardiaca. Relació…
2016
La insuficiencia cardiaca es un síndrome multifactorial de gran impacto en la asistencia sanitaria debido al aumento de la morbilidad y la mortalidad y la ausencia de un tratamiento curativo. Es el resultado, no solo de una sobrecarga o daño cardiaco, sino también de una compleja interacción de cambios genéticos, neurohormonales, inflamatorios y bioquímicos que actúan sobre el miocito y/o el intersticio. Como consecuencia de estas alteraciones, el paciente con insuficiencia cardiaca tiene niveles anómalos de diversas moléculas (enzimas, hormonas, citocinas…) que son utilizadas como biomarcadores de gran importancia clínica. En este sentido, el papel de los péptidos natriuréticos en la clíni…
Echocardiographic Evaluation of the Cardiac Chambers in Asthmatic Patients: The BADA (Blood Pressure Levels, Clinical Features and Markers of Subclin…
2022
The “Blood pressure levels, clinical features and markers of subclinical cardiovascular Damage of Asthma patients” (BADA) study is aimed at defining the cardiovascular risk profile and the markers of subclinical and clinical vascular and cardiac damage in asthmatic patients. Very few studies have assessed asthmatic patients without concomitant heart disease through a transthoracic echocardiogram. The goal of the present study is to investigate the prevalence of morphology and/or function changes in the cardiac chambers of a sample of 86 patients with chronic asthma, referred to the dedicated outpatient unit of the Division of Respiratory Diseases of the AOUP “P. Giaccone&r…
