Abstract:

This project aims to investigate cardiac function in patients with cirrhosis in the acute setting. Acute decompensation and acute-on-chronic liver failure are major events in the life of a patient as they herald disease progression and negative prognosis. Although systemic inflammation and organ failure are essential to understanding the evolution of the disease, so far there have been no investigations into the role cardiac function plays in this setting. This project will investigate the dynamic changes in cardiac function through echocardiography, electrocardiography, serum markers of inflammation (leukocytes, C-reactive protein, interleukin-6 and 8, soluble mannose receptor) and cardiac injury (troponin T, pro-brain natriuretic peptide) at different time-points (enrollment, 5-7 days after admission, 30 and 90 days) in a prospective, cohort, follow-up study of patients with cirrhosis admitted for acute decompensation. An analysis of variables derived from echocardiographic, biological and clinical data will be performed in order to identify significant associations between parameters of cardiac function, markers of inflammation, and severity of liver disease as assessed by specific scores (CLIF-C). We expect to show that cardiac function is related to inflammation and that it plays an independent, significant role in the development of organ failure and negative outcome (repeated decompensation, hospitalization, worsening of disease or death during follow-up).

Abstract:

Hypertrophic cardiomyopathy (HCM), the most common inherited cardiomyopathy, is a challenging disease, often having an unpredictable clinical course. Atrial and ventricular arrhythmias contribute directly to the mortality and morbidity of HCM patients (pts). Because current risk stratification strategies for prevention of sudden death are imperfect, the identification of new parameters able to better reveal the arrhythmogenic substrate and risk of arrhythmias is of interest. The main objective of our study is to find new parameters to identify HCM pts at risk for arrhythmias - ventricular arrhythmias (VA), atrial fibrillation (AF). We will use an approach based on advanced imaging assessment of cardiac mechanics and dynamic left ventricular outflow tract obstruction, both at rest and during exercise. We aim to develop a machine-learning (ML) model able to improve the identification of high-risk cardiac phenotypes on speckle echocardiography data, using as ground truth information extracted from cardiac magnetic resonance (CMR). We intend to demonstrate that ML models, generated by the integration of clinical, ECG, CMR, rest and exercise echocardiographic data, have better ability in detecting and predicting arrhythmias compared to conventional methods. An integrative approach for arrhythmic risk stratification provided by imaging and artificial intelligence may become a decision-making tool able to reduce the VA- and AF-related morbidity and mortality in pts with HCM.

CONFIRMATION OF A PANEL OF NOVEL CANDIDATE PROTEOMIC BIOMARKERS IN SYSTEMIC SCLEROSIS PATIENTS Call name: P 1 - SP 1.1 - Proiecte de cercetare Postdoctorală

Abstract:

Rationale: Systemic sclerosis (Ssc) is an autoimmune disease with incompletely known physiopathology being a challenge for both clinicians and researchers. Research efforts are focusing upon identifying novel and relevant biomarkers that have good predictive values for prognosis, stratification and monitoring therapeutic response of Ssc patients. Studies using high throughput genomic/proteomic platforms have identified numerous candidate biomarkers for Ssc. Nevertheless, independent studies and confirmation of all these candidate biomarkers are needed to be conducted in the clinical setting in order to translate the tremendous information gathered into clinical practice.

Aims: The aim of the project is confirmation of novel promising proteomic biomarkers identified using mass-spectrometry studies already performed on Ssc patients. The outcome of the project will be a panel of promising, confirmed biomarkers associated with clinical characteristics of Ssc that will be useful for clinical practice after validation on Ssc cohort studies.

Foreseen impact: The project has an important impact in translating basic knowledge of Ssc biomarkers into clinical use by conducting a confirmation and validation study of promising biomarkers in a specific clinical setting. It is an important intermediate but mandatory step. The project proposal is in line with the international quest for reliable blood biomarkers for disease/therapy monitoring in Ssc patients, pinpointing and confirming proteomic signature from candidate biomarkers identified with mass spectrometry studies. The project will be able to transform basic research results into clinical practice.

Methodology: In order to confirm selected biomarkers (members of chaperon group of proteins but also other promising candidates) a case control study is envisaged. Patients with Ssc will be selected and samples and data from the available biobank will be included in analysis. The project is divided into 4 specific Work packages.

Abstract:

Calcific aortic stenosis (AS) is the most common valvular heart disease, with an increasing prevalence due to the ageing population. Management of asymptomatic patients (pts) with severe AS is still under debate due to difficulties in accurately balancing the risk of intervention versus that of watchful waiting. Based on pathophysiological data we hypothesised that a comprehensive assessment of arterial stiffness, left ventricular (LV) and left atrial (LA) function at rest and during exercise could identify markers of increased risk in asymptomatic severe AS.

Using exercise echocardiography, we aim to assess for the first time the predictive value of exercise-induced response of parameters of LV systolic and diastolic function (LV myocardial deformation parameters, LV untwisting, E/E’ ratio, BNP serum level) and LA functional reserve in asymptomatic pts with severe AS. We also intend to perform a comparative assessment of vascular and cardiac function in asymptomatic versus symptomatic pts with severe AS and preserved LV ejection fraction and to assess the impact of aortic valve replacement on different parameters of cardiac function in symptomatic pts with severe AS evaluated at rest by state-of-the-art imaging techniques (carotid e-tracking, tissue Doppler/speckle tracking echocardiography, 3D-echocardiography). Incorporating these new parameters into a risk score for outcome prediction in asymptomatic severe AS may provide an useful tool for clinical decision making.
