Right Heart and Lung Blood Flow During Exercise (RIGHT-NET 2.0) (RIGHT-NET 2)

25 września 2026 zaktualizowane przez: Marco Salvatore, IRCCS SYNLAB SDN

The Right Heart International NETwork 2.0 (RIGHT-NET 2.0)

RIGHT-NET 2.0 is a multicenter observational study with a retrospective-prospective design that builds on the original RIGHT-NET study. It aims to observe and document the functional status of the right heart-pulmonary circulation unit (RH-PCU) at rest and during exercise stress transthoracic echocardiography (ExTTE) in clinically stable patients referred to cardiology, internal medicine, echocardiography, and exercise testing laboratories. The study will also include healthy volunteers, individuals with cardiovascular risk factors but no overt disease, athletes undergoing sports eligibility evaluation, and healthy individuals living at high altitude. Patients will be classified according to the 2022 ESC/ERS Guidelines for the diagnosis and treatment of pulmonary hypertension. The study plans to enroll at least 1000 additional subjects beyond the original RIGHT-NET cohort of 1000 participants, for a total anticipated enrollment of approximately 2000 subjects across 22 Italian and 16 international centers. Data will be collected through the REDCap electronic data capture platform in a pseudonymized format.

Szczegółowy opis

The clinical and instrumental assessment of the right heart-pulmonary circulation unit is an essential step in the diagnostic, prognostic, and therapeutic algorithm of cardiorespiratory diseases. The original RIGHT-NET study demonstrated the relevance of physiological versus pathological responses through evaluation of the TAPSE/sPAP ratio and mPAP/CO slope during exercise stress echocardiography, both of which carry prognostic significance and predict all-cause mortality across healthy subjects, athletes, high-altitude residents, and patients with cardiopulmonary disease.

Study objectives include advancing understanding of RH-PCU physiology and pathophysiology during exercise, assessing the discriminative capacity of TAPSE/sPAP and mPAP/CO slope across clinical conditions, investigating associations between RH-PCU functional indices and short-, medium-, and long-term clinical outcomes including all-cause mortality, refining diagnostic and prognostic thresholds in line with the 2022 ESC/ERS guidelines, and building a standardized dataset via REDCap.

For each participant, demographic, anthropometric, and clinical characteristics will be collected, together with laboratory tests, invasive and non-invasive diagnostic procedures (including right heart catheterization, cardiac MRI, nuclear diagnostics, and arterial blood gas analysis), therapy data, and clinical outcomes. Data will be analyzed using R (version >= 4.3.1) with descriptive statistics, group comparisons, univariate and multivariate regression models, and supervised machine learning techniques (random forest, gradient boosting, support vector machine) for predictive modeling.

As an observational study, participation does not alter the participant's diagnostic or therapeutic pathway, and no additional insurance coverage beyond standard clinical practice is required.

Badana populacja

Patients referred, as part of their routine clinical pathway, to cardiology, internal medicine, echocardiography, or exercise testing (ergometry) laboratories at the participating centers, selected based on a documented clinical indication for right heart-pulmonary circulation unit assessment as determined by the referring physician, and classified according to the 2022 ESC/ERS Guidelines for the diagnosis and treatment of pulmonary hypertension. The population also includes healthy volunteers, including individuals undergoing occupational fitness assessment; individuals with cardiovascular risk factors but no overt cardiopulmonary disease; athletes referred for sports eligibility evaluation; and healthy individuals living at high altitude.

Patients with Clinical Indication for RH-PCU Assessment

Patients referred, as part of their routine clinical pathway, to cardiology, internal medicine, echocardiography, or exercise testing laboratories for evaluation of right heart-pulmonary circulation unit function, based on a documented clinical indication as determined by the referring physician. Patients are classified according to the 2022 ESC/ERS Guidelines for the diagnosis and treatment of pulmonary hypertension. Intervention/exposure of interest: rest and exercise stress transthoracic color-Doppler echocardiography (ExTTE); additional non-invasive and invasive diagnostic procedures (right heart catheterization, cardiac MRI, nuclear diagnostics, arterial blood gas analysis) are performed where clinically indicated, as part of standard care.

Healthy Volunteers

Healthy individuals enrolled as volunteers or referred for assessment of fitness for work, with no known cardiopulmonary disease. Intervention/exposure of interest: rest and exercise stress transthoracic echocardiography (ExTTE), performed as part of the study assessment.

Subjects with Cardiovascular Risk Factors

Individuals presenting cardiovascular risk factors (e.g. hypertension, dyslipidemia, obesity, diabetes) but without overt cardiovascular or respiratory disease. Intervention/exposure of interest: rest and exercise stress transthoracic echocardiography (ExTTE), performed as part of the study assessment.

Athletes Undergoing Sports Eligibility Evaluation

Athletes referred to participating centers for evaluation of fitness for competitive or amateur sports activity. Intervention/exposure of interest: rest and exercise stress transthoracic echocardiography (ExTTE), performed as part of the study assessment.

Healthy Subjects Living at High Altitude

Healthy individuals residing at high altitude, included to characterize right heart-pulmonary circulation unit adaptation to chronic hypoxic exposure. Intervention/exposure of interest: rest and exercise stress transthoracic echocardiography (ExTTE), performed as part of the study assessment.
