Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
SE2030 will establish the platform of evidence to build the perfect SE test, suitable for all patients, anywhere, anytime, also quantitative and operator independent. The need for such an ideal test is especially vital in our times, when the economic crisis, the increased awareness of cancer and non-cancer radiation damage, the pressing need for climate-neutral choices in health care, and the unavoidable trend to externalize health care are potent propelling forces, boosted by COVID pandemics, for the diffusion of a low cost, radiation-free, climate-friendly, and portable technique such as cardiovascular ultrasound.
Methodology. Five important aspects will be shared by SE2030 in full continuity with SE2020, with minor adaptations and implementations.
Upstream quality control. The study is a prospective registry but it is necessary to have an upstream quality control with a certified reader from each center. A mandatory quality control is necessary for conventional and innovative parameters, since the volume of activity is necessary but not sufficient to ensure the quality of reading.
Peripheral reading and inclusivity. Once the reader has been certified, the peripheral reading will be directly entered in the data bank via the Redcap program property of the Italian Society of Echocardiography and Cardiovascular Imaging. This will allow a more flexible and rapid platform, less error in data inputting and better compliance with new regulations strictly protecting privacy in clinical studies. Another feature of SE2030 is inclusivity, so that any center meeting the selection criteria can be enrolled, allowing centers traditionally outside the editorial stage but producing high quality clinical activity to contribute to generate data relevant for the scientific community.
Uniform methodology. Each laboratory will adopt the preferred choice of stress among physical, pharmacologic or pacing stress according to standardized protocol in line with guidelines recommendations. Physical exercise includes semi-supine or upright bicycle exercise, and peak or post-treadmill exercise. Pharmacologic testing will be with dobutamine or vasodilators (dipyridamole, adenosine or regadenoson) according to physician preferences, patients' contraindications, local availability and cost. Pacing stress can be performed with transesophageal atrial pacing or with external programming of a permanent pacemaker. Independent of the chosen form of stress, execution, performance, archiving and interpretation of testing will follow a standardized format with the ABCDE protocol. From the technical viewpoint of success rate, a limiting step is step D. Step D is easy and feasible with vasodilator, less easy but still highly feasible with dobutamine, not easy and less feasible with semi-supine exercise, and virtually impossible with (peak or post) treadmill exercise. Therefore, our recommendation is to use semi-supine exercise, capturing coronary flow signal in early or intermediate stages of exercise when most flow increase occurs and feasibility is still high, before it drops at higher levels of exercise. When treadmill is used, step D is skipped; if information is deemed important, a vasodilator test can be performed at 30' after the end of exercise focused on CFVR and heart rate response.
All laboratories will be granted with free artificial intelligence (AI) software and encouraged to use ultrasound enhancing agents when needed to help leading edge technology upgrade and uniformity of methods across all study laboratories .
The full spectrum of enrolled patients evaluated for clinically relevant endpoints. The various projects will include patients with known or suspected CAD (project 1), known or suspected heart failure with preserved ejection fraction (project 2), hypertrophic cardiomyopathy (HCM, project 3), status post-chest radiotherapy and chemotherapy (project 4), repaired Tetralogy of Fallot (project 7), cardio-pulmonary involvement post-COVID 19 (project 8), post-ischemic (project 10) and primary valvular heart disease (project 11) and suspected coronary vasospasm, a diagnosis frequently missed but important to recognize as a possible cause of life-threatening disease, which is easy to treat when promptly identified (project 12). The 12 protocols running on the SE-ABCDE platform are spread all over the spectrum of cardiovascular disease, from severe valvular heart disease to suspected CAD in patients with normal LV function. Potential heart donors with brain death will be evaluated to assess the suitability for donation of hearts currently dismissed on the basis of clinical history criteria but in the absence of a cardiac functional evaluation (project 9). The study will exploit and possibly contribute to upgrade the leading edge quantitative and operator-independent technology of AI-SE and cardiac strain (project 5) for image interpretation and data analysis and will also evaluate the results of SE parameters in the context of powerful environmental modulators of stress results and/or long-term outcome such as air pollutants and medical radiation exposure analyzed through big data mining with AI (project 6). The overarching aim of the study is to make SE practice more uniform, versatile, standardized, quantitative and evidence-rich, producing data potentially relevant to change clinical practice.
Sponsored by a professional scientific society. The study is investigator-driven and not industry-driven. It is endorsed by an independent-not for profit professional society (Italian Society of Echocardiography and Cardiovascular Imaging) and not sponsored by industry, although some materials useful for project completion such as AI-software will be donated by industrial partners for recruiting centers.

ABCDE-Stress Echo in Coronary Artery Disease (SECAD project)
All patients with known or suspected CAD will be evaluated with ABCDE-SE. Patients will be referred according to existing 2020 guidelines indication; status post heart transplant; pediatric patients and congenital heart disease ; peri-partum cardiomyopathy.

All patients will enter a regular clinical follow-up program with annotation of cardiovascular and non-cardiovascular endpoints, such as cancer or neurodegenerative disease, characterized by endothelial dysfunction (step D positivity) and autonomic dysfunction (step E positivity). A sample size of about 2 430 patients with a 5-year follow-up is required to provide 90% power with an alpha error of 5% to detect a difference for the primary endpoint of all-cause mortality among those with positive versus negative SE also considering a 20% drop-out.

ABCDE-Stress Echo post-Radiotherapy (SERA project)
Radiation-induced heart disease is associated with a significantly higher morbidity and mortality in cancer patients. The most frequent forms treated with chest radiation therapy are breast, lung, and esophageal cancers or lymphoma. The chances of developing radiation-induced heart disease increase with higher cumulative doses (\>30 Gray) in anterior or left sided irradiation, concomitant chemotherapy, presence of cardiovascular risk factors, and increased distance from time of irradiation. The estimated incidence of major cardiac events related to ischemic heart disease is 30% at 10 years post-treatment in female patients with radiotherapy post-breast cancer. The resulting epicardial artery stenosis, low grade inflammation , myocardial fibrosis, microvascular injury , alterations in autonomic balance, valve leaflets, and accelerated calcification can lead to significant alteration of all SE steps. A sample size of 507 patients is required and will be enrolled.

ABCDE- Artificial Intelligence Stress echo (AI-SEE)
The project have 2 separate aims: AI-SEE images: To make SE reading operator-independent for each of the essential reading steps (from A to E). AI-SEE data: To identify the links between clinical imaging and stress variables and develop a tailored personalized model for risk prediction. For each parameter assessment (positivity versus negativity), the area under the receiver-operating characteristic curve produced by the deep learning algorithm will be compared to that produced by the experienced cardiologist (cross-sectional analysis). AI-SEE images: a set of images from 1 250 patients from at least 10 laboratories will be sufficient to develop the algorithm (modeling set) subsequently prospectively tested on a different set of 1250 patients (validation set). AI-SEE data: a set of data from 2 500 patients from at least 10 laboratories will be sufficient to develop the algorithm (modeling set) subsequently tested on a different set of 2 500 patients (validation set).

RESURGE: Recovery by stress echo of conventionally unfit donor good hearts.
The primary aim is to recruit hearts from donation which are currently excluded by conventional criteria as aged hearts in patients \> 55 years and ≤ 55 years with multiple risk factors. Secondary aim is to assess outcome in SE-driven transplantation compared to hearts transplanted in the same cardiac surgery centers on the basis of conventional criteria. Tertiary aim is to assess the additional prognostic value of other signs not used for decision-making. These aspects may include diastolic function, preload reserve, coronary microvascular function, and residual innervation of the intrinsic cardiac autonomic system through assessment of HRR in donor heart. In case of donor with age \>55 years o ≤ 55 years but with concomitant ≥ 3 risk factors (diabetes, hypertension, smoking, obesity, hypercholesterolemia) or history of cardiac arrest, the protocol will be applied.
ABCDE-Stress Echo
Each laboratory will adopt the preferred Echo stress among physical pharmacologic or pacing stress according to guidelines recommendations. Pharmacologic testing will be with dobutamine or vasodilators (dipyridamole, adenosine or regadenoson) according to physician preferences, patients' contraindications, local availability and cost.

When treadmill is used, step D is skipped; if information is deemed important, a vasodilator test can be performed at 30' after the end of exercise focused on CFVR and heart rate response.
SE in heart donors
The examination of the heart starts with a resting transthoracic echocardiography. Exclusion criteria are: resting wall motion score index\>1.0; ejection fraction \<45%; diastolic dysfunction of grade 2 or more; hemodynamically significant (moderate or higher) valve regurgitation or stenosis; severe left ventricular hypertrophy (left ventricular mass index \>175 g/m2). A pharmacological SE with dipyridamole (0.84 mg/kg over 6 minutes) is recommended. The diagnostic end-points are stress-induced RWMA and abnormalities in global LVCR. All images will be analyzed as per guidelines similarly to the other projects, with emphasis on wall motion score index and LVCR based on ejection fraction and force. The hearts excluded from donation for RWMA or abnormal LVCR could however be collected for heart valve preparation and evaluated by coronary angiography and by pathological examination according to local facilities.
SEMIR- Stress echo in ischemic mitral regurgitation
The value of SE testing as an indicator of outcome will be assessed in patients with resting moderate mitral regurgitation (effective regurgitant orifice 0.2-0.39 cm2, and regurgitant volume 30-59 ml) of ischemic origin and angiographically documented CAD, and will enter a regular clinical follow-up program with annotation of cardiovascular and non-cardiovascular endpoints. Patients undergoing CABG with or without mitral repair or PCI with or without mitral valve intervention will be separately analyzed. A sample size of 173 patients per arm (CABG or PCI) is required. The primary hypothesis is that patients with moderate mitral regurgitation worsening of ≥ 1 grade during exercise have worse outcome on medical therapy and greater benefit from valve correction. The secondary hypothesis is that patients with worse SE pre-surgery parameters will have worse prognosis independent of regurgitation severity and treatment (medical therapy or valve repair).

Peak systolic tricuspid annulus velocity and conventional indices of left ventricular systolic and diastolic function will also be measured at baseline and peak stress according to the standard ABCDE-FGLPR protocol. Right ventricular free wall strain combined with interventricular septum strain will be assessed. Left ventricular function, wall motion score index and E/e' at baseline and peak stress.
SEVA: Stress Echocardiography in Valvular Heart Disease
SE is recommended in valvular heart disease in patients characterized by a mismatch between resting transthoracic echocardiography findings and symptoms during exercise or activities of daily living: 1. Severe valve disease without symptoms; 2. Non-severe single- or multi-valve disease with symptoms; and 3. Symptomatic valve disease of indeterminate severity in context of low flow. The primary aim is to evaluate the feasibility of ABCDEFG-SE plus L (left atrium), P (pulmonary vascular reserve) and R (right ventricular function) in these patients. The secondary aim is to assess the correlation of each SE parameter with indices of functional severity (NYHA, cardiac natriuretic peptides, peak oxygen consumption, etc.). The tertiary aim is to assess the prognostic value of SE for prognostic stratification in the long-term. A sample size of about 217 patients per sub-group is required to evaluate the tertiary endpoint with 90% power and an alpha error of 5% .
ABCDE-Stress Echo
Each laboratory will adopt the preferred Echo stress among physical pharmacologic or pacing stress according to guidelines recommendations. Pharmacologic testing will be with dobutamine or vasodilators (dipyridamole, adenosine or regadenoson) according to physician preferences, patients' contraindications, local availability and cost. Pacing stress can be performed with transesophageal or with external permanent pacemaker. A standardized format with the ABCDE protocol will be followedl. Step D is easy with vasodilator, less easy with dobutamine, not easy and less feasible - impossible with (peak or post) treadmill exercise. Our recommendation is to use semi-supine exercise, capturing coronary flow signal in early or intermediate stages when most flow increases and feasibility is still high. When treadmill is used, step D is skipped; if information is deemed important, a vasodilator test can be performed at 30' after the end of exercise focused on CFVR and heart rate response.
SE diastolic assessment
The diastolic assessment should be included into all exercise SE tests by measuring standard Doppler-derived mitral inflow velocity, pulsed Tissue Doppler of mitral annulus, and retrograde tricuspid gradient of tricuspid regurgitation, at intermediate load of exercise and/or 1- 2 min after the end of the exercise. We will also assess, at baseline, intermediate load (50 watts) and peak-post stress: end-diastolic left ventricular volume index; end-systolic left ventricular volume index; ejection fraction and both stroke volume and cardiac output (to assess conventional contractile reserve); mitral regurgitation and left ventricular outflow tract obstruction; pulmonary artery systolic pressure; B-lines; right ventricular free wall strain to assess the presence of right ventricular dysfunction; left atrial volume index; peak atrial longitudinal strain; and mitral inflow E velocity and mitral annulus e' tissue Doppler velocity; global longitudinal strain (GLS).
SE Right ventricular function assessment
Right ventricular function will be assessed at baseline and peak stress with variations of tricuspid annular plane systolic excursion, an index of right ventricular longitudinal function, and right ventricular fractional area change (a load-dependent index of right ventricular inlet function). To distinguish between genuine right ventricular dysfunction and/or pathological increases in pulmonary vascular load, we will combine systolic pulmonary artery pressure and right ventricular end-systolic area to calculate right ventricular end-systolic pressure-area relation. Peak systolic tricuspid annulus velocity and conventional indices of left ventricular systolic and diastolic function will also be measured at baseline and peak stress according to the standard ABCDE-FGLPR protocol. Right ventricular free wall strain combined with interventricular septum strain will be assessed. Left ventricular function, wall motion score index and E/e' at baseline and peak stress.
SESPASM - SE for coronary vasospasm
The primary aim is to evaluate the feasibility and safety of hyperventilation and exercise ABCDE-SE in patients with angiographically normal coronary arteries and an intermediate-to-high pre-test probability of coronary vasospasm of epicardial arteries or microvasculature. The secondary aim is to assess the positivity rate of A and D criteria in these patients, compared to standard ECG criteria. The tertiary aim is to assess the prognostic value of the different responses of SE leading to SE-driven therapies. Only patients with strong (Class 1) indication to vasospasm testing according to the recent guidelines will be initially considered. Patients prepared for exercise testing will undergo vasospasm testing in the morning with hyperventilation. If negative or equivocal at 5 minutes after the end of hyperventilation, the patient will start exercise with the usual protocol. A sample size of 513 patients is required with a 5-year follow-up for the composite endpoint.

SE in heart donors
The examination of the heart starts with a resting transthoracic echocardiography. Exclusion criteria are: resting wall motion score index\>1.0; ejection fraction \<45%; diastolic dysfunction of grade 2 or more; hemodynamically significant (moderate or higher) valve regurgitation or stenosis; severe left ventricular hypertrophy (left ventricular mass index \>175 g/m2). A pharmacological SE with dipyridamole (0.84 mg/kg over 6 minutes) is recommended. The diagnostic end-points are stress-induced RWMA and abnormalities in global LVCR. All images will be analyzed as per guidelines similarly to the other projects, with emphasis on wall motion score index and LVCR based on ejection fraction and force. The hearts excluded from donation for RWMA or abnormal LVCR could however be collected for heart valve preparation and evaluated by coronary angiography and by pathological examination according to local facilities.
