Обзор
Exercise echocardiography is a widely used non-invasive test that evaluates cardiac structure and function during physical stress. It provides important information on myocardial ischemia, cardiac performance, hemodynamic responses, and exercise capacity in patients with a broad range of heart diseases. However, real-world prospective data integrating exercise echocardiographic findings across both ischemic and non-ischemic heart disease remain limited. This prospective observational registry aims to systematically collect clinical, exercise, and echocardiographic data from patients undergoing clinically indicated exercise echocardiography. The registry includes patients with suspected or established ischemic heart disease as well as those with non-ischemic cardiac conditions, such as cardiomyopathies, heart failure, valvular heart disease, and exercise-related symptoms. The collected data will be used to evaluate exercise-induced changes in cardiac structure and function, identify phenotypes associated with adverse clinical outcomes, and improve risk stratification in routine clinical practice. The registry is observational in nature and does not alter standard clinical care.
Подробное описание
Exercise echocardiography is an established diagnostic and prognostic tool in cardiovascular medicine, providing dynamic assessment of myocardial function, hemodynamics, and functional capacity under physiological stress. While its role in ischemic heart disease is well recognized, exercise echocardiography is increasingly used in patients with non-ischemic heart disease, including heart failure, cardiomyopathies, valvular disorders, and unexplained exercise intolerance. Despite its broad clinical application, contemporary prospective real-world registries that comprehensively evaluate exercise echocardiographic findings across both ischemic and non-ischemic heart disease are scarce.
The Exercise Echocardiography Registry for Ischemic and Non-Ischemic Heart Disease is a prospective, observational registry designed to collect standardized clinical, exercise testing, and echocardiographic data from patients undergoing clinically indicated exercise echocardiography at a tertiary care center. Participation in the registry does not require any additional diagnostic procedures beyond routine clinical practice.
\<Study Population\>
Eligible participants include adult patients referred for exercise echocardiography for evaluation of:
* Suspected or known ischemic heart disease * Non-ischemic heart disease, including cardiomyopathy, heart failure, valvular heart disease, or structural heart disease * Exercise-related symptoms such as dyspnea, chest discomfort, or reduced exercise tolerance
\<Data Collection\>
The registry prospectively collects:
* Baseline clinical characteristics, including cardiovascular risk factors and comorbidities * Indications for exercise echocardiography * Exercise test parameters, such as exercise modality, workload, blood pressure response, heart rate response, and symptoms during exercise * Resting and post-exercise echocardiographic measurements, including left ventricular systolic and diastolic function, wall motion, valvular hemodynamics, and pulmonary pressure estimates when available * Clinically relevant follow-up outcomes obtained through medical record review
\<Study Objectives\>
The primary objectives of this registry are:
* To characterize exercise-induced echocardiographic responses in patients with ischemic and non-ischemic heart disease * To assess the association between exercise echocardiographic findings and subsequent clinical outcomes * To evaluate the prognostic value of exercise echocardiography in real-world clinical practice
\<Study Design\> This is a non-interventional, observational registry. All clinical evaluations and management decisions are determined by the treating physicians according to standard care. No experimental interventions are introduced as part of this study.
\<Significance\> By integrating exercise performance, hemodynamic responses, and echocardiographic findings, this registry aims to enhance understanding of the clinical utility of exercise echocardiography across a broad spectrum of heart disease. The results are expected to support improved risk stratification, inform future hypothesis-driven studies, and contribute to evidence-based use of exercise echocardiography in routine cardiovascular care.
