Exercise Echocardiography Registry for Ischemic and Non-Ischemic Heart Disease

Summary

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.

Eligibility

Inclusion Criteria:

* Adults aged 18 years or older
* Patients referred for clinically indicated exercise echocardiography as part of routine clinical care
* Patients evaluated for suspected or known ischemic heart disease, or non-ischemic heart disease, including but not limited to: Cardiomyopathy, Heart failure, Valvular heart disease, Structural heart disease
* Ability to perform exercise-based stress testing using treadmill or bicycle protocols
* Availability of baseline clinical data and interpretable echocardiographic images obtained during rest and exercise
* Provision of informed consent, or eligibility for consent waiver in accordance with institutional review board approval

Exclusion Criteria:

* Inability to perform exercise testing due to non-cardiac limitations, such as severe orthopedic, neurologic, or pulmonary conditions
* Poor echocardiographic image quality that does not allow meaningful interpretation of exercise-induced changes
* Any condition deemed by the treating physician to make participation inappropriate or unsafe, even within an observational framework
