What is the purpose of stress echocardiography?

The purpose of stress echocardiography is to assess heart function and structure under stress. This procedure involves using echocardiography to visualize the heart while the patient is subjected to physical stress, usually through exercise or pharmacologic agents. The goal is to determine how the heart performs under conditions that increase demand, which can reveal issues such as ischemia (reduced blood flow to the heart), valve problems, or other conditions that might not be apparent when the heart is at rest.

By comparing the heart's performance during rest and stress, healthcare providers can gather valuable information about the heart's health, its ability to pump blood, and how well the heart's chambers work under increased workload. This understanding is critical for diagnosing and managing various heart conditions, particularly in patients with symptoms of coronary artery disease or those who are at higher risk for cardiac events.

Routine health check-ups often focus on assessing risk factors and general heart health without the detail that stress testing provides. Measuring cholesterol levels is relevant but unrelated to echocardiography. Evaluating normal resting heart function provides important baseline information but does not inform how the heart reacts under stress, which is crucial for a comprehensive cardiac assessment.
