Moderate ischemic mitral regurgitation at rest is associated with multiple functional vulnerabilities during exercise stress echocardiography

Key Points

• To investigate the relationship between moderate ischemic mitral regurgitation at rest and functional vulnerabilities during exercise stress echocardiography.
• Evaluated individuals with moderate ischemic mitral regurgitation at rest during exercise stress echocardiography.
• Assessed changes in heart function and cardiac output during exercise.
• Patients with moderate ischemic mitral regurgitation showed significant declines in cardiac output during exercise stress.
• Functional vulnerabilities were more pronounced in individuals with moderate ischemic mitral regurgitation compared to those without.
