Heart, front view

MUGA test

Cardiac blood pooling imaging; Heart scan - nuclear; Radionuclide ventriculography (RNV); Multiple gate acquisition scan (MUGA)

Normal results indicate normal heart function, or a normal cardiac response to exercise.

Abnormal results may indicate poor pumping function, a prior heart attack (myocardial infarction), blockages in the coronary arteries (coronary artery disease), heart valve disease, or other cardiac disorders associated with weakening of the heart function.

Additional conditions under which the test may be performed:

• Atrial septal defect
• Dilated cardiomyopathy
• Heart failure
• Idiopathic cardiomyopathy
• Mitral stenosis
• Peripartum cardiomyopathy
• Senile cardiac amyloid
