Myocardial perfusion imaging in the elderly: a review

Area of Science:

• Cardiology
• Nuclear Medicine
• Geriatrics

Background:

• Coronary artery disease (CAD) significantly impacts elderly morbidity and mortality.
• Aging populations and advanced treatments lead to increased referrals for CAD diagnosis in older adults.
• Diagnosing CAD in the elderly is challenging due to atypical symptoms.

Purpose of the Study:

• To review stress testing combined with myocardial perfusion imaging (MPI) for elderly patients.
• To discuss the diagnostic accuracy and prognostic value of MPI in this demographic.
• To highlight the benefits of electrocardiogram-gated MPI.

Main Methods:

• Overview of various stress modalities used in conjunction with MPI.
• Focus on technetium-99m ligands for myocardial perfusion imaging.
• Inclusion of electrocardiogram-gated imaging for enhanced specificity and functional assessment.

Main Results:

• Electrocardiogram-gated MPI enhances specificity for CAD detection.
• Simultaneous assessment of left ventricular function is possible with gated MPI.
• MPI demonstrates diagnostic and prognostic value in elderly patients with suspected CAD.

Conclusions:

• Myocardial perfusion imaging is a valuable tool for diagnosing CAD in the elderly.
• Electrocardiogram-gated MPI offers improved accuracy and functional insights.
• MPI aids in risk stratification and management of coronary artery disease in older adults.
