Cost-effectiveness of imaging modalities in coronary heart disease: A comprehensive review

Area of Science:

• Cardiology
• Medical Imaging
• Health Economics

Background:

• Cardiovascular diseases (CVDs) present significant global health and economic challenges.
• Myocardial Perfusion Imaging (MPI) using SPECT and PET is crucial for diagnosing and managing coronary heart disease (CHD).
• Increasing healthcare costs necessitate re-evaluating the cost-effectiveness of nuclear cardiology techniques.

Purpose of the Study:

• To conduct an economic evaluation of various imaging modalities used in diagnosing and managing CHD.
• To summarize key studies assessing the cost-effectiveness of different imaging techniques in cardiology.
• To identify optimal imaging strategies for improving both clinical outcomes and economic efficiency in CHD management.

Main Methods:

• Review of existing literature on the cost-effectiveness of cardiac imaging modalities.
• Analysis of studies comparing Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) in the context of CHD.
• Synthesis of data considering factors like institutional resources, clinical setting, and healthcare systems.

Main Results:

• Significant heterogeneity exists in current cost-effectiveness data for individual imaging modalities.
• Factors such as operator expertise, patient setting (inpatient/outpatient), and healthcare reimbursement structures influence cost-effectiveness.
• Definitive conclusions on the superiority of any single modality are not yet possible due to data variability.

Conclusions:

• A comprehensive multimodality imaging strategy is recommended for managing CHD.
• Integrating various imaging techniques can enhance diagnostic accuracy and economic value.
• This approach promises improved clinical outcomes and more efficient healthcare resource utilization in cardiology.
