Which Test Should I Order for an Inpatient Evaluation of Cardiac Ischemia?

Area of Science:

• Cardiology
• Diagnostic Imaging
• Internal Medicine

Background:

• Cardiac ischemia and obstructive coronary artery disease (CAD) are common in hospitalized patients.
• Numerous diagnostic testing options are available, complicating clinical decision-making.
• Accurate risk stratification is essential for selecting the most appropriate cardiac test.

Purpose of the Study:

• To provide a guide for selecting appropriate cardiac ischemia testing in the inpatient setting.
• To differentiate between stress (functional) and anatomical testing modalities.
• To illustrate test selection considerations using clinical case examples.

Main Methods:

• Review of current diagnostic testing strategies for cardiac ischemia.
• Categorization of tests into stress testing (functional) and anatomical testing.
• Application of risk stratification principles to test selection.

Main Results:

• Stress testing evaluates for ischemia, with or without imaging.
• Anatomical testing visualizes obstructive CAD.
• Test selection depends on patient-specific factors and risk assessment.

Conclusions:

• Choosing the optimal test for inpatient cardiac ischemia evaluation requires careful consideration of available options.
• Understanding the distinct roles of stress and anatomical testing is key.
• Risk stratification guides the selection of the most informative diagnostic test.
