Implication

CM5 may aid sensitive ischemia detection in exercise testing; leaves open validation versus standard leads in CAD.

Structured PICO

Does bipolar lead CM5 accurately detect ST segment changes compared to standard electrocardiographic leads in patients with coronary artery disease?

Population

43 patients with coronary artery disease, including 30 studied during exercise tests (with ST segment depression >0.5 mm in standard leads) and 13 studied during percutaneous transluminal coronary angioplasty (with ST segment change in standard leads).

Intervention

Electrocardiographic recording using bipolar lead CM5

Comparator

Standard electrocardiographic leads (I, II, III, V2, V5)

Outcome

Sensitivity and magnitude of ST segment changessurrogate

Bipolar lead CM5 is highly sensitive for detecting subendocardial ischemia during everyday activities, though it may miss changes due to right coronary artery occlusion.
