Why the study?

Does a 36-lead body surface mapping system improve the detection of ST-segment deviations compared to standard 12-lead ECG in patients with ischemic heart disease?

Structured PICO

Does a 36-lead body surface mapping system improve the detection of ST-segment deviations compared to standard 12-lead ECG in patients with ischemic heart disease?

P

Population

90 patients with clinically evident ischemic heart disease (46 with angina pectoris [AP], 44 with old myocardial infarction [OMI]) who showed ≥0.1mV ST deviation on 36-lead exercise ECG. Excluded: valvular disease, hypertrophic cardiomyopathy, bundle branch block. AP group: mean age 56, 39 male/7 female. OMI group: mean age 58, 41 male/3 female.

I

Intervention

Exercise stress testing (treadmill, Bruce protocol) using a 36-lead body surface mapping system

C

Comparator

Simultaneously recorded modified 12-lead ECG

O

Outcome

Detection rate and optimal lead location for ST-segment deviation (depression, elevation, or both)surrogate

Implication

While lead V5 is sufficient for detecting exercise-induced ST depression, detecting ST elevation requires additional leads (right precordial, high precordial, aVL, inferior, posterior), especially in patients with prior myocardial infarction or variant angina.
