Why the study?

Does intracoronary electrography improve the detection of myocardial ischemia compared to surface ECG monitoring in patients undergoing single lesion coronary angioplasty?

Structured PICO

Does intracoronary electrography improve the detection of myocardial ischemia compared to surface ECG monitoring in patients undergoing single lesion coronary angioplasty?

P

Population

65 patients (from an initial 73) undergoing single lesion coronary angioplasty. 8 patients were excluded due to transient intraventricular conduction disturbances during balloon inflation.

I

Intervention

Intracoronary electrography during balloon inflation

C

Comparator

Standard technique of surface ECG monitoring (four representative surface leads)

O

Outcome

Percentage that produced a≥ mm ST segment elevation, the time to the appearance of a≥ mm ST segment elevation, and the maximal ST segment elevationsurrogate

Intracoronary electrography enhances the detection of myocardial ischemia during circumflex and left anterior descending coronary angioplasty compared to limited surface ECG monitoring, but is less effective during right coronary angioplasty.

Limitations

Only four surface leads were monitored

Answers are grounded in this paper and cite their sources.

Implication

May improve ischemia detection during circumflex angioplasty; hypothesis-generating and should not yet change practice.
