TL;DR

Selective coronary arteriography has confirmed previous doubts regarding the diagnostic reliability of the postexercise electrocardiogram in the individual patient with chest pain and indicated the presence and severity of coronary artery disease.

Abstract

Seventy-five patients with chest pain were studied with a double Master exercise test (post-exercise electrocardiogram) and coronary cine-arteriography to determine the correlation between these two methods of indicating the presence and severity of coronary artery disease. In 33 patients, the description of the chest pain was not that of classic angina pectoris. In this group, coronary cinearteriography revealed no disease while 10 patients had a positive double Master exercise test. Forty-two patients had pain that was quite characteristic of angina pectoris. In this group, coronary artery disease was demonstrated in all patients by coronary cinearteriography while 24 of these patients had a negative Master test. Study of the coronary arteriograms showed no significant difference in the severity and distribution of the disease between patients with a positive postexercise electrocardiogram and those with a negative postexercise electrocardiogram. The incidence of demonstrable collateral channels was identical in both groups. Selective coronary arteriography has confirmed previous doubts regarding the diagnostic reliability of the postexercise electrocardiogram in the individual patient with chest pain.

The results of a recently published comparative study between the double Master two-step test and the exercise on a treadmill, which was sufficiently long to achieve the steady state, show that the procedure was of short duration and did not permit the achievement of a steady state.

A double-blind study was made to evaluate the two-step exercise electrocardiographic test (Master) as a means of differentiating between anginal and nonanginal chest pain in 100 consecutive patients, finding that a high percentage of false-positive results inNonanginal cases and a number of false negatives in anginal cases greatly impaired the usefulness of the test for this purpose.
