Abstract

We studied 34 patients with proven coronary heart disease to determine whether the presence or absence of angina pectoris during exercise testing was associated with greater disease, ST segment depression or fall in left ventricular ejection fraction. Angina pectoris was the limiting symptom in 19 and fatigue/breathlessness in 15 patients. Exercise time [421(31) vs. 455(64) s], ST depression [1.4(0.3) vs. 1.1(0.3)mm], fall in left ventricular ejection fraction [13(2) vs. 12(2)] and coronary score and fall in left ventricular ejection fraction [15(2) vs. 8(3), P less than 0.02]. The degree of ST segment depression correlated with the coronary score (r = 0.6) and fall in left ventricular ejection fraction (r = 0.5). ST segment depression but not angina pectoris during exercise predicted the extent of disease and its functional consequences.
