Abstract

(means, SD): (1) The mean ventilatory threshold preceded the ischaemic threshold in relation to exercise capacity (48 +/- 14 vs 55 +/- 20 watts; P < 0.05), VO2.kg-1 (10.0 +/- 2.2 vs 12.0 +/- 2.9 ml.kg-1.min; P < 0.05), HR (93 +/- 15 vs 100 +/- 16.min-1; P < 0.01), RPP (15095 +/- 4424 vs 17166 +/- 5245; P < 0.01) and blood lactate (1.28 +/- 0.53 vs 1.44 +/- 0.60 mmol.l-1; P < 0.05). (2) This relationship was observed more often in the subgroup of patients with angina during cardiopulmonary exercise testing or with myocardial infarction or with three-vessel disease than in patients without angina or infarction or with one- and two-vessel disease.(ABSTRACT TRUNCATED AT 250 WORDS)
