Text: However, carvedilol improved the results of the quality-of-life questionnaire, reduced the mean (+ / - SD) slope of the minute ventilation (E) / carbon dioxide output (CO (2)) ratio (from 36. 4 + / - 8. 9 to 31. 7 + / - 3. 8 ; p < 0. 01) and reduced ventilation at the following times : at peak exercise (from 60 + / - 14 to 48 + / - 15 L/min ; p < 0. 05) ; during the intermediate phases of a ramp-protocol exercise ; and during the steady-state phase of a constant-workload exercise (from 42 + / - 14 to 34 + / - 13 L/min ; p < 0. 05, at third min).
