Data are presented as mean±standard deviation. Percentage of change is compared to the baseline value, calculated as: (51.74-32.49) ÷ 32.49. Group C: standard pharmacotherapy and placebo, Group M: standard pharmacotherapy and 25 μg milrinone slow IV bolus, PEFR: peak expiratory flow rate.
**Statistically highly significant.
