Patients having ARF because of CAD and using rate limiting drug were included. Demographics, reason for RLD use, cause of ARF ,comorbitities, APACHE II score, application and duration of noninvasive or invasive mechanical ventilation ,heart rate,CRP levels,biochemistry values and complete blood count,length of ICU stay,and mortality were recorded.Patients were divided in two groups as group 1(using only beta blocker as RLD) and Group 2 (using drugs other than beta blocker).Results:188 patients (46 female) enrolled to study. Age, gender, co-morbities, duration and type of MV application were similar between Group 1(n=74) and Group 2(n=114).Reasons for RLD use were different between two groups.Atrial fibrillation 23% and %30, supraventricular tachycardia 41.9 % and 54.4%, congestive heart failure 17.6% and 4.4% for Group 1 and 2 respectively.Median length of ICU stay (6[4-10] and 7[4-10] day p=0.70),APACHE II score (19[17-23]) and 20[16-24] p=0.88),mortality (n=13 17.6% and n=18 15.8% p=0.75) were also similar.Conclusion: In chronic airway disease, despite the development of ARF, there is no difference between outcomes of use of beta blockers and other RLD for treatment of tachycardia.
