REDUCTION IN PLATELET COUNT IN POST CABG PATIENTS WITH OR WITHOUT IABP- AN EXPERIENCE AT AFIC/NIHD RAWALPINDI

Abstract

Objective: To study the reduction in platelet count in patients after coronary artery bypass grafting having IABP
placed peri operatively with and without IABP placed.
Study Design: Descriptive Study.
Place and Duration of Study: Armed Forces Institute of Cardiology/National Institute of Heart Diseases
(AFIC/NIHD) from Jan 2012 to Dec 2013.
Patients and Methods: All cases with intra-aortic balloon pump (IABP) placed peri operatively (coronary artery
bypass grafting, CABG) during this time period were examined in detail. Only those patients who had a platelet
count of 150,000 or more pre operatively were included in the study. Patients taking medicines pre operatively
that lead to decrease in platelet count were excluded. Platelet counts of each patient were analyzed till the third
post-operative day. One hundred and fifty patients were divided into two equal groups, group A without IABP
and group B with IABP.
Results: Patients without IABP (group A) pre operatively had mean platelet count of 223.57 ± 83.02, on first post
op day the mean platelet count was 171.0 ± 59.0 which was 76.48% of preoperative level, on second post op day
the mean platelet count was 168.1 ± 59.4 which was 75.20% of preoperative level and on third post op day the

Conclusion: Reduction in platelet count in post CABG patients is similar in both the groups i.e. in whom IABP is
and those patients who are not treated with IABP.
