ABSTRACT
Aim: To determine the clinical outcomes of patients who received bailout thrombectomy for primary percutaneous coronary intervention.
Study Design: Cross-sectional/observational
Place & Duration: Study was conducted at Cardiac Centre, Cardiology Department, Pakistan Institute of Medical Sciences (PIMS) Islamabad from January 2020 to December 2020 (for one year).
Methods: 200 hundred patients of both genders undergoing primary percutaneous coronary intervention(PPCI)for ST elevation myocardial infarction(STEMI) were analyzed in this study. All patients were divided into two groups. Group A contains 100 patients and received PPCI with bailout thrombectomy and Group B contains 100 patients and received PPCI alone. Informed written consent was taken. Outcomes such as mortality, re-infarction, heart failure, cardiogenic shock, renal impairment, excess bleeding, post procedure stroke and hospital stay were examined and compare between both groups.
Results: In Group A there were 53% males and 47% females with mean age 56.45+10.88 years. In Group B 55% were males and 45% were females with mean age 58.35+9.23 years. In Groups A there were more diabetic patients 45% than Group B 32% (p-value 0.005), Group B had more smokers 60%. There was a significant difference between group A and B regarding family history of coronary artery disease 35% vs 20% (p=0.003). In Group A 3% patients were died and in Group B 2% patients were died with no significant difference. Group A patients had more renal impairment 9% vs 5% and stroke 3% vs 1% than Group B. Hospital stay was high in Group A patients 7.12+2.05 vs 5.34+1.02 days of Group B.
Conclusion: It is concluded that patients received bailout thrombectomy for percutaneous coronary intervention (PCI) had high rate of comorbidities. There was no significant difference in term of mortality between both groups. However, patients with bailout thrombectomy had more renal impairment and post-procedure stroke.
