Factors for In-hospital Mortality after Percutaneous Coronary Intervention in Patients with ACS

Abstract

Background: Percutaneous coronary intervention (PCI) is a nonsurgical technique for treating obstructive coronary artery disease. Aim: To assess the causes / factors leading to mortality after percutaneous coronary intervention Study design: Cross sectional study Setting: Department of Cardiology, Punjab institute of cardiology, Lahore. Duration: Six months i.e. from1stJuly 2020 to 31stDecember 2020. Methods: Medical records of 100 cases who dies after PCI for acute coronary syndrome were taken from record center. Medical record of patients aged 40 to 70 years, both genders underwent PCI and did not survived after PCI were included. Location of lesion, and severity of vessel disease, type of procedure and acute renal failure were considered as factors of mortality and were noted on proforma while analyzed in SPSS 20. Results: The mean age of the patients was 54.20 ± 8.84 years. There were 42(42%) males and 58(58%) females. History of smoking was positive in 48 (48%) cases, diabetes in 51(51%) and hypertension in 55(55%) cases. Among the factors, old age (≥50 years) was observed in 64(64%) patients while 36(36%) had age <50 years. There were 39(39%) patients who underwent PCI under emergency situation and 61(61%) patients had PCI under elective circumstances. Acute renal failure was noticed in 37(37%) patients. There were more patients of right coronary artery disease i.e. 54(54%) who underwent PCI. Conclusion: Out of all factors leading to mortality after PCI, older age at the time of PCI is the most common factor, followed by right coronary artery disease and multi-vessel disease.
