Short Term Outcome of Percutaneous Coronary Intervention in Anaemic Patients Presenting with Coronary Artery Diseases

Background: Percutaneous coronary intervention (PCI) has been an effective and widely used treatment for patients with coronary artery disease (CAD). The presence of anaemia in critically ill patients undergoing surgical procedures has been associated with worse clinical outcomes.

Hence, the current study was conducted to assess short term outcome of percutaneous coronary interventions in anaemic patients presenting with coronary artery diseases.

Methods: This prospective observational study enrolled 200 patients who underwent PCI. Patients were classified into 2 groups: anaemic patients and non-anaemic patients. The anaemic patients were furtherly be classified according to severity of anaemia into 3 grades mild anaemia, moderate anaemia, and severe anaemia.

All cases were subjected to complete history taking, clinical examination and baseline laboratory tests: including CBC, serum urea and creatinine, cardiac enzymes include serum troponin, CK-MB and standard 12-lead ECG.

Results: The mean Heart Rate was statistically significantly higher in the anaemic group as compared with the non-anaemic group. The mean Ejection Fraction was statistically significantly lower in the anaemic group as compared with the non-anaemic group. The percentage of LM affection in the anaemic group was statistically significantly higher as compared with the non-anaemic group. The incidence of arrythmia in the anaemic group was statistically significantly higher as compared with the non-anaemic group. Severe anaemic and low EF% patients were associated with higher incidence of stroke and MI.

Conclusions: Patients with baseline anaemia before PCI have a higher incidence of PCI associated complications. Therefore, anaemia could be a predictor of PCI related complications.
