Aim: To study the clinico-angiographic profile, risk-factor profile, procedural and in-hospital outcomes of suspected STEMI patients undergoing Primary or Rescue percutaneous coronary intervention (PCI).

Methods: In this retrospective observational study, we reviewed the hospital database of 105 patients, who underwent primary or rescue PCI from May’19 to July’22. Data on demographic, clinico-angiographic and risk-factor profiles, procedural aspects and in-hospital outcomes was collected and analysed.

Results: Male preponderance was observed in our study (85.7%). The mean age of presentation was 54.62 ± 12.1 years. One-fifth of the cases were young males. Hypertension was the most prevalent risk factor followed by diabetes mellitus and tobacco use. Anterior wall MI was the most common presentation. The mean door-to-balloon time was 82.23 ± 70.95 minutes. Single vessel disease with LAD involvement was the commonest angiographic diagnosis followed by RCA, LCx, LMCA and ramus. 88.57% of cases underwent primary PCI; the rest underwent rescue PCI. The femoral approach was used in two-thirds of cases. TIMI III flow was achieved in 91.43% of cases. The overall in-hospital mortality was 5.71% secondary to cardiogenic shock, acute kidney injury, heart failure and ventricular arrhythmias. LV systolic dysfunction with LVEF<50% was observed in 90.48% of patients. 

Conclusion: Anterior wall MI and single vessel disease with LAD involvement were the commonest presentations, with favourable in-hospital outcomes. The mean door-to-balloon time was comparable with previous literature. Such a study could recognise clinical and procedural challenges and help create primary PCI networks in developing countries like India. Such networks can streamline and accelerate primary PCI management protocols for better clinical outcomes.
