Outcomes of PCI of all comers: the experience of a Kuwaiti independent healthcare institution.

We present the cumulative percutaneous coronary intervention (PCI) data of all comers (stable angina and acute coronary syndromes [ACS]) who presented to Hadi Clinic between January 2018 and December 2020. As a low-volume PCI centre in the Middle East, we wanted to find out if the outcomes of our PCI procedures are different from those of high-volume PCI centres in the UK and the Western world. Prospectively collected data of all comers for PCI (urgent and elective) were retrospectively analysed. Preprocedural data included patients' baseline characteristics (age, gender, clinical presentation and comorbidities). Intra-procedural data included access route, coronary anatomy, lesion complexity, number of stents deployed, door-to-balloon time for primary PCI, and any intraprocedural complications. Postprocedural data included average length of in-hospital stay, intra-hospital morbidity and mortality, and mortality or admission with ACS 12-36 months after the index procedure. A total of 567 patients underwent coronary catheterisation for the three-year period between January 2018 and December 2020. Mean age was 60.9 ± 9.4 years, and 459/567 (81.0%) were male. Comorbidities included dyslipidaemia 515/567 (90.9%), hypertension 460/567 (81.2%), diabetes 346/567 (61%), known prior coronary disease 250/567 (44.2%), and smoking 188/567 (33.1%). Clinical presentation was stable angina 130/567 (22.9%), non-ST-elevation acute coronary syndrome (NSTEACS) 312/567 (55%), ST-elevation myocardial infarction (STEMI) 125/567 (22.0%), and STEMI with cardiogenic shock 13/125 (10.4%). The radial approach was used in 544/567 (95.94%), the average SYNTAX score was 34.8 ± 9.6, and the average number of stents 2.6. The total number of PCI was 367 (122.3 annually) with PCI procedural complete success in 349/367 (95.1%), partial success 5/367 (1.36%), PCI procedural complications 3/367 (0.82%), PCI in-hospital mortality 1/367 (0.27%), door-to-balloon time for primary PCI 31.8 ± 12.2 minutes, subsequent admission with ACS after 12-36 months 2/367 (0.54%), and post-discharge mortality after 12-36 months 1/367 (0.27%). In conclusion, our patient population have more comorbidities and more complex coronary disease in comparison to their western counterparts. Our annual PCI numbers have been significantly lower than the recommended 400 minimum cut-off figure, yet we have achieved comparable outcomes to those of larger institutions of the western world.
