Limited data is available about the temporal trends in Primary Percutaneous coronary intervention from the Middle East region. In this study, we report procedural and clinical outcomes of the nationwide primary PCI program in Qatar.
This is a retrospective analysis of the national primary Percutaneous Coronary Intervention database in the state of Qatar between January 2015 and December 2021.
During the study period of seven years, 7000 patients underwent PPCI, with 95% being male. This gender observation remained constant throughout the study period. The mean age increased from 49+/-10 in 2016 to 56+/- 10 in 2021 ( p= 0.001 ). There was a significant increase in the documented history of diabetes from 25% to 32% (p= 0.001), hypertension from 26% to 35% ( p= 0.001 ), and smoking from 34% to 38% (p=0.009). Transradial access use increased from 56% to 76% ( p=0.001 ), while the contrast dose decreased from 147+/-69 to 117+/-69 ml (p=0.001). Door-to-balloon time trended from 54 minutes ( IQR 40-69) to 49 minutes ( IQR 37-64 ) p= 0.08. In-hospital mortality declined from 4.6 to 2.7 % (p= 0.09).
During the study period, there was a significant rise in the TRA approach and a substantial reduction in contrast use. Despite the increase in patients’ age and cardiovascular risk factors profile, there was a trend toward lower in-hospital mortality.
