Differences in clinical characteristics and outcomes based on racial origin in an Australian PCI population.

Abstract

Background: There is no published Australian data regarding the incidence of PCI outcomes with respect to race. American registry data has shown that patients from some racial minorities have higher long-term mortality and MI rates when compared with Caucasians.

Methods: We analysed 18,538 patients undergoing PCI between 2005 and 2015. Clinical and procedural data, 30-day and 12-month outcomes were compared between Caucasian, Asian and South Asian (Indian/Sri Lankan/Pakistan/Bangladesh). Long-term mortality was compared using National Death Index linkage.

Results: South Asians were younger yet had significantly more diabetes and multivessel disease. Asian patients presented with fewer risk factors. Caucasians had the highest proportion of smokers and heart failure. Caucasians had significantly higher long-term mortality than Asian and South Asian patients. Amongst the patients with STEMI, there were no significant differences in both symptom and door-to-balloon times between races. There was no difference in 30-day and 12-month medication use.
