Background: The number of elderly patients who undergo percutaneous coronary intervention (PCI) is increasing, and application of bleeding avoidance strategies such as transradial intervention (TRI) is of utmost importance. We aimed to clarify the trend of real-world TRI application within the elderlies, in relation to the calculated pre-procedural bleeding risk in a Japanese contemporary PCI registry.
Methods: Out of 16,563 patients, 4,167 elderly patients (age >70: 25.1%) who underwent PCI between 2009-2013 were evaluated (mean age 77.8 ±4.99 years old, and 20.0% were female). We calculated the NCDR Cath PCI Bleeding Risk Score for each patient and divided the patients into high vs. low bleeding risk group.
Results: The median score for the NCDR Cath PCI Bleeding Risk Score was 80 (70-95) points (average expected bleeding rate 9.90%). In the high-risk group, the number of TRIs increased from 26.5% to 37.6% during the studied period, and the bleeding rate decreased from 7.4% to 4.0% (Figure 1-a). In the low-risk group, the number of TRIs also increased from 23.1% to 42.5% but the trend in bleeding rate was not evident (Figure 1-b).
Conclusions: Implication of the TRI in elderly patients is steadily increasing in Japan, and the observed bleeding rate is decreasing proportionally, particularly in high-risk patients.
