BACKGROUND AND OBJECTIVES@#We sought to evaluate nationwide
trends, characteristics, and clinical outcomes in
patients undergoing
percutaneous coronary intervention (PCI) in
Korea.@*
METHODS@#From
National Health Insurance claims data in
Korea, 81,115
patients,
who underwent PCI for the first episode of
coronary artery disease between 2011 and 2015, were enrolled.
Patients were categorized into angina (n=49,288) or acute
myocardial infarction (AMI, n=31,887) groups and analyzed.@*RESULTS@#The mean age of
patients was 64.4±12.2 years and 56,576 (69.7%) were
men. Diabetes,
hyperlipidemia, and
hypertension were observed in 27,086 (33.4%), 30,675 (37.8%), and 45,389 (56.0%)
patients, respectively. There was a 10% increase in the number of
patients undergoing PCI for angina between 2011–2012 and 2014–2015 (11,105 vs. 13,261; p=0.021). However, the number of
patients undergoing PCI for AMI marginally decreased between 2011–2012 and 2014–2015 (8,068 vs. 7,823; p=0.052). In
procedures,
drug-eluting stent was the most frequently used
device (93.2%), followed by
balloon angioplasty (5.5%) and bare
metal stents (1.3%). The mean number of
stents per
patient was 1.39±0.64. At discharge, dual-anti
platelet therapy,
statin, beta-blockers, and
angiotensin converting enzyme inhibitor or
angiotensin receptor blocker were provided to 76,292 (94.1%), 71,411 (88.0%), 57,429 (70.8%), and 54,418 (67.1%)
patients, respectively. The mean in-
hospital and 1-year total medical
costs were 8,628,768±4,832,075 and 13,128,158±9,758,753 Korean Won, respectively.
In-hospital mortality occurred in 2,094
patients (2.6%).@*CONCLUSIONS@#Appropriate
healthcare strategies reflecting
trends, characteristics, and clinical outcomes of PCI are needed in
Korea.
