The Current Status of Percutaneous Coronary Intervention in Korea: Based on Year 2014 & 2016 Cohort of Korean Percutaneous Coronary Intervention (K-PCI) Registry.

ABSTRACT:

Background and objectives

In this second report from Korean percutaneous coronary intervention (K-PCI) registry, we sought to describe the updated information of PCI practices and Korean practice pattern of PCI (KP3).

Methods

In addition to K-PCI registry of 2014, new cohort of 2016 from 92 participating centers was appended. Demographic and procedural information, as well as in-hospital outcomes, of PCI was collected using a web-based reporting system. KP3 class C was defined as any strategy with less evidence from randomized trials and more aggressive for PCI than medical therapy or bypass-surgery.

Results

In 2016, total 48,823 PCI procedures were performed at 92 participating centers. Mean age of the patients was 65.7±11.6 years, and 71.7% were males. Overall patient characteristics and PCI practices in 2016 were similar to those in 2014. The biggest change was the decrease in the in-hospital occurrence of myocardial infarction (MI;1.6%?0.7%, p<0.001). Many associations between PCI volumes and demographic/procedural characteristics observed in 2014 have disappeared. The median of door-to-balloon time was 62 minutes, and 83.3% of ST-elevation MI patients received primary PCI within 90 minutes, while the median of total ischemic time was 168 minutes and patients who had total ischemic time within 120 and 180 minutes were 29.1% and 54.1%, respectively. The proportion of KP3 class C cases in non-acute coronary syndrome patients decreased from 13.5% in 2014 to 12.1% in 2016 (p<0.001).

Conclusions

In this second report from K-PCI registry, we described the current practices of PCI and changes from 2014 to 2016 in Korea.

Project description:ObjectiveTo evaluate the clinical utility of individualising dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in an all-comers population, including ST-elevation myocardial infarction (STEMI) patients.SettingTertiary care single centre registry.Participants1008 consecutive PCI patients with stent implantation, without exclusion criteria.InterventionPeri-interventional individualisation of DAPT, guided by multiple electrode aggregometry (MEA), to overcome high on-treatment platelet reactivity (HPR) to ADP-induced (≥50 U) and arachidonic acid (AA)-induced aggregation (>35 U).Outcome measuresThe primary efficacy end point was definite stent thrombosis (ST) at 30 days. The primary safety end point was thrombolysis in myocardial infarction (TIMI) major and minor bleeding. Secondary end points were probable ST, myocardial infarction, cardiovascular death and the combined end point: major cardiac adverse event (MACE).Results53% of patients presented with acute coronary syndrome (9% STEMI, 44% non-ST-elevation). HPR to ADP after 600 mg clopidogrel loading occurred in 30% of patients (73±19 U vs 28±11 U; p<0.001) and was treated by prasugrel or ticagrelor (73%), or clopidogrel (27%) reloading (22±12 U; p<0.001). HPR to ADP after prasugrel loading occurred in 2% of patients (82±26 U vs 19±10 U; p<0.001) and was treated with ticagrelor (34±15 U; p=0.02). HPR to AA occurred in 9% of patients with a significant higher proportion in patients with HPR to ADP (22% vs 4%, p<0.001) and was treated with aspirin reloading. Definite ST occurred in 0.09% of patients (n=1); probable ST, myocardial infarction, cardiovascular death and MACE occurred in 0.19% (n=2), 0.09% (n=1) and 1.8% (n=18) of patients. TIMI major and minor bleeding did not differ between patients without HPR and individualised patients (2.6% for both).ConclusionsIndividualisation of DAPT with MEA minimises early thrombotic events in an all-comers PCI population to an unreported degree without increasing bleeding. A randomised multicentre trial utilising MEA seems warranted.Trial registration numberhttp://www.clinicaltrials.gov; NCT01515345.

Project description:BackgroundPercutaneous coronary intervention (PCI) has been shown to improve health-related quality of life (HRQoL) in patients with coronary artery disease (CAD). The objectives of this study were to assess the changes in HRQoL and factors influencing these changes in CAD patients after undergoing PCI.MethodsData from a nationwide PCI registry across 39 hospitals in Thailand were collected in 2018-2019, including baseline characteristics, comorbid diseases, angiographic CAD severity, procedural details, and type of health insurance. HRQoL, as measured by utility scores, was determined in all patients using the Thai version of EQ-5D-5l at admission, discharge, and 6 and 12 months after discharge. The effects of time after PCI procedure and various factors on mean utility scores were assessed using a mixed-effect linear regression model.ResultsA total of 19,701 patients were included in the analysis; they had a mean age of 64.2 ± 11.7 years and were predominantly (69.1%) male. Following PCI, the mean utility scores increased from 66.6 ± 19.6 at admission to 81.9 ± 13.8 at discharge, and remained stable at 6 and 12 months (86.1 ± 12.3 and 88.0 ± 11.7, respectively). After adjusting for potential confounding variables, several factors were found to be independently associated with improved HRQoL, including angiographic success, male gender, overweight status, dyslipidemia, and radial access. Six other factors were associated with less improved HRQoLs, including cardiogenic shock/IABP support, old age, CKD, clinical presentation (STEMI and NSTEMI), prior cerebrovascular disease, and heart failure. There were no associations of CAD severity and procedural details with HRQoL. No differences were found related to type of health insurance, except that patients who were uninsured or self-pay tended to have less improvement in HRQoL.ConclusionHRQoL improved significantly after PCI in these subjects, as observed through 1 year of follow-up. Identifying the factors influencing these improvements may assist clinicians in tailoring patient interventions to optimise quality of life after PCI.
