Coronary Catheterization and Percutaneous Coronary Intervention in China: 10-Year Results From the China PEACE-Retrospective CathPCI Study.

ABSTRACT: The use of coronary catheterization and percutaneous coronary intervention (PCI) is increasing in China, but, to date, there are no nationally representative assessments of the quality of care and outcomes in patients undergoing these procedures.To assess the quality of care and outcomes of patients undergoing coronary catheterization and PCI in China.In a clinical observational study (China PEACE [Patient-Centered Evaluative Assessment of Cardiac Events]-Retrospective CathPCI Study), we used a 2-stage, random sampling strategy to create a nationally representative sample of 11 241 patients undergoing coronary catheterization and PCI at 55 urban Chinese hospitals in calendar years 2001, 2006, and 2011. Data analysis was performed from July 11, 2014, to November 20, 2015.Patient characteristics, treatment patterns, quality of care, and outcomes associated with these procedures and changes over time.Of the 11?241 patients included in the study, the samples included, for 2001, 285 women (weighted percentage, 28.6%); for 2006, 826 women (weighted percentage, 32.2%), and for 2011, 2588 women (weighted percentage, 35.7%). Mean (SD) ages were 58 (8), 60 (11), and 61 (11) years, respectively. Between 2001 and 2011, estimated national rates of hospitalizations for coronary catheterization increased from 26?570 to 452 784 and for PCI, from 9678 to 208 954 (17-fold and 21-fold), respectively. More than half of stable patients undergoing coronary catheterization had nonobstructive coronary artery disease; this amount did not change significantly over time (2001: 60.3% [95% CI, 56.1%-64.5%]; 2011: 57.5% [95% CI, 55.8%-59.3%], P?=?.05 for trend). The proportion of PCI procedures performed via radial approach increased from 3.5% (95% CI, 1.7%-5.3%) in 2001 to 79.0% (95% CI, 77.7%-80.3%) in 2011 (P?

Project description:ImportanceDespite a rapid increase in percutaneous coronary intervention (PCI) procedures in China, little is known about patient-reported health status before and after PCI in patients without acute myocardial infarction (AMI).ObjectiveTo describe self-perceived angina-specific health status prior to PCI and 1 year after the procedure in patients without AMI in China.Design, setting, and participantsThe China Patient-Centered Evaluative Assessment of Cardiac Events (PEACE) Prospective Study of PCI was a population-based, multicenter cohort study of a consecutive sample of 1611 patients without AMI undergoing elective PCI. Participants were enrolled from 40 hospitals in 18 provinces in China from December 2012 to August 2014. Participants were eligible if they underwent PCI for stable and unstable angina and did not have AMI. Participants were excluded if they died in hospital, withdrew from follow-up, or had missing data on self-reported health status at baseline or at 1 year after PCI. The date of the analysis was September 15, 2018.ExposuresPercutaneous coronary intervention for ischemic heart disease.Main outcomes and measuresAngina frequency and angina-related quality of life were assessed with the Seattle Angina Questionnaire (SAQ) immediately prior to PCI and 1 year after the procedure. Either (1) an increase in the SAQ Angina Frequency score of 10 or more points or (2) an increase in the SAQ Quality-of-Life score of 10 or more points was considered to represent clinically significant improvement.ResultsOf 1611 patients, 520 (32.3%) were women; mean (SD) age was 61.3 (9.8) years. Among these patients, 443 (27.5%) had stable coronary artery disease and 1168 (72.5%) had unstable angina. One hundred fourteen of 443 patients undergoing PCI for stable coronary artery disease (25.7%) and 175 of 1168 undergoing PCI for unstable angina (15.0%) had no reported angina symptoms at the time of the procedure (SAQ Angina Frequency score = 100). Moreover, 18% of all patients (290) had minimal angina symptoms (SAQ Angina Frequency score >90) and, thus, no potential for substantial clinical improvement. Patients with smaller clinical improvements in angina symptom burden at 1 year following PCI had significantly higher baseline SAQ scores for all scales than patients with greater clinical improvement, but generally similar sociodemographic and procedural characteristics.Conclusions and relevanceIn this study, 25.7% of patients undergoing PCI for stable coronary artery disease had no reported angina symptoms at the time of the procedure. Patients with smaller clinical improvements in angina symptom burden had higher baseline SAQ scores, which highlights the importance of ascertaining impairment from angina among patients without AMI prior to performing PCI.

Project description:Background Sex differences in health status outcomes after percutaneous coronary intervention among patients without acute myocardial infarction are not well described. Methods and Results A total of 2237 patients (33.4% women) without acute myocardial infarction undergoing percutaneous coronary intervention were enrolled from 39 Chinese tertiary hospitals in the PEACE (China Patient-centered Evaluative Assessment of Cardiac Events) prospective percutaneous coronary intervention study. Data were collected immediately before and 1 year following percutaneous coronary intervention. Health status was measured using the disease-specific Seattle Angina Questionnaire (SAQ) Angina Frequency and Quality of Life domains, as well as the SAQ Summary Score. Among the study population, women were older, more often single, had lower levels of education, and had a higher prevalence of cardiac risk factors such as hypertension and diabetes mellitus. Women had lower mean 1-year SAQ Angina Frequency scores (mean±SD, 91.0±17.3 versus 93.9±13.3; P<0.01), SAQ Quality of Life scores (mean±SD, 67.3±23.0 versus 70.6±21.6; P<0.01), and SAQ Summary Scores (mean±SD, 81.6±13.8 versus 84.8±11.9; P<0.01), a difference of marginal clinical significance that persisted after multivariable adjustment. A slightly larger improvement in the SAQ Summary Score was observed in women as compared with men (20.9±22.6 versus 18.5±21.3; P=0.007) in unadjusted analysis. However, women were less likely to achieve clinically significant improvement in SAQ Angina Frequency (adjusted odds ratio, 0.67; 95% CI, 0.45-1.00) and SAQ Quality of Life (adjusted odds ratio, 0.73; 95% CI, 0.56-0.96) after adjustment. Conclusions There were no clinically significant differences in 1-year health status outcomes and improvement in health status by sex among patients without acute myocardial infarction following percutaneous coronary intervention. However, female sex was associated with poorer 1-year health status and a lower likelihood of experiencing clinically improvement in health status.

Project description:BackgroundThe number of percutaneous coronary interventions (PCI) in China has increased more than 20-fold over the last decade. Consequently, there is a need for national-level information to characterize PCI indications and long-term patient outcomes, including health status, to understand and improve evolving practice patterns.ObjectivesThis nationwide prospective study of patients receiving PCI is to: (1) measure long-term clinical outcomes (including death, acute myocardial infarction [AMI], and/or revascularization), patient-reported outcomes (PROs), cardiovascular risk factor control and adherence to medications for secondary prevention; (2) determine patient- and hospital-level factors associated with care process and outcomes; and (3) assess the appropriateness of PCI procedures.MethodsThe China Patient-centered Evaluative Assessment of Cardiac Events (PEACE) Prospective Study of PCI has enrolled 5,000 consecutive patients during 2012-2014 from 34 diverse hospitals across China undergoing PCI for any indication. We abstracted details of patient's medical history, treatments, and in-hospital outcomes from medical charts, and conducted baseline, 1-, 6-, and 12-month interviews to characterize patient demographics, risk factors, clinical presentation, healthcare utilization, and health status using validated PRO measures. The primary outcome, a composite measure of death, AMI and/or revascularization, as well as PROs, medication adherence and cardiovascular risk factor control, was assessed throughout the 12-month follow-up. Blood and urine samples were collected at baseline and 12 months and stored for future analyses. To validate reports of coronary anatomy, 2,000 angiograms are randomly selected and read by two independent core laboratories. Hospital characteristics regarding their facilities, processes and organizational characteristics are assessed by site surveys.ConclusionChina PEACE Prospective Study of PCI will be the first study to generate novel, high-quality, comprehensive national data on patients' socio-demographic, clinical, treatment, and metabolic/genetic factors, and importantly, their long-term outcomes following PCI, including health status. This will build the foundation for PCI performance improvement efforts in China. © 2016 The Authors. Catheterization and Cardiovascular Interventions. Published by Wiley Periodicals, Inc.
