Insights
The Hellenic Heart Registry on Percutaneous Coronary Interventions (HHR-PCI) tracked over 3400 patients undergoing PCI in Greece. It provided key insights into interventional cardiology practices and outcomes in the country.
Area of Science:
- Cardiology
- Interventional Cardiology
- Public Health
Background:
- The Hellenic Heart Registry on Percutaneous Coronary Interventions (HHR-PCI) was a prospective, observational study.
- It collected data from January 2008 to October 2010.
- Patients included those with stable angina or acute coronary syndromes undergoing PCI.
Purpose of the Study:
- To establish the first web-based national registry for percutaneous coronary intervention (PCI) in Greece.
- To gather data on patient demographics, procedural characteristics, and in-hospital outcomes.
- To provide insights into the practice of interventional cardiology in Greece.
Main Methods:
- Utilized a secure web-based interface for data entry from participating PCI centers.
- Collected data on indications, demographics, procedural characteristics, and in-hospital outcomes.
- Geographically divided participating centers into three main regions: Athens, Thessaloniki, and Rest of Greece.
Main Results:
- Eighteen centers participated, entering data for 3441 patients.
- PCI was elective in 47.1% and for acute coronary syndrome in 52.5%.
- Drug-eluting stents were used in 74.2% of lesions; in-hospital adverse events were low (death 0.5%, MI 1%, CVA 0.6%).
Conclusions:
- HHR-PCI was the first national web-based PCI registry in Greece.
- It offered valuable insights into interventional cardiology practices and outcomes.
- Maintaining and extending such registries is crucial for improving quality and outcomes research.
Introduction:
The Hellenic Heart Registry on Percutaneous Coronary Interventions (HHR-PCI) was a prospective, observational registry of patients with stable angina or acute coronary syndromes who underwent percutaneous coronary intervention (PCI) between January 2008 and October 2010.
Methods:
HHR-PCI was a database that used a secure web-based interface for data entry by individual users. All PCI centers and operators were invited to participate. The participating PCI centers were geographically divided into three main regions: Athens Metro Area, Thessaloniki Metro Area, and Rest of Greece. Indications, demographics, procedural characteristics, and in-hospital outcomes (death, myocardial infarction, cerebrovascular accidents) were recorded.
Results:
Eighteen (18) centers participated in the registry (2008-2010) in a systematic fashion, entering complete data for 3441 patients (males 83.1%, mean age 64.1 years, 5521 lesions). PCI was elective in 47.1% of patients and was used to treat an acute coronary syndrome in 52.5%. There were 742 (21.6%) patients treated for ST-segment elevation myocardial infarction, with 225 (30.3%) receiving primary PCI (mean door-to-balloon time 140 minutes). The mean numbers of stents per lesion and per patient were 1.14 and 1.74, respectively, with drug eluting stents being used in 74.2% of coronary lesions. Periprocedural complications were observed in 105 patients (3.1%), while the incidence of in-hospital death, myocardial infarction, and cerebrovascular event were 0.5%, 1%, and 0.6%, respectively.
Conclusions:
HHR-PCI was the first web-based national PCI registry in Greece and has provided useful insights regarding the practice of interventional cardiology in this country. Efforts should be made to maintain and extend this type of PCI registry, with a view to improving quality and outcomes research in the field of interventional cardiology.
