Insights
Percutaneous coronary intervention (PCI) at Thammasat University Hospital demonstrated a high success rate of 95.57% with low in-hospital adverse events. This early experience highlights the safety and effectiveness of PCI in managing coronary artery disease.
Area of Science:
- Cardiology
- Interventional Cardiology
- Public Health
Background:
- Percutaneous coronary intervention (PCI) is a key revascularization strategy for coronary artery disease.
- Establishing early outcomes is crucial for developing new interventional cardiology programs.
Purpose of the Study:
- To evaluate the initial results and in-hospital outcomes of percutaneous coronary intervention (PCI) procedures.
- To assess the safety and efficacy of a newly established cardiac catheterization laboratory.
Main Methods:
- Prospective, single-center study including 617 patients undergoing 755 PCI procedures.
- Data collection encompassed clinical characteristics, angiographic findings, and in-hospital adverse events.
- Analysis focused on success rates and major adverse cardiac and cerebrovascular events (MACCE).
Main Results:
- The overall angiographic success rate for PCI was 95.57%.
- Major adverse events included death (0.93%), periprocedural myocardial infarction (3.17%), emergency coronary artery bypass graft (0.53%), and stroke (0.26%).
- Indications for PCI included non-ST segment-elevation acute coronary syndrome (41.72%) and chronic stable angina (25.32%).
Conclusions:
- The initial three years of PCI experience at Thammasat University Hospital show high procedural success.
- In-hospital adverse outcomes were low, indicating a safe and effective early program.
- These findings support the integration of PCI services in developing healthcare settings.
Objective:
To study the results of percutaneous coronary intervention (PCI) and in-hospital outcomes in cardiac catheterization laboratory, Thammasat University Hospital since May, 2006 until April, 2009.
Material And Method:
This is the prospective, single-center study. The consecutive patients who underwent PCI in Thammasat University Hospital since May 2006 to April 2009 were recruited in the study. Clinical data, angiographic data, and in-hospital outcomes were analyzed and demonstrated.
Results:
Six hundred and seventeen patients undergoing 755 PCI procedures were enrolled in the study. 62.70% were male and 37.30% were female. Mean age was 65.45 +/- 11.21 years (range 33-97 years) and 20.10% were more than 75 years old. The indications for PCI were non-ST segment-elevation acute coronary syndrome (NSTEACS) (41.72%), chronic stable angina (25.32%), acute ST segment elevation myocardial infarction (STEMI) (8.87%), staged PCI (15.76%). The other indications were heart failure, cardiomyopathy, post-cardiac arrest and etc. The procedure was single vessel PCI in 73.25% and multivessel PCI in 26.75% (double vessels PCI 24.64% and triple vessels PCI 2.11%). According to lesion locations, 45.21% were left anterior descending (LAD) artery lesions, 30.09% were right coronary artery (RCA) lesions, 23.28% were left circumflex (LCX) artery lesions, 1.19% were left main (LM) lesions and 0.24% were graft lesions. The overall angiographic success rate was 95.57%. During hospital stay the major adverse events developed as death in 0.93%, periprocedural myocardial infarction in 3.17%, emergency coronary artery bypass graft in 0.53%, and stroke in 0.26%.
Conclusion:
During the first three years of PCI experience in Thammasat University Hospital, the overall success rate was high with low in-hospital adverse outcomes.
