Study on the Use of Elective Angioplasty for Chronic Coronary Syndromes at a Cardiology Hospital

What this Trial Is About

Researchers are evaluating how appropriate elective percutaneous coronary intervention PCI, a procedure to open blocked heart arteries, is for patients with chronic coronary syndrome CCS who have symptoms not relieved by optimized medical treatment. This observational study focuses on measuring how often PCI is classified as appropriate, possibly appropriate, or rarely appropriate based on established criteria updated by the American College of Cardiology Foundation. The study addresses the gap in data about PCI use in Brazil compared to established studies in the United States and Japan. The study analyzes approximately 2,500 consecutive elective PCI procedures performed between 2017 and 2020 at a cardiology reference university hospital in Brazil. The PCI procedure is minimally invasive and is performed in patients with CCS symptoms under non-acute conditions after evaluation by a Heart Team. This study does not involve treatment assignment but observes clinical practice and PCI indication appropriateness. Participants are patients who underwent elective PCI, with data collected immediately after the procedure to classify PCI appropriateness. Researchers will also monitor outcomes such as mortality, non-fatal cardiovascular events, recurrent angina, and heart failure up to 12 months after the procedure. The study aims to provide insights into the quality of cardiovascular care and guide future treatment decisions for CCS patients in Brazil.
