Introduction: bifurcation lesions, as a manifestation of coronary atherosclerosis, represent one of the greatest challenges in percutaneous coronary intervention.
Objectives: to characterize the outcomes of percutaneous coronary intervention in patients with bifurcation lesions treated at the Hermanos Ameijeiras Clinical Surgical Hospital between January 2016 and December 2017.
Methods: a prospective, longitudinal observational study was conducted in a series of patients diagnosed with coronary artery disease involving bifurcation lesions treated with percutaneous coronary intervention. A probabilistic simple random sampling was performed, selecting 143 patients. Data were obtained through document review, and descriptive and inferential statistical methods were applied.
Results: the mean age was 61.9 years, with a predominance of men (78.3%) and hypertensive patients (81.1%). Lesions were mostly longer than 20 mm (76.2%), severely calcified (72.7%), thrombotic (45.5%), located in the anterior descending–diagonal bifurcation (57.3%), and classified as Medina 1-1-0 (40.6%). The simple strategy was predominantly used (88.2%), with drug-eluting stents implanted in 55.2%. During follow-up, the most frequent adverse events were stent thrombosis (4.8%), restenosis (4.1%), and cardiac death (3.4%), with no statistically significant associations identified due to the low number of complications.
Conclusions: patients with cardiovascular risk factors and stable ischemic heart disease predominated among those treated with percutaneous coronary intervention, with stent thrombosis and restenosis being the most frequent adverse events.
