[Coronary artery disease multivessel not amenable to revascularization: contemporary cohort].

Abstract

Background: Severe diffuse coronary artery disease with anatomy that is not amenable to revascularization represents a poorly studied entity, with a poorly defined prognosis and prevalence, associated with high morbidity and mortality, poor quality of life and high hospitalization rates.

Objective: Due to the limited evidence in this clinical field and the absence of contemporary studies, we decided to explore this line of research, determining epidemiological, clinical and prognostic aspects.

Material and methods: Analytical, retrospective observational cohort study, carried out in a National Medical Center.

Results: The prevalence of three-vessel coronary artery disease not susceptible to revascularization was 12.2%, the majority were men (66%), over 65 years of age, with a high burden of comorbidities: pharmacological management consisted of beta blockers (91.5 %), antiplatelet aggregation (95.3%) and statins (95.3%): cardiovascular mortality was 9.4%, with myocardial infarction occurring in 10.4%: the predictor variables of mortality were chronic kidney disease, age over 70 years, insufficiency mitral valve.

Conclusion: Coronary artery disease of three vessels not susceptible to revascularization continues to be a frequent entity, with a high-risk clinical and anatomical profile, with a better contemporary prognosis despite the multiple gaps in knowledge that limit its understanding and treatment.
