Las oclusiones coronarias crónicas se asocian con un impacto negativo en el pronóstico a largo plazo. Objetivos: Conocer si existe diferencia en los eventos cardiovasculares mayores en pacientes sometidos a revascularización exitosa vs revascularización fallida de lesiones de oclusión total crónica en angina estable. Material y métodos: Estudio correlacional, transversal, con dos grupos independientes. Resultados: Se evaluaron 71 pacientes, en un contexto de angina crónica estable, en la Unidad Médica de Alta Especialidad del Bajío, del periodo de enero de 2013 a febrero de 2020, se obtuvieron 41 pacientes con revascularización exitosa (RE) y 30 con revascularización fallida (RF). La tasa de éxito de revascularización fue de 57.7%. La tasa de eventos cardiovasculares mayores encontrados entre pacientes con RE vs RF en este estudio fueron: eventos de angina inestable postrevascularización en 12.5% del grupo RE y en 13.3% del grupo RF (p = 0.918). El grupo de revascularización exitosa tuvo ausencia de infartos agudos al miocardio y en 3.3% del grupo RF (p = 0.245) sí hubo. Ocurrió muerte de origen cardiaco en 0% del grupo RE y en 3.3% del grupo RF (p = 0.245). Mientras que tuvieron necesidad de nueva vascularización el 0% del grupo RE y el 6.7% de los pacientes del grupo RF. La tasa de supervivencia de pacientes con RF fue de 96.7% y en pacientes con RE fue de 100%. Conclusiones: La revascularización exitosa vs fallida no demostró diferencias estadísticamente significativas en la tasa de eventos cardiovasculares mayores aBSTRaCT Introduction: Chronic coronary occlusions are associated with a negative impact on long-term prognosis. Objectives: To know if there is a difference in major cardiovascular events in patients undergoing successful revascularization versus failed revascularization of chronic total occlusion lesions instable angina. Material and methods: Cross-sectional, correlational study with two independent groups. Results: 71 patients were evaluated, in a context of stable chronic angina, in the High Specialty Medical Unit of Bajio, from January 2013 to February 2020; 41 patients with successful revascularization (RE) and 30 with revascularization was failed (RF). The revascularization success rate was 57.7%. The rate of major cardiovascular events found among patients with RE vs RF in this study were: unstable angina events post-revascularization in 12.5% of the RE group and in 13.3% of the RF group (p = 0.918). AMI (acute myocardial infarction) occurred in 0% of the RE group and in 3.3% of the RF group (p = 0.245). Death of cardiac origin occurred in 0% of the RE group and in 3.3% of the RF group (p = 0.245). In contrast 0% of the RE group and 6.7% of the RF group patients needed new vascularization. The survival rate in RF patients was 96.7%, and in RE patients, it was 100%. Conclusions: Successful versus failed revascularization did not show statistically significant differences in the rate of major cardiovascular events.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
