    We studied 34 patients, from july 1 to august 31, 2014 at Ameijeiras hospital. A cardiac surgery were performed in all of them, 18 with coronary disease and 16 with valvular disease (10 aortic and 6 mitral) this work was approved by the Ethics Committee responsible for this investigation. We determined they serological status in relation with cytomegalovirus (CMV) and herpes simple virus (HSV) before cardiac surgery and we used samples of tissues during surgery (Left Internal mammary artery, 18.Right Internal mammary artery, 1. Ascending Aortic wall 9, Valvular tissues, 16) to find DNA of cytomegalovirus, herpes simple virus and Clamidophila pneumonia with PCR. The most frecuent risk factor was smoking habit (64,7%), represent 61,1% in coronary disease group and 68,7% in valvulvar. Hypertension was the second one risk factor (58,8%), particulary elevated in coronary disease group(66,6%). The patients in coronary group positive IgG against CMV represent the 77, 7% and with IgG against HSV 66,6%. In the valvular group positive IgG against CMV represent the 68, 7% and with IgG against HSV 56,25%. No one sample of tissue showed genomic presence of C. pneumoniae, CMV or HSV with PCR.

Objetivo: Identificar la relaci贸n entre la infecci贸n por el Citomegalovirus, el Virus Herpes Simple y la Clamydophila聽 pneumoniae聽聽 y su posible protagonismo en la aterosclerosis en pacientes operados de cirug铆a cardiaca. M茅todos: Se estudiaron 34 pacientes que requirieron una intervenci贸n cardiaca, 18 con enfermedad coronaria y聽 16 con enfermedad valvular, los que dieron su consentimiento a participar en el estudio, se determin贸 su estado serol贸gico con respecto a Citomegalovirus y virus del herpes simple previo al acto quir煤rgico. Se les extrajeron muestras de tejido y se les realiz贸 determinaci贸n de ADN de Citomegalovirus(CMV), Virus Herpes Simple(VHS)聽 y Clamidophila pneumoniae. Resultados: El h谩bito de fumar fue el factor de riesgo m谩s frecuente (64,7%), seguida en orden de frecuencia por Hipertensi贸n Arterial (58,8%), la cual fue particularmente frecuente para el grupo coronario (66,6%)..Los pacientes coronarios con IgG anti CMV representan el 77,7% y con IgG anti VHS el 66,6%. De igual forma los valvulares con IgG anti CMV representan el 68,7% y con IgG anti VHS el 56,25%. En ninguna muestra de tejido se demostr贸 la presencia del genoma de estos agentes. Conclusiones: Se demuestra la asociaci贸n entre factores de riesgo conocidos en聽 pacientes con cardiopat铆a isqu茅mica, existe elevada prevalencia serol贸gica de exposici贸n a los agentes infecciosos estudiados pero no se demuestra su presencia en los tejidos estudiados.Palabras clave:Cirug铆a Cardiaca, aterosclerosis,聽 infecci贸n.聽Abstract We studied 34 patients, from july 1 to august 31, 2014 at Ameijeiras hospital.
