Summary: | The value of biomarkers of myocardial damage or inflammation in off-pump coronary artery bypass (OPCAB) surgery has not yet been established. In a prospective study of 51 consecutive patients scheduled for elective OPCAB surgery, preoperative levels of troponin T, C-reactive protein, interleukin-6, and tumor necrosis factor α were determined. The primary endpoint was the combination of cardiac death or acute myocardial infarction (AMI) within 30 days. Seven patients (14%) presented with an adverse event: 3 cardiac deaths and 6 AMIs. Univariate analysis identified the following adverse event predictors: renal failure (50% vs 11%;
P=.028), left ventricular ejection fraction 0.10 ng/dL (43% vs 9%,
P=.016), and EuroSCORE rating (7.6 [2.5] VS. 5.2 [2.6];
P=.031). A preoperative troponin-T level >0.10 ng/dL (
P=.03) was the only independent adverse event predictor. No significant differences were found with biomarkers of inflammation (P>.05). The presence of a preoperative troponin-T level >0.10 ng/dL is associated with a higher risk of cardiac death or AMI in patients undergoing OPCAB surgery.
El papel de los marcadores de daño miocárdico e inflamación en la cirugía de revascularización coronaria (CRC) sin circulación extracorpórea (CEC) no ha sido establecido. Se realizó un estudio prospectivo de 51 pacientes consecutivos que recibieron CRC sin CEC. Se determinaron las concentraciones preoperatorias de troponina T, proteína C reactiva, interleucina-6 y factor de necrosis tumoral alfa. El evento primario fue el combinado de muerte cardiaca o infarto agudo de miocardio (IAM) a los 30 días. Un total de 7 pacientes (14%) presentaron eventos (3, muerte cardiaca y 6, IAM). En el análisis univaria-ble fueron predictores la insuficiencia renal (el 50 frente al 11%; p = 0,028), la fracción de eyección del ventrículo izquierdo < 50% (el 38 frente al 9%; p = 0,033), la troponina T > 0,10 ng/dl (el 43 frente al 9%; p = 0,016) y el EuroSCORE (7,6 ± 2,5 frente a 5,2 ± 2,6; p = 0,031). La troponina T > 0,10 ng/dl preoperatoria fue el único predictor independiente de eventos (p = 0,03). Los marcadores de inflamación no mostraron diferencias (p > 0,05). La presencia de troponina T preoperatoria > 0,10 ng/dl se asocia con un mayor riesgo de muerte o IAM en pacientes que reciben CRC sin CEC. |
