Article information
La proteína C-reactiva (PCR), un marcador sensible de inflamación, es un predictor independiente de enfermedad cardiovascular futura (ECV), que es una de las principales causas de muerte en todo el mundo. El papel de la inflamación en esta entidad ha sido bien documentado en la última década, y se ha demostrado inflamación en todas las fases de la aterosclerosis, desde el inicio y el crecimiento, hasta la ruptura de la placa. La PCR es una proteína de fase aguda, altamente sensible como marcador de inflamación general. En estudios experimentales, se ha determinado la presencia de PCR en arterias que presentan lesiones ateroscleróticas. También se ha demostrado que, en forma directa, la PCR induce la producción de otras células inflamatorias y que disminuye la expresión de la óxido nítrico sintetasa. Es decir, desde el punto de vista biológico, la PCR participa en el proceso aterogénico. En adultos, la PCR, detectada con técnicas ultrasensibles (PCRus), se asocia con los factores de riesgo tradicionales y su concentración predice eventos cardiovasculares.

C-reactive protein (CRP), a sensitive marker of inflammation is an independent predictor of future cardiovascular disease (CVD), which is one of the main causes of death worldwide. The role of inflammation in cardiovascular disease has been well documented in the last decade, and inflammation has been demonstrated in all stages of atherosclerosis, from its beginning and growth to the plaque rupture. CRP is an acute phase protein, highly sensitive as a marker of general inflammation. The presence of CRP has been determined in experimental studies in arteries with atherosclerotic lesions. It has been demonstrated as well that CRP induces directly the production of other inflammatory cells and decreases the expression of nitric oxide synthase. This means that from the biological standpoint CRP takes part in the atherogenic process. In adults, CRP detected through high sensitive CRP-test (hs-CRP) is associated to traditional risk factors and its concentration predicts cardiovascular events.
