Inflammatory Factors in Hypertensive Patients Complicated with Acute Myocardial Infarction

Objective To investigate the alteration and significance of inflammatory factors in hypertension patients complicated with acute myocardial infarction(AMI).Methods Eighty seven AMI patients were grouped as normotensive group(n=43) or hypertensive group(n=44),25 healthy subjects served as control.Plasma level of IL-1β,IL-6,IL-8,TNF-α and IFN-γ were determined at admission of hospitalization,24 h,48 h,5 d,7 d and 14 d after myocardial infarction using ELISA method.Results 1)Compared with the control group,the level of all inflammatory markers were elevated significantly in 2 weeks after myocardial infarction and showed a pattern of dynamic changes.2)Compared with normotensive group,IL-6 in hypertensive group was increased more significantly on 5th day(P=0.019) to 7th day(P=0.005)after AMI.Conclusion Inflammation was involved in the course of AMI since the early stage.Hypertension seems to exaggerated the inflammatory reaction after myocardial infarction.
