Relationships between cerebral infarction and carotid artery atheroclerosis plaques and plasma fibrinogen level in aging patients

Objective To explore the relationships between cerebral infarction and carotid artery atherosclerosis plaque and plasma fibrinogen level in aged patients.Methods 64 aged patients with cerebral infarction and 40 control people without cerebral infarction were examined with Color Doppler Ultrasound in the carotid artery,meanwhile their plasma fibrinogen contents were detected.Results The carotid artery atherosclerosis plaques were found in 56 of 64 cerebral infarction patients(87.5%),and only in 6 of 40 control people(15.0%).The probability of carotid artery atherosclerosis plaque in the cerebral infarction group was signifancantly higher than that in the control group(P0.001).Compared with the control group,the soft carotid artery atheroclerosis plaque was much more fonud in the cerebral infarction group(P0.01),and the plasma fibrinogen level was also higher in the cerebral infarction group than that in control group(P0.05).Conclusions Cerebral infarction is highly related to carotid artery atherosclerosis plaque,plasma fibrinogen may play an important role in the formation and development of carotid artery atherosclerosis plaque.
