[Assessment of the intima and media of carotid arteries in the course of hypertension in the elderly].

Unlabelled: According to the position of the European Society of Hypertension in 2009, the thickening of the inner and middle membrane complex of the carotid arteries (I-M CCA), or the finding of atherosclerotic plaques is associated with high cardiovascular risk. The increase in I-M CCA thickness, assessed within the carotid artery, is considered the initial stage of atherosclerosis. According to the concept of parallel development of atherosclerosis in many arterial areas I-M CCA is a recognized marker of the process involving other arteries, such as coronary arteries, kidney or lower limbs.

Aim: The aim of the study was evaluation of the intima and media of carotid arteries - I-M in the course of hypertension in the elderly.

Materials And Methods: The study involved 63 women and 17 men, aged from 75 to 93 years, who were diagnosed with arterial hypertension in accordance with the guidelines of the Polish Society of Hypertension. Patients were divided into two groups. The first pair consisted of a group of 1 hypertensive patients (HA) lasting up to 10 years of age over 85 years and a group of 2 patients with HA lasting up to 10 years at the age of 75-85 years. The second pair is group I - patients with HA over 10 years of age over 85 years and group II - patients with HA lasting over 10 years at the age of 75-85. Carotid artery examination was performed using the Aloka SSD-1100 ultrasound machine. The measurements were made within the left and right carotid wall of the common carotid artery in the anterior and lateral-posterior projection. The maximum thickness of the inner and middle membranes was measured in three places within two segments of the common carotid artery.

Results: It was observed that in the group of patients treated longer due to hypertension, the thickness of the intima-media complex is significantly higher than in patients with shorter duration. Moreover, in the examined group of patients in the analysis of individual correlations, life expectancy was influenced, among others, by significantly on the thickness of I-M CCA.

Conclusions: Both the older age of patients and the longer duration of hypertension caused thickening of the intima-media complex. The duration of hypertension greater than 10 years had a greater impact on the thickness of this complex than the age of the patients.
