    Abstract: B: Hypertension affects the target-organs diversely. Most evidence on target-organ damage in hypertension is related to kidney and heart. The cerebrovascular and cognitive impairment are less studied. O: To study the cognitive function changes in patients with hypertension on different stages compared to the control pairs and their correlation with the arterial stiffness properties assessed by non-invasive methods and cerebral circulation assessed by transcranial Doppler. M: In a cross sectional study 162 patients (42 controls and 120 hypertensive) were comparatively evaluated. Hypertensive patients were divided in three stages according to the blood pressure levels or medication use (HTN-1: BP 140-159/90-99 or use of one antihypertensive drug; HTN-2: BP 160-179/100-109 or use of two drugs and HTN-3: BP ≥180/110 or use of three or more drugs). The following variables were evaluated: pulse wave velocity, intima medial thickness, cerebral blood flow velocities by transcranial Doppler (TD) and cognitive function. Mean velocity of middle cerebral artery was continuously monitored at resting and during the breath holding test (30 seconds) and 3 minutes handgrip maneuver. Cognitive function was assessed by mini mental state examination and Montreal Cognitive Assessment. R: Compared to control group, HTN-3 group was older, had higher BMI, IMT and PWV and lower educational level and family income (Table 1). Interestingly, the higher the hypertension stage the poorer was the performance in cognitive tests even after age correction. There was no difference among the groups related to TD velocities at rest and the hand-grip maneuver. However, it was noted a lower breath holding index in the hypertensive group (HTN-1=0.94±0.56; HTN-3=0.97±0.59 vs Control=1.5±0.68; p=0.002) which could infer less vasomotor reactivity in these patients. C: Cognitive impairment was more frequent in patients with hypertension and this frequency was related to hypertension severity.

    Abstract P519: Arterial Stiffness is Associated With Lower Performance on the Cognitive Tests at Different Domains in Hypertensive Patients

    Abstract: Background: Cognitive impairment and elevated arterial stiffness are described in patients with arterial hypertension(AH), but its correlations are not well studied. Objectives: To study the cognitive function at different domains and arterial properties in patients with AH stage 1 to 3 compared to normotensives and to evaluate the correlations between these variables. Methods: We evaluated 221 subjects, 71 normotensives (52±14yrs,47%male,65%white) and 150 patients with stage 1-3 AH (52±12yrs,45%male,70%white) under treatment. The global cognitive function was assessed by Mini Mental State Examination(MMSE) and Montreal Cognitive Assessment(MoCA). There was done a validated comprehensive battery of neuropsychological tests(NPE) assessed the following main cognitive areas: memory, language, visuospatial ability, executive function, attention. Pulse wave velocity(PWV) was measured by Complior® device. Carotid properties were assessed by radiofrequency ultrasound(WTS®). Central arterial pressure and augmentation index (AIx) were obtained using applanation tonometry(Sphygmocor®). Results: Mean BP of the normotensive group (122.1±8/76.7±7mmHg) was significantly lower than hypertensive patients (135.2±13/83.3±10 and 149.9±29/91.5±16mmHg). Severe HTN group had worse performance in cognitive evaluation either by MMSE (26.8±2.1 vs 27.4±2.1 vs. 28.0±2.0, p=0.004) or MoCA test (23.4±3.7 vs. 24.9±2.8 vs. 25.5±3.2, p 〈 0.001). On the neuropsychological tests hypertensive patients had worse performance mainly in visuoperceptual and visuospatial capacities and executive function. On the multivariate regression analysis, the following independent associations were observed: Aix-language, executive function, visuospatial and attention; cSBP-MoCA; IMT-memory and attention; PWV-memory, executive function, visuospatial and attention. Higher PWV group had more cognitive dysfunction. Conclusions: Cognitive impairment at different domains was more frequent in patients with different stages of AH. Arterial functional and structural properties were diversely associated with cognitive performance at different domains
