VASCULAR RISK FACTORS AND COGNITIVE FUNCTIONS IN THE PATIENTS WITH CEREBROVASCULAR DISEASE

The aim: To assess the severity of cognitive impairment (CI) in patients with cerebrovascular disease (CVD) depending on the number of vascular risk factors (VRF). Materials and methods: The study consisted of five hundred and eighty patients with CVD (247 females and 333 males) aged from 45 to 89 years (mean age: 64,1±8,9 years). The patients were divided into 6 groups (I, II, III, IV, V, VI) depending on the number of VRF. The examination consisted of a standard clinical evaluation, neurological examination, the application of neuropsychological tests (the MMSE; the PALT/The Paired Associates Learning Test; clock drawing test), laboratory tests, MRI of brain. Results: According to ANOVA, the greater the number of VRF the patients had, the lower was their total MMSE score corresponding to more pronounced cognitive decline (F=2,97, p=0,012). A significant negative correlation between patients’ age and their MMSE score was detected regardless of their VRF count. The patients of the V and VI groups had substantially lower parameters of immediate, delayed memory and clock drawing test score comparing to the patients of the I group. Conclusions: The presence of 4 and more VRF was related to more pronounced CI in the patients with CVD. Decline of different aspects of memory, attention, spatial orientation, abstract thinking, planning, concentration, executive and visuospatial skills in groups of patients with 4,5 and 6 vascular risk factors was established. Age was substantially associated with cognitive decline in all the group of patients.

And Function

Throughout the lifespan, common variations in systemic health and illness contribute to alterations in vasculature structure and function throughout the body, significantly increasing risk for cardiovascular and cerebrovascular disease (CVD). CVD is a prevalent cause of mortality in late life; it also promotes brain alterations, contributing to cognitive decline and, when severe, vascular dementia. Even prior to diseased states, individual variation in CVD risk is associated with structural and functional brain alterations. Yet, how cumulative asymptomatic alterations in vessel structure and function contribute to more subtle changes in brain tissue integrity and function that emerge in late life is unclear. Finally, vascular risk factors are associated with the clinical progression of neurodegenerative diseases such as Alzheimer’s disease (AD); however, recent theory posits that vascular degeneration may serve a contributory role in these conditions. This chapter reviews how lifespan changes in vascular health contribute to degenerative changes in neural tissue and the subsequent development of cognitive impairment and/or vascular dementia. It first discusses associations between vascular risk factors and cognition and also how declining vascular health may lead to cognitive impairment and dementia. Next, it identifies basic aspects of cerebrovascular anatomy and physiology sustaining tissue health and discusses how vulnerabilities of this system contribute to neurodegenerative changes. Finally, it reviews evidence of vascular contributions to AD and presents ideas for future research to better understand the full spectrum of cerebrovascular contributions to brain aging, cognitive decline, and dementia.

Atherothrombotic Disease

Background and Purpose: The objective of this study were to describe the proportion of patients eligible for the COMPASS trial among stable outpatients with either established atherothrombotic disease or major vascular risk factors, and to analyze 6-month incident stroke risk according vascular risk factors at baseline. Methods: We prospectively recruited 5,101 stable outpatients in 172 sites, within the Mexican INDAGA cohort study. Inclusion criteria were age >18 years and established atherothrombotic disease [history of either acute coronary syndromes (ACS), acute ischemic stroke (AIS)/transient ischemic attack (TIA) or peripheral artery disease (PAD)] or major vascular risk factors (age <55 years plus ≥2 major vascular risk factors, or age ≥55 years plus ≥1 vascular risk factors). Among these patients, we applied the selection criteria of the COMPASS trial for analysis, dividing the population in no COMPASS criteria met and COMPASS criteria met, and this last group subdivided among patients with previous AIS/TIA and without this antecedent, in order to stratify the risk for stroke during 6-month follow-up (incident AIS/TIA). Results: Among 5,101 stable outpatients with either established atherothrombotic disease (n=2,827) or major vascular risk factors (n=2,274), a total of 1,927 (37.8%) met COMPASS trial criteria: 1,054 (54.7%) with established cerebrovascular disease (past history of AIS/TIA) and 873 (45.3%) without. During 6-month follow-up, there were 89 incident AIS/TIA (39 AIS and 54 TIA): 1.7% among the whole population and 2.2% among the COMPASS subgroup. AIS/TIA occurred in a similar frequency among the COMPASS subgroup with established cerebrovascular disease (1.6%) and COMPASS without cerebrovascular disease (0.9%) (P=0.18). After a Cox-proportional hazards model, independent predictors of incident AIS/TIA were age ≥65 years (HR: 1.99, 95% CI: 1.29-3.07) and established cerebrovascular disease at baseline (HR: 1.61, 95% CI: 1.02-2.53). Conclusions: The majority of stable outpatients at vascular risk met COMPASS selection criteria and could be good candidates for low-dose rivaroxaban in addition to aspirin. Short-term predictors of AIS/TIA were old age and history of cerebrovascular disease
