ABSTRACT
Introduction: In this study, we analyzed the prognostic impact of mild cognitive impairment (MCI) prior to cardiac surgery on 12-month clinical outcomes in older patients. Method: We performed a longitudinal prospective study of 48 patients undergoing cardiac surgery and 26 neurologically healthy participants aged 65 years or older. All participants underwent a neuropsychological assessment. Functional status, quality of life and frailty were assessed in candidates for surgery. One year after surgery, 24 patients remained in the study. Results: Mild cognitive impairment (MCI) was diagnosed in 35% of the patients at baseline. Postsurgical changes in functionality consisted of a tendency toward impaired basic activities of daily living (BADL) in the MCI group and a statistically significant worsening in instrumental activities of daily living (IADL) in women with MCI. Changes in quality of life consisted of a significant improvement in anxiety-depression in the MCI group and a tendency toward greater pain-discomfort in the non-MCI group. Cognitive status significantly declined only in the non-MCI group. Neither group showed significant changes in frailty. Relative risk analysis showed that patients with a diagnosis of MCI at baseline had a higher risk of cognitive decline at follow-up, while those without a diagnosis of MCI at baseline had a lower risk of impaired IADL. No association was found between MCI and resource use. Preoperative impairment in memory, visuospatial and executive functions was significantly associated with loss of quality of life at follow-up. Impairment of memory and visuospatial function was significantly associated with cognitive decline. Preserved memory was associated with a lower risk of impaired BADL at follow-up. Conclusion: The present study provides clue on the impact of MCI in candidates for cardiac surgery. Preoperative detection of cognitive impairment could be highly valuable to help guide pre- and post-operative management.
ABSTRACT
Cardiovascular risk factors (CVRF) are very prevalent in the elderly population and in addition to predisposing to cardiovascular disease they are related to functional decline, which limits the quality of life in this population. The objective of this work is to offer a review of the current evidence in the management of CVRF in the elderly population. The search strategy was executed in PubMed, Clinicalstrials.org and Embase, to search for clinical trials, observational cohort or cross-sectional studies, reviews, and clinical practice guidelines focused or including elderly population. The results provided were refined after reading the title and abstract, as well as elimination of duplicates, and were finally identified and assessed following the GRADE methodology. A total of 136 studies were obtained for all predefined risk factors, such as sedentary lifestyle, smoking, obesity and metabolic syndrome, hypertension, diabetes mellitus, dyslipidemia and alcohol. We described the results of the studies identified and assessed according to their methodological quality in different recommendation sections: diagnostic and prevention, intervention, or treatment in the elderly population. As the main limitation to the results of this review, there is the lack of quality studies whose target population is elderly patients. This issue limits the recommendations that can be made in this population. Due to this reason, comprehensive geriatric assessment seems the best tool currently available to implement the most appropriate treatment plans based on the baseline situation and comorbidity of each elderly patient.
