ANAHEIM, CALIF. – Across the spectrum of cardiovascular disease, the more comorbid conditions a patient has, the higher the likelihood of mild cognitive impairment, Jocasta Ball, PhD, reported at the American Heart Association scientific sessions.
Indeed, her cross-sectional analysis of baseline data on 2,161 participants in five randomized controlled trials of nurse-led chronic disease management in cardiovascular disease (CVD) showed that for every 1-unit increase in the age-adjusted Charlson Comorbidity Index, the likelihood of mild cognitive impairment (MCI) jumped by 19%.
This novel observation has important clinical implications: “MCI is becoming increasingly recognized as exerting a powerful and negative impact on the risk, management, and prognosis of CVD patients,” explained Dr. Ball of the Baker Heart and Diabetes Institute in Melbourne. “Because MCI undermines a patient’s ability to comply with medical treatment and adds to patient complexity, it is critical [to identify] higher-risk individuals who require closer surveillance and improved early intervention.”
She added that the findings open up a whole new field of research aimed at developing new interventions to help patients with CVD and MCI stay on track with their heart disease treatment program.
The 2,161 subjects, mean age 70 years and two-thirds male, ranged across the full spectrum of cardiovascular disease, from mild to severe. All were screened for MCI by completing the Montreal Cognitive Assessment, or MoCA. A MoCA score below 26 out of a possible 30 is defined as MCI.
Forty-seven percent of subjects had MCI. They were older, with a mean age of 73 years versus 67 years; were more likely to have a history of stroke, by a margin of 20% versus 12%; had a 52% prevalence of atrial fibrillation versus 44%; and had a 50% prevalence of heart failure versus 39% in subjects with normal cognition. In addition, 48% of the MCI group screened positive for depressive symptoms versus 37% of those without MCI, and 28% of patients with MCI had type 2 diabetes, compared with 22% of those without MCI. Renal disease was also significantly more prevalent in the MCI group, by a margin of 21% versus 14%.
In a multivariate regression analysis, the strongest predictors of MCI in patients across the spectrum of CVD were current smoking, with a 2.5-fold increased risk compared with that of nonsmokers, and atrial fibrillation, with a 1.3-fold increased risk.
Dr. Ball reported having no financial conflicts regarding her study.

REPORTING FROM THE AHA SCIENTIFIC SESSIONS
Key clinical point: The more comorbid conditions a patient with cardiovascular disease has, the greater the likelihood of mild cognitive impairment becomes.
Major finding: For each 1-unit increase in the Charlson Comorbidity Index, the likelihood of prevalent mild cognitive impairment rose by 19%.
Study details: This cross-sectional study assessed the association between mild cognitive impairment and Charlson Comorbidity Index score in 2,161 patients with cardiovascular disease of varied degrees of severity.
Disclosures: The presenter reported having no financial conflicts regarding her study.
