Older adults with serious mental illness have a high prevalence of coronary artery disease and of its major risk factors, that is, arterial hypertension, dyslipidemia, and diabetes mellitus. The prevalence and clinical control of these conditions have not been compared in geropsychiatric inpatients with dementia versus those with mood or psychotic disorders.

What is the prevalence and acuity of coronary artery disease, arterial hypertension, dyslipidemia, and diabetes mellitus among patients with dementia, mood, and psychotic disorders admitted for geropsychiatric care?

Patients 65 years of age or older were identified in a cohort of 1000 patients consecutively admitted over a 3-year period to the geropsychiatric unit of a 200-bed mental health hospital in suburban New York. All patients had a structured clinical and laboratory evaluation within 72 hours of admission.

Primary psychiatric diagnoses, medical history, the frequency of poorly controlled cardiometabolic comorbidity requiring an immediate change in the management plan, and the Charlson Comorbidity Index (CCI).

The 65 years and older patient sample (N = 689) had a mean age of 74.8 years, and 58.8% of the subjects were women. The 205 patients with dementia were older (P < 0.001) than the 337 patients with mood disorders and the 147 patients with psychotic syndromes. The numbers of medical conditions and the CCI after exclusion of dementia were similar in patients with dementia versus patients without dementia. A substantial number of patients had poorly controlled arterial hypertension (51.2%), dyslipidemia (25.4%), diabetes (24.2%), and coronary artery disease (15.4%). Patients with dementia had a lower prevalence of poorly controlled dyslipidemia (P = 0.0006), diabetes (P = 0.0089), and coronary artery disease (P = 0.045).

Compared with mood or psychotic disorder, a diagnosis of dementia with behavioral disturbance seemed to be associated with better control of coronary artery disease, dyslipidemia, and diabetes mellitus in geropsychiatric inpatients.
