Clever, that.

Dementia May Spur Pacemaker-Implant Recommendations

Subjects with dementia at the baseline visit (the visit prior to their assessment for a new pacemaker implant) were 60% more likely (p=0.02) to get a device than those initially without cognitive impairment.
The analysis adjusted for demographics, intensity of pacemaker use in each center's referral region, functional status, cardiac comorbidity status, hypertension, and Hachinski Ischemic Score (used to differentiate ischemic from degenerative forms of dementia).

Ssshhh!  The patients never noticed!
