Note. CES–D = Center for Epidemiological Studies–Depression Scale; DEX = Dysexecutive Questionnaire; LM I = Logical Memory Immediate Recall; LM II = Logical Memory Delayed Recall; LVEF = left ventricular ejection fraction; M = mean; MMSE = Mini-Mental State Examination; SD = standard deviation; WTAR = Weschler Test of Adult Reading. Data presented for WTAR, LM I and II, Letter and Category Fluency, Digit Span, and Digit Symbol are age-scaled standardized scores. Data presented for DEX, CES–D, and MMSE are raw total scores.
