  Purpose
The investigators will evaluate the determinants of cerebral impairment in patients with non-ischemic heart failure compared to controls, and its relation to cognitive function. They hypothesize that patients with heart failure have impaired brain perfusion and hemodynamic factors are associated with cognitive dysfunction.

Condition
Heart Failure Dilated Cardiomyopathy Perfusion Cognitive Impairment Cerebral Hypoperfusion

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Cross-Sectional

Primary Outcome Measures:
  • Determinants of cerebral impairment [ Time Frame: Baseline ]
    Determinants of cerebral impairment in patients with heart failure compared to controls, where cerebral impairment is defined as decreased cognitive function and cerebral hypoperfusion


Secondary Outcome Measures:
  • Prevalence of cognitive impairment [ Time Frame: Baseline ]
    Prevalence of cognitive impairment in patients with heart failure

  • Relation of cognitive impairment with local perfusion [ Time Frame: Baseline ]
    Relation of cognitive impairment with perfusion of carotid artery territory and basilar artery territory

  • Relation of cognitive impairment with the severity of heart failure [ Time Frame: Baseline ]
    Relation of cognitive impairment with the severity of heart failure

  • Relation of cognitive impairment with cardiac output [ Time Frame: Baseline ]
    Relation of cognitive impairment with cardiac output

  • Relation of cognitive impairment with the severity of congestion [ Time Frame: Baseline ]
    Relation of cognitive impairment with the severity of congestion

  • Relation of cognitive impairment with the decrease in cerebral perfusion [ Time Frame: Baseline ]
    Relation of cognitive impairment with the decrease in cerebral perfusion

  • The difference of cognitive domains in above relations [ Time Frame: Baseline ]
    The difference of cognitive domains in above relations
