Purpose
The purpose of the study is to study if coronary angiography cause cognitive dysfunction.
| Condition | Intervention |
|---|---|
| Coronary Heart Disease Heart Valve Diseases | Procedure: Arterial approach |
| Study Type: | Observational |
| Study Design: | Observational Model: Case-Only Time Perspective: Prospective |
| Official Title: | Study of Cognitive Function Before and After Coronary Angiography |
Further study details as provided by Per Tornvall, Karolinska Institutet:
Primary Outcome Measures:
- Change in cognitive dysfunction from baseline to two days after coronary angiography [ Time Frame: Baseline and two days ]The Montreal Cognitive Assesment test will be performed before, 2 and 30 days after coronary angiography
Secondary Outcome Measures:
- Number of patients with cerebral microemboli [ Time Frame: Baseline ]Cerebral microembolism will be studied by transcraniell doppler at the time of angiography. Findings will be related to change in cognitive function between baseline and two days.

Coronary angiography

Procedure: Arterial approach
Randomization to right radial or femoral approach
Other Name: Coronary arteriography
|
Detailed Description:
We have previously shown, using transcranial doppler, that coronary angiography cause cerebral microembolism. Cerebral microemboli were more common using the radial than femoral approach. Previously, cerebral microembolism has been associated with new cerebral lesions on MRI. The clinical significance of these new lesions is not determined. The primary aim of this pilot study is to see if coronary angiography cause cognitive dysfunction determined by the MoCA-test. A secondary aim is to relate cognitive dysfunction to cerebral microembolism measured by transcranial doppler. A third aim is to study potential differences between the femoral and radial approaches.
