Elevated IL-1 Beta Plasma Levels, Altered Platelet Activation and Cardiac Remodeling Lead to Moderately Decreased LV Function in Alzheimer Transgenic Mice After Myocardial Ischemia and Reperfusion.

ABSTRACT:

Background

Neurodegeneration and dementia are key factors in Alzheimer's disease (AD). The deposition of amyloid-ß into senile plaques in the brain parenchyma and in cerebral vessels known as cerebral amyloid angiopathy (CAA) are the main clinical parameters of AD. Acute myocardial infarction (AMI) and AD share a comparable pathophysiology. However, the underlying mechanisms and the consequences of AMI in AD patients are unclear to date.

Methods

AD transgenic APP23 mice were analyzed in experimental AMI using the closed-chest model.

Results

APP23 mice displayed significantly decreased left ventricular function as detected by FS/MPI (fractional shortening/myocardial performance index) after 24 h and 3 weeks after ligation of the LAD compared to WT controls. No differen
