Polymorphisms and noncardioembolic stroke in three case-control studies.

Background: Gene variants associated with disease could reveal novel mechanisms. We searched for single nucleotide polymorphisms (SNPs) associated with noncardioembolic stroke (nonCES).

Methods: We tested 24,926 SNPs in or near genes for association with nonCES in the Vienna Study (551 cases, 815 controls) and then evaluated the associated SNPs in the UCSF-CC Study (570 cases, 1,604 controls) first in pooled DNA samples and then in individual DNA samples.

A transient improvement in renal function occurs after ischemic stroke.

Background: Neurohumoral effects have been suggested to affect kidney function. Stroke is a condition where regulation of the renin-angiotensin system and sympathetic nerve activity are altered.

Methods: Renal function as estimated by serum creatinine was analyzed over 1 week in 220 patients after acute ischemic stroke.

Evaluation of the PC-1 K121Q and G2906C variants as independent risk factors for ischaemic stroke.

Unlabelled: Overexpression of plasma cell membrane glycoprotein-1 (PC-1) inhibits insulin receptor tyrosine kinase activity and thus favours insulin resistance and atherosclerotic vascular disease. Recent findings indicate that the minor variant K121Q in the PC-1 gene confers an increased risk for early myocardial infarction independent of other established risk factors. We hypothesized that genetic variants in PC-1 may also influence the risk for cerebrovascular disease.

Clinical predictors of death in young and middle-aged patients with ischemic stroke or transient ischemic attack: long-term results of the Vienna Stroke Registry: clinical predictors of ischemic stroke mortality in patients <60 years.

Data on long-term survival of younger patients with ischemic stroke (IS) are limited. We assessed mortality rates and clinical predictors of survival in patients with IS or transient ischemic attack (TIA) <60 years. Consecutive patients with IS or TIA <60 years admitted to nine neurological departments in Vienna between 1998 and 2001 were included into the current study.

Polymorphisms associated with both noncardioembolic stroke and coronary heart disease: vienna stroke registry.

Noncardioembolic stroke and coronary heart disease (CHD) may share genetic predispositions. We tested the hypothesis that genetic variants which are associated with risk of CHD would also be associated with risk of noncardioembolic stroke in 562 cases from the Vienna Stroke Registry and 815 controls. We selected 6 gene variants that had been consistently associated with risk of CHD in 3 studies, including the Atherosclerosis Risk in Communities study, and found that 4 of these gene variants were also associated with risk of noncardioembolic stroke.
