BACKGROUND: Recent genome-wide association studies (GWAS) have identified associations with myocardial infarction and coronary artery disease (CAD), but the mechanisms underlying these associations remain largely unclear. Carotid intima-media thickness (IMT) is a measure of early arterial remodeling and arteriosclerosis. Therefore, if CAD associated SNPs are also associated with carotid IMT; ...

OBJECTIVE: Calcification in atherosclerotic plaques is a novel marker of atherosclerosis and is related to cardiovascular disease. However, its relationship with cerebrovascular disease has not been investigated extensively. We investigated the relationship between calcification in various vessel beds outside the brain and imaging markers of vascular brain disease. METHODS AND ...

Artery calcification reflects an admixture of factors such as ectopic osteochondral differentiation with primary host pathological conditions. We review how genetic factors, as identified by human genome-wide association studies, and incomplete correlations with various mouse studies, including knockout and strain analyses, fit into "pieces of the puzzle" in intimal calcification ...

BACKGROUND: The polygon of confluence (POC) represents the zone of confluence of the distal left main (LM), ostial left anterior descending [LAD], and ostial left circumflex [LCX] arteries. METHODS: We used intravascular ultrasound (IVUS) to assess the POC pre and post-drug-eluting stent implantation for unprotected distal LM disease. Four segments ...

The possible link between pulmonary fibrosis, anti-neutrophil cytoplasmic autoantibody (ANCA) positivity, and vasculitis is poorly understood. During the past 6 years, five retrospective case-control studies have been published. These studies suggest that pulmonary fibrosis (PF) is an underestimated manifestation of ANCA-associated vasculitis. Common clinical characteristics include older age (around 70 ...

Expert interpretation of modern noninvasive neuroimaging such as computed tomographic angiography (CTA) or MRA should detect nearly all aneurysms responsible for an isolated third nerve palsy. Whether a catheter angiogram should still be obtained in cases with negative CTA or MRA remains debated and mostly relies on whether the noninvasive ...

Dolichoectasia is a dilatation and elongation of the arteries, usually affecting intracranial basilar and vertebral arteries. It may cause posterior circulation stroke or transient ischemic attacks independent of atherosclerotic disease. Compression of cranial nerves or brainstem leads to hemifacial spasm, trigeminal neuralgia, or brainstem dysfunction (temporary or permanent). Intracranial bleeding ...
