Cardiac enzyme rises post CABG predict worse outcomes

The significance of myocardial enzyme elevations following coronary artery bypass surgery (CABG) remains controversial.  Although a ‘significant’ enzyme rise is felt to indicate a worse long-term prognosis, several smaller studies have suggested that even small enzyme rises within 24hours of surgery are significant.  This analysis aimed to define whether a threshold exists below which enzyme […]

HDL function and atherosclerosis

There is a strong inverse relationship between serum levels of HDL and the risk of developing atherosclerotic cardiovascular disease.  This has fostered the search for pharmacological agents that raise HDL, but while several therapies have shown biochemical benefit – including nicotinic acid, fibrates and CETP inhibitors – there are little convincing data to associate these […]

IVUS reveals importance of non-culprit lesions

A substantial proportion of individuals who present with an acute coronary syndrome will go on to have repeat events, however the lesion related factors driving these repeat events remain poorly understood.  Data from retrospective and pathological studies have suggested that many lesions that lead to clinical events are thin-walled lipid-rich lesions that are angiographically mild […]

New genetic loci for MI and atherosclerosis found

Recent genome-wide association studies (GWAS) have identified several novel loci associated with coronary artery disease and myocardial infarction, however these represent only a small proportion of the inherited component of these disorders.  Furthermore, it is not clear whether these loci contribute to the development of atherosclerosis, or whether they may influence the stability of atherosclerotic […]

Statins show benefit regardless of CRP

Some previous studies – most noticeably the JUPITER trial – have suggested that the vascular benefits of statin therapy may be greater in the presence of inflammation.  C-reactive protein (CRP), a systemic marker of inflammation, has been associated with the risk of ischaemic heart disease, stroke, and vascular mortality, but its ability to act as […]
