ARB not found to benefit AF

Whilst reducing blood pressure reduces the risk of heart failure and stroke this relationship has thus far not been demonstrated in patients with atrial fibrillation.  This is despite the fact that recent mechanistic work and retrospective analyses have suggested that both ACE inhibitors and ARBs have specific properties that alter atrial mechanical and electrical remodelling […]

No benefit from platelet testing post PCI

Clopidogrel is a prodrug that needs to be converted into an active metabolite in order to be active, however wide interindividual variability has been noted both in the concentration of active metabolite and also platelet responsiveness.  The GRAVITAS (Gauging Responsiveness with A VerifyNow assay – Impact on Thrombosis and Safety) aimed to investigate the effect […]

2-year RESOLUTE data emphasise need for secondary prevention

The RESOLUTE All Comers trial showed that the Resolute zotarolimus-eluting stent was non-inferior to the Xience V everolimus eluting stent in terms of target lesion failure (revascularisation, myocardial infarction, or cardiac death).  However, long-term follow-up data from drug-eluting stent trials are generally scarce.  Silber et al. report the 2-year clinical outcomes from the original RESOLUTE […]

Novel diagnostic pathway improves chest pain assessment

Although 75-85% of patients presenting to the emergency department with chest pain ultimately do not receive a diagnosis of acute coronary syndrome, a lengthy assessment process is still mandatory as patients with a missed diagnosis of myocardial infarction are at increased risk for a cardiovascular event.  Than et al. prospectively validated the safety of a […]

High-sensitivity troponin assay improves patient outcomes

In recent years clinical troponin assays have become increasingly sensitive, however whether this translates into improved clinical outcomes for patients with suspected acute coronary syndromes (ACS) has not previously been examined.  Mills et al. investigated whether the introduction a new, high-sensitivity, troponin assay led to an improvement in patient outcomes. […]

Molecular Imaging of Atherosclerosis using MRI

Using invasive imaging techniques such as intra-vascular ultrasound, the burden of atherosclerotic plaque disease in any given individual has previously been shown to correlate with the likelihood of future cardivascular events .  Magnetic Resonance Imaging (MRI) has the advantage of being non-invasive and, compared to other currently available molecular imaging modalities, it has good spatial […]

9p21 link to coronary disease clarified

Genome-wide association studies (GWAS) are examining the human genome in ever-greater depth in the hope of finding common variants that explain the heritability associated with common diseases such as coronary artery disease.  Despite the ever increasing scale of these big-science ‘super-projects’ with literally tens of thousands of cases and controls, only a small proportion of […]
