Coronary angioplasty improves survival in all patients with out of hospital cardiac arrest

Coronary angioplasty improves survival in all patients with out of hospital cardiac arrest, according to research presented at the Acute Cardiac Care Congress 2012. The study was presented by Dr Annamaria Nicolino from the Santa Corona General Hospital in Pietra Ligure, Italy.

$Noninvasive fractional flow reserve still out of reach$

Noninvasive fractional flow reserve still out of reach

A novel, noninvasive approach to determining fractional flow reserve failed to show sufficient diagnostic accuracy to meet the primary endpoint of the DeFACTO trial, but was more accurate for diagnosing coronary artery ischemia than computed tomography, reported the trial’s lead investigator.

Renal artery stent revascularization reduces blood pressure in patients with severe hypertension

Patients with uncontrolled renovascular hypertension saw a significant improvement in their blood pressure with renal artery stent deployment. The multicenter HERCULES trial, evaluating the safety and effectiveness of the RX Herculink Elite Stent, found that patients with higher blood pressure levels at baseline had the most dramatic reduction in blood pressure following intervention.

Fractional flow reserve CT shows potential to non-invasively identify coronary artery disease

A study published in the most recent issue of the Journal of the American Medical Association (JAMA) presented encouraging news regarding physicians' ability to determine blood flow and associated coronary artery disease (CAD) using noninvasive CT scanning technology.

Study finds decline in 30-day mortality of acute myocardial infarction with improved treatment

Improved treatment after acute myocardial infarction and less severe patient profile have reduced 30-day mortality over the past 15 years, according to research presented at ESC Congress 2012.

Ultra-fast 320-detector CT scanner can accurately diagnose arterial blockages

An ultra-fast, 320-detector computed tomography (CT) scanner can accurately sort out which people with chest pain need - or don't need - an invasive procedure such as cardiac angioplasty or bypass surgery to restore blood flow to the heart, according to an international study. Results of the study, which involved 381 patients at 16 hospitals in eight countries, are scheduled to be presented at the European Society of Cardiology Congress in Munich, Germany, on August 28.

Addition of CTP to CT angiography allows clinicians to identify flow-limiting coronary artery disease

A non-invasive imaging strategy which integrates non-invasive CT angiography (CTA) and CT myocardial perfusion imaging (CTP) has robust diagnostic accuracy for identifying patients with flow-limiting coronary artery disease in need of myocardial revascularisation, according to results of the CORE320 study presented here today by Dr Joao AC Lima from Johns Hopkins Hospital, Baltimore, USA.

Rural and urban areas equally likely to receive endovascular aneurysm repair care

A new study published in the September issue of Journal of Vascular Surgery reveals that rural and urban patients have equivalent access to endovascular aneurysm repair (EVAR) care from vascular surgeons, increased referral to high-volume hospitals and improved outcomes after repair.

$Noninvasive fractional flow reserve superior to CT in identifying individuals with ischemia$

Noninvasive fractional flow reserve superior to CT in identifying individuals with ischemia

Among patients with suspected or known coronary artery disease, use of a method that applies computational fluid dynamics to derive certain data from computed tomographic (CT) angiography demonstrated improved diagnostic accuracy vs. CT angiography alone for the diagnosis of ischemia, according to a study being published online by JAMA.

Bleeding risk from aneurysm high in hemorrhagic AVM radiosurgery

In patients undergoing stereotactic radiosurgery for hemorrhagic arteriovenous malformations, endovascular or surgical strategies that reduce bleeding risk should be used if an aneurysm is found, advise US researchers.

Research roundup: Disparities in head scans; Unnecessary heart tests; Americans hit the walkway

Among children who suffered minor blows to the head, whites were more likely to receive unneeded cranial CT scans in the ED than were blacks or Hispanics, researchers found.
