Educational programs, increased physician collaboration can reduce inappropriate CCTA use

Appropriate use of testing is a hot topic in medicine as physicians and hospitals look for ways to improve quality while containing cost to achieve high-value care. This is especially true in the field of cardiology where the potential consequences of incorrect diagnosis have led to overuse of cardiovascular imaging with CT scanners, called coronary CT angiography.

Early CT ‘definitive’ for subarachnoid hemorrhage diagnosis

Cerebrospinal fluid analysis is only necessary for patients with thunderclap headache and a negative computed tomography scan if they undergo imaging more than 6 hours after headache onset, research suggests.

Prior contralateral amputation predicts outcomes after LEB for critical limb ischemia

Researchers from the Vascular Study Group of New England (VSGNE) report that prior contralateral amputation predicts worse outcomes for lower extremity bypasses (LEB's) performed in the intact limb.

Specific autoantibodies associated with blood vessel damage in the brain

The presence of specific autoantibodies of the immune system is associated with blood vessel damage in the brain. These findings were made by Marion Bimmler, a graduate engineer of medical laboratory diagnostics at the Max Delbr-ck Center for Molecular Medicine Berlin-Buch and Dr. Peter Karczewski of the biotech company E.R.D.E.-AAK-Diagnostik GmbH in studies on a rat model.

CT angiography use ‘unwarranted’ in chest pain patients

Using coronary computed tomography angiography to triage patients with chest pain reduces time to discharge from the emergency department by nearly a third, researchers report in The New England Journal of Medicine.

Paramedics could up their game to meet reperfusion guidelines

Researchers say that Canadian guidelines for reperfusion in ST-segment-elevation myocardial infarction can only be met if electrocardiograms are administered by paramedics.

Blood flow in blocked arteries to extremities improved by new angioplasty procedure

Patients with blocked arteries to their extremities, known as peripheral artery disease (PAD) or critical limb ischemia (CLI), may now find relief from lower leg pain and wounds caused by impaired leg artery circulation with the previously unproven therapy, percutaneous transluminal angioplasty (PTA).

Training EMS to interpret ECGs can expedite treatment for severe heart attacks

A new program that trains emergency medical service technicians (EMS) to read electrocardiograms so that they can evaluate patients with chest pain, and expedite treatment for the severe heart condition known as ST-segment elevation myocardial infarction (STEMI), a serious form of heart attack, has excellent results and should become the standard of care, according to two studies published in the current issue of the Canadian Journal of Cardiology.

AstraZeneca plans to conduct ticagrelor plus clopidogrel clinical trial for PAD

AstraZeneca today announced plans to conduct the EUCLID study, a global clinical trial involving 11,500 patients with peripheral artery disease (PAD), a condition affecting approximately 27 million people in Europe and North America.

AHA statement addresses varied cardiac evaluation and management of transplant patients

As thousands of Americans await a life-saving kidney or liver transplant, medical teams are paying close attention to another organ: their hearts. This month the American Heart Association attempts to bring harmony to the varied cardiac evaluation policies created at U.S. hospitals that assess a patient's overall health before transplant surgery.

New method uses acoustic angiography to identify cancer in minutes

From the air, the twists and turns of rivers can easily be seen. In the body, however, tracing the twists and turns of blood vessels is difficult, but important. Vessel "bendiness" can indicate the presence and progression of cancer.

Site of care linked to racial imaging disparities in stroke

Patients with stroke are less likely to undergo carotid artery imaging if they are treated at a hospital that serves a population with a high proportion of minority ethnicities, say researchers.

Currently available online information about abdominal aortic aneurysms need improvement

During the last decade use of the Internet has begun to pervade all aspects of modern life, including an "e-health revolution" where patients may research health issues online before seeking professional consultation. However according to researchers from Leeds in the United Kingdom (U.K), the quality and readability of online patient information specifically for abdominal aortic aneurysms (AAAs) is poor and requires significant improvement.

Prevalence of significant CAD in patients with chest pain symptoms is lower than expected in Europe

Preliminary findings from the EVINCI study show that the prevalence of "significant" coronary artery disease in patients with chest pain symptoms is lower than expected in Europe. In as much as 75% of this population an accurate non-invasive screening could avoid unnecessary and costly invasive procedures.

Registry proves invaluable for fibromuscular dysplasia patients

A patient registry is proving invaluable in cataloging the clinical features, symptoms, severity, and outcomes of fibromuscular dysplasia (FMD), a non-inflammatory vascular disease that can cause narrowing of arteries in the carotid (neck) and renal (kidney) arteries, which can result in headache, strokes, and aneurysms.
