Coronary CTA is a low cost, non-invasive alternative for evaluating coronary artery disease

Coronary CTA offers a low cost, non-invasive alternative to conventional angiography for evaluating patients who are suspected of having coronary artery disease; true even if the patients have calcified coronary artery plaques, according to a study performed at the Thomas Jefferson University Hospital, Philadelphia, PA.

Latest glaucoma research

Glaucoma-related highlights of today's scientific program of the 2008 Joint Meeting of the American Academy of Ophthalmology (Academy) and European Society of Ophthalmology (SOE) include a study that correlates optic nerve damage in glaucoma patients with carotid artery narrowing and potentially elevated risk for stroke, and a survey that looks at how the practice of fasting, common to the world's seven major religions, may affect patient compliance with treatment for glaucoma and other eye diseases.

Vulnerable plaque may be easier to detect through optical coherence tomography

Research results indicate that optical coherence tomography (OCT), a newly evolving imaging method, may be the best tool available to detect vulnerable plaque in coronary arteries. The findings will be presented at the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF).

New devices used to reduce arterial occlusions, provide cardiac support

Research results highlighting three new devices used to reduce blockages in peripheral and coronary arteries and to provide cardiac support will be presented at the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF).

Results from the Simvastatin and Ezetimibe in aortic stenosis study

The SEAS (Simvastatin and Ezetimibe in Aortic Stenosis) study has investigated the effects of intensive cholesterol lowering with the combination of simvastatin (40 mg daily) and ezetimibe (10 mg daily) in patients with aortic stenosis.

Transcatheter aortic valve replacement - a new frontier in cardiovascular medicine

Replacing heart valves without the substantial trauma of opening the chest and the heart were little known concepts until the groundbreaking pulmonary and aortic transcatheter valve replacements performed during 2000 and 2002, respectively by Philipp Bonhoeffer and Alain Cribier.

Transapical aortic valve implantation

Transapical aortic valve implantation (TA-AVI) is a new therapeutic strategy, which has been implemented successfully into clinical practice in several hundred patients suffering symptomatic aortic stenosis and an increase perioperative risk during the past two years. The Edwards SAPIEN prosthesis has been used.

Ultrasound imaging predicts heart attack risk

Repeat exams using widely available and inexpensive ultrasound imaging could help identify patients at high risk for a heart attack or other adverse cardiovascular events, according to a study published in the September issue of the journal Radiology.

New minimally invasive procedure successfully eliminates pain and disability caused by lumbar spinal stenosis

Early clinical results from the US and Argentina reveal that a new minimally invasive procedure successfully eliminates pain and disability caused by lumbar spinal stenosis (LSS), a condition that, in severe form, can cripple sufferers.

Plant sterols to lower cholesterol have risks

Plant sterols have been touted as an effective way to lower cholesterol and reduce the risk of heart disease. However, a research study in the July JLR has uncovered that these compounds do have their own risks, as they can accumulate in heart valves and lead to stenosis.

New treatments for lower back pain tested

"This is one of the most frustrating complaints that patients have as they get older." Physicians are testing two drugs approved to treat other conditions to see whether they might also help patients who have severe pain in their lower back and in their legs.

Z-plasty helps patients breathe easier

Z-plasty, a minimally invasive surgical technique to treat internal nasal valve collapse, showed significant improvement in relieving nasal obstruction with less recovery time compared to more traditional open rhinoplasty, according to a research study by Rush University Medical Center. The study findings are published in the May 21 issue of the Archives of Facial Plastic Surgery, one of the JAMA/Archives journals.
