Imaging technique accurate in aneurysm detection and therapy planning

Multidetector computed tomography (MDCT) angiography is highly accurate in depicting intracranial aneurysms, according to a study published in the August issue of Radiology.

Cancer risk from radiation during cardiac CT scans studied

An analysis based on computerized simulation models suggests that the lifetime risk of cancer associated with radiation exposure from a computed tomography (CT scan) coronary angiography varies widely, with the risk greater for women and younger patients, according to a study in the July 18 issue of JAMA .

Study shows inaccuracies in cardiac PET-CT imaging

Current PET-CT scanners with standard commercial software designed to provide images of the heart are falsely indicating coronary artery disease in as many as 40 percent of patients, according to a study published today on the cover page of the Journal of Nuclear Medicine.

Truth on postmenopausal hormone therapy and coronary disease

With each new publication of coronary artery disease (CAD) data from the Women's Health Initiative (WHI) study, the inevitable reaction is ,Why on earth did the WHI investigators claim in 2002-2004 that postmenopausal hormone therapy has deleterious effects on the risk for CAD, when, from the beginning, they were aware of the importance of the age factor in this clinical scenario".

Obese heart attack patients more likely to survive after treatment than normal weight patients

Obese and very obese patients have a lower risk of dying after they have been treated for heart attacks than do normal weight patients, according to research published in the European Heart Journal today (Wednesday 20 June).

Standards for the use of ultrasound to measure narrowing of the carotid artery may be too aggressive

These standards, used by the majority of vascular laboratories around the country since the early 1980s, were based on the use of angiography, a medical imaging technique in which an X-ray picture is taken to visualize the inner opening of blood filled structures.

Combining molecular imaging technologies to stop/prevent heart attacks

The use of combined imaging technologies may hold the key to stopping and even preventing heart attacks, according to research reported at the 54th Annual Meeting of SNM, the world's largest society for molecular imaging and nuclear medicine professionals.

Molecular imaging provides a better way to visualize heart disease

Technically advanced molecular imaging provides a 3-D way to significantly improve the diagnosis of heart disease, according to researchers at the 54th Annual Meeting of SNM, the world's largest molecular imaging and nuclear medicine society.

Same-day coronary angiography and surgery safe for many patients

Mayo Clinic researchers discovered it is safe -- and much more convenient and less costly -- for many patients to undergo coronary angiography and elective valve surgery on the same day, it is reported in the current issue of Mayo Clinic Proceedings.

Obstructive sleep apnea increases a person's risk of having a heart attack

The nighttime breathing disorder known as obstructive sleep apnea increases a person's risk of having a heart attack or dying by 30% over a period of four to five years, according to a study presented at the American Thoracic Society 2007 International Conference, on Monday, May 21.

Long-term treatment with anti-clotting drug clopidogrel improves stenting outcomes in diabetic patients

A study showing that diabetic patients who are treated with long-term anti-clotting therapy are less likely to have a heart attack or die more than a year after stenting has been named among the best research papers presented at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI).

Minimally invasive treatment of chronic mesenteric ischemia

Using catheter techniques perfected in the arteries of the heart, interventional cardiologists are successfully treating chronic mesenteric ischemia, a condition akin to intestinal angina.

High-dose clopidogrel before stenting cuts heart attack risk in half

Pretreatment with double-dose anticlotting medication just before percutaneous coronary intervention (PCI) cuts the combined risk of heart attack and cardiac death by half, according to a study reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), May 9-12, 2007, in Orlando, FL.

Role of PCI and coronary artery bypass grafting for the treatment of patients with left main coronary artery disease

Coronary artery bypass surgery has been the preferred treatment for patients with a blockage in the left main coronary artery, the conduit that supplies blood to about two-thirds of the heart.

Is the 90-minute deadline for inflation of angioplasty balloons really critical?

In the treatment of heart attack, the 90-minute goal for inflation of an angioplasty balloon in a blocked coronary artery to restore normal blood flow is so revered it's been codified in clinical guidelines, accreditation standards, and pay-for-performance programs.

Bare metal stents provide a safer choice

While drug-eluting stents are effective in keeping open diseased heart arteries, they should not be used for patients who need to have non-cardiac surgery a short time after an interventional heart procedure.

Mending broken hearts

The causes of "broken heart syndrome" remain a mystery, but doctors will soon have an easier time recognizing and treating this rare, life-threatening condition, thanks to data being reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), May 9-12, 2007, in Orlando, FL.
