PA catheterization uses decreases substantially in U.S.

Use of the pulmonary artery catheter decreased by 65 percent in the U.S. between 1993 and 2004, possibly due to growing evidence that this invasive procedure does not reduce the risk of death for hospitalized patients, according to a study in the July 25 issue of JAMA .

Heart patches that stimulate regeneration

When human hearts are injured, as during a heart attack, healthy tissue normally can't regrow.

Swift system for heart attack care improves treatment

Heart attack patients received lifesaving care up to an hour sooner after an Indiana hospital implemented a novel protocol to rapidly activate the cardiac catheterization lab, researchers reported in Circulation: Journal of the American Heart Association.

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.

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.

Catheter-based aortic valve replacement is set to take off

Twenty years ago, few interventional cardiologists could have imagined that during their professional careers it would be possible to replace a diseased aortic valve using catheter-based techniques, rather than open-chest surgery.

Stent thrombosis

Over the last year, it's been rare to utter the word "stent" without at least thinking "thrombosis," an uncommon but serious complication that's been on the minds of interventional cardiologists and patients alike.

Sticking with guidelines for acute coronary syndromes benefits even very elderly patients

Some say age 90 is the new age 70. If so, there's never been a better time for elderly patients to discuss with family and physicians just how aggressive medical care should be in case of a threatened or definite heart attack.

Advances in clinical cardiology

Three studies being presented at the American College of Cardiology's Innovation in Intervention: i2 Summit 2007 in New Orleans, La., highlight the breadth of research propelling advances in clinical cardiology.

Sodium Bicarbonate vs. Sodium Chloride in persons undergoing coronary angiography

In patients undergoing cardiac catheterization, contrast dye injection can sometimes cause contrast-induced nephropathy (CIN), otherwise known as acute renal failure.

New blood thinner thrombin-receptor antagonist may work without bleeding risk

When studying a new blood thinner, one of the first signs the drug is working is seeing a slight increase in minor bleeding, nose bleeds and bruising, an inconvenient side effect of preventing the blood clots that are the leading cause of heart attack and stroke.

Effect of Torcetrapib on the progression of coronary atherosclerosis

Investigators report that torcetrapib, a drug that substantially raises high-density lipoprotein cholesterol or HDL (the "good" cholesterol), did not slow the progression of plaque buildup in the coronary arteries as measured using an ultrasound probe (IVUS).

New system to speed critical care to acute heart attack patients

Mayo Clinic has designed a new system to speed critical care to acute heart attack patients that dramatically reduces the time that elapses before patients undergo a life-saving procedure -- by as much as 45 percent in some cases.

Drug-eluting stents are disappointing in bypass grafts - sometimes!

While drug-eluting stents are effective in keeping open bypassed heart veins that aren?t too diffuse (filled with cholesterol plaque), a new study by cardiologists at Jefferson Medical College shows that they fare less well in keeping open bypassed veins with longer blockages.

Heart attacks can give couples a new lease of life

A third of people who suffer heart attacks discover new meaning to their lives and reconnect with their partner, but others see it as a threat to their well-ordered existence, according to research published in the latest Journal of Advanced Nursing.

New technology offers alternative to open heart surgery

A new method of treating mitral regurgitation (MR), the leaking of blood through the mitral valve into the heart chamber, provides a less-invasive alternative to open heart surgery.

Broken heart syndrome common

In the largest review of "broken heart syndrome" patients ever conducted, Mayo Clinic researchers studied 100 patients and found symptoms recurred in 1 out of 10 patients over a four-year period, and that patients experiencing physical stress had a worse survival rate than those under emotional stress.

Speeding up initial treatment means more victims survive heart attacks

According to a newly published study, far more heart attack victims would survive if hospitals applied some simple, timesaving strategies.

Faster heart attack patients treated, the better their likelihood of survival

Hospitals that provide the most rapid emergency angioplasty have specific strategies to expedite the care of patients with heart attacks, researchers at Yale School of Medicine report in the November 13 New England Journal of Medicine.
