In angioplasty procedures, a balloon is fed through a catheter and used to prop open an artery that has become narrowed or blocked. In cases where stenting is appropriate, a stent mounted on a balloon is inserted and inflation of the balloon expands the stent against the blocked artery wall to hold the vessel open. The balloon is then deflated and the catheter is withdrawn. Stent treatment of arteries holds them open and improves blood flow to the heart. In cases where post-dilatation is needed, a high-pressure balloon is inflated inside a stent to help better place the stent against the vessel wall.
Use of the antiplatelet drug clopidogrel before a coronary angioplasty reduced the risk of cardiovascular death, heart attack or stroke within 30 days following the procedure, according to an article in the September 14 issue of JAMA: The Journal of the American Medical Association.
According to new research if patients are given the a drug which reduces platelet activity in the blood risk of heart attack and cardiovascular death before and after angioplasty is reduced.
According to a new study when it comes to heart bypass surgery, women are nearly twice as likely as men to die from complications.
Boston University School of Medicine (BUSM) researchers have discovered that patients who have either coronary artery bypass graft surgery or coronary angioplasty are at an increased risk of developing Alzheimer's disease.
Heart attack patients treated with primary percutaneous intervention (PCI) at hospitals after hours and on weekends wait longer to receive clot busters and other treatments and have a higher risk of death than those treated during regular hospital hours
Two newly released studies in the U.S. have to some extent come to conflicting results. According to one study, by researchers at Emory University, attempts over the last decade to address race and gender disparities in the treatment of U.S. patients hospitalized for heart attacks, still in some respects raise cause for concern.
Before patients get their clogged heart arteries re-opened, they may want to ask their doctor just how many such procedures he or she has done, a new study finds. The answer may make a big difference in each patient's risk of suffering a major setback before leaving the hospital.
Emergency bypass surgery or angioplasty procedures to counteract deadly complications that follow some heart attacks not only improve survival odds for cardiogenic shock patients, but the quality of life after such emergency revascularization procedures appears to be better than that of survivors who received less aggressive treatment, according to a new study in the July 19, 2005, issue of the Journal of the American College of Cardiology.
Patients with peripheral arterial disease (PAD) are more likely to have a foot or leg amputated if they live in a region that has few vascular surgeons, according to a Rice University/Baylor College of Medicine study published in the July issue of the Journal of Vascular Surgery.
More tests need to be prescribed to save and prolong the lives of Canadians living with coronary artery disease, says a study released from the University of Alberta.
Pointing out that not all coronary artery bypass operations are performed the same way or have equivalent outcomes, cardiothoracic surgeons at Cedars-Sinai Medical Center have found that patients who have blockages of multiple coronary arteries and undergo "complete revascularization" - grafting of arteries to restore blood flow to all affected territories of the heart - have consistently better long-term survival rates than those who have "incomplete revascularization."
A significantly lower risk of heart disease can now be added to the list of proven long-term benefits of tight glucose control in people with type 1 diabetes.
PrognostiX, a start-up company based on Cleveland Clinic technology, has received approval from the U.S. Food and Drug Administration to begin selling a diagnostic test capable of identifying patients who are in imminent danger of heart attack or death.
Fear of public reporting of mortality rates may explain why cardiologists in New York are less likely than cardiologists in Michigan to perform angioplasty and other percutaneous coronary interventions on higher risk patients, according to a new study in the June 7, 2005, issue of the Journal of the American College of Cardiology.
A study of nearly 60,000 patients has found that people with several clogged heart arteries did better if they had bypass surgery rather than a less-drastic procedure in which the blood vessels are propped open with tiny mesh cylinders called stents.
Conditions such as abdominal obesity, high blood pressure, abnormal cholesterol levels and high blood sugar are problematic enough for people all on their own.
A group of researchers of the Institute of Biophysics (Russian Academy of Sciences), Krasnoyarsk regional clinical hospital and Krasnoyarsk regional department of morbid anatomy under the guidance of .I. Gitelzon, Academician of Russian Academy of Sciences, have tested characteristics of a new polymeric coating for vascular stents.
The World Health Organisation has predicted an increase in the worldwide prevalence of diabetes of epidemic proportions . Eighty percent of people with diabetes will die from cardiovascular complications -- stroke and/or coronary heart disease (CHD).
A type of coronary artery stent that releases a medication appears to result in better outcomes than traditional stents for heart attack patients, according to a study in the May 4 issue of JAMA.
The first patient undergoes treatment today in a new prospective randomised trial, called the SUPER Study, to compare stenting with balloon angioplasty in patients with superficial femoral artery (SFA) occlusions caused by peripheral artery disease (PAD).
