When are stroke patients more likely to receive clot busting drugs?

by Todd Neale, MedPage Today Staff Writer

Patients suffering an acute ischemic stroke are about 20% more likely to receive clot-busting therapy with tissue plasminogen activator (tPA) if they arrive at the hospital on the weekend, a retrospective study showed.

When are stroke patients more likely to receive clot busting drugs? However, there was no difference in rates of inhospital mortality based on the time of admission, Abby Kazley, PhD, of the Medical University of South Carolina in Charleston, and colleagues reported in the January issue of Archives of Neurology.

Lipitor Tied To Diabetes Risk, More Evidence Shows

People on a high-dose regimen of the cholesterol drug Lipitor may have a slightly increased risk of developing type 2 diabetes -- particularly if they have several of the classic diabetes risk factors, a study published Monday finds.

A number of studies have linked Lipitor (known generically as atorvastatin) and other cholesterol-lowering statin drugs to a small increase in users' risk of diabetes.

This latest study, based on data from three large clinical trials, strengthens evidence of a connection.

But it also suggests that the risk may largely exist among people who also have the well-known risk factors for type 2 diabetes -- including excess weight, high blood sugar, elevated triglycerides (a type of blood fat) and high blood pressure.

Post-Stroke Depression Threatens Independence

The researchers examined data on 367 survivors of ischemic stroke, the type of stroke caused by a blood clot. The patients had an average age of 62, with no impairments in thinking or severe language problems.

One month after suffering strokes, 174 of the survivors were diagnosed with post-stroke depression.

The survivors’ level of independence was rated using a zero to five scale, with five representing the most severely dependent and disabled.

Three months later, 20% or 72 of the participants were considered dependent, scoring a level three or higher. But 80%, or 295 of the participants, were considered independent.

Sleep deprivation 'can cause strokes' | News | Nursing Times

Stroke or heart disease susceptibility is dependant on how much you sleep you get, a new study has suggested.

A Warwick Medical School study has discovered that prolonged sleep deprivation can have a seriously adverse effect on cardiac health.

The research team linked a lack of sleep to strokes, heart attacks and cardiovascular disorders which can often cause early death.

Professor Cappuccio and co-author Dr Michelle Miller examined evidence from more than 470,000 participants across eight countries, including Japan, the US, Sweden and the UK.

Professor Francesco Cappuccio said: “If you sleep less than six hours per night and have disturbed sleep you stand a 48% greater chance of developing or dying from heart disease and a 15% greater chance of developing or dying from a stroke.

“The trend for late nights and early mornings is actually a ticking time bomb for our health so you need to act now to reduce your risk of developing these life-threatening conditions.”

Dr Miller added chronic short sleep produces hormones and chemicals in the body, which increases the risk of developing heart disease and strokes, plus other conditions such as high blood pressure and cholesterol, diabetes and obesity.

Simple tests can tell who can drive after stroke, study finds - USATODAY.com

"A quick and objective screening in the doctor's office can help them to make more accurate decisions," said review author Hannes Devos, a research assistant at Katholieke Universiteit Leuven in Belgium.

However, several U.S. stroke experts said they weren't ready to accept the new study's findings.

The American Heart Association estimates that 6.4 million stroke survivors are alive in the United States today. While some patients are able to recover with few permanent disabilities, strokes can cause some people to permanently lose memory and the ability to properly move their bodies.

In some cases, patients with serious motor-skill problems can still drive a car as long as they're able to get proper equipment, such as an automatic transmission, a left-sided accelerator pedal for patients who have trouble moving their right side, and steering knobs that allow one-handed driving, Devos said

Carotid Artery Stenosis, American Heart Association

What is carotid artery stenosis or carotid artery disease?

Carotid artery stenosis is the narrowing of the carotid arteries. These are the main arteries in the neck that supply blood to the brain. Carotid artery stenosis, also called carotid artery disease, is a major risk factor for ischemic stroke. (This is the most common form of stroke and is usually caused by a blood clot plugging an artery.)

The narrowing is usually caused by plaque in a blood vessel. Plaque forms when cholesterol, fat and other substances build up in the inner lining of an artery. This process is called atherosclerosis.

How is carotid artery stenosis diagnosed?

Carotid artery stenosis may or may not cause symptoms. A doctor may hear an abnormal sound called a bruit (BROO'e) when listening to the artery with a stethoscope. The stenosis can be easily detected with an ultrasound probe placed on the side of the neck near the carotid arteries. This is called carotid ultrasonography.

How is carotid artery stenosis treated?

Depending on the degree of stenosis and the patient's overall condition, carotid artery stenosis can usually be treated with surgery. The procedure is called carotid endarterectomy. It removes the plaque that caused the carotid artery to narrow. Carotid endarterectomy has proven to benefit patients with arteries stenosed (narrowed) by 70 percent or more. For people with arteries narrowed less than 50 percent, anti-clotting medicine is usually prescribed to reduce the risk of ischemic stroke. Examples of these drugs are antiplatelet agents and anticoagulants.

Carotid angioplasty may be another treatment option. It uses balloons and/or stents to open a narrowed artery. 

For stroke information, call the American Stroke Association at 1-888-4-STROKE.

Patients With Blocked Carotid Arteries May Not Need Stroke Screening | National Nursing News

Patients with blocked neck arteries need screening for stroke risk only if they have other risk factors, according to new guidelines from the American Heart Association/American Stroke Association, American College of Cardiology and other groups.

A committee of stroke prevention specialists issued the guidelines after agreeing there is not sufficient evidence of benefit from widespread screening. The members hope the guidelines provide new information to help clinicians determine treatment approaches for their patients.

Screening is useful “if your doctor hears abnormal blood flow when listening to your [carotid] arteries, or if you have two or more risk factors for stroke (such as high cholesterol or a family history),” said Jonathan L. Halperin, MD, co-chairman of the writing committee and professor of medicine at the Mount Sinai School of Medicine in New York, in a news release.

Risk factors for stroke include age, family history of stroke, high blood pressure, high blood cholesterol, diabetes, obesity, atrial fibrillation, physical inactivity, sickle cell disease and other heart or blood vessel diseases.

The committee also issued recommendations regarding carotid endarterectomy and carotid stenting, two procedures for treating arteries. Both procedures are reasonable and safe, according to the committee, when arteries are more than 50% blocked.

“The guidelines support carotid surgery as a tried-and-true treatment for most patients,” said Thomas G. Brott, MD, committee co-chairman and professor of neurology and director of research at the Mayo Clinic campus in Jacksonville, Fla.

“However, for patients who have a strong preference for less invasive treatments, carotid stenting offers a safe alternative. Because of the anatomy of their arteries or other individual considerations, some patients may be more appropriate for surgery and others for stenting.”

This will be good news for people for who Carotid Endarterectomy has been suggested.
