Blood Clot News and Research

RSS

A Blood Clot is a mass of blood that forms when blood platelets, proteins, and cells stick together. When a blood clot is attached to the wall of a blood vessel, it is called a thrombus. When it moves through the bloodstream and blocks the flow of blood in another part of the body, it is called an embolus.

New molecule could be key to anti-heart attack drug

When too many blood platelets stick together in the bloodstream, they form dangerous clots that can clog blood vessels and cause a heart attack. If a clot doesn't get dissolved or rapidly removed, it can cause permanent damage or even death.

Matrix registry probes adherence to clopidogrel at 1 year

A large community-based registry of patients treated with drug-eluting stents is providing important insight into how long patients with complex coronary artery disease typically stick to their doctors' orders to take clopidogrel, a drug that prevents unwanted blood clots; why they stop taking the drug; and the long-term consequences of that decision.

Two drug combo blood pressure therapy lowers cardiovascular risk

An international blood pressure study comparing two single-pill drug combinations has yielded results so significant that the study has been stopped early and the researchers say their findings might alter the way high blood pressure is treated worldwide.

Study gives nod to drug-eluting stents in heart attack

Although drug-eluting stents have become widely used for the treatment of stable coronary artery disease, many cardiologists choose bare-metal stents for patients with heart attack, or myocardial infarction (MI), citing conflicting data about the safety and effectiveness of drug-eluting stents in this patient group.

Drug-eluting stents outperform bare-metal stents

New evidence from a large randomized study is answering important questions about the best approach to percutaneous coronary intervention (PCI) in patients with a type of heart attack known as ST-segment-elevation myocardial infarction (STEMI).

Special catheter that clears debris from artery helps blood flow in percutaneous coronary intervention

Use of a special catheter that sucks out, or aspirates, bits of plaque and blood clot that break loose during percutaneous coronary intervention (PCI) significantly enhances blood flow deep in the heart muscle in patients who are experiencing a heart attack, according to a recently published study.

Repeated episodes of stent thrombosis common

When a clot develops inside a coronary stent, it can block blood flow to the heart, potentially causing a heart attack or even death.

Cigarette smokers treated for brain aneurysm with coil embolization at higher risk of recurrence

Cigarette smokers who were treated for cerebral aneurysms with coil embolization (blocking of a blood vessel) are at greater risk of developing another aneurysm, say neurological surgeons at Jefferson Hospital for Neuroscience in Philadelphia in the first-known study of its kind.

Damaged veins heal faster with heparin treatment, laboratory study finds

A commonly used medication that prevents blood clots from forming may also prevent existing clots from damaging delicate vein walls and may accelerate healing in a clot-damaged area of vein wall, according to new research from the University of Michigan Cardiovascular Center.
