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.

Patent foramen ovale (PFO) and atrial septal defect (ASD) closure

A PFO and an ASD are congenital structural heart diseases characterized by a communication between heart chambers at the level of the wall (septum) separating them. These chambers are the left and right atrium as shown on the picture below. The right atrium receives (dark) oxygen-depleted blood from the great veins, while the left atrium receives (red) oxygen-rich blood from the lungs.

Immediate emergency angioplasty can save the lives of those experiencing MI

We have demonstrated that patients who have an acute myocardial infarction and are admitted to a hospital which has no possibility to perform direct angioplasty, benefit from being transferred immediately after having received thrombolytics to a hospital where angioplasty (percutaneous coronary intervention, PCI, often including stent implantation) can be immediately performed.

How to optimally prepare a patient for planned coronary angiography and subsequent angioplasty?

A Czech study compared two anti-clotting treatment regimens, currently used before coronary angiography / angioplasty to find the optimal balance between preventing ischemic versus bleeding complications of these procedures. The study was conducted in five Czech tertiary cardiology centers.

DES: friend or foe?

The current FDA approved stents (CYPHER and TAXUS) have been associated with late stent thrombosis (LST) (>30days following implantation) however, the mechanisms predictive of LST are poorly understood. Pathologic studies are one of the best methods for detailed analysis of morphologic changes that occur after placement of Drug Eluting Stents to determine the causes of LST.

Long term follow up of additional Swedish registry data does not indicate an increased

Four years of follow up including additional patients in the Swedish Coronary angiography and angioplasty registry (SCAAR) does no longer indicate any increased mortality in patients treated with drug eluting stents compared to patients treated with bare metal stents.

Australian researchers discover a 'novel molecular dictator with a conscience'

University of New South Wales (UNSW) researchers have uncovered an important naturally occurring mechanism in the body where "bad" cells that cause blockages in our blood vessels are kept under strict growth control, while "good" cells that keep our blood vessels free of clots and growths are left unaffected.
