Abstract

Since measurements of AT III and other possible coagulation inhibitors might provide an index of hypercoagulability, the goal was to measure over a 3-month period individual changes in blood levels of AT III, alpha 2-microglobulin, and alpha 1-antitrypsin in 51 patients with acute ischemic heart disease who were admitted to a Coronary Care Unit with the following diagnosis: unstable angina (26 patients), acute transmural myocardial infarction (20 patients), or subendocardial myocardial infarction (5 patients). Some patients received prophylactic antithrombotic therapy. AT III was measured by the von Kaulla, Owen, Thrombo-Screen, chromogenic, immunodiffusion, and immunoelectrophoretic methods. Alpha 2-macroglobulin and alpha 1-antitrypsin were measured by immunodiffusion. All inhibitors were measured on three different occasions: (1) on admission to hospital, (1) day of departure from hospital, and (3) at 3 months after hospitalization. Alpha 1-antitrypsin showed a significant increase compared to the control and remained elevated during the 3-month interval. Compared to normal control values, AT III was found to be significantly diminished when measured by one functional method (von Kaulla) in all three blood samples from patie...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Ataxia telangiectasia (MDS)

Ataxia telangiectasia is a rare neurodegenerative diseases caused by defects in the ATM gene, which is involved in DNA damage recognition and repair pathways. Here is the latest research on this autosomal recessive disease.
