Heparin effect on blood viscosity

Clinical Cardiology
H A RuggieroE S Caprissi


The effect of heparin on blood viscosity was investigated in a group of patients with acute myocardial infarction (AMI) and preinfarction angina (PA), whose blood viscosity was elevated. Viscosity was measured with Cannon, Fenske, and Routine viscometers. Kinematic viscosity, bath and whole blood, plasma, and serum viscosity were determined as well as dependent parameters (fibrinogen, serum proteins, number of platelets, and hematocrit). All of them were found to increase, and it was significantly proved that intravenous heparin immediately decreased plasma viscosity, but has a lesser effect on serum and whole blood viscosity. A dose of 1 cc = 50 mg = 5000 IU intravenous heparin, will maintain this decrease for a month. In our four-week-study, 1 cc i.v. heparin was administered at 6-hour intervals for the first 2 weeks, and 2 cc heparin subcutaneous injections were administered at 12-hour intervals for the next 2 weeks. We found that heparin also decreased fibrinogen, hematocrit, serum alpha 2 globulin, and number of platelets. Hyperviscosity, hypercoagulability, and the increase of platelet adhesiveness arae some of the most important physiopathological alterations of AMI and PA. The decrease of blood viscosity due to heparin ...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Lipidomics & Rhinovirus Infection

Lipidomics can be used to examine the lipid species involved with pathogenic conditions, such as viral associated inflammation. Discovered the latest research on Lipidomics & Rhinovirus Infection.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Torsion Dystonia

Torsion dystonia is a movement disorder characterized by loss of control of voluntary movements appearing as sustained muscle contractions and/or abnormal postures. Here is the latest research.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.
