    Heparin significantly reduces elevated blood viscosity in patients with acute myocardial infarction (AMI) and preinfarction angina (PA). This treatment also lowers key factors like fibrinogen and platelet count, improving patient outcomes.

    Area of Science:

    • Cardiovascular Medicine
    • Hematology

    Background:

    • Elevated blood viscosity is a significant pathological alteration in acute myocardial infarction (AMI) and preinfarction angina (PA).
    • Understanding the impact of therapeutic interventions on blood rheology is crucial for managing these cardiovascular conditions.

    Observation:

    • This study investigated the effects of heparin on blood viscosity and related parameters in patients with AMI and PA.
    • Viscosity measurements included kinematic, whole blood, plasma, and serum viscosity, alongside fibrinogen, serum proteins, platelet count, and hematocrit.

    Findings:

    • Intravenous heparin demonstrated an immediate and significant decrease in plasma viscosity.
    • Heparin also reduced serum viscosity, whole blood viscosity, fibrinogen levels, hematocrit, serum alpha 2 globulin, and platelet count.

  • A sustained reduction in blood viscosity was observed for up to one month with a consistent heparin dosage regimen.

    • Implications:

    • Heparin's ability to decrease blood viscosity, hypercoagulability, and platelet adhesiveness offers substantial benefits in managing AMI and PA.
    • These findings highlight heparin as a critical therapeutic agent for improving hemorheological profiles in cardiovascular disease patients.
    • Further research can explore optimal heparin dosing strategies to maximize rheological benefits in acute cardiac events.
