Using mathematical model, Herschel-Bulkley fluid, the study examined how Acetylsalicylic Acid influences blood flow characteristics and prevents clot formation. The findings reveal that Acetylsalicylic Acid reduces resistance to flow, particularly in arteries with stenosis, by diluting blood, lowering viscosity, and decreasing blood pressure. Graphical representations validated these findings and compared them with previous studies. Overall, the research highlighted Acetylsalicylic Acid 's potential as a therapeutic agent for managing cardiovascular disorders by modulating blood flow dynamics and inhibiting thrombus formation.

Introduction Cardiovascular diseases (CVDs) remain a leading cause of morbidity and mortality worldwide, necessitating continuous exploration of therapeutic interventions. Acetylsalicylic Acid, a widely used medication, has garnered attention for its potential cardiovascular benefits, particularly in preventing thrombus formation and improving blood circulation [3,15,45]. Acetylsalicylic Acid, a nonsteroidal anti- inflammatory drug, exerts its antithrombotic effects primarily by inhibiting the enzyme cyclooxygenase, thereby reducing the synthesis of prostaglandins and thromboxanes. Beyond its analgesic and anti-inflammatory properties, Acetylsalicylic Acid's ability to inhibit platelet aggregation and thrombus formation has been extensively studied [7,34,44]. However, the precise mechanisms underlying its effects on blood circulation dynamics and thrombus formation warrant further investigation. Stenosis refers to the narrowing of blood vessels, often due to the buildup of plaque, which can impede blood flow and lead to serious health complications such as heart attacks and strokes [18,26,36]. The formation of a blood clot, or thrombus, within an artery can obstruct the flow of blood to downstream tissues, depriving them of oxygen and nutrients [10,16,46]. Many studies has done to understand how Acetylsalicylic Acid, a well-known antiplatelet agent, mitigates this risk by inhibiting platelet aggregation and clot formation. By exploring the intricate interplay between Acetylsalicylic Acid, blood flow, and arterial stenosis, some researches shaded light on the mechanisms underlying its therapeutic effects in cardiovascular disease. To achieve this, some researchers has done mathematical modeling techniques to simulate blood flow dynamics within multi- stenosed arteries [5,37,43]. These models take into account various factors that influence blood flow, including viscosity, pressure gradients, and geometric irregularities caused by arterial narrowing. By solving the equations governing blood flow under different conditions, to assessed how Acetylsalicylic Acid affects key hemodynamic parameters such as flow velocity, pressure distribution, and shear stress within the stenotic artery. The results of the study have provided valuable insights into the effects of Acetylsalicylic Acid on hemodynamics in the context of arterial stenosis [24,38,49]. By analyzing the data obtained from mathematical simulations and graphical representations, it is obtained how Acetylsalicylic Acid alters blood flow patterns and mitigates the risk of thrombus formation. Recent research underscores the pivotal role of Acetylsalicylic Acid in modulating blood flow dynamics and preventing clot formation in multi- stenosed arteries [29,39,41,53]. By elucidating the complex interactions between Acetylsalicylic Acid, blood flow, and arterial pathology, the results offered valuable insights that may inform the development of novel therapeutic strategies for cardiovascular disease management. Some researchers derived a general equation of motion for viscous fluid flow through a porous medium, highlighting its significance in both theoretical and practical contexts and explored the effects of stenosis in arteries using Power-law and Casson- model fluids, while also discussed biorheological aspects and peripheral layer viscosity effects on blood flow [4,28,50]. Researchers studied viscosity-concentration dependence and concentration profiles in vessels with stenosis, and examined non-Newtonian blood flow through arteries and its relationship to stenosis shape. Pulsatile blood flow in arteries, considering vessel characteristics as thin-walled, non-linearly viscoelastic, and incompressible circular shells was also investigated [30,42,48].
