Fluid analysis links magnetic fields and stenosis shape to harmful pressure changes in weak hearts.
A computational fluid dynamics model demonstrates the effects of magnetic fields and stenosis shape on blood flow parameters.
Hypothesis-generating only from computational model; clinical studies needed before considering magnetic field effects on weak hearts.
Fluid flow analysis of blood flow through multi stenosis arteries in the presence of magnetic field is investigated. In this paper the effect of magnetic field and shape of stenosis on the flow rate, pressure gradient, wall shear stress and resistance parameter is studied. The blood flowing through the artery is considered to be Newtonian. This model is consistent with the principles of Ferro hydrodynamics and magneto hydrodynamics (MHD). The results indicate that rise in systolic pressure and fall in diastolic pressure are very harmful for weak heart.

Verma et al. (2009) studied blood flow through multi stenosis arteries. magnetic field and shape of stenosis was evaluated on flow rate, pressure gradient, wall shear stress and resistance parameter. Fluid flow analysis indicates that a rise in systolic pressure and fall in diastolic pressure due to magnetic field and stenosis shape are very harmful for a weak heart.
