Role of Microrheology of Blood (Hyperviscosaemia)
Hyperviscosity of blood, due to either of the blood subphases (with single exception of plasma viscosity) may lead to transient and reversible ischaemic episodes which may cause ventricullar fibrillation and cardiac arrest. Viscosity factors (hyperviscosity) can mimic coronary occlusion due to atherosclerosis or can mimic coronary vasospasm (or be the cause of the latter) and can be responsible for the onset of myocardial infarction, be it symptomatic or asymptomatic and silent. Thus, the clinical manifestations of ischaemic heart disease may largely depend on the presence and severity of abnormal Theological factors that transiently and acutely (but probably with accelerating amplitude and frequency) interfere with the coronary flow and myocardial perfusion.
