Preeclampsiacan causea decrease in placental perfusion

Syncope may causeDecreased cerebral perfusion

by poor cardiac output(passive) caused bydecreased arterial perfusion

by inadequate cardiac output during exercise(passive) caused bydecreased myocardial perfusion

prolonged uterine contractions in combination with maternal bearing down efforts(passive) caused byreduced placental perfusion

occurrence related to gestational hypertensioncausesreduced placental perfusion

by inadequate cardiac output(passive) caused bydecreased myocardial perfusion

by a thrombus that has developed on a disrupted atherosclerotic plaque(passive) caused byreduced myocardial perfusion

progressive hypotensioncan leadto decreased coronary perfusion

If untreated decreased blood flow andcan leaddecreased perfusion of the myocardium

A sudden decrease in blood pressurecan causeless perfusion

that women with low weights have an increased risk of fetal growth retardation , which can be explained by an increased rate of vasoconstriction and decreased serum glucose levels due to poor diet and decreased blood pressureprovokingreduced placental perfusion
