Myocardial ischemia and heart attack

/in /by

Myocardial ischemia and heart attack may arise from cocaine abuse because……. a. it increases oxygen demand (by inhibiting reuptake of norepinephrine at adrenergic nerve endings in the heart) and can increase oxygen supply by causing vasodialation b. it decreases oxygen demand (by stimulating reuptake of norepinephrine at adrenergic nerve endings in the heart) and can reduce oxygen supply by causing vasospasm

c. it increases oxygen demand (by inhibiting reuptake of norepinephrine at adrenergic nerve endings in the heart) and can reduc oxygen supply by causing vasospasm

d. it increases oxygen demand (by inhibiting reuptake of norepinephrine at adrenergic nerve endings in the heart) and can increase oxygen supply by causing vasospasm
