Why the study?
Do hyperventilation and mental stress reduce coronary blood flow velocity and produce chest pain in patients with syndrome X?
Do hyperventilation and mental stress reduce coronary blood flow velocity and produce chest pain in patients with syndrome X?
Hyperventilation and mental stress can provoke chest pain and reduce coronary blood flow velocity in patients with syndrome X, likely due to increased microvascular resistance.
