2.2 Methods
After admission, patients with unstable angina were given aspirin +
clopidogrel or ticagrelor, statins, low-molecular-weight heparins, and
the use of ACEI and receptor blockers to prevent secondary coronary
heart disease. Based on this treatment, Nicorandil was intravenously
pumped, and the pumping speeds (2mg/h, 4mg/h and 6mg/h, respectively)
were adjusted according to the patient’s blood pressure. We adjusted
Nicorandil speed in half an hour, and continuously pumped total of 36mg
before stopping the drug. During the treatment, observe the changes in
blood pressure and heart rate of the patients before and after
treatment, and observe whether the effect of Intravenous Nicorandil on
the blood pressure of the patients is concentration-dependent, and
monitor the adverse reactions during the medication.
