What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Guanxin Shutong CapsuleDrug

    3 capsules three times a day; Duration: 4 weeks. Number of Cycles: until progression or unacceptable toxicity develops.

  • Placebo CapsuleDrug

    3 capsules three times a day; Duration: 4 weeks.

  • nitroglycerineDrug

    Adults: 0.25mg-0.5mg (half pill or 1 pill) once, sub-lingual. One more pill per 5 minutes untill pain relief. If total dose is 3 pills in 15 minutes and the pain is still in, please seek medical advice urgently.

    The participators in both arms who have agina symptom will take Nitroglycerine. So the accumulated consumption of participators is the one of the maesuremnts.

    Measured: 6 weeks

  2. Exercise treadmill testing (ETT)

    ST-segment displacement in electrocardiogram: Observe ST-segment displacement of J point after 60ms, including the degree of ST-segment depression.

    Measured: 4 weeks

Secondary outcomes (6)
  1. Usage of nitroglycerine per day (average value)
