Efficacy
Exploratory
Pragmatic
Not applicable
1. comparison the numbers of episode(times/week) or the consumption of the short-acting nitrates (tablets/week) between before and after of treatment
2. Efficacy rate: Evaluate 2 treatment groups each by following five degree. 1) well improved, 2) improved, 3) less improved, 4) no change, 5) deterioration, 6) impossible to judge, after consideration following subjects, such as number and severity of episodes, consumption of short-acting nitrates, and total impression, together in each group.
3. Improvement of 24 hours electrocardiogram: (When the measurement was carried out in an institution) Evaluate 2 treatment groups each by following 3 degree. 1) improved, 2) no change, 3) deterioration, 4) impossible to judge, after consideration following subjects, such as number of ST rising, maximum degree of ST rising, or continuance time of ST rising, together in each group.
4. entire improvement: after consideration of #2 and #3, evaluate both treatment groups by following five degrees, and compare both groups
1) well improved, 2) improved, 3) less improved, 4) no change, 5) deterioration, 6) impossible to judge
5. About above end-points of #1 to #4, compare both treatment groups according to a patient background

Benidipine administration group: administrate a Benidipine 4mg tablet twice a day after breakfast and supper. The dose can be changed according to the symptom
Nifedipine administration group: administrate a nifedipine 40 mg tablet after supper. The dose can be changed according to the symptom but maximum dose should be 60mg/once/day
