Can a common blood pressure drug boost exercise in stented heart patients?

This study looked at whether amlodipine, a blood pressure medicine, can help people with stable angina (chest pain) who already have stents but still have narrowed arteries. About 211 participants took amlodipine or no calcium-channel blocker for 9 months. The main goal was to see if exercise capacity improved, and secondary goals included reducing the need for emergency nitroglycerin. The study is complete and was conducted at teaching hospitals in Korea.
