Considering cardiopulmonary rehabilitation intensity is often setting by heart rate clinically, and only few study focused on exercise responses patients with CAD, the purposes of this study were to compare blood pressure responses of the same target heart rate on different exercise modes in patients with CAD and to compare the effects of blood pressure responses after exercise training.~This is a crossover trial study. The investigators will recruit 30 subjects with CAD who are referred to phase II cardiopulmonary rehabilitation exercise training. After at least 3 times of familiar with the cardiopulmonary rehabilitation training machine, the subjects performed the treadmill or stationary bicycle and exercise to personalized target heart rate for 10 minutes, take a rest until the heart rate recover to the resting heart rate, and then repeated the exercise in another exercise mode. The test order will be random. After at least 12 times of cardiopulmonary rehabilitation training, the test will be performed again.
