Abstract
Exercise-based cardiac rehabilitation, an effective and safe adjuvant treatment recommended to patients with coronary artery disease, is scarcely applied to patients with refractory angina (RA) due to difficulties related to safety, trainning prescription and their clinical management. This case report presents an instance of a “no-option” patient with RA, who was included in a 12-week exercise program, in sessions consisted of 40 minutes of treadmill aerobic exercise, three times a week, and intensity prescribed between ischemic/angina threshold and ventilatory threshold 1, obtained in the cardiopulmonary exercise test; mild to moderate angina was allowed during training. Furthermore, 15 minutes of moderate-intensity resistance training (large group muscle exercises, two sets of 8 to 12 repetitions) was performed. At the end of the protocol, the patient presented an important improvement in functional performance (VO 2 peak 17.0 ml/kg/min to 27.3 ml/kg/min), angina threshold (HR 68 bpm to 95 bpm), and intensity chest pain (levels 7 to 5) with no clinical adverse events during the period. Exercise-based cardiac rehabilitation was safe, even in the occurrence of angina/ischemia during training, according to tolerability to symptoms and other warning clinical signs.
