conferenceObject Cardiac rehabilitation in patients with refractory angina: preliminary results(2019) DOURADO, L.; ASSUMPCAO, C. R. A. A.; JORDAO, C. P.; VIEIRA, M. L. C.; GOWDAK, L. H. W.; CESAR, L. A. M.; MATOS, L. D. N. J.- Does Myocardial Injury Occur After an Acute Aerobic Exercise Session in Patients with Refractory Angina?(2022) MONTENEGRO, Carla Giuliano de Sa Pinto; DOURADO, Luciana Oliveira Cascaes; JORDAO, Camila Paixao; VIEIRA, Marcelo Luiz Campos; ASSUMPCAO, Camila Regina Alves; GOWDAK, Luis Henrique Wolff; PEREIRA, Alexandre da Costa; NEGRAO, Carlos Eduardo; MATOS, Luciana Diniz Nagem Janot deBackground: It is unclear whether exercise is safe in patients with more advanced forms of coronary artery disease, such as those with refractory angina (RA). Objective: We aimed to determine the effect of an acute aerobic exercise session (AAES) on high-sensitivity cardiac troponin T (hs-cTnT) levels in patients with RA. Methods: This was a longitudinal, non-randomized, and non-controlled clinical study. Participants were recruited from April 2015 to January 2019. On a visual pain scale from 0 to 10, pain rated up to 3 was considered as the top level allowed to continue exercising. We assessed hs-cTnT at baseline and 3 hours after the AAES. The protocol consisted of 5 minutes of warm-up, 30 minutes of continuous aerobic exercise at heart rate corresponding to the anaerobic threshold or angina threshold obtained in the cardiopulmonary exercise testing, and 5 minutes of cooling down. P values less than 0.05 were considered statistically significant. Results: Thirty-two patients with RA were included (61 +/- 9 years, 59.4% male). The baseline hs-cTnT concentration was 10.9 ng/L (95% confidence interval: 9.1 to 13.0 ng/L).The hs-cTnT collected 3 hours after the AAES was 11.1 ng/L (95% confidence interval: 9.1 to 13.5 ng/L). No difference occurred in hs-cTnT before and after AAES (p = 0.657). Conclusions: A single AAES performed at the angina threshold with corresponding visual pain scale did not alter hs-cTnT in patients with RA, suggesting that no significant myocardial injury was elicited by exercising and that this exercise protocol can be considered safe.
- In the Cardiac Rehabilitation Era, is There a ""No-Option"" Refractory Angina Patient?: A Case Report(2023) DOURADO, Luciana Oliveira Cascaes; JORDAO, Camila Paixao; ASSUMPCAO, Camila Regina Alves; MATOS, Luciana Diniz Nagem Janot deExercise-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 (VO2 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.
