OBJECTIVE:The aim of this study was to evaluate if there is a relationship between the number of comorbidities, autonomic modulation, and quality of life in patients diagnosed with coronary artery disease. METHODS: A cross-sectional study was conducted at an outpatient rehabilitation center in Presidente Prudente-SP, Brazil. A total of 27 participants (65.33±9.23 years) diagnosed with coronary artery disease were assessed, from a cardiac rehabilitation program, independent of sex or age. The number of comorbidities was evaluated using the Self-Administered Comorbidity Questionnaire, and quality of life was evaluated using the Medical Outcome Study 36-Item Short Form Health Survey (SF-36) (eight domains: functional capacity, physical aspects, pain, general health status, vitality, social aspects, emotional aspects, and mental health). To evaluate the cardiac autonomic modulation, the heart rate was registered beat to beat using an heart rate monitor in the supine position during rest for 30 min. A total of 1000 RR intervals were considered to calculate linear (time domain: RMSSD, SDNN; frequency domain: LF, HF, LF/HF) and nonlinear indices (SD1, SD2, SD1/SD2) of heart rate variability. RESULTS: A negative correlation was observed between the aggregation of comorbidities and the pain domain of the p=0.03). No significant correlations were observed between other variables (p>0.05). CONCLUSION: The number of comorbidities is inversely related to the pain domain of the SF-36, suggesting that a higher pain level is related to a higher number of comorbidities in coronary artery disease patients.

RESUMOO objetivo foi Descrever as atividades desenvolvidas e caracterizar os participantes do Projeto de Reabilitação Cardiovascular no Ritmo do Samba. Estudo descritivo transversal, realizado com 13 mulheres que participam de um grupo de reabilitação por meio do samba. Dados pessoais, medicamentos, fatores de risco (FR) e mensuração de frequência cardíaca (FC), pressão arterial (PA) e medidas antropométricas foram feitas para caracterização. A PA sistólica e diastólica foram de 121,53±20,75 mmHg e 80,76±12,55 mmHg, respectivamente. A FC de repouso de 75,61±9,72 bpm, circunferência de cintura de 96,42±9,34 cm, circunferência de quadril de 109,42±8,15 cm e a relação entre eles de 0,87±0,05 cm. Histórico familiar (N = 10), sedentarismo (N = 8), obesidade (N = 7) e estresse (N = 7) foram os FR mais prevalentes. Conclui-se que a população participante do projeto é exclusivamente feminina, com idade acima de 50 anos e PA dentro da normalidade. Ainda, os principais FR foram o histórico familiar, sedentarismo, obesidade e estresse. Palavras-chave: Reabilitação cardíaca; Fatores de Risco; Dança. CARDIOVASCULAR REHABILITATION PROJECT IN THE SAMBA RHYTHM OF THE PUBLIC UNIVERSITY OF SÃO PAULO STATE ABSTRACTThe objective was to describe the activities developed and characterize the participants of the Cardiovascular Rehabilitation Project in the Samba Rhythm. A descriptive cross-sectional study was carried out with 13 women participating in a rehabilitation group through samba. Personal data, medications, risk factors (RF) and heart rate (HR) measurements, blood pressure (BP) and anthropometric measurements were made for characterization. The systolic and diastolic BP were 121.53 ± 20.75 mmHg and 80.76 ± 12.55 mmHg, respectively. The resting HR of 75.61 ± 9.72 bpm, waist circumference of 96.42 ± 9.34 cm, hip circumference of 109.42 ± 8.15 cm and the relation between them of 0.87 ± 0 , 05 cm. Family history (N = 10), sedentary lifestyle (N = 8), obesity (N = 7) and stress (N = 7) were the most prevalent RF. It has concluded that the majority of the project's participants is exclusively female, with an age over 50 years old and BP within normality. Also, the main RF were the family history, sedentary lifestyle, obesity and stress.
