Composición corporal y variabilidad del ritmo cardiaco en pacientes con enfermedad pulmonar obstructiva crónica candidatos a rehabilitación respiratoria

Abstract

Body composition is a non-invasive method, which gives us information about the distribution of tissues in the body structure, it is also an indicator of the risk of mortality in patients with chronic obstructive pulmonary disease. The heart rate variability is a technique that gives us information of autonomic physiological condition, being recognized as an indicator which is decreased in a number of diseases. The purpose of this study was to assess body composition and heart rate variability. The methodology used is that of Debora Kerr (1988) endorsed by the International Society for advances in Cineantropometría for body composition and heart rate variability of the guidelines described by the American Heart Association (1996). Roscraff equipment, caliper Slimguide and watch Polar RS 800CX was used., BMI 26.7 ± 3.9 kg / m 2; Muscle Mass 26.1 ± 6.3 kg; Bone Mass 1.3 kg ± 8.1 76 ± 9.9 years Age: 14 candidates for pulmonary rehabilitation patients were evaluated, Adipose mass 16.4 ± 3.6 kg; FEV1 54 ± 14%. Increased waist circumference and waist hip ratio was associated with a lower overall heart rate variability. The bone component was positively related to the variability of heart rate and patients with higher forced expiratory volume in one second had lower highfrequency component in heart rate variability. In these patients, the heart rate variability is reduced globally and is associated with cardiovascular risk parameters.
