Level of Accelerometer-assessed Preoperative Physical Activity and Short Term Outcome After Elective Cardiac Surgery

2019-10-30 14:03:39 | BioPortfolio


Short term morbidity after elective cardiac surgery remains significant. Standard predictive models, considering simple patient demographics and clinical parameters, show limited efficiency in individual operative risk assessment. There is growing evidence about daily physical activity as a relevant indicator of preoperative "frailty". Although cardiopulmonary exercise testing remains a gold standard, we are looking for more simple tools in order to identify patients with poor physical condition. Accelerometry may be an objective and reproductible method to measure physical activity at patient's home.


The aim of this study is to compare accelerometer-assessed preoperative physical activity between two groups of patients with different postoperative length of stay following elective cardiac surgery. In the future, accelerometry could be used to identify patients that may benefit from prehabilitation programs including exercise therapy before elective cardiac surgery.

Medical and Biotech [MESH] Definitions

Occlusion of the outflow tract in either the LEFT VENTRICLE or the RIGHT VENTRICLE of the heart. This may result from CONGENITAL HEART DEFECTS, predisposing heart diseases, complications of surgery, or HEART NEOPLASMS.

Diseases characterized by pathological irregularities in the HEART CONDUCTION SYSTEM. They may be associated with other heart diseases and syndromes (e.g., BRUGADA SYNDROME; NEUROMUSCULAR DISEASE, HEART BLOCKS), isolated or may result from injuries. You can have a conduction disorder without having an arrhythmia, but some arrhythmias arise from conduction disorders. OMIM: 601144.

Diseases of long duration and generally slow progression. The four main types of noncommunicable diseases are CARDIOVASCULAR DISEASES (e.g., heart attacks and stroke), CANCER, chronic respiratory diseases (e.g., CHRONIC OBSTRUCTIVE PULMONARY DISEASE and ASTHMA) and DIABETES MELLITUS.

Pathological conditions involving the HEART including its structural and functional abnormalities.

A voluntary organization concerned with the prevention and treatment of heart and vascular diseases.
