Abstract
BACKGROUND
Handgrip strength (HGS) is a potential method to approximate perioperative risk in cardiothoracic surgery patients and correlates well with European System for Cardiac Operative Risk Evaluation (EuroSCORE) values. This study aimed to characterize the functional capacity in preoperative cardiac surgery patients through HGS.
METHODS
This cross-sectional study investigated patients aged 18 years or older. The collected data included surgical risk (EuroSCORE), body mass index (BMI), body composition (electrical bioimpedance), and HGS.
RESULTS
The mean age of the 278 participants was 62.1 ± 11.2 years, of whom 61.5% were male, 43.2% were overweight, and 26.3% were obese. The main types of surgery were myocardial revascularization (50%) and valve replacement (40.6%). HGS values differed between genders in all age groups (P < 0.05) and were approximately 40% lower than reference values for healthy individuals. The values differed with respect to operative risk (P = 0.003) and had a moderate positive correlation with fat-free mass (rs = 0.435, P < 0.001), a moderate negative correlation with fat mass (rs = -0.447, P < 0.001), and weak negative correlations with age (rs = -0.270, P < 0.01) and EuroSCORE (rs = -0.316, P < 0.01).
CONCLUSIONS
The HGS values of preoperative elective cardiac surgery patients were below reference values for healthy individuals, were lower in male patients, were positively correlated with fat-free mass, and were negatively correlated with fat mass, age, and operative risk. Its preoperative use in these patients is an attractive complementary method of risk assessment in clinical practice.
