| 實物特徵: | Purpose: To examine predictors of walking distance (WD) following exercise-based cardiac rehabilitation (CR) program in hypertensive cardiac patients. Methods: Volunteers were 224 (174 males and 50 females) patients (age = 61.1 ± 10.8 yr.). Before and after the CR program, the 6-min walking test (6MWT) distance and hemodynamic variables were measured. Predictors of 6MWT distance following CR were studied by the Automatic Linear Modeling (LINEAR) procedure in IBM SPSS Statistics, version 24. Model criteria for LINEAR were standard use auto data, confidence level 95%, and forward stepwise criteria model with Akaike’s Information Criterion Corrected (AICC). Statistics for the LINEAR model included the predictor coefficient (Pc), relevance (Rel = 0 to 1.0) and significance (p). The predictors studied were gender, age, number of risk factors, CR sessions, baseline values of body weight, body mass index, waist circumference (WC), resting heart rate (HR), resting systolic blood pressure (SBP), resting diastolic blood pressure (DBP), rate pressure product (RPP), mean arterial pressure (MAP), 6MWT, and recovery 6MWT HR, SBP, DBP, RPP, MAP, and 5-min HR recovery, SBP, DBP, RPP, and MAP. Results: Patients underwent 33.3 ± 4.8 (min = 20, max = 37) exercise sessions. Between-gender compliance to exercise sessions was similar (males = 33.5 ± 4.6 vs. females = 32.7 ± 5.5; p = 0.339), and both genders improved the 6MWT distance after CR (males = 119.4 ± 70.1 m, females = 98.3 ± 67.1 m, p < 0.001). Significant predictors of 6MWT distance model (R2 = 0.63) were the baseline 6MWT (Pc = 0.53, Rel = 0.58, p < 0.001), age (Pc = -2.25, Rel = 0.16, p < 0.001), dummy-transformed gender (Pc = -45.02, R = 0.10, p < 0.001), 5-min recovery SBP (Pc = -0.86, Rel = 0.05, p = 0.001), WC (Pc = -1.12, Rel = 0.04, p = 0.002), recovery DBP (Pc = 1.22, Rel = 0.04, p = 0.003), and the number of CR sessions (Pc = 1.64, Rel = 0.02, p = 0.031). CONCLUSION: The increase in 6MWT distance in male and female cardiac hypertensive patients following ~33 CR sessions was explained mainly by baseline 6MWT, age, gender, hemodynamic and adiposity variables. Following CR, males achieved more distance than females in the 6MWT. |
