The effect of exercise training on the heart rate recovery (HRR) response to submaximal effort was examined in 81 patients during 12 weeks of phase II cardiac rehabilitation. Although HRR after submaximal effort was relatively reduced in older patients with heart disease and in women, its increase during exercise training in men and women of all ages was consistent with enhancement of parasympathetic tone during activities of daily living.

    • "Carter et al. (2001) found no difference between men and women, and this result was confirmed in some population-based studies (Cole et al., 1999; Vivekananthan et al., 2003). On the other hand, Hao et al. (2002) and Kligfield et al. (2003) found a faster HRR in female participants of a cardiac rehabilitation programme when compared with their male counterparts, and Mahon et al. (2003) reported a faster HRR in girls than in boys after submaximal, but not after maximal exercise. These inconsistencies may be related, at least in part, to the different Figure 1 Phases of heart rate (HR) recovery. "

    • "In line with the present study, in-hospital cardiac rehabilitation for IHD patients had been associated with significantly improved exercise capacity (10-12). Previous studies, however, were based on heterogeneous populations including ACS and stable angina patients (6, 13), while the present study included ACS patients only. "

    ABSTRACT: Recent studies have suggested a favorable effect of cardiac rehabilitation (CR) on patients with cardiovascular disease. This study aimed to evaluate the impact of home-based exercise training with wireless monitoring on acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). A total of 55 ACS patients undergoing PCI were randomly divided into home based exercise training with wireless monitoring cardiac rehabilitation (CR, n = 26) and usual care (UC, n = 29). Exercise capacity and quality of life (QOL) were evaluated at baseline and after 12 weeks. Change of metabolic equivalent of the tasks, maximal exercise time and QOL were significantly increased (+2.47 vs +1.43, P = 0.021; +169.68 vs +88.31 sec, P = 0.012; and +4.81 vs +0.89, P = 0.022, respectively), and the change of submaximal rate pressure product, and of submaximal rate of perceived exertion were significantly decreased (-28.24 vs -16.21, P = 0.013; and -1.92 vs -1.62, P = 0.018, respectively) in the CR group compared to the UC group after 12 weeks. CR using home-based exercise training with wireless monitoring led to improvement of exercise capacity and QOL relative to conventional care in ACS patients undergoing PCI. Our findings suggest that early scheduled CR may be considered in ACS patients undergoing PCI.

    • "We hypothesized that higher levels of vital exhaustion and type D personality would be associated with decreased HRR-1 in patients with CHF. We further predicted that these associations would be independent of previous correlates of reduced HRR, namely female gender [25], increased age [25] [26], impaired left ventricular ejection fraction (LVEF) [5] [27], and reduced exercise capacity [26] [28]. A number of epidemiological studies suggest both a gradual and categorical relationship between reduced HRR and increased cardiovascular risk [29]. "

    ABSTRACT: Vital exhaustion and type D personality previously predicted mortality and cardiac events in patients with chronic heart failure (CHF). Reduced heart rate recovery (HRR) also predicts morbidity and mortality in CHF. We hypothesized that elevated levels of vital exhaustion and type D personality are both associated with decreased HRR. Fifty-one patients with CHF (mean age 58+/-12 years, 82% men) and left ventricular ejection fraction (LVEF) < or = 40% underwent standard exercise testing before receiving outpatient cardiac rehabilitation. They completed the 9-item short form of the Maastricht Vital Exhaustion Questionnaire and the 14-item type D questionnaire asking about negative affectivity and social inhibition. HRR was calculated as the difference between heart rate at the end of exercise and 1 min after abrupt cessation of exercise (HRR-1). Regression analyses were adjusted for gender, age, LVEF, and maximum exercise capacity. Vital exhaustion explained 8.4% of the variance in continuous HRR-1 (p=0.045). For each point increase on the vital exhaustion score (range 0-18) there was a mean+/-SEM decrease of 0.54+/-0.26 bpm in HRR-1. Type D personality showed a trend toward statistical significance for being associated with lower levels of HRR-1 explaining 6.5% of the variance (p<0.08). The likelihood of having HRR-1 < or = 18 bpm was significantly higher in patients with type D personality than in those without (odds ratio=7.62, 95% CI 1.50-38.80). Elevated levels of vital exhaustion and type D personality were both independently associated with reduced HRR-1. The findings provide a hitherto not explored psychobiological explanation for poor cardiac outcome in patients with CHF.
