“…Only tests with correct HRPC presentation (no outliers or interruptions of HR recordings) and a HR max within 15% of the expected HR max calculated as 210-age were included in our analysis. The test protocol was uniform and independent from age, gender and performance and was applied according to the recommendations of the local Society of Cardiology (22). All ergometer tests started at 20 W and power was increased in uniform 20 W increments per minute up to exhaustion.…”

“…k-values were classified as downward deflection k+ (k > 0.1) (regular), linear k0 (−0.1 ≤ k ≤ 0.1) and upward deflection k-(k < −0.1) (atypical) (Figure 1). Furthermore, P max in percent of age predicted power (%P max ) was calculated using a standard equation (Table 1) from the local cardiological society (22). To assess the effect of performance on HR deflection and HR max we compared subjects with low (P low : 25%-quartile) and high (P high : 75%-quartile) performance (%P max ) within each age group.…”

Introduction: The Heart Rate Performance Curve (HRPC) is neither linear nor uniform and related to ß1-adrenoceptor sensitivity. As aging and exercise influence ß1-adrenoceptors we suggested age, sex and performance effects on the HRPC. Aim of the study was to examine the effects of aging on the deflection of the HRPC in maximal incremental cycle ergometer exercise (CE) in a large cohort of healthy subjects. Methods: Heart rate (HR) data of 2,980 men (51 ± 15 years) and 1,944 women (52 ± 14 years) were classified into age groups (≤20 up to >80 years). We analyzed age and performance (P low 25%-quartile and P high 75%-quartile of age predicted power) effects on HR max and on the degree (k) and the type (regular downward deflection k > 0.1, linear −0.1 ≤ k ≤ 0.1 and atypical upward deflection k < −0.1) of the HRPC. Results: k-values decreased significantly with age in men and women and were significantly higher in women. Atypical HRPC's increased by a linear trend from ≤20 to 70 years (m) respectively 80 years (w) from 10 to 43% (m) and 9 to 30% (w). HR max of all age groups was lower in P low and overall number of atypical HRPC's was 21% (m) and 16% (w) higher compared to P high. Conclusion: Aging increased the number of atypical HRPC's with upward deflection in CE tests, which influences exercise intensity prescription especially when using fixed percentages of HR max. Changes in HRPC's were affected by sex and performance, where women generally and subjects with higher performance presented less atypical HRPC's even at older age.

Exercise Capacity and Functional Performance in Heart Failure Patients Supported by a Left Ventricular Assist Device at Discharge From Inpatient Rehabilitation

et al. 2017

Adequate physical and functional performance is an important prerequisite for renewed participation and integration in self-determined private and (where appropriate) professional lives following left ventricular assist device (LVAD) implantation. During cardiac rehabilitation (CR), individually adapted exercise programs aim to increase exercise capacity and functional performance. A retrospective analysis of cardiopulmonary exercise capacity and functional performance in LVAD patients at discharge from a cardiac rehabilitation program was conducted. The results from 68 LVAD patients (59 males, 9 females; 55.9 6 11.7 years; 47 HVAD, 2 MVAD, 15 HeartMate II, 4 HeartMate 3, and 4 different implanting centers) were included in the analysis. Exercise capacity was assessed using a cardiopulmonary exercise test on a bicycle ergometer (ramp protocol; 10 W/min). The 6-min walk test was used to determine functional performance. At discharge from CR (53 6 17 days after implantation), the mean peak work load achieved was 62.2 6 19.3 W (38% of predicted values) or 0.79 6 0.25 W/kg body weight. The mean cardiopulmonary exercise capacity (relative peak oxygen uptake) was 10.6 6 5.3 mL/kg/min (37% of predicted values). The 6-min walk distance improved significantly during CR (325 6 106 to 405 6 77 m; P < 0.01). No adverse events were documented during CR. The results show that, even following LVAD implantation, cardiopulmonary exercise capacity remains considerably restricted. In contrast, functional performance, measured by the 6-min walk distance, reaches an acceptable level. Light everyday tasks seem to be realistically surmountable for patients, making discharge from inpatient rehabilitation possible. Long-term monitoring is required in order to evaluate the situation and how it develops further. Key Words: Heart failure-Left ventricular assist deviceCardiac rehabilitation-Exercise capacity-Functional performance.In the last few years, left ventricular assist devices (LVADs) have been increasingly implanted as treatment for terminal heart failure (HF). Whereas initially these systems were only used as a bridge to transplantation (BTT), today approximately half of all recipients have them implanted as the ultimate destination therapy (DT) (1).The overriding therapeutic goal of LVAD implantation is to ensure patient survival and guarantee preservation of organ function (2). However, when patients become permanently dependent on the system, a return to everyday life and restoration of an acceptable quality of life acquire crucial significance. An optimum build-up of exercise capacity and adequate functional performance is therefore very significant. Cardiac rehabilitation (CR) can and should make an important contribution in this context (3,4). After being discharged from a CR center the patients should once more become able to autonomously manage the necessary tasks in their everyday lives back home.Over the last few years, several studies have emerged, most of them small, which report results following rehabilitat...

The influence of acute physical effort on liver stiffness estimation using Virtual Touch Quantification (VTQ). Preliminary results.

Aim: Food intake and acutely decompensated cardiac failure may impair liver stiffness estimations, mainly because these methods are influenced by liver blood flow variation encountered in these conditions. It is well known that also during physical effort liver blood flow changes, due to the redistribution of blood flow mainly to the skeletal muscles. The aim of this study is to assess the change of liver shear-wave velocities immediately after cessation of an acute physical effort. A secondary aim was to find the proper timing for accurate liver stiffness estimation after physical exhaustion. Material and methods: Liver shear-wave velocities were measured using virtual touch quantification (VTQ) in seven apparently healthy volunteers, in fasting conditions. All subjects underwent a complete abdominal ultrasound study, including the liver VTQ. Then, all subjects performed a spiroergometry and thereafter, another series of three liver shear-wave velocity measurements were performed: immediately after spiroergometry, five min, and ten min after spiroergometry, respectively. Results: Before spiroergoemetry, the mean liver shear-wave velocity was 1.05±0.12 m/sec. Immediately after spiroergometry, mean liver shear-wave velocities increased significantly, measuring 1.34±0.16 m/sec (p <0.01). The mean liver shear-wave velocities at five and ten minutes after exhausting were 1.23±0.14 m/sec and 1.05±0.11 m/sec respectively. Conclusions: Liver stiffness estimation using VTQ was influenced by acute physical exercise in our study group. Despite the small number of subjects, the preliminary results show that if patients had done physical effort before VTQ elastography, they should rest at least ten minutes before reliable liver stiffness estimations can be performed.
