“…Autonomic nervous system improvement may explain it [24,43,44]. The average increase of SBP peak should be 50% of the resting value and an insufficient increase has been associated with left ventricular systolic dysfunction [45]. Nevertheless, the relationship between SBP response and V O 2 peak is unclear.…”

Background and Objectives: To analyze the effects of aerobic, resistance, and combined training on peripheral and central components related to cardiorespiratory capacity after HTx. Materials and Methods: No time restriction was applied for study inclusion. MEDLINE/PubMed; EMBASE, CENTRAL, and PEDro databases were investigated. Studies reporting heart transplanted patients older than 19 years following aerobic, resistance, and combined training according. The outcomes included: V′O2 peak, VE/V’CO2 slope, heart rate (HR peak), systolic and diastolic blood pressure (SBP and DBP peak), maximum repetition test(1RM), sit-to-stand test, and flow-mediated dilation (FMD). The studies were selected by consensus. Four hundred ninety-two studies initially met the selection criteria. Cochrane handbook was used for abstracting data and assessing data quality and validity. Independent extraction by two observers was applied. Results: Isolated aerobic training leads to a greater increase in V′O2 peak than combined training compared to the control group (p < 0.001, I2 = 0%). However, no significant differences were found in the subgroup comparison (p = 0.19, I2 = 42.1%). HR peak increased similarly after aerobic and combined training. High-intensity interval training (HIIT) was better than moderate continuous intensity to increase the V′O2 after long term in HTx. Still, there is scarce evidence of HIIT on muscle strength and FMD. No change on VE/V’CO2 slope, FMD, and SBP, DBP peak. 1RM and the sit-to-stand test increased after resistance training (p < 0.001, I2 = 70%) and CT (p < 0.001, I2 = 0%) when compared to control. Conclusions: Aerobic and combined training effectively improve VO2 peak and muscle strength, respectively. HIIT seems the better choice for cardiorespiratory capacity improvements. More studies are needed to examine the impact of training modalities on VE/V’CO2 slope and FMD.

“…By use of dobutamine, Bellotti et al 28 have reported normal contractility in transplanted patients with no rejection; however, in the presence of rejection, contractility was reduced 29 , suggesting that dobutamine echocardiography could aid in correlating with episodes of rejection.…”

“…Left ventricular function, evaluated through the Doppler echocardiogram, consists of the filling and emptying of the left ventricle, which determines the LVEF (%) and consequently translates the ability of the left ventricle to eject blood into the aorta during systole. 38 The LVEF (%) involves both the final systolic volume (FSV) and the final diastolic volume (FDV), with values ≥55% (Teicholz method) being considered normal for healthy adults. 38 In cardiac transplant patients there is a reduction in systolic volume at rest and during exercise, when compared to healthy individuals.…”

Considering the benefits of aquatic physiotherapy and the need for a well structured and differentiated rehabilitation for individuals submitted to HT, the aim of this study was to evaluate the cardio respiratory effects of an aquatic physiotherapy exercise program in a young adult after HT. Case characteristics This female volunteer was 38 years of age and had undergone a heart transplant in February 2016 due to dilated peripartum cardiomyopathy, in the Clinical Hospital (CH) of Belo Horizonte. Two months after the HT, the subject was referred to the University of Itaúna Integrated Physiotherapy Clinics (CIFUI), located in Itaúna MG, to initiate Cardiovascular soil Rehabilitation for six months. After this period, due the particularly rare case and the benefits of water based exercises, this volunteer was invited to participate in this study. Materials and methods Methods The study was approved by the Research Ethics Committee of the University of Itaúna, under authorization No. 1.843.378. The evaluations and the exercise program were carried out in the CIFUI.

A elevação da pressão arterial sistólica durante o teste ergométrico após transplante cardíaco: correlação com o quadro clínico e a função ventricular avaliada pela ecocardiografia sob estresse com dobutamina

Abstract: Unlike other populations, no correlation was found between delta SBP during exercise testing and clinical condition or left ventricular function in heart transplant patients. Pathophysiological factors associated with delta SBP reduction during exercise testing remain unknown.
