Objective: Cardiac transplant is the last alternative therapy for patients suffering from end stage heart failure. It aims to manage these patients to have bigger hemodynamic improvement and better quality of life. Although functional capacity is caught up post-cardiac transplant (TX), some physiological responses remain reduced and become even more decrease with the use of medicaments. Nevertheless, there are few trials comparing people at different post-cardiac transplant terms according to their cardiorespiratory responses. This paper aims to evaluate and compare cardiorespiratory data of people at different post-cardiac transplant terms.

Material/Methods: 21 post-Tx patients (8 women) were divided into two groups according to their Tx- term. G1 was defined as long-term Tx, with ≥6 years post-Tx, n=10, age of 51.5±14.6 years, BMI 28.3±11.2 kg/m2 and LVEF 62.7±3.5 %; G2 as short-term Tx, with ≤ 3 years post-Tx, n=11, age of 41±15.2 years, BMI 25.3±4.7 kg/m2 and LVEF 67±4.4 %. All patients were submitted to a cardiorespiratory test performed on a treadmill. Their hemodynamic data, heart rate (HR), systolic and diastolic blood pressure (SBP and DBP) were evaluated at rest, peak exercise and recovery, and, the cardiorespiratory one, at peak exercise.

Results: Hemodynamic data showed no significant difference between G1 and G2 respectively, with HR at rest (beats/min) 93.9±7.1 vs. 97±11, HR at peak exercise (beats/min) 130.6±13.5 vs. 128.4±19; SBP at rest (mmHg) 130.2±24.8 vs. 122.7±1.3; SBP at peak exercise (mmHg) 155.6±29.4 vs. 146±35.4; SBP at 1st min of recovery (mmHg) 154.2±32.5 vs. 143.7±28.9; DBP at rest (mmHg) 86.9±12 vs. 84.2±8.6; DBP at exercise peak (mmHg) 75.1±14.6 vs. 70.3±12.8; and DBP at 1st min of recovery (mmHg) 80.9±11.7 vs. 74.8±10. No significant difference was also observed between G1 and G2 for exercise test duration (min): 13.3±3.4 vs. 14.2±3.1 and for cardiorespiratory data: peak VO2:(ml/Kg/min) 21.4±3.4 vs. 22.9±4.4; slope VE/VCO2: 28.6±4.0 vs. 28.6±3.2 and VE: (L/min) 33.7±4.4 vs. 35.1±2.3.

Conclusion: Neither short nor long term transplantation has influence on physical capacity of cardiac recipients.
