OBJECTIVE: The aim of the present study was to assess the behavior of cardiovascular variables during an in-hospital cardiovascular rehabilitation program in patients following myocardial revascularization surgery. METHODS: A total of 14 patients (mean age: 55.4 ± 6.4 years, 78.6% male) participated in the study, all of whom had a previous diagnosis of coronary insufficiency and indication for elective surgery. The protocol consisted of a group of low-impact (2-3 METs) upper/lower extremity and walking exercises performed both pre and post-operatively (3rd and 4th days). The following variables were evaluated at rest and following the exercise program: heart rate (HR, bpm); systolic arterial pressure (SAP, mmHg); diastolic arterial pressure (DAP, mmHg); mean arterial pressure (MAP, mmHg); double product (DPr, bpm/mmHg); and the Rating of Perceived Exertion (RPE) scale. RESULTS: There was a significant increase in HR and DPr in the individual analysis (P
