Abstract
Abstract Aims The purpose of this subanalysis is to explore whether or not teleprehabilitation leads to worsening cardiac symptoms in patients accepted for coronary artery bypass grafting (CABG). Methods A subgroup of patients accepted for CABG (including off-pump and minimally invasive) who were randomised between teleprehabilitation and standard care in DCC-trial were included. Prehabilitation patients had access to blended care supported by online modules, including nutritional support, functional exercise training, smoking cessation, inspiratory muscle training, and psychological support. All patients were weekly telemonitored for cardiac symptoms using a customized digital platform. Results This cohort included 155 patients. Baseline characteristics, including NYHA and CCS class, were balanced, except for shorter preoperative waiting times in weeks (15.0 [9.8-22.2] versus 12.5 [7.0-16.0]) in the teleprehabilitation group. There was no significant difference in incidence of major adverse cardiac events in the preoperative period. There were 141 patients (77 control; 64 teleprehabilitation) with at least one symptom monitoring entry. A total of 373/1786 (21%) entries indicated worsening of cardiac symptoms. The distribution was right-skewed and did not significantly differ between both groups. There was no statistically significant difference in time to event between control and teleprehabilitation for any cardiac symptom (p = 0.529), angina (p = 0.167), or dyspnea (p = 0.334). Conclusion Teleprehabilitation does not lead to worsening cardiac symptoms prior to CABG. We postulate that teleprehabilitation, which includes low-intensity physical training, can be safely offered to patients undergoing elective CABG.
