Quality of Life Is Improved 1 Year After Cardiac Surgery

Background: Quality of life (QoL) is increasingly important in the era of patient-centered outcomes and value-based reimbursement. However most follow-up is limited to 30 days, and long-term data on QoL improvement associated with symptom relief are lacking. Therefore we sought to analyze QoL after cardiac surgery in a nonemergent, all-comers population.

Methods: Four hundred two patients undergoing routine cardiac surgery at 2 large urban hospitals in the Dallas, Texas area were enrolled. Follow-up was complete for 364 patients. Data were collected from August 2013 to January 2017. The Kansas City Cardiomyopathy Questionnaire was administered at baseline, 1 month, and 1 year after surgery. Repeated-measures analysis was used for each domain of the questionnaire for all procedures and stratified by procedure. If time was found to be a significant factor, pairwise analysis was performed with P values adjusted using the Tukey-Kramer method.

Results: There was a significant increase across all domains of Kansas City Cardiomyopathy Questionnaire scores for all procedures and for most domains when stratifying by procedure. This increase in QoL was most marked after 1 month. All domain scores increased through 1 year except symptom stability, which peaked at 1 month postsurgery and then regressed at 1 year, suggesting an overall improvement and stabilization of symptoms. The occurrence of complications did not alter this trajectory.

Conclusions: QoL and other patient-centered outcomes are improved at 1 month and continue to improve throughout the year. Knowledge of these data is important for patient selection, fully informed consent, and shared decision-making.
