Efficacy of CPET Combined with Systematic Education of Cardiac Rehabilitation After PCI: A Real-World Evaluation in ACS Patients

Abstract

Introduction: There are scarce real-world data on the long-term efficacy and safety of cardiopulmonary exercise testing (CPET) combined with the systematic education of cardiac rehabilitation (CR) approach for patients postcoronary stenting, which is, therefore, the subject of this study. Methods: Data collected between 1 April 2015 and 20 May 2017 from 11,345 patients in the rehabilitation center database at our hospital were retrospectively analyzed. Five hundred thirty-six patients with incomplete information, or unable to cooperate with telephone follow-up, were excluded; 4001 patients received the combined CR approach; and 6808 patients received only routine post-procedure education (controls). Of these, 2805 CR participants (CR group) were matched 1:1 to controls (control group) using propensity scores. The main outcome was quality of life in Seattle Angina Questionnaire (SAQ) scores. SAQ was measured in hospital and at follow-up; meanwhile, volume/type of habitual exercise, major adverse cardiovascular event (MACE), and its components of target vessel revascularization, myocardial infarction, and cardiac death were recorded and analyzed. Results: At median 583 (range 184-963) day follow-up, compared with controls, the CR group showed fewer patients not engaging in physical exercise (22 vs. 956, p \ 0.05); more cumulative exercise time (h/week) (8.22

Daily exercise improves the long-term prognosis of patients with acute coronary syndrome

“…The follow-up was performed in 1, 3, 6, 12, 24, 36, 48, and 60 months to record the outcome, until the patient's first MACE occurred or the study was terminated by the follow-up on August 31, 2022. The exercise-related indicators were also collected during the follow-up ( 25 ). The exercise intensity was categorized as mild (< 3 METs), moderate (3–6 METs), and high intensity (>6 METs) ( Supplementary eTable 1 ).…”
