Abstract

INTRODUCTION: Several blood inflammatory markers, such as high-sensitivity C-reactive protein (hs-CRP), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), are linked to increased risk for cardiovascular diseases. This study aimed to evaluate these inflammatory markers after cardiac rehabilitation (CR) in patients with unstable ischemic heart disease (UIHD) who underwent successful percutaneous coronary intervention (PCI). METHODS: A cohort of 115 patients with successful PCI due to UIHD enrolled in the study from January 2018 to March 2021. We used a permuted block stratified randomization technique (2 : 1 ratio). Seventy-seven patients were randomized to the CR group and 38 patients to the control group. The CR group underwent a 12-week pre-specified CR regimen. Blood samples were taken at baseline and follow-up at 12 weeks for both groups. RESULT: Among the 115 patients, 33 patients were female. The mean age was (53 ± 5.55 years) in the control and (53 ± 6.09 years) in the CR group. The two groups were comparable regarding their baseline characteristics and the values of the inflammatory markers. By contrast, at 12 weeks, the inflammatory marker values were significantly lower in the CR group compared to the control group; hs-CRP: 0.11 [0.08-0.14] vs. 0.21 [0.19-0.21], P -value <0.001; NLR: 2.17 [1.42-2.43] vs. 2.26 [2.07-2.6], P -value: 0.016; PLR: 91.2821 [63.3333-103.2000] vs. 92.600 [84.6154-110.0000], P -value: 0.027. CONCLUSION: CR after PCI in UIHD patients may attenuate some inflammatory markers, which might benefit cardiovascular health. Further studies are required to evaluate these findings with longer follow-up and the powered to measure major cardiovascular event rates. Copyright © 2023 Wolters Kluwer Health, Inc.
