Abstract:
Objectives: This study aims to determine the protective effect of cilostazol on myocardium in
obese Wistar rats with induced ischemia-reperfusion injury (IRI).
Methods: Four groups with 10 Wistar rats were included: 1] Sham Group: IRI was not established in
normal weight-Wistar rats. 2] Control Group: IRI but no cilostazol in normal weight-Wistar rats. 3]
Cilostazol in normal weight-Wistar rats: IRI and cilostazol was administered. 4] Cilostazol in obese-
Wistar rats: IRI and cilostazol was administered.
Results: Tissue adenosine triphosphate (ATP) levels were significantly higher and superoxide dismutase
(SOD) levels significantly lower in the control group than in the sham group and normal weight cilostazol
group (p=0.024 and p=0.003). Fibrinogen levels were 198 mg/dL in the sham group, 204 mg/dL in
the control group, and 187 mg/dL in the normal-weight cilostazol group (p=0.046). Additionally, plasminogen
activator inhibitor-1 (PAI-1) levels were significantly higher in the control group (p=0.047).
The level of ATP was significantly lower in the normal-weight cilostazol group than in the obese group
(104 vs 131.2 nmol/g protein, p=0.043). PAI-1 level was 2.4 ng/mL in the normal weight cilostazol
group and 3.7 ng/mL in the obese cilostazol group (p=0.029). Normal-weight Wistar rats with cilostazol
had significantly better histologic outcomes than the control group and obese Wistar rats (p=0.001 and
p=0.001).
Conclusion: Cilostazol has a protective effect on myocardial cells in IRI models by decreasing inflammation.
The protective role of cilostazol was reduced in obese Wistar rats compared with normal-weight
Wistar rats.
