Effects of minocycline on parameters of cardiovascular recovery after cardioplegic arrest in a rabbit Langendorff heart model.


:Pharmacological cardiac organ protection during cardiopulmonary bypass presents an opportunity for improvement. A number of different strategies have been established to minimize ischemia/reperfusion-induced damage to the heart. Among these, cardioplegia with histidine-tryptophan-ketoglutarate solution and hypothermia are the most frequently used regimens. The antibiotic minocycline has been used in this context for neuroprotection. The aim of the current study was to evaluate whether the application of minocycline prior to cardioplegia exerts a protective effect on cardiac muscle. For this purpose, this study investigated six rabbit hearts with minocycline treatment (1 μmol/L) and six without in a Langendorff model of 90 min cold cardioplegic arrest using Custodiol followed by a 30 min recovery phase. Histological analysis of cardiac muscle revealed that markers of apoptosis, oxidative and nitrosative stress were significantly lower in the minocycline group, whereas adenosine triphosphate (ATP)- and malondialdehyde (MDA)-levels and O2-consumption were not affected by minocycline. Functionally, recovery of dP/dt (max) and dP/dt (min) was significantly faster in the minocycline group than in control. This leads to the conclusion that adding minocycline to the cardioplegic solution may improve left ventricular recovery after cardioplegic arrest involving reduced pro-apoptotic effects.
