AIM: Cardiac and renal diseases are common disorders that frequently coexist. We tested the hypothesis that the levels of circulating endothelial-derived apoptotic microparticles (EDA-MPs; CD31(＋)CD42b(-)AN(-)V(＋)) and platelet-derived apoptotic microparticles (PDA-MPs; CD31(＋)CD42b(＋)AN(-)V(＋)) are useful biomarkers for predicting the presence of cardiorenal disease (CRD).
METHODS: A total of 68 patients with chronic kidney disease (CKD) and angina pectoris (CKD-AP) undergoing cardiac catheterization were prospectively enrolled into group 1, 10 patients with coronary artery disease (CAD) without CKD were enrolled into group 2 (CAD(＋)CKD(-)) and 10 patients without CAD and CKD were enrolled into group 3 (CAD(-)CKD(-)).
RESULTS: The serum creatinine levels were significantly higher, whereas the estimated glomerular filtration rates (eGFRs) were significantly lower, in group 1 than in the other two groups (all p < 0.02). The circulating levels of EDA-MPs and PDA-MPs did not differ between the patients with and without CKD (all p > 0.2). However, the circulating levels of EDA-MPs and PDA-MPs were significantly higher in group 2 than in groups 1 and 3 (all p < 0.03). In addition, differences were noted in the circulating EDA-MP and PDA-MP levels between groups 1 and 3, although without statistical significance (all p > 0.09). Meanwhile, among the CKD patients, the subgroup analysis showed that the levels of MPs were significantly higher in those with CAD than in those without (all p=0.001), while a multivariate analysis demonstrated that CAD was the only factor independently predictive of high levels of circulating EDA-MPs and PDA-MPs (p=0.033).
CONCLUSIONS: The link with increased circulating levels of MPs is more consistent in patients with CAD than in those with CKD.
