Background: Chronic kidney disease is a risk factor for heart failure (HF). Although cystatin C can detect early kidney dysfunction, limited data are available on the association between cystatin C and HF. VSports手机版.

Methods: In a prospective nested case-control study design, we examined whether cystatin C is associated with an increased risk of HF in the PHS and whether such an association is stronger in hypertensive subjects. We selected 220 cases of incident HF and 220 controls, matched on age, year of birth, and time of blood collection. Plasma cystatin C was measured using an immunonephelometry method. We used conditional logistic regression to estimate relative risks (RRs). V体育安卓版.

Results: Compared with the lowest tertile, the multivariable adjusted RR (95% CI) for HF was 1. 15 (0. 69-1. 89) and 1. 78 (1. 01-3. 13) for the second and third tertiles of cystatin C, respectively. Additional adjustment for systolic blood pressure and history of hypertension attenuated this association (RR = 1. 0, 1. 23 [0. 73-2. 09], and 1 V体育ios版. 61 [0. 90-2. 88] from the lowest to the highest tertile, respectively). Furthermore, we observed a 4-fold increased risk of HF in the second and third tertiles of cystatin C among hypertensive individuals and no meaningful effects of cystatin C on HF among nonhypertensive subjects. .

Conclusions: Our data demonstrated that higher levels of cystatin C are associated with an increased risk of HF and that such association may be limited to hypertensive individuals. Additional studies are warranted to further examine the relationship between hypertension and cystatin C on the risk of HF VSports最新版本. .
