Systemic chronic inflammation, represented by hypersensitive C-reactive protein (hsCRP), is an essential contributing factor to hypertension. However, the influence of hsCRP levels on the effect of antihypertensive pharmacological therapy remains unknown. We evaluated hsCRP levels in 3756 newly diagnosed, untreated hypertensive subjects. Participants were grouped by tertiles of hsCRP and were randomly treated with nitrendipine + captopril, nitrendipine + spironolactone hydrochlorothiazide + captopril, and hydrochlorothiazide + spironolactone. Blood pressure (BP) was recorded every 2 weeks. A multivariate mixed linear model was used to evaluate the impact of baseline hsCRP levels on the continuous antihypertensive effect. After 3, 6, 9, and 12 months of continuous antihypertensive treatment, no significant difference was observed in BP decline among the different hsCRP groups. We identified interactions between baseline hsCRP levels and follow-up time. After adjusting for conventional risk factors and the interactions between hsCRP and follow-up time, there was no significant association between baseline hsCRP level and antihypertensive effects at 0-6 months of follow-up. However, from 6 to 12 months, subjects with higher baseline hsCRP levels exhibited a more marked BP-lowering effect ( P < 0.001 at 9 months, P = 0.002 at 12 months). Overall, there exist interaction effects between baseline hsCRP levels and follow-up time. Individuals with higher baseline hsCRP levels may exhibit a better response to antihypertensive therapy.
