Predictors of the short-term effect of Isoleucine-Proline-Proline/Valine- Proline-Proline lactotripeptides from casein on office and ambulatory blood pressure in subjects with pharmacologically untreated high-normal blood pressure or first-degree hypertension

摘要

Our aim was to evaluate the predictors of Isoleucine-Proline-Proline/ Valine-Proline-Proline (IPP-VPP) lactotripeptides (LTPs) antihypertensive effect in the context of a short-term large double-blind randomized clinical trial involving 164 pharmacologically untreated subjects in primary prevention for cardiovascular disease. When compared with the baseline, office systolic blood pressure (SBP) (-3.42 mm Hg, P < .001) and diastolic blood pressure (DBP) (-2.35 mm Hg, P < .001) significantly decreased, in the LTP-treated patients only. No significant change in predictors during the study of ambulatory blood pressure measurement (ABPM) parameters was observed. A short-term supplementation with LTPs significantly improves the office SBP and DBP, especially in male subjects. The main predictor of LTP antihypertensive effect was the baseline BP.
