Abstract

Current guidelines lack sufficient evidence to recommend a specific blood pressure lowering strategy to prevent cardiovascular disease after preeclampsia. We conducted a double-blind cross-over trial to identify the most potent antihypertensive strategy: renin-angiotensin-aldosterone system (RAAS) inhibition (losartan), sympathoinhibition (moxonidine), low sodium diet and placebo (n = 10). Due to low inclusion rate our study stopped prematurely. Initiatory analyses showed no significant effect of antihypertensive strategy on office blood pressure and 24-hour blood pressure. However, nocturnal dipping was significantly higher on RAAS inhibition and low sodium diet compared to placebo and sympathoinhibition. Optimal cardiovascular prevention after preeclampsia should be further explored.
