BACKGROUND: Left ventricular hypertrophy (LVH) is an independent risk factor for clinical events (CE), and regression of LVH is associated with reduction of cardiovascular risk. However, whether a continuous relationship between reduction of LVH and risk of CE exists has not been investigated. METHODS: Randomized clinical trials evaluating LVH at baseline and reporting quantitative LVH changes and CE, stroke or new onset heart failure) were included. Meta-regression analysis was performed to test the relationship between changes in LVH and incidence of the composite outcome (all-cause death, MI, stroke or new onset heart failure) and between changes of LVH and occurrence of each component of the composite outcome. Analysis of potential confounder variables was also performed. RESULTS: Fourteen trials including 12,809 participants and reporting 2259 events were included. Follow-up ranged from 0.50 to 5years, with mean 1.97±1.50years. Mean age was 62±5years and 52% of patients were women. The composite outcome was significantly reduced by active treatments (OR: 0.851, IC: 0.780 to 0.929, p<0.001), as well stroke (OR: 0.756, IC: 0.638 to 0.895, p<0.001) whereas MI and new onset heart failure were not significantly reduced by treatments. LVH changes did not predict the reduction of CE. No significant influence on the association of baseline patients and studies characteristics was found. CONCLUSIONS: A significant continuous relationship between LVH changes and CE could not be demonstrated in hypertensive patients, independently on the technique or drug used. Ad hoc designed studies should further explore the relationship between LVH modification and outcomes in hypertensive patients.
