  2. VALUE: Primary Hypothesis In hypertensive patients at highcardiovascular risk, for the same level of blood pressure control, valsartan will be more effective than amlodipine in reducing cardiac morbidity and mortality Julius S et al. Lancet. June 2004;363.

  3. VALUE: Blood Pressure Changes From Baseline to the End of the Study 0 –5 SBP DBP mmHg –10 –15 –20 Valsartan-Based Regimen Amlodipine-Based Regimen Julius S et al. Lancet. June 2004;363.

  24. VALUE: Main Results Good BP control was achieved with both treatment regimens, but BP decrease in the amlodipine group was more pronounced, particularly early in the trial Despite blood pressure differences, the primary composite cardiac endpoint was not different between the treatment groups Julius S et al. Lancet. June 2004;363.

  25. VALUE: Other Results • There was no difference in all cause death between the two groups • Incidence of non-fatal MI was significantly lower in the amlodipine group • Incidence of stroke was lower, but not significantly, in the amlodipine group • There was a positive trend in favour of valsartan for less heart failure but this did not reach significance • There was a highly significant lower rate of new-onset diabetes in the valsartan group Julius S et al. Lancet. June 2004;363.

  26. VALUE: Interpretations • VALUE is the first trial to show a lower rate of new-onset diabetes when an ARB (valsartan) was compared to a CCB (amlodipine) • Long-term implications and mechanisms of this important finding deserve further investigation Julius S et al. Lancet. June 2004;363.

  27. VALUE: Interpretations • The observed difference in stroke rates appears to be strongly related to differences in achieved BPs • The benefits of valsartan in heart failure prevention emerged later in the study when BP differences were smaller, indicating that there is a potential beneficial effect of valsartan beyond BP control Julius S et al. Lancet. June 2004;363.

  28. Our results provide an important lesson about the design, conduct, and analysis of future trials in hypertension VALUE shows the importance of analysisof data at time-specific intervals over the course of a trial VALUE: Implications Julius S et al. Lancet. June 2004;363.

  29. VALUE: Conclusions • Prompt BP control in hypertensive patients at high cardiovascular risk is very important • The between-group differences in heart failure and diabetes suggest that valsartan may offer benefits beyond BP control Julius S et al. Lancet. June 2004;363.
