2 ACE Inhibitor MI Mortality Trials
Broad (short term) CONSENSUS II GISSI-3 ISIS-4 Chinese-Cap Selective (higher risk, long term) SAVE (EF £ 40%) AIRE (clinical HF) SMILE (anterior MI, no lytic) TRACE (wall motion score, EF £ 35%) Angiotensin-converting enzyme inhibitors or ACE inhibitors are of proven clinical value in a broad spectrum of patients with cardiovascular disease. With over one hundred thousand patients with acute myocardial infarction enrolled in placebo-controlled randomized trials, a clear survival benefit was demonstrated with the use of ACE inhibitors. The relative and absolute benefits of ACE inhibitors were most pronounced when administered long-term to patients selected for higher risk based on LV dysfunction and/or clinical signs of acute heart failure.

The survival advantage occurred early and increased to approximately 60 lives saved per thousand treated with long-term therapy. In this meta-analysis, ACE inhibitor use reduced the odds ratio for death by approximately 26%. With over 1500 deaths, the confidence intervals were narrow and the results considered sufficiently robust so that no further placebo-controlled trials are warranted Flather MD, et al.

The benefits were observed early after the start of therapy and persisted long term. The benefits of treatment on all outcomes were independent of age, sex, and baseline use of diuretics, aspirin, and beta-blockers. The use of ACE inhibitors in these patients was also associated with important reductions in the risk of major nonfatal CV events, such as hospital admission for the management of heart failure and experiencing a recurrent myocardial infarction. Indeed, in the meta-analysis with over 2200 events, there was a 25% reduction in the risk of death, non-fatal MI or heart failure in those randomized to an ACE inhibitor as compared to placebo plus conventional medical therapies.

5 Renin-Angiotensin Aldosterone System
Non-ACE Pathways (e.g., chymase) Vasoconstriction Cell growth Na/H2O retention Sympathetic activation Angiotensinogen AT1 renin Angiotensin I Angiotensin II ACE Angiotensin-receptor blockers, or ARBs, provide an opportunity to inhibit the renin-angiotensin system directly at the angiotensin II type 1 receptor level, which has been postulated to provide more complete inhibition of the deleterious effects of angiotensin. Alternatively, because ACE inhibitors (kininase II inhibitors) also reduce bradykinin breakdown, the combination of an ACE inhibitor plus an ARB may result in incremental clinical benefits. These assumptions must be rigorously tested as direct comparisons of these three modes of inhibiting the renin-angiotensin system to provide the quantitative data needed to guide clinical practice.

6 Aims VALIANT was designed as a mortality trial in high-risk MI
patients (SAVE, AIRE, TRACE) who derived particular benefits from an ACE inhibitor. To determine whether: the ARB valsartan was superior to captopril in improving survival and with equal statistical power the addition of the ARB valsartan to captopril was superior to the proven dose of captopril in improving survival VALIANT was designed as a mortality trial in high-risk MI patients who derived particular benefits from an ACE inhibitor (SAVE, AIRE, TRACE). To determine whether, the ARB valsartan was superior to captopril in improving survival, and, with equal statistical power, to determine whether, the addition of the ARB valsartan to captopril was superior to the proven dose of captopril in improving survival. If valsartan was not superior to captopril, a non-inferiority analysis was prespecified to determine whether valsartan could be considered “as effective as” captopril in improving survival. Am Heart J;2000;140: If valsartan was not superior to captopril, a non-inferiority analysis was prespecified to determine whether valsartan could be considered “as effective as” captopril

7 ACE-I Comparator MI Trial
MI Trials with Mortality Benefit Early Use Long-Term GISSI 3 lisinopril SAVE captopril ISIS 4 captopril AIRE ramipril Chinese-Cap captopril TRACE trandolapril Captopril—most extensively studied with survival benefits in both early initiation and long-term trials Captopril was chosen as a comparator because it was the most studied ACE inhibitor with the most extensive proof of clinical benefit. No head to head trial has previously shown a benefit or “as good as” captopril. Two prior direct ARB-ACE-I comparisons to captopril (50 mg tid) showed a trend for fewer deaths and major CV events with captopril therapy.

8 double-blind active-controlled
Acute MI (0.5–10 days)—SAVE, AIRE or TRACE eligible (either clinical/radiologic signs of HF or LV systolic dysfunction) Major Exclusion Criteria: — Serum creatinine > 2.5 mg/dL — BP < 100 mm Hg — Prior intolerance of an ARB or ACE-I — Nonconsent double-blind active-controlled Captopril 50 mg tid (n = 4909) Valsartan 160 mg bid (n = 4909) Captopril 50 mg tid + Valsartan 80 mg bid (n = 4885) Patients with acute MI (12 hours to 10 days), complicated by either clinical and/or radiologic signs of heart failure and/or LV dysfunction (radionuclide EF less than 40 % or echocardiographic EF less than or equal to 35%) were eligible. Major exclusions were persistent cardiogenic shock, systolic blood pressure less than 100 mmHg, serum creatinine above 2.5 mg/dl, prior intolerance to an ACE inhibitor or ARB, unwillingness to provide consent. This was an active therapy trial with no placebo and all comparisons are made against the captopril group. Consenting patients were randomized in a 1:1:1 manner to either captopril using the SAVE regimen - target of 50 mg, t.i.d; valsartan – target to 160 mg b.i.d.; or the combination captopril (SAVE regimen) plus valsartan target to 80 mg b.i.d.  The primary end point was all-cause mortality and the trial was designed to be event driven. Other important end points were CV death, hospitalization for heart failure and recurrent MI. Safety and tolerability were assessed and compared. The median duration of follow-up in VALIANT was 24.7 months.

The point estimate for valsartan compared to captopril, as stated, was 1.00 and, importantly, the lower limit of the 97.5% confidence interval was well within the non-inferiority range-- P = (one-sided UCL 1.094) A per protocol population of 14,285 patients that had all received study medication and met stricter cardiac-marker-based-inclusion criteria for myocardial infarction was also conducted to provide another validation of the non- inferiority test. The criteria for non-inferiority were, again, well satisfied in this more restricted population – P=0.002 (one-sided UCL 1.085).In VALIANT, the per-protocol population analysis was important for the non-inferiority analysis, since it was more stringent.

Hazard Ratio for Mortality Combined TRACE SAVE AIRE Valsartan preserves 99.6% of mortality benefit of captopril. With the proven survival value of ACE inhibitors in these high-risk MI patients, our evaluation of valsartan was against active therapy rather than placebo. An estimate of the effectiveness of valsartan, as compared to that of an imputed placebo, was derived by the methods of Fisher, Hasselblad and Kong. We estimated that valsartan had an effect that was 99.6% of that of captopril (the 95% confidence interval: 60 to 139%.)

0.4 Captopril Valsartan Valsartan + Captopril 0.3 Probability of Event 0.2 Since ACE inhibitors have been shown to reduce the risk of heart failure admissions and nonfatal MIs, as well as death, we compared the hazard ratios for this composite event of the valsartan groups to the proven captopril regimen. The event rate for the valsartan monotherapy group was similar to captopril with a hazard ratio of The combination of valsartan plus captopril was also no different than captopril alone with a hazard ratio of 0.97.

For each of the CV fatal and nonfatal composites, the point estimates favored valsartan and, importantly, the lower limit of the 97.5% confidence intervals were well within the non- inferiority range. Specifically, with over 3000 composite events, the hazard ratio and confidence intervals for valsartan relative to captopril demonstrates that all of these cardiovascular benefits of captopril were preserved in the valsartan group.

0.4 Captopril Valsartan * Valsartan + Captopril * 0.3 Overall 0.2 Probability of Event Discontinuation of study medications increased as a function of time in all groups. Relative to captopril patients, the valsartan group was less likely to discontinue due to an adverse event attributed to study medication. In contrast, those on the combination therapies were more likely to discontinue their study medication and more likely to experience study drug-related reasons for this discontinuation.

Combining therapies resulted in additive adverse experiences. Pfeffer, et al., NEJM 2003;349: 1 0.5 Hypo- Renal Hyper- Cough Skin Taste Angio- tension Causes kalemia Rash Disturbance edema n =

29 Conclusion In patients with MI complicated by heart failure, left
ventricular dysfunction or both: Valsartan is as effective as a proven dose of captopril in reducing the risk of: Death CV death or nonfatal MI or heart failure admission Combining valsartan with a proven dose of captopril produced no further reduction in mortality—and more adverse drug events. Implications: In these patients, valsartan is a clinically effective alternative to an ACE inhibitor. In patients with MI complicated by heart failure, left ventricular dysfunction or both, valsartan is as effective as a proven dose of captopril in reducing the risk of: Death, CV death, or nonfatal MI, or hospital admission for heart failure. Combining valsartan with a proven dose of captopril produced no further reductions in mortality and resulted in more adverse drug events. Implications are that by preserving all the cardiovascular benefits of an ACE inhibitor in this population, valsartan is a clinically effective alternative for high risk patients post-MI.
