【解説】ACE阻害薬は左室収縮不全による心不全の経過を改善するため、全症例が適応となる第一選択薬である。SOLVED試験で効果が検証されている。左室駆出力(LVEF)35%以下の非症候性心不全患者にエナラプリルを投与した場合、プラセボと比較して心不全による入院と死亡の発生を有意に低下させた。全死亡と心血管死に関しては有意差は示されなかったが、低下傾向が認められた。

BACKGROUND: It is not known whether the treatment of patients with asymptomatic left ventricular dysfunction reduces mortality and morbidity. We studied the effect of an angiotensin-converting--enzyme inhibitor, enalapril, on total mortality and mortality from cardiovascular causes, the development of heart failure, and hospitalization for heart failure among patients with ejection fractions of 0.35 or less who were not receiving drug treatment for heart failure. METHODS: Patients were randomly assigned to receive either placebo (n = 2117) or enalapril (n = 2111) at doses of 2.5 to 20 mg per day in a double-blind trial. Follow-up averaged 37.4 months. RESULTS: There were 334 deaths in the placebo group, as compared with 313 in the enalapril group (reduction in risk, 8 percent by the log-rank test; 95 percent confidence interval, -8 percent [an increase of 8 percent] to 21 percent; P = 0.30). The reduction in mortality from cardiovascular causes was larger but was not statistically significant (298 deaths in the placebo group vs. 265 in the enalapril group; risk reduction, 12 percent; 95 percent confidence interval, -3 to 26 percent; P = 0.12). When we combined patients in whom heart failure developed and those who died, the total number of deaths and cases of heart failure was lower in the enalapril group than in the placebo group (630 vs. 818; risk reduction, 29 percent; 95 percent confidence interval, 21 to 36 percent; P less than 0.001). In addition, fewer patients given enalapril died or were hospitalized for heart failure (434 in the enalapril group; vs. 518 in the placebo group; risk reduction, 20 percent; 95 percent confidence interval, 9 to 30 percent; P less than 0.001). CONCLUSIONS: The angiotensin-converting--enzyme inhibitor enalapril significantly reduced the incidence of heart failure and the rate of related hospitalizations, as compared with the rates in the group given placebo, among patients with asymptomatic left ventricular dysfunction. There was also a trend toward fewer deaths due to cardiovascular causes among the patients who received enalapril.

背景:無症候性左心室機能不全の患者の治療が死亡率および罹患率を低下させるかどうかは知られていない。我々は、0.35以下の左室駆出力を有する心不全患者において、アンジオテンシン変換酵素阻害剤(ACEーI)であるエナラプリルが、心血管系の原因による全死亡率および死亡率、心不全発症および心不全入院に及ぼす影響を研究した。
