Figure 1 Response to AI (1011M to 3 x 106M) in arteries from patients with CHF in the presence of vehicle, enalaprilat, chymostatin or both chymostatin and enalaprilat. AI = angiotensin I; CHF = chronic heart failure; KPSS = Krebs solution with KCl substituted for NaCl on an equimolar basis.

Figure 2 Response to AI (1011M to 3 x 106M) in arteries from patients with CHD in the presence of vehicle, enalaprilat, chymostatin or both chymostatin and enalaprilat. AI = angiotensin I; CHD = coronary heart disease. KPSS = Krebs solution with KCl substituted for NaCl on an equimolar basis.
