  thumb|240px|right|enalapril 3d structure enalapril (marketed as vasotec in the usa, enaladex in some other countries, and enacard for veterinary useenacard listed at http://www.drugs.com.) is an angiotensin-converting-enzyme (ace) inhibitor used in the treatment of hypertension, diabetic nephropathy, and some types of chronic heart failure. ace converts the peptide hormone angiotensin i to angiotensin ii. one of the actions of angiotensin ii is the vasoconstriction of blood vessels, resulting in an increase in blood pressure. ace inhibitors such as enalapril prevent this effect. enalapril has been shown to lower the death rate in systolic heart failure.{{cite journal | title =clinical practice: systolic heart failure | journal =n engl j med | date =january 21, 2010 | author =john j.v. mcmurray | volume =362 | issue =3 | pages =228â238 | url =http://www.nejm.org/doi/full/10.1056/nejmcp0909392 | doi =10.1
