A Study of LY3322207 in Healthy Participants and in Participants With Hypertension (High Blood Pressure)

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to investigate the safety of the study drug known as LY3322207. Participants must be healthy or must have hypertension (high blood pressure). Participants with hypertension may already be taking a common drug to reduce blood pressure called an angiotensin-converting enzyme inhibitor (ACE-I) or an angiotensin II receptor blocker (ARB).
