African Americans

Developing healthy habits is particularly important among African Americans because they have higher rates of smoking, obesity, diabetes, and salt sensitivity. They are also more likely to incur complications such as stroke or kidney damage as a result of unchecked hypertension. Diuretics work especially well in this population because of their effectiveness in treating hypertension in patients who are salt-sensitive. On the other hand, ACE inhibitors seem to be less effective at low doses when prescribed as a single medication. Ultimately, many African Americans have such severe hypertension that two or more drugs are needed to bring their blood pressure under control.
