The purpose of this study is to learn more about different blood cell counts among people from Africa or the Middle East. People from these areas have fewer white blood cells because they don't have a certain red blood cell marker called the Duffy marker. This is normal and not harmful. The goal of this study is to find better blood count ranges for these people to improve their medical care.

Blood Pressure
The purpose of this study is to compare two ways to improve care for non-Hispanic Black patients with high blood pressure. The first way provides care to patients electronically through phone and video visits. The second way is in person, at a doctor's office, the way someone might normally seek care. All patients will receive a cuff to self-monitor their blood pressure at home. We want to see which way would work better.

Multivessel coronary artery disease is a disease that causes blockages in the blood vessels supplying the heart muscle. The purpose of this study is to compare two common heart procedures to see which one works better for this disease. One uses a small tube and balloon to open clogged heart arteries. The other is surgery to go around the clogged parts. The goal is to see which one helps people live longer and feel better.
