Choosing the Right Treatment:
Medications, Stenting, or Surgical Intervention
Tony NguyenBio-Engineering
Removing wastes from the body Release of certain hormones Helps control blood pressure
What does a kidney do?
The main artery to the kidney Carries oxygen and nutrients
Renal Artery
Artery Blockage Pressure drop Kidney is fooled Induces the Renin-Angiotensin Mechanism Overall increase in blood pressure & volume
What happens in a stenosis?
Medications ◦ ACE inhibitors, beta blockers, ARB inhibitors◦ Blocks the renin-angiotensin mechanism
Different Treatments
Stenting◦ Improve blood flow
Different Treatments
Surgical Intervention◦ Associated risks
Different Treatments
3 months: prescreening & b.p. tests 3 months: diagnosis & b.p. tests 1 year: medications & b.p. tests 1 year: stenting & b.p. tests 1 year: surgery & b.p. tests
Experimental Design
Two kinds of patients◦ >> 140/90 mmHg (Group I)◦ ≈ 140/90 mmHg (Group II)
Improvement◦ Group I gets to140/90 mmHg◦ Group II gets to 130/85 mmHg◦ Everything else is a failure
Threshold for Improvement
Stenting will be the most effective◦ It should reduce medications◦ Not as risky◦ Not as time consuming
Hypothesis
Reduce errors Reduce unnecessary risks Reduce costs Reduce time
Why is this important?

…a Better Place!
