What type of BP meds do African Americans NOT respond well to?

Why are Mexican Americans more likely to have HTN? Describe the age difference for Men and Women with HTN? -- Answer ✔✔ African Americans and Latinos > Whites African Americans: earlier onset, more aggressive, more complications, higher mortality, produce less renin Don’t respond to ACE inhibitors (ex: Lisinopril) Mexican Americans are less likely to seek tx, less control, less aware of HTN and tx HTN increased within males until age 64, then it increases with females Describe how BP is regulated by baroreceptors? What happens to the baroreceptors with consistent HTN? -- Answer ✔✔ BP increase > baroreceptors in aortic arch and carotid artery will trigger and inhibit SNS > decrease HR and decrease force of contraction, vasodilation of peripheral arterioles BP decrease > baroreceptors in aortic arch and carotid artery activates SNS > increase HR and increase force of contraction, vasoconstriction of peripheral arterioles Consistent HTN = baroreceptors accept high BP as "normal" = no response and no s/sx How does the vascular endothelium regulate BP? -- Answer ✔✔ single layer of blood vessels that produce vasoactive substances: Nitric oxide: relaxing factor derived from endothelium = vasodilation (decreased SV and decreased BP) Prostacyclin: maintains low arterial tone at rest = vasodilation (decreased SV and decreased BP) Endothelin: produced by endothelium and is an extremely potent vasoconstrictor (increased afterload, increased SV and increased BP) How does the renal system regulate decreased BP (4)? -- Answer ✔✔ decreased BP: renal retention of water and Na (increases vascular volume to increase BP) Renin-angiotensin-aldosterone response: vasoconstriction and retain fluid to increase BP ADH release: retain fluid to increase BP Activate SNS: increase HR and vasoconstriction to increase BP How does the renal system regulate increased BP (3)? -- Answer ✔✔ Increased BP: inhibit SNS = decreased HR and vasodilation to decrease BP Prostaglandin secretion: vasodilation to decrease BP Natriuretic peptides secretion: diuretics to decrease water and sodium (decreased vascular volume to decrease BP)

Leading cause of death globally and in the U.S. Describe the etiology of CAD? -- Answer ✔✔ Atherosclerosis is a major cause of CAD Focal deposits of lipids primarily in the intimal wall of the artery Endothelial injury and inflammation are precursors to atherosclerosis

For elevated triglyceride and cholesterol: decrease saturated fats (red meat, eggs), decrease/eliminate alcohol and simple sugars, increase fatty fish 2X/week (salmon and tuna) Drug Therapy for Lipid control contains 4 drugs classes that do different actions.
