Clinical Practice Guidelines Hypertension NR 511 Differential Diagnosis and Primary Care 19 June 2019

Pathophysiology • Hypertension is considered the condition when the blood flows through the blood vessels with a force greater than normal. • Hypertension can strain the heart, damage blood vessels, and increase your risk of heart attack, stroke, kidney disease, and death. • Hypertension ... is caused by increases in cardiac output or total peripheral resistance, or both. There is many factors affecting cardiac output and peripheral resistance which include genetics and physiologic mechanisms. • Cardiac output is increased by any condition that increases heart rate or stroke volume, whereas peripheral resistance is increased by any factor that increases blood viscosity or reduces vessel diameter.
