HTN Flashcards
What is hypertension
1)Increased vascular resistance
2)Volume expansion
3)Imbalance between basil constriction and basal dilation forces
4)RAAS plays a role
What is hypertension
1)Increased vascular resistance
2)Volume expansion
3)Imbalance between vasoconstriction and vasodilation forces
4)RAAS plays a role
Risk factors for hypertension
Obesity
High salt intake
Physical inactivity
Long term impact of RAAS activation
Vascular remodeling: thickening/narrowing of blood vessel walls
What consistent blood pressure is considering diagnostic for HTN
> 130/80
Primary(essential) HTN
90-95% of cases
No identifiable cause
Graduate onset, typically influenced by lifestyle and genetics
Bp rises gradually over time
Secondary HTN
1)5-10% of cases
2)Caused by an identifiable medical condition or medications
3)Sudden onset
4)May present with very high BP(>180/120)
