Hypertension lecture Flashcards
Don’t give pt’s 500mg of digoxin it will kill the patient
Hypertensive crisis is an acute condition of very high blood pressure (BP), with either: SBP > ____ mm Hg and/or DBP > mm Hg
SBP>180
DBP >120
The presence of new or worsening end-organ damage differentiates hypertensive emergency from hypertensive urgency
___________ of perfusion is a key physiological concept that explains the pathophysiology of hypertensive crisis
Autoregulation
The affected organs during a hypertensive emergency commonly include: ______
________
_______
Vascular
Kidney
Brain
Eyes
heart
____________does not require rapid (i.e., immediate) BP reduction because the benefit does not outweigh the risk
A more gradual BP reduction over several hours to days is optimal
Hypertensive urgency
Hypertensive urgency is managed by resuming omitted antihypertensive therapy, increasing current doses of antihypertensives, or adding additional agents to achieve control
____________ is a medical emergency that requires acute hospitalization, frequent monitoring, and, in most cases, intravenous (IV) antihypertensive therapy to control BP
Hypertensive emergency
The goal for managing hypertensive emergencies is to prevent additional ________
additonal organ damage
Target BP goals are different than those for chronic treatment of high BP, and the timeframe for achieving goals is determined by the organ systems affected and comorbidities
Despite no clear mortality benefit with the use of IV antihypertensive agents, their use is still the standard of care intended to reduce further organ damage
____________ is a modifiable risk factor that commonly leads to hypertensive crises
Medication nonadherence
organ dysfunction in the setting of extreme BP elevations constitutes a medical emergency
Because acute target organ disease is present, the benefit of rapid BP lowering with IV antihypertensives generally outweighs the risk of potential ischemic complications
The goal of treatment with IV antihypertensives is to prevent worsening organ dysfunction by targeting specific BP goals.
shifts in autoregulation that make intensive BP lowering suboptimal for organ perfusion. Therefore, overly aggressive BP lowering places patients at risk for ischemic complications
gradual lowering of BP with oral antihypertensives in hypertensive urgency.
