Direct vasodilators
Angiotensin inhibitors
Calcium channel blockers
What are the two classes of angiotensin inhibitors
Angiotensin-converting enzyme inhibitors (ACE)

What do angiotensin inhibitors do?
Prevent vasoconstriction and sodium and water retention
ACE inhibitors often have which side effect that causes people to swith to an ARB?
Coughing
Main side effects with HTN meds?
Orthostatic hypertension
Sexual dysfunction
Tachycardia (vasodilators and angiotensin inhibitors)
What time of day is BP the highest?
Shortly after waking
(Take 24hr meds early in the morning)
The failure to reach goal BP in patients who are adhering to full doses of a an appropriate 3 drug therapy regimen that includes a diuretic?
Resistant hypertension
How is orthostatic HTN defined?
Decrease of 20 or more in SBP,
Decrease of 10 or more in DBP

AND/OR

Increase of 20 beats or more in pulse
(when going from supine to standing)
A severe and abrupt elevation in BP, arbitrarily defined as a DBP greater than 140 is?
Hypertensive crisis
Who is most likely to experience hypertensive crisis?
HTN patients who are not complying with meds or who are undermedicated
A hypertensive emergency is often manifested as?
Hypertensive encepholapathy syndrome including:

HA
Nausea
Vomiting
Seizures
Confusion
Stupor
Coma
What is a good indicator of the seriousness of hypertensive crisis?
Association of BP and target organ damage (not just BP alone)
How quickly do you want to lower BP in a patient with hypertensive crisis?
Over 24 to 48 hours in a stable patient
(some seriously bad shit can happen if BP is lowered too fast)
What is the most effective IV drug for the treatment of hypertensive crisis?
Sodium nitroprusside
Abnormal clinical condition that results in physiologic changes of vasoconstriction and fluid retention
Heart Failure
HF is associated with what cardiovascular diseases?
HTN
CAD
MI
HF is the most common reason for hospital admission in?
Adults over 65
Primary risk factors for HF?
CD and advancing age (primary)

(HTN, DM, obesity, smoking and serum lipids also risk factors)
What is the most common cause of HF?
Systolic failure, which results in the inability of the heart to pump blood
What is the hallmark of systolic dysfunction?
Decrease in the left ventricular ejection fraction
The impaired ability of the the ventricles to relax and fill?
Diastolic failure
The diagnosis of diastolic failure is made on the basis of the presence of?
Pulmonary congestion
Pulmonary HTN
Ventricular hypertrophy
(and a normal ejection fraction)
