This common chronic disease is known as the “Silent Killer”
HTN
A patient has a BP of 190/122
HYPERTENSIVE CRISIS (>180) or (>120)
If a patient has a SBP of >140 mmHg, but has a NORMAL DBP of <80 mmHg (145/70). What would the patient have?
ISOLATED SYSTOLIC HTN
What is the main goal for HTN management?
GOAL: Maintain BP < 130/80 mm Hg - goal isn't to make their BP perfect but to prevent organ damage!
A patient has a BP reading of 190/122 and has recently STOPPED their medications. What could this patient have?
HTN CRISIS! but which one???
- depends on if the patient has any symptoms.
1. HTN URGENCY (asymptomatic)
2. HTN EMERGENCY (symptomatic)
(SBP >180mmHg and/or DBP >120mmHg)
- Abruptly stopping medications CAUSES Rebound Hypertension
What is known as the leading cause for readmission to hospitals?
HTN
How can cuff sizes affect a patient’s BP reading?
TOO LARGE = LOWER BP
TOO SMALL = HIGHER BP of about 10-40 mmHg difference
How do we treat ISOLATED SYSTOLIC HTN?
reduce risk for cardiovascular events (ex. Stroke, MI, and death)
What should ALL PATIENTS do when managing their hTN?
LIFESTYLE CHANGES FIRST (over pharmacological treatment):
Increase exercise
Stress management
Avoid or decrease alcohol intake
Smoking cessation
Promote nutrition (ex. Dash Diet - address both fat and sodium intake)
What is the MAIN GOAL for HTN URGENCY as opposed to HTN EMERGENCY?
GOAL FOR HTN URGENCY:
- MANAGE BP AND PREVENT ORGAN DAMAGE
GOAL FOR HTN EMERGENCY:
- MANAGE BP and REVERSE/TREAT the ORGAN DAMAGE that has already been done
Explain the patho for HTN
A change in one of for of the factors affecting PVR or CO
OR
A problem with the body’s control systems that regulate Blood Pressure (ex. ANS or RAAS)
What information should you provide your patient regarding how to take a blood pressure reading?
DO NOT exercise, drink coffee or smoke 30 minutes before taking BP
DO NOT talk while taking BP
Feet should remain flat on the floor with legs uncrossed
Arm should remain at heart level
What tests do we conduct to RULE OUT UNDERLYING CAUSES AND COMPLICATIONS OF HTN?
Electrocardiogram (ECG/EKG)
Echocardiogram (ultrasound)—visualize size of heart
Urinalysis - look at kidney function
Labs:
BUN & Creatinine
Electrolytes
Lipid Panel
Fundoscopy (eye exam)
What diet should HTN patients implement?
DASH DIET:
Sodium: ≤ 2.3 g/day
Recommend taking away salt shaker or use lemons or other spices (keep in mind any other interactions with medications)
How do we medically manage a HTN URGENCY PATIENT?
1. ORAL DOSES OF INCREASED DOSE
2. FAST-ACTING HTN MEDS (CLONIDINE - lowers bp within 30 minutes)
Assess vital signs frequently
Assess neuro status for signs of stroke
Monitor I&Os for kidney function
A patient has a BP of 135/80
HTN STAGE 1 (130-139) or (80-89)
HTN risk factors
Advanced Age
African American
Genetics/Family history
Stress
Poor diet - too much salt
Diabetes - damage blood vessels
Hypercholesterolemia - damage blood vessels
Increased alcohol use
Smoking or exposure to secondhand smoke
Overweight/obesity
What are some clinical manifestations of HTN?
NONE:
Asymptomatic (“Silent Killer”)
May be difficult for patients to stay on medications because they feel fine
What is the MAIN GOAL for pharmacological treatment for HTN patients?
GOAL:
- DECREASE peripheral resistance
- DECREASE blood volume
- DECREASE strength and rate of myocardial contraction
What clinical manifestations typically appear in a patient undergoing a HTN EMERGENCY (symptomatic as opposed to HTN URGENCY)?
Severe chest pain
Severe HA and blurred vision
Change in mental status (confusion)
N/V
Dyspnea
Severe anxiety
A patient has a BP of 160/90
HTN STAGE 2 (140 or >140) OR (90 or >90)
Secondary HTN is different from Primary HTN due to
SECONDARY HTN HAS AN UNDERLYING CAUSE:
Renal disease - affects blood volume
Endocrine disorders - cortisol or aldosterone ↑ affects RAAS system; tumor in the adrenal gland ↑ epinephrine and norepinephrine → dysregulation of the ANS
Pregnancy - ↑ or worsen BP especially after giving birth
If left UNTREATED, what are some LATE S/S (based on which organ is compromised) that a patient might have?
1st symptom: changes in visual acuity (blurry vision)
Headache
Fatigue
Dyspnea
Edema in lower extremities
Nocturia - attempt to decreased BP by increase urine output at night
Chest pain - sign of MI or severe heart failure
What are FIRST-LINE ANTI-HTN MEDS? and which ones are recommended for BLACK PEOPLE?
1. THIAZIDE DIURETICS (recommended for blacks)
2. ACE-Is
3. ARBs
4. CCBs (recommended for blacks)
- CCB's are NOT recommended as first-line unless they have a a Hx of HF or CAD.
(sometimes beta-blockers like metoprolol)
How do we manage patients with a HTN EMERGENCY?
BP must be lowered within the first hour
IV medication
Continuous slow IV infusion of a beta blocker: Labetalol
Want to keep reducing BP over 24-48 hours
DO NOT RUSH! If patient has constant BP of 160 and it suddenly gets drop to 120, the patient could develop rebound HTN
Vasodilator: Hydralazine or Nitroprusside
