Hypertension Flashcards
Cardiloogy I
HTN Facts
> Most Common Reason for a visit to PCP
Most Widely recognized treatable risk factor for other comorbidities such as ( CVT, PVD, CKD, CHF, Retinopathy)
Untreated or poorly controlled, doubles the risk of CKD, CVA, PVD……..
Heart disease leading cause of death Men and Women.
__________________________________________________
Summary: > Common Visis
> Treabable Risk Factor for other commorbidies
Unreated and poorly controlled
Leasing cause of death
HTN Epidemiology
116 million people in the US have HTN : 50 % not taking medications.
> Age 55: 90% chance of having HTN the patient is 55 yrs old : Prevalence increase with age
> 75% of those with HTN are not at goal <130/80
> Affects 20 to 30% of African Americans
> Affects 10 to 15% of Caucasians .
> Heart diseases most common cause of death word wide men and women
HTN: Primary vs
90% Do Not have a single reversible cause
Primary or Essential
Plethora of risk factors
people having HTN just because
HTN : Secondary
10% have identifiable mechanism
Remove the problem, fix the high BP
Secondary HTN
HTN: Risk Factors
> No clear cause, generally linked to genetics, poor diet, lack of exercise, obesity ( 9 factors)
Age: onset age 25 to 55
Obesity > 24.5
NSAIDs
Cigarette smoking
Alcohol use > 2 drinks a day
OSA ( sleep apnea )
Increase Na+ intake
Genetic and Environmental Factors
Metabolic Syndrome
Metabolic Syndrome
Also Call Syndrome X : have to meet 3 outo 5 criteria to dx Metabolic Syndrome:
- Abdominal Obesity
- Elevated Triglyceride ( >/= 175)
- Low HDL (below 40)
- Increase BP (130/80)
- FG >100
HTN: Clinical Manifestations
> Light -Headedness
Visual Disturbances
Headaches ( Pulsation, Suboccipital headache)
Retinal Changes ( Hypertensive Retinopathy)
Auscultate S4 ( Left Ventricle Hypertrophy) stiffness of heart that can lead to Diastolic CHF
HTN most common cause of Left Venticul Hypertrophy Leading to Diastolic CHF
HTN Complications
> Vascular damage
Heart Failure
CVA (hemorrhagic/ischemic stroke )
Renal disease
Aortic Dissection
Development of atherosclerosis
Normal BP
Less than 120 AND
Less than 80
Elevated BP
120-129 AND
Less than 80
HTN Stage I
130-139 OR
80-89
Stage 2
140 or Higher OR
90 or Higher
Hypertension Crisis
Highter 180 and /or
Highter 120 DBP
Consult cardiologist
start interventions eventhougth it’s first BP as such
HTN
> /= 130 or
/= 80
Isolated SBP
> 130 SBP or Highter
DBP <80
Isolated DBP
DBP <130
DBP >80
Mix HTN
130/80 or More
Atherosclerotic Cardiovascular Disease (ASCVD)
Risk Enhancers
> Family Hx of CAD
Persistent Elevated LDL >/=160 OR TG >/= 175
CKD
Metablic Syndrome
Inlfammatory Disease ( RA, Cirrhois, HTN)
Ethnicity ( South Asian’s )
DM
HTN Initial Work Up
Labs Diagnostics

CBC EKG
CMP Echo
Lipid Panel Stress Test
FGM or A1C
TSH
UA ( protein?)
Uric Acid
HTN: Lifestyle Modifications : Approx SBP
> Weight Reduction (BMI 18.5 to 24.9)
Q 10 lbs: 5 to 20 mmHg
Dash diet: : 8-14 mmHg
Na+ Reduction ( less 2.4gm/day) 2 to 8 mmHG
**Physcial Activity : 4 to 9
Moderation of alcohol consumption 2drink/day
smoking cessation
Stress Reduction
HTN RX of Choice Primary Agents Non Aftrican American
Thiazides 1st then with or without
ACE Inhibitors
ARBs
CCB (dihydrophyridines )
CCB (nondihydropyridines )
Pimary for African American
Thiazides or CCB 1st
Thiazides
> 1st line
Monitor Electrolytes
Hydrochlorothiazide (HCTZ); Chlorthalidone; Metolazone ( Strong meds can cause HypoNatremia)
ACE Inhibitors
” Pril” “ you give ACE in APRIL”
> Benazepril, Captopril, Lisininopril
> Monitor Renal Function
> Cough and Angioedema
