What I propose to do in the next hour Put Atherosclerosis in context of RISK FACTORS,
especially HTN & DYSLIPIDEMIA.
Review the pathobiology of HTN, HTN Tx/Rx, and how to design effective, well tolerated, and affordable therapy
Review the pathobioloby of DYSLIPIDEMIA, lipid lowering Tx/Rx, and how to design well tolerated, and affordable therapy
This hour can not cover all the details; familiarize yourself with good reviews [JNC 7/8, NCEP 3/4]

For persons over age 50, SBP is a more important than DBP as CVD risk factor.
Starting at 115/75 mmHg, CVD risk doubles with each increment of 20/10 mmHg throughout the BP range.
Persons who are normotensive at age 55 have a 90% lifetime risk for developing HTN.
Those with SBP 120–139 mmHg or DBP 80–89 mmHg should be considered prehypertensive who require health-promoting lifestyle modifications to prevent CVD.
New Features and Key Messages
Slide Source:Lipids Online Slide Librarywww.lipidsonline.org
HYPERTENSION AND CARDIOVASCULAR DISEASE RISK
HTN prevalence ~ 50 million people in the United States.
The BP relationship to risk of CVD is continuous, consistent, and independent of other risk factors.
Each increment of 20/10 mmHg doubles the risk of CVD across the entire BP range starting from 115/75 mmHg.
Prehypertension signals the need for increased education to reduce BP in order to prevent hypertension.

Benefits of Lowering BP
Average Percent Reduction
Stroke incidence 35–40%
Myocardial infarction 20–25%
Heart failure 50%
Slide Source:Lipids Online Slide Librarywww.lipidsonline.org
Office BP Measurement
Use auscultatory method with a properly calibrated and validated instrument.
Patient should be seated quietly for 5 minutes in a chair (not on an exam table), feet on the floor, and arm supported at heart level.
Appropriate-sized cuff should be used to ensure accuracy.
At least two measurements should be made. Consider ABI
Clinicians should provide to patients, verbally and in writing, specific BP numbers and BP goals.
Slide Source:Lipids Online Slide Librarywww.lipidsonline.org
Patient Evaluation
Evaluation of patients with documented HTN has three objectives:
1. Assess lifestyle and identify other CV risk factors or concomitant disorders that affects prognosis and guides treatment.
2. Reveal identifiable causes of high BP. [95-98 % will be “Essential”]
3. Assess the presence or absence of target organ damage and CVD.
Slide Source:Lipids Online Slide Librarywww.lipidsonline.org
Laboratory Tests Routine Tests
• Electrocardiogram • Urinalysis • Blood glucose, and hematocrit • Serum potassium, creatinine, or the corresponding estimated
GFR, and calcium• Lipid profile, after 9- to 12-hour fast, that includes high-
density and low-density lipoprotein cholesterol, and triglycerides
Optional tests • Measurement of urinary albumin excretion or
albumin/creatinine ratio
More extensive testing for identifiable causes is not generally indicated unless BP control is not achieved
Slide Source:Lipids Online Slide Librarywww.lipidsonline.org
Easily Identifiable (“Primary”) Causes of Hypertension
High Sodium Diet ………….[Use of salt shaker and convenience
foods, high urinary sodium] Sleep apnea………………………….……..….[Obesity, typical Sx] Drug-induced or related causes………………[BCP, NSAIDs, etc] Chronic kidney disease ………...…..[CC< 60cc/min, Proteinuria] Primary aldosteronism ……………………..………[Hypokalemia] Reno vascular disease……..…. [Abdominal bruit in m.a. woman] Coarctation of the aorta…….. [Widened radial-pedal pulse inter- val; measure pedal systolic BP. ABI>1]

*Treatment determined by highest BP category.†Initial combined therapy should be used cautiously in those at risk for orthostatic hypotension.‡Treat patients with chronic kidney disease or diabetes to BP goal of <130/80 mmHg.

Goals of Therapy
Reduce CVD and renal morbidity and mortality.
Treat to BP <140/90 mmHg or BP <130/80 mmHg in patients with diabetes or chronic kidney disease.
Achieve SBP goal especially in persons >50 years of age.
However, do not lower Diastolic BP < 60 mmHg to protect Coronary Perfusion

Algorithm for Treatment of Hypertension
Not at Goal Blood Pressure (<140/90 mmHg) (<130/80 mmHg for those with diabetes or chronic kidney disease)
Initial Drug Choices
Drug(s) for the compelling indications
Other antihypertensive drugs (diuretics, ACEI, ARB, BB, CCB)
as needed.
With Compelling Indications
Lifestyle Modifications
Stage 2 Hypertension (SBP >160 or DBP >100 mmHg)
2-drug combination for most (usually thiazide-type diuretic and
ACEI, or ARB, or BB, or CCB)
Stage 1 Hypertension(SBP 140–159 or DBP 90–99 mmHg)
Thiazide-type diuretics for most. May consider ACEI, ARB, BB, CCB,
or combination.
Without Compelling Indications
Not at Goal Blood Pressure
Optimize dosages or add additional drugs until goal blood pressure is achieved.
Consider consultation with hypertension specialist.

Step-wise therapy to control Essential Hypertension
Outline DIET and LIFE-STYLE therapies that patient can reasonably begin and maintain.
Encourage DASH diet and HBPM
Begin Rx with ACE-I (e.g. LISINOPRIL 10-20 mg) or ARB (e.g. LOSARTAN 25-50 mg) or Diuretic (Chlorthalidone 12.5 mg)
Add D-CCB (e.g. Amlodipine 5 mg)
Slide Source:Lipids Online Slide Librarywww.lipidsonline.org
Escalating therapy in Essential Hypertension
Next add low dose diuretic (e.g. Chlorthalidone 12.5-25 or HCTZ 12.5- 25 mg) Use loop diuretic if edema, CHF, or KKD present: (e.g. Furosemide 20-40 mg QD-BID)
Next uptitrate ACE-I and/or D-CCB to full dose
(e.g. Lisinopril 40 mg and Amlodipine 10 mg)
Next add vasodilator-BB (e.g. Carvedilol 6.25 mg BID)
Uptitrate all Rx to full dose and/or add Spironalactone

Causes of Resistant Hypertension
1. Excess dietary sodium intake (Diet must be < 2 Grams Sodium)2. Medication prescription issues a. Inadequate diuretic therapy b. Inadequate doses of vasodilator meds c. Drug actions and interactions (e.g., nonsteroidal anti-inflamm.
drugs (NSAIDs), cocaine, sympathomimetics, oral contraceptives) d. Non-adherence (Not refilling Rx or not taking Rx)3. Excessive alcohol intake (Often >5 oz/day)4. Obesity, esp. Abnormal Sleep Breathing/Obstructive Sleep Apnea5. Primary causes of HTN (KKD, B RAS, Pheo, Aldost, Coarct, etc) Circulation 2008;117:e510-526

• T-Chol/HDL ratio remains the single • best predictor of risk on lipid profile Example: T-C=200 HDL-C=50 T-C/HDL= 4

Atherosclerosis in Diabetes~80% of all diabetic mortality– 75% from coronary atherosclerosis and/or CHF– 25% from cerebral or peripheral vascular
disease>75% of all hospitalizations for diabetic complications>50% of patients with newly diagnosed type 2 diabetes have CHD
Most common cause of ESRD and Blindness which are micro-vascular diseases.
DM-2 is as much or more a Vascular Disease as a Metabolic Disease.

• Cigarette smoking cessation
• Blood pressure control
• Lipid management to goal
• Physical activity
• Weight management to goal
• Diabetes management to goal
• Antiplatelet agents / anticoagulants
• Renin angiotensin aldosterone system blockers
• Beta blockers
• Influenza vaccination
