CIMTCarotid Intima Media Thickness

2

What is it?• B-mode ultrasound (cross-

section)• Distal 1 cm of the common

carotid artery far wall• Thickness of the intima and

media combined

3

Atherosclerosis Progression

4

Rationale for CIMT

CAD is leading cause of death in US (25% of all deaths)

Increased CIMT correlates with atherosclerosis progression in coronary and cerebral vessels

Detects disease at early (presymptomatic) stage

Assess early intervention strategies

Improves risk prediction beyond use of traditional risk factors

5

How Results Are Reported

Mean thickness in mm, right and left

Percentile for age and sex

Percentiles >75th indicate increased risk

6

Clinical Use

Most useful in middle age

Most useful for those at intermediate risk–Family history of premature CAD in 1st-degree relative

–Persons <60 with severe abnormality of a single risk factor

–Women <60 with at least 2 CAD risk factors

7

Use in Life Insurance and LTC

8

Traditional CVD Risk AssessmentFramingham Risk Score – 10-year risk

Age and Sex Women get CAD at older ages; risk may be underestimated

Race

Total Cholesterol With extreme levels of a single risk factor, FRS may underestimate risk

HDL Cholesterol With extreme levels of a single risk factor, FRS may underestimate risk

Systolic BP

BP Meds (Y/N) But risk is actually graded, not just present or absent

Diabetes (Y/N) But risk is actually graded, not just present or absent

Smoker (Y/N) But risk is actually graded, not just present or absent

Other factors (Meh!)CRP

Hyperhomocysteinemia

Lipoprotein a

How to Use the CIMTin Insurance Underwriting

Underwriting Heuristic – create a rule that

modifies the current risk assessment

Replace chronological age with vascular age– Example 1: 45 yo man with low FRS (5% risk) and 50th percentile CIMT =

no adjustment

– Example 2: 45 yo man with low FRS (5% risk) but CIMT similar to 55 yo

man. Using 55 in the FRS calculation instead of 45 yields a 16% risk.

The Basics

Caused by the bacterium Borrelia burgdorferi

Transmitted to humans by infected ticks

Acute disease symptoms: rash (erythema migrans), fever,

headache, fatigue (days to weeks)

Early disseminated disease: cranial nerve palsies, radiculopathy,

peripheral neuropathy, lymphocytic meningitis (weeks to months)

Untreated disease late manifestations (months to years)

– Intermittent arthritis in a few large joints

– Subtle cognitive problems

Reported Cases of Lyme Disease - United States, 2013

Source: CDC

Diagnosis

Usually based on symptoms, characteristic rash, history of tick exposure

Blood tests (serologies) have problems– Negative is early stage of disease

– Often positive in endemic areas without evidence of active disease

– European forms of the disease require different tests

– Some labs use unreliable tests with high false-positive rate

18

Treatment

Most cases are treated successfully with

a two-week course of an antibiotic.

Those with late, untreated disease may

require intravenous antibiotics.

19

Outcomes

Close to 100% are cured with a 2-week course of an antibiotic

10–20% have lingering symptoms (PTLDS)– Fatigue, joint and muscle aches

– Persistent symptoms for 6 months or more

– Mechanism unknown

20

“Chronic Lyme Disease”

Lyme Group – Persisting symptoms after treatment for Lyme disease, called “post-treatment Lyme disease syndrome” (PTLDS)

CFS Group – Never had Lyme disease but have symptoms similar to PTLDS. In their search for the cause, found serologic evidence of Lyme disease.

21

CFS — Lyme Connection

Chronic fatigue syndrome (CFS) symptoms are common

Positive Lyme serology tests are common– Positive predictive value in patients with only nonspecific

symptoms is poor.– Some labs use non-validated tests

Leads to misdiagnosis based on a false-positive serologic test

22

Misattribution Leads to Inappropriate Treatment

Some doctors believe CFS symptoms are caused by persistent B. burgdorferi infection

Treat with prolonged courses of antibiotics

Patients who receive prolonged courses of antibiotics fare no better than those treated with placebo.

23

Treatment of PTLDS

Treat like fibromyalgia or CFS

Encourage patients to stay active

Rest, healthy diet

Cognitive behavioral therapy

24

Chronic Lyme Subculture

Similar to CFS, chronic candidiasis,

chronic EBV infection, etc.

Pseudoscience

Internet-based:– support groups– meetings– literature– activist groups

25

Bottom Line

10–20% of Lyme patients have post-treatment

symptoms that may last months

This does not mean persistent infection

No proof that chronic Lyme disease exists

Chronic antibiotic therapy is not needed
