A 27-year-old man is found to have a total serum cholesterol concentration of 190 mg/dl at a routine examination. He has no family history of hypertension or premature coronary artery disease. His grandmother was diagnosed with type 2 diabetes mellitus at the age of 65 years. Examination shows no abnormalities. In addition to general dietary advice and education concerning risk factors, which of the following is the most appropriate next step in management? 0 A) Repeat measurement of serum cholesterol concentration in 5 years 0 B) Recommend the American Heart Association Step 2 cholesterol-lowering diet 0 C) Glucose tolerance test 0 D) X-ray of the chest 0 E) ECG
Quick Answer:
The correct answer is A) Repeat measurement of serum cholesterol concentration in 5 years.
This 27-year-old man has a total cholesterol of 190 mg/dL, which is desirable (under 200 mg/dL per ATP/NCEP guidelines). He has no personal or significant family history of premature CAD, hypertension, or hyperlipidemia. His grandmother's type 2 DM at age 65 is not considered a major risk factor for him. With no abnormalities on exam and no risk factors beyond his age, the appropriate step is simply to recheck cholesterol in 5 years per standard screening guidelines.
Why the other options are wrong:
- B) AHA Step 2 diet - This is reserved for patients who have already failed the Step 1 diet, or those with significantly elevated LDL. Not indicated with a normal cholesterol.
- C) Glucose tolerance test - There is no indication for diabetes screening here. His grandmother's T2DM at 65 is very distant family history and not a trigger for GTT in an asymptomatic 27-year-old with no other risk factors (no obesity, no symptoms mentioned).
- D) Chest X-ray - No clinical indication whatsoever in this scenario.
- E) ECG - No symptoms of cardiac disease, no risk factors that would warrant an ECG screening at age 27.
The key teaching point: Per NCEP ATP III guidelines, a total cholesterol < 200 mg/dL is "desirable." For a young, low-risk individual with desirable cholesterol and no significant risk factors, the recommended interval for repeat screening is every 5 years. No pharmacological or intensive dietary intervention is needed.

Here is a thorough breakdown of when pharmacotherapy (primarily statins) is started in an otherwise healthy person (primary prevention - no established cardiovascular disease):
When to Start Pharmacotherapy for Cholesterol in a "Healthy" Person
The Core Decision Framework
Pharmacotherapy is NOT based on total cholesterol alone. It is based on two things working together:
- LDL-C level
- 10-year ASCVD (cardiovascular) risk
Category 1: LDL-C ≥ 190 mg/dL - Start Statin Immediately
Per ACC/AHA guidelines (from Textbook of Family Medicine, 9e):
Adults ≥21 years with primary LDL-C ≥190 mg/dL should be treated with statin therapy - 10-year risk estimation is NOT required.
- Use high-intensity statin (e.g., atorvastatin 40-80 mg or rosuvastatin 20-40 mg) unless contraindicated
- This cutoff captures familial hypercholesterolemia (FH) and severe primary hypercholesterolemia
- Goal: achieve at least 50% reduction in LDL-C
Category 2: Age 40-75, Diabetes, LDL 70-189 mg/dL
- Start moderate-intensity statin therapy regardless of 10-year risk
- High-intensity statin if 10-year ASCVD risk is ≥7.5%
Category 3: Age 40-75, No Diabetes, LDL 70-189 mg/dL
This is the most nuanced group. Per Harrison's Principles of Internal Medicine, 22nd Ed.:
"The 10-year ASCVD pooled cohort risk calculator is used. A 10-year risk >7.5% merits consideration of statin therapy regardless of plasma LDL-C level."
| 10-Year ASCVD Risk | Action |
|---|---|
| < 5% (low) | Lifestyle only; no statin needed |
| 5-7.5% (borderline) | Discuss risk-benefit; consider statin if risk enhancers present |
| ≥ 7.5% (intermediate) | Start moderate-to-high intensity statin |
| ≥ 10% (high) | Start high-intensity statin |
Category 4: Age < 40 (like your 27-year-old patient)
Per Harrison's 22e:
"For younger patients, the assessment of lifetime risk of CVD may help inform the decision to start a statin, as well as a careful assessment of family history of ASCVD."
- The 10-year pooled cohort calculator is less reliable for young adults
- Unless LDL ≥190 mg/dL or FH is diagnosed, lifestyle modification is tried first
- Lifetime risk calculators or family history may tip the decision
When to Use Additional Risk Markers (Borderline Cases)
If the decision is uncertain, these tests help:
- Coronary Artery Calcium (CAC) score - men >40, women >50
- Lp(a) - elevated = higher risk
- hs-CRP - elevated = higher risk
- ApoB - elevated = higher risk
A CAC score of 0 favors deferring statin therapy; a score >100 supports initiating it.
Summary Table
| LDL-C | Risk | Action |
|---|---|---|
| < 190 mg/dL + 10-yr risk < 5% | Low | Lifestyle only; re-check in 4-6 years |
| < 190 mg/dL + 10-yr risk 5-7.5% | Borderline | Lifestyle + discuss; use risk enhancers to decide |
| < 190 mg/dL + 10-yr risk ≥ 7.5% | Intermediate/High | Start statin |
| ≥ 190 mg/dL (any age ≥21) | Any | Start high-intensity statin immediately |
| Established ASCVD (not "healthy") | Very high | Always start statin |
Back to Your Previous Patient (190 mg/dL total cholesterol)
His total cholesterol is 190 mg/dL, but LDL-C is not even measured/reported. At age 27 with no risk factors, his 10-year risk is well below 7.5%. That is why the answer was simply repeat in 5 years - he does not meet any threshold for pharmacotherapy.

Jugular Venous Distention (JVD) - Normal Limits
The Measurement
JVP is measured at 45° patient position, using the right internal jugular vein (preferred over external jugular because it is in direct line with the right atrium).
Normal Values
| Reference Point | Normal Upper Limit |
|---|---|
| Above sternal angle (angle of Louis) | ≤ 3 cm |
| Above right atrium (sternal angle + 5 cm) | ≤ 8-9 cm H₂O |
The formula is:
CVP (cm H₂O) = height above sternal angle (cm) + 5 cm
The 5 cm is added because the sternal angle sits approximately 5 cm above the right atrium in most patients at 45°.
So: Normal right atrial pressure = 5-10 cm H₂O, with 8 cm H₂O often cited as the upper limit of normal. (Goldman-Cecil Medicine)
What is "Elevated" JVP?
Per Symptom to Diagnosis, 4th Ed.:
JVD is defined as > 3 cm of elevation above the sternal angle - this is highly specific for heart failure (can occur in RV or LV failure).
So in clinical practice:
- ≤ 3 cm above sternal angle = Normal JVP
- > 3 cm above sternal angle (i.e., total CVP > 8-9 cm H₂O) = Elevated JVP / JVD
The JVP Waveform (Normal Components)
The normal JVP has distinct waves (best seen in the internal jugular vein):
| Wave | Cause |
|---|---|
| a wave | Right atrial contraction |
| c wave | Tricuspid valve closure / carotid pulsation transmitted |
| x descent | Atrial relaxation + tricuspid valve descent |
| v wave | Venous filling while tricuspid is closed (isovolumetric RV contraction) |
| y descent | Tricuspid valve opens, ventricle fills |
Key Clinical Pearl
- JVP is not directly palpable (unlike carotid) - it is visible but not felt
- It has a double waveform (a and v waves)
- If pulsations are not visible in the neck - pressure may be either very high (veins fully distended, no pulsation visible) or very low
- Abdominojugular reflux test: Press right upper quadrant for 30 seconds - a rise of ≥1 cm in JVP = positive, indicating elevated right-sided filling pressures
