left ventricular hypertrophy (LVH)

Etiology
- generally results from chronic hypertension
- LVH despite normal blood pressure suggests masked hypertension
Pathology
- associated with LV diastolic dysfunction
- associated with 5-14% risk of LV systolic dysfunction[2]
Genetics
- polymorphism in ANF receptor type A gene associated with left ventricular hypertrophy & decreased serum atrial natriuretic factor[4]
Diagnostic procedures
- electrocardiographic (ECG) criteria:
- tall left precordial R waves, deep right precordial S waves
- Sokolow-Lyon criteria
- Cornell criteria
- Casales criteria
- Romhilt-Estes scoring system
- R or S in any limb lead > 20 mm, or S in lead V1 or V2 > 30 mm, or R in lead V5 or V6 > 30 mm: (3 pts)
- left ventricular strain, ST segment & T wave in opposite direction to QRS
- ST segment depression bowed upward & T wave inversion
- no digitalis: (3 pts)
- + digitalis: (1 pt)
- left atrial enlargement: (3 pts)
- left axis deviation < -30 degrees: (2 pts)
- QRS duration > 90 ms: (1 pt)
- intrinsicoid deflection in lead V5 or V6 > 50 ms: (1 pt)
- total: 13 pts
- > 4 points = LVH
- left ventricular hypertrophy identified by ECG does not warrant an echocardiogram[9]
*Caution: LVH cannot be assessed in the presence of left bundle branch block (LBBB)
Management
- left ventricular hypertrophy with normal blood pressure suggests masked hypertension & warrants ambulatory blood pressure monitoring[5][6]
