Initial Work-Up for Mild Left Ventricular Hypertrophy

Diagnostic Evaluation

The European Society of Cardiology recommends beginning with comprehensive echocardiographic assessment and blood pressure evaluation, followed by targeted investigation for secondary causes and initiation of RAAS blockade if hypertension is present 1
Obtain transthoracic 2D echocardiography with Doppler to measure maximum diastolic wall thickness in all LV segments from base to apex using short-axis views, as recommended by the European Heart Journal 2, 3
Evaluate for left ventricular outflow tract obstruction with resting gradients and provocative maneuvers to exclude hypertrophic cardiomyopathy, according to the European Heart Journal 2, 4
Perform comprehensive diastolic function assessment including pulsed Doppler of mitral valve inflow, tissue Doppler velocities at mitral annulus, pulmonary vein flow velocities, pulmonary artery systolic pressure, and left atrial size/volume, as suggested by the European Heart Journal 2, 3

Measure blood pressure in both arms with patient supine and standing to assess for hypertension and orthostatic changes, as recommended by the American Heart Association in Circulation 5
Obtain 12-lead electrocardiogram to assess for voltage criteria of LVH, conduction abnormalities, and arrhythmias, according to the European Heart Journal and Circulation 1, 5
Screen for sleep apnea and sleep-disordered breathing, which are more common in hypertensive patients with LVH, as suggested by the European Heart Journal 1

Order complete blood count, serum electrolytes, blood urea nitrogen, serum creatinine, fasting glucose, lipid profile, liver function tests, and thyroid-stimulating hormone, as recommended by Circulation 5
Consider screening for specific etiologies if echocardiographic features suggest infiltrative disease, according to the European Heart Journal 2, 3, 6

Initiate ACE inhibitors or angiotensin II receptor blockers as first-line therapy in patients with LVH, as recommended by the European Heart Journal 1
Target blood pressure control aggressively, as effective antihypertensive therapy reverses LVH and decreases subsequent cardiovascular morbidity and mortality, according to Circulation 8
Prescribe sodium restriction and weight loss, which independently facilitate regression of LVH, as suggested by Circulation 8

Assess resting heart rate, as values >80-85 bpm portend adverse prognosis in hypertensive patients, according to the European Heart Journal 1
Evaluate for conduction delays at atrial and ventricular levels, particularly LBBB, which identifies patients at increased cardiovascular risk, as recommended by the European Heart Journal 1

Do not use non-dihydropyridine calcium channel blockers or digoxin if any degree of LV outflow tract obstruction is present, as these can worsen hemodynamics, according to the European Heart Journal 10, 11

Schedule serial echocardiography every 1-2 years to monitor for changes in LV mass, wall thickness, systolic and diastolic function, and development of complications, as recommended by the European Heart Journal and Praxis Medical Insights 4
