Concentric LV Remodeling Treatment Approach
Definition and Characteristics
- Concentric LV remodeling is characterized by normal or small LV cavity size with increased wall thickness and normal left ventricular mass (LVM ≤115 g/m² in men or ≤95 g/m² in women), and relative wall thickness (RWT) ≥0.42, indicating disproportionate wall thickening relative to chamber size 2, 3, 4
- This pattern is associated with development of diastolic dysfunction with more dramatic degradation than other geometric patterns 5
Primary Treatment Strategy
- The American College of Cardiology recommends aggressive blood pressure control using angiotensin receptor blockers (ARBs), particularly losartan, as first-line therapy, with ACE inhibitors as an alternative 1
- Losartan demonstrates superior efficacy in reducing LV mass and myocardial fibrosis compared to beta-blockers, and is FDA-approved for hypertensive patients with LVH to reduce stroke risk 1
- ACE inhibitors serve as equally effective alternatives when ARBs are not tolerated, with comparable LV mass reduction 1
Combination Therapy Approach
- The European Society of Cardiology suggests considering aldosterone antagonists (eplerenone), which show efficacy equal to ACE inhibitors and may be more effective in combination, for patients who require combination therapy 1
- Calcium channel blockers (verapamil or diltiazem) can be added for patients with diastolic dysfunction 1
