Screening for ventricular remodeling

Current guidelines emphasize the importance of preventing heart failure (HF) by targeting people with preclinical forms of the disease. Accordingly, there is considerable interest in identifying left ventricular (LV) remodeling, the fundamental substrate for HF, in asymptomatic individuals in the community. Increased LV mass and asymptomatic LV systolic and LV diastolic dysfunction are the remodeling phenotypes that could be potentially considered for population-wide screening. Plasma levels of natriuretic peptides (NP) have been extensively investigated for such screening purposes. However, a majority of investigations suggest that their performance characteristics are suboptimal for identifying LV remodeling phenotypes unless high-risk individuals (eg, older men with hypertension) are targeted. In general, the prevalence of LV systolic dysfunction in women is too low to justify screening. In recent reports, sequential screening strategies combining urine and plasma NP or plasma NP and hand-held portable echocardiography have been advocated as potential approaches to identify asymptomatic LV systolic dysfunction in a cost-effective manner. Additional studies are warranted to confirm these findings.
