“…The prevalence estimates of hyperhomocysteinemia (>14 mmol/L) vary between 5% and 30% in the general population (Selhub et al, 1993;Nygård et al, 1995). Some epidemiologic studies (Hoogeveen et al, 2000;Vollset et al, 2001;Blacher et al, 2002;Gonzalez et al, 2007;Cui et al, 2008;Dangour et al, 2008;Waśkiewicz et al, 2012;Wong et al, 2012) but not all (Stehouwer et al, 1998;Kark et al, 1999;de Bree et al, 2003;Swart et al, 2012) indicated that the elevated Hcy represents a risk factor for total death, CHD death, or cardiovascular mortality in the general population; additionally, this incremental increase in risk was pronounced in high risk subjects (Nygård et al, 1997;Zylberstein et al, 2004;Rossi et al, 2006;Naess et al, 2013). Furthermore, two conducted studies (Bostom et al, 1999;Colon Lopez et al, 2008) were difficult to compare because the Hcy cut-off values varied.…”
