Compared with placebo, consistent MK-7 use was associated with 29% lower CAC progression and 42% less arterial calcium mass progression, though CAC still increased in both groups; stenosis increases were numerically lower with MK-7 but not statistically significant. Leyla notes many participants were on statins and were smokers, highlighting that statins can raise CAC by stabilizing soft plaque via calcification. The trial suggests MK-7 may slow calcification in newer plaques, may improve arterial elasticity via matrix GLA protein activation, is inexpensive and safe, but clinical event reduction remains unproven; Leyla suggests considering MK-7 (possibly 360 mcg) with vitamin D, magnesium, and dietary measures.","thumbnail_url":"https://img.transistorcdn.com/VqZUkCahxIiAeF5-K8EvRI1GWNHpDBp8Xmmm6hLF4BU/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9lODBh/MjZiYjExYzcxZDZh/MmFmZTQ5ZTgzYTI3/Mzk1OS5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
