Can ldl be too low for a patient with a history of atherosclerosis, tia, hypertension and currently on noac? current ldl at 50 under 20mg simvastatin

LDL-P or LDL-C? Big: difference. Outcomes always match LDL-P (http://goo.gl/zwrkCs); Not LDL-C [a guess of how much cholesterol (in mg) is carried by all LDL particles in a dL of blood plasma] data, See: http://goo.gl/NmdIfm. Since every cell in body manufactures cholesterol (part of every cell membrane), very low LDL-C (down into teens) is rarely a health issue. LDL-P not being very low IS a major health issue.
