If you are hoping to lower your risk of a heart attack simply by raising your levels of “good” cholesterol—high-density lipoproteins (HDLs)—you may be disappointed. Although epidemiological studies point to HDLs as protective against heart disease, a new genetic analysis presented at the meeting shows that while high HDL might correlate with a healthier heart, it’s not itself responsible for lowering heart attack risks.
