What's Happening?
Dr. Priyanka Sehrawat, an AIIMS-trained doctor, has brought attention to two lesser-known markers that can predict heart attack risk, beyond the commonly discussed LDL cholesterol levels. These markers are Apolipoprotein B (Apo B) and Serum Lipoprotein
(a) levels. Apo B is a protein found on the surface of atherogenic particles, and high levels indicate a higher number of harmful particles in the blood, which can penetrate artery walls. Serum Lipoprotein (a), or Lp(a), is similar to LDL but has an additional protein that makes it particularly harmful. High levels of these markers are associated with increased cardiovascular risk, even when LDL cholesterol levels are normal. These tests are not part of routine lipid profiles and need to be specifically requested.
Why It's Important?
The identification of Apo B and Lp(a) as significant markers for heart attack risk highlights the need for a broader approach to cardiovascular health assessment. This development could lead to more comprehensive screening processes, potentially improving early detection and prevention strategies for heart disease. Individuals with a family history of heart attacks may benefit from these tests, allowing for more personalized and effective management of their cardiovascular health. The emphasis on these markers could also influence public health policies and guidelines, encouraging healthcare providers to incorporate these tests into regular check-ups for at-risk populations.
