High cholesterol isn’t just about one number: Cardiologist explains LDL, ApoB, Lp(a) and how to lower your real heart attack risk

For years, cholesterol has been painted as the enemy. A single number on a blood test often decides whether someone feels relieved or alarmed. But the truth is more layered.As Dr Sagar Shah, Consultant Cardiologist at Apollo Hospitals, Sheshadripuram, Bangalore, puts it, “For a long time, the message about cholesterol and lipids has been clear: it is bad. Whenever we see our blood reports, we are worried about cholesterol. But once you research more you find out that there is more to this than just a number, and it is quite interesting.”Cholesterol is not simply “good” or “bad.” It is essential for life. The real danger lies in how it travels in the body, how many particles circulate in the blood, and how long they stay there.
