For years many people have relied on total cholesterol as the main indicator of heart health but cardiology experts say that number alone does not accurately reflect the real risk of heart disease. Cardiologist and heart transplant specialist Dr Dmitry Yaranov explains that cardiovascular damage is driven by specific cholesterol carrying particles rather than the total cholesterol value seen on routine blood tests.
According to Dr Yaranov understanding the structure and behavior of lipoproteins provides a far clearer picture of whether plaque is forming inside the arteries. In a recent social media discussion he highlighted six essential lipid markers that doctors use to assess heart disease risk more precisely.
Low density lipoprotein cholesterol known as LDL C plays a central role in plaque formation. When LDL levels rise cholesterol particles penetrate artery walls leading to inflammation and blockage over time. Reducing LDL is directly linked with lowering the chances of heart attack and stroke.
Another crucial marker is Apolipoprotein B or ApoB which reflects the total number of plaque forming particles in the blood. Since each harmful particle carries one ApoB molecule this marker offers a more accurate estimate of cardiovascular risk than LDL alone especially when values conflict.
Non HDL cholesterol captures all dangerous cholesterol particles including LDL and VLDL making it a useful alternative when ApoB testing is unavailable. Elevated non HDL levels are strongly associated with atherosclerosis.
Triglycerides are another important indicator. High triglyceride levels often suggest an excess of harmful lipoproteins and metabolic imbalance. When triglycerides are elevated experts recommend checking ApoB for deeper insight.
Lipoprotein a or Lp a is a genetically inherited cholesterol particle that significantly raises the risk of heart disease stroke and aortic valve disease. Many people are unaware they carry high levels which is why cardiologists advise testing it at least once in a lifetime.
Finally high density lipoprotein or HDL is commonly called good cholesterol because it helps transport cholesterol away from arteries. However Dr Yaranov stresses that high HDL does not neutralize the harm caused by elevated LDL or ApoB and should not be relied on as protective on its own.
In summary modern heart disease prevention focuses on lowering ApoB reducing LDL levels and understanding genetic risk factors such as Lp a to manage long term cardiovascular health more effectively.
