The HDL Dilemma: What's Too High?

Are you worried about your HDL cholesterol level? You’re not alone! Many health-conscious individuals, like 62-year-old E.P., are trying to understand the implications of their cholesterol tests. E.P. recently discovered her HDL level was 87 mg/dL, which raised eyebrows due to conflicting research suggesting that levels above 80 mg/dL might be a concern.

The Good, the Bad, and the Confusing

Cholesterol can be confusing, especially when considering the different types of cholesterol in your body. Low HDL cholesterol is known to increase heart attack risks, while high levels are generally seen as protective. However, exceptions exist! Dr. Roach explains that in individuals with a family history of heart disease, high HDL cholesterol can sometimes be less beneficial. Unusually constructed HDL particles can be non-protective against inflammation, according to recent studies.

The Role of Family History

Family history plays a significant role in assessing heart health. Many common scoring systems for heart disease risk overlook this crucial factor. Interestingly, certain medications, like statins, can enhance the effectiveness of these ‘abnormal’ HDL particles. It’s essential to discuss personal and family health with your doctor to ensure a comprehensive evaluation!

Special Cases: Diabetes and Unique HDL Types

For individuals with diabetes, especially those on insulin, high HDL levels cannot be regarded as protective. In contrast, a rare form of HDL found in a small Italian village, known as ApoA-1 Milano, offers remarkable protection against heart disease, despite having low overall HDL levels.

Looking Towards the Future of Heart Health

The future of cholesterol assessment may shift from merely measuring levels to evaluating the function of cholesterol types and proteins. Tools like the PREVENT scoring system—especially when adjusted for family history—continue to be valuable for assessing heart disease risk.

Additional Testing: Is It Necessary?

If you have a robust family history of heart disease but normal cholesterol levels, consider additional tests like Lp(a), a lipoprotein that is a strong predictor of heart disease.

The Galleri Blood Test: A New Hope for Cancer Detection?

Shifting gears, let’s talk about the Galleri blood test for cancer detection, a topic that Anon raised. At 66 years old, many have experienced the anguish of late-stage cancer diagnosis. However, Dr. Roach remains cautious. While Galleri is an impressive advancement, its current sensitivity rates stand at only 30%! This means it might miss over two-thirds of pancreatic cancer cases.

Caution Advised: False Positives and Limitations

A negative result might give you a false sense of security, leading to missed early symptoms, while positive results might trigger anxiety and unnecessary invasive testing. With only 2.2% of positive tests confirming pancreatic cancer, it’s crucial to approach this test with a discerning eye. For now, Dr. Roach advises against routine use of the Galleri test but remains hopeful for improvements in early cancer detection technology.
