Pricey Dr. Roach: I am a wholesome and pretty lively 62-year-old feminine. My blood stress and levels of cholesterol have at all times been superb, and there is no historical past of coronary heart points in my instant household. At my final checkup, my whole ldl cholesterol was 178 mg/dL; my LDL was 81 mg/dL; my triglycerides had been 61 (all a bit excessive for me); and my HDL was 87 mg/dL.
When reviewing these numbers, I seen that some analysis means that an HDL over 80mg/dL is simply too excessive and may presumably result in coronary heart or stroke points down the highway.
Are you able to touch upon what’s “too excessive” of an HDL?
— E.P.
Associated: Citrus bergomat dramatically lowers ldl cholesterol
Extra: Magnesium’s function in reducing coronary heart dangers
Pricey E.P.: Low ranges of HDL ldl cholesterol are recognized to be related to a better danger for coronary heart assaults, whereas excessive ranges of HDL are usually protecting. Nevertheless, there are a number of exceptions to this rule:
In some individuals with a powerful household of coronary heart illness and excessive HDL levels of cholesterol, the HDL particles had been discovered to be totally different from regular HDL particles and weren’t protecting in opposition to irritation in a cell tradition. Because of this, I take a look at household historical past as an important danger issue, which isn’t taken into consideration by a lot of the scoring methods that enable medical doctors to estimate coronary heart illness danger. (Curiously, using a statin drug helped the irregular HDL particles work extra successfully.)
Diabetics who’re on insulin usually have excessive HDL ranges, which can’t be thought of protecting. There’s additionally an uncommon sort of HDL particle present in an Italian village referred to as ApoA-1 Milano that’s extremely protecting in opposition to coronary heart illness, even with low HDL ranges.
I believe that sooner or later, we will likely be perform (as a substitute of simply ranges of ldl cholesterol varieties and associated proteins) to foretell coronary heart illness and decide who would profit from remedy. For proper now, a scoring system reminiscent of PREVENT (tinyurl.com/PREVENTCalc), modified by household historical past, stays the very best place for most individuals to begin.
Individuals with a powerful household historical past and regular or low levels of cholesterol ought to take into account extra testing, reminiscent of Lp(a), a lipoprotein that predicts coronary heart illness.
Pricey Dr. Roach: What’s your opinion on the brand new Galleri blood check that may assist detect cancers for which there are not any early screening? Like many individuals my age (66), I’ve recognized too many individuals who’ve died of pancreatic most cancers that was caught too late.
— Anon.
Pricey Anon.: Sadly, the check is not this beneficial but. It is an excellent check, however screening for a uncommon illness is proscribed by the truth that many individuals should be screened to seek out even one case. The check must be near-perfect for it to be helpful, and the present model of cell-free DNA testing is not fairly there.
The sensitivity of the check is about 30%, that means that it’s going to miss greater than two-thirds of individuals with pancreatic most cancers. Most individuals would assume {that a} adverse check means they do not have the illness, however this is not precisely true. It is potential that the false sense of safety may hold an individual from mentioning early signs to their physician.
The principle drawback is when the check result’s optimistic. An individual who receives the devastating information that their check is optimistic for pancreatic most cancers as a part of a screening is perhaps shocked to be taught that solely 2.2% of optimistic checks point out pancreas most cancers. Nonetheless, they’re prone to require extra, costly, anxiety-provoking and presumably invasive checks to conclude that the check was a false optimistic.
As a result of poor sensitivity and low optimistic predictive worth of the check, I’m not recommending it. However this expertise could finally be improved to beat these limitations. Readers could e mail inquiries to ToYourGoodHealth@med.cornell.edu.
