Millions of Americans’ cholesterol risk just skyrocketed overnight. But are statins the answer?<\/h1>\n\n\n\n

New cholesterol guidelines aim to tackle heart disease decades before it strikes<\/p>\n\n\n\n

When is your cholesterol high enough that you need medication? You might expect there to be a simple cut-off. Above this number, you need statins. Below it, you don\u2019t.<\/p>\n\n\n\n

But doctors don\u2019t just look at your cholesterol in isolation. It\u2019s fed into a formula \u2013 alongside variables like your age, blood pressure, medical history and lifestyle \u2013 that estimates your overall risk of having a heart attack or stroke in the years ahead. Rewrite the formula slightly and suddenly you could find yourself being offered statins.<\/p>\n\n\n\n

That\u2019s exactly the situation for millions across the US following a major overhaul of cholesterol guidelines<\/a> from the American Heart Association (AHA).<\/p>\n\n\n\n

Around 87.5 million people \u2013 more than half<\/em> of Americans aged 30\u201379 \u2013 now meet the criteria<\/a> for statin treatment, a jump of 21.5 million since the AHA\u2019s last guidance in 2018.<\/p>\n\n\n\n

One of the biggest changes is how early doctors start looking at your cholesterol risk. Cardiovascular risk assessment used to start relatively late in life \u2013 now it begins a decade earlier.<\/p>\n\n\n\n

\u201cPrior guidelines released in 2018 focused on patients ages 40 to 75,\u201d says Dr Stephen Kopecky<\/a>, cardiologist at Mayo Clinic.<\/p>\n\n\n\n

The new guidelines have broadened the age range for risk estimation to 30\u201379, allowing doctors to better monitor a person\u2019s long-term cardiovascular risk.<\/p>\n\n\n\n

\u201cWith this younger age group, the equation now used to estimate risk includes 30-year risk in addition to the 10-year risk we have commonly used in the past,\u201d Kopecky explains.<\/p>\n\n\n\n

In other words, doctors used to focus on one question: what are your chances of having a heart attack or stroke in the next 10 years?<\/p>\n\n\n\n

Now, for younger adults, they\u2019re also looking much further ahead, at the risk over the next 30 years.<\/p>\n\n\n\n

That can paint a very different picture of somebody\u2019s risk of cardiovascular disease. A 35-year-old might have little chance of a heart attack in the next decade, yet still be on a path that puts them at much greater risk by their 50s or 60s.<\/p>\n\n\n\n

Under the new guidelines, if that longer-term risk is high enough, they may be offered statins even when their short-term risk remains low.<\/p>\n\n\n\n

When it comes to preventing heart attacks and strokes, time is one of the most valuable tools doctors have. Seen that way, the new guidelines are a positive, proactive step \u2013 catching risk earlier, before damage sets in.<\/p>\n\n\n\n

But qualifying for a prescription and actually needing one aren\u2019t the same thing. And for the 21.5 million people newly caught by this wider net, working out the difference matters.<\/p>\n\n\n\n

Numbers game<\/h2>\n\n\n\n

There\u2019s little doubt, in general, that statins work. Depending on the type and dose, they can reduce low-density lipoprotein (LDL) \u2013 the \u2018bad\u2019 cholesterol that contributes to fatty plaques building up inside our arteries \u2013 by around 30 to 50 per cent<\/a>.<\/p>\n\n\n\n

The more difficult question is when<\/em> to start taking statins.<\/p>\n\n\n\n

Statins are traditionally prescribed later in somebody\u2019s life, but the damage caused by high LDL cholesterol can start decades earlier.<\/p>\n\n\n\n

Over time, LDL cholesterol can build up as fatty plaques inside your artery walls, meaning how long your arteries have been exposed to moderately high levels may matter as much as how high your cholesterol is today.<\/p>\n\n\n\n

This also means a cholesterol reading that looks relatively healthy today isn\u2019t a guarantee against problems later.<\/p>\n\n\n\n

Doctors typically consider LDL below 2.6mmol\/l (100mg\/dL) optimal, yet around half of all heart attacks occur in people with levels between 2.3mmol\/l (89mg\/dL) and 3.8mmol\/l (147 mg\/dL) \u2013 a range that starts within what\u2019s considered healthy.<\/p>\n\n\n\n

So why wait, experts are now asking, until someone\u2019s risk becomes high before stepping in? When we\u2019re younger, plaques tend to be less established and easier to modify. As they accumulate and become increasingly calcified with age, some of the damage becomes much harder to reverse.<\/p>\n\n\n\n

Lowering LDL sooner could therefore prevent some of that damage from developing in the first place.<\/p>\n\n\n\n

\u201cSome studies have shown that even a low dose [of statins] can be very beneficial when given over many years to reduce plaque formation,\u201d says Kopecky. \u201cThe potential benefit regarding 30-year risk is quite real.\u201d<\/p>\n\n\n\n

Intriguingly, lowering cholesterol with statins may have a greater proportional<\/em> effect when someone\u2019s immediate cardiovascular risk is still low.<\/p>\n\n\n\n

According to Prof Kausik Ray<\/a>, Honorary Consultant Cardiologist at Imperial College London, among people at very low risk, a 1mmol\/l(39 mg\/dL) reduction in LDL has been associated with around a 36 per cent cut in their chances of a major cardiovascular event.<\/p>\n\n\n\n

Among those whose cardiovascular risk is already much higher, the same reduction is associated with a smaller cut, of around 13 per cent.<\/p>\n\n\n\n

That doesn\u2019t mean healthy young people have more to gain from statins than someone at high risk of a heart attack or stroke.<\/p>\n\n\n\n

A 36 per cent reduction sounds enormous, but if your chances of having a heart attack are very small to begin with, the actual difference to your odds may still be small. Someone with a 1 per cent chance of a cardiac event a year, for instance, might see that fall to around 0.64 per cent.<\/p>\n\n\n\n

For someone at high risk, a smaller percentage reduction can still translate into a much bigger real-world drop: someone with a 10 per cent chance might see it fall to around 8.7 per cent \u2013 a smaller relative cut, but a bigger absolute one.<\/p>\n\n\n\n

This doesn\u2019t mean everyone should start taking statins in their 30s, either. A major question remains unanswered: if someone starts at 30 or 40 to head off a risk that may not become significant for decades, how long do they actually need to stay on the medication?<\/p>\n\n\n\n

For now, nobody knows. The long-term data simply doesn\u2019t exist yet. But Kopecky says it may eventually prove possible to use statins intermittently \u2013 with periods on and off the medication \u2013 but \u201cthese are questions that have not yet been answered\u201d.<\/p>\n\n\n\n
