"Millions more people should be put on cholesterol-lowering statin drugs," BBC News reports. Draft guidance from the National Institute for Health and Care Excellence (NICE) has recommended that the drugs should be given to people with an estimated 1 in 10 or more risk of cardiovascular disease (CVD), which includes conditions such as heart disease and stroke.
Statins are medicines that can help lower rates of low-density lipoprotein (LDL) cholesterol (so-called "bad" cholesterol) in the blood. High rates of LDL cholesterol can lead to hardening of the arteries, a risk factor for CVDs.
At present, guidance for doctors on using statins to prevent CVD says that only people with a 20% or greater risk of developing CVD in the next 10 years should be offered the drugs.
The new guidance recommends lowering the risk threshold so statins are offered to people with a 10% chance of developing CVD. The draft guidance also recommends which assessment tool GPs should use to determine this risk.
NICE recommends that a specific statin called atorvastatin is used for both the prevention and treatment of CVD.
Statins are medicines that lower the rates of low-density lipoprotein (LDL) cholesterol in the blood.
Increased levels of LDL cholesterol are potentially dangerous, as this can lead to hardening of the arteries, a risk factor for heart attacks and stroke.
Statin treatment is usually recommended for certain groups:
The main new recommendations on the use of statins to prevent cardiovascular disease are summarised below:
The updated draft guidelines have been published by NICE, the National Institute for Health and Care Excellence. They are a draft update of the guidelines on lowering cholesterol (or lipid modification) that were published in 2008.
These are draft guidelines that have been published for consultation with professional and government organisations, patient and carer groups, and companies. These stakeholders have until March 26 2014 to comment before NICE decides on its final recommendations.
Anyone who wishes to comment on the guidelines must first register as a stakeholder. To find out more, visit the NICE consultation page.
The recommended changes have been made on the basis of cost effectiveness. For example, NICE concluded that high-intensity treatment with 20mg atorvastatin is more cost effective than statin treatment using medium-intensity simvastatin.
It also reports that medium-intensity treatment is more cost effective compared with no treatment or low-intensity treatment at all realistic risk levels.
The guideline group decided to change the threshold from 20% risk to 10% risk by taking into account "the uncertainty regarding the frequency of adverse events in routine clinical practice, which may be higher than in clinical trials, the uncertainty around the magnitude of the effectiveness of statins and the accuracy of the QRISK2 tool itself, as well as the base case cost effectiveness results and sensitivity analyses".
The drugs have become cheaper in recent years, and their effectiveness is well proven, NICE notes.
The organisation has also pointed out that although death rates from CVD have halved since the 1970s and 1980s, CVD is the cause of one in three deaths in the UK. At present, as many as seven million people in the UK are believed to be on statins, at an estimated annual cost of £285 million.
Headlines in some papers, such as the Daily Mail and the Daily Express, presented the draft guidelines as if they were the final recommendations, which is misleading.
It is also unclear how The Times concluded that most men over 50 and women over 60 are likely to be offered the drugs. At present, it is not known how many people will be offered statins under the new guidelines, but NICE estimates the number could be in the thousands.
Some of the reporting on the guidelines could also be misconstrued as saying that the use of statins would be compulsory, such as the Express' claim that, "Millions more to be given statins to ward off risk of stroke". As with all NHS treatments, statins would only ever been used if a person consents to treatment.
However, most of the reporting of the story was accurate, with some papers including useful comments from experts.
Statins can have side effects, although the most common ones, while a nuisance, are not serious. They include stomach upset, headache and insomnia. Occasionally, the drugs can cause inflammation and damage to the muscles. Serious side effects, such as jaundice and visual disturbance, are rare.
Statins are not suitable for everyone. For example, they should not be taken if you have severe liver disease or blood tests suggest your liver may not be working properly.

Professor Mark Baker, director of the Centre for Clinical Practice at NICE, said: "People with raised cholesterol levels and high blood pressure should reduce the amount of foods containing saturated fat they eat.
"They should exercise more and control their blood glucose levels by reducing their intake of sugar and by losing weight. They should also stop smoking."
