A big climb-down for statin use

Statins for preventing heart disease were once so fashionable that some people were talking of adding it to the water supply. How the mighty are fallen!  The JAMA editorial below concludes that the benefit from taking statins is "marginal, likely small, and uncertain".  They also note that "the frequency of adverse effects increases as the statin dose increases".  Even for oldies it seems to give no benefit.  Statin prescribing has become routine among family doctors but they need to unlearn that


Statins for Primary Cardiovascular Disease Prevention Time to Curb Our Enthusiasm

In the US, more than 126 million adults have been diagnosed with cardiovascular disease (CVD).1 Reducing the morbidity and mortality associated with CVD is a public health imperative. Accordingly, considerable resources and effort have been invested in determining not only how to effectively treat symptomatic coronary artery disease or ischemic stroke, but also on prevention of clinical CVD. Although elevated low-density lipoprotein (LDL) is associated with higher rates of CVD,2 there is uncertainty regarding the net benefit to risk ratio of using statins to reduce LDL among persons without CVD (primary prevention). This contrasts with the established role of LDL reduction for persons with established CVD (secondary prevention).

The US Preventive Services Task Force (USPSTF) has updated its 2016 recommendations on the use of statins for the primary prevention of clinical CVD.3 Two of us (M.H.K. and R.F.R.) wrote about the 2016 recommendations,4 and in this Editorial we update our comments for the 2022 recommendations.5

The 2022 recommendations seem largely unchanged from the 2016 recommendations.3,5 For individuals aged 40 to 75 years without clinical CVD, with LDL lower than 190 mg/dL, and without known familial hypercholesterolemia, the USPSTF makes 3 recommendations. First, the Task Force concludes with moderate certainty that those with an estimated 10-year CVD event risk of 10% or higher based on the American College of Cardiology/American Heart Association pooled cohort equations (PCEs) and at least 1 risk factor—dyslipidemia (LDL of >130 mg/dL or high-density lipoprotein of <40 mg/dL), diabetes, hypertension, and/or smoking—are likely to derive moderate benefit (B recommendation) from initiation of a moderate-intensity statin (lowers LDL by 30%-49% on average). Second, the Task Force concludes with moderate certainty that those with an estimated 10-year CVD event risk of 7.5% to less than 10% and at least 1 risk factor are likely to experience small net benefit (C recommendation) from initiation of a moderate-intensity statin, and thus clinicians should engage patients in shared decision-making. Third, the Task Force concludes that there is insufficient evidence (I statement) to fully assess the net harms and benefits of initiating statins in adults 76 years and older, regardless of estimated 10-year CVD event risk or presence of risk factors.

The details of the updated recommendations merit further consideration.5 The systematic review6 that accompanies the 2022 USPSTF recommendations examined 22 randomized clinical trials (RCTs; n = 90 624 participants) that compared statin therapy vs placebo or no statin, with a mean follow-up duration of 3 years. The systematic review examined the clinical end points of all-cause mortality, CVD mortality, fatal/nonfatal myocardial infarction, and fatal/nonfatal stroke among those with a mean age of 52 to 66 years, except for 1 trial that only enrolled older individuals between 70 and 82 years of age (Table6,7).

The updated evidence synthesis6 found that statins yielded a slightly smaller, but still statistically significant, reduction in all-cause mortality (pooled relative risk, 0.92; 95% CI, 0.87-0.98), as well as for myocardial infarction and stroke (Table). The USPSTF recommendations should be considered in the context of a meta-analysis, published in 2010,8 which included only trials that enrolled patients receiving high-risk primary prevention; this study showed no benefit on all-cause mortality with statins. The benefit for CVD mortality was not statistically significant (pooled relative risk, 0.91; 95% CI, 0.81-1.02). Notably, there was no significant statistical heterogeneity (I2 = 0) across the 12 trials (n = 75 138) examined. The null result was robust in sensitivity analyses that excluded trials that stopped early, trials that included patients receiving secondary prevention, good-quality trials, trials with at least 3 years of follow-up, and trials with participants with a median baseline LDL lower than 160 mg/dL.6 The lack of benefit on CVD mortality found in the 2022 evidence review6 and the lack of benefit on all-cause mortality in the purely high-risk primary prevention meta-analysis8 call into question the reliability of the all-cause mortality benefit reported in the systematic review that accompanies the 2022 USPSTF recommendations. Because 19 of the 22 included trials were industry sponsored, potential bias in the randomization processes, as well as the potential for exaggeration of net benefits,9 are of greater concern than for trials whose sponsors were disinterested with regard to the outcomes.

In contrast with its 2016 recommendations,3 the USPSTF no longer recommends use of low-intensity statins in certain situations. This change is driven by the fact that 17 of the 22 trials had fixed-dose statin groups, including 12 which used moderate-intensity statins.6 We are unaware of any RCTs that directly compare either different statin intensities in terms of clinical CVD outcomes or fixed-dose vs titrate-to-LDL goal approaches. While it is understandable that the Task Force was limited by lack of data on dosing, this change is unfortunate for patients because the frequency of adverse effects increases as the statin dose increases.

Finally, the 2022 recommendations no longer note the “uncertainty in individual risk prediction” in contrast with the 2016 recommendations, which more clearly acknowledged that cardiac risk prediction is not an exact science.3,5 Refining the accuracy of prediction of risk for individuals remains a major issue for primary prevention. It is disappointing that there was no sex-specific analysis in the evidence review, as women have lower cardiovascular risk than men at all ages until age 75 years and are more likely to experience adverse drug effects than men.29 Thus, the risk-benefit profile for statins is less favorable for women than men, which is neither discussed nor recognized in the current USPSTF recommendations.

Many of the caveats and concerns noted in the Editorial accompanying the 2016 USPSTF recommendations4 are still present with the 2022 recommendations.5 These include the heterogeneous inclusion criteria across studies and the inclusion of participants not receiving primary prevention who either had symptoms consistent with clinical CVD10,11 or known coronary artery disease equivalents, such as carotid artery atherosclerosis.12 As noted previously, a meta-analysis of statins for patients receiving high-risk primary prevention found no benefit on all-cause mortality.8 Additionally, as the data for many trials of statin therapy remain unavailable, the USPSTF does not have access to participant-level data. The trials for which there is no data transparency are those with data housed at the Cholesterol Treatment Trialists’ (CTT) Collaborative at Oxford University.13 The CTT does not allow academic researchers and others access to the data from 24 trials comparing statins with a control group, starting in 1995. The CTT states that it is just the repository of data and cannot allow others access because the data are owned and controlled by the industry sponsors of the trials. In 2022, there is no reason for participant-level data from these trials to remain unavailable for independent analysis.

At present, there are further reasons to curb our enthusiasm about the use of statins for primary prevention of CVD. There is a difference between statistically significant and clinically meaningful benefit. The purported benefits of statins in terms of relative risk reduction are fairly constant across baseline lipid levels and cardiovascular risk score categories for primary prevention.6 Therefore, the absolute benefit for those in lower-risk categories is likely small given that their baseline absolute risk is low, while the chance of adverse effects is constant across risk categories.

Use of the PCE to risk-stratify individuals is problematic. The cut points of 5%, 7.5%, 10%, and 20% are arbitrary given the linear “continuum of risk”14 without a threshold effect3 that exists within the relationship between CVD risk and CVD occurrence. Additionally, the PCE itself is an imperfect tool to assess baseline 10-year absolute risk. The PCE was derived and validated in studies that enrolled individuals (mostly White males) between 1968 and 1990. Thus, the PCE does not reflect the recent decreases in rates of CVD that have accrued owing to population-wide health improvements from reduced rates of smoking, shifts in dietary patterns and exercise, and blood pressure control.15 In a multiethnic prospective cohort (n = 4227) from 2000 to 2002, the PCE overestimated CVD events by 86% in men and 67% in women.16 When applied to 6 cohorts from 1971 to 2014 (n = 26 689), the PCE overestimated 10-year risk of CVD by an average of 20% across risk groups, which would have down-staged 11.7 million adults from a 10-year CVD risk of greater than 10% to less than 10%, and 11.8 million adults from a 10-year CVD risk of greater than 7.5% to less than 7.5%.17 Furthermore, the PCE propagates the unavoidable variability and uncertainty in the clinical inputs (eg, total cholesterol, high-density lipoprotein, systolic blood pressure); a 10% higher or lower variation in these inputs would result in up to a 24% change in the risk categorization of individuals.18 Such issues with discrimination and calibration present challenges in applying the USPSTF guidelines to individuals in informing discussions about their potential for clinical benefits from statin use.

The USPSTF concluded that, among 19 RCTs and 3 observational studies examined (a different data set than the data set for the review of benefits, which was 22 RCTs),6 statins did not have any statistically significant harms, namely in terms of myalgias, incident diabetes, liver enzyme elevations, cancer, kidney effects, cognitive harms, or cataracts. However, in clinical practice, adverse events are commonly reported with use of statins. For example, in observational data, statin-associated muscle symptoms affect up to 1 in 10 individuals.19 Even if, as has been argued, statin-associated muscle symptoms are at least partly due to the nocebo effect,20 the extent to which muscle symptoms lead to either dose-reduction or discontinuation of statins (usually with subsequent cessation of these symptoms) should not be discounted. Although the USPSTF analysis6 did not find a statistically significant increase in incident diabetes, a prior meta-analysis of 13 trials (n = 91 140) found that 1 extra case of diabetes per 255 patients over 4 years of statin treatment could be attributed to statin use.21 Furthermore, individuals with other risk factors for glycemic intolerance and people with preexisting diabetes are likely to be at increased risk of progression to diabetes22 and worsened glycemic control, respectively.23 When assessing the potential harms of statins, it is prudent to keep in mind that although the purported benefits of statins will accrue to a few patients in the future, everyone prescribed a moderate-intensity statin is at risk immediately for the harms. Consideration of adverse effects is especially important for a primary prevention drug, which is prescribed to healthy people who feel perfectly well.

The practice of medicine is an art as well as a science. As the USPSTF and other professional societies, including the American College of Cardiology/American Heart Association24 and the European Society of Cardiology/European Atherosclerosis Society14 have all emphasized, shared decision-making of the anticipated benefits, harms, and uncertainties in predicting CVD are essential in determining whether to initiate a medication that a patient may possibly take for the remainder of their life. Although there are patient-facing decision-support aids for statins,25 they are underused. These aids would be more useful if quality-of-life data were collected in statin trials and could be added to decision-making tools. In addition, consideration should be given to deprescribing statins for adults 76 years or older, other older individuals unlikely to derive benefit from statins for primary prevention, and individuals who are at risk of polypharmacy because of medications taken for other conditions.

In the US, about $25 billion is spent annually on statins.26 Cardiovascular disease incidence and mortality are the upshot of myriad social determinants.27,28 Although statins lower LDL cholesterol in individuals, investments at the community level to construct a more salubrious environment that enables healthy eating and promotes physical activity are likely to have more widespread multiplicative and pleiotropic effects on the biological and psychosocial risks of CVD, as well as on improving quality of life. The 2022 USPSTF recommendations5 are an opportunity to pause and refocus efforts to meaningfully improve CVD outcomes for all, rather than extol the marginal, likely small, and uncertain absolute benefits of statins for the few in primary CVD prevention.

Shrieking lefties hate democracy — their attacks on the Supreme Court prove it

As the Supreme Court begins a new term that includes highly contentious cases on everything from voting rights to anti-Asian racism in elite college admissions, expect endless lefty and liberal attacks on the court’s very legitimacy simply because some decisions don’t go their way.  

A prime example: radical historian Jeff Shesol’s histrionic New York Times op-ed.

Shesol slams President Joe Biden for acting as a cowardly “bystander” in the face of the Supremes’ recent blockbuster decisions on abortion and gun control, as if it weren’t every president’s duty to respect the rulings of a judiciary that’s independent under the US Constitution even when he vehemently disagrees.

The Founders never intended the high court to be under the executive’s direct and sole political control. But Shesol instead urges Biden to imitate President Franklin Roosevelt’s full-on political and rhetorical assault on the court after it struck down some early New Deal laws (which were, in fact, breathtakingly unconstitutional: One of them aimed to give the prez the power to micromanage every business in country).

Notably, the public and a heavily Democratic Congress utterly rejected FDR’s move to pack the court. Yes, the Supremes later let other New Deal laws take effect — but only after the president backed off his unconstitutional vision.

Shesol calls the high court’s rulings on abortion and guns an “assault on democracy.” Yet the Dobbs ruling simply allows voters to decide on abortion restrictions. And while we criticized the Bruen decision on guns, it centered precisely on the protection of constitutional rights where the court is supposed to be “anti-democratic.”

Wealthy blue-staters having a tantrum does not a constitutional crisis make, but Shesol sure is rooting for one. No matter that, for decades, the court acted to write into the law precisely the policies that liberals love: abortion, quotas, gay marriage. (Though note that the “conservative” court last year upheld gay marriage: Sometimes, what the left favors doesn’t defy the Constitution.)

Saying the court is illegitimate simply because it strikes down actions that Congress clearly hadn’t authorized (as Shesol does over the Supremes’ nixing of far-reaching environmental rules) is insanely partisan and profoundly destabilizing of our democracy. That this view has taken root among Dem politicians is frightening.

An avalanche of this hysterical extremism is on the way, make no mistake. So best pray that Biden — who seems an increasing hostage to the activist wing of his party — has enough presence of mind left to not try following in FDR’s footsteps.

Why Hispanic voters are rejecting the wokesters — and its a huge problem for the Dems

One of the most significant events in American politics is that Hispanics are, in effect, deciding that they are working-class voters rather than ethnic-grievance voters.

This is so momentous because it means that Democrats can’t rely on the monolithic Hispanic voting bloc they imagined would guarantee them an enduring electoral majority, and that the shift to the Republicans may be just beginning (the migration of working-class whites to the GOP has been happening over the course of a couple of generations).

A NBC News/Telemundo poll of Hispanics has Democrats ahead of Republicans in the battle for Congress 54-33 percent. That’s a healthy lead, but it’s down from prior polls. Democrats led among Latinos by 42 points in October 2012, 38 points in October 2016, and 26 points in October 2020. Detect a trend?

Republicans don’t have to win Hispanics outright to change the calculus of American politics, only eat into Democratic margins.

In specific places, they’re doing even better. A Sienna College poll shows Gov. Ron DeSantis and Sen. Marco Rubio, both running for re-election in Florida, above 50% among Hispanics. A new poll for The Nevada Independent has Republican Adam Laxalt, challenging Democrat Catherine Cortez Masto, down by only 2 points among Hispanics.

It wasn’t supposed to happen this way. Progressives had Hispanics pegged as “non-white” voters, which meant they’d be animated by the same worldview as black Americans and become nearly as immovably Democratic. The arbiters of such things even cooked up a new term for Hispanics, “Latinx,” to signal their assimilation into the hothouse world of woke politics, with its kaleidoscope of genders and other bizarre priorities.

Yet “Hispanic” is an incredibly wide-ranging category including people from different countries and regions who may have lived here for generations or just got here recently. Generalizations are inevitably simplifications, but it’s safe to say they don’t have much in common with American blacks, who went through the uniquely searing experience of enslavement and systematic discrimination.

Within memory, blacks had to fight for the basic legal protections of citizenship, whereas many Hispanics got here after 1980, when the most fundamental civil-rights struggles had already been won.

In a piece for Spectator World, the Republican pollster Patrick Ruffini argues that Hispanics are tracing the basic trajectory of white Catholics as they assimilate, move to the suburbs and hew to traditional values out of fashion with the nation’s elite.

Analyst Ruy Teixeira has noted the clashing cultural attitudes of “strong progressives” and Hispanics. According to Echelon Insights survey, 66% of progressives reject the idea that America is the greatest country in the world; 70% of Hispanics disagree. Asked whether racism is built into our society or comes from individuals, 94% of progressives say it is systemic, and 58% of Hispanics say it is from individuals.

The same divides are evident on transgender sports, defunding the police and the importance of hard work.

The picture is of a constituency that is going to be skeptical of a party that made excuses for the 2020 riots premised on the notion that America is fundamentally corrupt, or that is on board the rush to embrace a non-binary future. Needless to say, this is not FDR’s Democratic Party, which had such a hold on white Catholics for so long.

On the cultural questions in the Echelon survey, Hispanics are much closer to working-class voters than the wokesters. This shouldn’t be a surprise since about 80% of Hispanics aged 25 or above don’t have a four-year degree, whereas hyper-progressives are disproportionately college-educated. Like other working-class voters, Hispanics are focused on the economy, and give President Joe Biden failing grades.

None of this means the Hispanic trend toward Republicans is inexorable. Rather, it shows that, despite Democratic hopes, these voters are up for grabs, and their support has to be earned like that of other Americans.

Australia: Sikh's bid for weapons act amendment rejected in Supreme Court

Sikhs are often in trouble over this.  But it is part of their faith.  Religious accomodations are extended to Muslims and Aborigines.  Why not Sikhs?

The state government has dismissed a Supreme Court application which would allow knives to be carried into Queensland schools for “genuine religious purposes”.

Court documents have revealed the director of an Australian religious group had applied for the state’s weapons act be amended in the Queensland Supreme Court.

The application was made by Kamaljit Athwal, the director of the Sikh Nishkam Society of Australia, who said the weapons act prevented her and others from entering Queensland schools for educational purposes.

According to the court document, Ms Athwal is an initiated as an Amritdhari Sikh and has been the society’s director since 2010.

Initiated Sikhs are required at all times to wear or possess five mandatory “articles of faith” which include an undergarment, a small wooden comb, an iron band, have “un-cut” hair covered by a turban and a ceremonial sword.

The sword, known as a Kirpan, is made of steel or iron and is usually worn underneath clothing on a sling.

Ms Athwal argued in the court document that if a Sikh were to remove any of the articles of faith they must go refrain from eating or drinking for a period of time.

“That would extend to the removal of the Kirpan to enter school grounds,” the document read.

Ms Athwal said she and other initiated Sikhs had been excluded from school drop-offs and pick-ups, from attending assemblies, meeting teachers, attending school activities and conducting work on school groups.

Further, Ms Athwal contended her ability to vote at government elections at her local school had been deprived.

Under the weapons act, a person must not physically possess a knife in a public place or a school unless the person has a reasonable excuse.

Maximum penalties including one year’s imprisonment.

The state government acknowledged the difficulties initiated Sikhs faced however, on September 30 it dismissed the court application
