This study was a double-blind, randomised, multicentre clinical trial to study the effects of simvastatin in patients the first 90 days after a cortical stroke. The study included 60 patients with cortical strokes (a cortical stroke occurs when the blood supply to the outside, or cortex, of the brain is reduced or blocked, which results in brain damage) who were given either simvastatin or placebo at three to12 hours from symptom onset.

The study found:
(a) More patients taking simvastatin died compared to patients taking placebo.
(b) Patients taking simvastatin had a 140% increased risk of infection compared to patients taking placebo.

This study set out to investigate the effect of statin therapy on patients undergoing cardiac surgery with cardiopulmonary bypass. (Cardiopulmonary bypass is a technique that temporarily takes over the function of the heart and lungs during surgery, maintaining the circulation of blood and the oxygen content of the body). The study included 478 patients who stayed in hospital for an average of 25 days. They were divided into (i) statin taking group (ii) non statin group.

The study found:
(a) Patients taking statins had a 42% increased risk of death whilst in hospital compared to patients not taking statins.
(b) The statin taking group had a significant 16% lower Systemic Vascular Resistance Index compared to the non statin group. (A decrease of Systemic Vascular Resistance Index is evidence for systemic inflammation).

Review reveals statins only extend life by 3 or 4 days. Closer analysis finds they may actually shorten life.

This study was published in the BMJ Open 2015 Sep 24;5(9):e007118

Study title and authors:
The effect of statins on average survival in randomised trials, an analysis of end point postponement.

The objective of the study was to estimate the average postponement of death by statin users in statin trials. The study included an analysis of 11 trials that were defined by being randomised, having at least 1000 patients included, comparing a statin with no treatment or placebo, having at least two years of follow-up. Six of the studies were for primary prevention and five for secondary prevention with a follow-up between 2.0 and 6.1 years.

The analysis found:
(a) In primary prevention trials statin users lived an extra 3.2 days.
(b) in secondary prevention trials statin users lived an extra 4.1 days.

So the results show that - with the massive expense of buying the drugs, with the plethora of debilitating side effects, such as diabetes, muscle damage, heart failure, suicide, homicide, accidental death, cognitive impairment, Alzheimer's, dementia, birth defects, cancer, cataract, erectile dysfunction, fatigue, liver damage, lung disease, memory loss, pancreatitis, peripheral neuropathy, rhabdomyolysis, and many, many more - with all these toxic side effects statins may (supposedly) increase your life by only three of four days.

However, do they even prolong life by this paltry amount?

Clinical trials with statins are performed in highly selected populations. Most statin trials have exclusion criteria that screens out a significant percentage of people because of health and toxicity concerns. This has the effect of making the statin drugs look better than they actually are.

In the real world, few people are discouraged from using statins by the medical profession, so many people who would not be allowed in the clinical trials are taking statin drugs. This is why clinical trials show that side effects are suffered by about 5% of participants, yet in reality the figure can be anything from a fifth to over two thirds (or even more) of all statin users. 

The begs the question, that if more people suffer toxic side effects than the clinical trials portray, then do people who are taking statin drugs also have a shorter life?

In trying to determine an answer to this question it may be helpful to look at the exclusion criteria in the eleven trials in this study.

The eleven trials were:
ALLHAT
ASCOT
CARDS
JUPITER

WOSCOPS
4S

(xiii) Liver disease.
(xiv) Chronic muscle disease.
(xv) Prior cyclosporine.
(xvi) Life-limiting condition (cancer etc).
(xvii) Suspected poor compliance to protocol.

This investigation of the exclusion criteria and run-in phases of statin trials reveals the reasons that the large significant percentage of people are excluded from entering the statin studies.
(a) Most trials weed out people who are intolerant of statins.
(b) Subjects with liver or kidney problems are normally excluded.
(c) Women of child bearing age are routinely not allowed.
(d) Patients are often barred who have had surgical procedures.
(e) Most studies don't allow patients with a wide range of heart conditions.
(f) People who use drugs or alcohol are not included in statin studies.
(g) Up to 80% of screened potential subjects are rejected from the trials.
(h) Patients with various concomitant illness are invariably excluded from the trials.
(i) Patients taking a wide range of pharmaceutical drugs are not allowed into the studies.
(j) Poor mental function patients are screened out.
(k) Many of the trials weed out potential subjects who they suspect will have poor compliance in taking the statin drugs.
 
A couple of the studies have a 'run-in' phase where potential subjects are weeded out through various criteria. These trials have amounted to about a 50 to 80% exclusion rate before the trial begins. Nearly all the trials have a whole plethora of exclusion criteria and although it is very difficult to quantify how many people have been excluded, it may be argued that the 50 to 80% exclusion rate may be broadly similar.
 
How can we answer the question "do people taking statins have a shorter life?" 
 
The above eleven statin trials included 92,135 subjects. If we take the lower exclusion rate of 50%, then potentially about another 46,000 statin intolerant or statin incompatible people could have been included in the trials.
 
This would dramatically reduce the already paltry "three or four days statins add to life".
 
How can an accurate revised death rate figure can be calculated? I don't know if it's possible. But with data from an extra 46,000 statin intolerant people to be crunched there would be an exponential rise in side effects with a concomitant rise in deaths.
 
So, even if the actual exclusion rate figure is less than the estimated 50% exclusion rate figure, I suspect that this closer analysis of clinical trials reveals that statins may actually shorten life in the real world.

Statins do not prevent cardiovascular and all-cause deaths

This paper was published in the Journal of Clinical Lipidology Volume 7, Issue 3 , Pages 222-224, May 2013

Point: Why statins have failed to reduce mortality in just about anybody

Department of Medicine, McGill University, Montreal, QC, Canada H3H 1V6
 
 
This paper reviewed the scientific evidence regarding statins and death rates.
 
(i) In JUPITER (Justification for the Use of Statins in Primary Prevention: An Intervention Trial Evaluating Rosuvastatin trial), a trial involving 17,802 participants randomised to rosuvastatin or placebo found for all participants the cardiovascular mortality was not reduced.
(ii) All published trials with placebo controls conclusively establish that statins do not reduce mortality in women.
(iii) There are no mortality figures suggesting a positive effect for people taking statins for more than five or six years.
(iv) In the PROSPER (PROspective Study of Pravastatin in the Elderly at Risk) study, in patients older than 70 years of age, there appeared to be arising increased rate of cancer, which may indicate that longer intervals of statin therapy may have other costs in the elderly.
(v) For both genders, the lack of all-cause mortality benefit is also illustrated by all published studies using atorvastatin vs. placebo, including the summary of 49 in-house studies including 14,236 individual patients.
(vi) The secondary prevention study SPARCL (Stroke Prevention by Aggressive Reduction in Cholesterol Levels) ended with five more deaths on highdose atorvastatin than on placebo.
(vii) To date, there are no placebo-controlled studies showing a mortality benefit when patients used lovastatin, fluvastatin, cerivastatin, or pitavastatin.
(viii) No mortality benefit from statins has ever been shown in patients older than 70 years of age.
(ix) No mortality benefit from statins has ever been shown in patients with heart failure.
(x) No mortality benefit from statins has ever been shown in patients with kidney failure.
(xi) Patients believing consciously or subliminally that ‘‘their cholesterol is under control’’ because they take a statin may postpone embarking on lifestyle changes, such as stopping smoking and abandoning eating habits that produce obesity and diabetes.
(xii) There is evidence that statins themselves promote diabetes, a life-long health risk.
 
Vos advises: "Because the lack of circulating statins is not the cause of atherosclerosis and their benefit on mortality is highly questionable, we should concentrate on lifestyle changes. Exercise, no smoking, and a healthy diet are well demonstrated in population studies to reduce the high mortality seen in so many economically developed countries".
 
He concludes that statins: "do not prevent cardiovascular and all-cause deaths".

This study investigated the effects of statins in participants with a low risk of heart disease. The two year study was a randomised, double-blind, placebo-controlled trial of 984 individuals, average age 57 years. The participants received either a daily 40-mg dose of rosuvastatin or placebo.

The study found:
(a) Cholesterol levels reduced by 33% in the statin users and remained the same in those on placebo.
(b) Low density lipoprotein (LDL) cholesterol levels reduced by 49% in the statin users and remained the same in those on placebo.
(c) Statin users had a 21% increased risk of death compared to placebo.
(d) Statin users had a 423% increased risk of a serious adverse cardiovascular event compared to placebo.
(e) Statin users had a 4% increased risk of any adverse event compared to placebo.
(f) Statin users had a 5% increased risk of developing cancer compared to placebo.
(g) Statin users had a 5% increased risk of muscle pain compared to placebo.
(h) Statin users had a 121% increased risk of elevated liver enzymes compared to placebo.
(i) Statin users had a 56% increased risk of developing arthritis compared to placebo.

This study aimed to examine the impact of statins and low-density lipoprotein (LDL) cholesterol levels on survival rates in elderly patients with moderate and severe heart failure. The study included 212 patients, average age 77 years, who were followed for 3.7 years. The patients were divided into three groups according to LDL cholesterol levels:
(i) Group one had LDL cholesterol levels less than 90 mg/dL (2.32 mmol/l).
(ii) Group two had LDL cholesterol levels between 90-115 mg/dL (2.32-3.00 mmol/l).
(iii) Group three had LDL cholesterol levels above 115 mg/dL (3.00 mmol/l).

The study found:
(a) The total cholesterol levels of group one patients was 31% lower than group three patients.
(b) Group one patients were over twice as likely to be on statins than group three patients.
(c) Only 34% of group one patients survived longer than 50 months whereas 58% of group three patients survived longer than 50 months.

Charach concluded: "Low LDL cholesterol levels are associated with a reduced survival in elderly patients with clinically controlled moderate and severe heart failure. Statins were independently and significantly associated with a higher risk of mortality".

This study can be accessed at: http://www.ncbi.nlm.nih.gov/pubmed/12479764

This study, which lasted for 6 years, was designed to determine whether pravastatin compared with patients usual medical care, reduces death rates in patients aged 55 or older who have high cholesterol and blood pressure and other heart disease risk factors. 10,355 participants were enrolled in the study and were assigned into 2 groups where they received either 40 mg of pravastatin a day or their usual medical care.

The researchers found at the end of the 6 year study:
(a) Heart disease death rates were virtually identical in both groups.
(b) Those who took statins had an 11% increased risk of death from cancer compared to those who did not take statins.
(c) Those who took statins had an 7% increased risk of suicide/homocide/accidental death compared to those who did not take statins.

The results of this study suggest that statin treatment increases the risk of death from cancer.

Effect of rosuvastatin in patients with chronic heart failure (the GISSI-HF trial): a randomised, double-blind, placebo-controlled trial.
Gissi-HF Investigators, Tavazzi L, Maggioni AP, Marchioli R, Barlera S, Franzosi MG, Latini R, Lucci D, Nicolosi GL, Porcu M, Tognoni G.


The study investigated the effects of rosuvastatin in patients with heart failure. The study included 4,574 patients aged 18 years or older with chronic heart failure were assigned to either rosuvastatin 10 mg daily (2,285) or placebo (2,289) and followed up for 3.9 years.

The study found:
(a) Statin users had a 4% decreased risk of death from cardiovascular reasons compared to placebo.
(b) Statin users had a 12% increased risk of sudden cardiac death compared to placebo.
(c) Statin users had a 23% increased risk of fatal and non fatal stroke compared to placebo.
(d) Statin users had a 2.5% increased risk of death compared to placebo.

Tavazzi said: "In conclusion, results from the GISSI-HF trial might help physicians in taking the following decisions. First, not prescribing statins to patients with heart failure of non-ischaemic cause. Second, stopping statins in patients with heart failure of ischaemic cause".

This study investigated the effects of statin (atorvastatin) treatment in diabetic patients receiving hemodialysis. The study included 1,255 subjects with type 2 diabetes who were receiving hemodialysis who were assigned to receive either 20 mg of atorvastatin per day or matching placebo.

The study found:
  • Those receiving atorvastatin had twice the risk of a fatal stroke.
  • Death rates were similar in both groups.

This study found that atorvastatin increased stroke risk and had no effect on total death rates.

Division of General Internal Medicine and Department of Epidemiology and Biostatistics, University of California, San Francisco.


The aim of this analysis of 13 studies (which included 19,707 women) was to determine if cholesterol lowering drugs such as statins have any effect on heart disease rates and death rates in women. The study investigated results for both women with cardiovascular disease and without cardiovascular disease.

The study found:
(a) For women with heart disease statins marginally lower heart disease rates, however death rates from all causes remained the same.
(b) For women without heart disease statins marginally raise heart disease death rates, however death rates from all cause again remained the same.

This analysis of 13 studies found that statins offer no health benefits for women.

JUPITER statin trial a biased sham

Cholesterol Lowering, Cardiovascular Diseases, and the Rosuvastatin-JUPITER Controversy
A Critical Reappraisal
Michel de Lorgeril, MD; Patricia Salen, BSc; John Abramson, MD; Sylvie Dodin, MD; Tomohito Hamazaki, PhD; Willy Kostucki, MD; Harumi Okuyama, PhD; Bruno Pavy, MD; Mikael Rabaeus, MD

Dr. de Lorgeril notes that the results of cholesterol-lowering drug trials show no evidence that statin drugs lower the disease rates or death rates of people with or without coronary heart disease with one exception, and that is the JUPITER (Justification for the Use of Statins in Primary Prevention) trial. JUPITER reports a substantial decrease in the risk of cardiovascular diseases among patients without coronary heart disease and with normal or low cholesterol levels. 


The results of the JUPITER study were met with a massive media fanfare proclaiming the benefits of statin drugs. This enthusiastic recommendation has no doubt persuaded many people with normal cholesterol levels to start long term statin treatment.


The JUPITER trial tested the effects of rosuvastatin in patients without heart disease and with normal or low cholesterol levels but relatively high levels of C-reactive protein, a marker of inflammation. The study spanned 1,315 sites in 26 countries and included 17,802 people who were assigned either 20 mg/d of rosuvastatin or placebo.


3 recent trials with rosuvastatin (with the acronyms CORONA, GISSI-HF and AURORA) had been conducted, and all had failed to provide evidence that rosuvastatin therapy reduces heart disease complications.


The JUPITER trial was prematurely terminated on the grounds that it had generated evidence that the statin treatment had definitely reduced heart disease rates.


However the evidence shows otherwise:
(a) If you include people who had fatal and nonfatal heart attack and stroke - the trial was stopped after only 240 incidents. 
(b) There was no difference in the incidence of serious adverse events (total hospitalizations, prolongations of hospitalizations, cancer, and permanent disability) between the 2 groups.
(c) There was hardly any difference in death rates when the trial was ended, and the trend was showing that the statin groups death rate was increasing compared to the placebo group.


An "unequivocal reduction in cardiovascular mortality" was announced in March 2008 as the main justification for the premature trial termination.


However the actual facts again beg to differ:
(d) Fatal heart attacks were 9 in the statin group and 6 in the placebo group.
(e) Stroke death was 3 in the statin group compared to 6 taking the placebo.
So there was 12 cardiovascular deaths in each group. Hardly an "unequivocal reduction in cardiovascular mortality" as the JUPITER study authors concluded.


So why was the trial stopped early?


As stated earlier JUPITER was hailed in the media as a ringing endorsement for us all to start statin therapy. This was achieved by the authors of the study only highlighting some results of the trial and completely ignoring other, less favourable data. It also raises the suspicion that if the trial had continued then the results would have shown statins in an even more unfavourable light.


Rosuvastatin (sold under the brand name Crestor) is marketed and distributed by AstraZeneca Pharmaceuticals.


The JUPITER trial involved multiple conflicts of interest: 
(f) It was conducted by Astra Zeneca  with their obvious commercial interests. 
(g) Nine of 14 authors of the JUPITER article have financial ties to the Astra Zeneca. 
(h) The principal investigator has a personal conflict of interest as a co-holder of the patent for the C-reactive protein test.
(i) Astra Zenecas own investigators controlled and managed the raw data which increases the chance of bias appearing in the data.


Dr. de Lorgeril concludes:
(i) The results of the JUPITER trial are clinically inconsistent and therefore should not influence medical practice or clinical guidelines. 
(ii) The results of the JUPITER trial show that commercially sponsored clinical trials are at risk of poor quality and bias. 
(iii) The failure of the JUPITER trial to demonstrate a protective effect of rosuvastatin confirms the results of  more than 12 other cholesterol-lowering trials published in recent years, which all provided no evidence of protection against heart disease by cholesterol lowering. 
(iv) These failed trials strongly suggest that the presumed preventive effects of cholesterol-lowering drugs have been considerably exaggerated.


Dr.de Lorgeril ends by saying that the time has come for a critical reappraisal of cholesterol-lowering and statin treatments for the prevention of heart disease, and the emphasis on pharmaceuticals for the prevention of heart disease has diverted individual and public health attention away from other proven methods of prevention such as a healthy lifestyle, exercise and diet.

Statins offer no benefit to the elderly

This study was published in the Lancet 2002 Nov 23;360(9346):1623-30

Study title and authors:
Pravastatin in elderly individuals at risk of vascular disease (PROSPER): a randomised controlled trial.

The aim of the trial was to ascertain the effects of pravastatin treatment in elderly men and women aged 70-82. The study involved 2,804 men and 3,000 women (total 5804) with a history of, or risk factors for, vascular disease. They were assigned into groups of either a statin (pravastatin) or placebo and the study lasted for just over 3 years. Total deaths and adverse events of heart attack, stroke, cancer etc were measured.

The results of the study revealed:
(a) Total serious adverse events were the same in both groups.
(b) Heart disease was 19% higher in the placebo group.
(c) Stroke risk was 3% higher in the pravastatin group.
(c) Cancer risk was 25% higher in the pravastatin group.
(d) Total death rates were 6% higher in the pravastatin group.

The results show that 3 years of statin treatment did not add one day to the life of the participants of the trial.

Women should not be prescribed statins as they fail to provide any overall health benefit

This article was published in the British Medical Journal 2007 May 12; 334(7601): 983

Study title and author:
Malcolm Kendrick, general practitioner

Dr. Kendrick believes there is little or no evidence of health benefits for women taking statins.
 
He makes the following observations:
(a) To date, none of the large trials of secondary prevention with statins has shown a reduction in overall mortality in women.
(b) The primary prevention trials have shown neither an overall mortality benefit, nor even a reduction in cardiovascular end points in women.
(c) Women should not be prescribed statins. Not only do statins fail to provide any overall health benefit in women, they represent a massive financial drain on health services. This money could be diverted to treatments of proved value.
(d) Statins carry a substantial burden of side effects.
(e) Mass medicalisation is a dangerous road with many psychological and societal consequences.
(f) In the Scandinavian simvastatin survival study three more women died taking statins than the women who took the placebo.
(g) In the studies of primary prevention neither total mortality nor serious adverse events have been reduced.
(h) A meta-analysis published in the Lancet found that statins even failed to reduce coronary heart disease events in women.
(i) Another meta-analysis of statins in primary prevention suggested that overall mortality may actually be increased by 1% over 10 years (in both men and women).
(j) Data from 124,814 women in 19 studies and trials found that cholesterol levels had no impact on total death rates and heart disease.
(k) Studies have suggested that side effects from statins may be much more common than is recognised.
(l) One study found that 80% of athletes could not tolerate statins.
(m) Research by Golomb and McGraw found that doctors often dismiss most (probable) statin related events. Patients who met the criteria for definite or probable adverse events reported that their doctors tended to dismiss symptoms, deny specific statins adverse events, and failed to appreciate the effect of the adverse reaction on their quality of life.
(n) More evidence comes from the US Food and Drug Administration adverse event reporting system. Between November 1997 and May 2004 simvastatin was reported as a direct cause of 49,350 adverse events and 416 deaths.Adverse events are greatly under-reported, so the actual figures are likely to be much higher.
(o) Of further concern, as statins are increasingly prescribed to younger women, is the potential for birth defects, with severe neurological abnormalities reported. Spending millions on a treatment that has no proved benefit and may cause serious harm goes against the rationale of evidence based prescribing.
 
Women should not be prescribed statins as they fail to provide any overall health benefit.

Cardiologist questions the benefits of statins

This post includes a synopsis of a paper published in the Canadian Medical Association Journal November 8, 2005; 173 (10) and a recipe for huevos rancheros.

Study title and authors:
Questioning the benefits of statins
Statin Drugs Side Effects and the Misguided War on Cholesterol
Books:
Eddie Vos* and Colin P. Rose
*Sutton, Que.; Cardiologist, McGill University, Montréal, Que.

This paper can be accessed at: http://www.cmaj.ca/cgi/content/full/173/10/1207-a

Vos a cardiologist at McGill University, Montréal, notes that:
(a) Statins have failed to deliver in reducing all cause mortality
(b) There are no statin trials with even the slightest hint of a mortality benefit in women.
(c)  In patients over 70 years old evidence shows no mortality benefit of statin therapy.
(d)  In the ALLHAT study says it best: "trials [primarily in middle-aged men] demonstrating a reduction in [coronary artery disease] from cholesterol lowering have not demonstrated a net reduction in all-cause mortality." What is the point of decreasing the number of "events" without decreasing overall mortality, when the harm caused by the side effects of statin therapy is factored in?

Recipe of the day

Huevos Rancheros

Ingredients:
◦1 lb. link sausage
◦6 eggs
Esposito's Finest Quality Sausage - BREAKFAST SAUSAGE (8:1) - (4) 8 Link Packages (Net Wt. 4lbs.)
Food Mall: Sausage
◦1 green onion, chopped
◦1 avocado, chopped
◦Salsa

Method:
For the sausage, use a knife to split the link 3/4 of the way through and use your fingers to split it flat. Cook the sausages in a saute pan, that’s on medium high heat, with the casing side down. Why? Because the casing needs to render out otherwise the sausage will curl up, won’t crisp up and will taste oddly chewy.

While the sausage is browning, whisk together the eggs with a bit of salt. Remember, the salt helps keep the eggs tender. After the sausage is done, scramble the eggs in the sausage renderings, however you like–runny, slightly runny, hard and rubbery.

To serve, lay a few sausage links down on your plate, top with eggs, spoon with salsa and then sprinkle the green onions and avocado on top.

The elderly die earlier when taking statins

This paper can be accessed at: http://ageing.oxfordjournals.org/content/39/6/674.abstract
 
The author reviewed a total of 12 studies regarding the relationship of cholesterol levels and all-cause mortality. This corresponded to 13,622 participants: 3,789 aged 80 and above in eight studies and 9,833 aged 71103 (average age 78 years) in four studies.

The review found:
(a) Regarding all-cause mortality in the 80+-year olds, low cholesterol levels did not seem beneficial in any study and low cholesterol levels (less than 5.5 mmol/l or 212 mg/dL) is associated with increased mortality among 80+-year olds.
(b) There was no evidence that statins decrease all-cause mortality in elderly people without known vascular disease, on the contrary, it was even possible that statins increased all-cause mortality.

This finding of the review show that low cholesterol and possibly statin treatment increases the death rate in the elderly.
