Acute coronary syndrome is a term given to various heart conditions, including a heart attack and unstable angina. These conditions are due to there being a reduced amount of blood flowing to a part of the heart.

Percutaneous coronary intervention, or coronary angioplasty is a procedure to unblock a coronary artery.

The purpose of the study was to examine the association between statin use and the risk for diabetes in patients with acute coronary syndrome following percutaneous coronary intervention. The study include 9,043 statin users and 9,043 non-statin users.

The study found:
(a) Statin use was associated with a significant increase of 27% in the risk for new-onset diabetes compared to non-statin use.
(b) Almost all types of statins were associated with a statistically significant increase in the risk for new-onset diabetes compared to those without statin use.

Lin concluded: "Our study indicated an association between increased risk for new-onset diabetes mellitus and statin use."

The objective of the study was to examine the associations of short-term statin use (less than one year) with adverse events and cardiovascular outcomes in 'healthy' people. The study matched 1,525 statin users to 1,525 nonusers who were followed for six years.
(i) Statin users used statins for 90-365 days during 2005 as their only prescription medication.
(ii) Nonusers had medical encounters but did not receive prescription medications during 2005, and did not receive any statins throughout the study period.

The study found:
(a) Statin users had a 93% increased risk of developing diabetes compared to nonusers.
(b) Statin users had a 115% increased risk of developing diabetic complications compared to nonusers.
(c) Statin users had a 17% increased risk of suffering major acute cardiovascular events compared to nonusers.

Mansi concluded: "Short-term statin use for primary prevention in this healthy cohort was associated with an increased risk of long-term diabetes and diabetic complications without cardiovascular benefits."

This paper systematically reviewed the results of high-quality double blind trials testing whether cholesterol-lowering drugs (statins and fibrates) reduce mortality and cardiovascular complications specifically in type two diabetics.

The review of the scientific literature found four trials, three statin and one fibrate.
(a) Statin trials:
(ai) The Collaborative Atorvastatin Diabetes Study (CARDS) trial was discontinued 2 years before the anticipated end and in the absence of significant effect on both overall and cardiovascular mortality, suggesting that the trial should not have been prematurely stopped.
(aii) The Deutsche Diabetes Dialyse Studie (4D) trial showed no significant effect on heart attack, stoke or cardiovascular and overall death rates.
(aiii) The Atorvastatin Study for Prevention of Coronary Heart Disease Endpoints in Non-Insulin-Dependent Diabetes Mellitus (ASPEN) trial showed no significant effect in nonfatal heart attacks, nonfatal stroke, coronary artery bypass surgery, resuscitated cardiac arrest, worsening or unstable angina requiring hospitalization or cardiovascular and overall death rates.
(b) Fibrate trial: The Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) trial showed no significant effect on coronary heart disease death, non-fatal heart attack or death rates.

Dr de Lorgeril concluded: "This review does not support the use of cholesterol-lowering drugs (such as statin and fibrate) to reduce mortality and cardiovascular complications in type two diabetics. Official guidelines should be re-examined and reformulated by experts independent from the pharmaceutical industry".

The term HbA1c refers to glycated haemoglobin. It develops when haemoglobin, a protein within red blood cells that carries oxygen throughout your body, joins with glucose in the blood, becoming 'glycated'.

By measuring glycated haemoglobin (HbA1c), clinicians are able to get an overall picture of what our average blood sugar levels have been over a period of weeks/months.

For people with diabetes this is important as the higher the HbA1c, the greater the risk of developing diabetes-related complications.

This study examined the association between statin use and HbA1c levels in type 1 diabetics without known heart disease. The study included 1,093 patients, average age 49.6 years, who had had type 1 diabetes for an average of 25.5 years.

The study found that statin use was independently and significantly associated with higher HbA1c levels.

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".

The objective of the study was to examine the association between statin use and new-onset diabetes, diabetic complications, and overweight/obesity in healthy adults. The study lasted 8.5 years and included 3,351 statins users who were matched with 3,351 nonusers.

The study found:
(a) Statin users had a 87% increased risk of developing new-onset diabetes compared to nonusers.
(b) Statin users had a 150% increased risk of developing diabetes with complications compared to nonusers.
(c) Statin users were 14% more likely to be overweight or obese compared to nonusers.

Mansi concluded: "Diabetes, diabetic complications, and overweight/obesity were more commonly diagnosed among statin-users than similar nonusers in a healthy cohort of adults. This study demonstrates that short-term clinical trials might not fully describe the risk/benefit of long-term statin use".

The objective of the study was to investigate the relationship between adherence with statin therapy and the risk of developing diabetes. The seven year study included 115,709 patients who were newly treated with statins. Adherence was measured by the proportion of days covered with statins.

The study found: 
(a) Compared with patients with very-low adherence (proportion of days covered less then 25%) those with low adherence (proportion of days covered 26-50%) had a 12% increased risk of developing diabetes.
(b) Compared with patients with very-low adherence (proportion of days covered less then 25%) those with intermediate adherence (proportion of days covered 51-75%) had a 22% increased risk of developing diabetes.
(b) Compared with patients with very-low adherence (proportion of days covered less then 25%) those with high adherence (proportion of days covered more than 75%) had a 32% increased risk of developing diabetes.

Corrao concluded: "In a real-world setting, the risk of new-onset diabetes rises as adherence with statin therapy increases".

Possible mechanisms of how statins cause diabetes

Brault notes that new-onset diabetes has been observed in clinical trials and meta-analyses involving statin therapy. Brault discusses the mechanisms that may be involved between statins and diabetes.

(a) Statins affect insulin secretion through direct, indirect or combined effects on calcium channels in pancreatic β-cells.
(b) Statins reduce the expression of glucose transporter 4 (GLUT 4). GLUT 4 is a protein that transports glucose from the bloodstream into cells. Reduced GLUT 4 in response to statins results in hyperglycemia (high blood sugar) and hyperinsulinemia (excess levels of insulin in the blood).
(c) Statin therapy decreases other important molecules such as coenzyme Q10, farnesyl pyrophosphate, geranylgeranyl pyrophosphate, and dolichol; their depletion leads to reduced intracellular signaling.
(d) Statins interference with intracellular insulin signaling pathways via inhibition of necessary phosphorylation events (phosphorylation influences protein enzymes) and reduction of small GTPase action (GTPases are key proteins in many critical biological processes such as hormonal and sensory signals, and the protein building ribosomes). 
(e) Statins can decrease levels of peroxisome proliferator activated receptor gamma and CCAAT/enhancer-binding protein which regulate glucose levels.
(f) Statins may also diminish levels of leptin and adiponectin which also play a role in regulating glucose levels.

The objective of this study was to examine the association of various drugs in patients with impaired glucose tolerance with new onset diabetes. The study lasted five years and included 9,306 patients. (If you have impaired glucose tolerance, your blood glucose is raised beyond the normal range but it is not so high that you have diabetes. However, if you have impaired glucose tolerance you are at risk of developing diabetes).

 

Regarding statins, the study found that statin use was associated with a 32% increased risk of new onset diabetes.

The aim of this study was to evaluate the influence of statins on the development of dysglycemia in kidney transplant patients. (Dysglycemia is defined as diabetes and impaired fasting glucose). The study included 394 patients without previously known diabetes or impaired fasting glucose who had undertaken kidney transplantation. Patients were grouped into the two groups according if they used statins (245 statin users and 149 nonusers).

The study found:
(a) Statin users had a 208% increased risk of dysglycemia compared to non users.
(b) The time to development of dysglycemia after transplantation was shorter in the statin group (38.8 months) than in the control group (47.2 months).

Choe concluded: "Statin treatment is associated with an elevation in fasting plasma glucose and in the development of dysglycemia in renal allograft recipients (kidney transplant patients)".

This paper can be accessed at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=34065

This paper undertook a comprehensive review of the scientific literature for articles relating to cardiovascular primary prevention and statin side effects.

 

The review found:

(a) There is a categorical lack of clinical evidence to support the use of statin therapy in primary prevention.

(b) Not only is there a dearth of evidence for primary cardiovascular protection, there is ample evidence to show that statins actually augment cardiovascular risk in women, patients with Diabetes Mellitus and in the young.

(c) Statins are associated with triple the risk of coronary artery and aortic artery calcification.
(d) There is increased risk of diabetes mellitus, cataract formation, and erectile dysfunction in young statin users.
(e) There is a significant increase in the risk of cancer and neurodegenerative disorders in the elderly plus an enhanced risk of a myriad of infectious diseases.
(f) A review of the use of statins found evidence of selective reporting of outcomes and failure to report adverse events.

Sultan concluded: "These finding on statin major adverse effects had been under-reported and the way in which they withheld from the public, and even concealed, is a scientific farce".

This study investigated the association between statins and diabetes risk. The study was a randomized, single-blind, placebo-controlled parallel study that was conducted in 44 patients taking placebo and in 42, 44, 43, and 40 patients given daily atorvastatin 10, 20, 40, and 80 mg, respectively, during a two-month treatment period.

The study found:
(a) Atorvastatin at 10, 20, 40, and 80 mg daily significantly increased fasting insulin levels by 25%, 42%, 31%, and 45%, respectively.
(b) Atorvastatin at 10, 20, 40, and 80 mg daily significantly increased glycated hemoglobin levels (HbA1c levels) by 2%, 5%, 5%, and 5%, respectively.
(c) Atorvastatin at 10, 20, 40, and 80 mg daily decreased insulin sensitivity by 1%, 3%, 3%, and 4%, respectively.

Stain treatment increased fasting insulin levels, increased glycated hemoglobin levels and decreased insulin sensitivity which all indicate an increased risk of diabetes.
