    Paradoxically the more Zetia (ezetimibe) lowered LDL, the greater the progression of atherosclerosis

    The greater the reduction in LDL cholesterol in statin users who were also given the cholesterol-lowering drug Zetia (ezetimibe), the greater the acceleration of atherosclerosis according to a study published in the New England Journal of Medicine.

    "We found an unexpected paradoxical relationship of a greater degree of atherosclerosis progression in patients with larger, [ Zetia-induced ] ezetimibe-induced reductions in LDL cholesterol level," the researchers noted.

    "The use of [ Zetia ] ezetimibe led to a paradoxical increase in the degree of atherosclerosis in association with greater reduction in LDL cholesterol, an effect we hypothesize may stem from unintended biologic effects of this agent," they concluded.

    But that's not all.

    Even though LDL levels were lower in the statin plus Zetia (ezetimibe) than the statin plus niacin group, during a 14 month period there were:
    Do not be fooled by some advertisement that says, "This drug lowers 'bad' LDL cholesterol." It is irrelevant! The ONLY thing that matters is if it lowers your TOTAL risk of death.

    Do not be fooled by whether or not a drug lowers some number on a piece of paper, that is, some marker, such as LDL cholesterol, blood pressure or blood sugar.

    The drug companies have convinced doctors and patients alike that if a drug lowers cholesterol... or blood pressure or blood sugar, that is must be good for you.

    This is not true!

    Studies going back to the early 1970's found that while oral diabetes drugs lower blood sugar, they caused more problems than they solved.

    A 2004 study of blood pressure drugs in older women found that while these drugs lowered blood pressure by 10-15 points lower than women taking no blood pressure drugs, women taking the drugs were MORE likely to die of cardiovascular disease in seven out of the eight ( 7 of 8 ) drug groups than the "no drug" group!

    Yes, really.

    In fact, women who had been given a diuretic plus a calcium channel blocker were 2.4 times MORE likely to die of cardiovascular disease than women taking no blood pressure medicines at all, even though the systolic pressure of the women taking this drug combination was 11 points lower (138 mm Hg in the drug group vs 149 mm Hg in the "no drug" group)!

    This is another example showing that the number on a piece of paper is irrelevant!

    It does not matter whether or not a drug lowers LDL cholesterol or blood pressure or blood sugar or any other marker.

    The only thing that matters is whether or not it lowers your total risk of death.

    Please do not fall for this advertising nonsense!

    Ignore LDL Cholesterol

    Dr. Rodney A. Hayward says we should IGNORE LDL cholesterol ignore

    Researchers quoted in the January 17th, 2008 cover story in BusinessWeek titled "Do Cholesterol Drugs Do Any Good", said that they research suggests that we should IGNORE LDL cholesterol altogether.

    "[C]urrent evidence supports ignoring LDL cholesterol altogether," University of Michigan's [Dr. Rodney A. Hayward, professor of internal medicine at the University of Michigan Medical School] was quoted as saying in this BusinessWeek article. Is LDL ‘Bad’ Cholesterol?

    Who says that LDL cholesterol is ‘bad’ cholesterol

    We have been told for 30 years or more that LDL cholesterol is “bad” cholesterol.

    This makes it sound like a waste product.

    It makes it sound like something you want to get rid of.

    It makes it sound like you should try to get it as low as possible.

    But we need to question this idea that LDL is “bad”.

    LDL cholesterol is not a waste product.

    It is there for a reason.

     

    Niacin Dose

    Niacin dose: 2000 mg of extended-release niacin at bedtime

    The dose of niacin was 2000 mg of extended-release niacin given at bedtime.

    Niacin was started at 500 mg for two weeks, then 1000 mg for two weeks, then 1500 mg for two weeks, then 2000 mg.

     

    Extended-release Niacin vs Regular Niacin

    A dose of extended-release niacin is roughly equal to twice the dose of regular niacin

    Here is a quote about regular niacin versus extended-release niacin from the 1993 book Coronary Heart Disease: The Dietary Sense and Nonsense. An evaluation by scientists in Chapter 8 titled “Clinical Alternatives” written by William B. Parsons, Jr, MD.

    “Playing niacin, in doses of [3000 mg] per day is usually quite safe, and the plain form seldom causes problems in doses up to [6000 mg] per day.

    “The relatively few reports of [liver] toxicity in recent years have usually occurred when a patient, physician, or pharmacist has not realized that substituting time-release niacin for plain niacin and equal dosage is the approximate equivalent of doubling the dose.

    “The fact that [liver] function alterations are more frequent with the time-release preparations has been recognized since the early 1960s.

    “The number of reported cases of [liver] toxicity has been relatively small, especially considering the greatly increased interest since publication of the [ National Cholesterol Education Program] guidelines in 1988.”

    —William B. Parsons, Jr, MD

     

    Patients Age

    Average age 65, all with cardiovascular disease

    All patients had cardiovascular disease or were considered high-risk.

    On average, patients were 65-years-old.

    Eighty percent (80%) were men.

     

    Patients Taking a Statin

    All patients had been taking a statin

    All were taking a statin, the average time having taking a statin was 6-years.

     

    95% on Zocor or Lipitor

    95% of patients were taking either Zocor (simvastatin) or Lipitor (atorvastatin)

    Ninety-five percent (95%) of patients were taking either Zocor (simvastatin) or Lipitor (atorvastatin).

    The average dose was 42 mg per day.

    Cholesterol and triglyceride levels at the start of the study were:

    The baseline level of total cholesterol was 146.1±23.6 mg per deciliter (3.8±0.7 mmol per liter); LDL cholesterol, 82.1±23.1 mg per deciliter (2.1±0.6 mmol per liter); HDL cholesterol, 42.4±8.5 mg per deciliter (1.1±0.2 mmol per liter); and triglycerides, 137±67 mg per deciliter (2±1 mmol per liter).

     

    Study Terminated Early

    Study terminated early because niacin was so superior to Zetia

    The study was terminated early, after 14 months, because niacin was so superior to Zetia (ezetimibe).

     

    Zetia Accelerated Atherosclerosis

    Zetia cause an acceleration of atherosclerosis even though it lowered LDL

    The also measured thickness of the carotid artery wall to try and determine if either of these agents caused regression of atherosclerosis.

    “Paradoxically, greater reductions in the LDL cholesterol level in association with ezetimibe [Zetia] were significantly associated with an increase in” thickness of the carotid artery wall.

    In other words, although Zetia (ezetimibe) reduced LDL cholesterol, it made the problem worse.

    It cause an acceleration of atherosclerosis.

    But that’s not all.

     

    Worsening of Atherosclerosis Greater

    The acceleration of atherosclerosis seen in the Zetia group was worse in those whose LDL was lowered the most

    The more Zetia (ezetimibe) lowered LDL cholesterol, the worse the problem got.

     

    This was NOT the case with Niacin

    This was NOT the case with niacin

    This was not the case with niacin.

    Here is the quote from the paper talking about this.

    “There was a significant inverse relationship between the changes in LDL cholesterol level and the carotid intima–media thickness in the ezetimibe group, such that a paradoxical increase in the carotid intima–media thickness was seen in patients [given Zetia] with greater reductions in LDL cholesterol. Such a relationship was not observed in the niacin group.”

     

    How A Drug Affects Your Risk of Death Is The ONLY Thing That Matters

    Do not be fooled by a drugs effects on markers such as LDL, blood pressure or blood sugar

    Do not be mislead by whether or not a drug lowers LDL cholesterol, or blood pressure, or blood sugar.

    Studies going back as far as the early-1970’s found that while oral diabetes medicines lower blood sugar levels, they cause more problems than they solve.

    Data from a 2004 study by Sylvia Wassertheil-Smoller, PhD from the Albert Einstein College of Medicine revealed that older women with “hypertension” who were given blood pressure drugs were more likely to die of cardiovascular disease in seven out of the eight drug groups compared to “hypertensive” women who were taking no blood pressure medicines at all even though systolic pressure in the drug groups was 10-15 points lower than in the non-drug group.

    Yes, really.

    So do not be fooled by how a drug affects a marker like LDL cholesterol, or blood pressure, or blood sugar.

    The only thing that matters is whether or not it lowers your total risk of death.
