New Book (2016) 

“Fat and Cholesterol Don’t Cause Heart Attacks 

And Statins Are Not The Solution” 

Edited by Prof. Dr. Paul Rosch this book is a tribute to Dr. Uffe Ravsnkov, an extraordinary and tireless researcher, founder of “The International Network of Cholesterol Skeptics (THINCS)”. Among other bookstores you can find this book at…/…/

Uffe Ravsnkov’s monograph, “The Cholesterol Myths”, can be read free of charge, at 

The present book contains 17 chapters written by a select group of medical researchers and scientists. 

I’m honored to participate in this tribute to Uffe Ravsnkov.

My chapter is entitled “Stress as Cause of Atherosclerosis – The Acidity Theory”.

During the last year I have presented an article about the acidity theory of atherosclerosis, developed in 2006, addressing its history, pathophysiology, therapeutics, risk factors and external markers. There I also have wrote about individuals with lower degree or absence of atherosclerosis, and on the reversion or lower progression of atherosclerosis through the use of sympatholytic drugs and by stress reduction approaches ( 

In this book (Chapter 10) I extend the discussion about the etiology of the Acidity Theory of Atherosclerosis, aside to present new risk factors and other diseases associated to atherosclerosis, under its point of view. Also, I brought up for discussion the inverse association between cancer and atherosclerosis, confirmed by recent studies*. Follows the abstract:

The link between stress and atherosclerosis is well-known with many studies and postulations in this regard. However, there is a general unawareness that stress can induce hyperlactatemia and lactic acidosis, because this relationship has been little discussed in medical science. The influence of adrenaline on lactic acid production was first noticed by Carl Ferdinand Cory in 1925. The heart is an organ of high metabolic activity – that cannot rest as other body muscles, being susceptible to drops in pH during ischemia and hypoxia. The chronic elevated catecholamine release, triggered by sympathetic dominance, may accelerate the myocardial glycolysis leading to significant increase in lactate production. Risk factors for atherosclerosis like hypertension, diabetes, cigarette smoking, stress conditions and high carbohydrate diets are linked to autonomic dysfunction. These risk factors present as well an increased concentration of lactate in plasma. Blood lactate is also associated with carotid atherosclerosis. Plasma lipid abnormalities and myocardial lactate production were significantly associated with subsequent arteriographic progression. The amount of lactate released by the myocardium has been shown to be related to the severity of coronary artery disease. Reduced pH increases the oxidation of low-density lipoprotein that is considered to have a significant role in atherogenesis. According to the acidity theory of atherosclerosis the acidosis evoked by sympathetic dominance or continuous stress leads to changes in shear stress, the final stage in the development of atherosclerotic lesions. The importance of mechanical forces such as those derived from changes in hemodynamic shear stress, as a decisive factor for atherosclerosis, was advocated by Meyer Texon since1957.

The link between atherosclerosis and Alzheimer’s disease

Current evidence from pathological, clinical and epidemiological studies indicates that there is an association of Alzheimer’s disease (AD) and atherosclerotic disease, through a chronically lowering brain hypoperfusion.

Indeed, recent studies have shown that severe increase of carotid intimal medial thickness may be considered as a marker factor of progression of the cognitive decline in AD, and that intervention to reduce atherosclerosis may help to prevent onset of vascular dementia (VaD) and AD (1,2,3)

Anyway, we should take in account that vascular dementia and AD have different pathological origins with AD linked to low blood pressure and vascular dementia to high blood pressure (4).

Jack C de la Torre, one of the developers of the vascular hypothesis (5), in a recent study (6) has implicated many other possible cardiovascular risk factors beyond coronary artery disease, in the development of cognitive impairment preceding AD. Among these risk factors he cites: atrial fibrillation, thrombotic events, hypertension, hypotension, heart failure, low cardiac index and vascular pathology.

In his list sounds paradoxical the inclusion of hypertension as one of the cardiovascular risks factors responsible for the development of cognitive decline before AD, taking hypoperfusion as the key factor. Although, he argues that many studies have implicated impaired cognitive function to hypertension in geriatric patients and that is known for some time that hypertension in the elderly is a potential risk factor for AD.

De la Torre says that what is still not clear is precisely how hypertension increases the incidence of AD, particularly in those not treated with antihypertensives. His theory is that chronic brain hypoperfusion generated by increased vascular resistance from hypertension may be a key factor linking high blood pressure and AD.

However, even that various studies have reported that high blood pressure in midlife may increase the risk for late-life cognitive impairment, white matter lesions, clinical dementia and neuropathological markers of AD (7, 8), there are some contradictory findings about the role of hypertension in AD, like:

a)     A meta-analysis of longitudinal studies has shown no significant difference in incidence of AD between subjects with and without antihypertensive medication use (9).

b)    A review by Cochrane Database tells that there is no convincing evidence from the trials identified that blood pressure lowering in late-life prevents the development of dementia or cognitive impairment in hypertensive patients with no apparent prior cerebrovascular disease (10).

c)     The prevalence of midlife hypertension is lower in patients with AD compared to subjects without AD (11)

What sparked my interest regarding Alzheimer’s disease and its association with atherosclerosis / cardiovascular disease was a recent report by Medical News Today (12) informing that the use of beta-blockers for the treatment of hypertension resulted in fewer Alzheimer’s type brain lesions on autopsy than the use of other hypertensive medications.

This study involved 774 elderly Japanese-American men who took part in the Honolulu-Asia Aging Study (8). Autopsies were performed after the death of the participants. Of the 774 men, 610 had high blood pressure or were being treated with medication for high blood pressure. Among those who had been treated (about 350), 15 percent received only a beta blocker medication, 18 percent received a beta blocker plus one or more other medications, and the rest of the participants received other blood pressure drugs.

They found that all types of blood pressure treatments were clearly better than no treatment. However, men who had received beta blockers as their only blood pressure medication had fewer abnormalities in their brains compared to those who had not been treated for their hypertension, or who had received other blood pressure medications. The brains of participants who had received beta blockers plus other medications showed an intermediate reduction in numbers of brain abnormalities.

These included two distinct types of brain lesion: those indicating Alzheimer’s disease, and lesions called microinfarcts, usually attributed to tiny, multiple, unrecognized strokes. Study participants who had taken beta blockers alone or in combination with another blood pressure medication had significantly less shrinkage in their brains (13, 14).

My interest on the matter has even increased when I read the interview by Dr. White, one of the authors, to Heartwire (15):

-- Speculating on the mechanism, White noted that beta-blockers reduce pulse rate, which might have an effect on small-vessel microinfarcts in the brain. "Lifelong exposure of the pulse pressure in the brain might cause some damage," he said. "While we thought beta-blockers may reduce brain microinfarcts, which they did, we actually saw a larger reduction in the Alzheimer's-type lesions, which we had not expected. This is somewhat of a mystery at present and may be a chance finding. But if it is a real effect, I would think it was something to do with autonomic function." White suggested that a reasonable next step could be to test this hypothesis in mice genetically engineered to produce these Alzheimer's lesions. "If we treat these mice with beta-blockers and they develop fewer lesions, then we will know that it is an effect of the drugs," he commented. –

Moreover, I see some convergence between White’s interpretations and our concepts that the autonomic nervous system dysfunction, with sympathetic dominance, is the primary factor in the cascade of events leading to atherosclerosis, according the acidity theory developed by us in 2006. On the other side beta-blockers have sympatholytic effects that led to a reduction in the progression of atherosclerotic plaques in many studies. The use of sympatholytics might offer some benefits to AD in this sense (16).

So, we searched for papers about autonomic dysfunction and beta-blockers use in Alzheimer’s disease.

Regarding autonomic dysfunction I found many studies showing this relationship, with the indication of increased sympathetic activity and decreased parasympathetic activity in patients with Alzheimer’s disease (17-25). I also noticed about a recent hypothesis stating that elevated endogenous brain norepinephrine may be an etiological factor in some cases of AD, both before and during disease progression (26).

In fact, a recent study found that baroreflex function is reduced in Alzheimer’s disease (27). Impaired baroreflex sensitivity may activate the sympathetic nervous system (28).

The first study demonstrating some benefit of beta-blockers use in senile dementia occurred when six patients exhibiting severe disruptive behavior were effectively treated with propranolol which controlled this condition in all cases, without the need of inducing general sedation (29).

More recently, a large population-based study of persons 65 years and older reported that the use of antihypertensive medications, including beta-blockers, significantly lowered the risk of AD (30). In a subsequent analysis of the Cache Count study of individuals with incident AD, the participants taking beta-blockers – mostly patients with angina - experienced 40% decrease in rate of functional decline compared to those not taking beta-blockers (31).

In fact there is an indication through a recent retrospective database study about a possible protective effect of some antihypertensive agents (beta blockers and ACE inhibitors) on the development of dementia (32)

Also, animal experiments using the beta-blocker carvedilol found that it interferes with neuropathologic, biochemical and electrophysiological mechanisms underlying cognitive deterioration in AD supporting the potential development of carvedilol as a treatment for AD. In other publication the same group says that their results suggest that carvedilol reestablishes basal synaptic transmission, enhances neuronal plasticity and suppresses neuronal hyper-excitability in mice (33, 34).

Despite its beneficial effects in reduction of the progression of atherosclerotic plaques and possible positive actions directly in the brain, the use of beta-blockers may carry some risks that were reported in recent studies, for example:

a)     The effect of betablockers as a treatment for primary hypertension has been questioned. In a meta-analysis study published at Lancet Journal in 2005 the authors say that the effect of betablockers compared to placebo is less than optimum, with no difference for myocardial infarction but with a raised risk of stroke (35). By the way, hypertension is a highly prevalent risk factor for stroke.

b)    A recent study confirm that the use of beta blockers do not appear to be of any benefit in three distinct groups of stable outpatients: those with coronary artery disease but no history of MI; those with a remote history of MI (one year or more); and those with coronary risk factors only (36).

c)     Moreover in a randomized trial study published in Lancet Journal in 2008 the authors say that there were more deaths in the metoprolol group than in the placebo group in patients undergoing non-cardiac surgery (129 versus 97 patients) (37).

d)    Finally, a new meta-analysis suggests that beta-blockers have little effect in heart-failure patients with atrial fibrillation (38). Beta-blockers have been a cornerstone of the treatment of heart failure and are recommended for both HF and AF treatment, albeit for different indications. In HF recommendations, beta-blockers are indicated as standard therapy for all patients to reduce morbidity and mortality, paradoxically, even in systolic heart failure that is caused by reduced cardiac contractility that results in inadequate cardiac output.

So, while betablockers may be seen useful in atherosclerosis and in other diseases its poor results in the clinical situations cited above might be related to their effects of generalized hypocontractility, as advocated by Mesquita and colleagues since 1979 (39).

The decreased myocardial contractility caused by the use of beta-blockers deserves further researches not only to confirm if the negative inotropism is the real culprit for the poor results achieved by these drugs as well to  look for other sympatholytic drugs that will help the brain without depress the heart. 

Carlos Monteiro


An alternative sympatholitic that should deserve a further research for the treatment of hypertension and atherosclerosis should be digoxin at low dosage that might offer some beneficial effect in lowering the risk for dementia and AD (16).

Digoxin that was used effectively in heart failure, atrial fibrillation, in some arrhythmias and in coronary myocardial disease would in our view help the brain without depress the heart. By the way,digoxin treatment at low doses (< or = 0.125 mg/d) is likely to result in low serum concentrations of 0.5 - 09 ng/ml (40). Gheorghiade M et al, in a retrospective analysis of data from the DIG trial also have indicated a beneficial effect of digoxin on morbidity and no excess mortality in women at serum concentrations from 0.5 to 0.9 ng/ml, whereas serum concentrations > or =1.2 ng/ml seemed harmful (41)

High carbohydrate diets significantly activate SNS, while proteins and fats don't

Many studies are suggesting that high-carbohydrate diets, particularly in the form of high-glycemic index load, may activate the sympathetic nervous system with deleterious effects to human health (1). On the other side protein or fat ingestion have no significant sympathoexcitatory effect (2,3,4).

Also, the sympathetic activation have been linked in several studies to obesity, hypertension, insulin resistance, diabetes, and even atherosclerosis (5, 6, 7)

If the above studies are right, continuing to give support to high carbohydrate diets is both a wrong choice as well a bad advice.

Why alcoholics have a lower risk for coronary heart disease

The Spanish EPIC cohort study (European Prospective Investigation into Cancer), published in 2010, including 15630 men and 25808 women, has concluded that alcohol intake (moderate, high and very high consumption) in men aged 29–69 years was associated with a more than 30% lower CHD incidence (1).

Reading an old article by Leary (2) from 1935, I see that his interest in arteriosclerosis arose out of information that a class persons suffering from alcoholism appeared to show a lesser degree of atherosclerosis than their ages would justify. So, I have searched for recent papers that could confirm this relationship and found a study from 1997 comparing a
cohort of alcoholics who underwent a medico-legal autopsy during a five-year period with non-alcoholic controls who did not differ from the alcoholics in selection criteria. This study has show in the examinations, that alcoholic men and old women had a significantly lower degree of atherosclerosis in the coronary arteries (3)

A paper published in 2002 may have the answer to why alcoholics have a significantly lower degree of atherosclerosis in the coronary arteries and risk for coronary heart disease (4). Regarding this paper, a release from EurekAlert (5), with an interview by William Lovallo, one of the authors, told that:

“Before testing alcoholics for their responses to a public-speaking task, researchers first needed to establish if their sympathetic nervous system was able to respond at all. "This would tell us if their blunting was specific to psychological stressors like public speaking," said Lovallo, "or due to a generalized autonomic deficit."

He and his colleagues examined 20 alcohol-dependent subjects, abstinent for 21 to 28 days, and 10 age-matched nonalcoholics. All subjects were males between the ages of 22 and 55 years. The researchers used impedance cardiography and dinamap blood pressure monitoring to assess the participants' heart rate, stroke volume, cardiac output, total peripheral resistance, mean arterial pressure, systolic blood pressure, and diastolic blood pressure during orthostasis and public speaking. Self-reported mood was also assessed during these two tasks.

Cardiovascular responses to orthostasis were similar for the two groups. However, the alcoholics had blunted heart-rate responses to public speaking even though they reported similar anxiety responses to the nonalcoholics. This suggests a disconnection between perception of threat and resulting physiological responses among the alcoholics.

"The similar cardiovascular responses to orthostasis among the alcohol-dependent patients indicate that their autonomic nervous systems were working normally," said Lovallo. "Yet when we asked them to prepare and memorize a short speech and then deliver the speech to a video camera, the patients reacted with little or no change in heart rate, and of course, they failed to have a cortisol response. The patients reacted as if the social challenge of public speaking had no special meaning for them. So, the sympathetic nervous system in the patients looked normal, but their response to a psychological stressor was almost absent. When faced with a socially meaningful stressor, neither part of their fight-flight mechanism was working."

These results support the concept of the acidity theory where sympathetic predominance is the primary factor leading to atherosclerosis (6)

A review from the book "Acidity Theory of Atherosclerosis: New Evidences", 2012 (Paperback)

Think that fat causes heart disease? Think again!

By Zoe V. Harcombe* Review at Amazon

This must be the academic equivalent of the "Collection of short stories" format so popular in the fiction world. It's a collection of articles, all different, but related by a common theme - heart disease.

I really enjoyed the format - it gives a taste of each topic without going into massive detail on each. The comprehensive references point the way if you want to know more about any particular factor in coronary artery disease. I never knew that the condition of having Down syndrome seems to have some protective properties when it comes to heart disease. What about the role of bacteria, or lactic acid? Is erectile dysfunction trying to tell us something? More familiar topics, such as smoking and stress, are covered but in a really new and often surprising way. I lost count of the number of times I learned something new or saw a well known topic covered in an innovative way.

I like the way the author thinks and challenges everything and makes connections between seemingly unrelated things. I also liked the inputs from colleagues - for example David Diamond's contribution to the article "Is LDL unquestionably and unequivocally a causal risk factor for heart attack?" The role of glucose (not fat) in the working of the body was fascinating and should be far more widely known.

You cannot fail to learn something if you read this book. If you are interested in our number one killer of humans - men especially - this is well worth your time.
