6 Interestingly, over the past dozen years or so since the Human Genome Project began, about $3 billion has been spent to complete the sequencing or about $1 per base pair.
7 The completion of the Human Genome Project occurred in the “fiftieth anniversary year of the discovery of the double-helical structure of DNA. . . . The genomic era is now a reality.” F. S. Collins et al. 2003. “A vision for the future of genomics research.” Nature. Apr 24;422: 835–847. To celebrate, entire issues of the major scientific journals Nature and Science were dedicated to discussions of the implications. For more information, see the Human Genome Project Information site (www.ornl.gov/TechResources/
Human_Genome/project/50yr.html).
Among the challenges is applying the lessons learned from the Human Genome Project to understanding thousands of other organisms. See, for example, M. E. Frazier et al. 2003. “Realizing the potential of the genome revolution: the Genomes to Life Program.” Science. 300: 290; F. S. Collins, M. Morgan, and A. Patrinos. “The Human Genome Project: lessons from large-scale biology.” Science. 300: 286. See also M. Ridley. 1999. Genome: The Autobiography of a Species in 23 Chapters. New York: Perennial.

11 Each chip contains synthetic oligonucleotides that replicate sequences that identify specific genes. “To determine which genes have been expressed in a sample, researchers isolate messenger RNA from test samples, convert it to complementary DNA (cDNA), tag it with fluorescent dye, and run the sample over the wafer. Each tagged cDNA will stick to an oligo with a matching sequence, lighting up a spot on the wafer where the sequence is known. An automated scanner then determines which oligos have bound, and hence which genes were expressed.” E. Marshall. 1999. “Do-it-yourself gene watching.” Science. Oct 15;286(5439): 444–447.

17 Pima Indians in Arizona maintained their traditional way of life until the late 19th century. Then farmers diverted their water supply, resulting in many relying on the lard, sugar, and white flour provided by the government. During World War II, many Pimas entered military service or migrated to cities
to work in factories. Though many Pimas returned to the reservations in the 1950s, their way of life
was “profoundly affected.” See “Obesity associated with high rates of diabetes in the Pima Indians,” http://diabetes.niddk.nih.gov/dm/pubs/pima/obesity/obesity.htm.
According to a recently published theory, the reason only 2 percent of Europeans suffer from diabetes is that a diabetes epidemic centuries ago killed many people and prevented them from passing on the gene. Other populations, particularly indigenous peoples, carry the genes that make them highly prone to the risk factors found in urbanized settings. This is one reason 50 percent of Native Americans have diabetes. J. Diamond. 2003. “The double puzzle of diabetes.” Nature. Jun 05;423: 599–602. See also D. L. Coleman. 1978. “Diabetes and obesity: thrifty mutants?” Nutr Rev. May;36(5): 129–132.

24 Lifetime risk of developing breast cancer in women who test positive for the BRCA 1 mutation has been estimated at 80 percent, while lifetime risk for noncarriers is about 10 percent. See J. M. Lancaster. 1997. “BRCA 1 and 2—A Genetic Link to Familial Breast and Ovarian Cancer.” Medscape Women’s Health. Feb;2(2): 7. Other studies cite a 92 percent total lifetime risk.
In one Dutch study, 50 percent of healthy women whose mothers had breast cancer refused testing for BRCA1, preferring not to know whether they harbored such a potent cancer risk. The National Center for Technology Information (www.ncbi.nlm.nih.gov/entrez/dispomim.cgi?id5113705), with Johns Hopkins University, has summarized studies conducted on the BRCA gene.

27 Some studies are focusing on the patterns of variations in apolipoproteins across populations. Their focus is to determine “the usefulness of apolipoproteins as genetic markers for clinical, population, and anthropological studies.” P. P. Singh, M. Singh, and S. S.

16 The best vegetarian source of preformed EPA is wakame, a type of seaweed that contains 186 mg of EPA per 100 grams of seaweed. Yet vegans and vegetarians are still advised to supplement with flaxseed oil, because to obtain 650 mg of EPA, the minimum daily requirement, over 12 ounces of wakame a day would be needed.

25 Chronic NSAID use is associated with a very high incidence of adverse drug reactions, such as gastrointestinal hemorrhage. Over 16,500 deaths and 100,000 hospitalizations annually have been associated with prescription NSAID usage (and the number would be even higher if over-the-counter usage were included). See M.

Chapter 13
1 The risk of defective homocysteine metabolism rises with age and varies with ethnicity; hence the wide spread between 10 and 44 percent. See G. L. Booth and E. E. Wang. 2000. “Preventive health care, 2000 update: screening and management of hyperhomocysteinemia for the prevention of coronary artery disease events. The Canadian Task Force on Preventive Health Care.” CMAJ. Jul 11;163(1): 21–29.
2 Medicare does not pay for homocysteine testing, regarding it as neither medically reasonable nor necessary. Although controversial, we feel that by paying a few tens of dollars for routine homocysteine screening, it would help identify many individuals at significant risk of heart attack, stroke, and Alzheimer’s diseases that Medicare then pays tens of thousands of dollars to treat.
3 In the same paragraph on their Web site that the American Heart Association doesn’t acknowledge homocysteine as a “major risk factor for cardiovascular disease,” they also “don’t recommend widespread use of folic acid and B vitamin supplements to reduce the risk of heart disease and stroke.” See www.
americanheart.org/presenter.jhtml?identifier54677. See also, M. R. Malinow et al. 1999. “Homocyst(e)ine, diet, and cardiovascular diseases: a statement for healthcare professionals from the Nutrition Committee, American Heart Association.” Circulation. 99: 178–182.
4 Any product containing more than 800 mcg of folic acid requires a prescription.
5 More precisely, cytosine first undergoes another chemical reaction known as “deamination” to form uracil, which is then methylated to form thymine.
6 J. Yokota et al. 2003. “Genetic alterations responsible for metastatic phenotypes of lung cancer cells.” Clin Exp Metastasis. 20(3): 189–193. According to this study, one gene associated with lung cancer is “inactivated in 50% of lung cancers by deletions, mutations, and methylation.” See also K. S. McCully. 1994. “Chemical pathology of homocysteine. II. Carcinogenesis and homocysteine thiolactone metabolism.” Ann Clin Lab Sci. Jan–Feb;24(1): 27–59.

Many other studies have also shown such a connection. For example, an Irish study showed a fivefold increase in the risk of stroke with elevated homocysteine levels. The lead author suggested that the unavailability of fortified foods, particularly cereals, in the United Kingdom made supplementation even more important. S. P. McIlroy et al. 2002. “Moderately elevated plasma homocysteine, methylenetetrahydrofolate reductase geneotype, and risk for stroke, vascular dementia, and Alzheimer disease in Northern Ireland.” Stroke.

12 R. Clarke et al. 1998. “Folate, vitamin B12, and serum total homocysteine levels in confirmed Alzheimer disease.” Arch Neurol. Nov;55(11): 1449–1455.
13 While elevated homocysteine confers a cardiovascular risk equal to smoking, the combination is even worse. One study “suggests that smokers with high plasma homocysteine are at greatly increased risk of cardiovascular disease and should therefore be offered intensive advice to help them cease smoking.” P. O’Callaghan et al. 2002. “Smoking and plasma homocysteine.” Eur Heart J. Oct;23(20): 1580–1586; S. Tonstad and P.

NOVA Online (www.pbs.org/wgbh/nova/ice/greenhouse.html) provides useful background: “Greenhouse gas concentrations in the atmosphere have been naturally rising and falling for billions of years, creating cold and warm periods in the Earth’s history. For example, as the Ice Age progressed, scientists believe the amount of natural carbon dioxide in the atmosphere dropped over thousands of years, reducing the greenhouse effect, and making the Earth cooler. But many disagree on how that change in carbon dioxide occurred. Today, scientists are looking at effects of global warming as they debate the long-term impact of man-made carbon dioxide and CFCs entering the atmosphere. Many climatologists argue that we are artificially increasing the greenhouse effect, warming the Earth faster than would occur naturally, which could cause problems for the Earth in the future.”

35 A 2001 report by U.S. PIRG (the national lobbying office for the state Public Interest Research Groups, which are nonprofit, nonpartisan public interest advocacy groups) and the Environmental Working Group found that mercury contamination of fish is so great that 25 percent of pregnant women who eat fish regularly expose their unborn babies to levels of mercury that could threaten a developing fetus. The situation will only get worse with full enactment of the Bush administration’s “Clear Skies Initiative,” which would allow three times more mercury pollution than full enforcement of the current Clean Air Act.
36 Farm-raised salmon are fed fish food containing high levels of pollutants. Unlike wild ocean salmon that consume phytoplankton, which they then turn into EPA, farm-raised salmon have little EPA. A recent report by the Environmental Working Group suggests farmed salmon may also be high in PCBs due to contamination of their food (www.ewg.org/news/story.php?id51871).

2 Even though women’s comparable risk trails that of men by 10 years, “more than half of persons who die each year of heart disease are women.” “Chronic Disease Overview,” op. cit. Also, “38 percent of women compared to 25 percent of men will die within one year after a heart attack.” “Statistics You Need to Know,” American Heart Association (www.americanheart.org/presenter.jhtml?identifier5107).
3 In the United States, for example, approximately 75,000 bypass surgeries were performed in
1979 and over 520,000 in 2000. Angioplasties were first tracked by the AHA in 1986; by 2002, close to 570,000 were performed per year in the United States. “Trends in Cardiovascular Operations and Procedures,” in “2003 Heart Disease and Stroke Statistical Update,” American Heart Association (www.americanheart.org/presenter.jhtml?identifier53009972). See also A. Michaels and K. Chatterjee. 2002. “Angioplasty versus bypass surgery for coronary artery disease.” Circulation. Dec 3;106(23):187–190.
4 Recent data suggest that the volume of cases handled by the hospital and the surgeon in particular has an impact on the mortality rate from bypass surgery. See E. L. Hannan et al. 2003. “Do hospitals and surgeons with higher coronary artery bypass graft surgery volumes still have lower risk-adjusted mortality rates?” Circulation. Aug 19;108(7):795–801.
5 Public information materials often claim that the mental decline is temporary; see, for example, “Coronary bypass surgery,” MayoClinic.com (www.mayoclinic.com/invoke.cfm?id5HB00022). However, recent research has found “early improvement followed by later decline”; see, for example, M. F. Newman et al. 2001. “Longitudinal assessment of neurocognitive function after coronary-artery bypass surgery.” N Engl J Med. Feb 8;344(6):395–402.
6 Bypass surgery and angioplasty cannot fix the injured heart tissue or the microvessel obstructions that are most likely to cause post-heart-attack complications. Johns Hopkins Magazine, April 1998, “Treating heart attacks through MRI,” www.jhu.edu/~jhumag/0698web/health.html. This study showed a higher risk of death for patients with invasive treatment: L. F. Wexler et al. 2001. “Non-Q-wave myocardial infarction following thrombolytic therapy: a comparison of outcomes in patients randomized to invasive or conservative post-infarct assessment strategies in the Veterans Affairs Non-Q-Wave Infarction Strategies In-Hospital (VANQWISH) Trial.” J Am Coll Cardiol. Jan;37(1):19–25.
In this study, patients treated invasively experienced less angina but significantly more critical events, including death. H. C. Bucher et al. 2000. “Percutaneous transluminal angioplasty versus medical treatment for non-acute coronary heart disease: meta-analysis of randomized controlled trials.” BMJ. Jul 8;321(7253): 73–77. Another study showed many repeat operations in patients treated invasively and a 22-year cumulative survival rate of 20 percent in the surgically treated group compared with 25 percent in the medically treated group. “This trial provides strong evidence that initial bypass surgery did not improve survival for low-risk patients and that it did not reduce the overall risk of myocardial infarction.” P. Peduzzi, A. Kamina, and K. Detrie. 1999. “Twenty-two-year follow-up in the VA Cooperative Study of coronary artery bypass surgery for stable angina.” Am J Cardiol. Jan 15;83(2): 301–304.
In yet another study, “patients undergoing coronary angioplasty had twice the rate of adverse outcomes as normal subjects, seven times the rate of angina, almost four times the number of heart attacks and twice the rate of congestive heart failure.” G. A. Van Norman and K. Posner. 2000. “Coronary stenting or percutaneous transluminal coronary angioplasty before noncardiac surgery increases adverse events: the evidence is mounting.” J Am Coll Cardiol. Dec;36(7): 2351–2352 (as described on the Noninvasive Heart Center site, www.heartprotect.com/comparison-studies.shtml). See also note 7 below and note 82 on page 418.
7 Note 6 above cites several studies that show improved outcomes for treatment with medication as compared to treatment with surgery. Two studies that show a slightly better outcome with surgery are: C. Espinoza-Klein et al. 2000. “Ten-year outcome after coronary angioplasty in patients with single-vessel coronary artery disease and comparison with the results of the Coronary Artery Surgery Study (CASS).” Am J Cardiol. Feb 1;85(3): 321–326. This study showed relative rates of survival after 10 years was 86 percent after balloon angioplasty, 85 percent after bypass surgery, and 82 percent with medical treatment alone.
M. M. Graham et al. 2002. “Survival after coronary revascularization in the elderly.” Circulation. May 21: 105(20): 2378–2384. This study showed 17 percent better survival in older patients (greater than 80 years old) who had surgery versus those who did not. This study also showed a small survival increase in patients under 70 years old who had surgery versus those who did not (95 percent versus 91 percent).
Studies have shown that angioplasty improves survival when applied during a heart attack to clear away the thrombus (blood clot).
Additional studies on treatment with medication include the following:
R. Conti. 1999. “Single-Vessel Disease: What is the Evidence Favoring Medical Versus Interventional Therapy?” Clin. Cardiol. 22, 3–5 (1999) at www.clinicalcardiology.org/briefs/9901briefs/22-003.html; “Treatment with a combination of statin and niacin can slash the risk of a fatal or non-fatal heart attack or hospitalization for chest pain by 70 percent among patients who are likely to suffer heart attacks and/or death from coronary heart disease, according to a study by University of Washington researchers in the Nov. 29 New England Journal of Medicine.”; B.

9 In addition to the new model of heart disease presented in the next section, another primary reason for the failure of invasive procedures is that these procedures address symptoms of the problem, not the problem itself. “There is a common misconception that most of the excess risk accumulated over many years can be erased by aggressive short-term prevention introduced later in life.” S. Grundy et al. 1999. “Assessment of cardiovascular risk by use of multiple-risk-factor assessment equations.” Circulation. 100: 1481–1492. The importance of behavioral changes in preventing future cardiovascular events and mortality has been shown by many studies, including N. C. Campbell et al. 1998. “Secondary prevention in coronary heart disease: a randomized trial of nurse-led clinics in primary care.” Heart. Nov;80(5): 447–452. With regard to the elderly, see last reference in note 7 above.
“Insulin resistance with or without frank type 2 diabetes has emerged as a major determinant of accelerated coronary artery disease and its sequelae.” Thus, a number of randomized clinical trials have been performed to compare the efficacy of these procedures for diabetic patients who fall into the subset of patients with severe multivessel disease who benefit from surgery.

27 The role of iron in atherosclerosis is still controversial. Some studies support such a role: “These results provide direct evidence for a key role of iron in initiating atherogenesis” (D. Ponraj et al. 1999. “The onset of atherosclerotic lesion formation in hypercholesterolemic rabbits is delayed by iron depletion.” FEBS Lett. Oct 8;459(2): 218: 222). Others do not: “Overall the results do not support the hypothesis that positive body iron stores, as measured by serum ferritin, are associated with an increased risk of cardiovascular diseases (CVD), coronary heart disease (CHD), or myocardial infarction (MI) . . . ” (C.

Dropping calcium from the diet will not reduce your calcium score. “It’s not the milk you’re drinking that’s causing the problem,” says Dr. Larry Dean, professor of medicine at the University of Washington Medical Center. “It’s the butterfat in the milk that’s causing the cholesterol problem, which is then causing the inflammatory process in the blood vessels. The calcium is a marker of the underlying disease process” (quoted in “Calcium scoring: A new technique useful for some with heart risk factors,” University Week, University of Washington. Vol. 19(25), May 2, 2002; (www.depts.washington.edu/uweek/archives/
2002.05.MAY_02/hs_e.html).
36 Calcium scoring is a new technique used to help identify patients at risk of heart disease. A series of quick images of the heart taken by a computed tomography (CT) scanner allows doctors to “score” the level of calcium deposits in the coronary arteries. Numerous studies are now examining the relationship between high calcium scores and other risk factors in predicting illness. N. D.

47 A number of studies citing low cholesterol as a factor in hemorrhagic stroke have been reported widely (see, for example, www.cnn.com/HEALTH/9902/06/strokes/). According to the American Heart Association, these results should be considered cautiously: study sizes have often been small and no cause-and-effect mechanism has been identified. Furthermore, “there is no trend for an increase in total mortality unless the total cholesterol level is less than 160 mg/dL. It is estimated that in the United States less than 10% of middle-aged men and women have serum cholesterol levels below this range.” M. Criqui. 1994. “A statement for healthcare professionals from the American Heart Association Task Force on Cholesterol Issues” (www.americanheart.org/presenter.jhtml?identifier51208).
48 T. Partonen et al. 1999. “Association of low serum total cholesterol with major depression and suicide.” Br J Psych. 175: 259–262.
As with the link to stroke, however, some researchers are cautious about results that might deter clinicians from “prescribing cholesterol-lowering drugs, to reduce the risk of death from coronary heart disease.” “Many confounding factors, e.g., poor health, depression and loss of appetite may play a role in the apparent relationship between serum cholesterol levels and suicide.” R. Manfredini et al. 2000. “The association of low serum cholesterol with depression and suicidal behaviors: new hypotheses for the missing link.” J Int Med Res. Nov 1;28(6): 247–257.

content/abstract/NEJMoa040583). The research compared the experimental group, which took 80 mg per day of Lipitor, to the control group, which took 40 mg a day of Pravachol. The LDL-C comparison was 62 for the experimental group versus 95 for the control group. The experimental group had substantially fewer heart attacks and recommendations for surgery.
50 HDL2 and HDL3 are the two major HDL subclasses. See, for example, M. C. Bakogianni et al. 2001. “Clinical evaluation of plasma high-density lipoprotein subfractions (HDL2, HDL3) in insulin-dependent diabetics with coronary artery disease.” J Diabetes Complications. Sep–Oct;15(5): 265–269.
Regarding the debate over the more protective subfraction, see, for example, “Antioxidative activity of HDL subfractions increased with increment in density, as follows: HDL2b <HDL2a <HDL3a <HDL3b <HDL3c . . . ” A. Kontush et al. 2003. “Small, dense HDL particles exert potent protection of atherogenic LDL against oxidative stress.” Arterioscler Thromb Vasc Biol, published online before print, August 14, 2003.
In addition, “from a statistical standpoint, the present data suggest that the HDL2 subfraction may be more closely related to the development of IHD than the HDL3 subfraction. However, the qualitative difference in the relative predictive value of each subfraction was trivial, since it only corresponded to a modest quantitative difference. Thus, the possibility that a significant proportion of the cardioprotective effect of elevated HDL cholesterol levels may be mediated by the HDL3 subfraction still cannot be excluded.” B. Lamarche et al. 1997. “Associations of HDL2 and HDL3 subfractions with ischemic heart disease in men: Prospective results from the Quebec Cardiovascular Study.” Arterioscler Thromb Vasc Biol. Jun 1;17(6): 1098–1105.
51 A number of recent news stories have highlighted the importance of cholesterol tests “that look
beyond the usual definitions of good and bad cholesterol, that separate the bad from the really bad and
the mildly good from the angelic.” D. Franklin. 2001. “What this CEO didn’t know about his cholesterol almost killed him.” Fortune, March 19 (and reported on www.berkeleyheartlab.com/GENERAL/news_
fortune.html).
52 LDL particle size and density gained attention in the early 1990s, when their role in heart disease was uncovered (see R. M. Krauss et al. 1994. “A prospective study of LDL particle diameter and risk of myocardial infarction.” Circulation. 90:I–460; described in D. Gilbert. 1994. “Small dense cholesterol particles worse for your heart.” November 29, www.lbl.gov/Science-Articles/Archive/cholesterol-pArticles.phpl). See also P. T. Williams et al. 2003. “Smallest LDL particles are most strongly related to coronary disease progression in men.” Arterioscler Thromb Vasc Biol. Feb 1:23(2): 314–321; and note 39 on page 415.
53 At a 1999 colloquium, R. M. Krauss, a researcher at the E. O. Lawrence Berkeley National Laboratory, explained: “Small LDL bind more tightly to the artery wall, they are oxidized more rapidly and they may cause greater endothelial dysfunction. There is an increasing body of evidence that suggest that some of the damage caused by higher levels of triglyceride is mediated by this effect on LDL, as well as some of the other metabolic conditions that are associated with high triglyceride, including low HDL and insulin resistance. We call this an atherogenic phenotype. It is a collection of abnormalities that together comprise a real significant coronary disease risk profile that is above and beyond what we can detect just by measuring the levels of LDL.” Sante Fe Colloquium on Preventive Cardiovascular Therapy, October 7–9, 1999; Sante Fe, New Mexico (www.acc.org/education/online/sante_fe/krauss.htm).
R. Krauss is also an author on a study that supports triglycerides as an independent risk factor for myocardial infarction. See M. J. Stampfer et al. 1996. “A prospective study of triglyceride level, low-density lipoprotein particle diameter and risk of myocardial infarction.” JAMA. Sep 18;276(11): 882–888.
54 “Policosanol is a mixture of higher primary aliphatic alcohols isolated from sugar cane wax, whose main component is octasanol.

Berthold. 2002. “Policosanol: clinical pharmacology and therapeutic significance of a new lipid-lowering agent.” Am Heart J. Feb;143(2): 356–365.
55 Ibid. “Because higher doses have not been tested up to now, it cannot be excluded that effectiveness may be even greater. Daily doses of 10 mg of policosanol have been shown to be equally effective in lowering total or LDL cholesterol as the same dose of simvastatin or pravastatin. Triglyceride levels are not influenced by policosanol.”

63 For the different types of drugs for hypertension and how they work, see the list on the American Heart Association site: “Blood pressure-lowering drugs” (www.americanheart.org/presenter.jhtml?

One study observed that losartan (Cozaar) had fewer side effects than calcium channel blockers in a community-based setting, which meant that patients would be more likely to adhere to their treatment regimens (J. P. Grégoire et al. 2001. “Tolerability of antihypertensive drugs in a community-based setting.” Clin Ther. May;23(5): 715–726). Another research compared angiotensin II antagonists and calcium channel blockers and suggested a role for each. (M.

73 Contradictory results have been reported on the link between periodontal disease and coronary heart disease. P. P. Pussinen et al.

80 No significant differences in outcome were noted between:
Veterans treated medically and surgically (R. J. Scott et al. 1987. “Comparison of medical and surgical treatment for unstable angina pectoris.” N Engl J Med. Apr 16;316(16): 977–984).
Hospitalized patients in Sweden receiving dramatically less surgical intervention than in the U.S. (P. G. McGovern et al. 1997. “Comparison of medical care and one and 12-month mortality of hospitalized patients with acute myocardial infarction.” Am J Cardiol. Sept 1;80(5): 557–562).
Patients in different parts of the U.S. receiving radically different types of care (L. Pilote et al. 1995. “Regional variation across the United States in the management of acute myocardial infarction.” N Engl J Med. Aug 31;333(9): 589–590).
At the same time, significant differences in outcome have been associated with better oversight of patients and lifestyle changes. Note, however, that the selection of patients can influence the results from comparative studies. Studies that screen out sicker patients will inevitably show fewer differences between surgical and medical treatment.

Prevention of progression of this disease requires changing the metabolic milieu of the patient who has it. Interventional procedures are superb for alleviating the current ischemia and related symptoms, but a concerted effort by the healthcare team and the patient are necessary to change the ultimate outcome.
