      &lt;p&gt;It is rare that a simple matter of patient choice causes an international flap.&lt;/p&gt;
&lt;p&gt;But that&apos;s what happened when 60-year-old Danny Williams of St. John&apos;s, Newfoundland, decided to go to the U.S. for heart surgery.&lt;/p&gt;
&lt;p&gt;That&apos;s because Williams isn&apos;t just any old Newfoundlander  --  he&apos;s the premier of Canada&apos;s easternmost province, the head of its government.&lt;/p&gt;
&lt;p&gt;The disclosure Tuesday that Williams was in an undisclosed location in the U.S., having an undisclosed procedure that he couldn&apos;t get in Newfoundland, brought catcalls from both sides of the border.&lt;/p&gt;
&lt;p&gt;The &lt;em&gt;New York Post&lt;/em&gt;, for instance, in an article headlined &quot;Oh (no), Canada&quot; used the news to take a whack at healthcare reform in the U.S. And the American Thinker blog  --  among many others  --  argued that Williams&apos; choice is evidence of the inferiority of Canada&apos;s &quot;technologically second-rate and rationed system.&quot;&lt;/p&gt;
&lt;p&gt;In Canada, cardiac specialists defended the premier&apos;s decision as a matter of choice and at the same time noted that  --  with few exceptions  --  most cardiac procedures are both available and done well in Canada.&lt;/p&gt;
&lt;p&gt;On the other hand, Newfoundland  --  with a population of about 500,000, less than Wyoming  --  is less well equipped. Doctors in the province do coronary artery bypass grafts (CABG) and other common procedures, but often send patients elsewhere in the country for transplants or rare operations.&lt;/p&gt;
&lt;p&gt;By way of contrast, doctors in Ontario  --  Canada&apos;s most populous province  --  handle more than 11,000 cardiac procedures a year in 11 specialized cardiac centers, according to Kori Kingsbury, CEO of Ontario&apos;s Cardiac Care Network.&lt;/p&gt;
&lt;p&gt;It&apos;s one of the places a Newfoundland patient might go if appropriate care wasn&apos;t available in that province, but Kingsbury said most of those 11,000-odd procedures are, in fact, performed on Ontario residents.&lt;/p&gt;
&lt;p&gt;Still, a &quot;handful&quot; of Ontario patients go to the U.S. every year for surgery, usually because they need emergency treatment and live close to the border, she told &lt;em&gt;MedPage Today&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;And every year, a few Americans cross the border the other way seeking care, she said, although she did not immediately have exact numbers.&lt;/p&gt;
&lt;p&gt;But for the most part, any required surgery can be obtained in a timely fashion in the province, Kingsbury said. In December, for instance, the median wait time for an elective isolated CABG was 14 days and urgent or emergency care was performed much more quickly.&lt;/p&gt;
&lt;p&gt;The exceptions to that rule are rare, complex procedures the experts in which reside in the U.S., according to cardiac surgeon Chris Feindel, MD, of Toronto&apos;s University Health Network.&lt;/p&gt;
&lt;p&gt;But the only nonexperimental example he can think of is repair of a rare aneurysm in the descending aorta, where the best care for the procedure is at Baylor University in Texas, Feindel told reporters.&lt;/p&gt;
&lt;p&gt;Because the condition is so rare, &quot;there&apos;s really no center across the country that has a large experience with these,&quot; he told the Canadian Press.&lt;/p&gt;
&lt;p&gt;In general, though, top-level cardiac care is readily available, according to Robert Roberts, MD, president of the University of Ottawa Heart Institute in the nation&apos;s capital.&lt;/p&gt;
&lt;p&gt;Roberts, who was head of cardiology at Baylor for 23 years before moving to Canada five years ago, said 99% of what can be done in the U.S. is done both routinely and well at his center.&lt;/p&gt;
&lt;p&gt;Premier Williams&apos; decision may have been influenced by the knowledge that Newfoundland does not fare as well as the rest of the country in some cardiac outcomes.&lt;/p&gt;
&lt;p&gt;According to the Canadian Institute for Health Information, the province has the highest rate of acute myocardial infarction, at 351 per 100,000 patients in 2007-2008.&lt;/p&gt;
&lt;p&gt;More revealing is the unplanned hospital readmission rate after a heart attack, which is regarded as a measure of quality of care. In 2007-2008, 6.2% of Newfoundland patients were readmitted, significantly higher than the national rate of 5.2%.&lt;/p&gt;
&lt;p&gt;And 30-day inhospital mortality  --  another marker of care quality  --  is also higher than the national average at 10.9% compared with 9.4%, the institute said.&lt;/p&gt;
&lt;p&gt;Kathy Dunderdale, the province&apos;s deputy premier, told reporters that Williams made the decision after weeks of consultation with his doctors and is expected make a full recovery.&lt;/p&gt;
&lt;p&gt;But she would not comment on his location or what procedure he needed, saying only that he could not get the care he needed in the province.&lt;/p&gt;
&lt;p&gt;A spokesman for the local health authority did not return telephone calls asking what procedures are not available in the province.&lt;/p&gt;
&lt;p&gt;Dunderdale also did not comment on who will pay for the surgery. Usually, if it&apos;s deemed medically necessary for a patient to travel outside the province for care, the taxpayer-funded medicare system picks up the tab.&lt;/p&gt;
&lt;p&gt;But Williams  --  sometimes known as &quot;Danny Millions&quot;  --  is personally wealthy, having made a fortune in cable television.&lt;/p&gt;

                     score="0.008"
                     href="http://www.medpagetoday.com/Cardiology/CHF/tb/18193?impressionId=1265729836845"
                     
      &lt;p&gt;Serial measurement of a natriuretic peptide predicted the risk of heart failure and cardiovascular death in older patients who were initially free of heart failure, data from a longitudinal cohort study showed.&lt;/p&gt;
&lt;p&gt;An increase of more than 25% in levels of N-terminal pro-B type natriuretic peptide (NT-proBNP) doubled the risk of heart failure and cardiovascular death. In contrast, a more than 25% decrease in NT-proBNP was associated with a greater than 40% reduction in the risk of both end points.&lt;/p&gt;
&lt;p&gt;&quot;NT-proBNP levels frequently change over time, and these fluctuations reflect dynamic changes in cardiovascular risk,&quot; Christopher R. deFilippi, MD, of the University of Maryland in Baltimore, and co-authors concluded in an article in the Feb. 2 issue of the &lt;em&gt;Journal of the American College of Cardiology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;&quot;This change in [NT-proBNP] level reflects a significant change in patient risk independent of cardiovascular risk factors, ejection fraction, or medication use,&quot; they added. &quot;Ultimately, NT-proBNP levels may guide further diagnostic testing or potential preventive measures to reduce the risk of developing heart failure or dying of cardiovascular disease.&quot;&lt;/p&gt;
&lt;p&gt;About 80% of cardiovascular deaths occur in older adults. Assessing cardiovascular risk in older patients is challenging because traditional cardiovascular risk factors are less predictive in older versus middle-age populations, the authors wrote.&lt;/p&gt;
&lt;p&gt;Subclinical cardiovascular disease is common among older adults and increases the risk of cardiovascular events, including heart failure. Repeated measures of traditional markers of cardiovascular disease in patients with subclinical disease are associated with increased risk compared with patients who remain free of identifiable disease, the authors continued.&lt;/p&gt;
&lt;p&gt;Levels of BNP and NT-proBNP are associated with long-term cardiovascular outcomes in the general population. However, the peptides&apos; ability to provide additional prognostic information beyond that of traditional risk factors remained controversial.&lt;/p&gt;
&lt;p&gt;To examine the prognostic value of NT-proBNP in an older population, deFilippi and colleagues analyzed data on 3,000 participants in the Cardiovascular Health Study. The authors hypothesized that NT-proBNP levels in an ambulatory population of older patients would independently predict new-onset heart failure and cardiovascular death.&lt;/p&gt;
&lt;p&gt;&quot;Furthermore, we anticipated that serial measurements of NT-proBNP, as a possible surrogate for change in subclinical disease status, identify a dynamic change in long-term risk of incident heart failure and cardiovascular mortality,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;Stored serum samples obtained at enrollment and two to three years later were used to measure NT-proBNP levels. Median follow-up for the cohort was 11.9 years.&lt;/p&gt;
&lt;p&gt;After separating the study group into quintiles of NT-proBNP levels, investigators found that patients with the highest baseline levels of the peptide (&amp;gt;267.7 pg/mL) had a threefold greater risk of new-onset heart failure (HR 3.05, 95% CI 2.46 to 3.78) and cardiovascular death (HR 3.02, 95% CI 2.36 to 3.86) compared with patients in the lowest NT-proBNP quintile (&amp;lt;47.5 pg/mL).&lt;/p&gt;
&lt;p&gt;The researchers identified 190 pg/mL as the NT-proBNP threshold for increased risk. Among study participants with baseline levels less than 190 pg/mL, an increase greater than 25% to a level above 190 pg/mL had a twofold increased risk of heart failure (HR 2.13, 95% CI 1.68 to 2.71) and cardiovascular death (HR 1.91, 95% CI 1.43 to 2.53) compared with participants whose NT-proBNP levels remained below 190 pg/mL.&lt;/p&gt;
&lt;p&gt;Among study participants with elevated baseline NT-proBNP levels, an increase greater than 25% also doubled the risk of heart failure (HR 2.06, 95% CI 1.56 to 2.72) and cardiovascular disease (HR 1.88, 95% CI 1.37 to 2.57).&lt;/p&gt;
&lt;p&gt;A decrease greater than 25% from baseline significantly reduced the risk of heart failure (HR 0.58, 95% CI 0.36 to 0.93) and cardiovascular death (HR 0.57, 95% CI 0.32 to 1.01) compared with participants whose baseline levels remained elevated.&lt;/p&gt;
&lt;p&gt;The investigators noted limitations of the study including the fact that a quarter of the participants did not have a follow-up blood sample and those who did were younger and had fewer cardiac risk factors.&lt;/p&gt;
&lt;p&gt;In addition, the length of follow-up could not account for differences in treatment over time, and the accuracy of NT-proBNP levels in samples as much as 20 years old cannot be assured.&lt;/p&gt;
&lt;p&gt;The study is noteworthy for highlighting the concept of dynamic risk assessment based on serial measurement of NT-proBNP, Richard W. Troughton, MB ChB, PhD, Matthew G. Daly, MB ChB, and Christopher M. Frampton, PhD, of the University of Otago in Christchurch, New Zealand, wrote in an editorial.&lt;/p&gt;
&lt;p&gt;&quot;The findings confirm a modest improvement in risk stratification by including a single measurement of NT-proBNP levels,&quot; they wrote &quot;The investigators take this a step further by showing that serial NT-proBNP measurement at a later time provides a further modest improvement in risk stratification.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Whether the improvement in risk stratification achieved by performing serial NT-proBNP testing crosses a threshold of definite clinical value needs further evaluation, with particular consideration of the cost-effectiveness of such a strategy,&quot; they added.&lt;/p&gt;

                     score="0"
                     href="http://www.medpagetoday.com/Pulmonology/SmokingCOPD/tb/18070?impressionId=1265729836845"
                     
      Chronic lung disease begins to affect cardiac function at even mild levels of emphysema, data from a large prospective cohort study showed.&lt;br&gt;
&lt;br&gt;A 10-point increase in percent emphysema by lung CT had a linear inverse relationship with left ventricular end-diastolic volume (LVEDV), stroke volume, and cardiac output (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001 for all parameters), researchers reported in the Jan. 21 issue of the &lt;em&gt;New England Journal of Medicine&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;Current smoking status increased the magnitude of the association compared with former smokers and nonsmokers, the researchers found.&lt;br&gt;
&lt;br&gt;Left ventricular ejection fraction did not change with increasing percent of emphysema and airflow obstruction.&lt;br&gt;
&lt;br&gt;&quot;Previously, it has been well known that in very severe lung disease, the damage to the lungs affects heart function,&quot; lead author R. Graham Barr, MD, of Columbia University in New York, said in an interview.&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&quot;What we have shown is that a similar physiology, a similar relationship, would appear to extend up and down the spectrum of lung disease from mild, subclinical COPD and emphysema, all the way to moderately severe lung disease.&quot;&lt;/p&gt;
&lt;p&gt;Severe COPD can lead to cor pulmonale, characterized by increased vascular resistance and right heart failure, accompanied by reduced left ventricular filling, left ventricular stroke volume, and cardiac output.&lt;/p&gt;
&lt;p&gt;However, left ventricular ejection fraction (LVEF) usually is preserved. Whether similar changes occurred with less severe COPD had not been determined, and examining that question was the principal objective of the study by Barr and colleagues.&lt;/p&gt;
&lt;p&gt;The study population comprised a subgroup of patients enrolled in the Multi-Ethnic Study of Atherosclerosis (MESA), which is exploring the prevalence, correlates, and progression of subclinical cardiovascular disease. The MESA Lung Study comprised 2,816 MESA participants who underwent cardiac MRI assessment of left ventricular structure and function.&lt;/p&gt;
&lt;p&gt;Investigators in the lung study excluded patients who had a restrictive pattern on spirometry, defined as a forced vital capacity (FVC) below the lower limit of normal and an FEV&lt;sub&gt;1&lt;/sub&gt;:FVC ratio &amp;gt;0.7.&lt;/p&gt;
&lt;p&gt;Information collected for the lung study included patient demographics, smoking history, medical history, level of physical activity, height, weight, resting blood pressure, serum glucose, C-reactive protein, and fibrinogen levels.&lt;/p&gt;
&lt;p&gt;Extent of emphysema was calculated from lung fields of cardiac CT scans, which included 70% of the lung volume from the carina to the base. Investigators defined extent of emphysema as the percentage of voxels below -910 Hounsfield units in the lung windows of cardiac CT scans.&lt;/p&gt;
&lt;p&gt;Participants who smoked at least one cigarette in the 30 days before CT or who had urinary cotinine levels &amp;gt;100 ng/mL were classified as current smokers.&lt;/p&gt;
&lt;p&gt;The mean age of the lung population was 61, and 51% were women. Current smokers accounted for 13% of the participants, former smokers for 38%, and nonsmokers for 49%. LVEF averaged about 70%.&lt;/p&gt;
&lt;p&gt;Mean spirometric measures were normal, as were measures of left ventricular structure and function. Median percent emphysema was 15%. Comparison of percent emphysema with left ventricular measures showed that a 10-point increase in percent emphysema was associated with a: &lt;ul&gt; &lt;li&gt;4.1 mL decrement in LVEDV&lt;/li&gt; &lt;li&gt;2.7 mL decrement in stroke volume&lt;/li&gt; &lt;li&gt;0.19 L/min decrement in cardiac output&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The investigators observed no evidence of an association between percent emphysema and LVEF, reflected in a 0.02-point mean increase with each 10-point increase in extent of emphysema.&lt;/p&gt;
&lt;p&gt;Smoking status significantly influenced associations of percent emphysema with LVEDV (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001 for interaction) and stroke volume (&lt;em&gt;P&lt;/em&gt;=0.008 for interaction).&lt;/p&gt;
&lt;p&gt;The magnitude of the association was greater among smokers than former smokers, and greater among former smokers than nonsmokers. However, the associations were evident in smokers and nonsmokers alike.&lt;/p&gt;
&lt;p&gt;&quot;The apparent effect of emphysema on left ventricular end-diastolic volume and cardiac output was similar to that of traditional cardiac risk factors previously reported in MESA and, among smokers, was greater than that of traditional cardiac risk factors,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;The linearity of associations across the study population &quot;suggests that even early-stage COPD influences stroke volume and left ventricular size,&quot; Anton Vonk-Noordegraaf, MD, of Vrije University Medical Center in Amsterdam, wrote in an accompanying editorial.&lt;/p&gt;
&lt;p&gt;&quot;Since oxygen delivery is directly related to cardiac output, a lower cardiac output in patients with COPD leads to impaired oxygen delivery,&quot; Vonk-Noordegraaf continued.&lt;/p&gt;
&lt;p&gt;&quot;Although the effects on cardiac output were small in this study population, they may be more pronounced in severe cases of emphysema and during exercise, as has been shown previously. The question is whether the striking clinical resemblance between COPD and chronic heart failure can be explained in part by a factor both diseases have in common: decreased cardiac output.&quot;&lt;/p&gt;

                     score="-0"
                     href="http://www.medpagetoday.com/Cardiology/Prevention/tb/18075?impressionId=1265729836845"
                     
      &lt;p&gt;Cutting daily salt intake by 3 grams a day  --  about 30% of the current average  --  could prevent 32,000 strokes and 54,000 myocardial infarctions a year, if a computer model developed by researchers at the University of California, San Francisco accurately depicts the clinical impact of salt reduction.&lt;/p&gt;
&lt;p&gt;The results of the analysis, which used a computer simulation of heart disease in U.S. adults ages 35 to 84, also suggest that even a 1 gram per day reduction in salt over the next decade would be a more cost-effective strategy for treating hypertension than use of even the cheapest antihypertensive, wrote Kirsten Bibbins-Domingo, MD, PhD, and colleagues in a paper published online by the &lt;em&gt;New England Journal of Medicine.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;Lee Goldman, MD, MPH, of Columbia University, who co-authored the paper, told &lt;em&gt;MedPage Today&lt;/em&gt; that their study builds on what has long been known about the adverse health effects of salt on a society that believes it to be the spice of life.&lt;/p&gt;
&lt;p&gt;For example, Goldman said that most people seeking a healthy choice will check food labels and restaurant menus for calorie counts and trans fats, but will not pay attention to salt.&lt;/p&gt;
&lt;p&gt;This is not the first time a call for salt reduction has been issued. As recently as last November, a meta-analysis published in &lt;em&gt;BMJ &lt;/em&gt;suggested that cutting salt intake in half  --  a reduction of about 5 grams a day or roughly a teaspoonful  --  would lower the stroke rate by 23% and reduce overall cardiovascular disease by as much as 17%.&lt;/p&gt;
&lt;p&gt;Americans, like those in many Western countries, take in an average of about 10 g of salt a day; whereas the World Health Organization recommends only 5 g per day, and the U.S. Department of Agriculture recommends daily intake be limited to 5.8 g.&lt;/p&gt;
&lt;p&gt;Bibbins-Domingo and colleagues reported that a 3 gram per day reduction in dietary salt would &quot;save 194,00 to 392,00 quality-adjusted life-years and $10 billion to $24 billion in healthcare costs annually.&quot;&lt;/p&gt;
&lt;p&gt;In an editorial that accompanied the study, Lawrence J. Appel, MD, MPH, and Cheryl A.M. Anderson, PhD, MPH, of Johns Hopkins University, wrote that &quot;the evidence supporting the call to reduce salt intake as a means of preventing cardiovascular disease is compelling.&quot;&lt;/p&gt;
&lt;p&gt;They concluded with this admonition: &quot;As we deliberate healthcare reform, let us not neglect this inexpensive, yet highly effective public health intervention for the prevention of disease.&quot;&lt;/p&gt;
&lt;p&gt;It should be noted that Appel was also first author on a position paper from the American Society of Hypertension that also called for salt reduction as public policy.&lt;/p&gt;
&lt;p&gt;Franz H. Messerli, MD, director of the hypertension program at St. Luke&apos;s-Roosevelt Hospital and a colleague of Goldman&apos;s, said the computer model used in the study was impressive but probably underestimates the benefit of reducing dietary salt &quot;because salt reduction has been shown to have a direct (blood pressure independent) effect on the heart, the brain, the kidneys, and also reduces stomach cancer and osteoporosis  --  factors that were not considered in this analysis.&quot;&lt;/p&gt;
&lt;p&gt;But Messerli found it difficult to lead the victory parade, noting &quot;this is a modeling study and statements such as &apos;A modest reduction of 1 gm per day would be more cost-effective than using medication to lower blood pressure in all persons with hypertension&apos; are to be taken with a good grain of salt.&quot;&lt;/p&gt;
&lt;p&gt;Messerli&apos;s measured response was not echoed by his colleagues in the hypertension world.&lt;/p&gt;
&lt;p&gt;For example, Henry Black, MD, president of the American Society of Hypertension, and director of hypertension research at the New York University School of Medicine said that, although the paper extended the findings of many other studies, it is &quot;more comprehensive and is especially useful by comparing the benefits of [sodium] and [salt] reduction to those of other widely accepted public health approaches that the public and governmental bodies have embraced, including drug treatment.&quot;&lt;/p&gt;
&lt;p&gt;Clyde Yancy, MD, president of the American Heart Association, said that while the study was a computer modeling analysis that may be as good as it gets because &quot;it would be impossible to do a randomized trial in large numbers of high versus low sodium consumption, and the use of modeling with reasonable assumptions represents a solid if not ideal alternative.&quot;&lt;/p&gt;
&lt;p&gt;Moreover, Yancy argued that &quot;the costs and effort involved in setting and/or changing policy&quot; require strong imperatives, and he thought the data reported today &quot;provide that imperative.&quot;&lt;/p&gt;
&lt;p&gt;Three grams of salt comes to about a teaspoonful, but Goldman said it was foolish to think of sodium reduction in terms of such measurements because so much sodium comes from processed foods and from restaurant food. Achieving the needed reduction requires a concerted national effort.&lt;/p&gt;
&lt;p&gt;Bibbins-Domingo noted that their study was limited &quot;by any uncertainty concerning the data entered into the model.&quot;&lt;/p&gt;
&lt;p&gt;Also they noted that they did not &quot;account fully for the possible effects of salt reduction that are unrelated to control of blood pressure  --  for example, potential improvements in outcomes for the increasing numbers of patients with heart failure or prevention of other serious conditions, such as end-stage renal disease.&quot;&lt;/p&gt;

      &lt;p&gt;Lipid control is more than a simple matter of &quot;knowing your numbers,&quot; according to a computer model that found tailoring statin therapy to fit an individual&apos;s five-year risk of heart attack or stroke is a better prevention strategy than treating to preset goals.&lt;/p&gt;
&lt;p&gt;In the model, patients who whose five-year coronary artery disease risk was 5% to 15% received 40 mg of simvastatin (Zocor), while those whose risk was greater were given 40 mg of atorvastatin (Lipitor).&lt;/p&gt;
&lt;p&gt;In every scenario, the tailored approach was preferable, Rodney A. Hayward, MD, of the University of Michigan and the Veterans Affairs Ann Arbor Healthcare System, and colleagues wrote in the Jan. 19 &lt;em&gt;Annals of Internal Medicine.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;While treating-to-target is appealingly simple, that simplicity may be its main limitation, the researchers argued.&lt;/p&gt;
&lt;p&gt;Treating to a single target means that one risk factor receives &quot;dramatically more weight than all other predictors of treatment benefit, resulting in other highly relevant information being either ignored or underweighted,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;That approach, tailoring treatment to reflect multiple risk factors rather than treating-to-target, is an &quot;interesting&quot; one, according to Christopher Cannon, MD, of Brigham and Women&apos;s Hospital in Boston, who was not involved in the study.&lt;/p&gt;
&lt;p&gt;But Cannon, principal investigator of a number of statin trials, said the idea may be a little too late to impact clinical practice.&lt;/p&gt;
&lt;p&gt;&quot;The guidelines won&apos;t shift to this approach any time soon, and in two years, atorvastatin will be generic, so all patients can inexpensively be treated with more intensive therapy (which is better for everyone at all risk levels),&quot; Cannon wrote in an e-mail.&lt;/p&gt;
&lt;p&gt;Although intensive therapy may be better as a rule, he conceded, it&apos;s less cost-effective when an expensive drug is used. When atorvastatin becomes available as a generic, he wrote, for &quot;$4 a month at Walmart it is simply cheaper  --  and of course better  --  to treat everyone with atorvastatin 80 mg.&quot;&lt;/p&gt;
&lt;p&gt;Assuming a population of Americans ages 30 to 75 with no history of myocardial infarction, the authors developed three treatment models: &lt;ul&gt; &lt;li&gt;Standard National Cholesterol Education Program III (NCEP) treat-to-target recommendation, which requires treatment to an LDL target of less than 190 mg/dL for low-risk individuals, less than 160 mg/dL for moderate-risk, and less than 130 mg/dL for high-risk individuals&lt;/li&gt; &lt;li&gt;Intensive NCEP III treat-to-target approach, with targets of less than 100 mg/dL for high-risk individuals&lt;/li&gt; &lt;li&gt;The tailored model, with 40 mg of simvastatin for patients who whose five-year coronary artery disease risk was 5% to 15% and 40 mg of atorvastatin (Lipitor) for higher-risk patients&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;(In both NCEP III strategies statins would be used in a stepwise fashion  --  20 mg simvastatin, 40 mg simvastatin, 40 mg atorvastatin, and, finally, 80 mg atorvastatin  --  to achieve targets).&lt;/p&gt;
&lt;p&gt;Using standard NCEP III treat-to-target recommendations, &quot;37.9 million U.S. persons should receive statins, of which 7.9 million should receive high dose-potency therapy (atorvastatin 40 to 80 mg),&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;Compared with no treatment, the standard strategy would save an estimated 48 quality adjusted life years (QALYs) per 1,000 Americans treated for five years, or a total of 1.83 million total QALYs.&lt;/p&gt;
&lt;p&gt;The intensive NCEP III treat-to-target recommendations would &quot;recommend that 53.4 million U.S. persons receive statins&quot; and would save about 570,000 more QALYs than the standard treatment.&lt;/p&gt;
&lt;p&gt;Using the computer model, this strategy prevented &quot;about 720,000 more nonfatal CAD events and 30,000 more deaths&quot; than the standard treatment.&lt;/p&gt;
&lt;p&gt;Tailored treatment, by contrast, would require that about the same number of people receive a statin  --  53 million. But only 13.3 million would require high-dose statin therapy, versus roughly 18 million who would be given high-dose statin therapy using the intensive NCEP III strategy.&lt;/p&gt;
&lt;p&gt;Even so, the tailored approach would save 520,000 more QALYs than the intensive treatment approach, the authors found.&lt;/p&gt;
&lt;p&gt;&quot;The tailored treatment approach was superior to both NCEP III approaches, resulting in both more CAD morbidity and mortality prevented in the overall population and higher treatment efficiency (greater benefit per person treated),&quot; they wrote.&lt;/p&gt;
&lt;p&gt;The authors noted a number of limitations, including the paucity of clinical trial data on statin therapy in persons ages 75 or older.&lt;/p&gt;
&lt;p&gt;Moreover, although the model suggested a robust benefit for tailored treatment, &quot;the absolute population-level benefit of the tailored treatment over the treat-to-target approaches are much less certain and can vary substantially on the basis of several factors, such as statin&apos;s effect on total mortality (estimates of which are less precise in the literature than estimates for nonfatal CAD events) and the level of treatment adherence that is achievable in real-world clinical practice.&lt;/p&gt;
&lt;p&gt;&quot;Whether a tailored treatment approach is superior for other conditions in which treat-to-target strategies are currently recommended, such as blood pressure and glycemic control, warrants examination,&quot; they concluded.&lt;/p&gt;
