      The physical and verbal abuse nurses face on the job often goes unreported, according to an Australian survey.&lt;br&gt;
&lt;br&gt;Over the prior year, 52% of nurses in one community hospital said they had been physically assaulted and 69% reported being threatened with violence, according to Rose Chapman, PhD, of the University of Western Australia in Perth, and colleagues.&lt;br&gt;
&lt;br&gt;Verbal abuse was almost universal, being reported by 92% of respondents, the researchers wrote in the February issue of the &lt;em&gt;Journal of Clinical Nursing&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;However, only half mentioned the incidents to senior staff or co-workers, and just 16% filed an official report.&lt;br&gt;
&lt;br&gt;&quot;The reasons for not reporting are many and may include lack of time and management support and the belief that being attacked is &apos;just part of the job,&apos;&quot; they wrote.&lt;br&gt;
&lt;br&gt;The same is true in the U.S., where assaults and under-reporting appear just as common as suggested in the Australian survey, commented Kathleen M. McPhaul, PhD, RN, MPH, of the University of Maryland School of Nursing in Baltimore, who has been involved in such research in the U.S.&lt;br&gt;
&lt;br&gt;A culture change would likely be needed to make a real difference for nurses, Chapman&apos;s group suggested.&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Hospitals would have to ensure that nurses have necessary support, education, encouragement, and time to complete official reports. Nurses who report abuse should get positive feedback from all levels of nursing, they said.&lt;/p&gt;
&lt;p&gt;&quot;If administrators and governments are serious in their intention to reduce workplace violence and provide staff with safe work environments, they should be seen to act on all reported [incidents],&quot; which is rare today, Chapman&apos;s group wrote.&lt;/p&gt;
&lt;p&gt;However, currently there&apos;s no strong lever or incentive to address this kind of workplace abuse since hospitals focus mainly on patient safety as part of accreditation, and national and state workplace safety organizations have little mechanism for monitoring such incidents, McPhaul noted.&lt;/p&gt;
&lt;p&gt;The researchers&apos; survey was intended to reach all 332 nurses working at one nontertiary hospital across all departments  --  emergency, medical, surgical, maternity, pediatric, and mental health.&lt;/p&gt;
&lt;p&gt;The 113 nurses who responded were mainly women in their early 40s who worked part time.&lt;/p&gt;
&lt;p&gt;Among them, about three-quarters reported at least one incident of workplace violence over the preceding 12 months  --  25% said it occurred weekly, 27% said monthly, and for 25% it was rarer, at once every six months. &lt;ul&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Fully 30% of the nurses said they had been involved in an episode involving a weapon  --  often hospital equipment and more rarely a knife or gun.&lt;/p&gt;
&lt;p&gt;The number of total incidents was lowest among nurse midwives, with a mean of 1.67 per year.&lt;/p&gt;
&lt;p&gt;Not surprisingly, the rate was highest among emergency department and mental health staff, who reported an average of 46.43 and 40.39 episodes over 12 months.&lt;/p&gt;
&lt;p&gt;One reason behind the high risk in these two departments may be the &quot;shift to a community-based approach to mental health care and a reduction in mental health beds&quot; such that the same psychiatric patients that assault mental health department nurses are mainstreamed to the emergency department as their point of entry to the hospital, the researchers said.&lt;/p&gt;
&lt;p&gt;However, more years of experience or higher educational qualification didn&apos;t appear to protect nurses. Senior nurse unit managers and clinical nurse specialists actually reported more physical assaults than less senior nurses.&lt;/p&gt;
&lt;p&gt;Age and gender didn&apos;t predict occurrence or type of incident either.&lt;/p&gt;
&lt;p&gt;When nurses did report workplace violence or verbal abuse, it was most often to their immediate manager (29%), other senior nursing staff (14.5%), or to their friends and colleagues (6%).&lt;/p&gt;
&lt;p&gt;Overall, 30% of nurses who responded to the survey gave as their reason for not reporting that workplace violence happens all the time and is simply part of the job.&lt;/p&gt;
&lt;p&gt;Even among those who did make a report of some sort, half said they thought hospital management failed to act on it.&lt;/p&gt;
&lt;p&gt;In fact, when the researchers audited hospital records, they found that 42 official incident reports had been filed by nurses over the prior one year period, nearly always involving injuries.&lt;/p&gt;
&lt;p&gt;In 95% of the cases, the only action taken by the hospital was making staff in the area aware of the incident. No other actions had been documented.&lt;/p&gt;
&lt;p&gt;The researchers cautioned that the voluntary nature and limited scope of the study may have limited generalizability, although the occurrence of violence against nurses is likely similar across developed countries.&lt;/p&gt;

                     href="http://www.medpagetoday.com/Cardiology/AcuteCoronarySyndrome/tb/18279?impressionId=1265771690020"
                     
      &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/PCI/tb/18226?impressionId=1265771690020"
                     
      &lt;p&gt;No evidence of a platelet aggregation rebound occurs with abrupt discontinuation of clopidogrel (Plavix) in patients undergoing percutaneous coronary intervention (PCI), investigators in a randomized clinical trial concluded.&lt;/p&gt;
&lt;p&gt;Values for adenosine diphosphate (ADP)-induced platelet aggregation did not differ significantly between patients whose clopidogrel therapy was withdrawn abruptly and those in whom clopidogrel was tapered before discontinuation, they wrote in an article in the Feb. 9 issue of the &lt;em&gt;Journal of the American College of Cardiology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;The findings also showed that tapering of clopidogrel does not lead to lower platelet aggregation values after clopidogrel withdrawal, according to Dirk Sibbing, MD, of Technical University Munich in Germany, and colleagues&lt;em&gt;&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;&quot;The time course of platelet aggregation values  --  regardless of the device, the agonist, or the agonist concentration used  --  after clopidogrel cessation provides no evidence for the existence of a rebound phenomenon of platelets after discontinuing clopidogrel,&quot; they wrote in conclusion.&lt;/p&gt;
&lt;p&gt;For patients undergoing PCI, dual antiplatelet therapy with aspirin and clopidogrel has become the mainstay for prevention of thrombotic events. Lifelong aspirin therapy is recommended for patients after PCI, but clinical guidelines recommend discontinuation of clopidogrel after six or 12 months. The standard practice is to withdraw clopidogrel abruptly, the authors noted.&lt;/p&gt;
&lt;p&gt;Recent studies have shown a clustering of thrombotic events in the first few weeks after discontinuation of long-term clopidogrel therapy. The observations have led to the hypothesis of a rebound phenomenon of platelet aggregation. However, the hypothesis had not been examined specifically within the context of clopidogrel withdrawal.&lt;/p&gt;
&lt;p&gt;&quot;Because different studies have demonstrated that insufficient suppression of platelet reactivity to ADP is associated with an increased risk of thrombotic events after coronary stent placement, the observed clustering of adverse events reported in clinical studies might be related to an intermittent status of platelet hyperreactivity or so-called platelet rebound with very high ADP-induced platelet aggregation levels,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;&quot;A tapering of clopidogrel treatment over a certain period of time before stopping the intake of the drug completely might provide a beneficial treatment strategy to attenuate this supposed rebound phenomenon of platelets.&quot;&lt;/p&gt;
&lt;p&gt;Sibbing and colleagues designed a randomized clinical trial to determine whether a rebound phenomenon exists after discontinuation of clopidogrel and whether the rebound can be attenuated by a clopidogrel-tapering regimen.&lt;/p&gt;
&lt;p&gt;The investigators enrolled 69 patients receiving clopidogrel in association with PCI procedures. In all cases, discontinuation of clopidogrel was planned.&lt;/p&gt;
&lt;p&gt;The patients were randomized to two strategies of discontinuation: tapering of the clopidogrel dose over four weeks, followed by discontinuation; or treatment for four weeks, as planned, followed by abrupt discontinuation.&lt;/p&gt;
&lt;p&gt;Investigators assessed platelet aggregation at enrollment and during weeks two through eight after randomization. Aggregation was assessed simultaneously by light transmission aggregometry (LTA) and multiple electrode aggregometry (MEA).&lt;/p&gt;
&lt;p&gt;The primary endpoint was the highest rate of ADP-induced platelet aggregation by LTA in weeks five through eight after clopidogrel withdrawal.&lt;/p&gt;
&lt;p&gt;Platelet aggregation by LTA peaked at 73% in the group that had clopidogrel abruptly withdrawn and at 69.3% in the tapering group, resulting in a nonsignificant difference (&lt;em&gt;P&lt;/em&gt;=0.21). The between-group values did not differ across the range of ADP concentrations used (1.25 to 20 &amp;#181;mol/L).&lt;/p&gt;
&lt;p&gt;Results by MEA were similar: The peak aggregation value associated with abrupt withdrawal was 925 AU x min compared with 890 AU x min with clopidogrel tapering (&lt;em&gt;P&lt;/em&gt;=0.55).&lt;/p&gt;
&lt;p&gt;Studies with different agonists of platelet aggregation also yielded similar results in the two patient groups.&lt;/p&gt;
&lt;p&gt;Despite finding no difference between the two strategies for clopidogrel withdrawal, the authors did not rule out the possibility of a beneficial effect of tapering clopidogrel.&lt;/p&gt;
&lt;p&gt;&quot;It could be hypothesized that, apart from the maximal values of platelet aggregation observed, a more gradual increase of platelet aggregation values achieved by a clopidogrel-tapering regimen is beneficial for the reduction of thrombotic events,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;&quot;In fact, we observed a relatively rapid increase of platelet aggregation values in the [abrupt withdrawal] group of patients in our study. Whether this rapid increase might be disadvantageous in case of stopping clopidogrel treatment remains uncertain.&quot;&lt;/p&gt;

                     title="Peptide Predicts Heart Failure in Older Patients (CME/CE)"
                     score="0.006"
                     href="http://www.medpagetoday.com/Cardiology/CHF/tb/18193?impressionId=1265771690020"
                     
      &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;

                     title="Benefits of Cutting Down on Salt Quantified (CME/CE)"
                     score="-0.001"
                     href="http://www.medpagetoday.com/Cardiology/Prevention/tb/18075?impressionId=1265771690020"
                     
      &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;
