                     score="0.015"

      &lt;p&gt;Using sirolimus-eluting stents for the treatment of in-stent restenosis appears safe and effective over four years of follow-up, a study of an Italian registry showed.&lt;/p&gt;
&lt;p&gt;Through four years, there were low rates of target lesion revascularization (11.1%) and stent thrombosis (2.8%), according to Francesco Liistro, MD, of San Donato Hospital in Arezzo, Italy, and colleagues.&lt;/p&gt;
&lt;p&gt;About one in 10 patients (9.8%) died, and 3.2% had a nonfatal myocardial infarction.&lt;/p&gt;
&lt;p&gt;Survival free from a major adverse cardiac event was 80.3% at the end of follow-up, the researchers reported in the Feb. 16 issue of the&lt;em&gt; Journal of the American College of Cardiology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Although drug-eluting stents have been shown to be safe and better than balloon angioplasty and vascular brachytherapy for in-stent restenosis in the short term, most previous studies have had limited follow-up.&lt;/p&gt;
&lt;p&gt;Reports of late stent thrombosis following implantation with drug-eluting stents have raised some concern about the long-term safety of these devices in unselected patient groups, according to Liistro and his colleagues.&lt;/p&gt;
&lt;p&gt;To explore the issue, the researchers turned to the Tuscany Registry of Unselected In-Stent Restenosis (TRUE), a prospective, two-center registry.&lt;/p&gt;
&lt;p&gt;All 244 patients included in the analysis underwent antiplatelet therapy with aspirin and either ticlopidine or clopidogrel (Plavix) for at least six months after the sirolimus-eluting stent was implanted.&lt;/p&gt;
&lt;p&gt;An earlier, nine-month analysis of this registry showed safety and effectiveness for the stent. This study confirmed the benefits through four years.&lt;/p&gt;
&lt;p&gt;Of 24 recorded deaths, 11 were from cardiac causes.&lt;/p&gt;
&lt;p&gt;Definite stent thrombosis occurred in five patients, four of whom had stopped taking clopidogrel more than a month before the event.&lt;/p&gt;
&lt;p&gt;Another two patients who were taking aspirin and clopidogrel had probable stent thrombosis.&lt;/p&gt;
&lt;p&gt;Patients who had diabetes were significantly more likely to have target lesion revascularization (OR 0.32, 95% CI 0.14 to 0.71) and major adverse cardiac events (OR 0.38, 95% CI 0.20 to 0.71) through four years.&lt;/p&gt;
&lt;p&gt;A left ventricular ejection fraction less than 50% was associated with higher odds of major adverse cardiac events (OR 0.32, 95% CI 0.13 to 0.80), as was creatinine greater than 1.5 mg/dL (OR 0.23, 95% CI 0.11 to 0.48).&lt;/p&gt;
&lt;p&gt;And patients with peripheral or carotid arterial disease were more likely to need target lesion revascularization (OR 0.35, 95% CI 0.14 to 0.88).&lt;/p&gt;
&lt;p&gt;The authors noted that the registry study was limited by the lack of valid control groups.&lt;/p&gt;
&lt;p&gt;In addition, in patients with a late occurrence of target lesion revascularization, the researchers could not determine whether a stenotic lesion inside the stented segment was a new atherosclerotic lesion or a restenosis.&lt;/p&gt;

                     score="0.015"
                     href="http://www.medpagetoday.com/Cardiology/AcuteCoronarySyndrome/tb/18387?impressionId=1265806680364"
                     
      &lt;p&gt;Contrary to guidelines, the absence of coronary artery calcium doesn&apos;t rule out coronary artery disease in symptomatic patients, researchers found in a new study.&lt;/p&gt;
&lt;p&gt;In a multicenter clinical trial, 19% of patients with a coronary calcium score of 0 had stenosis of at least 50% in one or more coronary artery segments, according to Carlos E. Rochitte, MD, of the University of S&amp;#227;o Paulo, Brazil, and colleagues.&lt;/p&gt;
&lt;p&gt;Likewise, 20% of vessels seen to be totally occluded on revascularization had no calcium on scans, they reported in the Feb. 16 issue of the &lt;em&gt; Journal of the American College of Cardiology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;&quot;The absence of coronary calcification should not be used as a gatekeeper and should not prevent a symptomatic patient from undergoing angiography,&quot; the researchers wrote.&lt;/p&gt;
&lt;p&gt;Currently, American Heart Association/American College of Cardiology guidelines suggest that excluding measurable coronary calcium could serve as an effective filter for sending patients on to invasive testing or admitting them.&lt;/p&gt;
&lt;p&gt;One systematic review of 18 studies had indicated that a zero calcium score had a negative predictive value of 93% for stenosis and a positive predictive value of 68% in symptomatic patients.&lt;/p&gt;
&lt;p&gt;However, in Rochitte&apos;s trial  --  CORE64 (Coronary Evaluation Using Multi-Detector Spiral Computed Tomography Angiography Using 64 Detectors)  --  the negative predictive value of a coronary calcium score of 0 was 68%, while the positive predictive value was 81%.&lt;/p&gt;
&lt;p&gt;Overall sensitivity to predict the absence of significant (at least 50%) stenosis was 45%, while specificity was 91%.&lt;/p&gt;
&lt;p&gt;&quot;This apparent lack of predictive value of a calcium scan should be enough to give a clinician pause,&quot; Rita F. Redberg, MD, of the University of California San Francisco, wrote in an accompanying editorial.&lt;/p&gt;
&lt;p&gt;Whatever the reason for the discrepancy, neither the trial nor the review provided any information on how coronary calcium scans add incrementally to traditional predictors of coronary artery disease, such as clinical assessment and stress testing, she said. Nor would she rule out their use entirely for patients with chest pain.&lt;/p&gt;
&lt;p&gt;&quot;Given the significant &lt;a href=&quot;http://www.medpagetoday.com/Cardiology/AcuteCoronarySyndrome/12732&quot; mce_href=&quot;http://www.medpagetoday.com/Cardiology/AcuteCoronarySyndrome/12732&quot; target=&quot;_blank&quot;&gt;radiation risks&lt;/a&gt; of coronary artery calcium scans, however, clinicians must use extreme caution when ordering such scans,&quot; Redberg cautioned.&lt;/p&gt;
&lt;p&gt;The prospective &lt;a href=&quot;http://www.medpagetoday.com/Radiology/DiagnosticRadiology/11927&quot; mce_href=&quot;http://www.medpagetoday.com/Radiology/DiagnosticRadiology/11927&quot; target=&quot;_blank&quot;&gt;CORE64 study&lt;/a&gt; was originally designed to compare diagnostic performance of CT and invasive angiography in symptomatic patients with suspected coronary artery disease. But it also included a coronary calcium scan up to 30 days prior to conventional angiography.&lt;/p&gt;
&lt;p&gt;Of the 291 patients included in the calcium score analysis (73% male, mean age 59.3), 56% had at least 50% coronary stenosis by conventional angiography and 45% had at least 70% stenosis.&lt;/p&gt;
&lt;p&gt;Calcium score only weakly correlated with the highest degree of coronary stenosis found in a patient. Its ability to predict presence of significant lesions was &quot;moderate&quot; (area under the receiver-operating characteristic curve 0.77, &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;A non-zero score was associated with 8.1-fold likelihood of having at least 50% coronary stenosis (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001) after adjusting for age, sex, hypertension, dyslipidemia, family history of premature heart disease, diabetes, race, and hospitalization.&lt;/p&gt;
&lt;p&gt;Among the 100 patients who went on to revascularization within 30 days of angiography, 13% had a coronary calcium score of 0, 25% had a score of 1 to 10, and 44% had a score over 10 (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001 for trend).&lt;/p&gt;
&lt;p&gt;The fact that significant coronary artery disease occurred in the absence of calcification in almost 20% of patients should not be surprising, since coronary calcification is thought to occur late in the atherosclerotic process, while obstruction can occur earlier, Redberg asserted.&lt;/p&gt;
&lt;p&gt;The researchers also cautioned that the results would not apply to asymptomatic patients with intermediate risk for events, a group in which a score of 0 has been consistently shown to indicate low risk.&lt;/p&gt;

Reynolds Foundation.&lt;/p&gt;&lt;p&gt;Rochitte reported no conflicts of interest. Co-authors reported financial relationships with Toshiba Medical Systems, Bayer, Schering, GE Healthcare, Bracco, Bristol-Myers Squibb, sanofi-aventis, and Vital Images.&lt;/p&gt;&lt;p&gt;Redberg provided no information on conflicts of interest.&lt;/p&gt;&lt;/div&gt;&lt;div style=&quot;clear:both;&quot;&gt;&lt;/div&gt;

                     score="0.01"

      &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;

      &lt;p&gt;Middle-aged patients with early knee osteoarthritis can benefit from either a self-managment program or strength training, but a combination of the two did not provide additional gains, a study found.&lt;/p&gt;
&lt;p&gt;During a two-year trial, roughly two-thirds of participants randomized to one of three groups achieved clinically meaningful improvements in functioning, defined as a 26% change from baseline, according to a new report in the Jan. 15 &lt;em&gt;Arthritis Care &amp;amp; Research&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Patients also achieved clinically meaningful improvements in pain -- defined as a 40% change from baseline -- regardless of treatment group, wrote Patrick E. McKnight, PhD, of George Mason University in Fairfax, Va., and colleagues.&lt;/p&gt;
&lt;p&gt;The functional improvements were 70% for patients in the strength training group, 64% for those in the self-management group, and a 66% improvement in the combined treatment group. For pain, the breakdown was as follows: &lt;ul&gt; &lt;li&gt;Strength training, 65%&lt;/li&gt; &lt;li&gt;Self-management, 56%&lt;/li&gt; &lt;li&gt;Combined treatment, 65%&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;McKnight and colleagues wrote that studies in older patients have reported positive changes for both strength training and self-management.&lt;/p&gt;
&lt;p&gt;To see if these modalities also could benefit younger patients with milder disease, and whether combining the two would lead to additional benefits, the investigators recruited 273 subjects ages 35 to 64 years.&lt;/p&gt;
&lt;p&gt;Participants all had pain on most days in at least one knee, had symptoms for less than five years, had radiographic evidence of osteoarthritis, and had self-reported disability.&lt;/p&gt;
&lt;p&gt;The strength training program consisted of two phases, the first being nine months focused on stretching and balance, range of motion and flexibility, and isotonic muscle strengthening in three sessions each week.&lt;/p&gt;
&lt;p&gt;Phase two involved the development of self-directed long-term exercising habits, following the guidance and advice of trainers.&lt;/p&gt;
&lt;p&gt;The self-management program also included two phases. During the first nine-month phase, participants attended 12 weekly 90-minute classroom sessions addressing coping and self-efficacy skills, promoting active adaptive strategies and increasing perception of control for physical function and pain management.&lt;/p&gt;
&lt;p&gt;Phase two consisted of telephone calls from instructors and problem-solving discussions.&lt;/p&gt;
&lt;p&gt;The combined treatment group concurrently participated in both strength training and self-management programs, adjusted to maintain equivalent contact time with the other two groups.&lt;/p&gt;
&lt;p&gt;Overall compliance was modest, with 55.8% of those in the strength training group completing the study, along with 69.1% and 59.6% of the self-management and combined groups, respectively.&lt;/p&gt;
&lt;p&gt;Objective measures of physical functioning consisted of five physical performance tests measured at baseline and at months nine and 24. Pain and disability were self-reported.&lt;/p&gt;
&lt;p&gt;All of these outcomes showed significant changes over time in all three treatment groups, with effect sizes computed using the standard Cohen&apos;s d units: &lt;ul&gt; &lt;li&gt;Leg press, d=0.85&lt;/li&gt; &lt;li&gt;Range of motion, d=1.00&lt;/li&gt; &lt;li&gt;Work capacity, d=0.60&lt;/li&gt; &lt;li&gt;Balance, d=0.59&lt;/li&gt; &lt;li&gt;Stair climbing, d=0.59&lt;/li&gt; &lt;li&gt;Pain, d= &amp;#8722;0.51&lt;/li&gt; &lt;li&gt;Disability, d= &amp;#8722;0.55&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Both men and women improved, although benefits were greater among men, who gained more large muscle mass strength. Study-related adverse effects included accident, injury, or increased pain with strength training.&lt;/p&gt;
&lt;p&gt;Within-group and between-group effect sizes were also computed. All within-group effect sizes differed significantly from zero, with the exception of the pain outcome in the strength training group, but none of the between-group effects were significant.&lt;/p&gt;
&lt;p&gt;&quot;The logic behind the combined treatment was that the different factors addressed in physical and psychological treatments might produce an additive effect if administered together. These results suggest otherwise,&quot; the investigators conceded.&lt;/p&gt;
&lt;p&gt;As to why there were no differences between the three treatment arms, the length of the study and the relative youth of the participants may have contributed.&lt;/p&gt;
&lt;p&gt;The sample was younger than are included in typical osteoarthritis studies and were higher functioning at baseline, which could mean that there was less opportunity to produce a significant effect, the investigators suggested.&lt;/p&gt;
&lt;p&gt;Also, the increased burden of the combined treatment may have diluted the effects of the two programs.&lt;/p&gt;
&lt;p&gt;Despite the fact that combined treatment in this study had negligible benefits beyond that seen with strength training and self-management, other long-term outcomes such as physical activity level might show a greater response. This remains speculative, but deserves further study, according to the investigators.&lt;/p&gt;
&lt;p&gt;Limitations of the study include the fact that the researchers did not assess effects of the treatment on articular cartilage or inflammation, and they did not include a no-treatment arm.&lt;/p&gt;
&lt;p&gt;Also, there may have been differences in self-medication practices between the groups.&lt;/p&gt;
&lt;p&gt;Nonetheless, the study findings suggest that the two nonpharmacologic approaches can produce gains in middle-age patients with osteoarthritis, and both can be recommended.&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=1265806680364"
                     
      &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;
