      &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="0.009"
                     href="http://www.medpagetoday.com/PublicHealthPolicy/Medicare/tb/18269?impressionId=1265782923827"
                     
      &lt;p&gt;Some genomic tests aimed at identifying patients most likely to respond to cancer drugs won a thumbs-up from a Medicare advisory panel, but others didn&apos;t make the grade.&lt;/p&gt;
&lt;p&gt;As part of a national coverage determination under way at the Centers for Medicare and Medicaid Services, members of the Medicare Evidence Development &amp;amp; Coverage Advisory Committee (MEDCAC) last week rated the clinical value of several pharmacogenomic cancer tests now available.&lt;/p&gt;
&lt;p&gt;The tests would be used to select patients for treatment with drugs including tamoxifen, irinotecan (Camptosar), trastuzumab (Herceptin), and imatinib (Gleevec).&lt;/p&gt;
&lt;p&gt;CMS has not previously decided whether such tests should be reimbursed by Medicare, although testing is already routine for some of these treatments.&lt;/p&gt;
&lt;p&gt;The FDA-approved labeling for trastuzumab requires such testing. Imatinib&apos;s approvals include chronic myeloid leukemia featuring the BCR-ABL &quot;Philadelphia chromosome&quot; mutation, although the label doesn&apos;t explicitly mention testing.&lt;/p&gt;
&lt;p&gt;&quot;CMS is aware that the body of evidence on the role of pharmacogenomic testing in cancer continues to evolve,&quot; according to the agency&apos;s notice of the meeting.&lt;/p&gt;
&lt;p&gt;&quot;Recognizing the rapid accumulation of such evidence, CMS seeks guidance from the panel to inform future coverage determinations. We want to ensure that Medicare beneficiaries have access to any demonstrated improved health outcomes of pharmacogenomic testing, and are protected from inaccurate or inappropriate pharmacogenomic testing that could compromise therapy or increase the risks of adverse events during therapy.&quot;&lt;/p&gt;
&lt;p&gt;MEDCAC panelists were asked to rate their confidence in the clinical utility of five tests and in the scientific evidence available for review.&lt;/p&gt;
&lt;p&gt;The five tests cover: &lt;ul&gt; &lt;li&gt;Polymorphisms in the CYP2D6 drug-metabolizing enzyme for breast cancer patients who are candidates for tamoxifen&lt;/li&gt; &lt;li&gt;Polymorphisms in the UGT1A1 gene for colon cancer patients considered for irinotecan treatment&lt;/li&gt; &lt;li&gt;Presence of HER/neu epidermal growth factor receptor expression in patients with breast cancer, indicating suitability for trastuzumab&lt;/li&gt; &lt;li&gt;Presence of the BCR-ABL mutation in patients with chronic myeloid leukemia who would be candidates for imatinib&lt;/li&gt; &lt;li&gt;Mutations in the K-ras gene for metastatic colorectal cancer patients eligible for cetuximab (Erbitux) or panitumumab (Vectibix)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The 15 panel members assigned values of one to five, reflecting low to high confidence, to each test. A score of two reflected medium-low confidence, while a four meant medium-high confidence.&lt;/p&gt;
&lt;p&gt;Most of the panelists agreed that the evidence underlying the tests for CYP2D6 and UGT1A1 polymorphisms was still too scant for an assessment of their clinical value. Mean scores for these tests were 2.07 and 1.83, respectively, with nearly all votes either a one or two.&lt;/p&gt;
&lt;p&gt;But MEDCAC members were more confident that the usefulness of the other three tests for diagnostic and monitoring purposes could be evaluated. Mean scores for those tests were all well above four.&lt;/p&gt;
&lt;p&gt;For the HER/neu, BCR-ABL, and K-ras tests, since members believed the evidence was adequate for assessment, MEDCAC also voted on whether their use actually would improve health outcomes in cancer patients.&lt;/p&gt;
&lt;p&gt;A third ranking provided the committee&apos;s views on whether the conclusions could be generalized to the Medicare population and patients in the community.&lt;/p&gt;
&lt;p&gt;Mean scores for those rankings were all also above four, indicating the panel&apos;s support for these tests as clinically beneficial.&lt;/p&gt;
&lt;p&gt;On the other hand, when asked whether there was enough evidence to assess the utility of the BCR-ABL test in detecting treatment failure, panelists didn&apos;t think so. Most of those votes were twos, and the mean was 2.47.&lt;/p&gt;
&lt;p&gt;CMS has not given a time line for deciding whether to approve Medicare coverage for the tests.&lt;/p&gt;

                     title="ADT for Prostate Cancer Raises Heart Risks"
                     score="0.009"
                     href="http://www.medpagetoday.com/Urology/ProstateCancer/tb/18250?impressionId=1265782923827"
                     
      &lt;p&gt;Androgen deprivation therapy (ADT) for prostate cancer can exacerbate cardiac risk factors and may increase the risk of heart attack and cardiac death, according to an advisory supported by four medical organizations.&lt;/p&gt;
&lt;p&gt;However, the groups did not offer specific guidelines for clinicians on when to employ ADT therapy or avoid it.&lt;/p&gt;
&lt;p&gt;Clinical trials have shown that ADT increases body weight, decreases lean mass and increases fat mass, reduces insulin sensitivity, and triggers or worsens dyslipidemia.&lt;/p&gt;
&lt;p&gt;Several studies have demonstrated a significant increase in cardiovascular death in prostate cancer patients treated with hormonal therapy or bilateral orchiectomy, although some studies have shown no association between ADT and increased cardiovascular risk, according to a report that will appear in the Feb. 16 issue of &lt;em&gt;Circulation: Journal of the American Heart Association&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Some evidence also suggests ADT may predispose men to metabolic syndrome.&lt;/p&gt;
&lt;p&gt;&quot;Based on current data, it was appropriate to conclude that there may be a relationship between ADT therapy in patients with prostate cancer and future cardiovascular risk,&quot; Glenn N. Levine, MD, of Baylor College of Medicine in Houston and chair of the advisory writing committee, said in a statement.&lt;/p&gt;
&lt;p&gt;The writing committee comprised representatives of the American Heart Association, American Urological Association, and American Cancer Society. Additionally, the American Society for Radiation Oncology endorsed the advisory.&lt;/p&gt;
&lt;p&gt;The authors&apos; review of literature showed that ADT increased cardiovascular risk in 1% to 6% of various studies&apos; patient populations. With that in mind, &quot;the decision about whether to initiate ADT should be based on weighing the benefits of therapy with this potential modest risk,&quot; Levine said.&lt;/p&gt;
&lt;p&gt;The decision to initiate ADT should remain with the physician who has responsibility for treating a patient with prostate cancer, the authors wrote. That includes patients with known cardiac disease.&lt;/p&gt;
&lt;p&gt;&quot;It is the consensus of the writing group that there is no clear indication for patients for whom ADT is believed to be beneficial to be referred to internists, endocrinologists, or cardiologists for evaluation before initiation of ADT,&quot; the authors said.&lt;/p&gt;
&lt;p&gt;&quot;The decision as to whether or not to initiate ADT in patients with cardiac disease, in whom the benefits of therapy would be weighed against any possible risks, is most appropriately made by the physician treating the patient for prostate cancer.&quot;&lt;/p&gt;
&lt;p&gt;However, the potential adverse metabolic effects warrant periodic evaluation by a patient&apos;s primary care physician, they added.&lt;/p&gt;
&lt;p&gt;Noting a lack of clinical guidance for follow-up of patients treated with ADT, the advisory authors concluded that at least an annual assessment of blood glucose and lipids seems reasonable. They also called for prospective assessment of cardiovascular risk factors before and after ADT is begun in future clinical trials.&lt;/p&gt;

                     score="0.004"
                     href="http://www.medpagetoday.com/Cardiology/CHF/tb/18193?impressionId=1265782923827"
                     
      &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="0.003"
                     href="http://www.medpagetoday.com/HematologyOncology/ColonCancer/tb/18164?impressionId=1265782923827"
                     
      Patients 65 and older are as suitable as younger individuals for CT colonography, said researchers conducting a large retrospective study.&lt;br&gt;
&lt;br&gt;Advanced neoplasias were detected with CT colonography  --  often called &quot;virtual colonoscopy&quot;  --  in older patients at more than double the rate in the general screening population, reported David H. Kim, MD, of the University of Wisconsin in Madison, Wis., and colleagues in the February issue of &lt;em&gt;Radiology&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;They found that 7.6% of older patients had advanced neoplasias, compared with 3.2% of all patients screened in the university&apos;s clinic (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;On the basis of this and other findings in 577 individuals 65 and older versus the entire group of 3,120 patients undergoing the procedure, Kim and colleagues concluded that &quot;CT colonography performance is maintained in an older cohort.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Overall, the observations from this clinical experience confirm that CT colonography may be a valuable screening modality in the older population,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;On the other hand, the study did not address several objections raised by the Centers for Medicare and Medicaid Services (CMS) in its decision last year to deny Medicare coverage for the procedure. (See &lt;a href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/Medicare/14186&quot; mce_href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/Medicare/14186&quot; target=&quot;_blank&quot;&gt;Medicare Finalizes Denial of Virtual Colonoscopy Coverage&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;CMS had pointed to relatively low sensitivity of CT colonography compared with optical colonoscopy in prospective trials, especially for small lesions.&lt;/p&gt;
&lt;p&gt;The agency also determined that CT colonography increased the costs of positive findings, since abnormalities in the CT scans must be confirmed with optical colonoscopy. In addition, CMS said there was no evidence to support claims that the less invasive imaging procedure would be more acceptable to patients and therefore would raise screening rates.&lt;/p&gt;
&lt;p&gt;The data analyzed by Kim and colleagues did not allow for calculations of false-negative rates or predictive values of positive or negative findings. Nor did the researchers report cost information.&lt;/p&gt;
&lt;p&gt;Mean age of their older cohort was 69.2 (SD 3.8). The oldest was 79.&lt;/p&gt;
&lt;p&gt;The researchers reported that 15.3% of the older patients were referred for optical colonoscopy on the basis of the CT results, compared with 7.9% of the overall screening group.&lt;/p&gt;
&lt;p&gt;Less than 4% of positive findings were determined to be false with the optical procedure (3.6% for polyps 6 to 10 mm in diameter, 2.1% for larger lesions).&lt;/p&gt;
&lt;p&gt;Of the 59 advanced neoplasias identified in the older patients, all but three were at least 10 mm in size.&lt;/p&gt;
&lt;p&gt;The scans also suggested abnormalities outside the colon in 89 (15.4%) patients. Of these, 45 received a full workup, which revealed substantial and previously unsuspected diagnoses in 21 cases  -- 18 were vascular aneurysms. The other three included one lung tumor, a femoral hernia, and a malrotation.&lt;/p&gt;
&lt;p&gt;Kim and colleagues reported that no &quot;substantial complications&quot; such as perforations or major hemorrhage occurred in the older patients, either with the CT scan or follow-up colonoscopy.&lt;/p&gt;
&lt;p&gt;They also indicated that the ratio of large to small neoplasias was similar in the older patients compared with their CT screening group as a whole. Histologic and morphologic findings were similar as well.&lt;/p&gt;
&lt;p&gt;The researchers cited the observational nature of the study, in which negative findings were not corroborated with optical colonoscopy, and its restriction to a single center as its main limitations.&lt;/p&gt;
