Marathon Runners Have Low Risk of Cardiac ArrestA study of over 10 million runners of marathons and half-marathons has found that participating in these events is associated with a low risk of cardiac arrest compared with other athletic activities.

Impaired insulin sensitivity in patients with stable chronic heart failureWe showed that impaired insulin sensitivity in patients with chronic heart failure (CHF) significantly predicted impaired survival. Insulin resistance relates to an advanced disease state and higher mortality independent of body composition and established prognosticators, implicating a pathophysiologic role for insulin sensitivity in CHF. Patients with CHF may possibly benefit from early treatment of impaired insulin sensitivity, but further research is needed.

Perlara, Harvard, Undiagnosed Diseases Network to Research Neurodevelopmental DisordersThe drug discovery platform company, Perlara, has joined forces with Harvard Medical School and the Undiagnosed Diseases Network to launch PerlQuests for two rare neurodevelopmental disorders, Coffin-Lowry syndrome, caused by a mutation in the RPS6KA3 gene, and GNAO1 encephalopathy.

Why Is the EHR Market So Anemic?High costs, unreliable vendors, lengthy installation and transition processes, disruptions to workflow, reduced productivity--it's no wonder that so few practices have adopted full-featured EHRs.

Medication nonadherence and adverse outcomes in CAD patientsNonadherence to beta blockers, statins, or angiotensin-converting enzyme inhibitors is common (21%-29%) among patients with coronary artery disease (CAD). Patients who do not adhere to their medication regimens are at increased risk of mortality, cardiovascular hospitalizations, and revascularization procedures; thus, medication nonadherence should be a target for quality improvement interventions to maximize the outcomes of CAD patients.

Spironolactone and hyperkalemia in congestive heart failureIn 1999 Pitt and colleagues published the results of the RALES trial, an important study showing that the addition of a relatively small dose of the aldosterone antagonist spironolactone to a regimen that included angiotensin-converting enzyme (ACE) inhibitors for patients with severe congestive heart failure (NYHA Class III-IV) had a striking benefit on mortality

Achieving LDL cholesterol goals in elderly patients with ACSAfter an acute coronary syndrome (ACS) event, elderly patients are at greater risk of death and nonfatal coronary events compared with younger patients. Despite this, elderly patients continue to receive less evidence-based therapy. Lipidlowering therapy with statins is now routine practice for the secondary prevention of coronary heart disease. Achieving the optional National Cholesterol Expert Panel goal of a low-density lipoprotein cholesterol level of < 70 mg/dL for ACS patients over 70 years of age could prevent nearly 80 deaths or nonfatal coronary events for every 1000 patients treated for 2 years with a number needed to treat of approximately 12.

Inflammation, heart failure, and mortality in survivors of acute myocardial infarctionWe prospectively studied the relationship between C-reactive protein, obtained within 12 to 24 hours of symptom onset, and long-term risk of death and heart failure in survivors of acute myocardial infarction. The risk of death and heart failure increased progressively with increasing quartiles of C-reactive protein. We found a graded positive relationship between C-reactive protein levels and post-discharge mortality and heart failure.

Obesity-related hypertensionTo evaluate the interactions between the weight loss drug, sibutramine, and different antihypertensive treatments, we randomly assigned 171 subjects taking 3 antihypertensive treatment regimens to receive sibutramine or placebo. Our study showed for the first time that combination therapy with an angiotensin-converting enzyme inhibitor and a calcium channel blocker is more advantageous than a ß blocker/diuretic-based-regimen with regard to supporting the weight-reducing actions and metabolic changes induced by sibutramine.

Serial biomarker measurements in chronic heart failureCardiac troponin T (cTnT) and B-type natriuretic peptide (BNP) have been used to estimate prognosis in heart failure. However, most studies have evaluated decompensated patients using single measurements. To determine the value of serial measurements, we evaluated 190 stable chronic heart failure patients every 3 months during 2 years.
