Participant Questions 1. Concurrent anti-platelet therapy with VKA or LMWH?
VTE Wild Card:Two Studies You May Have Missed Matthew Rondina, MD University of Utah
JUPITER Study Design • N=17,802 healthy men and women • LDL < 130 mg/dL and hs-CRP ≥ 2.0 mg/L • Randomized to rosuvastatin 20mg daily or placebo • Median FU: 1.9y (max 5 yrs) • Occurrence to first VTE protocol-specified secondary endpoint • Intention-to-treat analysis Glynn RJ et al. N Eng J Med 2009;360:1851-61
Rosuvastatin 20mg Daily Reduced Risk of First VTE Glynn RJ et al. N Eng J Med 2009;360:1851-61
Effect Consistent Across Subgroups • Similar to reduction in arterial events • No association with LDL, HDL, TG, hs-CRP • Similar reductions for provoked and unprovoked VTE • No significant difference on early vs late events (>24 mos) • Effect consistent across subgroups • Gender • Age • BMI, waist circumference • Metabolic syndrome Glynn RJ et al. N Eng J Med 2009;360:1851-61
Expands role of statins for 1º VTE prevention Unknown if any benefit for 2º prevention May be statin-specific + Rosuva, ? + Simva No effect with pravastatin Suggested, but unproven, uses: VTE prophylaxis in cancer 2º prevention where AC is contraindicated Should Statins Be in the Water?

Pulmonary Embolism:RVE Increases Mortality Risk • RV Enlargement by Echo: • Defined as a RV diameter > 90% of the LV diameter in the long axis view • Associated with 6.6% in hospital mortality (vs. 1.9%; 2.6x risk) • Associated with 47% 30-day survival (versus 71% if normal RV diameter) • When combined with elevated TnI, 30-day survival is only 25% • Noninvasive and no contrast but may not be available 24/7 in all centers Chest 2008; 133:358-362 Chest 2008;133:334-336 Am J Card 2005;96:303-305

Are Prognostic Markers Useful for Identifying Higher-Risk APE for Thrombolytics? • Did not predict in-hospital PE-related AE • Did not predict 3-month PE-related mortality or VTE recurrence • May not be useful as guide to more aggressive therapy in APE with SBP ≥ 90 • Did predict 3-month all cause mortality • May reflect underlying comorbidities • Patients with normal markers had benign hospital course • Authors did not assess other outcomes • Exercise intolerance or dyspnea at rest • Persistent RV dysfunction or pulmonary HTN Bova et al, J Thromb Haemost 2009;7:938-944 Kline JA.
