ACC.11 & i2 Summit

Highlights from the American College of Cardiology’s 2011 Annual Scientific Session and Innovation in Intervention: i2 Summit 2011 include stenting following CABG, yoga reducing AF, restless legs syndrome linked to CVD, and RF ablation for atrial fibrillation.   » Restless Legs Syndrome Linked to Heart Problems » Stents & the Prevention of Major Adverse Events  » RF Ablation Beneficial for AF Patients » Lung Transplants & Atrial Flutter » Can Yoga Reduce Atrial Fibrillation Episodes?  Restless Legs Syndrome Linked to Heart Problems [back to top] The Particulars: As the population continues to age, there has been an observed increase in the prevalence of sleep-related disorders and cardiovascular disease (CVD). Some studies have suggested that there might be a correlation between restless legs syndrome (RLS) and CVD. The recognition of frequent periodic leg movement during sleep as a potential modifiable risk factor for left ventricular hypertrophy may offer another target to help reduce the burden of CVD and associated complications. Data Breakdown: A study was conducted in 584 patients who were referred to a sleep lab for polysomnography and had baseline echocardiography. According to electromyography, 45% of patients experienced more than 35 periodic leg movements per hour (the threshold considered severe). Patients with more than 35 bursts of leg movement per hour while sleeping carried a 1.85-fold elevated risk of severe left ventricular hypertrophy. When compared with those who did not have severe periodic leg movements during sleep, those who did had more evidence of structural heart problems, including, higher left ventricular mass on average, higher left ventricular mass index, thicker interventricular septum, and thicker posterior wall.
