MedicalResearch.com Interview with: Laura Maclagan, MSc. Epidemiologist, Cardiovascular Program ICES Central Toronto, Ontario M4N 3M5 MedicalResearch.com: What are the main findings of the study? Answer: We developed the CANHEART health index in order to measure the cardiovascular health of the Canadian population. The index is based on the prevalence of six health factors and behaviours known to be associated with cardiovascular health; being a non-smoker, being physically active, consuming at least 5 fruits and vegetables per day, having a low body mass index (BMI <25 kg/m²) and being free of diabetes and hypertension. The factors were summed to create an index ranging from 0 (worst) to 6 (best/ideal). We found that only 9.4% of Canadian adults age 20 and older met our definition of ideal cardiovascular health. 53.3% of adults were in intermediate cardiovascular health (4-5 healthy behaviours/factors) and 37.3% were in poor cardiovascular health (0-3 healthy behaviours). We found that the cardiovascular health of Canadians was stable over the 2003-2011 study period.

MedicalResearch.com Interview with: Dr. Evgeny Pokushalov, MD, PhD State Research Institute of Circulation Pathology, Rechkunovskaya 15, 630055 Novosibirsk 55, Russia MedicalResearch.com: What are the main findings of the study? Dr. Pokushalov: The main finding of this study is that after the failure of the first catheter ablation procedure for PAF, a redo ablation was more effective at eradicating recurrent AF than treatment with AAD. In this randomized controlled clinical trial, we observed that: 1. The AF progression rate was considerably higher in patients randomized to AAD (79%) use compared with patients treated with a second ablation procedure (25%). 2. The AF burden significantly increased on AAD during followup compared with patients of reablation group (18.8±11.4% versus 5.6±9.5%, respectively). 3. There was a much greater rate of progression to persistent AF if AAD was used rather than redo ablation (23% versus 4%, respectively). These findings support the need for consideration of a timely intervention in patients with PAF who have responded inadequately to an initial PVI.

MedicalResearch.com Interview with: Jonathan Hsu, MD, MAS Cardiac Electrophysiology, Division of Cardiology University of California, San Diego (UCSD) MedicalResearch.com: What are the main findings of the study? Dr. Hsu: We found that the prevalence of cardiac perforation during modern day ICD implantation is 0.14%. We also found that specific patient and implanter characteristics predict cardiac perforation risk: older age, female sex, left bundle branch block, worsened heart failure class, higher left ventricular ejection fraction, and non-single chamber ICD implant are associated with a greater odds of perforation, whereas atrial fibrillation, diabetes, previous cardiac bypass surgery, and higher implanter procedural volume are associated with a lower odds of perforation.
