However, this is not the case between lipids and heart failure. Ironically, high lipid levels are associated with better outcomes in heart failure, but the mechan-isms underlying the phenomenon are not fully understood. This study was performed to test the hypothesis that reduced intestinal lipid absorption due to venous congestion may lead to low lipid levels.MethodsWe collected data of clinical characteristics, echocardio-graph, and lipid profile in 442 unselected patients with congestive heart failure. Correlations between lipid levels[including total cho-lesterol（TCL）, high-density lipoprotein cholesterol（HDL-C）, low-density lipoprotein cholesterol（LDL-C）, and triglycerides（TG）]and right ventricle end diastolic diameter （RVEDD）, left ventricle end diastolic diameter （LVEDD）, right atrium diameter （RA）, left atrium diameter （LA）, or left ventricle ejection fraction （LVEF） were analyzed using Pearson correlation and partial correlation. RVEDD, LVEDD, RA, and LA were indexed to the body surface area.ResultsThere was a significantly inverse correlation between TCL le-vels and RVEDD （r=-0.34,P〈0.001） and RA （r=-0.36,P〈0.001）. Other lipids such as LDL-C, HDL-C, and TG had asimilar inverse correlation with RVEDD and RA. All these correlations remained unchanged after adjusting for age, gender, smoking status, physical activity levels, comorbidities, and medication use.ConclusionsLipid levels were inversely correlated to RVEDD in patients with congestive heart failure; however, because this was an observational study, further investigation is needed to verify our results as wellas identify a causal relationship, if any.展开更多

The age range of patients was 21-50, with a mean of 38.5 years. Ten out of 12 were females, 1 patient had candia failure due to almost incessant VT while the rest had normal left ventricular function. Twelve pts had VT arising from the right ventricle; of those, 9 were from the outflow truct, 2 from the RV apex, and 1 from the RV inflow. In all pts the diagnostic study and therapeutic RFA were combined in a single procedure. Pacemapping and local activition time were used to guide the site of RFA in pts with VT arising from the right ventricle. RFA was successful in 11 of the 12 pts(91 % ). Number of RF applications were 1 -27, mean 9. 6;fluo- roscopy time were 4-75, mean 26. 9 minutes. RFA for idiopathic RV has a high success rate. This mode of treatment should be considered as a nonpharmacological curative treatment for symptomatic pts.展开更多
