The relationship between variables of 123-I-metaiodobenzylguanidine cardiac imaging and clinical status of the patients with diastolic heart failure

摘要: Abstract Background The status of cardiac sympathetic nerve activity in patients with diastolic heart failure has not been fully understood. 123-I-metaiodobenzylguanidine images are valuable for evaluating activity. Methods We obtained from 34 consecutive moderate and an ejection fraction ≥45%. Results decay-corrected washout rate correlated each plasma concentration brain natriuretic peptide (standardized correlation coefficient=0.305, p =0.254); a multivariate regression, the presence ischemic disease did predict rate. For 14 sinus rhythm, there was marginal negative between E / A velocity ratio transmitral flow coefficient=−0.518, Conclusions In failure, increases proportionally to severity disease.
