Background: Although recent studies have suggested that height and body mass index (BMI) independently affect the prevalence of atrial fibrillation (AF), their combined effects have not been fully examined in Japanese patients. Methods and Results: Patients without organic cardiac diseases, hypertension and diabetes mellitus were screened from a prospective, single hospital-based cohort of the Shinken Database 2004-2007 (n=4,719). Both height and BMI significantly increased the crude rate of AF prevalence and the effects were significant even after adjustment by age, sex and left atrial dimension. The relative risks (RRs) for AF in the height and BMI categories were 2.07 (95% confidence interval [CI] 1.70-2.52) and 1.78 (95%CI 1.46-2.17), respectively, in the highest tertile compared with the lowest tertile. The RRs in the highest combined tertile was high to 2.98 (95%CI 2.07-4.28) compared with the lowest combined tertile, an unignorable figure for AF prevalence in the future. Conclusions: Height and BMI synergistically affected the prevalence of AF in Japanese patients. With respect to the recent increase in body size of the Japanese population, the present study predicts that there will be more occurrences of AF than previously predicted. (Circ J 2010; 74: 66 - 70)

Background: Right atrial pressure (RAP) is commonly estimated using inferior vena cava (IVC) diameter and its respirophasic variations. Although a guideline has been provided for estimation of RAP due to variation in IVC dimensions based on studies in Western subjects, echocardiographic values in Asian subjects are unknown. Methods and Results: We studied 369 patients who underwent IVC ultrasound within 24h of right heart catheterization (RHC). The maximum and minimum IVC diameter during a respiratory cycle and the percent collapse after a sniff test were measured. These IVC parameters were compared with mean RAP measured on RHC. Receiver operating characteristic curves were generated for each IVC parameter to determine the optimal cut-off to detect RAP >10mmHg. The IVC maximum diameter cut-off for detecting RAP >10mmHg was 19mm (sensitivity, 75%; specificity, 78%) and the percent collapse cut-off was 30% (sensitivity, 75%; specificity, 83%). Both cut-offs were smaller than those previously reported in patients from Western countries. When the cut-off values from the existing guideline were applied to the present cohort, the sensitivity and specificity for normal RAP (0–5mmHg) were 38.6% and 74.2%, respectively, and 60.0% and 92.0% for elevated RAP (>10mmHg). Conclusions: The optimal IVC maximum diameter and percent collapse cut-offs to detect elevated RAP were smaller in Asian subjects than in a previously reported Western cohort.

Background Although previous clinical trials demonstrated the non-inferiority of a rate control to rhythm control strategy for management of atrial fibrillation (AF), the optimal treatment strategy for paroxysmal AF (PAF) remains unclear. Methods and Results A randomized, multicenter comparison of rate control vs rhythm control in Japanese patients with PAF (the Japanese Rhythm Management Trial for Atrial Fibrillation (J-RHYTHM) study) was conducted. The primary endpoint was a composite of total mortality, symptomatic cerebral infarction, systemic embolism, major bleeding, hospitalization for heart failure, or physical/psychological disability requiring alteration of treatment strategy. In the study, 823 patients with PAF were followed for a mean period of 578 days. The primary endpoint occurred in 64 patients (15.3%) assigned to rhythm control and in 89 patients (22.0%) to rate control (P=0.0128). No significant differences between the treatment strategies were observed in the incidences of death, stroke, bleeding and heart failure. Meanwhile, significantly fewer patients requested changes of assigned treatment strategy in the rhythm control vs the rate control group, which was accompanied by improvement in AF-specific quality of life scores. Conclusion The J-RHYTHM study showed that rhythm control was associated with fewer primary endpoints than rate control. However, mortality and cardiovascular morbidity were not affected by the treatment strategy (umin-CTR No. C000000106). (Circ J 2009; 73: 242 - 248)
