Abstract
BACKGROUND The relationship between induction and recurrence due to atrial tachycardia (AT) and left atrial (LA) matrix progression after atrial fibrillation (AF) ablation remains unclear. METHODS One hundred fifty-two consecutive patients with paroxysmal and persistent AF who underwent pulmonary vein isolation (PVI) and cavo-tricuspid isthmus (CTI) ablation and achieved sinus rhythm before the procedure were classified into three groups according to the AT pattern induced after the procedure: group N (non-induced), F (focal pattern), and M (macroreentrant pattern) in 3D mapping. RESULTS The total rate of AT induction was 19.7% (30/152) in groups F (n = 13) and M (n = 17). Patients in group M were older than those in groups N and F, with higher CHADS2/CHA2DS2-VASc values, left atrial enlargement, and low-voltage area (LVA) size of LA. The receiver operating characteristic curve determined that the cut-off LVA for macroreentrant AT induction was 8.8 cm2 (area under the curve [AUC]: 0.86, 95% confidence interval [CI]: 0.75-0.97). The recurrence of AT at 36 months in group N was 4.1% (5/122), and at the second ablation, all patients had macroreentrant AT. Patients with AT recurrence in group N had a wide LVA at the first ablation, and the cut-off LVA for AT recurrence was 6.5 cm2 (AUC 0.94, 95%CI 0.88-0.99). Adjusted multivariate analysis showed that only LVA size was associated with the recurrence of macroreentrant AT (odds ratio 1.21, 95%CI 1.04-1.51). CONCLUSIONS It is important to develop a therapeutic strategy based on the LVA size to suppress the recurrence of AT in these patients.

Abstract
The midterm prognosis of patients with deferred revascularization based on resting full-cycle ratio (RFR) or fractional flow reserve (FFR) is not well established. We investigated the midterm clinical outcomes of 137 consecutive patients with deferred revascularization of 177 coronary arteries based on RFR and FFR. Patients were classified into 3 groups (concordant normal, concordant abnormal, discordant FFR and RFR), using known cutoffs for FFR (≤0.80) and RFR (≤0.89). All-cause mortality occurred in 9 (6.6%) and major adverse cardiac events (MACEs) in 16 patients (11.7%). Concordant abnormal, age, body mass index (BMI), and current or history of cancer were associated with increased risks of all-cause mortality. In a multivariable model, current or history of cancer was significantly associated with all-cause death (hazard ratio [HR] 6.8, p = 0.02). Concordant abnormal, current or history of cancer, BMI, and left ventricular ejection fraction were associated with increased risk of MACE, and all predictors correlated significantly with MACE (abnormal concordance: HR 4.2, p = 0.043; current or history of cancer: HR 4.0, p = 0.047; BMI: HR 0.8, p = 0.020; left ventricular ejection fraction: HR 0.9, p = 0.017). Although these results support performing percutaneous coronary intervention according to evidence-based RFR or FFR thresholds, deferred lesions with discordant FFR and RFR results were not associated with worse prognosis.

Abstract
Abstract
Background
The importance of left ventricle diastolic dysfunction (LVDD) has been recognized widely, as it is well established that heart failure with preserved ejection fraction has a poor prognosis. Furthermore, N-terminal pro–B-type natriuretic peptide (NT-ProBNP) is used as a marker of heart failure. However, the association between LVDD and NT-proBNP is unclear.
Purpose
The aim of this study was to clarify the association between LVDD and NT-ProBNP.
Methods
In this study, an index based on gated myocardial perfusion SPECT using CardioREPO software for the diagnosis of LVDD was used. Out of the 171 patients who underwent myocardial perfusion imaging (MPI) between January 2015 and December 2018, 163 individuals (116 men and 47 women) completed MPI and NT-ProBNP. Patients were classified into 4 groups: NT-ProBNP levels below 125 pg/ml (n = 52), NT-ProBNP levels 125 to 400 pg/ml (n = 33), NT-ProBNP levels 400 to 900 pg/ml (n = 23), and NT-ProBNP levels over 900 pg/ml (n = 37). CardioREPO parameters (peak filling rate (PFR), 1/3 mean filling rate (MFR), and time to peak filling rate/R-R (TTPFR)) were compared between the 4 NT-ProBNP groups.
Results
Of the 163 patients, 55 had LVDD. The PFR and 1/3MFR were associated with LVDD. There was a statistically significant difference in PFR and 1/3 MFR between the NT-ProBNP levels below 125 pg/ml group and the NT-ProBNP levels 400 to 900 pg/ml group (PFR = 2.51+/-1.11 vs. 1.80+/-0.65, p = 0.001; 1/3 MFR = 1.41+/-0.55 vs. 1.06+/-0.47, p = 0.006, Table).
Conclusions
The MPI indices obtained by CardioREPO software were useful in the diagnosis of LVDD. The evaluation of LVDD by MPI correlated with NT-Pro BNP level is thought to have a clinical utility in the diagnosis and management of LVDD.

Abstract
BACKGROUND Recently, the frequency of patients who have glucose intolerance has been increasing in Japan. Glucose intolerance and insulin resistance/hyperinsulinemia are thought to influence the progression of atherosclerosis. The present study examined glucose tolerance, insulin resistance, post-prandial hyperglycemia/hyperinsulinemia and coronary risk factors by using 75 g oral glucose tolerance test (OGTT). PATIENTS AND METHODS Coronary risk factors were examined and OGTT with measurement of plasma glucose and serum insulin was done to evaluate the glucose metabolism and insulin resistance in 263 patients who underwent coronary angiography; 202 subjects were diagnosed as having coronary heart disease (CHD) and 61 subjects were normal. We compared the two groups. RESULTS The rate of having diabetes was significantly high in the CHD group. From the result of OGTT, 22.3% of CHD patients had diabetes mellitus and 36.6% had impaired glucose tolerance, thus the total glucose intolerance rate was 57.7% in the CHD group. No significant difference was noted in the homeostatic model assessment-R (HOMA-R), but glucose and insulin at 2 hours after OGTT were all significantly high in the CHD group. CONCLUSION The rate of glucose intolerance and the levels of post-prandial glucose and insulin were high in the CHD group. We concluded that the post-prandial hyperglycemia and hyperinsulinemia influenced the incidence of CHD.

Abstract
Noninvasive multigated equilibrium radionuclide ventriculography with krypton-81m (81mKr) was used to assess right heart relaxation in patients with chronic pulmonary diseases (CPD). The subjects consisted of 30 patients with CPD and 8 patients free of cardiopulmonary diseases admitted to our department. A region of interest (ROI) was selected on both the right atrium (RA) and right ventricle (RV). A time activity curve was obtained for each ROI. As a diastolic index of the right heart performance, the right atrial early emptying rate (RAER) was obtained from the right atrial time activity curve, while the right ventricular rapid filling rate (RVRFR) was obtained from the right ventricular time activity curve. The mean RAER was significantly lower in CPD patients compared with the control (CPD, 9.5 +/- 4.5; control, 16 +/- 3.4%/100 ms). Similarly, the mean RVRFR was significantly lower in CPD patients compared with the control (CPD, 27.3 +/- 9.9; control, 34 +/- 8.5%/100 ms). A strong negative correlation was noted between the mean pulmonary arterial pressure (mPAP) and RAER (r = -0.77; p < 0.001) and between the mPAP and the RVRFR (r = -0.63; p < 0.001). Our results suggest that RAER and RVRFR measured by 81mKr are clinically useful in the noninvasive assessment of right heart relaxation in patients with CPD.
