Background: Equality in training opportunities, studying abroad, and satisfaction with work are not well investigated among Japanese cardiologists.Methods and Results: We studied cardiologists’ career development using a questionnaire that was emailed to 14,798 cardiologists belonging to the Japanese Circulation Society (JCS) in September 2022. Feelings regarding equality in training opportunities, preferences for studying abroad, and satisfaction with work were evaluated with regard to cardiologists’ age, sex, and other confounding factors. Survey responses were obtained from 2,566 cardiologists (17.3%). The mean (±SD) age of female (n=624) and male (n=1,942) cardiologists who responded to the survey was 45.6±9.5 and 50.0±10.6 years, respectively. Inequality in training opportunities was felt more by female than male cardiologists (44.1% vs. 33.9%) and by younger (<45 years old) than older (≥45 years old) (42.0% vs. 32.8%). Female cardiologists were less likely to prefer studying abroad (53.7% vs. 59.9%) and less satisfied with their work (71.3% vs. 80.8%) than male cardiologists. Increased feelings of inequality and lower work satisfaction were investigated among cardiologists who were young, had family care duties, and had no mentors. In the subanalysis, significant regional differences were found in cardiologists’ career development in Japan.Conclusions: Female and younger cardiologists felt greater inequality in career development than male and older cardiologists. A diverse workplace may prompt equality in training opportunities and work satisfaction for both female and male cardiologists.

Objectives: We aimed to identify which resting echocardiographic parameters can detect asymptomatic or mildly symptomatic patients with primary mitral regurgitation (MR) who require exercise stress echocardiography (ESE) to determine their suitability for surgery.Methods: We examined 56 consecutive patients with primary moderate/severe MR who underwent ergometer-based ESE. Patients who met the surgical indications at rest were excluded. Eligible patients were divided into Group I (pulmonary artery systolic pressure [PASP] during exercise >60 mmHg; n=11) and Group II (PASP during exercise ≤60 mmHg; n=30).Results: Forty-one patients were included. Group I was significantly older (65±12 vs. 54±14 years, P=0.042) and had significantly higher serum N-terminal pro-B-type natriuretic peptide concentrations than Group II (351±278 vs. 125±163 pg/mL, P=0.002). The univariate analysis demonstrated that peak E wave velocity (Group I vs. Group II: 125±45 vs. 101±24 cm/sec, P=0.050), left ventricular (LV) end-diastolic diameter index (32±4 vs. 30±3 mm/m2, P=0.035), and left atrial volume index (LAVI; 45±14 vs. 30±11 mL/m2, P=0.008) were predictors of increased PASP during exercise. In the multivariate analysis, resting LAVI best predicted exercise-induced pulmonary hypertension (hazard ratio 1.081 [95% confidence interval 1.009–1.158], P=0.028), with a cutoff value of 37 mL/m2.Conclusions: In asymptomatic or mildly symptomatic patients with primary moderate/severe MR, increased resting LAVI indicates the requirement for ESE, even without LV dilatation.

Background:The impact of chronic kidney disease (CKD) on long-term outcomes following acute myocardial infarction (AMI) in the era of modern primary PCI with optimal medical therapy is still in debate.Methods and Results:A total of 3,281 patients with AMI were enrolled in the J-MINUET registry, with primary PCI of 93.1% in STEMI. CKD stage on admission was classified into: no CKD (eGFR ≥60 mL/min/1.73 m2); moderate CKD (60>eGFR≥30 mL/min/1.73 m2); and severe CKD (eGFR <30 mL/min/1.73 m2). While the primary endpoint was all-cause mortality, the secondary endpoint was major adverse cardiac events (MACE), defined as a composite of all-cause death, cardiac failure, myocardial infarction (MI) and stroke. Of the 3,281 patients, 1,878 had no CKD, 1,073 had moderate CKD and 330 had severe CKD. Pre-person-days age- and sex-adjusted in-hospital mortality significantly increased from 0.014% in no CKD through 0.042% in moderate CKD to 0.084% in severe CKD (P<0.0001). Three-year mortality and MACE significantly deteriorated from 5.09% and 15.8% in no CKD through 16.3% and 38.2% in moderate CKD to 36.7% and 57.9% in severe CKD, respectively (P<0.0001). C-index significantly increased from the basic model of 0.815 (0.788–0.841) to 0.831 (0.806–0.857), as well as 0.731 (0.708–0.755) to 0.740 (0.717–0.764) when adding CKD stage to the basic model in predicting 3-year mortality (P=0.013; net reclassification improvement [NRI] 0.486, P<0.0001) and MACE (P=0.046; NRI 0.331, P<0.0001) respectively.Conclusions:CKD remains a useful predictor of in-hospital and 3-year mortality as well as MACE after AMI in the modern PCI and optimal medical therapy era.

Objective: To examine the clinical outcomes of optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) in patients presenting with ST-segment elevation myocardial infarction (STEMI).Methods: We retrospectively investigated 533 consecutive patients who underwent primary PCI for STEMI between June 2016 and December 2020. The primary endpoint was a target lesion failure (TLF; defined as a composite of cardiac death, target vessel myocardial infarction, or target lesion revascularization). Propensity score (PS) matching was performed to allow direct comparison of OCT-guided and intravascular ultrasound (IVUS)-guided PCI.Results: Patients in the OCT group (n=166) were younger than those in the IVUS group (n=367) and had a significantly higher left ventricular ejection fraction and estimated glomerular filtration rate. Killip class IV and left main stem disease were more common in the IVUS group. The median peak creatine kinase level was comparable between the two groups (1953 U/L vs 1603 U/L). A significantly larger amount of contrast was used in the OCT group (200 mL vs 165 mL; p<0.001). The cumulative incidence of TLF during a median follow-up of 2.2 years did not differ significantly between OCT and IVUS groups (9.6% vs 13.6%; p=0.221) but cardiac mortality was significantly higher in the IVUS group (8.7% vs 3.6%; p=0.047). After PS matching (n=161 in each group), there was no significant between-group difference in TLF or any other clinical outcome measures.Conclusions: OCT-guided PCI demonstrated clinical outcomes in patients with STEMI that were comparable to those of IVUS-guided PCI despite considerable differences in background characteristics.

Aim: We investigated the relationship between small dense low-density cholesterol (sdLDL-C) and risk of major adverse cardiovascular events (MACE) in patients treated with high- or low-dose statin therapy.Methods: This was a prospective case-cohort study within the Randomized Evaluation of Aggressive or Moderate Lipid-Lowering Therapy with Pitavastatin in Coronary Artery Disease (REAL-CAD) study, a randomized trial of high- or low-dose (4 or 1 mg/d pitavastatin, respectively) statin therapy, in patients with stable coronary artery disease (CAD). Serum sdLDL-C was determined using an automated homogenous assay at baseline (randomization after a rule-in period, >1 month with 1 mg/d pitavastatin) and 6 months after randomization, in 497 MACE cases, and 1543 participants randomly selected from the REAL-CAD study population.Results: High-dose pitavastatin reduced sdLDL-C by 20% than low-dose pitavastatin (p for interaction <0.001). Among patients receiving low-dose pitavastatin, baseline sdLDL-C demonstrated higher MACE risk independent of LDL-C (hazard ratio [95% confidence interval], 4th versus 1st quartile, 1.67 [1.04–2.68]; p for trend=0.034). High-dose (versus low-dose) pitavastatin reduced MACE risk by 46% in patients in the highest baseline sdLDL-C quartile (>34.3 mg/dL; 0.54 [0.36–0.81]; p=0.003), but increased relative risk by 40% in patients with 1st quartile (≤ 19.5 mg/dL; 1.40 [0.94–2.09]; p=0.099) and did not alter risk in those in 2nd and 3rd quartiles (p for interaction=0.002).Conclusions: These findings associate sdLDL-C and cardiovascular risk, independent of LDL-C, in statin-treated CAD patients. Notably, high-dose statin therapy reduces this risk in those with the highest baseline sdLDL-C.

Objectives: Malnutrition is associated with an increased risk of hospital readmission for heart failure in patients with acute decompensated heart failure (ADHF). Therefore, evaluation of the nutritional status in patients with ADHF may be important. The geriatric nutritional risk index (GNRI), the controlling nutritional status (CONUT) score, and the prognostic nutritional index (PNI) are widely used objective indexes for evaluation of the nutritional status. The present study was performed to determine the best nutritional index for predicting the prognosis in older adults with ADHF.Methods: We retrospectively studied 167 older adults (>65 years of age) who were admitted with ADHF from January 2012 to December 2015 and discharged alive. The objective nutritional status was evaluated using the GNRI, CONUT score, and PNI at admission. The endpoint of this study was unplanned hospitalization for worsening heart failure (WHF) within 1 year after discharge.Results: During the follow-up period, 58 patients were readmitted for WHF. In the multivariate Cox analysis, only the GNRI (p<0.0001) was independently associated with readmission for WHF among the three nutritional indexes. Kaplan–Meier analysis revealed that patients in the low-GNRI group (<90 as determined by receiver operating characteristic curve analysis) had a significantly greater risk of 1-year hospital readmission for WHF (p<0.0001; hazard ratio, 6.1; 95% confidence interval, 3.5–10.5).Conclusion: Among the objective nutritional indexes, the GNRI is the best predictor of readmission for WHF within 1 year after discharge in older adults with ADHF.

Objectives: There are benefits of exercise-based cardiac rehabilitation (CR) in patients with heart failure (HF), but their underlying molecular mechanisms remain elusive. The effect of CR on the expression profile of circulating microRNAs (miRNAs), which are short noncoding RNAs that regulate posttranscriptional expression of target genes, is unknown. If miRNAs respond to changes following CR for HF, then serum profiling of miRNAs may reveal cardioprotective mechanisms of CR.Methods: This study enrolled three hospitalized patients with progressed systolic HF and three normal volunteer controls. In patients, CR was initiated after improvement of HF, which included 2 weeks of bicycle ergometer and resistance exercises. Genome-wide expression profiling of circulating miRNAs was performed using microarrays for the patients (mean±SD age, 60.0±12.2 years) and controls (58.7±0.58 years). Circulating miRNA expression profiles were compared between patients with HF before and after CR and the controls.Results: Expression levels of two miRNAs were significantly different in patients before CR compared with controls and patients after CR. The expression of hsa-miR-125b-1-3p was significantly downregulated and that of hsa-miR-1290 was significantly upregulated in patients before CR.Conclusions: When performing CR, expression of certain circulating miRNAs in patients with HF is restored to nonpathological levels. The benefits of CR for HF may result from regulation of miRNAs through multiple effects of gene expression.

Background: Anaerobic threshold (AT) during cardiopulmonary exercise testing (CPET) is not always determinable in patients with heart failure (HF). However, little is known about the clinical features of patients with HF who have indeterminable AT. Therefore, the present study aimed to clarify the clinical features of such patients.Methods: A total of 70 patients with HF (58 males; age: 68±12 years) who underwent CPET during hospitalization were divided into two groups: determinable AT (n=50) and indeterminable AT (n=20). Physical function, echocardiographic results, and laboratory findings were subsequently determined.Results: Univariate analyses showed that the indeterminable AT group had significantly higher age and left ventricular ejection fraction, and significantly lower body mass index, calf circumference, handgrip strength, walking speed, serum hemoglobin, and serum albumin than the determinable AT group. Multiple logistic regression analysis identified handgrip strength and walking speed as independent predictive factors for indeterminable AT. Receiver-operating characteristic analyses revealed that handgrip strength of 21.2 kg and walking speed of 0.97 m/s were optimal cutoff values for differentiating patients who were likely to experience indeterminable AT.Conclusions: The present study identified handgrip strength and walking speed as powerful predictors for indeterminable AT with HF.
