Abstract
Abstract
Introduction
Muscle, fat and bone mass may play some roles to keep physical activity and favorable outcome in patients with cardiovascular diseases. However, there is a paucity of data regarding the effects on the prognosis of skeletal muscle, fat, and bone mass in patients with ST-segment elevation myocardial infarction (STEMI).
Purpose
Our purpose was to examine whether skeletal muscle, fat, and bone mass each affect the prognosis after STEMI.
Methods
A total of 354 male patients with STEMI were enrolled in this study. Dual-energy X-ray absorptiometry scan was performed before discharge. All patients were followed up for the primary composite outcome of all-cause death, nonfatal myocardial infarction, nonfatal ischemic stroke, hospitalization for congestive heart failure, and unplanned revascularization.
Results
During a median follow-up of 32 months, 57 patients experienced primary composite outcome. Each of skeletal muscle, fat, and bone mass were indexed by height squared (kg/m2) and divided into two groups using the cut-off value obtained from the maximum Youden index to predict the primary composite outcome. The event rate was significantly higher in patients with low appendicular skeletal muscle mass index (ASMI) (29.2% vs 11.7%, p<0.001), low fat mass index (FMI) (22.9% vs 13.3%, p=0.030), and low bone mass index (23.8% vs 11.6%, p=0.002). After adjustment for age, renal function, diabetes mellitus, infarct size, Killip classification, and body mass index, low ASMI but not FMI (p=0.150) and bone mass index (p=0.159) was independently and significantly associated with the primary composite outcome (adjusted hazard ratio 2.12, 95%-confidence interval 1.05–4.31, p=0.035).
Conclusions
Index about muscle mass rather than fat and bone mass have prognostic impact in male patients with STEMI.

Abstract
Abstract
Background
In patients with non-ischemic cardiomyopathy (NICM), non-inducibility after catheter ablation has been associated with lower VT recurrence rates. We hypothesized that induced VT pleomorphism (PL-VT) may be indicative for a complex VT substrate that might be associated with poor ablation outcome independently of non-inducibility at the end of the procedure.
Methods
Consecutive patients with left-dominant NICM undergoing VT ablation (2008–2018) were included. All patients underwent genetic screening. PL-VT was defined as occurrence of ≥1 morphologically distinct QRS lasting for ≥6 consecutive beats during the same induced VT episode. Complete acute success was defined as non-inducibility of any VT at the end of procedure.
Results
Eighty-five patients (56±15 yrs, LVEF 38±12%), inducible for 365 VTs (median 3/patient, IQR 1–6) were included. PL-VT was observed in 29 patients (34%). Patients with PL-VT had more often anteroseptal substrates, a higher number of induced VTs, and larger endocardial bipolar (<1.5 mV) and unipolar low voltage (<8.01 mV) areas. Pathogenic genetic mutations were more frequently recognized in patients with PL-VT than in those without (59 vs. 34%, P=0.03), but there was no significant correlation in each representative mutation (Lamin A/C, Phospholamban, or Titin). Complete acute success was achieved in 34 patients (40%) and comparable between patients with PL-VT and those without (41 vs. 39%, P=0.85). After a median of 24 months, 53 patients (62%) had VT recurrence and 23 (27%) died. In multivariate Cox regression analysis, PL-VT and inducibility of any VT were significantly associated with VT recurrence (HR 4.07, CI 1.82–8.92; P=0.001, HR 2.22, CI 1.10–4.78; P=0.026, respectively) independent of NYHA, LVEF, electrical storm, genetic mutations, low voltage area, substrate location, and number of induced VTs. Of importance, the co-existence of PL-VT and persistent VT inducibility identified those at highest risk for VT recurrence after 2-years. (PL-VT (−)/complete success, 27%, PL-VT (−)/non-complete success, 50%, PL-VT (+)/complete success, 58%, PL-VT (+)/non-complete success 94%, Log-rank P<0.001, see figure).
Figure 1
Conclusions
Induced PL-VT was not associated with acute outcome but higher VT recurrence rate after catheter ablation in patients with NICM. Moreover, co-existence of PL-VT and persistent VT inducibility identifies patients at highest risk for VT recurrence whereas non-inducible patients without PL-VT have a favorable prognosis.

Abstract
Abstract
Background and purpose
Many reports have examined electrocardiographic (ECG) changes after subarachnoid hemorrhage from long ago; however, there are few reports on the prognosis of patients who have an ECG abnormality. Therefore, in this study, the prognoses of patients with subarachnoid hemorrhage showing abnormal ECG findings were retrospectively analyzed.
Methods
Over 30 months from January 2014 to June 2016, 199 patients (mean age, 61.1±17.0 years; 46.7% male) admitted with a subarachnoid hemorrhage (SAH) were enrolled. To assess the mechanism underlying abnormal ECG in the SAH, predictor variables, such as demographics (age, sex, and body surface area), hemodynamics (heart rate and systolic blood pressure), blood biochemical results, neurological assessments (Glasgow Coma Scale), and computed tomography (CT) severity classification (World Federation of Neurosurgical Societies classification) were recorded. The subarachnoid hemorrhage was classified into either the cerebral aneurysm rupture group (N=132) or traumatic subarachnoid hemorrhage group (N=67) and analyzed.
Results
In the cerebral aneurysm rupture group, the QT prolongation was significantly increased compared with the traumatic subarachnoid hemorrhage group (424.8±87.7 ms vs. 400.5±95.8 ms, P<0.05). There was a correlation between consciousness level (Glasgow Coma Scale) on admission and QT prolongation, and significant QT prolongation was observed in critical patients (Pearson's correlation coefficient test P=0.04). ST changes correlated with CT classification severity (WFNS classification), and the most severe group (WFNS Grade 5) showed significant ST changes. On admission, the cerebral aneurysm rupture group and 97.0% in the traumatic subarachnoid hemorrhage group.
Conclusions
Significantly prolonged QT and ST changes are noted in patients with severe aneurysmal subarachnoid hemorrhage. The cause of the ECG abnormality in subarachnoid hemorrhage patients is not yet understood. A small number of experimental animal models have shown that electrocardiogram abnormalities associated with subarachnoid hemorrhage develop in the brain stem, and an autonomic nerve abnormality may also be involved.
A D-dimer is positively correlated with both aneurysm trauma and traumatic subarachnoid hemorrhage and may be used for auxiliary diagnosis of a subarachnoid hemorrhage.

Abstract
Abstract
Background
Late renal function dysfunction is an increasingly recognized complication in continuous flow left ventricular assist device (CF-LVAD) patients. Although hemolysis is prevalent in CF-LVAD patients and hemolysis may deteriorate renal function, the influence of persistent hemolysis on renal function in CF-LVAD patients remains to be investigated.
Purpose
To investigate the influence of persistent hemolysis on renal function in CF-LVAD patients, using lactate dehydrogenase (LDH) as a sensitive marker of hemolysis.
Methods
Excluding patients who died or underwent pump exchange for pump thrombosis, we retrospectively reviewed 65 consecutive adults who underwent HeartMateII implantation in our center from May 2011 to October 2017. Patient characteristics, chronotropic change of estimated glomerular filtration rate (eGFR) and LDH values weekly for 4 weeks and every 4 weeks between 4 and 48 weeks after implantation were collected. Then, calculating mean LDH during 48 weeks after implantation, study population was divided into low and high mean LDH groups at the median value of mean LDH.
Results
The median value of mean LDH was 304 U/l. Compared with low LDH patients, though high LDH patients were more likely female and had smaller body surface area, there were no significant difference in pre-operative eGFR between the groups (66.0±23.7 vs. 70.2±25.7 ml/min/1.73m2, p=0.495). After 40 weeks after implantation, high LDH patients had significantly lower eGFR than low LDH patients (71.0±23.7 vs. 87.1±31.4 ml/min/1.73m2, p=0.024). In multivariate linear regression analysis, mean LDH [parameter estimate: −0.10 (95% CI: −0.17 to −0.04), p=0.003] and post-operative pulse pressure [parameter estimate: 0.71 (95% CI: 0.05 to 1.37), p=0.036] were significantly associated with eGFR change during 48 weeks after HeartMateII implantation.
Univariate and multivariate linear regression analysis for eGFR change Univariate parameter estimate 95% CI p value Multivariate parameter estimate 95% CI p value Bilirubin, mg/dl 9.97 3.82 to 16.13 0.002 6.55 −0.43 to 13.53 0.065 BNP, pg/ml 0.01 0.00 to 0.02 0.044 0.00 −0.01 to 0.01 0.528 Mean LDH during 4 to 48 weeks, U/l −0.11 −0.18 to −0.05 <0.001 −0.10 −0.17 to −0.04 0.003 Pre-operative right atrial pressure, mmHg 1.43 0.35 to 2.51 0.010 −0.06 −1.52 to 1.40 0.935 Post-operative pulse pressure, mmHg 0.77 0.03 to 1.52 0.042 0.71 0.05 to 1.37 0.036
Conclusions
High mean LDH and low pulse pressure were associated with a significant decrease in eGFR late after HeartMateII implantation. Subclinical persistent hemolysis may be associated with late renal function deterioration in CF-LVAD patients.

Abstract
Abstract
Introduction
Sarcopenia, characterized by the loss of skeletal muscle mass and muscle strength, has been demonstrated the importance in cardiovascular diseases including ST-segment elevation myocardial infarction (STEMI). However, there is few data comparing the effects on the prognosis of skeletal muscle mass of upper and lower extremities in STEMI patients.
Purpose
Our purpose was to examine whether skeletal muscle mass of upper and lower extremities affect the prognosis after STEMI.
Methods
A total of 432 patients with STEMI were enrolled in this study. Dual-energy X-ray absorptiometry scan was performed before discharge. Each of upper and lower extremity skeletal muscle masses was indexed by height squared (kg/m2), and divided into two groups using the first quartile value for each sex. All patients were followed up for the primary composite outcome of all-cause death, nonfatal myocardial infarction, nonfatal ischemic stroke, hospitalization for congestive heart failure, and unplanned revascularization.
Results
During a median follow-up of 32 months, 68 patients experienced primary composite outcome. The event rate was significantly higher in patients with low-lower extremity skeletal muscle mass index (LESMI) than in those with high-LESMI (24.3% vs 12.9%, log-rank p<0.001), as well as in those with low-upper extremity muscle mass index than in those with high-upper extremity muscle mass index (UESMI) (19.6% vs 14.5%, log-rank p=0.047). However, after adjustment for age, gender, renal function, diabetes mellitus, infarct size, body mass index, and body fat percentage, only low-LESMI was independently and significantly associated with the primary composite outcome (adjusted hazard ratio for LESMI 2.11, 95%-confidence interval 1.06–4.14, p=0.034, adjusted hazard ratio for UESMI 1.04, 95%-confidence interval 0.52–2.08, p=0.906,).
Conclusions
Decreased muscle mass of lower extremity, rather than upper extremity, might have prognostic impact in patients with STEMI.

Abstract
AIM Phase angle (PhA) can be determined through bioelectrical impedance analysis and is a unique variable for skeletal muscle. The objective of this study was to evaluate the relationship between PhA and muscle mass/quality in older adults. In addition, we attempted to determine the cutoff value of PhA for poor muscle function. METHODS Community-dwelling Japanese older men (n=285, 81.1±7.1 years) and women (n=724, 80.4±6.8 years) participated in this study and were classified into four groups based on the Asian Working Group for Sarcopenia (normal, presarcopenia, dynapenia, and sarcopenia). We measured PhA using bioelectrical impedance analysis, muscle quantity and quality indicators using ultrasonography, muscle strength, and physical performance and compared them in four groups. We also tried to determine the cutoff value of PhA for poor muscle function. RESULTS We found a significant difference in PhA among the four groups in men (P<0.05), and the dynapenia (3.61±0.75°) and sarcopenia groups (3.40±0.74°) showed significantly lower values than the normal group (4.50±0.86°) (P<0.05), but not the presarcopenia group (4.12±0.85°). In women, a significant difference was also observed among the four groups (P<0.05), and the dynapenia (3.41±0.65°) and sarcopenia groups (3.31±0.66°) showed significantly lower measures than the normal group (4.14±0.71°) (P<0.05), but not the presarcopenia group (4.07±0.51°). The receiver-operating characteristic curve analysis indicated the best cutoff value of PhA (men: 4.05°, women: 3.55°) to discriminate sarcopenia and dynapenia from normal and presarcopenia. CONCLUSION These findings suggest that PhA is a useful indicator for muscle function.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) is a well-recognized and potentially fatal complication of cardiac transplantation that commonly involves the gastrointestinal tract. Herein, we report a case of life-threatening gastrointestinal bleeding from recurrent terminal ileac ulcers mimicking PTLD in a heart recipient treated with everolimus (EVL). A 40-year-old man underwent heart transplantation for dilated cardiomyopathy 3 years prior to the current admission and was treated with tacrolimus and EVL. He was admitted to a local hospital because of fever, abdominal pain, and diarrhea. His symptoms persisted and, 3 weeks later, hematochezia occurred; thus, he was transferred to our hospital. As computed tomography and 18F-fluorodeoxyglucose positron emission tomography showed bowel-wall thickening of the terminal ileum, gastrointestinal PTLD was initially suspected. However, although colonoscopy- performed after switching EVL to mycophenolate mofetil (MMF)-showed terminal ileac ulcers, the histologic examination revealed no findings corresponding to PTLD. As EVL may delay ulcer healing, MMF was maintained for 3 months. After repeated colonoscopy showed ulcer healing, MMF was switched back to EVL for cardiac allograft vasculopathy prevention. Three weeks later, he was emergently admitted to a local hospital for life-threatening gastrointestinal bleeding from a recurrent terminal ileal ulcer, which required hemostatic forceps hemostasis. As EVL is suspected to be associated with recurrent ileal ulcers, EVL was again switched back to MMF. The ileal ulcers resolved, without recurrence in 3 months of clinical follow-up. This case demonstrates that cases of life-threatening gastrointestinal bleeding from recurrent terminal ileac ulcers can mimic PTLD in a heart recipient treated with EVL.

Abstract
OBJECTIVES We investigated the efficacy and safety of tacrolimus (TAC) by monitoring its serum concentration for mothers and infants in pregnant patients with systemic lupus erythematosus (SLE). METHODS We measured trough concentrations of TAC in 25 pregnant patients with SLE to assess influence of TAC on the disease activity. Additionally, we measured the concentrations of TAC in umbilical arterial blood, breast milk, and breastfed infants to investigate the safety of TAC for the mothers and infants. RESULTS The trough concentrations of TAC in the mothers significantly decreased in the second trimester as compared with those before pregnancy. However, the decrease in the trough concentrations of TAC did not lead to the deterioration of SLE. When examined, the doses of TAC were significantly lower in the second trimester and postpartum in the deteriorating group than those in the non-deteriorating group. There were no adverse events by TAC in mothers and fetuses. The concentrations of TAC in the umbilical cord blood were lower than those in the maternal blood. The relative infant dose in breastfed infants of TAC was < 1%. The level of TAC in infant bloods was below detectable limits. CONCLUSION These findings suggest that TAC is one of the most effective and safest immunosuppressive drugs for use in pregnant patients with SLE.

Abstract
Fetal myocardial performance index are used to assess aspects of systolic and diastolic function in developing fetal heart. The aim of this study was to determine normal values of fetal left ventricular (LV) Tei Index (TI) for measuring systolic performance and K-Index (KI) for diastolic performance in early (<;32 weeks), Mid (32-35 weeks) and late trimester (35-41 weeks) normal fetuses and fetuses with congenital heart diseases (CHD). Simultaneous recordings of Doppler Ultrasound Signal (DUS) of the LV outflow tracts and fetal electrocardiogram signals were obtained in 57 normal and 14 fetuses with CHD. CHDs were categorized in two types (conduction pathway abnormalities [8 cases] and structural anomalies [6 cases]). The LV isovolumic contraction time (ICT), isovolumic relaxation time (IRT), ventricular ejection time (VET) and ventricular filling time (VFT) were measured from amplitudes and peaks of high frequency component of DUS signals by an automated model. The TI and the new index were calculated by using the formula (ICT + IRT)/VET and (ICT + IRT)/VFT respectively. The TI did not show any significant change from CHD (conduction) to CHD (structural) fetuses (0.72± 0.09 vs 0.76±0.02; NS). On the other hand, KI showed significant decline in values (0.82±0.24 vs 0.49±0.34; p<;0.05) during normal development period and CHD with structural anomalies particularly. The correlation of KI with gestational ages was found to be negative and significant (r=- 0.29; p=0.025). Both TI and KI can be easily obtained in the fetus from DUS recording without the need for precise anatomic imaging. In conclusion, KI may be a useful tool to explore the healthy development of fetal myocardial function and identify fetuses with CHD (structural). More research is needed to check if KI could recognize the compromised fetuses from normal ones in future.
