Abstract
Background Chromogranin A (CgA) levels have been reported to predict mortality in patients with heart failure. However, information on the prognostic value and clinical availability of CgA is limited. We compared the prognostic value of CgA to that of previously proven natriuretic peptide biomarkers in patients with acute heart failure. Methods We retrospectively evaluated 272 patients (mean age, 68.5±15.6 years; 62.9% male) who underwent CgA test in the acute stage of heart failure hospitalization between June 2017 and June 2018. The median follow-up period was 348 days. Prognosis was assessed using the composite events of 1-year death and heart failure hospitalization. Results In-hospital mortality rate during index admission was 7.0% (n=19). During the 1-year follow-up, a composite event rate was observed in 12.1% (n=33) of the patients. The areas under the receiver-operating characteristic curves for predicting 1-year adverse events were 0.737 and 0.697 for N-terminal pro-B-type natriuretic peptide (NT-proBNP) and CgA, respectively. During follow-up, patients with high CgA levels (>158 pmol/L) had worse outcomes than those with low CgA levels (≤158 pmol/L) (85.2% vs. 58.6%, p<0.001). When stratifying the patients into four subgroups based on CgA and NT-proBNP levels, patients with high NT-proBNP and high CgA had the worst outcome. CgA had an incremental prognostic value when added to the combination of NT-proBNP and clinically relevant risk factors. Conclusion The prognostic power of CgA was comparable to that of NT-proBNP in patients with acute heart failure. The combination of CgA and NT-proBNP can improve prognosis prediction in these patients.

Abstract
There is insufficient information on the relationship between the N-terminal pro-brain natriuretic peptide (NT-proBNP) level and collateral circulation (CC) formation after primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction. We analyzed 857 patients who underwent primary PCI. The serum NT-proBNP levels were measured on the day of admission, and the CC was scored according to Rentrop’s classification. Log-transformed NT-proBNP levels were significantly higher in patients with good CC compared to those with poor CC (6.13 ± 2.01 pg/mL versus 5.48 ± 1.97 pg/mL, p < 0.001). The optimum cutoff value of log NT-proBNP for predicting CC was 6.04 pg/mL. Log NT-proBNP ≥ 6.04 pg/mL (odds ratio 2.23; 95% confidence interval 1.51–3.30; p < 0.001) was an independent predictor of good CC. CC development was higher in patients with a pre-TIMI flow of 0 or 1 than those with a pre-TIMI flow of 2 or 3 (22.6% versus 8.8%, p = 0.001). The incidence of left ventricular (LV) dysfunction (< 50%) was greater in patients with a pre-TIMI flow of 0 or 1 (49.8% versus 35.5%, p < 0.001). The release of NT-proBNP was greater in patients with LV dysfunction (34.3% versus 15.6%, p < 0.001). The incidence of good CC was greater in patients with log NT-proBNP levels ≥ 6.04 pg/ml (16.8% versus 26.2%, p = 0.003). The association between NT-proBNP and collateral formation was not influenced by pre-TIMI flow and LV function. NT-proBNP appears to reflect the degree of collateral formation in the early phase of STEMI and might have a new role as a useful surrogate biomarker for collateral formation in patients undergoing primary PCI.

Abstract
Objective Fimasartan, an angiotensin II type 1 receptor blocker, and linagliptin, a dipeptidyl-peptidase-4 inhibitor, are frequently coadministered to treat patients with hypertension and diabetes, respectively. This study sought to evaluate the pharmacokinetic interactions between fimasartan and linagliptin after co-administration in healthy Korean subjects. Methods The overall study was divided into two separate parts, with each part designed as an open-label, multiple-dose, two-period, and single-sequence study. In Part A, to investigate the effect of linagliptin on fimasartan, 25 subjects received 120 mg fimasartan alone once daily for seven days during Period I, and 120 mg fimasartan with 20 mg linagliptin for seven days during Period II. In Part B, to examine the effect of fimasartan on linagliptin, 12 subjects received only linagliptin once daily for seven days during Period I, followed by concomitant administration of fimasartan for seven days during Period II, at the same doses used in Part A. Serial blood samples were collected at scheduled intervals for up to 24 h after the last dose to determine the steady-state pharmacokinetics of both drugs. Results Thirty-six subjects completed the study. The geometric mean ratio and 90% confidence intervals for maximum plasma concentration at steady state (Cmax,ss) and area under the concentration–time curve at steady state (AUCτ,ss) of fimasartan with or without linagliptin were 1.2633 (0.9175–1.7396) and 1.1740 (1.0499–1.3126), respectively. The corresponding values for Cmax,ss and AUCτ,ss of linagliptin with or without fimasartan were 0.9804 (0.8480–1.1336) and 0.9950 (0.9322–1.0619), respectively. A total of eight adverse events (AEs) were reported and the incidence of AEs did not increase significantly with co-administration of the drugs. Conclusion Our results suggest that there are no clinically significant pharmacokinetic interactions between fimasartan and linagliptin when co-administered. Treatments were well tolerated during the study, with no serious adverse effects. Clinical Trial Registry http://clinicaltrials.gov, NCT03250052.

Derivation and validation of a combined in-hospital mortality and bleeding risk model in acute myocardial infarction. IJC HEART & VASCULATURE 2021; 33:100732. [PMID: 33665352 PMCID: PMC7907424 DOI: 10.1016/j.ijcha.2021.100732] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Revised: 01/08/2021] [Accepted: 01/28/2021] [Indexed: 12/22/2022]
Abstract
Background In the potent new antiplatelet era, it is important issue how to balance the ischemic risk and the bleeding risk. However, previous risk models have been developed separately for in-hospital mortality and major bleeding risk. Therefore, we aimed to develop and validate a novel combined model to predict the combined risk of in-hospital mortality and major bleeding at the same time for initial decision making in patients with acute myocardial infarction (AMI). Methods Variables from the Korean Acute Myocardial Infarction Registry (KAMIR) - National Institute of Health (NIH) database were used to derive (n = 8955) and validate (n = 3838) a multivariate logistic regression model. Major adverse cardiovascular events (MACEs) were defined as in-hospital death and major bleeding. Results Seven factors were associated with MACE in the model: age, Killip class, systolic blood pressure, heart rate, serum glucose, glomerular filtration rate, and initial diagnosis. The risk model discriminated well in the derivation (c-static = 0.80) and validation (c-static = 0.80) cohorts. The KAMIR-NIH risk score was developed from the model and corresponded well with observed MACEs: very low risk (0.9%), low risk (1.7%), moderate risk (4.2%), high risk (8.6%), and very high risk (23.3%). In patients with MACEs, a KAMIR-NIH risk score ≤ 10 was associated with high bleeding risk, whereas a KAMIR-NIH risk score > 10 was associated with high in-hospital mortality. Conclusion The KAMIR-NIH in-hospital MACEs model using baseline variables stratifies comprehensive risk for in-hospital mortality and major bleeding, and is useful for guiding initial decision making.

Abstract
This study sought to determine hospital variation in the use of follow-up stress testing (FUST) and invasive coronary angiography (FUCAG) after percutaneous coronary intervention (PCI). The claims records of 150,580 Korean patients who received PCI in 128 hospitals between 2008 and 2015 were analyzed. Patient were considered to have undergone FUST and FUCAG, when these testings were performed within two years after discharge from the index hospitalization. Hierarchical generalized linear and frailty models were used to evaluate binary and time-to-event outcomes. Hospital-level risk-standardized FUCAG and FUST rates were highly variable across the hospitals (median, 0.41; interquartile range [IQR], 0.27–0.59; median, 0.22; IQR, 0.08–0.39, respectively). The performances of various models predicting the likelihood of FUCAG and FUST were compared, and the best performance was observed with the models adjusted for patient case mix and individual hospital effects as random effects (receiver operating characteristic curves, 0.72 for FUCAG; 0.82 for FUST). The intraclass correlation coefficients of the models (0.41 and 0.68, respectively) indicated that a considerable proportion of the observed variation was related to individual institutional effects. Higher hospital-level FUCAG and FUST rates were not preventive of death or myocardial infarction. Increased repeat revascularizations were observed in hospitals with higher FUCAG rates.

Abstract
Objective: To explore the relationship between premature atrial complexes (PACs) and recurrence of atrial fibrillation (AF). Methods: Published literature was searched in PubMed, Embase, Web of Science, Cochrane, Weipu, China national knowledge infrastructure, Wanfang and China Biology Medicine disc up to 25 March 2020. RevMan5.3 software was used to analyzed the data and publication bias was performed by Stata 15.1. Results: A total of 8 studies were identified, including 1 252 AF patients with a mean age of 61.67 years, and male patients accounted for 70.6%. During follow-up, AF recurred in 425 cases. Meta-analysis showed that frequent PACs was an independent risk factor for recurrence of AF (HR=2.64, 95%CI:1.40-4.97). Subgroup analyses showed that PACs not only increasedthe risk of recurrence of AF after electrical cardioversion (HR=2.38, 95%CI:1.25-4.51), but also significantly increased the risk of recurrence of AF after catheter ablation cardioversion (HR=2.90, 95%CI:1.11-7.60). Conclusions: PACs is significantly associated with AF recurrence.

Abstract
BACKGROUND Data regarding the association between preexisting cardiovascular risk factors (CVRFs) and cardiovascular diseases (CVDs) and the outcomes of patients requiring hospitalization for coronavirus disease 2019 (COVID-19) are limited. Therefore, the aim of this study was to investigate the impact of preexisting CVRFs or CVDs on the outcomes of patients with COVID-19 hospitalized in a Korean healthcare system. METHODS Patients with COVID-19 admitted to 10 hospitals in Daegu Metropolitan City, Korea, were examined. All sequentially hospitalized patients between February 15, 2020, and April 24, 2020, were enrolled in this study. All patients were confirmed to have COVID-19 based on the positive results on the polymerase chain reaction testing of nasopharyngeal samples. Clinical outcomes during hospitalization, such as requiring intensive care and invasive mechanical ventilation (MV) and death, were evaluated. Moreover, data on baseline comorbidities such as a history of diabetes, hypertension, dyslipidemia, current smoking, heart failure, coronary artery disease, cerebrovascular accidents, and other chronic cardiac diseases were obtained. RESULTS Of all the patients enrolled, 954 (42.0%) had preexisting CVRFs or CVDs. Among the CVRFs, the most common were hypertension (28.8%) and diabetes mellitus (17.0%). The prevalence rates of preexisting CVRFs or CVDs increased with age (P < 0.001). The number of patients requiring intensive care (P < 0.001) and invasive MV (P < 0.001) increased with age. The in-hospital death rate increased with age (P < 0.001). Patients requiring intensive care (5.3% vs. 1.6%; P < 0.001) and invasive MV (4.3% vs. 1.7%; P < 0.001) were significantly greater in patients with preexisting CVRFs or CVDs. In-hospital mortality (12.9% vs. 3.1%; P < 0.001) was significantly higher in patients with preexisting CVRFs or CVDs. Among the CVRFs, diabetes mellitus and hypertension were associated with increased requirement of intensive care and invasive MV and in-hospital death. Among the known CVDs, coronary artery disease and congestive heart failure were associated with invasive MV and in-hospital death. In multivariate analysis, preexisting CVRFs or CVDs (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.07-3.01; P = 0.027) were independent predictors of in-hospital death after adjusting for confounding variables. Among individual preexisting CVRF or CVD components, diabetes mellitus (OR, 2.43; 95% CI, 1.51-3.90; P < 0.001) and congestive heart failure (OR, 2.43; 95% CI, 1.06-5.87; P = 0.049) were independent predictors of in-hospital death. CONCLUSION Based on the findings of this study, the patients with confirmed COVID-19 with preexisting CVRFs or CVDs had worse clinical outcomes. Caution is required in dealing with these patients at triage.

Abstract
AIM The main aim of this study was to compare the long-term outcome of a conventional colorectal endoscopic submucosal dissection (ESD) in which submucosal dissection was continued throughout until the completion of resection (ESD-T) to hybrid endoscopic submucosal dissection (ESD-H) in the colorectum. METHOD Medical records of 836 colorectal neoplasia patients treated by ESD-T or ESD-H were reviewed. ESD-H was defined as colorectal ESD with additional snaring in the final stage of the procedure. Primary outcomes were the overall and metastatic recurrence rates. Secondary outcomes were short-term outcomes such as the en bloc resection rate, procedure time and adverse events. RESULTS The overall recurrence rate was higher in the ESD-H than in the ESD-T group (5.7% vs 0.7%, P = 0.001). The metastatic recurrence rate showed no significant difference between these groups (1.4% vs 1.4%, P = 1.000). Multivariate analysis revealed that a failed en bloc resection (hazard ratio 24.097; 95% CI 5.446-106.237; P < 0.001) and larger tumour size (hazard ratio 1.042; 95% CI 1.014-1.070; P = 0.003) were independently associated with overall recurrence. The ESD-H group showed a lower en bloc resection rate (56.8% vs 96.5%, P < 0.001), shorter procedure time (45.6 vs 54.3 min, P < 0.001) and higher perforation rate (10.3% vs 6.0%, P = 0.029). CONCLUSION Although long-term outcomes in terms of overall recurrence are inferior following ESD-H, a failed en bloc resection and large tumour size are the only independent risk factors for recurrence. Further investigations are warranted to improve the long-term outcomes of ESD-H.

Abstract
BACKGROUND The association of N-terminal pro-B type natriuretic peptide (NT-proBNP) and plasma renin activity (PRA) for the prognosis of the patients with acute heart failure (HF) has not been fully investigated. This study aimed to determine the association between NT-proBNP and PRA and to investigate the incremental value of PRA to NT-proBNP for predicting long term prognosis in patients with acute HF. METHODS Three hundred and ninety-six patients (mean age, 64.7 ± 15.9 years; 46.5% female) presenting with acute HF were enrolled between December 2004 and July 2013. Patients with newly diagnosed HF as well as patients with acute exacerbated chronic HF were included. The prognosis was assessed with the composite event of all-cause mortality and readmission for HF during a 2-year follow-up period. RESULTS The etiology of HF was ischemic in 116 (29.3%) patients. In a Cox proportional hazards model, log-transformed PRA (hazard ratio [HR], 1.205; P = 0.007) was an independent predictor of the composite outcome of all-cause mortality and readmission for HF in addition to age (HR, 1.032; P = 0.001), white blood cell (WBC) count (HR, 1.103; P < 0.001), and left ventricular ejection fraction (LVEF) (HR, 0.978; P = 0.013). Adding PRA to age, sex, LVEF, and NT-proBNP significantly improved the prediction for the composite outcome of all-cause mortality and readmission for HF, as shown by the net reclassification improvement (0.47; P < 0.001) and integrated discrimination improvement (0.10; P < 0.001). CONCLUSION PRA could provide incremental predictive value to NT-proBNP for predicting long term prognosis in patients with acute HF.

Abstract
Background This study aimed to investigate the incidences of and risk factors for perioperative events following anticoagulant discontinuation in patients with non-valvular atrial fibrillation (NVAF) undergoing non-cardiac surgery. Methods A total of 216 consecutive patients who underwent cardiac consultation for suspending perioperative anticoagulants were enrolled. A perioperative event was defined as a composite of thromboembolism and major bleeding. Results The mean anticoagulant discontinuation duration was 5.7 (±4.2) days and was significantly longer in the warfarin group (p<0.001). Four perioperative thromboembolic (1.9%; three strokes and one systemic embolization) and three major bleeding events (1.4%) were observed. The high CHA2DS2-VASc and HAS-BLED scores and a prolonged preoperative anticoagulant discontinuation duration (4.4±2.1 vs. 2.9±1.8 days; p=0.028) were associated with perioperative events, whereas the anticoagulant type (non-vitamin K antagonist oral anticoagulants or warfarin) was not. The best cut-off levels of the HAS-BLED and CHA2DS2-VASc scores were 3.5 and 2.5, respectively, and the preoperative anticoagulant discontinuation duration for predicting perioperative events was 2.5 days. Significant differences in the perioperative event rates were observed among the four risk groups categorized according to the sum of these values: risk 0, 0%; risk 1, 0%; risk 2, 5.9%; and risk 3, 50.0% (p<0.001). Multivariate logistic regression analysis showed that the HAS-BLED score was an independent predictor for perioperative events. Conclusion Thromboembolic events and major bleeding are not uncommon during perioperative anticoagulant discontinuation in patients with NVAF, and interrupted anticoagulation strategies are needed to minimize these.

Abstract
This study compared the pharmacokinetics of a fixed-dose combination (FDC) of candesartan (16 mg) and amlodipine (10 mg) versus coadministration of individual formulations to clarify the bioequivalence of the FDC. In this randomized, open-label, single-dose, 2-treatment, 2-way crossover study, healthy Korean volunteers received a single dose of candesartan (16 mg) with amlodipine (10 mg) as either an FDC or single agents concomitantly administered, with a 2-week washout period. Serial blood samples were collected up to 72 hours after dosing for each treatment period, and plasma concentrations of candesartan and amlodipine were measured using a validated liquid chromatography-tandem mass spectrometry method. A total of 39 subjects completed the study. The geometric mean ratios (GMRs) and 90% confidence intervals (CIs) for the area under the plasma concentration-time curve from time 0 to the last measurement (AUC0-t) and the peak plasma concentration (Cmax) for candesartan were 1.0182 (0.9562–1.0841) and 0.9492 (0.8726–1.0324), respectively. The GMR and 90% CI for the AUC0-t and Cmax for amlodipine were 1.0552 (1.0255–1.0857) and 1.0668 (1.0259–1.1094), respectively. In conclusion, the new FDC formulation of candesartan (16 mg) and amlodipine (10 mg) was bioequivalent to the concomitant administration of single agents. A single dose of candesartan/amlodipine as the FDC or as single agents was well tolerated.

Abstract
A 60-year-old male patient with coronavirus disease-2019 showed new onset ST-segment elevation in V1-V2 leads on electrocardiogram and cardiac enzyme elevation in intensive care unit. He had a history of type 2 diabetes mellitus, hypertension, and dyslipidemia. He was receiving mechanical ventilation and veno-venous extracorporeal membrane oxygenation treatment for severe hypoxia. Two-D echocardiogram showed regional wall motion abnormalities. We performed primary percutaneous coronary intervention for acute myocardial infarction complicating cardiogenic shock under hemodynamic support. He expired on the 16th day of admission because of cardiogenic shock and multi-organ failure. Active surveillance and intensive treatment strategy are important for saving lives of COVID-19 patients with acute myocardial infarction.

Abstract
Coronavirus disease 2019 (COVID-19) is a highly contagious disease caused by the novel virus severe acute respiratory syndrome coronavirus 2. The first case developed in December, 2019 in Wuhan, China; several months later, COVID-19 has become pandemic, and there is no end in sight. This disaster is also causing serious health problems in the area of cardiovascular intervention. In response, the Korean Society of Interventional Cardiology formed a COVID-19 task force to develop practice guidelines. This special article introduces clinical practice guidelines to prevent secondary transmission of COVID-19 within facilities; the guidelines were developed to protect patients and healthcare workers from this highly contagious virus. We hope these guidelines help healthcare workers and cardiovascular disease patients around the world cope with the COVID-19 pandemic.

Abstract
Objective: To explore the value of nucleic acid detection methods in pharyngeal swabs in the etiological diagnosis of Mycoplasma pneumoniae (MP) infection in children. Methods: Four hundred and fifty-four (male 210, female 244) children with pneumonia in Department of Pulmonology, Children's Hospital of Zhejiang University School of Medicine were enrolled from July, 2018 to October, 2018. Pharyngeal swabs and venous blood were obtained on the first or the second day after hospitalization. Fluorescence detection quantitative amplification of DNA, thermostatic amplification of RNA, MP culture and MP-IgM were used to detect MP simultaneously. MP infection is diagnosed if MP culture is positive or the two of the other three methods are positive. Pharyngeal swabs were acquired and detected using fluorescence quantitative amplification of DNA, thermostatic amplification of RNA and MP culture again for children with confirmed MP infection before discharge. The detection rates and quantitative changes of the three methods were compared, and χ(2) test was used for comparison among groups. Results: A total of 454 hospitalized children with pneumonia were included in this study. The detection rates of fluorescence quantitative amplification of DNA, thermostatic amplification of RNA, MP culture and MP-IgM IgM were 43.6% (198/454), 43.2% (196/454), 40.0% (180/454) and 30.6% (139/454) respectively. The difference of detection rates of the four methods was statistically significant (χ(2)=20.8, P<0.05),but no significant difference between the detection rates of fluorescence quantitative amplification of DNA and thermostatic amplification of RNA was found (χ(2)=0.018, P=0.900). They both had higher detection rates than MP-IgM or MP culture. MP infection is diagnosed if MP culture is positive or the two of the other three methods are positive, and two hundred and nine children were diagnosed as MP infection. In the second test of MP infection in 209 children before discharge, the positive rate of MP culture was 67.5% (141/209), with 39.4% (13/33) changed from negative to positive, and 27.3% (48/176) changed from positive to negative. The positive rate of thermostatic amplification of RNA was 82.3% (172/209), with 16.2% (31/191) turned from positive to negative, and 66.7% (12/18) turned from negative to positive. The positive rate of fluorescence quantitative amplification of DNA was 67.0% (140/209), with 52.9% (18/34) cases changed from negative to positive, and 30.3% (53/175) cases changed from positive to negative. MP-DNA load decreased in 141 cases (67.5%) and increased in 68 cases (32.5%) in the second test among the positive samples tested by fluorescence quantitative amplification of DNA. The detection rates of the four methods in the non-severe group and the severe group were similar, and the differences among the groups were not statistically significant (all P>0.05). In the second test, the proportion of changing from negative to positive in the severe group was higher than that in the non-severe group, but only the difference in the thermostatic amplification of RNA was statistically significant (P=0.038) and the cases of changing from negative to positive of thermostatic amplification of RNA in the severe group and non-severe group are 7 and 5 respectively. Conclusions: The methods of pharyngeal swab nucleic acid detection have high sensitivity and application value in the etiological diagnosis of acute MP infection in children. The results of fluorescence quantitative amplification of DNA and thermostatic amplification of RNA are highly consistent, and they are both more advantageous than MP-IgM. Repeated testing in the acute phase is helpful to find MP infection children whose first test is negative. The load of MP-DNA did not decrease in some children in the acute stage after antibiotic treatment.

Abstract
Abstract
Background
Recent blood pressure guidelines recommend intensive blood pressure control in diabetic patients with cardiovascular disease.
Purpose
We sought to investigate combined impact of intensive blood glucose lowering and blood pressure control on clinical outcome in diabetic patients with acute myocardial infarction (AMI) has not been fully investigated yet.
Method
Korean Acute Myocardial Infarction Registry (KAMIR) – National Institute of Health (NIH) database included 12,179 patients (9,046 men; mean age = 63.6±12.6 year-old) who were discharged alive. Among them, 3,430 (28.2%) had a diabetes mellitus (DM). MACCEs were defined as a composition of all cause death, non-fatal MI, repeat revascularizations including repeated percutaneous coronary intervention and coronary bypass grafting, cerebrovascular accident and rehospitalizations at 1 year. This research was supported by a fund by Research of Korea Centers for Disease Control and Prevention.
Result
We determined cut-off value of discharge systolic blood pressure (SBP) to predict 1-year MACCE in DM and non-DM patients. Discharge SBP of less than 130mmHg was associated with a lower MACCE at 1 year compared to SBP level of 130mmHg or greater (10.8% versus 15.4%; log-rank p=0.001) in DM patients, whereas discharge SBP cut-off level was 140mmHg to discriminate 1-year MACCE in non-DM patients (6.4% versus 8.5%, log-rank p=0.045). In DM patients, there were no significant difference in 1-year MACCEs between patients with HbA1c less than 7% versus 7% or greater (12.0% versus 10.7%; log-rank p=0.325). DM patients were categorized into 4 groups; discharge SBP <130mmHg and HbA1c <7% (Group 1); discharge SBP <130mmHg and HbA1c ≥7% (Group 2); discharge SBP ≥130mmHg and HbA1c <7% (Group 3); discharge SBP ≥130mmHg and HbA1c ≥7% (Group 4). Intensive BP control was associated lower 1-year MACCEs in patients with good glycemic control (Group 1 & 3; 10.7% versus 16.7%; log-rank p=0.009). However, in patients with poor glycemic control, intensive BP control did not improve 1-year MACCEs (Group 2 & 4; 10.6% versus 11.1%; log-rank p=0.761).
Conclusion
Strict BP control is more important than glycemic control to improve short-term clinical outcome in DM patients with AMI. However, in patients with poor glycemic control, strict BP control did not improve clinical outcome.

Abstract
Abstract
Background
Current guideline recommends potent antiplatelet agents and transradial intervention. However, it is uncertain whether routine use of IVUS, thrombus aspiration and glycoprotein IIB-IIIA inhibitor is beneficial for improving clinical outcome in patients with ST-segment elevation myocardial infarction (STEMI).
Purpose
The aim of this study was to investigate optimal procedural strategy to improve clinical outcome.
Methods
A total of 6,046 patients who underwent primary percutaneous coronary intervention (PCI) for STEMI were analyzed from the Korean Acute Myocardial Infarction Registry (KAMIR) – National Institute of Health (NIH) database. MACCEs were defined as a composition of all cause death, non-fatal MI, repeat revascularizations including repeated percutaneous coronary intervention and coronary bypass grafting, cerebrovascular accident and rehospitalizations. This research was supported by a fund by Research of Korea Centers for Disease Control and Prevention.
Results
During the primary PCI, potent antiplatelet agents such as prasugrel and ticagrelor were used in 2342 (38.4%). PCI was performed through transradial approach in 1490 (25.2%). Thrombus aspiration and intravascular ultrasound (IVUS) examination was done in 2204 (36.1%) and 1079 (18.1%), respectively. Glycoprotein IIB-IIIA inhibitor was administered in 1295 (21.7%). Among them, potent antiplatelet agents, transradial intervention, IVUS, and thrombus aspiration significantly reduced MACCEs at 1 year. Glycoprotein IIB-IIIA inhibitor was not effective to improved clinical outcome. In Cox-proportional hazards model, potent antiplatelet agents (hazard ratio 0.82, 95% confidence interval 0.67–0.99; p=0.045) and transradial intervention (hazard ratio 0.61, 95% confidence interval 0.47–0.78; p<0.001) was an independent predictor of MACCEs after adjusting for confounding variables. Combined use of potent antiplatelet agents and transradial intervention (hazard ratio 0.54; 95% confidence interval 0.37–0.80; p=0.002) substantially reduced MACCEs at 1 year.
Conclusion
Among evidence based procedures during the primary PCI, combined use of potent antiplatelet agents and transradial intervention was optimal procedural strategy to improve clinical outcome.

Abstract
Transthyretin familial amyloid polyneuropathy (TTR-FAP) is a life-threatening autosomal dominant disease caused by the deposition of amyloid fibrils composed of TTR proteins. Symptoms of this disease include progressive sensorimotor neuropathy, cardiomyopathy, and involvement of other organs. We described a pediatric case of extremely early onset TTR-FAP with a TTR Leu55Pro mutation. A 17-year-old boy began to suffer from lower limb weakness, gait disturbance, and decreased sensation from 14 years of age onward. He presented with hypertrophic cardiomyopathy, periorbital and scleral ecchymosis, anhidrosis, orthostatic intolerance, and gastrointestinal autonomic dysfunction including nausea, vomiting, and diarrhea alternating with constipation. The patient's older sister had developed similar gastrointestinal symptoms from 20 years of age onward and was diagnosed as having hypertrophic cardiomyopathy. The boy's biopsy results showed infiltrated amyloid deposition on subcutaneous fat tissue and endocardium. Genetic analysis of the TTR gene demonstrated that both the patient and his sister had a pathogenic mutation, c.224T > C (Leu55Pro). Both patients were prescribed tafamidis, a TTR stabilizing agent. Although a majority of TTR-FAPs occur during adulthood, it should be suspected, even in pediatric populations, when symmetric length dependent neuropathy occurs in conjunction with a family history of neuropathy, autonomic neuropathy, and/or cardiomyopathy.

Abstract
Objective: To compare the characteristics of Mycoplasma pneumoniae necrotizing pneumonia (MPNP) and bacterial necrotizing pneumonia (BNP), and explore the biomarkers for differentiation of MPNP from BNP. Methods: A retrospective, observational study of 52 necrotizing pneumonia (NP) cases who were hospitalized in our hospital from January 2008 to December 2017 was conducted. According to the pathogen causing NP, patients were divided into two groups, BNP and MPNP, and the clinical manifestations, laboratory data, imaging findings, hospital course and prognosis between these groups were analyzed. Results: This study enrolled 19 boys and 33 girls, and the median ages of patients were 4.4 (0.1-13.8) years old. Of the totally of 52 NP patients, 19 were in the BNP group (9 boys and 10 girls), 33 were in the MPNP group (10 boys and 23 girls). The mean age of MPNP patients was much older than that of BNP patients (5.2 (2.3-13.2) years vs. 1.8 (0.1-13.8) years, Z=-0.128, P<0.01). The number of patients with tachypnea and pleural effusion septation were significantly higher in BNP patients than those in MPNP patients (15 cases vs. 4 cases, χ(2)=23.222, P<0.01; 14 cases vs. 1 case, χ(2)=29.326, P<0.01), which more needed to oxygentherapy (18 cases vs. 12 cases, χ(2)=16.833, P<0.01) and undergo chest drainage (9 cases vs. 4 cases, χ(2)=5.829, P=0.022); while the number of patients required bronchoalveolar lavage was higher in MPNP patients than that in BNP patients (5 cases vs. 32 cases, χ(2)=29.326, P<0.01). The values of white blood cell (WBC) (23.2 (5.2-67.1)×10(9)/L vs. 9.7 (6.3-18.7)×10(9)/L, Z=-4.855, P<0.01), procalcitonin (PCT) (3.69 (0.23-90.15) mg/L vs. 0.28 (0.02-1.44) mg/L, Z=-3.207, P=0.001), C reactive protein (CRP) (160 (94-220) mg/L vs. 90 (5-134) mg/L, Z=-4.337, P<0.01), interleukin (IL)-10 (11.7 (4.2-401.5) ng/L vs. 4.8 (2.0-23.4) ng/L, Z=-2.278, P=0.023), pleural fluid cell count (5 200 (120-50 000)×10(6)/L vs. 790 (68-6 920)×10(6)/L, Z=-3.125, P=0.002), pleural fluid lactic dehydrogenase (LDH) (3 990 (589-29 382) U/L vs. 2 211 (673-3 993) U/L, Z=-2.488, P=0.013) in BNP group were significantly higher than those in MPNP group; while the values of pleural fluid glucose(0.43 (0.03-18.00) mmol/L vs. 5.95 (4.27-7.87) mmol/L, Z=-2.795, P=0.005), serum tumor necrosis factor (TNF)-α (2.3 (1.0-2.8) ng/L vs. 2.6 (1.3-109.2) ng/L, Z=-2.113, P=0.035) and interferon (IFN)-γ (4.8 (2.6-7.7) ng/L vs. 11.9 (2.9-154.6) ng/L, Z=-2.455, P=0.014) were lower in BNP group than those in MPNP group. Meanwhile, the mean time from the onset of symptoms to the discovery of necrotic lesions was longer in MPNP group than that in BNP group ((20.6±6.4) days vs. (14.6±6.2) days, t=3.029, P=0.004). After treatments, all patients were discharged without death, WBC and PCT recovered more quickly in MPNP group than those in BNP group (12 (0-24) days vs. 0 (0-23) days, Z=-4.484, P<0.01; 10 (5-15) days vs. 0 (0-23) days, Z=-3.244, P=0.001). As to prognosis, 34 cases were followed up, and the results showed that patients recovered without surgical intervention, and chest lesions were resolved within 3.0 (1.0-8.0) months, and the time to necrosis disappearance was similar in the BNP group and MPNP greup (3.0 (1.0-8.0) months vs. 3.0 (1.0-8.0) months, Z=-0.128, P=0.001). In receiver operator characteristic curve analysis, the cut-off values for the age, WBC, CRP, PCT, pleural fluid cell count and pleural fluid glucose were set at 2.4 years of age, 17.2×10(9)/L, 157 mg/L, 1.505 mg/L, 2 630×10(6)/L and 3.73 mmol/L, respectively. Conclusions: NP is found to be severe and prolonged, yet, reversible through proper therapy, such as rational antibiotics application. The age, WBC, CRP, PCT, pleural fluid cell count and pleural fluid glucose could be used as biomarkers to differentiate MPNP from BNP in children.

Abstract
BACKGROUND/AIMS Carbohydrate antigen 125 (CA-125) is an emerging prognostic biomarker for heart failure. We aimed to test the long-term prognostic value of CA-125 in combination with N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with acute decompensated heart failure (ADHF). METHODS This observational study included a total of 413 patients (64.1 ± 15.6 yearold, 214 men) with ADHF. All-cause mortality during the 2-year follow-up was investigated for the prognosis. RESULTS During the follow-up (mean follow-up, 591 ± 233 days), 109 deaths (26.0%) were recorded. In the multivariable analysis model, CA-125 was an independent factor associated with all-cause mortality (log CA-125: hazard ratio, 1.23; 95% confidence interval, 1.02 to 1.48; p = 0.030) together with age, sex, New York Heart Association class, β-blocker, and NT-proBNP. The Kaplan-Meier survival analysis demonstrated that the group with both low marker levels showed the best 2-year survival (87.9%) followed by the group with low NT-proBNP and high CA-125 (76.1%), high NT-proBNP and low CA-125 (64.7%) and high NT-proBNP and high CA-125 levels (54.3%) (p < 0.001). Addition of CA-125 in combination with NT-proBNP and established risk factors further increased the predictive power for mortality in patients with ADHF. CONCLUSION CA-125 was an independent factor associated with all-cause mortality in patients with ADHF. Combination of CA-125 with NT-proBNP significantly improved the prediction of mortality in patients with ADHF.

Abstract
Objective: To investigate the efficacy of bronchoalveolar lavage (BAL) and its influence factors in the treatment of Mycoplasma pneumoniae pneumonia (MPP) with atelectasis. Methods: A retrospective case control study was performed on hospitalized MPP patients with atelectasis and received BAL in the Department of Pulmonology, Children's Hospital Zhejiang University School of Medicine from January 1, 2015 to July 31, 2017. Fever relieved in 48 hours and chest imaging improved in one week after BAL were considered effective. Clinical data, including age, sex, blood routine tests, lactate dehydrogenase (LDH), cytokines, complications, fever duration before BAL, course of disease before BAL, sputum plug, atelectasis area and its CT values of atelectasis site were collected. Student's t test, Mann-Whitney U test, or chi square test were used. Results: (1) A total of 163 patients were enrolled, including 69 boys and 94 girls, with the ratio of 1∶1.36. Their ages ranged from 6 months to 12.6 years. (2) On the day of bronchoscope, 113 patients still had fever. They were divided into effective group (n=66) and ineffective group (n=47) according to whether fever was relieved in 48 hours after BAL. The effective group were found to have less sputum plug compared with the ineffective group (33% (22/66) vs. 57% (27/47), χ(2)=6.499, P=0.011). The other factors such as sex, age, fever duration before BAL, course of disease before BAL, C reactive protein (CRP), LDH, IL-2, IL-4, IL-6, IL-10, TNF, IFN-γ, atelectasis area and CT value showed no significant difference between the two groups (all P>0.05). (3)A total of 122 cases had chest imaging after BAL. According to chest imaging improvement, they were divided into effective group (n=81) and ineffective group (n=41). The effective group showed lower CT value ((58±9) vs. (63±8) HU, t=-2.436, P=0.017), IL-6 and IL-10 (M(Q(1), Q(3))) (21.0 (1.9, 48.4) vs. 36.4(21.8, 93.6), 4.9 (3.7, 9.6) vs. 7.7 (4.4, 12.0) ng/L, Z=-2.387,-2.009, P=0.017, 0.045). Sex, age, fever duration before BAL, course of disease before BAL, CRP, LDH, IL-2, IL-4, TNF, IFN-γ, atelectasis area showed no significant differences between the two groups (all P>0.05). (4) Patients were divided into sputum plug group (57 cases) and non sputum plug group (106 cases) according to bronchoscopic findings. The sputum plug group showed higher LDH, CRP, IL-6, IFN-γ, incidence of pleural effusion and extrapulmonary complications (585(433, 833) vs. 369 (312, 588) U/L, 42 (19, 103) vs. 25 (12, 45) mg/L, 38.8 (22.1, 71.3) vs. 20.7 (9.2, 48.3) ng/L, 33.1 (13.5, 89.3) vs. 12.7 (6.5, 33.6) ng/L, 73.7% (42/57) vs. 52.8% (56/106), 40.4% (23/57) vs. 17.0% (18/106)), with statistically significant differences (Z=-4.865,-3.435,-3.098,-3.704, χ(2)= 0.010, 0.001, all P<0.01) . Additionally, fewer patients showed fever relief within 48 hours after BAL in the cases with sputum plug cases compared those without sputum plug (44.9% (22/49) vs. 68.8% (44/64), χ(2)= 0.011, P=0.009). Fewer patients showed chest imaging improvement within one week after BAL in the cases with sputum plug compared with those without sputum plug, but did not show significant difference (56.5% (26/46) vs. 72.4% (55/76), χ(2)=0.073, P=0.056). Conclusions: BAL has some therapeutic effect on fever or atelectasis in MPP children complicated with atelectasis. Chest imaging improvement or fever relief may be hampered by sputum plug, increased IL-6 or IL-10.

Rationale and Design of the High Platelet Inhibition with Ticagrelor to Improve Left Ventricular Remodeling in Patients with ST-Segment Elevation Myocardial Infarction (HEALING-AMI) Trial. Korean Circ J 2019; 49:586-599. [PMID: 31074220 PMCID: PMC6597457 DOI: 10.4070/kcj.2018.0415] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2018] [Revised: 02/05/2019] [Accepted: 02/20/2019] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Impaired recovery from left ventricular (LV) dysfunction is a major prognostic factor after myocardial infarction (MI). Because P2Y₁₂ receptor blockade inhibits myocardial injury, ticagrelor with off-target properties may have myocardial protection over clopidogrel. In animal models, ticagrelor vs. clopidogrel protects myocardium against reperfusion injury and improves remodeling after MI. We aimed to investigate the effect of ticagrelor on sequential myocardial remodeling process after MI. METHODS High platelet inhibition with ticagrelor to improve LV remodeling in patients with ST-segment elevation MI (HEALING-AMI) is an investigator-initiated, randomized, open-label, assessor-blinded, multi-center trial done at 10 sites in Korea. Patients will be enrolled if they have ST-segment elevation MI (STEMI) treated with primary percutaneous coronary intervention and a planned duration of dual antiplatelet treatment of at least 6 months. Screened patients will be randomly assigned (1:1) using an internet-based randomization with a computer-generated blocking with stratification across study sites to either ticagrelor or clopidogrel treatment. The co-primary primary endpoints are LV remodeling index with three-dimensional echocardiography and the level of N-terminal prohormone B-type natriuretic peptide (NT-proBNP) at 6 months representing post-MI remodeling processes. Changes of LV end-systolic/diastolic volume indices and LV ejection fraction between baseline and 6-month follow-up will be also evaluated. Analysis is per protocol. CONCLUSIONS HEALING-AMI is testing the effect of ticagrelor in reducing adverse LV remodeling following STEMI. Our trial would show the benefit of ticagrelor vs. clopidogrel related to the recovery of post-MI LV dysfunction beyond potent platelet inhibition.
