RESUMO
Background@#Recently, a ring-type cuffless blood pressure (BP) measuring device has been developed. This study was a prospective, single arm, first-in-human pivotal trial to evaluate accuracy of BP measurement by the new device. @*Methods@#The ring-type smart wearable monitoring device measures photoplethysmography signals from the proximal phalanx and transmits the data wirelessly to a connected smartphone. For the BP comparison, a cuff was worn on the arm to check the reference BP by auscultatory method, while the test device was worn on the finger of the opposite arm to measure BP simultaneously. Measurements were repeated for up to three sets each on the left and right arms. The primary outcome measure was mean difference and standard deviation of BP differences between the test device and the reference readings. @*Results@#We obtained 526 sets of systolic BP (SBP) and 513 sets of diastolic BP (DBP) from 89 subjects, with ranges of 80 to 175 mmHg and 43 to 122 mmHg for SBP and DBP, respectively.In sample-wise comparison, the mean difference between the test device and the reference was 0.16 ± 5.90 mmHg (95% limits of agreement [LOA], −11.41, 11.72) in SBP and −0.07 ± 4.68 (95% LOA, −9.26, 9.10) in DBP. The test device showed a strong correlation with the reference for SBP (r = 0.94, P < 0.001) and DBP (r = 0.95, P < 0.001). There were consistent results in subject-wise comparison. @*Conclusion@#The new ring-type BP measuring device showed a good correlation for SBP and DBP with minimal bias compared with an auscultatory method.
RESUMO
Background@#Few studies have examined the incidence of chronic kidney disease (CKD) and metabolic syndrome (MS) and their combined prognostic effects in adult congenital heart disease (ACHD). Our aims were to identify the incidence and prognostic implications of CKD and MS in ACHD. @*Methods@#This is retrospective cohort study. We included 2,462 ACHD ≥ 20 years of age who were treated at a tertiary hospital in Korea from 2006 to 2018. CKD was defined as an estimated glomerular filtration rate < 60 mL/min/1.73m 2 . MS was diagnosed based on the presence of abnormal metabolic parameters: blood sugar level, obesity, dyslipidemia, and hypertension. The primary outcome was all-cause mortality from 2006 through 2019 using data from the Ministry of the Interior and Safety in Korea. @*Results@#The incidence of CKD and MS in ACHD was 7.6% and 35.9%, respectively. The coexistence rate of CKD and MS was 4.6%. Although MS was not independently associated with mortality in the multiple analysis (adjusted hazard ratio [aHR], 1.07; 95% confidence interval [CI], 0.79–1.46), it was closely related to the presence of CKD (adjusted odds ratio, 2.62; 95% CI, 1.89–3.63). ACHD patients with CKD had a significantly increased risk of mortality compared with those without CKD (aHR, 2.84; 95% CI, 2.00–4.04). @*Conclusions@#In patients with ACHD, the distribution of MS is higher, and both MS and its components were associated with CKD. Given the CKD was independently associated with mortality, close monitoring and management of renal dysfunction and metabolic parameters in ACHD patients is needed.
RESUMO
Background and Objectives@#Several cases involving severe right ventricular (RV) failure in advanced cancer patients have been found to be pulmonary tumor thrombotic microangiopathies (PTTMs). This study aimed to discover the nature of rapid RV failure syndrome with a suspected diagnosis of PTTM for better diagnosis, treatment, and prognosis prediction in clinical practice. @*Methods@#From 2011 to 2021, all patients with clinically suspected PTTM were derived from the one tertiary cancer hospital with more than 2000 in-hospital bed. @*Results@#A total of 28 cases of clinically suspected PTTM with one biopsy confirmed case were included. The most common cancer types were breast (9/28, 32%) and the most common tissue type was adenocarcinoma (22/26, 85%). The time interval from dyspnea New York Heart Association (NYHA) Grade 2, 3, 4 to death, thrombocytopenia to death, desaturation to death, admission to death, RV failure to death, cardiogenic shock to death were 33.5 days, 14.5 days, 7.4 days, 6.4 days, 6.1 days, 6.0 days, 3.8 days and 1.2 days, respectively. The NYHA Grade 4 to death time was 7 days longer in those who received chemotherapy (7.1 days vs.13.8 days, p value=0.030). However, anticoagulation, vasopressors or intensive care could not change clinical course. @*Conclusions@#Rapid RV failure syndrome with a suspected diagnosis of PTTM showed a rapid progressive course from symptom onset to death. Although chemotherapy was effective, increased life survival was negligible, and treatments other than chemotherapy did not help to improve the patient’s prognosis.
RESUMO
Background@#Reduced exercise capacity reflects symptom severity and clinical outcomes in patients with hypertrophic cardiomyopathy (HCM). The present study aimed to identify factors that may affect exercise capacity in patients with HCM. @*Methods@#In 294 patients with HCM and preserved left ventricular (LV) ejection fraction, we compared peak oxygen consumption (peak VO2 ) evaluated by cardiopulmonary exercise testing as a representative parameter of exercise tolerance with clinical and laboratory data, including N-terminal pro-hormone of brain natriuretic peptide (NT-proBNP), diastolic parameters on echocardiography, and the grade of myocardial fibrosis on cardiac magnetic resonance imaging (CMR). @*Results@#Median peak VO2 , was 29.0 mL/kg/min (interquartile range [IQR], 25.0–34.0). Age (estimated β = −0.140, P < 0.001), female sex (β = −5.362, P < 0.001), NT-proBNP (β = −1.256, P < 0.001), and E/e′ ratio on echocardiography (β = −0.209, P = 0.019) were significantly associated with exercise capacity. Peak VO2 was not associated with the amount of myocardial fibrosis on CMR (mean of late gadolinium enhancement 12.25 ± 9.67%LV). @*Conclusion@#Decreased exercise capacity was associated with age, female sex, increased NTproBNP level, and E/e′ ratio on echocardiography. Hemodynamic changes and increased filling pressure on echocardiography should be monitored in this population for improved outcomes.
RESUMO
Background@#Few studies used nationwide data to assess the survival rates (SRs) and death risk for idiopathic pulmonary arterial hypertension (IPAH; ICD-10 I27.0) in Korea. @*Methods@#IPAH data (N = 9,017; female:male = 6:4) were collected from the National Health Insurance Service in Korea, from 2006 through 2017. The data consisted of primary diagnoses related to IPAH. The Kaplan–Meier method and Cox proportional-hazards analyses were carried out. @*Results@#The mean age was 62.3 (± 19.4) years, 64.2 (± 18.9) years in female and 59.4 (± 19.8) years in male (P < 0.001). The one-, three-, five- and 10-year SRs for IPAH were 89.0%, 79.8%, 72.3% and 57.0%, respectively. The adjusted hazard ratio (HR) of IPAH was 1.81 (95% confidence interval [CI], 1.26–2.59) in 60–69 age group, 3.42 (95% CI, 2.40–4.87) in 70–79, and 7.73 (95% CI, 5.43–11.0) in 80s. Other risk factors were male, low-income status, diabetes, myocardial infarction, atrial fibrillation, ischemic stroke, hemorrhagic stroke, and malignant neoplasm. @*Conclusion@#The 10-year SR of IPAH was 57% in Korea. The HR for IPAH was significantly high in patients with older age and other risk factors.
RESUMO
Hypertrophic cardiomyopathy (HCM) is one of the most common inheritable cardiomyopathies. Contemporary management strategies, including the advent of implantable cardioverter-defibrillators and effective anticoagulation, have substantially improved the clinical course of HCM patients; however, the disease burden of HCM is still high in Korea. Sudden cardiac death (SCD), atrial fibrillation and thromboembolic risk, dynamic left ventricular outflow tract (LVOT) obstruction, and heart failure (HF) progression remain important issues in HCM. SCD in HCM can be effectively prevented with implantable cardioverter-defibrillators. However, appropriate patient selection is important for primary prevention, and the 5-year SCD risk score and the presence of major SCD risk factors should be considered. Anticoagulation should be initiated in all HCM patients with atrial fibrillation regardless of the CHA 2 DS 2 -VASc score, and non-vitamin K antagonist oral anticoagulants are the first option. Symptomatic dynamic LVOT obstruction is first treated medically with negative inotropes, and if symptoms persist, septal reduction therapy is considered. The recently approved myosin inhibitor mavacamten is promising. HF in HCM is usually related to diastolic dysfunction, while about 5% of HCM patients show reduced left ventricular ejection fraction <50%, also referred to as “end-stage” HCM. Myocardial fibrosis plays an important role in the progression to advanced HF in patients with HCM. Patients who do not respond to guideline-directed medical therapy can be considered for heart transplantation. The development of imaging techniques, such as myocardial deformation on echocardiography and late gadolinium enhancement on cardiac magnetic resonance, can provide better risk evaluation and decision-making for management strategies in HCM.
RESUMO
Background@#The number of adults with congenital heart disease (ACHD) with atrial fibrillation (AF) is expected to increase. We sought to assess the impact of AF on survival in Korean ACHD. @*Methods@#Records of AF in ACHD were extracted from the records of the Korea National Health Insurance Service from 2006 through 2015. Multiple Cox proportional hazards analyses were carried out after adjustment for age, sex, income level, AF, and comorbidities.Survival rates (SRs) with and without AF were compared. The death records from 2006 through 2016 were included. @*Results@#A total of 3,999 ACHD had AF (51.4% were male) and 62,691 ACHD did not have AF (43.5% were male); the proportion of ACHD who were 60 years and older was 53.0% and 27.0% in those with and without AF, respectively (P < 0.001). The age-standardized incidence rate for AF was 1,842.0 persons per 100,000 people in the Korean general population from 2006 through 2015. For AF in ACHD, it was 5,996.4 persons per 100,000 ACHD during the same period, which was higher than that in the general population (P< 0.001). Significantly higher proportion of death (20.9%) occurred in ACHD with AF than without AF (8.3%) (P< 0.001). The adjusted hazard ratio for AF of death in ACHD was 1.39 (95% confidence interval, 1.29– 1.50). The ten-year SR of ACHD with AF was 69.7% whereas it was 87.5% in non-AF (P < 0.001). @*Conclusion@#In ACHD, AF occurs more frequently and has a worse prognosis than seen in the non-valvular general population in Korea. AF is associated with increased death in ACHD, especially with aging.
RESUMO
Objective@#The clinical course of an individual patient with heart failure is unpredictable with left ventricle ejection fraction (LVEF) only. We aimed to evaluate the prognostic value of cardiac magnetic resonance (CMR)-derived myocardial fibrosis extent and to determine the cutoff value for event-free survival in patients with non-ischemic cardiomyopathy (NICM) who had severely reduced LVEF. @*Materials and Methods@#Our prospective cohort study included 78 NICM patients with significantly reduced LV systolic function (LVEF < 35%). CMR images were analyzed for the presence and extent of late gadolinium enhancement (LGE). The primary outcome was major adverse cardiac events (MACEs), defined as a composite of cardiac death, heart transplantation, implantable cardioverter-defibrillator discharge for major arrhythmia, and hospitalization for congestive heart failure within 5 years after enrollment. @*Results@#A total of 80.8% (n = 63) of enrolled patients had LGE, with the median LVEF of 25.4% (19.8–32.4%). The extent of myocardial scarring was significantly higher in patients who experienced MACE than in those without any cardiac events (22.0 [5.5–46.1] %LV vs. 6.7 [0–17.1] %LV, respectively, p = 0.008). During follow-up, 51.4% of patients with LGE ≥ 12.0 %LV experienced MACE, along with 20.9% of those with LGE ≤ 12.0 %LV (log-rank p = 0.001). According to multivariate analysis, LGE extent more than 12.0 %LV was independently associated with MACE (adjusted hazard ratio, 6.71; 95% confidence interval, 2.54–17.74; p < 0.001). @*Conclusion@#In NICM patients with significantly reduced LV systolic function, the extent of LGE is a strong predictor for longterm adverse cardiac outcomes. Event-free survival was well discriminated with an LGE cutoff value of 12.0 %LV in these patients.

RESUMO
Background/Aims@#Although acute pulmonary embolism (PE) adversely impacts survival and should be treated regardless of cancer, the treatment rate of cancer-related PE is relatively low. We aimed to compare clinical characteristics and long term prognosis of PE in patients with or without cancer. @*Methods@#From March 2010 to December 2013, patients with newly diagnosed PE were analyzed. Baseline demographics, comorbidities, cancer status and clinical manifestations of PE were recorded. We defined primary composite outcome as recurrent venous thromboembolism (VTE) and death from PE. @*Results@#Among a total of 976 patients with PE, the 703 (72.0%) had cancer-related PE. Cancer-related PE group was more frequently asymptomatic (54.5% vs. 13.2%, p < 0.001), less extensive (involvement of bilateral pulmonary arteries: 42.8% vs. 51.3%, p = 0.017; lung infarction: 5.3% vs. 10.3%, p = 0.005) and less likely to accompany right ventricular dysfunction (10.3% vs. 27.2%, p < 0.001) compared with the non-cancer PE group. Anticoagulation was less frequently underwent in patients with cancer-related PE than those without cancer (62.0% vs. 81.7%, p < 0.001). A composite of recurrent VTE and death from PE was significantly higher in the cancer-related PE group (14.4% vs. 6.6%, p = 0.001). @*Conclusions@#Although PE in cancer patients were seem to be less aggressive initially, compared to those without cancer, they had significantly poor prognosis. Given a high rate of recurrent VTE and relatively similar risk of anticoagulation associated bleeding events in cancer patients, more active treatment of PE is warranted in cancer patients.
RESUMO
Background and Objectives@#In East Asia, tuberculous pericarditis still occurs in immunocompetent patients. We aimed to investigate clinical course of tuberculous pericarditis and the trends of echocardiographic parameters for constrictive pericarditis. @*Methods@#We retrospectively analyzed medical records of patients with tuberculous pericarditis between January 2010 and January 2017 in Samsung Medical Center. Treatment consists of the standard 4-drug anti-tuberculosis regimen for 6 months with or without corticosteroids. We performed echocardiography at initial diagnosis, 1, 3 and 6 months later. @*Results@#Total 50 cases with tuberculous pericarditis in immunocompetent patients were enrolled. Echocardiographic finding at initial diagnosis divided into 3 groups: 1) pericardial effusion only (n=28, 56.0%), 2) effusive constrictive pericarditis (n=10, 20.0%) and 3) constrictive pericarditis (n=12, 24.0%). The proportion of patients with constrictive pericarditis decreased gradually over time. After 6 months, only 5 patients still had constrictive pericarditis. Out of the 28 patients who initially presented with effusion alone, only one patient developed constrictive pericarditis. Echocardiographic parameters representing constrictive pericarditis gradually disappeared over the follow up period. Ventricular interdependency improved significantly from 1 month follow-up, whereas septal bounce and pericardial thickening were still observed after 6 months without significant constrictive physiology. @*Conclusions@#Tuberculous pericarditis with pericardial effusion without constrictive physiology is unlikely to develop into constrictive pericarditis in immunocompetent hosts, if treated with optimal anti-tuberculous medication and steroid therapy. Even though there were hemodynamic feature of constrictive pericarditis, more than 80% of the patients were improved from constrictive pericarditis.
RESUMO
Partial anomalous pulmonary venous return (PAPVR) is a rare congenital cardiac anomaly that can be difficult to detect and often remains undiagnosed. PAPVR is diagnosed using non-invasive imaging techniques such as echocardiography, CT, and MRI. Image data are reviewed on a 2-dimensional (D) monitor, which may not facilitate a good understanding of the complex 3D heart structure. In recent years, 3D printing technology, which allows the creation of physical cardiac models using source image datasets obtained from cardiac CT or MRI, has been increasingly used in the medical field. We report a case involving a 3D-printed model of PAPVR with a biatrial connection. This model demonstrated separate drainages of the right upper and middle pulmonary veins into the lower superior vena cava (SVC) and the junction between the SVC and the right atrium, respectively, with biatrial communication through the right middle pulmonary vein.

RESUMO
BACKGROUND AND OBJECTIVES: Udenafil, a new phosphodiesterase-5 inhibitor (PDE5i), has been used to treat erectile dysfunction. Given the proven benefit of PDE5i in pulmonary arterial hypertension (PAH), we evaluated serial hemodynamic changes after single udenafil administration to determine the appropriate therapeutic dose. METHODS: Eighteen patients were randomly allocated into one of 3 groups: placebo, udenafil 50 mg (U50), and udenafil 100 mg (U100). Diagnosis for inclusion was idiopathic PAH or PAH associated with connective tissue disease. Patients with any contraindication to PDE5i, and/or PDE5i treatment in the past 1 month were excluded. Continuous hemodynamic monitoring was performed by placing a Swan-Ganz catheter. Information on cardiac index (CI), mean pulmonary arterial pressure (mPAP), mean systemic arterial pressure (mSAP), pulmonary arterial wedge pressure (PAWP), and pulmonary vascular resistance index (PVRI) was obtained for 4 hours after drug administration. RESULTS: The mPAP significantly decreased in both the U50 and U100 (−11 mmHg and −8 mmHg from baseline, respectively, p < 0.1). The mSAP also decreased in both U50 and U100; however, the decrease was greater in the U100 (Δ=−8.5 mmHg and Δ=−14.0 mmHg). CI increased in the U50, but decreased in the U100. Although PVRI decreased in both, statistical significance was only achieved in the U50 compared to placebo. PAWP was stable during monitoring. U50 had at least 4 hour-effect after administration. Only 2 patients with U100 experienced mild adverse events. CONCLUSIONS: This is the first demonstration of the acute hemodynamic changes induced by udenafil. U50 is considered an optimal dose for treating PAH with more than 4-hour treatment effect. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01553721.

OBJECTIVES: To report our experiences in pregnant patients with pulmonary arterial hypertension (PAH) who were treated with targeted therapy. METHODS: From 2011 to 2017, women who decided to maintain pregnancies in our PAH clinic were included. Clinical data, management, and outcomes of the mothers and fetuses were reviewed. RESULTS: Nine women with PAH and 10 deliveries were reviewed. The median maternal age was 28 (26–32) years old. The functional status of each patient was New York Heart Association functional class II or III at first visit. Sildenafil was prescribed in advance in 9 cases of delivery. Multidiscipline team approach management and intensive care were performed during the peripartum period. There was no maternal or fetal mortality. Severe cardiac events occurred in 2 patients with Eisenmenger syndrome: cardiac arrest and uncontrolled arrhythmia. Non-cardiac events occurred in 3 cases: postpartum bleeding, urinary tract infection, and pneumonia. The median gestational period at delivery was about 34 (32–38) weeks. Three cases were emergent delivery because of unexpected preterm labor. Intrauterine growth restriction developed in 4 fetuses. CONCLUSIONS: Pregnancy could be maintained by the introduction of targeted therapy rather more safely than the previous era in the case of maintenance of pregnancy. Intensive care and a multidisciplinary team approach can possibly improve the outcomes of the pregnant women with PAH and their babies. However, pregnancy in patients with PAH is still strongly prohibited and it can be tried in expert center where there has sufficient multidisciplinary team approach in case of inevitability.

RESUMO
PURPOSE: While concerns regarding trastuzumab-related cardiac dysfunction (TRCD) in patients with breast cancer are increasing, there is a lack of evidence supporting the current recommendations for TRCD monitoring. We aimed to investigate the clinical predictors of TRCD in the adjuvant setting of human epidermal growth factor receptor 2–positive breast cancer patients. MATERIALS AND METHODS: From August 2003 to April 2016, consecutive 998 patients who were treated with adjuvant trastuzumab for breast cancer were retrospectively evaluated. TRCD was defined as a decrease ≥10% in left ventricular ejection fraction (LVEF), with a decline below the normal limit or symptomatic heart failure. RESULTS: Among 787 eligible patients who had complete data sets consisting of both baseline and follow-up assessment of left ventricular systolic function by echocardiography (mean age, 49.9±9.5 years), 58 (7.4%) developed TRCD. TRCD patients had lower baseline LVEF (63% [59–66] vs. 65% [61–68], p=0.016) and more frequently administered Adriamycin (98% vs. 89%, p=0.022) than those without TRCD. On follow-up echocardiography, a drop in LVEF ≥5% within the first 3 months was more frequent in TRCD patients (78.3% vs. 38.4%, p<0.001). Regardless of baseline LVEF and Adriamycin treatment, a drop in LVEF ≥5% within the first 3 months of trastuzumab administration was strongly associated with the development of TRCD (adjusted hazard ratio, 45.1[17.0–127.6], p<0.001). CONCLUSION: The overall incidence of TRCD was 7.4% in Asian breast cancer patients treated with adjuvant trastuzumab. A decline in LVEF ≥5% within the first 3 months of trastuzumab initiation was strongly associated with TRCD development in patients with breast cancer.

BACKGROUND/AIMS@#The aim of our study was to compare the characteristics of nosocomial infective endocarditis (NIE) with community-acquired infective endocarditis (CIE) and to determine independent risk factors for in-hospital death.@*METHODS@#We retrospectively reviewed the medical records of 560 patients diagnosed with infective endocarditis. NIE was defined by a diagnosis made > 72 hours after hospital admission or within 2 months of hospital discharge.@*RESULTS@#Among the 560 cases reviewed, 121 were classified as NIE. Compared with patients with CIE, patients with NIE were older (mean ± SD, 51.30±18.01 vs. 59.76±14.87, p < 0.001). The in-hospital death rate of the NIE group was much higher than that of the CIE group (27.3% vs. 5.9%, p < 0.001). More patients with NIE had central intravenous catheters, and were undergoing hemodialysis (p < 0.001). Methicillin-resistant Staphylococcus aureus (MRSA) was the most common causal microorganism of NIE, and MRSA (p < 0.001) and fungus (p = 0.002) were more common in NIE compared with CIE. On multiple analysis, age, liver cirrhosis, cancer chemotherapy, central intravenous catheter, hemodialysis, and genitourinary tract manipulation were independent clinical risk factors for NIE. Among the patients with NIE, 33 died during their hospital admission. The independent risk factors for in-hospital death were older age (adjusted odds ratio [OR], 1.04; 95% confidence interval [CI], 1.01 to 1.07; p = 0.037) and chemotherapy for malignancy (adjusted OR, 3.89; 95% CI, 1.18 to 12.87; p = 0.026).@*CONCLUSIONS@#Because of the considerable incidence of NIE and its poor prognosis, we should pay attention to early diagnosis and active management of NIE, especially for older patients and patients receiving chemotherapy.
RESUMO
BACKGROUND: The treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH) is pulmonary endarterectomy (PEA). However, not all patients are eligible for PEA, and some patients experience recurrence of pulmonary hypertension even after PEA. METHODS: Patients who underwent balloon pulmonary angioplasty (BPA) between December 2015 and April 2017 were enrolled from the Samsung Medical Center CTEPH registry. Enrolled patients underwent right heart catheterization, echocardiography, and 6-minute walk distance (6MWD) at baseline, 4 and 24 weeks after their first BPA session. We compared clinical and hemodynamic parameters at the baseline and last BPA session. RESULTS: Fifty-two BPA sessions were performed in 15 patients, six of whom had a history of PEA. BPA resulted in improvements in World Health Organization (WHO) functional class (2.9 ± 0.8 to 1.7 ± 0.6, P = 0.002), 6MWD (387.0 ± 86.4 to 453.4 ± 64.8 m, P = 0.01), tricuspid annular plane systolic excursion (14.1 ± 3.6 to 15.6 ± 4.3 mm, P = 0.03) and hemodynamics, including a decline in mean pulmonary artery pressure (41.1 ± 13.1 to 32.1 ± 9.5 mmHg, P < 0.001) and in pulmonary vascular resistance (607.4 ± 452.3 to 406.7 ± 265.4 dyne.sec.cm−5, P = 0.01) but not in cardiac index (2.94 ± 0.79 to 2.96 ± 0.93 L/min/m2, P = 0.92). Six cases of complications were recorded, including two cases of reperfusion injury. CONCLUSION: BPA might be a safe and effective treatment strategy for both inoperable CTEPH patients and patients with residual pulmonary hypertension after PEA.
