Prognostic value of weight loss in hospitalized patients with heart failure.

BACKGROUND: Weight loss is a poor prognostic factor in patients with chronic heart failure (HF). However, whether the same is true for hospitalized patients with HF is unknown, even though hospitalization is the first opportunity for many patients to be diagnosed with HF. This study aimed to investigate the prognostic value of weight loss in patients hospitalized for HF. METHODS: This was a post-hoc analysis of the FRAGILE-HF study, a prospective multi-center, observational study including 1,332 hospitalized older (≥65 years) patients with HF. The primary outcome was all-cause death within two years of discharge. RESULTS: Self-reported body weight data one year prior to hospital admission were available for 1,106 patients (83.0%) and were compared with their weight after decongestion therapy. The median weight change was -6.9% [-2.4 - -11.9] and 86.8% of the overall cohort experienced some weight loss. Whereas patients with weight loss ≥ 5%, which is a well-validated cut-off in chronic HF, had comparable mortality to those with less weight loss (p = 0.96 by log-rank test), patients with weight loss > 12%, the lowest quartile value, had higher mortality than those with less weight loss (p = 0.024 for all-cause mortality, p = 0.028 for non-cardiovascular mortality, and p = 0.28 for cardiovascular mortality, respectively). In a Cox proportional hazard model, > 12% weight loss was associated with high mortality after adjusting for known prognostic factors and history of malignancy (adjusted hazard ratio: 1.485 [1.070-2.062], p=0.018). CONCLUSION: Weight loss derived from patient-reported body weight one year before hospitalization was significantly associated with increased mortality after discharge, mainly due to non-cardiovascular etiology, in elderly patients hospitalized for HF.

Prognostic impact of cachexia by multi-assessment in older adults with heart failure: FRAGILE-HF cohort study.

BACKGROUND: Cachexia substantially impacts the prognosis of patients with heart failure (HF); however, there is no standard method for cachexia diagnosis. This study aimed to investigate the association of Evans's criteria, consisting of multiple assessments, with the prognosis of HF in older adults. METHODS: This study is a secondary analysis of the data from the FRAGILE-HF study, a prospective multicentre cohort study that enrolled consecutive hospitalized patients aged ≥65 years with HF. Patients were divided into two groups: the cachexia and non-cachexia groups. Cachexia was defined according to Evans's criteria by assessing weight loss, muscle weakness, fatigue, anorexia, a decreased fat-free mass index and an abnormal biochemical profile. The primary outcome was all-cause mortality, as assessed in the survival analysis. RESULTS: Cachexia was present in 35.5% of the 1306 enrolled patients (median age [inter-quartile range], 81 [74-86] years; 57.0% male); 59.6%, 73.2%, 15.6%, 71.0%, 44.9% and 64.6% had weight loss, decreased muscle strength, a low fat-free mass index, abnormal biochemistry, anorexia and fatigue, respectively. All-cause mortality occurred in 270 patients (21.0%) over 2 years. The cachexia group (hazard ratio [HR], 1.494; 95% confidence interval [CI], 1.173-1.903; P = 0.001) had a higher mortality risk than the non-cachexia group after adjusting for the severity of HF. Cardiovascular and non-cardiovascular deaths occurred in 148 (11.3%) and 122 patients (9.3%), respectively. The adjusted HRs for cachexia in cardiovascular mortality and non-cardiovascular mortality were 1.456 (95% CI, 1.048-2.023; P = 0.025) and 1.561 (95% CI, 1.086-2.243; P = 0.017), respectively. Among the cachexia diagnostic criteria, decreased muscle strength (HR, 1.514; 95% CI, 1.095-2.093; P = 0.012) and low fat-free mass index (HR, 1.424; 95% CI, 1.052-1.926; P = 0.022) were significantly associated with high all-cause mortality, but there was no significant association between weight loss alone (HR, 1.147; 95% CI, 0.895-1.471; P = 0.277) and all-cause mortality. CONCLUSIONS: Cachexia evaluated by multi-assessment was present in one third of older adults with HF and was associated with a worse prognosis. A multimodal assessment of cachexia may be helpful for risk stratification in older patients with HF.

Prevalence and prognostic impact of the coexistence of cachexia and sarcopenia in older patients with heart failure.

BACKGROUND: No study with an adequate patients' number has examined the relationship/overlap between sarcopenia and cachexia. We examined the prevalence of the overlap and prognostic implications of sarcopenia and cachexia in older patients with heart failure using well-accepted definitions. METHODS: This was a post-hoc sub-analysis of the FRAGILE-HF study, a prospective, multicenter, observational study conducted at 15 hospitals in Japan. In total, 905 hospitalized older patients were classified into four groups based on the presence or absence of cachexia and/or sarcopenia, which were defined according to the Evans and Asian Working Group for Sarcopenia criteria revised in 2019, respectively. The primary endpoint was 2-year all-cause mortality. RESULTS: Cachexia and sarcopenia prevalence rates were 32.7% and 22.7%, respectively. Patients were classified into the non-cachexia/non-sarcopenia (55.7%), cachexia/non-sarcopenia (21.7%), non-cachexia/sarcopenia (11.6%), and cachexia/sarcopenia (11.0%) groups. During the 2-year follow-up period after discharge, 158 (17.5%) all-cause deaths (124 cardiovascular deaths [CVD] and 34 non-CVD) were observed. The cachexia/sarcopenia group had the lowest body fat mass and exhibited significantly higher mortality rates (log-rank P < 0.001). Cox proportional hazard analysis revealed that cachexia/sarcopenia was an independent prognostic factor after adjusting for known prognostic factors (versus non-cachexia/non-sarcopenia: hazard ratio, 2.78; 95% confidence interval, 1.80-4.29; P < 0.001). Neither cachexia/non-sarcopenia nor non-cachexia/sarcopenia were significantly associated with all-cause mortality compared with non-cachexia/non-sarcopenia. CONCLUSIONS: Cachexia and sarcopenia are prevalent among older hospitalized patients with heart failure; nonetheless, the overlap is not as prominent as previously expected. The presence of cachexia and sarcopenia is a risk factor for all-cause mortality.

Impact of statins in patients with vasospastic angina: A multicenter registry study of the Japanese Coronary Spasm Association.

BACKGROUND: Statins are generally used for patients with coronary artery disease. However, the impact of statins in patients with vasospastic angina (VSA) is not fully understood. METHODS: In a multicenter registry study of the Japanese Coronary Spasm Association (n = 1429), patients with or without statins were compared. The primary endpoint was major adverse cardiac events (MACEs), defined as cardiac death, non-fatal myocardial infarction, unstable angina, heart failure, and appropriate implantable cardioverter defibrillator shock. Propensity score matching and a multivariable Cox proportional hazard model were used to adjust for selection bias in treatment and potential confounding factors. RESULTS: In the whole population, 469 patients received statins, while 960 patients did not receive statins. Patients with statins had a greater prevalence of comorbidities, including hypertension, diabetes, dyslipidemia, and smoking, in comparison to those without statins. The prevalence rates of previous myocardial infarction, significant organic stenosis, and medication use (including calcium channel blockers, angiotensin-converting enzyme inhibitor/angiotensin receptor blockers, and beta blockers) were greater in patients with statins than in those without statins. After propensity matching (n = 211 for both groups), a Kaplan-Meier curve analysis revealed that the incidence of MACE was comparable between patients with and without statins (p = 0.686). MACEs occurred in 6.0% of patients with statins and in 5.9% of those without statins (p = 0.98). CONCLUSION: In this multicenter registry study, statin therapy did not reduce clinical events in VSA patients.

Inaccurate recognition of own comorbidities is associated with poor prognosis in elderly patients with heart failure.

AIMS: A patient's understanding of his or her own comorbidities is part of the recommended patient education for those with heart failure. The accuracy of patients' understanding of their comorbidities and its prognostic impact have not been reported. METHODS AND RESULTS: Patients hospitalized for heart failure (n = 1234) aged ≥65 years (mean age: 80.1 ± 7.7 years; 531 females) completed a questionnaire regarding their diagnoses of diabetes, malignancy, stroke, hypertension, chronic obstructive pulmonary disease (COPD), and coronary artery disease (CAD). The patients were categorized into three groups based on the number of agreements between self-reported comorbidities and provider-reported comorbidities: low (1-2, n = 19); fair (3-4, n = 376); and high (5-6, n = 839) agreement groups. The primary outcome was a composite of all-cause mortality or heart failure rehospitalization at 1 year. The low agreement group had more comorbidities and a higher prevalence of a history of heart failure. The agreement was good for diabetes (κ = 0.73), moderate for malignancy (κ = 0.56) and stroke (κ = 0.50), and poor-to-fair for hypertension (κ = 0.33), COPD (κ = 0.25), and CAD (κ = 0.30). The fair and low agreement groups had poorer outcomes than the good agreement group [fair agreement group: hazard ratio (HR): 1.25; 95% confidence interval (CI): 1.01-1.56; P = 0.041; low agreement group: HR: 2.74: 95% CI: 1.40-5.35; P = 0.003]. CONCLUSIONS: The ability to recognize their own comorbidities among older patients with heart failure was low. Patients with less accurate recognition of their comorbidities may be at higher risk for a composite of all-cause mortality or heart failure rehospitalization.

Comparison of Clinical Characteristics of Acute Myocardial Infarction Between Young (< 55 Years) and Older (55 to < 70 Years) Patients.

Although the incidence of acute myocardial infarction (AMI) has been decreasing in the elderly, it has been increasing in the young, especially in Japan. A social impact of AMI would be greater in the young, because loss of the young directly influences social activities such as business, child-raising, and tax payment. The aim of this study was to identify the specific characteristics of young AMI patients. We retrospectively included 408 consecutive AMI patients < 70 years of age, divided into a young group (< 55 years: n = 136) and an older group (55 to < 70 years: n = 272). The prevalence of overweight was greater in the young group (58.5%) than in the older group (40.7%) (P = 0.001). The frequency of current smokers was higher in the young group (67.6%) than in the older group (44.9%) (P < 0.001). Although the prevalence of hypertension was lower in the young group (66.7%) than in the older group (77.2%) (P = 0.017), that of untreated hypertension was greater in the young group (40.4%) than in the older group (27.2%) (P = 0.007). Furthermore, the prevalence of untreated dyslipidemia was greater in the young group (45.0%) than in the older group (26.6%) (P < 0.001). In conclusion, the young AMI patients had more modifiable risk factors such as obesity, smoking, untreated hypertension, and untreated dyslipidemia than the older patients. There is an unmet medical need for the prevention of AMI in the young generation.

Determinants of Greater Peak radiation skin dose in percutaneous coronary intervention for chronic total occlusion.

BACKGROUND: Peak skin dose (PSD) is closely associated with skin radiation injuries such as skin ulcers in percutaneous coronary intervention (PCI). Although PSD is greater in PCI for chronic total occlusion (CTO) lesions as compared with non-CTO lesions, the determinants of PSD in CTO-PCI are not fully understood. The purpose of this study was to investigate the clinical factors associated with excess PSD in PCI for CTO. METHODS: The study population included a total of 220 CTO-PCI cases that were divided into a standard PSD group (<2 Gy, n = 187) and an excess PSD group (≥2 Gy, n = 33). Clinical, lesion, and procedural characters were compared between the 2 groups. Multivariate logistic regression was performed to investigate the clinical factors associated with excess PSD. RESULTS: Body surface area (BSA) was significantly higher in the excess PSD group (1.85 ± 0.24 m2) than the standard PSD group (1.71 ± 0.18 m2) (p = 0.001). The J-CTO score was significantly higher in the excess PSD group (2.51 ± 1.28) than the standard PSD group (1.60 ± 1.13) (p < 0.001). Multivariate logistic regression analysis revealed that BSA (0.1 mm increase: OR 1.663, 95% CI 1.300-2.128, p < 0.001) and J-CTO score (1-point increase: OR 2.015, 95% CI 1.322-3.071, p = 0.001) were significantly associated with excess PSD. CONCLUSIONS: A large BSA and high J-CTO score were significantly associated with excess PSD. It is important to pay special attention to CTO patients who have a large BSA and/or high J-CTO score to reduce patient's PSD.

Active Participation in Outpatient Cardiac Rehabilitation Is Associated With Better Prognosis After Coronary Artery Bypass Graft Surgery　- J-REHAB CABG Study.

BACKGROUND: There is little evidence regarding the effect of outpatient cardiac rehabilitation (CR) on exercise capacity or the long-term prognosis in patients after coronary artery bypass graft surgery (CABG). This study aimed to determine whether participation in outpatient CR improves exercise capacity and long-term prognosis in post-CABG Japanese patients in a multicenter cohort.Methods and Results:We enrolled 346 post-CABG patients who underwent cardiopulmonary exercise testing during early (2-3 weeks) and late (3-6 months) time points after surgery. They formed the Active (n=240) and Non-Active (n=106) CR participation groups and were followed for 3.5 years. Primary endpoint was a major adverse cardiac event (MACE): all-cause death or rehospitalization for acute myocardial infarction/unstable angina/worsening heart failure. Peak oxygen uptake at 3-5 months from baseline was significantly more increased in Active than in Non-Active patients (+26±24% vs. +19±20%, respectively; P<0.05), and the MACE rate was significantly lower in Active than Non-Active patients (3.4% vs. 10.5%, respectively; P=0.02). Multivariate Cox proportional hazard analysis showed that participation in outpatient CR was a significant prognostic determinant of MACE (P=0.03). CONCLUSIONS: This unique study showed that a multicenter cohort of patients who underwent CABG and actively participated in outpatient CR exhibited greater improvement in exercise capacity and better survival without cardiovascular events than their counterparts who did not participate.

Coronary vasospasm induced by cisplatin for seminoma.

Vascular toxicity is one of serious complications following cisplatin-based chemotherapy. This case suggests that cisplatin has a potential risk of delayed occurrence of vasospastic angina. It is important to perform careful history taking including discontinued drugs for differential diagnosis of chest pain.

Association of less-contrast media with clinical factors in elective percutaneous coronary intervention.

Since the amount of contrast media during percutaneous coronary intervention (PCI) is closely related to the exacerbation of renal function, it should be important to reduce the dose of contrast media during PCI. The purpose of this retrospective study was to evaluate the association of less-contrast media with clinical factors in elective PCI. A total of 709 patients were divided into the less-contrast media group (n = 142) and the conventional-contrast media group (n = 567) according to the quintile of total contrast volume. Univariate and multivariate logistic regression analyses were performed to find associations between the clinical variables and the less-contrast media group. The intravascular ultrasound (IVUS) use rate in the study population was considerably high (94.9%). In multivariable logistic regression analysis, an eGFR < 30 mL/min/1.73 m2 without hemodialysis was significantly associated with the less-contrast media group [odds ratio (OR) 43.73, 95% confidence interval (CI) 14.05-136.09, P < 0.001]. Left main-left anterior descending artery lesion (OR 0.28, 95% CI 0.17-0.48, P < 0.001), bifurcation lesion (OR 0.39, 95% CI 0.16-0.92, P = 0.03), chronic total occlusion (OR 0.22, 95% CI 0.06-0.90, P = 0.03) were inversely associated with the less-contrast media group. In conclusion, complex lesion characteristics were inversely associated with the less-contrast media in elective PCI. Since operators could access patients' renal function before elective procedure, an eGFR < 30 mL/min/1.73 m2 was most significantly associated with the less-contrast media. Our results suggest the possibility that the amount of contrast media is controllable in current PCI under IVUS-guidance.

Determinants of Greater Peak Radiation Skin Dose in Contemporary Percutaneous Coronary Interventions.

BACKGROUND: Skin radiation injuries, especially radiation ulcers, are serious side effects caused by ionizing radiation during percutaneous coronary interventions (PCI). Because skin radiation injuries are closely associated with the peak skin dose, it is important to minimize the peak skin dose. The aim of the present study was to investigate the determinants of greater peak skin dose in current PCI. METHODS: We included 707 consecutive coronary artery lesions, and divided them into an excess radiation group (n = 26; defined as peak skin dose ≥2 Gy) and a standard radiation group (n = 681; defined as peak skin dose <2 Gy). Clinical, lesion, and procedural characteristics were compared between the 2 groups. Univariate and multivariate logistic regression analyses were performed to identify determinants of the excess radiation group. RESULTS: A multivariate logistic regression analysis revealed that body surface area (BSA) [0.1 m2 increase: odds ratio (OR) 1.39, 95% confidence interval (CI) 1.13-1.71, P < 0.01], PCI to a right coronary artery (RCA) (OR 3.11, 95% CI 1.35-7.17, P < 0.01), and PCI to a chronic total occlusion (CTO) (OR 6.69, 95% CI 2.65-16.87, P < 0.01) were significantly associated with the excess radiation group. CONCLUSIONS: Greater BSA, PCI to RCA lesions, and PCI to CTO lesions were significantly associated with excess radiation dose. The first step in the prevention of radiation injuries in current PCI will be to recognize these risk factors.

Appetite Predicts Clinical Outcomes in High Risk Patients Undergoing Trans-Femoral TAVI.

Transcatheter aortic valve implantation (TAVI) has been recognized as a standard therapy for severe aortic valve stenosis. However, since some patients who receive TAVI have poor outcomes, the predictors of clinical outcomes after TAVI are important. The aim of this study was to investigate the association between appetite and long-term clinical outcomes.We screened consecutive cases who received TAVI at our medical center between July 2014 and October 2018. A total of 139 patients who received transfemoral TAVI were included as the final study population. They were divided into a good appetite group (n = 105) and a less appetite group (n = 34) according to their dietary intake rate (> 90%: good appetite group, ≤ 90%: less appetite group). We defined the intake rate as the average for breakfast, lunch, and dinner on the day just before discharge. We defined two-year major adverse cardiovascular and cerebrovascular events (MACCE) as a composite of cardiovascular death, myocardial infarction, any coronary revascularization, history of hospitalization due to heart failure, and disabling acute cerebral infarction. Kaplan-Meier analyses and multivariate Cox regression analysis were performed.The median duration of the follow-up period was 372 (189-720) days. Kaplan-Meier curves showed that the less appetite group got MACCE more frequently (event free rate of the less appetite group: 76.5% versus the good appetite group: 94.3%, Log Rank P = 0.01). In multivariate Cox regression analysis, having less appetite was a significant predictor of two-year MACCE (HR 5.26, 95%CI 1.66-16.71, P < 0.01).In conclusion, among the patients who received transfemoral TAVI, appetite status just before discharge was significantly associated with long-term outcome.

Late presentation of arrhythmogenic right ventricular cardiomyopathy in an octogenarian associated with a pathogenic variant in the plakophilin 2 gene: a case report.

BACKGROUND: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited myocardial disease characterized by fibrofatty replacement and ventricular arrhythmias. ARVC is believed to be a disease of the young, with most cases being diagnosed before the age of 40 years. We report here a case of newly diagnosed ARVC in an octogenarian associated with a pathogenic variant in the plakophilin 2 gene (PKP2). CASE PRESENTATION: An 80-year-old Japanese man was referred for sustained ventricular tachycardia. His baseline electrocardiogram showed negative T waves in V1-V4. Right ventriculography showed right ventricular aneurysm. Because this case met three major criteria, ARVC was diagnosed. He was successfully treated with radiofrequency ablation and oral amiodarone. Genetic analysis identified an insertion mutation in exon 8 of PKP2 (1725_1728dupGATG), which caused a frameshift and premature termination of translation (R577DfsX5). CONCLUSIONS: To the best of our knowledge, this is the first report of newly diagnosed ARVC in an octogenarian associated with a loss-of-function PKP2 pathogenic variant. Although the late clinical presentation of ARVC is rare, it should be included in the differential diagnosis when treating older patients with ventricular tachyarrhythmias.

Determinants of prolonged hospitalization in patients who underwent trans-femoral transcatheter aortic valve implantation.

INTRODUCTION: Transcatheter aortic valve implantation (TAVI) has grown to be an alternative treatment for severe symptomatic aortic valve stenosis (AS) in elderly patients. Although TAVI is a less invasive surgery than surgical aortic valve replacement, some patients may require prolonged hospitalization. AIM: To find the determinants of prolonged hospitalization in patients who underwent trans-femoral TAVI. MATERIAL AND METHODS: A total of 94 AS patients who underwent trans-femoral TAVI were included as the final study population, and divided into the conventional hospitalization group (≤ 21 days) (n = 74) and prolonged hospitalization group (> 21 days) (n = 20). We compared clinical characteristics between the two groups, and multivariate logistic regression analysis was performed to find the determinants of prolonged hospitalization. RESULTS: In multivariate logistic regression analysis, moderate or severe mitral regurgitation (OR = 4.49, 95% CI: 1.16-17.47, p = 0.03), taking statins or angiotensin converting enzyme (ACE) inhibitors/angiotensin II receptor blockers (ARB) on admission (statins: OR = 0.13, 95% CI: 0.02-0.71, p = 0.02, ACE inhibitors/ARB: OR = 0.25, 95% CI: 0.06-0.96, p = 0.04), estimated glomerular filtration rate (eGFR) (per 15 ml/min/1.73 m2 incremental) (OR = 0.49, 95% CI: 0.26-0.90, p = 0.02) and current chopsticks user (OR = 0.05, 95% CI: 0.01-0.41, p < 0.01) were significantly associated with prolonged hospitalization. CONCLUSIONS: Moderate or severe mitral regurgitation was significantly associated with prolonged hospitalization, while current chopsticks user, eGFR (per 15 ml/min/1.73 m2 incremental), taking ACE inhibitors/ARB or statins before the procedure were inversely associated with prolonged hospitalization in patients who underwent trans-femoral TAVI.

Angiotensin Receptor Neprilysin Inhibitor in Japanese Patients With Heart Failure and Reduced Ejection Fraction　- Baseline Characteristics and Treatment of PARALLEL-HF Trial.

BACKGROUND: The objective of the present analyses was to describe the baseline characteristics and treatment of the Japanese patients with HFrEF in THE PARALLEL-HF study. Methods and Results: Key demographic, clinical and laboratory findings, along with treatment, were reported and compared with patients enrolled in the PARADIGM-HF trial and other contemporary randomized clinical trials and registries of Japanese patients with HFrEF. In addition, the MAGGIC and EMPHASIS-HF risk scores were calculated. A total of 225 Japanese patients were randomized in PARALLEL-HF with a mean age of 67.9 years and the majority of the patients being male (85.8%) and in NYHA Class II (93.8%). Key baseline characteristics in PARALLEL-HF were generally comparable with PARADIGM-HF, and other contemporary clinical trials and registries of Japanese HFrEF patients. Patients enrolled in PARALLEL-HF were well treated with conventional evidence-based therapy at baseline (angiotensin-converting enzyme inhibitor inhibitor/angiotensin receptor blocker, 62.7%/37.3%; ß-blockers, 94.7%; mineralocorticoid receptor antagonist, 59.1%). Despite the evidence-based treatment and most patients being in NYHA Class II, these patients had a low LVEF (mean 28.1%) and were at high risk of cardiovascular mortality and morbidity as assessed by the MAGGIC and EMPHASIS-HF risk scores. CONCLUSIONS: Overall, the patients in PARALLEL-HF were largely representative of contemporary ambulatory patients with HFrEF who are well treated with evidence-based therapies. PARALLEL-HF will determine whether sacubitril/valsartan provides similar improvements in clinical outcomes in Japanese HFrEF patients as observed in the PARADIGM-HF study.

Clinical characteristics associated with pacing-induced cardiac dysfunction: a high incidence of undiagnosed cardiac sarcoidosis before permanent pacemaker implantation.

Previous studies suggested that right ventricular pacing was associated with pacing-induced cardiac dysfunction (PICD). The purpose of this study was to investigate the clinical characteristics including the incidence of undiagnosed cardiac sarcoidosis (CS) in patients with atrioventricular block (AVB) who manifest PICD. We retrospectively investigated consecutive patients with permanent pacemaker (PPM) undergoing a first-generator replacement surgery with a new PPM or an upgrade procedure to a cardiac resynchronization therapy (CRT) device between December 1, 2011 and June 30, 2017. Patients with AVB showing normal echocardiographic findings before PPM implantation were included and divided into 2 groups: patients with post-PPM left ventricular ejection fraction (LVEF) < 40% and/or undergoing an upgrade procedure to CRT (PICD group) and patients with post-PPM LVEF ≥ 40% who underwent replacement surgery with a new PPM (no-PICD group). There were 15 and 41 patients in the PICD and no-PICD groups, respectively. A wider-paced QRS duration just after the PPM implantation and/or lower pre-PPM LVEF was observed in the PICD group. Furthermore, 46.7% of the PICD patients (7/15) satisfied the diagnostic criteria for CS according to the guideline of the Japanese Circulation Society, although no patients fulfilled these criteria before PPM implantation. In conclusion, a high incidence of CS was observed in patients with AVB who had PICD. However, none of these patients was diagnosed with CS before PPM implantation.

A Case of Pulmonary Hypertension Associated with Idiopathic Hypereosinophilic Syndrome.

Hypereosinophilic syndrome (HES) is characterized by multi-organ damage that is associated with tissue hypereosinophilia. A persistently elevated eosinophilic count is also required for the diagnosis of HES. Although HES affects various organs, damage to pulmonary artery is rarely reported. We present a case of a 39-year-old man who was diagnosed with pulmonary hypertension (PH) associated with idiopathic HES. Although the pulmonary arterial hypertension specific drugs including intravenous epoprostenol could not control his PH, corticosteroid was effective for both hypereosinophilia and PH. Our case suggests the importance of steroid therapy as well as specific drugs for pulmonary arterial hypertension in the treatment of PH associated with HES.

A Pitfall in the Diagnosis of Bilateral Deep Vein Thrombosis in a Young Man.

A 32-year-old man with a history of bronchial asthma was referred for low back pain and bilateral femur pain. Vascular sonography revealed bilateral deep vein thrombosis (DVT) from the femoral veins to the popliteal veins. Computed tomography revealed hypoplasia of the inferior vena cava (IVC) and dilated lumbar veins, ascending lumbar veins, and azygos vein as collaterals. There was no evidence of malignant neoplasm. The results of the thrombophilia tests were within normal limits. Hypoplasia of the IVC is a rare cause of DVT. This anomaly should be considered as a cause of bilateral and proximal DVT, in particular, in young patients without major risk factors.

The comparison of clinical outcomes in patients with acute myocardial infarction and advanced chronic kidney disease on chronic hemodialysis versus off hemodialysis.

Acute myocardial infarction (AMI) is more frequently observed in patients with chronic kidney disease (CKD) than in patients without CKD. Initial treatment strategy for AMI includes primary percutaneous coronary intervention (PCI), which requires substantial amount of contrast media. We hypothesized that the clinical outcomes are comparable or worse in patients with AMI and advanced CKD off chronic hemodialysis as compared to patients with AMI and advanced CKD on chronic hemodialysis. The purpose of this study was to compare the clinical outcomes of patients with AMI and advanced CKD on hemodialysis versus off hemodialysis. A total of 148 patients with estimated glomerular filtration rate < 30 ml/min/1.73 m2 on admission were included and were divided into the HD group (n = 68) and non-HD group (n = 80). The length of hospitalization was significantly less in the HD group (15.7 ± 14.8 days) than in the non-HD group (22.4 ± 21.3 days) (P = 0.01). In-hospital death was significantly less in the HD group (10.3%) than in the non-HD group (25.0%) (P = 0.02). While the non-HD group was not significantly associated with in-hospital death after controlling clinical covariates, the non-HD group (odd ratio 2.89, 95% confidence interval 1.03-8.12, P = 0.04) was significantly associated with long hospitalization even after controlling clinical covariates. In conclusion, as compared to advanced CKD on chronic hemodialysis, advanced CKD off hemodialysis had higher morbidity and mortality in patients with AMI. Advanced CKD off hemodialysis was closely associated with long hospitalization even after controlling clinical factors.
