RESUMO

The association between polypharmacy/multiple drug use (MDU) and prognosis in patients hospitalized with heart failure (HF) is unclear. It is also unknown whether the prognostic values of MDU vary depending on the presence/absence of a previous history of HF and preserved/reduced left ventricular ejection fraction (LVEF). We analyzed consecutive 1,034 patients hospitalized with HF (age, 74.9 ± 11.5 years; 58.7% male). MDU was defined as ≥5 drugs at discharge. The primary endpoint was a composite of all-cause death and HF readmission. MDU was observed in 695 patients (67.2%). Patients with MDU use had higher prevalences of a previous history of HF, reduced LVEF, and comorbidities than those without MDU. Cox proportional hazard analysis showed that MDU was significantly associated with the primary endpoint after adjustment for possible confounders (hazard ratio [HR], 1.36; 95% confidence interval [CI], 1.03-1.79; P = 0.030). There was significant interaction between the presence/absence of a history of HF and the prognostic impact of MDU (HF history [-]: HR, 0.86; 95% CI, 0.54-1.40; P = 0.553; HF history [+]: HR, 1.72; 95% CI, 1.16-2.55; P = 0.007; P for interaction = 0.005). However, there was no significant interaction between preserved/reduced LVEF and the prognostic impact of MDU (P for interaction = 0.274). In conclusion, MDU at discharge is an independent risk factor for the composite of death or HF readmission in patients hospitalized with HF. We observed a significant interaction between the presence of de novo versus recurrent HF and the prognostic value of MDU.

RESUMO

Background: Although both stellate ganglion blockade and nifekalant are effective treatment options for electrical storm, the clinical effect of their combination is uncertain. Case summary: A 71-year-old male patient was admitted to our hospital with acute myocardial infarction and heart failure. Emergency coronary angiography revealed triple-vessel disease. Although coronary artery bypass grafting was planned, the patient experienced electrical storm before the surgery could be performed. Despite complete revascularization by percutaneous coronary intervention, mechanical circulatory support and administration of antiarrhythmic agents (amiodarone and lidocaine), electrical storm was not controlled. After stellate ganglion blockade was initiated on the 9th day of hospitalization, ventricular arrhythmia decreased. However, when stellate ganglion blockade was temporarily discontinued, ventricular arrhythmia increased substantially. Subsequently, combination therapy with stellate ganglion blockade and nifekalant was initiated, after which ventricular arrhythmia disappeared completely. Afterwards, the patient had no further ventricular arrhythmia episodes, and his haemodynamic status gradually improved. The patient was discharged from hospital in an ambulatory condition and did not experience arrhythmia during the follow-up. Discussion: This case demonstrates that combination therapy with stellate ganglion blockade and nifekalant can completely suppress ventricular arrhythmia, suggesting that blocking multiple conduction pathways is a key to treating refractory electrical storm.

RESUMO

The fibrosis-4 index, albumin-bilirubin score and neutrophil-lymphocyte ratio are all prognostic markers in patients with heart failure. Recently, the FAN score, which includes all 3 of these markers, was developed as a useful risk stratification tool in patients with cancer. However, its cut-off values have not been validated for heart failure. We aimed to investigate the optimal cut-off and prognostic values of the FAN score in patients with heart failure. We analyzed 669 consecutive patients hospitalized with heart failure (age, 75.8 ± 11.3 years). Their median values of the fibrosis-4 index, albumin-bilirubin score, and neutrophil-lymphocyte ratio at discharge were 2.12, -2.25, and 2.41, respectively. The FAN score for heart failure (HF-FAN score) was calculated using these median values. The primary outcome was a composite of all-cause death and heart failure rehospitalization. Patients were divided into 4 groups according to HF-FAN scores of 0 (n = 112), 1 (n = 231), 2 (n = 242) and 3 (n = 84). Patients with HF-FAN scores of 3 were older, had higher brain natriuretic peptide levels, and larger inferior vena cava diameters. Kaplan-Meier analysis showed a direct correlation between higher HF-FAN scores and occurrence of the primary endpoint (log-rank P < 0.001). Cox proportional hazard analysis revealed a higher HF-FAN score was significantly associated with a worse prognosis even after adjustment for possible prognostic factors. Changing from the FAN score to HF-FAN score provided significant continuous net reclassification improvement. In conclusion, the HF-FAN score at discharge was useful for risk stratification in patients hospitalized with heart failure. The HF-FAN score might be more suitable for patients with heart failure than the FAN score.

RESUMO

Sarcoidosis is a multisystem granulomatous disease of unknown cause. With cardiac sarcoidosis (CS), patients represent a wide range of cardiac manifestations from subtle to overt morphological and functional abnormalities. The advent of ultrasound technologies has enabled to identify not only typical findings to CS such as basal thinning of the ventricular septum, but also subclinical myocardial alterations. Based on our recent experiences, we currently introduce a variety of myocardial manifestations evaluated by echocardiography on seven CS patients being selected. Most of the patients exhibited typical cardiac involvement and the remaining fairly unusual.

RESUMO

BACKGROUND: B-type natriuretic peptide (BNP) has been widely used for the diagnosis of heart failure, its severity, and prognosis. However, little is known about factors related to disproportionately low BNP levels even during acute heart failure conditions. METHODS AND RESULTS: Among 424 patients hospitalized for acute heart failure, we categorized the patients into the HFpEF (LVEF > 50%) or HFrEF (LVEF ≤ 50%) group and subdivided them into disproportionately low BNP (LB) group and high BNP (HB) group using a cut-off BNP level of 200 pg/mL at admission. The proportion of patients with LB was higher in the HFpEF group (22.2%) than in the HFrEF group (10.9%, p = 0.002). Patients with LB had a high BMI, lower blood pressure, and history of previous cardiovascular surgery in the HFpEF group, while patients in the HFrEF group had a high BMI and smaller left ventricular end-diastolic volume index. Furthermore, presence of LB in the HFrEF group was related to good prognosis, but LB in the HFpEF group was an indicator of poor prognosis as HB group. CONCLUSIONS: The factors associated with LB were different between the HFpEF and HFrEF groups. LB was related to good prognosis in HFrEF, but not in HFpEF.

RESUMO

We herein report a woman diagnosed with cardiac sarcoidosis (CS) based on the presence of epithelioid granulomas in non-cardiac organs and clinical findings including sustained ventricular tachycardia (VT) and cardiac dysfunction. She stopped oral corticosteroid after 4 years of treatment, and an abnormal myocardial uptake of fluorine-18 fluorodeoxyglucose and sustained VT recurred 3.5 years later. There is no consensus concerning whether or not corticosteroid therapy should be discontinued in the treatment of CS. As a relapse of sarcoidosis-related inflammation may be associated with life-threatening arrhythmia, some patients should continue corticosteroid therapy, even at low doses.

RESUMO

Malnutrition and systemic inflammation are associated with poor outcomes in patients with heart failure. Recent studies have reported that the advanced lung cancer inflammation index (ALI), derived from the body mass index (BMI), serum albumin level, and neutrophil-to-lymphocyte ratio (NLR), is associated with poor prognosis in several types of cancers. Each marker is also known to prognostic factor of heart failure. Therefore, we hypothesized that ALI may be useful for determining the prognosis of patients with acute decompensated heart failure (ADHF). We reviewed survival in 381 consecutive patients (age, 73.1 ± 11.4 years, 59% men) who were hospitalized for ADHF and discharged. ALI at discharge, calculated as BMI × albumin level/NLR, was used to divide the patients into tertiles (ALI < 23.88, 23.88 ≤ ALI < 42.43, and ALI ≥ 42.43). The patients were also stratified into six groups according to the ALI tertiles and median concentration (177 pg/mL) of brain natriuretic peptide (BNP). The primary endpoint comprised all-cause mortality and readmission because of heart failure. The median follow-up duration was 363 days (interquartile range: 147-721 days), and 166 patients (44%) experienced the primary endpoint. Kaplan-Meier analysis showed that the event rate decreased progressively from the first to the third ALI tertile (52%, 48%, and 31%, respectively; p = 0.0013). In a multivariate Cox proportional hazards model, the first tertile was an independent prognostic factor for the primary endpoint (third vs. first tertile: hazard ratio, 0.57; 95% confidence interval, 0.34-0.95; p = 0.031). The hazard ratio for the primary endpoint for the patients with high BNP and first tertile ALI relative to the patients with low BNP and third tertile ALI was 5.3 (95% confidence interval, 2.9-9.5; p < 0.001). ALI at discharge, a novel and simple index of nutrition and inflammation, may be useful for risk stratification and predicting the prognosis of patients with ADHF.

RESUMO

Cardiac sarcoidosis (CS) causes lethal arrhythmia and heart failure and has a poor prognosis; therefore, early detection and early stage treatment are important. However, diagnosis of isolated CS may be difficult in some cases owing to the low sensitivity of myocardial biopsy. Herein, we describe the case of a patient with isolated CS, showing change from negative to positive fluorine-18 fluorodeoxyglucose (18 F-FDG) positron emission tomography (PET) uptake results within 9 months. The patient showed rapid reduction in left ventricular systolic function with sustained ventricular tachycardia. The diagnosis of isolated CS is often under-recognized in clinical practice because it commonly requires the diagnosis of extracardiac disease in the absence of a positive endomyocardial biopsy. The Japanese Circulation Society recently published guidelines for CS diagnosis stating that isolated CS can be clinically diagnosed with positive 18 F-FDG PET or 67 Gallium result. In this case, serial follow-up 18 F-FDG PET was useful for diagnosing isolated CS.

RESUMO

Clinical trials with autologous adipose-derived stem cell (AdSC) therapy for ischemic heart diseases (IHDs) are ongoing. However, little is known about combinational therapeutic effect of AdSCs and statin poly(lactic-co-glycolic) acid (PLGA) nanoparticles on the ischemic myocardium. We investigated the hypothesis that statins, which have pleiotropic effects, augment the therapeutic potential of AdSCs and that AdSCs also act as drug delivery tools. Simvastatin-conjugated nanoparticles (SimNPs) significantly promoted migration activity without changing proliferation activity and upregulated growth factor gene expression in vitro. A small number of intravenously administered SimNP-loaded AdSCs (10,000 cells per mouse) improved cardiac function following myocardial infarction, inducing endogenous cardiac regeneration in the infarcted myocardium. The de novo regenerated myocardium was thought to be derived from epicardial cells, which were positive for Wilms' tumor protein 1 expression. These findings were attributed to the sustained, local simvastatin release from the recruited SimNP-loaded AdSCs in the infarcted myocardium rather than to the direct contribution of recruited AdSCs to tissue regeneration. SimNP-loaded AdSCs may lead to a novel somatic stem cell therapy for IHDs. Stem Cells Translational Medicine 2019;8:1055-1067.

RESUMO

We reported a 67-year-old woman in whom large atrial thrombi were found by chance during discontinuation of therapeutic anticoagulation. The patient, with a history of mitral valve replacement surgery, had stopped anticoagulation for months because of intractable gastrointestinal bleeding, during which she was found to have 3 large thrombi in the atria on transesophageal echocardiography: left atrial free-floating ball-shaped thrombus, left atrial appendage thrombus, and right atrial appendage thrombus. One month following diagnosis, she still had the free-floating thrombus despite adequate anticoagulation. Free-floating ball-shaped thrombus is a rare finding observed on echocardiography in patients with mitral valve disease and an even rarer finding in case of appendage thrombi coexisting.

RESUMO

BACKGROUND: Attenuation correction using segmentation of scatter and photo-peak window data (SSPAC) enables an evaluation of the attenuation map in a patient-specific manner without additional radiation exposure. We compared the accuracy of SSPAC and non-corrected myocardial perfusion scintigraphy methods for diagnosing the number of stenosed coronary artery vessels. METHODS AND RESULTS: We retrospectively reviewed the data from 183 consecutive patients who underwent 99mTc-tetrofosmin stress/rest SPECT examination and a coronary angiography within 3 months. The MPS images were reconstructed with and without SSPAC attenuation correction. We examined the accuracy of the quantitative interpretation using summed differential score in the detection of coronary artery disease (CAD). The attenuation maps were successfully determined in 179 of 183 patients (98%). In terms of the vessel-based diagnostic ability, sensitivity, specificity, positive predictive and negative predictive values of the SSPAC and non-correction methods for diagnosing CAD in individual coronary territories were 77%*, 89%, 74%*, and 90%* vs 51%, 87%, 62%, and 82%, respectively (*P < .05). In 35 patients with multi-vessel CAD, those values were 78%*, 81%, 93%, and 55%* vs 49%, 81%, 89%, and 34%, respectively (*P < .05; AUC: 0.82 vs 0.62, P < .05). CONCLUSION: SSPAC-corrected SPECT myocardial perfusion images exhibit improved accuracy in the detection of the number of stenosed coronary artery vessels, even in patients with multi-vessel CAD.

RESUMO

BACKGROUND Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis of unknown cause accompanied by prominent eosinophilia. Intracardiac thrombosis is one of the major cardiac complications in EGPA that may cause thromboembolism. CASE REPORT A 46-year-old male presenting with intermittent chest pain and numbness of the lower extremities was admitted to our center. His case was complicated by multiple brain infarcts and endocardial thrombosis in the left ventricle. A condition of restrictive cardiomyopathy was also found. After a thorough workup, he was diagnosed with antineutrophil cytoplasmic antibody (ANCA) positive EGPA. Interestingly, the thrombus was accompanied by a pressure gradient producing mid-ventricular obstruction. The patient improved reasonably with immunosuppression and anticoagulation treatment, in addition to heart failure treatment, and had a concomitant regression of the thrombus and reduction of the pressure gradient. CONCLUSIONS For an EGPA patient complicated by intraventricular obstruction caused by endocardial thrombosis, which could accelerate the release of the thrombus into the systemic circulation resulting in a life-threating condition, timely and aggressive measures against cardioembolic complications should be considered.

RESUMO

Several studies have shown that subjects with higher serum bilirubin may have a lower risk of cardiovascular disorders. We herein investigated whether serum bilirubin concentration is associated with lower extremity ischemia among cardiology patients. In total, 935 patients without a history of angioplasty or bypass surgery of the lower limb arteries and who had bilateral ankle-brachial index measurements were included in the study. Peripheral arterial disease (PAD) was defined to be present when ABI of either or both sides was <0.9. Overall, the serum total bilirubin concentration ranged between 0.1 and 2.7mg/dL (normal range, 0.1-1.0mg/dL). Across the bilirubin tertiles, age did not differ significantly. On the other hand, male patients (median 0.6mg/dL, interquartile range (IQR) 0.4-0.7mg/dL) had significantly higher bilirubin levels than female patients (median 0.5mg/dL, IQR 0.4-0.7mg/dL, P=0.014). Logistic regression analysis showed that, as compared with the lowest bilirubin tertile (0.1-0.4mg/dL), the highest tertile (0.7-2.7mg/dL) was significantly negatively associated with prevalent PAD after adjusting for sex, age, eGFR, white blood cell count, inorganic phosphate, HbA1C, total and HDL cholesterol, triglycerides, current smoking, diabetic medication, and statin use. This association remained significant when only those with serum bilirubin in the normal range were included in the analysis. Among cardiology patients, serum bilirubin concentration was significantly negatively associated with prevalence of PAD. The underlying mechanism and therapeutic indications should be investigated in further investigations.

RESUMO

BACKGROUND: The diagnosis of Immunoglobulin G4 (IgG4)-related disease (IgG4-RD), in general, depends on serum IgG4 concentrations and histopathological findings; therefore, diagnosis of IgG4-RD in cardiovascular organs/tissues is often difficult owing to the risk of tissue sampling. METHODS: Prevalence of IgG4-positive lymphoplasmacytic infiltration in 103 consecutive cardiovascular surgical samples from 98 patients with various cardiovascular diseases was analyzed immunohistochemically. RESULTS: The diagnoses of the enrolled patients included aortic aneurysm (abdominal, n = 8; thoracic, n = 9); aortic dissection (n = 20); aortic stenosis (n = 24), aortic regurgitation (n = 10), and mitral stenosis/regurgitation (n = 17). In total, 10 (9.7%) of the 103 specimens showed IgG4-positive cell infiltration with various intensities; five of these were aortic valve specimens from aortic stenosis, and IgG4-positive cell infiltration was present at >10 /HPF in three of them. In one aortic wall sample from an abdominal aortic aneurysm, various histopathological features of IgG4-RD, such as IgG4-positive cell infiltration, obliterating phlebitis, and storiform fibrosis, were observed. CONCLUSIONS: IgG4-positive cell infiltration was observed in 9.7% of the surgical cardiovascular specimens, mainly in the aortic valve from aortic stenosis and in the aortic wall from aortic aneurysm. Whether IgG4-positive cell infiltration has pathophysiological importance in the development or progression of cardiovascular diseases should be investigated in future studies.

RESUMO

Adipose-derived stem cells (AdSCs) have recently been shown to differentiate into cardiovascular lineage cells. However, little is known about the fat tissue origin-dependent differences in AdSC function and differentiation potential. AdSC-rich cells were isolated from subcutaneous, visceral, cardiac (CA), and subscapular adipose tissue from mice and their characteristics analyzed. After four different AdSC types were cultured with specific differentiation medium, immunocytochemical analysis was performed for the assessment of differentiation into cardiovascular cells. We then examined the in vitro differentiation capacity and therapeutic potential of AdSCs in ischemic myocardium using a mouse myocardial infarction model. The cell density and proliferation activity of CA-derived AdSCs were significantly increased compared with the other adipose tissue-derived AdSCs. Immunocytochemistry showed that CA-derived AdSCs had the highest appearance rates of markers for endothelial cells, vascular smooth muscle cells, and cardiomyocytes among the AdSCs. Systemic transfusion of CA-derived AdSCs exhibited the highest cardiac functional recovery after myocardial infarction and the high frequency of the recruitment to ischemic myocardium. Moreover, long-term follow-up of the recruited CA-derived AdSCs frequently expressed cardiovascular cell markers compared with the other adipose tissue-derived AdSCs. Cardiac adipose tissue could be an ideal source for isolation of therapeutically effective AdSCs for cardiac regeneration in ischemic heart diseases. Significance: The present study found that cardiac adipose-derived stem cells have a high potential to differentiate into cardiovascular lineage cells (i.e., cardiomyocytes, endothelial cells, and vascular smooth muscle cells) compared with stem cells derived from other adipose tissue such as subcutaneous, visceral, and subscapular adipose tissue. Notably, only a small number of supracardiac adipose-derived stem cells that were systemically transplanted sufficiently improved cardiac functional recovery after myocardial infarction, differentiating into cardiovascular cells in the ischemic myocardium. These findings suggest a new autologous stem cell therapy for patients with myocardial ischemia, especially those with secondary myocardial ischemia after cardiovascular open chest surgery.

RESUMO

AIM: Fibroblast growth factor 23 (FGF23) and α-Klotho have been recently identified to play a crucial role in calcium/phosphate metabolism. We herein investigated the possible relation between serum FGF23/α-Klotho levels and coronary artery calcification (CAC) and aortic valve calcification (AVC). METHODS: Among subjects with diagnosed or suspected coronary artery disease (CAD), CAC and AVC were estimated via the Agatston score of 320-detector computed tomography images, and serum FGF23 and α-Klotho levels were measured. RESULTS: In total, 157 subjects were enrolled (75 women and 82 men). We performed logistic regression using CAC as a dependent variable; the highest FGF23 tertile (> 52.5 pg/mL) was significantly positively associated with CAC with an odds ratio of 6.61 versus the lowest FGF23 tertile (< 35.3 pg/mL) in women after the adjustment for potential confounding variables including age, renal function, hypertension, statin use, diuretic use, and calcium/phosphate metabolism related factors. In addition, the highest α-Klotho tertile (> 561 pg/mL) was significantly associated with AVC with an odds ratio of 6.31 versus the lowest α-Klotho tertile (< 306 pg/mL) in men after adjusting for the same variables. On the other hand, the association between FGF23 and CAC/AVC in men or that between α-Klotho and CAC/AVC in women was nonsignificant. CONCLUSION: Among subjects with diagnosed or suspected CAD, serum FGF23 was positively associated with CAC in women and serum α-Klotho was positively associated with AVC in men independent of the confounding variables, including the renal function and calcium/phosphate metabolism-related factors.

RESUMO

A 67-year-old woman was referred to our hospital due to a refractory lower extremity ulcer. Occlusion of the bilateral superficial femoral arteries and a difference (>50 mmHg) in blood pressure between the bilateral upper limbs were noted. In addition to occlusion of the left subclavian artery and stenosis at the ostium of the right coronary artery, these findings led to a diagnosis of Takayasu arteritis. Furthermore, a biopsy of the ulcerated skin lesion localized on the fibular surface showed a non-caseating cutaneous granulomatous lesion resulting in the diagnosis of cutaneous sarcoidosis. The simultaneous occurrence of cutaneous sarcoidosis and Takayasu arteritis, albeit rare, should not be overlooked.

RESUMO

A 36-year-old man presented with near-syncope. He was found to have massive pericardial effusion with a giant pericardial tumorous lesion. The pericardial effusion exhibited a bloody nature; however, neither malignant cells nor infectious organisms were detected. (18)F-fluorodeoxyglucose-positron emission tomography (FDG-PET) showed an increased uptake of FDG in the pericardial tumor only. Although the tumor was not resectable, thoracotomy and tissue sampling were performed. A histological analysis showed CD99 positivity and SYT gene rearrangement, leading to a diagnosis of synovial sarcoma arising from the left lateral pericardial surface. The patient is now receiving chemotherapy.

RESUMO

A 48-year-old woman was referred to the cardiology department due to a large mobile mass in the right ventricle. The patient had undergone radical hysterectomy and bilateral salpingo-oophorectomy for a uterine squamous cell carcinoma approximately 3.5 years before. In order to protect the patient from circulatory collapse, the intracardiac mass was resected surgically. A diagnosis of cardiac metastasis of the uterine cervical squamous cell carcinoma was confirmed histologically. Herein we discuss the possible therapeutic approach to and prognosis of this rare condition by reviewing 24 papers on intracardiac uterine cancer metastasis published in the past 10 years. .
