RESUMO

PURPOSE: Neck and upper-back stiffness is encountered in daily life, with symptoms appearing as dullness or aches predominantly in the trapezius muscle (TM). Our previous study demonstrated that TM hardness as measured with a muscle hardness meter correlates well with transverse cervical artery (TCA) flow supplying the TM. Muscle hardness meters, however, cannot measure hardness in the TM alone. Meanwhile, recent advances in ultrasound elastography have enabled the evaluation of localized hardness in targeted tissues. The present study, therefore, aimed to clarify the relationship between TM hardness as measured by elastography and TCA hemodynamics as measured on Doppler sonography, with reference to daily symptoms of upper-back stiffness. METHODS: The study population comprised 66 healthy young adults (32 males, 34 females; mean age, 21 ± 1 years). Relationships were evaluated between TM hardness as a negative correlate of strain ratio from elastography and TCA hemodynamics on Doppler sonography. Hemodynamics in the TCA were evaluated according to the frequency of neck and upper-back stiffness. RESULTS: TM strain ratio correlated with peak systolic velocity (PSV) in the TCA (r = 0.273, p = 0.036), particularly in symptomatic subjects (r = 0.417, p = 0.022). PSV in the TCA decreased with increasing frequency of daily symptoms (p = 0.045). CONCLUSION: TCA hemodynamics correlated with muscle hardness when evaluating localized TM hardness. This relationship and low PSV in the TCA were evident in symptomatic subjects. These results suggest that PSV in the TCA is associated with neck and upper-back stiffness.

RESUMO

PURPOSE: Taking a short rest after lunch suppresses increases in blood flow to the digestive organs and maintains blood flow to the brain in the afternoon, possibly providing beneficial effects in preventing post-prandial drowsiness. The present study investigated sex-dependent influences on changes in hemodynamics produced by taking a short rest after lunch. METHODS: Subjects comprised 20 healthy young adults (10 men, 10 women; mean age 21 ± 1 years). Doppler sonography was performed to measure blood flow in the superior mesenteric artery (SMA) and common carotid artery (CCA) before and after lunch every hour on each day, with and without a 15-min rest with eyes closed after lunch. Blood pressure and heart rate (HR) were also measured. RESULTS: For both men and women, peak systolic velocity (PSV) in the SMA was suppressed by taking a rest. PSV in the CCA in men was increased at 0.5 h after lunch in the resting condition but was decreased in the non-resting condition (median 109%, interquartile range [IQR] 102-120% vs. median 98%, IQR 90-107%; P = 0.037). No such differences were observed in women. Although post-prandial increases in HR were observed in women, a similar increase was only found for men in the resting condition. CONCLUSION: An increase in CCA blood flow was observed only in men. The present study suggests that a short rest after lunch could better promote the maintenance of blood flow to the brain in men than in women.

RESUMO

BACKGROUND: Pathophysiologically, an elevated left ventricular (LV) filling pressure is the major reason for heart failure (HF) readmission. The 2016 American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI) guidelines provide a simplified algorithm for the echocardiographic assessment of LV filling pressure; however, this algorithm is yet to be sufficiently validated. MATERIALS AND METHODS: We retrospectively studied 139 consecutive patients with acute decompensated HF. High estimated left atrial pressure (eLAP) was defined according to the 2016 ASE/EACVI guidelines. Univariate and multivariate logistic regression analyses were performed to identify significant risk factors for HF readmission within one year of discharge. RESULTS: Across the study cohort, 68 patients (49%) did not have a high eLAP, 32 (23%) had an indeterminate eLAP, and 39 (28%) had a high eLAP. The number of HF readmission events within one year in the without high eLAP, indeterminate, and high eLAP groups were 4 (7.5%), 5 (18.5%), and 10 (33.3%), respectively. The HF readmission rate was significantly higher in patients with high eLAP than in those without high eLAP. Multivariate analysis revealed high eLAP (odds ratio, 5.924; 95% confidence interval, 1.664-21.087; P = 0.006) as a significant risk factor for HF readmission within one year. Furthermore, the exploratory analysis of the two-year outcomes revealed a similar finding: patients with high eLAP had a significantly higher rate of readmission for HF. CONCLUSIONS: The present study demonstrated that echocardiographic assessment of elevated LAP based on the 2016 ASE/EACVI guidelines is clinically valid for predicting readmission in patients with HF.

RESUMO

BACKGROUND: Hypoalbuminemia is common in critically ill patients and is associated with poor outcomes. However, the relationship between serum albumin levels and clinical outcomes in patients with takotsubo syndrome remains unclear. We examined the impact of hypoalbuminemia on in-hospital mortality in patients with takotsubo syndrome. METHODS: Using the multicenter registry of the Tokyo Cardiovascular Care Unit Network between January 2017 and December 2020, we identified 631 eligible patients with takotsubo syndrome (median age, 78 years; male proportion, 22 %) and documented serum albumin levels at admission, which were used to allocate patients to hypoalbuminemia (serum albumin <3.5 g/dL) or normal albumin (serum albumin ≥3.5 g/dL) groups. Patient characteristics and in-hospital mortality were compared between the groups. RESULTS: Hypoalbuminemia was detected in 200 (32 %) patients at admission. The hypoalbuminemia group was older and had a higher proportion of men and preceding physical triggers than the normal albumin group. In-hospital all-cause mortality was greater in the hypoalbuminemia group than in the normal albumin group (9.5 % vs. 1.9 %, p < 0.001). Both cardiac (3.0 % vs. 0.5 %, p = 0.015) and non-cardiac (6.5 % vs. 1.4 %, p = 0.002) mortality was greater in the hypoalbuminemia group. In multivariable logistic regression analysis, hypoalbuminemia was independently associated with increased in-hospital mortality, even after adjusting for confounders, including age, sex, and triggering events (odds ratio, 3.23; 95 % confidence interval, 1.31-7.95; p = 0.011). CONCLUSIONS: In patients with takotsubo syndrome, hypoalbuminemia is a common comorbidity and is associated with a substantial risk of in-hospital death. Close monitoring and comprehensive critical care are required in these patients.

RESUMO

Left atrial appendage (LAA) closure may prevent atrial fibrillation (AF)-induced thromboembolism. We describe a rare case of right atrial (RA) thrombus after thoracoscopic left atrial appendectomy and pulmonary vein isolation. Careful evaluation for the presence of RA thrombus in patients with persistent AF after LAA occlusion may be necessary. (Level of Difficulty: Intermediate.).

RESUMO

BACKGROUND: Takotsubo syndrome (TTS) is an acute cardiovascular disease with clinical manifestations similar to those of acute myocardial infarction (AMI), and TTS sometimes occurs just after catastrophes. Large-scale studies of TTS in Japan are scarce, so we examined data over 9 years from Tokyo metropolitan acute cardiovascular care hospital network registry. METHODS: A total of 1626 patients were diagnosed with TTS between 2010 and 2018 at Tokyo Cardiovascular Care Unit Network facilities, and data from all these patients were analyzed. We investigated annual and monthly captured incidence of TTS, temporal trend of the captured incidence proportion of TTS versus AMI, the occurrence of TTS on the day of the great earthquake, and we elucidated the prognostic factors for in-hospital death. RESULTS: The annual incidence proportion of TTS versus AMI increased from 2.3 % to 4.5 % (p < 0.001) over 9 years. The mean TTS patient age was 74.4 years: the peak incidence of TTS was at 80 to 84 years of age for both male and female; females accounted for 78.5 % of patients. The monthly variation of the incidence of TTS was found (p = 0.009). In 2011, a total of 137 cases of TTS occurred, with as many as 6 occurring on March 11, the day of the Great East Japan Earthquake. There was a definable trigger for TTS in 64 % (physical: 36 %; emotional: 27 %; others: 2 %). All-cause in-hospital mortality was 5.3 % and was higher in males than in females (10.3 % vs 3.9 %; p < 0.001). Non-cardiac causes accounted for 62 % of in-hospital mortality. Factors at presentation that were associated with in-hospital all-cause mortality were male sex, low body mass index, and a high C-reactive protein level. CONCLUSIONS: This study elucidated the clinical features, in-hospital outcomes, and their attributed factors in patients with TTS in real-world clinical practice in Japan.

RESUMO

Mitral annular early diastolic velocity (e') measured using Doppler echocardiography is important for the noninvasive estimation of left ventricular filling pressure (LVFP). However, it remains unknown whether lateral or septal e' is prognostically more reliable. Accordingly, here, we compared the prognostic utility of lateral e' with that of septal e' in patients hospitalized for acute decompensated heart failure (HF). We retrospectively analyzed the data of 193 consecutive patients with acute decompensated HF. According to the 2016 American Society of Echocardiography/European Association of Cardiovascular Imaging guidelines, the cut-off values of high lateral e' and septal e' were 10 cm/s and 7 cm/s, respectively. Kaplan-Meier survival curves and log-rank tests were used to compare 90-day mortality between groups. For the entire cohort, 90-day mortality was 15.5%. Lateral e' <10 was significantly correlated with higher 90-day mortality (log-rank, P = 0.026), whereas septal e' <7 was not significantly associated with 90-day mortality (log-rank, P = 0.405). Receiver operating characteristic curve analyses revealed that the best cut-off values for lateral e' and septal e' in this cohort were 10 cm/s and 6 cm/s, respectively. However, septal e' <6 was also not associated with 90-day mortality (log-rank, P = 0.141). This study demonstrated that, when comparing lateral e' with septal e', the former provides better prognostic utility for patients with acute decompensated HF. If a dissociation between lateral e' and septal e' is detected, the value measured at the lateral site may be more credible for determining LVFP in HF.

RESUMO

Although current guidelines recommend the use of prostanoid infusion that includes epoprostenol for high-risk pulmonary arterial hypertension patients, epoprostenol has many adverse effects. We report a case of a heritable pulmonary arterial hypertension patient who had transient biventricular hypertrophy during high-dose administration of epoprostenol. In this case, biventricular hypertrophy with worsening of dyspnea was observed during the uptitration of epoprostenol. Inflammatory diseases and endocrine disorders were ruled out as causes of the ventricular hypertrophy. After epoprostenol was changed to intravenous treprostinil, the biventricular hypertrophy normalized, in connection with dyspnea improvement. The use of high-dose epoprostenol may contribute to cardiac hypertrophy.


Bien que les lignes directrices en vigueur recommandent les perfusions de prostanoïdes comprenant de l'époprosténol chez les patients à risque élevé atteints d'hypertension artérielle pulmonaire, les effets indésirables de l'époprosténol sont nombreux. Nous décrivons ici le cas d'un patient atteint d'hypertension artérielle pulmonaire héréditaire ayant présenté une hypertrophie biventriculaire transitoire pendant le traitement par de l'époprosténol à dose élevée. Pour ce patient, une hypertrophie biventriculaire accompagnée d'une aggravation des symptômes de dyspnée ont été observées lors de l'ajustement à la hausse de la dose d'époprosténol. Les maladies inflammatoires et les troubles endocriniens ont été écartés comme facteurs étiologiques de l'hypertrophie ventriculaire. Après le remplacement de l'époprosténol par du tréprostinil intraveineux, l'hypertrophie biventriculaire s'est résorbée, et les symptômes de dyspnée se sont atténués. Il semble donc que l'utilisation de l'époprosténol à dose élevée puisse contribuer à l'hypertrophie cardiaque.

RESUMO

Despite the poor prognosis of systemic sclerosis (SSc) due to the co-occurrence of left ventricular diastolic dysfunction (LVDD), presence of occult LVDD has not been sufficiently investigated. This retrospective study aimed to reveal the prevalence and determinants of occult LVDD in patients with SSc by exercise stress test. Forty-five SSc patients (age, 63 ± 13 years; men/women, 6/39) with normal pulmonary artery pressure and pulmonary artery wedge pressure (PAWP) at rest underwent a symptom-limited exercise test with right heart catheterization using a supine cycle ergometer; haemodynamic parameters at rest, leg raise and during exercise were evaluated. Occult LVDD defined PAWP ≥ 25 mmHg during exercise was seen in 13 patients (29%). Higher PAWP, lower pulmonary vascular resistance and diastolic pulmonary pressure gradient, larger left atrium at rest, and higher PAWP during leg raise (15 ± 4 vs 10 ± 4 mmHg in non-LVDD group, p < 0.001) were observed in the occult LVDD group. The area under the ROC curve for PAWP after leg raise was largest at 0.83 (95% CI: 0.70-0.95, p = 0.001). About one-third (29%) of SSc patients with normal haemodynamics at rest showed occult LVDD. A higher PAWP after leg raise could be useful for detecting occult LVDD.

RESUMO

INTRODUCTION: Exercise pulmonary hypertension is common in patients with chronic thromboembolic pulmonary hypertension (CTEPH) who experience shortness of breath during exercise and reduced exercise capacity despite normalised pulmonary arterial pressure (PAP) at rest; however, the relationship between exercise pulmonary hypertension and exercise capacity remains unclear. Here we aimed to determine whether exercise pulmonary hypertension is related to exercise capacity and ventilatory efficiency in CTEPH patients with normalised resting haemodynamics after pulmonary balloon angioplasty (BPA). PATIENTS AND METHODS: In total, 249 patients with CTEPH treated with BPA (mean±sd age 63±14 years; male:female 62:187) with normal mean PAP (mPAP) (<25 mmHg) and pulmonary arterial wedge pressure (≤15 mmHg) at rest underwent cardiopulmonary exercise testing with right heart catheterisation. mPAP-cardiac output (CO) during exercise was plotted using multipoint plots. Exercise pulmonary hypertension was defined by a mPAP-CO slope >3.0. RESULTS: At rest, pulmonary vascular resistance was significantly higher in the exercise pulmonary hypertension group (n=116) than in the non-exercise pulmonary hypertension group (n=133). Lower peak oxygen consumption (13.5±3.8 versus 16.6±4.7 mL·min-1·kg-1; p<0.001) was observed in the former group. The mPAP-CO slope was negatively correlated with peak oxygen consumption (r= -0.45, p<0.001) and positively correlated with the minute ventilation versus carbon dioxide output slope (r=0.39, p<0.001). CONCLUSIONS: Impaired exercise capacity and ventilatory efficiency were observed in patients with CTEPH who had normalised PAP at rest but exercise pulmonary hypertension.

RESUMO

BACKGROUND: Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly that results in high mortality if left untreated. Our aim was to extend our knowledge of the histological, angiographic, and clinical characteristics of ALCAPA in order to deepen our understanding of this rare entity. CASE PRESENTATION: We were involved in the assessment, treatment, and pathological evaluation of two adult ALCAPA patients who were rescued from ventricular fibrillation and then surgically treated to establish a dual coronary artery system. Histological studies indicated various chronic ischemic changes in the myocardium, patchy fibrosis, and severely thickened arteriolar walls in both ventricles. The first patient is alive and well 11.5 years after surgical correction without any implantable cardioverter defibrillator (ICD) activations. The second patient required re-do surgery 9 months after the initial operation but subsequently died. Histologically, chronic ischemic alteration of the myocardium and thickened arteriolar walls persisted even after surgical correction, and coronary angiography (CAG) showed an extremely slow flow phenomenon even after surgical correction in both patients. The average postoperative opacification rate in the first case was 7.36 + 1.12 (n = 2) in the RCA, 3.81 + 0.51 (n = 3) in the left anterior descending (LAD) artery, and 4.08 + 0.27 (n = 4) in the left circumflex (LCx) artery. The slow flow phenomenon may represent persistent high arteriolar resistance in both ventricles. CONCLUSIONS: Seldom reported or new findings in adult ALCAPA were identified in two cases. More frequent diagnosis of adult ALCAPA can be expected because of the widespread availability of resuscitation and more advanced diagnostic modalities. Accumulation of pathological and clinical findings and confirmation of the long-term follow-up results after treatment may contribute to expanding our knowledge of this rare entity and establishing optimal treatment.

RESUMO

BACKGROUND: Takotsubo syndrome occasionally occurs in patients with fever due to underlying diseases. However, the impact of body temperature on inhospital prognosis of patients with takotsubo syndrome remains unknown. METHODS: Using the patient cohort in the Tokyo Cardiovascular Care Unit Network Registry from 2013 to 2015, we identified 421 eligible patients whose data on body temperature at admission were available and classified them into three groups: high body temperature group (≥37.5°C; n=27), normal body temperature group (36.0-37.4°C; n=319), and low body temperature group (≤35.9°C; n=75). We compared the patient characteristics and inhospital outcomes among the three groups. RESULTS: On admission, the high body temperature group showed a higher proportion of men and preceding physical triggers, higher heart and respiratory rates, and higher C-reactive protein level than the other groups. Inhospital all-cause mortality was significantly higher in the high body temperature group than in the normal or low body temperature group (18.5% vs. 2.2% vs. 4.0%, respectively, P<0.001). Both cardiac mortality (11.1% vs. 1.3% vs. 1.3%, P=0.001) and non-cardiac mortality (7.4% vs. 0.9% vs. 2.7%, P=0.031) were also significantly higher in the high body temperature group. Multivariable logistic regression analysis showed that high body temperature (reference: normal body temperature) was significantly associated with higher inhospital mortality (adjusted odds ratio 4.22; 95% confidence interval 1.15-15.51; P=0.030). CONCLUSIONS: Our findings suggest that high body temperature at admission is a strong predictor of inhospital mortality in patients with takotsubo syndrome. Febrile takotsubo syndrome patients may need to be managed with recognition of life-threatening conditions from the time of diagnosis, no matter what the causes of fever are.

RESUMO

BACKGROUND: Exercise-induced pulmonary hypertension (PH) is often seen in chronic thromboembolic PH (CTEPH) patients with normalized resting hemodynamics, but it is difficult to differentiate precapillary PH as pulmonary vascular dysfunction and post-capillary PH from occult-left ventricular dysfunction (LVD). The aim of this study was to examine whether the exercise-induced elevation of pulmonary arterial wedge pressure (PAWP) can be predicted by the echocardiographic index at rest.Methods and Results:A total of 71 CTEPH patients (67±11 years old, male/female=15/56) treated by pulmonary angioplasty with near-normal pulmonary arterial pressure (PAP) and normal PAWP at rest underwent symptom-limited exercise test using supine cycle ergometer with right heart catheterization. Exercise-induced elevation in PAWP of >20 mmHg during exercise was defined as occult-LVD. Resting echocardiography was performed within 3 months. In the occult-LVD (n=28), PAWP at rest after leg raising for exercise (14±4 vs. 11±3 mmHg, P<0.001), and mean PAP during exercise were higher compared with the non-LVD (n=43). Peak oxygen consumption, cardiac output, and pulmonary vascular resistance at peak exercise did not differ between groups. Left atrial volume index (LAVi) in the occult-LVD was significantly larger (39.7±8.1 vs. 34.4±9.6 mL/m2, P=0.017). LAVi correlated with exercise PAWP (r=0.356, P=0.002), but not resting PAWP (r=0.161, P=0.179). CONCLUSIONS: Larger left atrial volume may reflect the exercise-induced PAWP elevation as occult-LVD in CTEPH patients.

RESUMO

The pathophysiology and treatment of acute decompensated heart failure (HF) in the presence of chronic kidney disease (CKD) remain ill defined. Here we compared the prognostic factors for 1-year mortality in patients with acute HF with and without CKD. We retrospectively studied 392 consecutive patients with acute decompensated HF. CKD as a comorbidity in these patients was defined by an estimated glomerular filtration rate of <60 mL/min/1.73 m2. Potential risk factors for 1-year mortality were selected by univariate analyses; then multivariate Cox regression analysis with forward selection (likelihood ratio) was performed to identify significant factors. Across the study cohort, 65% of patients had CKD, and the 1-year mortality rate was 9.2%. In the HF with CKD group, older age, lower systolic blood pressure at admission, discharge medications without beta-blockers, and discharge medications without diuretics were independent risk factors for 1-year mortality. In contrast, coexisting chronic obstructive pulmonary disease and higher C-reactive protein levels were independent risk factors for 1-year mortality in the HF without CKD group. Kaplan-Meier survival curves showed that discharge medications with no beta-blockers or diuretics correlated with significantly lower survival rates in patients with CKD (P < 0.001 in both groups, log-rank test), but not in patients without CKD (P = 0.822 and P = 0.374, respectively, log-rank test). Thus, there were significant differences in the prognostic factors for 1-year mortality between acute HF patients with and without CKD including beta-blocker and diuretic treatments. These findings suggest that patients with HF might benefit from individualized therapies.

RESUMO

Background: The relationship between outcome and trigger in takotsubo syndrome (TTS) has been recently discussed, but the data are still limited. Methods and Results: We enrolled 745 consecutive patients with TTS from the Tokyo Cardiovascular Care Unit Network registry. The patients were divided into 4 groups based on trigger: (1) medical illness, 202 (27%); (2) physical activity, trauma and injury, 54 (7%); (3) emotional trigger, 199 (27%); and (4) unidentifiable trigger, 290 (39%). Compared with other groups, the medical illness group had the lowest percentage of female patients (68%, 85%, 89%, and 79%, respectively; P<0.001) and the highest mean patient age (75±11 years, 72±11, 73±12, and 75±11 years, respectively; P=0.02). In-hospital all-cause mortality was higher (11%) in this group (0%, 2%, and 2%, respectively; P<0.001). On multivariate logistic regression analysis, the medical illness group independently predicted all-cause death (OR, 4.73; 95% CI: 1.33-16.87); although there was no significant difference in cardiac deaths between the 4 groups. Conclusions: TTS has a wide spectrum of outcome depending on the trigger. The medical illness trigger was a powerful predictor of outcome but the main cause of death is not cardiac complication.

RESUMO

BACKGROUND:: Although the typical apical form of Takotsubo syndrome and anterior acute myocardial infarction have similar electrocardiographic and echocardiographic presentations, data on the clinical differences between the two disorders are limited. METHODS:: Using the Tokyo Cardiovascular Care Unit network registry, we identified patients hospitalised with apical Takotsubo syndrome ( n=540; 2010-2014) or anterior acute myocardial infarction ( n=2,806; 2013-2014) and created 522 age and sex-matched pairs (mean age 74.1 years; women 78.5%). We compared the clinical characteristics and inhospital outcomes between the two groups. RESULTS:: On admission, patients with apical Takotsubo syndrome showed a lower body mass index, less frequent chest pain/tightness, lower systolic blood pressure, higher heart rate, lower creatine kinase, higher C-reactive protein and brain natriuretic peptide, and less frequent ST-elevation than patients with anterior acute myocardial infarction. Patients with apical Takotsubo syndrome received catecholamine (12.8% vs. 24.5%, P<0.001) and intra-aortic balloon pumping (5.9% vs. 15.1%, P<0.001) less frequently. Despite similar all-cause mortality (5.4% vs. 7.9%, P=0.134), patients with apical Takotsubo syndrome showed lower cardiac mortality (2.1% vs. 6.7%, P<0.001; risk difference -4.6% (95% confidence interval -7.1% to -2.1%)) but higher non-cardiac mortality (3.3% vs. 1.1%, P=0.033; 2.1% (0.3%-3.9%)). In subgroup comparisons, patients with physically triggered Takotsubo syndrome had higher non-cardiac mortality (7.0%) than those with non-physically triggered Takotsubo syndrome (1.2%, P=0.001) or anterior acute myocardial infarction (1.1%, P<0.001). CONCLUSIONS:: This study found that cardiac and non-cardiac mortality risks differed significantly between apical Takotsubo syndrome and anterior acute myocardial infarction. Our findings underscore the importance of differentiating between the two disorders for appropriate management.

RESUMO

OBJECTIVES: To evaluate the association between high estimated pulmonary artery systolic pressure (ePASP) obtained by echocardiography and 1-year mortality in patients with acute heart failure (HF), comparing findings in individuals aged 80 and older with those of individuals younger than 80. DESIGN: Retrospective cohort study. SETTING: Kyorin University Hospital. PARTICIPANTS: Individuals with acute decompensated HF (N = 335). MEASUREMENTS: High ePASP was defined as a tricuspid regurgitation pressure gradient greater than 47 mmHg (ePASP >50 mmHg). Potential risk factors for 1-year mortality were selected using univariate analysis followed by multivariate Cox regression analysis with backward stepwise selection of variables with P < .10 on univariate analysis to identify significant factors. RESULTS: In individuals aged 80 and older, high ePASP (hazard ratio (HR)=3.07; 95% confidence interval (CI)=1.21-7.80), discharge medications without diuretics (HR=4.18, 95% CI=1.66-10.54), and discharge medications without renin-angiotensin-aldosterone system inhibitors (HR=3.38, 95% CI=1.29-8.81) were independent risk factors for 1-year mortality. In contrast, low systolic blood pressure at admission was the sole independent risk factor for 1-year mortality (HR=0.94, 95% CI=0.89-0.99) in those younger than 80. CONCLUSION: High ePASP is a significant predictor of 1-year mortality in individuals aged 80 and older with acute HF but not in those younger than 80. Elucidation of the pathophysiological mechanisms behind these findings should facilitate the development of more effective individualized therapies for older adults with acute HF.

RESUMO

Blunt chest trauma may lead to cardiac involvement such as myocardial contusion, coronary artery dissection, cardiac rupture, or myocardial infarction. Early detection and treatment of complications such as these are essential. We describe a case status post collision with an iron ball and discuss how to detect myocardial infarction. We emphasize the importance of careful interview, physical examination, and electrocardiogram even in seemingly healthy patients. A severe blow, such as that described, can impair coronary artery flow and may potentially cause myocardial infarction.

RESUMO

With advances in cancer chemotherapy, the importance of the new clinical discipline of cardio-oncology, which is concerned with the cardiac effects of chemotherapy, is increasing. Herein we describe the case of a 48-year-old woman with a history of breast cancer who presented with symptoms of heart failure due to chemotherapy-induced cardiomyopathy. Treatment for the patient's breast cancer had included surgery and chemotherapy with anthracyclines and trastuzumab. Echocardiography revealed multiple mobile thrombi in the left ventricle and atrium. In addition, brain magnetic resonance imaging revealed small acute cerebral infarctions due to embolization. Given the high risk of re-embolization, surgical thrombectomy was performed. Thus far, there are no standardized therapeutic guidelines for left-sided cardiac thrombi and the optimal treatment remains contentious. Although this patient was managed successfully with surgical thrombectomy, patients should be managed individually, taking into consideration embolization, bleeding, and surgical risks. With further improvements in cancer chemotherapy, there may be an increase in the incidence of complications such as multiple cardiac thrombi. From the cardio-oncology standpoint, we propose close interactions between cardiologists and oncologists for the optimal care of cancer patients.

RESUMO

BACKGROUND: Pulmonary artery aneurysm (PAA) occurs in some patients with pulmonary arterial hypertension (PAH). We evaluated the characteristics of cardiac dysfunction in patients with PAH complicated by PAA. METHODS: Echocardiography and right-heart catheterization were performed in 130 PAH patients to measure the maximum dimensions of the main pulmonary artery (MPA) trunk and evaluate right ventricular (RV) and left ventricular (LV) function. RESULTS: A diameter of >40mm was defined as PAA in the MPA trunk. The maximum MPA diameter was >40mm in 32 of 130 PAH patients (24.6%: Group PAA). Systolic pulmonary artery pressure (68.0±18.5 vs. 58.9±21.6mm Hg, P=0.0354) and pulmonary capillary wedge pressure (10.8±3.9 vs. 7.7±2.6mm Hg, P<0.0001) were significantly higher in Group PAA than in Group non-PAA. RV end-diastolic area index (19.6±6.8 vs. 14.9±5.1 cm²/m², P<0.0001), and RV fractional area change (32.3±7.8 vs. 37.3±8.8%, P=0.0048) and RV longitudinal strain (-15.4±5.1 vs. -20.4±6.1, P=0.0012) were significantly lower, and E/e' was significantly higher (8.1±2.2 vs. 6.7±1.4, P=0.0002) in Group PAA than in Group non-PAA. CONCLUSIONS: In PAH patients with PAA, RV was larger and RV dysfunction was more severe, and LV diastolic dysfunction appeared. It is important to investigate the appearance of PAA and the severity of RV and LV dysfunction in PAH patients with PAA.
