Commercial massage tool-induced spinal epidural hematoma.

Background: Spinal epidural hematoma (SEH), which may develop into an emergency condition, is a rare disease. Here, we present the case of a patient with SEH caused by cervical massage using a commercial massage tool. Case Presentation: A 75-year-old man was brought to our hospital with a chief complaint of posterior neck pain during sleep. He had used a commercial massage tool before going to bed. Upon arrival, hypotension and respiratory failure were observed. His muscle strength in both the upper and lower extremities rated 0 on the manual muscle test, and sensory loss below the papillae was observed. His symptoms resolved spontaneously after 2 h. Magnetic resonance imaging suggested a spinal cord epidural hematoma at the C2/C3 to C3/C4 level. On day 6, the patient was discharged without any impairment. Conclusion: Fatal complications could occur by cervical massage using a commercial massage tool.

Intestinal obstruction caused by consuming diet food containing psyllium.

A 26-year-old man presented to our institution with abdominal pain and nausea after eating food containing Psyllium to lose weight. Since patients undergoing extreme slimming regimens may cause intestinal obstruction if psyllium is taken without adequate fluid intake caution should be taken when eating psyllium.

Rationale, Design, and Baseline Characteristics of the CURRENT AS Registry-2.

BACKGROUND: There is scarce data evaluating the current practice pattern and clinical outcomes for patients with severe aortic stenosis (AS), including both those who underwent surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI) and those who were managed conservatively in the TAVI era.Methods and Results: The Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis (CURRENT AS) Registry-2 is a prospective, physician-initiated, multicenter registry enrolling consecutive patients who were diagnosed with severe AS between April 2018 and December 2020 among 21 centers in Japan. The rationale for the prospective enrollment was to standardize the assessment of symptomatic status, echocardiographic evaluation, and other recommended diagnostic examinations such as computed tomography and measurement of B-type natriuretic peptide. Moreover, the schedule of clinical and echocardiographic follow up was prospectively defined and strongly recommended for patients who were managed conservatively. The entire study population consisted of 3,394 patients (mean age: 81.6 years and women: 60%). Etiology of AS was degenerative in 90% of patients. AS-related symptoms were present in 60% of patients; these were most often heart failure symptoms. The prevalence of high- and low-gradient AS was 58% and 42%, respectively, with classical and paradoxical low-flow low-gradient AS in 4.6% and 6.7%, respectively. CONCLUSIONS: The CURRENT AS Registry-2 might be large and meticulous enough to determine the appropriate timing of intervention for patients with severe AS in contemporary clinical practice.

Impact of Smoking Status on Growth Differentiation Factor 15 and Mortality in Patients With Suspected or Known Coronary Artery Disease: The ANOX Study.

Background Whether circulating growth differentiation factor 15 (GDF-15) levels differ according to smoking status and whether smoking modifies the relationship between GDF-15 and mortality in patients with coronary artery disease are unclear. Methods and Results Using data from a multicenter, prospective cohort of 2418 patients with suspected or known coronary artery disease, we assessed the association between smoking status and GDF-15 and the impact of smoking status on the association between GDF-15 and all-cause death. GDF-15 was measured in 955 never smokers, 1035 former smokers, and 428 current smokers enrolled in the ANOX Study (Development of Novel Biomarkers Related to Angiogenesis or Oxidative Stress to Predict Cardiovascular Events). Patients were followed up during 3 years. The age of the patients ranged from 19 to 94 years; 67.2% were men. Never smokers exhibited significantly lower levels of GDF-15 compared with former smokers and current smokers. Stepwise multiple linear regression analysis revealed that the log-transformed GDF-15 level was independently associated with both current smoking and former smoking. In the entire patient cohort, the GDF-15 level was significantly associated with all-cause death after adjusting for potential clinical confounders. This association was still significant in never smokers, former smokers, and current smokers. However, GDF-15 provided incremental prognostic information to the model with potential clinical confounders and the established cardiovascular biomarkers in never smokers, but not in current smokers or in former smokers. Conclusions Not only current, but also former smoking was independently associated with higher levels of GDF-15. The prognostic value of GDF-15 on mortality was most pronounced in never smokers among patients with suspected or known coronary artery disease.

Distinct Characteristics of VEGF-D and VEGF-C to Predict Mortality in Patients With Suspected or Known Coronary Artery Disease.

Background VEGF-D (vascular endothelial growth factor D) and VEGF-C are secreted glycoproteins that can induce lymphangiogenesis and angiogenesis. They exhibit structural homology but have differential receptor binding and regulatory mechanisms. We recently demonstrated that the serum VEGF-C level is inversely and independently associated with all-cause mortality in patients with suspected or known coronary artery disease. We investigated whether VEGF-D had distinct relationships with mortality and cardiovascular events in those patients. Methods and Results We performed a multicenter, prospective cohort study of 2418 patients with suspected or known coronary artery disease undergoing elective coronary angiography. The serum level of VEGF-D was measured. The primary outcome was all-cause death. The secondary outcomes were cardiovascular death and major adverse cardiovascular events defined as a composite of cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke. During the 3-year follow-up, 254 patients died from any cause, 88 died from cardiovascular disease, and 165 developed major adverse cardiovascular events. After adjustment for possible clinical confounders, cardiovascular biomarkers (N-terminal pro-B-type natriuretic peptide, cardiac troponin-I, and high-sensitivity C-reactive protein), and VEGF-C, the VEGF-D level was significantly associated with all-cause death and cardiovascular death but not with major adverse cardiovascular events.. Moreover, the addition of VEGF-D, either alone or in combination with VEGF-C, to the model with possible clinical confounders and cardiovascular biomarkers significantly improved the prediction of all-cause death but not that of cardiovascular death or major adverse cardiovascular events. Consistent results were observed within patients over 75 years old. Conclusions In patients with suspected or known coronary artery disease undergoing elective coronary angiography, an elevated VEGF-D value seems to independently predict all-cause mortality.

Spontaneous coronary artery dissection in a woman undergoing pseudomenopause therapy with leuprorelin: A case report.

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. SCAD frequently affects women, and may be associated with pregnancy and the peripartum period. Therefore, female sex hormones are thought to play a pathogenetic role. Although pseudomenopause therapy may alter female sex hormone levels similar to those during pregnancy, there are no reported cases of SCAD associated with pseudomenopause therapy. We report the case of a 48-year-old woman who developed SCAD while undergoing pseudomenopause therapy with leuprorelin. This case suggests an association between SCAD and pseudomenopause therapy with leuprorelin. .

Prognostic Impact of Aortic Valve Area in Conservatively Managed Patients With Asymptomatic Severe Aortic Stenosis With Preserved Ejection Fraction.

Background Data are scarce on the role of aortic valve area (AVA) to identify those patients with asymptomatic severe aortic stenosis (AS) who are at high risk of adverse events. We sought to explore the prognostic impact of AVA in asymptomatic patients with severe AS in a large observational database. Methods and Results Among 3815 consecutive patients with severe AS enrolled in the CURRENT AS (Contemporary Outcomes After Surgery and Medical Treatment in Patients With Severe Aortic Stenosis) registry, the present study included 1309 conservatively managed asymptomatic patients with left ventricular ejection fraction ≥50%. The study patients were subdivided into 3 groups based on AVA (group 1: AVA >0.80 cm2, N=645; group 2: 0.8 cm2 ≥AVA >0.6 cm2, N=465; and group 3: AVA ≤0.6 cm2, N=199). The prevalence of very severe AS patients (peak aortic jet velocity ≥5 m/s or mean aortic pressure gradient ≥60 mm Hg) was 2.0%, 5.8%, and 26.1% in groups 1, 2, and 3, respectively. The cumulative 5-year incidence of AVR was not different across the 3 groups (39.7%, 43.7%, and 39.9%; P=0.43). The cumulative 5-year incidence of the primary outcome measure (a composite of aortic valve-related death or heart failure hospitalization) was incrementally higher with decreasing AVA (24.1%, 29.1%, and 48.1%; P<0.001). After adjusting for confounders, the excess risk of group 3 and group 2 relative to group 1 for the primary outcome measure remained significant (hazard ratio, 2.21, 95% CI, 1.56-3.11, P<0.001; and hazard ratio, 1.34, 95% CI, 1.01-1.78, P=0.04, respectively). Conclusions AVA ≤0.6 cm2 would be a useful marker to identify those high-risk patients with asymptomatic severe AS, who might benefit from early AVR. Clinical Trial Registration URL: www.umin.ac.jp .

Causes of death in Japanese patients with atrial fibrillation: The Fushimi Atrial Fibrillation Registry.

Aims: To investigate the causes of death and the associated clinical factors in patients with atrial fibrillation (AF) in the contemporary clinical practice. Methods and results: The Fushimi AF Registry is a community-based prospective survey of AF patients since March 2011 in Fushimi-ku, Kyoto. We investigated causes of death and the clinical indicators of cardiovascular (CV) and non-CV death in 4045 patients with available follow-up data by the end of November 2016. The mean age was 73.6 ± 10.9 years and the mean CHA2DS2-VASc score was 3.38 ± 1.69. Oral anticoagulants were prescribed in 55% of patients. During a median follow-up of 1105 days, there were 705 all-cause deaths (5.5%/year); 180 CV (26% of total deaths), 381 non-CV (54%), and 144 undetermined causes (20%). The most common causes of CV and non-CV death were heart failure (14.5%), malignancy (23.1%), and infection/sepsis (17.3%), while mortality due to stroke was only 6.5%. Mortality due to infection/sepsis and undetermined causes increased with aging. On multivariate analysis, the strongest indicator of CV death was pre-existing heart failure [hazard ratio (HR) 2.42, 95% confidence interval (CI) 1.66-3.54; P < 0.001] and that of non-CV death was anaemia (HR 2.84, 95% CI 2.22-3.65; P < 0.001). Conclusion: In a Japanese community-based AF cohort, CV death was not mainly related to stroke but to heart failure. Non-CV death, mainly malignancy and infection, comprised more than a half of all deaths, which increased substantially in accordance with aging. Clinical factors that were associated with CV and non-CV death were distinct.

B-type natriuretic peptide in patients with asymptomatic severe aortic stenosis.

OBJECTIVES: We sought to evaluate the prognostic impact of the B-type natriuretic peptide (BNP) levels in patients with asymptomatic severe aortic stenosis (AS), who were not referred for aortic valve replacement (AVR). METHODS: We used data from a Japanese multicentre registry, the Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis Registry, which enrolled 3815 consecutive patients with severe AS. Of those, 387 asymptomatic patients who were not referred for AVR without left ventricular dysfunction and very severe AS were subdivided into four groups based on their BNP levels (BNP<100 pg/mL, n=201; 100≤BNP<200 pg/mL, n=94; 200≤BNP<300 pg/mL, n=42 and BNP>300 pg/mL, n=50). RESULTS: The cumulative 5-year incidence of AS-related events (aortic valve-related death or heart failure hospitalisation) was incrementally higher with increasing BNP level (14.2%, 29.6%, 46.3% and 47.0%, p<0.001). After adjusting for confounders, the risk for AS-related events was incrementally greater with increasing BNP levels (HR: 1.97, 95% CI: 0.97 to 3.98, p=0.06; HR: 3.59, 95% CI: 1.55 to 8.32, p=0.03 and HR: 7.38, 95% CI: 3.21 to 16.9, p<0.001, respectively). Notably, asymptomatic patients with BNPlevels of <100 pg/mL had an event rate of only 2.1% at 1 year. CONCLUSIONS: Increased BNP level was associated with a higher risk for AS-related adverse events in patients with asymptomatic severe AS with normal left ventricular ejection fraction who were not referred for AVR. Asymptomatic patients with BNP levels of <100 pg/mL had relatively low event rate, who might be safely followed with watchful waiting strategy. TRAIL REGISTRATION NUMBER: UMIN000012140.

Causes of Death in Patients with Severe Aortic Stenosis: An Observational study.

Whether patients with severe aortic stenosis (AS) die because of AS-related causes is an important issue for the management of these patients. We used data from CURRENT AS registry, a Japanese multicenter registry, to assess the causes of death in severe AS patients and to identify the factors associated with non-cardiac mortality. We enrolled 3815 consecutive patients with a median follow-up of 1176 days; the 1449 overall deaths comprised 802 (55.3%) from cardiac and 647 (44.7%) from non-cardiac causes. Heart failure (HF) (25.7%) and sudden death (13.0%) caused the most cardiac deaths, whereas infection (13.0%) and malignancy (11.1%) were the main non-cardiac causes. According to treatment strategies, infection was the most common cause of non-cardiac death, followed by malignancy, in both the initial aortic valve replacement (AVR) cohort (N = 1197), and the conservative management cohort (N = 2618). Both non-cardiac factors (age, male, body mass index <22, diabetes, prior history of stroke, dialysis, anemia, and malignancy) and cardiac factors (atrial fibrillation, ejection fraction <68%, and the initial AVR strategy) were associated with non-cardiac death. These findings highlight the importance of close monitoring of non-cardiac comorbidities, as well as HF and sudden death, to improve the mortality rate of severe AS patients.

Impact of Transient or Persistent Contrast-induced Nephropathy on Long-term Mortality After Elective Percutaneous Coronary Intervention.

Contrast-induced nephropathy (CIN) is associated with increased long-term mortality. However, it is still controversial whether CIN is the cause of increased mortality or merely a marker of high-risk patients. The current study population included 5,516 patients who underwent their first elective percutaneous coronary intervention (PCI) in the Coronary REvascularization Demonstrating Outcome Study in Kyoto registry cohort-2. CIN was defined as an elevation in the peak serum creatinine (SCr) of ≥0.5 mg/dl from the baseline within 5 days after PCI. CIN, seen in 218 patients (4.0%), was independently associated with an increased long-term mortality risk (hazard ratio [HR] 1.43, 95% confidence interval [CI],1.11 to 1.83; p = 0.005). SCr data at 1 year (180 to 550 days) after PCI were available in 3,986 patients, who were subdivided into persistent CIN (follow-up SCr elevation ≥0.5 mg/dl: n = 50 [1.3%]), transient CIN (follow-up SCr elevation <0.5 mg/dl: n = 90 [2.3%]), and non-CIN (n = 3,846 [96.5%]). In the landmark analysis at 1 year after PCI, 524 patients (13.1%) died during a median follow-up of 1,521 days. After adjustment for the 37 confounders, persistent CIN, but not transient CIN, was significantly correlated with a higher long-term mortality risk compared with non-CIN (HR 1.84, 95% CI 1.12 to 3.03; p = 0.02, and HR 1.11, 95% CI 0.71 to 1.76; p = 0.6, respectively). In conclusion, only persistent CIN was independently associated with increased long-term mortality.

Prognostic Impact of Peak Aortic Jet Velocity in Conservatively Managed Patients With Severe Aortic Stenosis: An Observation From the CURRENT AS Registry.

BACKGROUND: There are limited data regarding the risk stratification based on peak aortic jet velocity (Vmax) in patients with severe aortic stenosis (AS). METHODS AND RESULTS: Among 3815 consecutive patients with severe AS enrolled in the CURRENT AS (Contemporary Outcomes After Surgery and Medical Treatment in Patients With Severe Aortic Stenosis) registry, the study population consisted of 1075 conservatively managed patients with Vmax ≥4.0 m/s and left ventricular ejection fraction ≥50%. The study patients were subdivided into 3 groups based on Vmax (group 1, 4.0 ≤ Vmax <4.5 m/s, N=550; group 2, 4.5 ≤ Vmax <5 m/s, N=279; and group 3, Vmax ≥5 m/s, N=246). Cumulative 5-year incidence of AS-related events (aortic valve-related death or heart failure hospitalization) was incrementally higher with increasing Vmax (entire population; 38.0%, 49.4%, and 62.8%, P<0.001; symptomatic patients; 55.7%, 60.9%, and 72.2%, P=0.008; and asymptomatic patients; 29.4%, 38.9%, and 47.7%, P=0.005). After adjusting for confounders, the excess risk of group 2 and group 3 relative to group 1 for AS-related events remained significant (hazard ratio, 1.39; 95% CI, 1.07-1.81; P=0.02, and hazard ratio, 1.53; 95% CI, 1.17-2.00; P=0.002, respectively). The effect size of group 3 relative to group 1 for AS-related events in asymptomatic patients (N=479) was similar to that in symptomatic patients (N=596; hazard ratio, 1.59; 95% CI, 1.01-2.52; P=0.047, and hazard ratio, 1.67; 95% CI, 1.16-2.40, P=0.008, respectively), and there was no significant overall interaction between the symptomatic status and the effect of the Vmax categories on AS-related events (interaction, P=0.88). CONCLUSIONS: In conservatively managed severe AS patients with preserved left ventricular ejection fraction, increasing Vmax was associated with incrementally higher risk for AS-related events. However, the cumulative 5-year incidence of the AS-related events remained very high even in asymptomatic patients with less greater Vmax.

High- Versus Low-Gradient Severe Aortic Stenosis: Demographics, Clinical Outcomes, and Effects of the Initial Aortic Valve Replacement Strategy on Long-Term Prognosis.

BACKGROUND: There is considerable debate on the management of patients with low-gradient severe aortic stenosis (LG-AS), defined as aortic valve area <1 cm2 with peak aortic jet velocity ≤4.0 m/s, and mean aortic pressure gradient ≤40 mm Hg. METHODS AND RESULTS: In the CURRENT AS registry (Contemporary Outcomes After Surgery and Medical Treatment in Patients With Severe Aortic Stenosis), there were 2097 patients (initial aortic valve replacement [AVR] strategy: n=977, and conservative strategy: n=1120) with high-gradient severe aortic stenosis (HG-AS) and 1712 patients (initial AVR strategy: n=219, and conservative strategy: n=1493) with LG-AS. AVR was more frequently performed in HG-AS patients than in LG-AS patients (60% versus 28%) during the entire follow-up. In the comparison between the initial AVR and conservative groups, the propensity score-matched cohorts were developed in both HG-AS (n=887 for each group) and LG-AS (n=218 for each group) strata. The initial AVR strategy when compared with the conservative strategy was associated with markedly lower risk for a composite of aortic valve-related death or heart failure hospitalization in both HG-AS and LG-AS strata (hazard ratio, 0.30; 95% confidence interval, 0.25-0.37; P<0.001 and hazard ratio, 0.46; 95% confidence interval, 0.32-0.67; P<0.001, respectively). Among 1358 patients with LG-AS with preserved left ventricular ejection fraction, the initial AVR strategy was associated with a better outcome than the conservative strategy (adjusted hazard ratio, 0.37; 95% confidence interval, 0.23-0.59; P<0.001). CONCLUSIONS: The initial AVR strategy was associated with better outcomes than the conservative strategy in both HG-AS and LG-AS patients, although AVR was less frequently performed in LG-AS patients than in HG-AS patients. The favorable effect of initial AVR strategy was also seen in patients with LG-AS with preserved left ventricular ejection fraction.

Relation of Stroke and Major Bleeding to Creatinine Clearance in Patients With Atrial Fibrillation (from the Fushimi AF Registry).

Creatinine clearance (CrCl) has been widely used to adjust the dosage of non-vitamin K antagonist oral anticoagulants in patients with atrial fibrillation (AF) and exclude contraindicated patients. However, there are few available real-world data on the relation between CrCl and adverse clinical outcomes in patients with AF. Therefore, we evaluated the clinical characteristics and adverse events in Japanese patients with AF stratified by CrCl. We categorized patients in the Fushimi AF Registry, a large prospective community-based Japanese cohort of patients with AF, into 3 groups as follows: (1) CrCl <30 ml/min, (2) CrCl 30 to 49 ml/min, and (3) CrCl ≥50 ml/min. We evaluated 3,080 patients after a median follow-up of 1,076 days. Comparing with patients with CrCl ≥50 ml/min, patients with AF with CrCl <30 ml/min showed increased risks of stroke/systemic embolism (SE) (hazard ratio [HR] 1.68; 95% confidence interval [CI] 1.04 to 2.65; p = 0.04) and major bleeding (HR, 2.08; 95% CI 1.23 to 3.39; p = 0.008) after adjustment for prespecified factors. Patients with AF with CrCl <30 ml/min were also associated with higher risks of all-cause death, hospitalization for heart failure, myocardial infarction, or the composite of all-cause death and stroke/SE. However, no excess risk of stroke/SE (HR 1.10; 95% CI 0.76 to 1.58; p = 0.6) or major bleeding (HR 0.98; 95% CI 0.63 to 1.48; p = 0.9) was noted for patients with CrCl 30 to 49 ml/min. In conclusion, Japanese patients with AF with CrCl <30 ml/min were closely associated with adverse clinical events including stroke/SE and major bleeding.

Initial Surgical Versus Conservative Strategies in Patients With Asymptomatic Severe Aortic Stenosis.

BACKGROUND: Current guidelines generally recommend watchful waiting until symptoms emerge for aortic valve replacement (AVR) in asymptomatic patients with severe aortic stenosis (AS). OBJECTIVES: The study sought to compare the long-term outcomes of initial AVR versus conservative strategies following the diagnosis of asymptomatic severe AS. METHODS: We used data from a large multicenter registry enrolling 3,815 consecutive patients with severe AS (peak aortic jet velocity >4.0 m/s, or mean aortic pressure gradient >40 mm Hg, or aortic valve area <1.0 cm(2)) between January 2003 and December 2011. Among 1,808 asymptomatic patients, the initial AVR and conservative strategies were chosen in 291 patients, and 1,517 patients, respectively. Median follow-up was 1,361 days with 90% follow-up rate at 2 years. The propensity score-matched cohort of 582 patients (n = 291 in each group) was developed as the main analysis set for the current report. RESULTS: Baseline characteristics of the propensity score-matched cohort were largely comparable, except for the slightly younger age and the greater AS severity in the initial AVR group. In the conservative group, AVR was performed in 41% of patients during follow-up. The cumulative 5-year incidences of all-cause death and heart failure hospitalization were significantly lower in the initial AVR group than in the conservative group (15.4% vs. 26.4%, p = 0.009; 3.8% vs. 19.9%, p < 0.001, respectively). CONCLUSIONS: The long-term outcome of asymptomatic patients with severe AS was dismal when managed conservatively in this real-world analysis and might be substantially improved by an initial AVR strategy.

[Mycotic aortic aneurysm due to Streptococcus pneumoniae: a case report and review of literature].

Mycotic aortic aneurysm due to Streptococcus pneumoniae is rare. The case of we report occurred in 62-year-old man with no antecedent infection admitted for appetite loss and lower leg edema. Chest and abdominal computed tomography, blood culture, and gene analysis to detec arterial wall pneumococci led to a diagnosis of mycotic aortic aneurysm caused by S. pneumoniae. The man had a graft replaced and was administered antibiotics. He remains well and infection-free 12 months after surgery. We also review the literature on these aortic aneurysms.

Bare metal stent implantation in large-sized unprotected left main coronary artery stenosis in the drug-eluting stent era.

Recently, drug-eluting stent (DES) has been recommended as the first choice in those patients who need stent implantation in unprotected left main coronary artery (ULMCA) stenosis. However, the long-term safety and efficacy of this procedure is still controversial. The objective of this study was to evaluate the safety and efficacy of bare metal stent (BMS) implantation in ULMCA stenting in the DES era. We implanted BMS (mainly 4 mm-diameter) in large-sized ULMCA after December 2004 when DES became available. The results of BMS implantation (n = 19) were compared with those of DES implantation (n = 39). There was no significant difference between the 2 groups regarding age, gender and coronary risk factors. Emergency procedures were more frequently performed in the BMS group than in the DES group (53% vs. 26%, p = 0.08). The initial mortality was 10.5% (n = 2) in the BMS group and 2.6% (n = 1) in the DES group (p = 0.25). There was no stent thrombosis, Q-wave myocardial infarction or emergent bypass surgery in either group during their hospital stay. The restenosis rate was 0% (n = 45) in both groups, and the target vessel revascularization rate was 5.9% in the BMS group (1/17) and 2.6% (1/38) in the DES group (p = 0.53). Therefore, there were no statistically significant differences in outcomes between the two study groups. These results indicate that BMS implantation in a large-sized ULMCA may be a safe and effective treatment even in the DES era.
