RESUMO
We report a case of a 63-year-old woman diagnosed with vascular Ehlers-Danlos syndrome (vEDS) who survived two prophylactic surgeries for the dilatation of a thoracoabdominal aortic aneurysm. She initially developed acute type B aortic dissection at the age of 44â¯years. Five years later, her dissected descending aorta was enlarged to 54â¯mm; thus, the descending aorta was replaced as the first surgery. Fortunately, the intra- and post-operative courses were uneventful. Fourteen years post her first surgery, the dissected thoracoabdominal aorta distal to the graft expanded to 53â¯mm; however, no anastomotic leakage was observed. Genetic testing revealed a COL3A1 abnormality, confirming the diagnosis of vEDS. Thoracoabdominal aorta replacement using deep hypothermia circulatory arrest was performed because of the high risk of aortic aneurysm rupture. The second surgery was performed without complications, and no complications were observed 13â¯months post-surgery. The major reason for a successful surgery in this patient was the relatively low vascular fragility associated with vEDS. This case demonstrates that there may be considerable individual differences in vascular fragility in patients with vEDS. Thus, surgical repair, along with endovascular therapy, might still be a beneficial option for patients with vEDS having large aortic aneurysms and a high risk of rupture. Learning objective: Prophylactic surgery for vascular lesions in Ehlers-Danlos syndrome (vEDS) is generally not recommended because of its high vascular fragility. However, if a patient with vEDS has an aortic aneurysm that is at a very high risk of rupture, aggressive treatment is a plausible option as there may be considerable individual differences in vascular fragility among patients with vEDS.
RESUMO
BACKGROUND: Epidemiological data on ruptured aortic aneurysms from large-scale studies are scarce. The aims of this study were to: clarify the clinical course of ruptured aortic aneurysms; identify aneurysm site-specific therapies and outcomes; and determine the clinical course of patients receiving conservative therapy.MethodsâandâResults: Using the Tokyo Acute Aortic Super Network database, we retrospectively analyzed 544 patients (mean [±SD] age 78±10 years; 70% male) with ruptured non-dissecting aortic aneurysms (AAs) after excluding those with impending rupture. Patient characteristics, status on admission, therapeutic strategy, and outcomes were evaluated. Shock or pulselessness on admission were observed in 45% of all patients. Conservative therapy, endovascular therapy (EVT), and open surgery (OS) accounted for 32%, 23%, and 42% of cases, respectively, with corresponding mortality rates of 93%, 30%, and 29%. The overall in-hospital mortality rate was 50%. The prevalence of pulselessness was highest (48%) in the ruptured ascending AA group, and in-hospital mortality was the highest (70%) in the ruptured thoracoabdominal AA group. Multivariable logistic regression analysis indicated in-hospital mortality was positively associated with pulselessness (odds ratio [OR] 10.12; 95% confidence interval [CI] 4.09-25.07), and negatively associated with invasive therapy (EVT and OS; OR 0.11; 95% CI 0.06-0.20). CONCLUSIONS: The outcomes of ruptured AAs remain poor; emergency invasive therapy is essential to save lives, although it remains challenging to reduce the risk of death.
RESUMO
OBJECTIVE: To determine the status of type A acute aortic dissection using the Tokyo Acute Aortic Super Network. METHODS: Data of 6283 patients with acute aortic dissection between 2015 and 2019 were collected. Data of 3303 patients with type A acute aortic dissection were extracted for analysis. RESULTS: Overall, 51.0% of patients were nondirect admissions. On arrival, 23.1% of patients were in shock, 10.0% in cardiopulmonary arrest, and 11.8% in deep coma or coma. Overall, 9.8% of patients were assessed as untreatable. Of 2979 treatable patients, 18.3% underwent medical treatment, whereas 80.7% underwent surgery (open [78.8%], endovascular [1.9%], and peripheral [1.1%] repair). The early mortality rate was 20.5%, including untreatable cases. Among treatable patients, in-hospital mortality rates were 8.6% for open repair, 10.7% for endovascular repair, and 25.3% for medical treatment. Advanced age, preoperative comorbidities, classical dissection, and medical treatment were risk factors for in-hospital mortality. Nondirect admission did not cause increased deaths. The mortality rates were high during the superacute phase following symptom onset. CONCLUSIONS: This study demonstrated current practices in the emergency care of type A acute aortic dissection via the Tokyo Acute Aortic Super Network system, specifically a high rate of untreatable or inoperable cases and favorable outcomes in patients undergoing surgical treatment. High mortality rates were observed during the super acute phase after symptom onset or hospital arrival.

This retrospective observational study aimed to examine the relationships of maximum walking speed (MWS) with peak oxygen uptake (peak VO2) and anaerobic threshold (AT) obtained by cardiopulmonary exercise testing (CPX) in patients with heart failure. The study participants were 104 consecutive men aged ≥ 20 years who had been hospitalized or had undergone outpatient care at our hospital for heart failure between February 2019 and January 2023. MWS was measured in a 5-m section with a 1-m run-up before and after the course. Multivariable analysis was used to examine the association between MWS and peak VO2 and AT by CPX. The Pearson correlation coefficient showed that MWS was positively correlated with percent-predicted peak VO2 and percent-predicted AT (r = 0.463, p < 0.001; and r = 0.485, p < 0.001, respectively). In the multiple linear regression analysis employing percent-predicted peak VO2 and percent-predicted AT as the objective variables, only MWS demonstrated a significant positive correlation (standardized ß: 0.471, p < 0.001 and 0.362, p < 0.001, respectively). Multiple logistic regression analyses, using an 80% cutoff in percent-predicted peak VO2 and AT, revealed that only MWS was identified as a significant factor in both cases (odds ratio [OR]: 1.239, 95% confidence interval [CI]: 1.071-1.432, p = 0.004 and OR: 1.469, 95% CI: 1.194-1.807, p < 0.001, respectively). MWS was correlated with peak VO2 and AT in male patients with heart failure. The MWS measurement as a screening test for exercise tolerance may provide a simple means of estimating peak VO2 and AT in heart failure patients.

Although the primary percutaneous coronary intervention (PCI) is an established treatment for acute ST-elevation myocardial infarction (STEMI), relevant guidelines do not recommend it for recent-STEMI cases with a totally occluded infarcted related artery (IRA). However, PCI is allowed in Japan for recent-STEMI cases, but little is known regarding its outcomes. We aimed to examine the details and outcomes of PCI procedures in recent-STEMI cases with a totally occluded IRA and compared the findings with those in acute-STEMI cases.Among the 903 consecutive patients admitted with acute coronary syndrome, 250 were treated with PCI for type I STEMI with a totally occluded IRA. According to the time between symptom onset and diagnosis, patients were divided into the recent-STEMI (n = 32) and acute-STEMI (n = 218) groups. The background, procedure details, and short-term outcomes were analyzed. No significant differences between the groups were noted regarding patient demographics, acute myocardial infarction severity, or IRA distribution. Although the stent number and type were similar, significant differences were observed among PCI procedures, including the number of guidewires used, rate of microcatheter or double-lumen catheter use, and application rate of thrombus aspiration. The thrombolysis rate in the myocardial infarction flow 3-grade post-PCI did not differ significantly between the groups. Both groups had a low frequency of procedure-related complications. The in-hospital mortality rates were 0% and 4.6% in the recent-STEMI and acute-STEMI groups, respectively (P > 0.05).Although recent-STEMI cases required complicated PCI techniques, their safety, success rate, and in-hospital mortality were comparable to those of acute-STEMI cases.

Patients with acute myocardial infarction (AMI) triaged as life-threatening are transferred to our emergency medical care center (EMCC). However, data on these patients remain limited. We aimed to compare the characteristics and AMI prognosis of patients transferred to our EMCC with those transferred to our cardiovascular intensive care unit (CICU) using whole and propensity-matched cohorts.We analyzed the data of 256 consecutive AMI patients transferred from the scene to our hospital by ambulance between 2014 and 2017. The EMCC and CICU groups comprised 77 and 179 patients, respectively. There were no significant between-group age or sex differences. Patients in the EMCC group had more disease severity score and had the left main trunk identified as the culprit more frequently (12% versus 0.6%, P < 0.001) than those in the CICU group; however, the number of patients with multiple culprit vessels did not differ. The EMCC group had a longer door-to-reperfusion time (75 [60, 109] minutes versus 60 [40, 86] minutes, P< 0.001) and a higher in-hospital mortality (19% versus 4.5%, P < 0.001), especially from non-cardiac causes (10% versus 0.6%, P < 0.001), than the CICU group. However, peak myocardial creatine phosphokinase did not significantly differ between the groups. The EMCC group had a significantly higher 1-year post-discharge mortality than the CICU group (log-rank, P = 0.032); this trend was maintained after propensity score matching, although the difference was not statistically significant (log-rank, P = 0.094).AMI patients transferred to the EMCC exhibited more severe disease and worse overall in-hospital and non-cardiac mortality than those transferred to the CICU.

OBJECTIVES: Preventing loss of life in patients with type A acute aortic dissection (AAD) who present with cardiopulmonary arrest (CPA) can be extremely difficult. Thus, we investigated the early outcomes in these patients. METHODS: Patients with type A AAD who were transported to hospitals belonging to the Tokyo Acute Aortic Super-network between January 2015 and December 2019 were considered for this study. We assessed the early mortality of these patients presenting with CPA and also investigated the differences in outcomes between patients with out-of-hospital and in-hospital CPA. RESULTS: A total of 3307 patients with type A AAD were transported, 434 (13.1%) of whom presented with CPA. The overall mortality of patients presenting with CPA was 88.2% (383/434), of which 94.5% (240/254) experienced out-of-hospital CPA and 79.4% (143/180) experienced in-hospital CPA (P < 0.001). Multivariable analysis revealed that aortic surgery [odds ratio (OR), 0.022; 95% confidence interval (CI), 0.008-0.060; P < 0.001] and patient age over 80 years (OR, 2.946; 95% CI, 1.012-8.572; P = 0.047) were related with mortality in patients with type A AAD and CPA. Between in-hospital and out-of-hospital CPA, the proportions of DeBakey type 1 (OR, 2.32; 95% CI, 1.065-5.054; P = 0.034), cerebral malperfusion (OR, 0.188; 95% CI, 0.056-0.629; P = 0.007), aortic surgery (OR, 0.111; 95% CI, 0.045-0.271; P = 0.001), age (OR, 0.969; 95% CI, 0.940-0.998; P = 0.039) and the time from symptom onset to hospital admission (OR, 1.122; 95% CI, 1.025-1.228; P = 0.012) were significantly different. CONCLUSIONS: Patients with type A AAD presenting with CPA exhibited extremely high rates of death. Patient outcomes following in-hospital CPA tended to be better than those following out-of-hospital CPA; however, this difference was not significantly different. To prevent deaths, aortic surgery, when possible, should be considered in patients with type A AAD who sustained CPA.

Background: Vascular Ehlers-Danlos syndrome (vEDS) is a rare disorder with poor prognosis, owing to associated vascular complications. However, the most prevalent arterial problems in patients with vEDS are not well known. Methods: We retrospectively examined 20 consecutive patients diagnosed with vEDS and examined their clinical events, image findings, and therapies. Results: The age at first complication requiring admission was 29 ± 13 years. The observational period was 67 ± 30 months. Of the 20 patients, 17 took celiprolol at final assessment. At the final follow-up, the total number of complications relating to lesions and requiring admission was 16 for pulmonary lesions (8 patients), 16 for bowel lesions (8 patients), 5 for tendon/ligament lesions (2 patients), 18 for the branch arteries of the abdominal aorta (10 patients), 2 for the aorta (2 patients), and 7 for other arteries (6 patients). Of 54 arterial involvements (aneurysms, dissections, and ruptures), both with and without symptoms, 43 (80%) were in branches of the abdominal aorta (celiac artery and branches, 8; superior mesenteric artery, 4; renal arteries, 3; iliac arteries and branches, 28), 2 (4%) were in the aorta, and 9 were in other arteries. The diameter of the sinus of Valsalva was 29 ± 5 mm, within the normal range. During follow-up, 3 patients died due to suspected ruptures in a branch of the celiac artery, the superior mesenteric artery, and the aorta. Conclusion: Our findings indicate that lesions involving the branch arteries of the abdominal aorta, rather than aorta, were the most prevalent lesion type in patients with vEDS.
Contexte: Le syndrome d'Ehlers-Danlos vasculaire (SEDv) est une affection rare au pronostic sombre en raison des complications vasculaires qui y sont associées. Toutefois, les problèmes artériels les plus fréquents chez les patients atteints de SEDv sont mal connus. Méthodologie: Nous avons analysé de manière rétrospective les cas de 20 patients consécutifs ayant reçu un diagnostic de SEDv. Les données relatives aux manifestations cliniques, les résultats des examens d'imagerie et les traitements prescrits ont été examinés. Résultats: L'âge auquel la première complication nécessitant une hospitalisation est survenue était de 29 ± 13 ans. La période d'observation était de 67 ± 30 mois. Parmi ces 20 patients, 17 recevaient du céliprolol lors de l'évaluation finale. Lors de la dernière visite de suivi, le nombre total de complications associées aux lésions et ayant nécessité une hospitalisation comprenaient : 16 lésions pulmonaires (8 patients), 16 lésions intestinales (8 patients), 5 lésions tendineuses ou ligamentaires (2 patients), 18 complications touchant les ramifications (artères) de l'aorte abdominale (10 patients), 2 complications aortiques (2 patients) et 7 complications d'autres artères (6 patients). Sur les 54 atteintes artérielles (anévrismes, dissections et ruptures), qu'elles aient été symptomatiques ou pas, 43 (80 %) concernaient des ramifications de l'aorte abdominale (artère cÅliaque et ses ramifications, 8; artère mésentérique supérieure, 4; artères rénales, 3; artère iliaque et ses ramifications, 28), 2 (4 %) concernaient l'aorte, et 9, d'autres artères. Le diamètre du sinus de Valsalva était de 29 ± 5 mm, soit dans les limites de la normale. Au cours de la période de suivi, 3 patients sont décédés en raison de ruptures suspectées d'une ramification de l'artère cÅliaque, de l'artère mésentérique supérieure et de l'aorte. Conclusion: Les résultats de nos analyses indiquent que les lésions touchant des ramifications de l'aorte abdominale, plutôt que de l'aorte elle-même, étaient les types de lésions les plus fréquents chez les patients atteints de SEDv.
RESUMO
Background: Sex differences in the clinical presentation and outcomes of DeBakey type I/II (Stanford type A) acute aortic dissection (AAD) remain unclear. Objectives: The authors aimed to determine the impact of sex on the clinical presentation and in-hospital outcomes of surgically or medically treated patients with type I/II AAD. Methods: We studied 3,089 patients with type I/II AAD enrolled in multicenter Japanese registry between 2013 and 2018. The patients were divided into 2 treatment groups: surgical and medical. Multivariable logistic regression was used to examine the association between sex and in-hospital mortality. Results: In the entire cohort, women were older and more likely to have hyperlipidemia, previous stroke, altered consciousness, and shock/hypotension at presentation than men. Women had higher proportions of intramural hematomas and type II dissections than men. In the surgical group (n = 2,543), men had higher rates of preoperative end-organ malperfusion (P = 0.003) and in-hospital mortality (P = 0.002) than women. Multivariable analysis revealed that male sex was associated with higher in-hospital mortality after surgery (OR: 1.71; 95% CI: 1.24-2.35; P < 0.001). In the medical group (n = 546), women were older and had higher rates of cardiac tamponade (P = 0.004) and in-hospital mortality (P = 0.039) than men; no significant association between sex and in-hospital mortality was found after multivariable adjustment (OR: 0.95; 95% CI: 0.56-1.59; P = 0.832). Conclusions: Male sex was associated with higher in-hospital mortality for type I/II AAD in the surgical group but not in the medical group. Further research is needed to understand the mechanisms responsible for worse surgical outcomes in men.
RESUMO
Background: In acute aortic dissection, weekend admissions are reported to be associated with increased mortality compared with weekday admissions. Objective: This study aimed to determine whether patients with acute type A aortic dissection (ATAAD) admitted on weekends had higher in-hospital mortality than those admitted on weekdays in the Tokyo metropolitan area, where we developed a patient-transfer system for aortic dissection. Methods: Data were collected during the first year after our transfer system began (cohort I) and in the subsequent years from 2013 to 2015 (cohort II). Results: We studied 2,339 patients (500 in cohort I; 1,839 in cohort II) with ATAAD. Patients with weekend admissions had higher in-hospital mortality than those with weekday admissions in cohort I. In association with increased interfacility transfer during weekends and reduced mortality at non-high-volume centers, the in-hospital mortality in the weekend group improved from 37.2% in cohort I to 22.2% in cohort II (P < 0.001). After inverse probability weighting adjustment, weekend admission was associated with higher in-hospital mortality in cohort I (odds ratio: 2.28; 95% confidence interval: 1.48 to 3.52; P < 0.001), but not in cohort II (odds ratio: 0.96; 95% confidence interval: 0.75 to 1.22; P = 0.731). On multivariable analyses, weekend admission was associated with higher in-hospital mortality in combined cohort I+II; the associations between weekend admission and mortality were not significant in cohort II. Conclusions: We found a significant reduction in in-hospital mortality in patients with weekend admissions for ATAAD. No mortality difference between weekend and weekday admissions was observed in the later years of the study.
RESUMO
Background The association between female sex and poor outcomes following surgery for type A acute aortic dissection has been reported; however, sex-related differences in clinical features and in-hospital outcomes of type B acute aortic dissection, including classic aortic dissection and intramural hematoma, remain to be elucidated. Methods and Results We studied 2372 patients with type B acute aortic dissection who were enrolled in the Tokyo Acute Aortic Super-Network Registry. There were fewer and older women than men (median age [interquartile range]: 76 years [66-84 years], n=695 versus 68 years [57-77 years], n=1677; P<0.001). Women presented to the aortic centers later than men. Women had a higher proportion of intramural hematoma (63.7% versus 53.7%, P<0.001), were medically managed more frequently (90.9% versus 86.3%, P=0.002), and had less end-organ malperfusion (2.4% versus 5.7%, P<0.001) and higher in-hospital mortality (5.3% versus 2.7%, P=0.002) than men. In multivariable analysis, age (per year, odds ratio [OR], 1.06 [95% CI, 1.03-1.08]; P<0.001), hyperlipidemia (OR, 2.09 [95% CI, 1.13-3.88]; P=0.019), painlessness (OR, 2.59 [95% CI, 1.14-5.89]; P=0.023), shock/hypotension (OR, 2.93 [95% CI, 1.21-7.11]; P=0.017), non-intramural hematoma (OR, 2.31 [95% CI, 1.32-4.05]; P=0.004), aortic rupture (OR, 26.6 [95% CI, 14.1-50.0]; P<0.001), and end-organ malperfusion (OR, 4.61 [95% CI, 2.11-10.1]; P<0.001) were associated with higher in-hospital mortality, but was not female sex (OR, 1.67 [95% CI, 0.96-2.91]; P=0.072). Conclusions Women affected with type B acute aortic dissection were older and had more intramural hematoma, a lower incidence of end-organ malperfusion, and higher in-hospital mortality than men. However, female sex was not associated with in-hospital mortality after multivariable adjustment.

BACKGROUND: High coronary thrombus burden has been associated with unfavorable outcomes in patients with ST-segment elevation myocardial infarction (STEMI), the optimal management of which has not yet been established. METHODS: We assessed the adjunctive catheter-directed thrombolysis (CDT) during primary percutaneous coronary intervention (PCI) in patients with STEMI and high thrombus burden. CDT was defined as intracoronary infusion of tissue plasminogen activator (t-PA; monteplase). RESULTS: Among the 1849 consecutive patients with STEMI, 263 had high thrombus burden. Moreover, 41 patients received t-PA (CDT group), whereas 222 did not receive it (non-CDT group). No significant differences in bleeding complications and in-hospital and long-term mortalities were observed (9.8% vs. 7.2%, p = 0.53; 7.3% vs. 2.3%, p = 0.11; and 12.6% vs. 17.5%, p = 0.84, CDT vs. non-CDT). In patients who underwent antecedent aspiration thrombectomy during PCI (75.6% CDT group and 87.4% non-CDT group), thrombolysis in myocardial infarction grade 2 or 3 flow rate after thrombectomy was significantly lower in the CDT group than in the non-CDT group (32.2% vs. 61.0%, p < 0.01). However, the final rates improved without significant difference (90.3% vs. 97.4%, p = 0.14). CONCLUSIONS: Adjunctive CDT appears to be tolerated and feasible for high thrombus burden. Particularly, it may be an option in cases with failed aspiration thrombectomy.
RESUMO
Vascular Ehlers-Danlos syndrome (vEDS) causes fatal vascular complications due to vascular fragility. However, invasive therapeutic procedures are generally avoided except in emergencies. We report a case of vEDS presenting with rapid expansion of a hepatic arterial aneurysm successfully treated using prophylactic endovascular therapy. A 43-year-old woman with vEDS confirmed by genetic testing was hospitalized for a symptomatic hepatic arterial aneurysm that expanded rapidly within a week. Prophylactic coil embolization was then successfully performed. Although the general applicability of this approach cannot be determined, prophylactic endovascular therapy can clearly be an option for arterial aneurysms at high risk of rupture.

OBJECTIVES: We investigated the various pre- and postoperative complications related to early (30-day) mortality after open surgery for acute type A aortic dissection. METHODS: Data from the Tokyo Acute Aortic Super-network database spanning January 2015 to December 2017 were retrospectively reviewed. Pre- and postoperative factors related to early postoperative mortality were assessed in 1504 of 2058 (73.0%) consecutive patients [age: 66.6 (SD: 13.5) years, male: 52.9%] who underwent acute type A aortic dissection repair. RESULTS: The early mortality rate following surgical repair was 8.9%. According to multivariable analysis, male sex [odds ratio (OR) 1.670, 95% confidence interval (CI) 1.063-2.624, P = 0.026], use of percutaneous circulatory assist devices (n = 116, 7.7%) including extracorporeal membrane oxygenators or intra-aortic balloon pumps (OR 4.857, 95% CI 2.867-8.228, P < 0.001), shock (n = 162, 10.8%) (OR 3.06, 95% CI 1.741-5.387, P < 0.001), cardiopulmonary arrest (n = 41, 2.7%) (OR 7.534, 95% CI 3.407-16.661, P < 0.001), coronary ischaemia (n = 36, 2.3%) (OR 2.583, 95% CI 1.042-6.404, P = 0.041) and cerebral ischaemia (n = 59, 3.9%) (OR 2.904, 95% CI 1.347-6.261, P = 0.007) were independent preoperative risk factors for early mortality, while cardiac tamponade (n = 34, 2.3%) (OR 10.282, 95% CI 4.640-22.785, P < 0.001), cerebral ischaemia (n = 80, 5.3%) (OR 2.409, 95% CI 1.179-4.923, P = 0.016) and mesenteric ischaemia (n = 15, 1.0%) (OR 44.763, 95% CI 13.027-153.808, P < 0.001) were independent postoperative risk factors. CONCLUSIONS: Not only critical preoperative conditions but also postoperative cardiac tamponade and vital organ ischaemia are risk factors for early mortality after acute type A aortic dissection repair.

BACKGROUND: In the modern US cardiovascular intensive care unit (CICU), the incidence of non-cardiovascular disorders has increased and non-cardiovascular disorders are associated with an increase in morbidity and mortality. In Japan, however, data regarding the association between non-cardiovascular disorders and outcomes in the CICU are limited. METHODS: This study examined 490 consecutive admissions to a closed CICU at the Nippon Medical School Hospital from January to December 2017. Characteristics, diagnoses, treatments, and outcomes of admitted patients were identified. RESULTS: The most common primary diagnosis was acute coronary syndrome (50.4%), followed by acute heart failure (20.0%), arrhythmia (6.7%), and non-cardiovascular diseases (3.7%). The mortality rate and median length of stay (LOS) in the CICU were 4.7% and 4 (interquartile range, 2-8) days, respectively. Of all patients, 42.2% (n = 207) developed non-cardiovascular complications such as acute respiratory failure, acute kidney injury, or sepsis during CICU stay. Multivariate logistic regression analysis revealed that acute respiratory failure and sepsis were significantly associated with mortality in the CICU (odds ratio, 11.014 and 25.678, respectively; both p<0.05). The multiple linear regression analysis showed that acute kidney injury was significantly associated with LOS in the CICU (ß=0.144, p = 0.002). CONCLUSIONS: Approximately half of patients admitted to the CICU had non-cardiovascular disorders including non-cardiovascular disease and non-cardiovascular complications, which were significantly associated with mortality and LOS in the CICU.

BACKGROUND: An inter-arm difference in blood pressure (IADBP) is characteristic of acute aortic dissection (AAD), but the importance of which arm exhibits lower blood pressure (BP) and the mechanism underlying IADBP are not well understood. METHODS: We identified consecutive patients with chest and/or back pain and suspected acute cardiovascular disease whose BP had been measured in both arms. We retrospectively compared the characteristics of such patients with AAD (n=93) to those without AAD (non-AAD group, n=122). Additionally, we separately compared patients with type A AAD (TAAD group, n=58) or type B AAD (TBAD group, n=35) to the non-AAD group. The characteristics analyzed were patient background and IADBP-related factors, including systolic BP (SBP) in the right arm (R) and left arm (L), and R-L or L-R as IADBP. Computed tomography (CT) findings of AD extending to the brachiocephalic artery (BCA) and/or left subclavian artery (LSCA) were examined in patients with an IADBP. RESULTS: In a comparison of the TAAD group and non-AAD group, the prevalences of R <130 mm Hg (38% vs. 19%, p=0.009), L-R >15 mm Hg (19% vs. 8%, p=0.047), L-R >20 mm Hg (14% vs. 4%, p=0.029) were higher in the TAAD group. Multivariate analysis showed that L-R >15 mm Hg with R <130 mm Hg was independently associated with TAAD (OR 25.97, 95% CI 2.45-275.67, p=0.007). However, IADBP-related factors were not associated with TBAD. AAD patients with L-R >20 mm Hg all had TAAD, and all aortic dissection extended to the BCA just before the right common carotid artery on CT. CONCLUSIONS: IADBP was characterized by RAssuntos
