RESUMO

BACKGROUND: Given the global shortage of child psychiatrists and barriers to specialized care, remote assessment is a promising alternative for diagnosing and managing attention-deficit/hyperactivity disorder (ADHD). However, only a few studies have validated the accuracy and acceptability of these remote methods. OBJECTIVE: This study aimed to test the agreement between remote and face-to-face assessments. METHODS: Patients aged between 6 and 17 years with confirmed Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition diagnoses of ADHD or autism spectrum disorder (ASD) were recruited from multiple institutions. In a randomized order, participants underwent 2 evaluations, face-to-face and remotely, with distinct evaluators administering the ADHD Rating Scale-IV (ADHD-RS-IV). Intraclass correlation coefficient (ICC) was used to assess the reliability of face-to-face and remote assessments. RESULTS: The participants included 74 Japanese children aged between 6 and 16 years who were primarily diagnosed with ADHD (43/74, 58%) or ASD (31/74, 42%). A total of 22 (30%) children were diagnosed with both conditions. The ADHD-RS-IV ICCs between face-to-face and remote assessments showed "substantial" agreement in the total ADHD-RS-IV score (ICC=0.769, 95% CI 0.654-0.849; P<.001) according to the Landis and Koch criteria. The ICC in patients with ADHD showed "almost perfect" agreement (ICC=0.816, 95% CI 0.683-0.897; P<.001), whereas in patients with ASD, it showed "substantial" agreement (ICC=0.674, 95% CI 0.420-0.831; P<.001), indicating the high reliability of both methods across both conditions. CONCLUSIONS: Our study validated the feasibility and reliability of remote ADHD testing, which has potential benefits such as reduced hospital visits and time-saving effects. Our results highlight the potential of telemedicine in resource-limited areas, clinical trials, and treatment evaluations, necessitating further studies to explore its broader application.

RESUMO

Long-term outcomes of iatrogenic coronary dissection and perforation in patients undergoing percutaneous coronary intervention (PCI) remains under-investigated. We analyzed 8,721 consecutive patients discharged after PCI between 2008 and 2019 from Keio Cardiovascular (KiCS) PCI multicenter prospective registry in the Tokyo metropolitan area. Significant coronary dissection was defined as persistent contrast medium extravasation or spiral or persistent filling defects with complete distal and impaired flow. The primary outcome was a composite of all-cause death, acute coronary syndrome, heart failure, bleeding, stroke requiring admission, and coronary artery bypass grafting two years after discharge. We used a multivariable Cox hazard regression model to assess the effects of these complications. Among the patients, 68 (0.78%) had significant coronary dissections, and 61 (0.70%) had coronary perforations at the index PCI. Patients with significant coronary dissection had higher rates of the primary endpoint and heart failure than those without (25.0% versus 14.3%, P = 0.02; 10.3% versus 4.2%, P = 0.03); there were no significant differences in the primary outcomes between the patients with and without coronary perforation (i.e., primary outcome: 8.2% versus 14.5%, P = 0.23) at the two-year follow-up. After adjustments, patients with coronary dissection had a significantly higher rate of the primary endpoint than those without (HR 1.70, 95% CI 1.02-2.84; P = 0.04), but there was no significant difference in the primary endpoint between the patients with and without coronary perforation (HR 0.51, 95% CI 0.21-1.23; P = 0.13). For patients undergoing PCI, significant coronary dissection was associated with poor long-term outcomes, including heart failure readmission.

RESUMO

Young patients who underwent percutaneous coronary intervention (PCI) have shown worse long-term outcomes but remain inadequately investigated. We analyzed 1,186 consecutive young patients (aged ≤55 years) from the Keio Cardiovascular PCI registry who were successfully discharged after PCI (2008 to 2019) and compared them to 5,048 older patients (aged 55 to 75 years). The primary outcome was a composite of all-cause death, acute coronary syndrome, heart failure, bleeding, stroke requiring admission, and coronary artery bypass grafting within 2 years after discharge. In the young patients, the mean age was 48.4 ± 5.4 years, acute coronary syndrome cases accounted for 69.6%, and 92 (7.8%) were female. Body mass index; hemoglobin levels; and proportions of smoking, hyperlipidemia, and ST-elevation myocardial infarction were lower and dialysis or active cancer proportions were higher in young female patients than male patients. A higher number of young female than male patients reached the primary end point and all-cause death (15.2% vs 7.1%, p = 0.01; 4.3% vs 1.0%, p = 0.023), mainly because of noncardiac death (4.3% versus 0.5%, p = 0.001). After covariate adjustment, the primary end point rates were higher among young women than men (hazard ratio 2.00, 95% confidence interval 1.03 to 3.89, p = 0.042). Gender did not predict the primary end point among older patients (vs men; hazard ratio 0.84, 95% confidence interval 0.67 to 1.06, p = 0.14). In conclusion, young women showed worse outcomes during the 2-year post-PCI follow-up, but this gender difference was absent in patients aged 55 to 75 years.

RESUMO

Background: Traditional methods of risk assessment for thoracic aortic aneurysm (TAA) based on aneurysm size alone have been called into question as being unreliable in predicting complications. Biomechanical function of aortic tissue may be a better predictor of risk, but it is difficult to determine in vivo. Objectives: This study investigates using a machine learning (ML) model as a correlative measure of energy loss, a measure of TAA biomechanical function. Methods: Biaxial tensile testing was performed on resected TAA tissue collected from patients undergoing surgery. The energy loss of the tissue was calculated and used as the representative output. Input parameters were collected from clinical assessments including observations from medical scans and genetic paneling. Four ML algorithms including Gaussian process regression were trained in Matlab. Results: A total of 158 patients were considered (mean age 62 years, range 22-89 years, 78% male), including 11 healthy controls. The mean ascending aortic diameter was 47 ± 10 mm, with 46% having a bicuspid aortic valve. The best-performing model was found to give a greater correlative measure to energy loss (R2 = 0.63) than the surprisingly poor performance of aortic diameter (R2 = 0.26) and indexed aortic size (R2 = 0.32). An echocardiogram-derived stiffness metric was investigated on a smaller subcohort of 67 patients as an additional input, improving the correlative performance from R2 = 0.46 to R2 = 0.62. Conclusions: A preliminary set of models demonstrated the ability of a ML algorithm to improve prediction of the mechanical function of TAA tissue. This model can use clinical data to provide additional information for risk stratification.

RESUMO

BACKGROUND: Sex differences in the outcomes following percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) have been identified in Western countries. However, data on the long-term outcomes for bleeding events, particularly in East Asia where the aging population is growing rapidly and consists predominantly of women, remain scarce. METHODS: We analyzed 2,494 ACS survivors from a multicenter PCI registry who underwent PCI between 2009 and 2012. The primary outcome was readmission for major bleeding at 2 years. Survival curves were generated with the cumulative incidence function. The adjusted hazard ratios were evaluated for the primary outcomes by sex using (1) Fine-Gray models and (2) Cox regression models. RESULTS: There were 548 women (22.0%) in this cohort. The women were older (73.7 ± 10.8 years vs. 65.4 ± 11.8 years, p < 0.001), had a lower body mass index (23.0 ± 3.9 vs. 24.3 ± 3.6, p < 0.001), and had more comorbidities such as renal failure (49.4% vs. 36.3%, p < 0.001) and previous heart failure (8.4% vs. 4.5%, p < 0.001). Fewer women were discharged with statins (81.9% vs. 86.5%, p = 0.025) or beta blockers (70.6% vs. 77.1%, p = 0.007). During the 2-year follow-up, the unadjusted readmission rates for bleeding were higher among women (4.9% versus 2.4% at 2 years after discharge). Multivariable competing risk analysis with the Fine-Gray model and Cox regression model further demonstrated that female sex was associated with a higher risk of bleeding. CONCLUSIONS: Among patients treated with PCI, women had a higher incidence of bleeding events requiring readmission. Sex disparities in the etiologies of readmission following PCI suggest the need for targeted treatment strategies. A strict follow-up after discharge could be beneficial for women to further reduce their risk.

RESUMO

The Academic Research Consortium (ARC) recently published a definition of patients at high bleeding risk (HBR) undergoing percutaneous coronary intervention. However, the prevalence of the ARC-HBR criteria in patients undergoing endovascular therapy (EVT) for peripheral artery disease in lower extremities has not been thoroughly investigated. This study sought to investigate the prevalence and impact of the ARC-HBR criteria in patients undergoing EVT. We analyzed 277 consecutive patients who underwent their first EVT from July 2011 to September 2019. We applied the full ARC-HBR criteria to the study population. The primary end point was a composite outcome of all-cause mortality, Bleeding Academic Research Consortium 3 or 5 bleeding, and lower limb amputation within 12 months of EVT. Among the 277 patients, 193 (69.7%) met the ARC-HBR criteria. HBR patients had worse clinical outcomes compared with non-HBR patients at 12 months after EVT, including a higher incidence of the composite primary outcome (19.2% vs. 3.6%, p < 0.001) and all-cause death (7.8% vs. 0%, p = 0.007). In a multivariate Cox proportional hazards regression analysis, presence of the ARC-HBR criteria [hazard ratio (HR) 4.15, 95% confidence interval (CI) 1.25-13.80, p = 0.020], body mass index (HR 1.13, 95% CI 1.01-1.27, p = 0.042), diabetes mellitus (HR 2.70, 95% CI 1.28-5.69, p = 0.009), hyperlipidemia (HR 0.41, 95% CI 0.21-0.80, p = 0.009), and infrapopliteal lesions (HR 3.51, 95% CI 1.63-7.56, p = 0.001) were independent predictors of the primary composite outcome. Approximately 70% of Japanese patients undergoing EVT met the ARC-HBR criteria, and its presence was strongly associated with adverse outcomes within 12 months of EVT.

RESUMO

Acute kidney injury (AKI) is common in patients undergoing percutaneous coronary intervention (PCI). One risk factor for AKI is periprocedural hemoglobin drop level (> 3 g/dL); however, whether the relationship between hemoglobin drop and AKI is linear or nonlinear remains unknown. We aimed to investigate the relationship between periprocedural hemoglobin drop and AKI after PCI. We evaluated 14,273 consecutive patients undergoing PCI between September 2008 and March 2019. AKI was defined as an absolute or a relative increase in serum creatinine level of 0.3 mg/dL or 50%, respectively. Restricted cubic spline was constructed to assess the association between hemoglobin drop and AKI by logistic regression and machine learning (ML) models, which were used to predict the risk of AKI. The patients' mean age was 68.4 ± 11.6 years; the AKI incidence was 10.5% (N = 1499). An absolute > 3 g/dL or 20% relative decrease in hemoglobin level was an independent predictor of AKI incidence (odds ratio, OR [95% confidence interval, CI]: 2.24 [1.92-2.61], P < 0.001; 2.35 [2.04-2.71], P < 0.001, respectively). An adjusted restricted cubic spline demonstrated that absolute/relative decrease in hemoglobin was linearly associated with AKI. Logistic and ML models with absolute/relative hemoglobin changes were comparable while estimating the risk of AKI (absolute area under the curve [AUC] (logistic):0.826, AUC (ML): 0.820; relative AUC (logistic): 0.818, AUC (ML): 0.816). An absolute/relative decrease in periprocedural hemoglobin after PCI was linearly associated with AKI. Detection of a relative/absolute decrease in hemoglobin may help clinicians identify individuals as high risk for AKI after PCI.

RESUMO

BACKGROUND: Mechanical circulatory support (MCS) with Impella or intra-aortic balloon pump (IABP) is used for high-risk percutaneous coronary intervention (PCI) and/or for cardiogenic shock (CS) due to acute myocardial infarction. We aimed to investigate the efficacy and safety of Impella or IABP when compared with no MCS using a network meta-analysis of randomized controlled trials (RCTs). METHODS: EMBASE and MEDLINE were searched through February 2020 for RCT evaluating efficacy of Impella vs. IABP vs. no MCS in patients undergoing high-risk PCI or CS. The primary efficacy outcome was 30 day or in-hospital all-cause mortality whereas the primary safety outcomes were major bleeding and vascular complications. RESULTS: Our search identified nine RCTs enrolling a total of 1,996 patients with high-risk PCI and/or CS. There was no significant difference with Impella or IABP on all-cause mortality when compared with no MCS (Impella vs. no MCS; OR:0.82 [0.35-1.90], p = .65, IABP vs. no MCS; OR:0.77 [0.47-1.28], p = .31, I2 = 18.1%). Impella significantly increased major bleeding compared with no MCS (Impella vs. no MCS; OR:7.01 [1.11-44.4], p = .038, I2 = 19.2%). IABP did not increase the risk of major bleeding compared with no MCS (OR:1.27 [0.75-2.16], p = .38, I2 = 19.2%) but increased vascular complication compared with no MCS (OR:1.92 [1.01-3.64], p = .045, I2 = 1.5%). CONCLUSIONS: Neither Impella nor IABP decreased all-cause short-term mortality when compared with no MCS for high-risk PCI and/or CS. Moreover, Impella increased major bleeding compared with no MCS.

RESUMO

Although baseline hemoglobin and renal function are both important predictors of adverse outcomes after percutaneous coronary intervention (PCI), scarce data exist regarding the combined impact of these factors on outcomes. We sought to investigate the impact and threshold value of the hemoglobin to creatinine (Hgb/Cr) ratio, on in-hospital adverse outcomes among non-dialysis patients in a Japanese nationwide registry. We analyzed 157,978 non-dialysis patients who underwent PCI in 884 Japanese medical institutions in 2017. We studied differences in baseline characteristics and in-hospital clinical outcomes among four groups according to their quartiles of the Hgb/Cr ratios. Compared with patients with higher Hgb/Cr ratios, patients with lower ratios were older and had more comorbidities and complex coronary artery disease. Patients with lower hemoglobin and higher creatinine levels had a higher rate of in-hospital adverse outcomes including in-hospital mortality and procedural complications (defined as occurrence of cardiac tamponade, cardiogenic shock after PCI, emergency operation, or bleeding complications that required blood transfusion). On multivariate analyses, Hgb/Cr ratio was inversely associated with in-hospital mortality (odds ratio: 0.91, 95% confidence interval: 0.89-0.92; p < 0.001) and bleeding complications (odds ratio: 0.92, 95% confidence interval: 0.90-0.94; p < 0.001). Spline curve analysis demonstrated that these risks started to increase when the Hgb/Cr ratio was <15, and elevated exponentially when the ratio was <10. Hgb/Cr ratio is a simple index among non-dialysis patients and is inversely associated with in-hospital mortality and bleeding complications after PCI.

RESUMO

We herein describe a 49-year-old woman without significant cardiovascular risk factors who was transferred to our hospital with sudden onset of chest pain. The patient was diagnosed with non-ST-elevation acute myocardial infarction, and coronary angiography revealed a dissection at the proximal site of the left anterior descending artery (LAD) extending from the left main trunk (LMT) suggestive of spontaneous coronary artery dissection (SCAD). Because coronary flow was impaired after contrast injection and the patient had chest pain with ST elevation, urgent percutaneous coronary intervention was performed. The first guide wire was initially introduced from the LMT to the distal LAD, but intravascular ultrasound (IVUS) imaging revealed that the guide wire had passed through the true lumen of the left coronary artery ostium, false lumen at the ostium of the left circumflex artery, and true lumen of the distal LAD. We then reinserted another guide wire using an IVUS-guided rewiring technique from the true lumen of the LMT to the distal LAD. Finally, a drug-eluting stent was deployed to cover the dissected segment, and final coronary angiography revealed acceptable results with a patent left circumflex artery. This case report highlights that physicians should consider SCAD among the differential diagnoses in patients presenting with acute coronary syndrome, particularly in young women. In the present case, IVUS played a pivotal role in not only detecting the arterial dissection but also correctly introducing the guide wire into the true lumen.

RESUMO

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become the main treatment for symptomatic severe aortic stenosis, but patients on dialysis have been excluded from major randomized controlled trials. Our aim was to compare mortality and procedure-related complications after TAVI in patients with end-stage renal disease (ESRD) on dialysis vs those without. METHODS: EMBASE and MEDLINE were searched through November 2019 to investigate the comparative outcomes between patients with ESRD on dialysis and those without who underwent TAVI. The main outcomes were short-term (30-day/in-hospital) mortality and procedural complications, and long-term (>6 months) all-cause mortality. RESULTS: Our search identified 10 observational studies enrolling 128,094 (5399 on dialysis) patients who underwent TAVI. Dialysis patients had a significantly higher rate of short-term and long-term mortality than nondialysis patients (odds ratio [95% confidential interval]: 2.18 [1.64-2.89], P < 0.001, I2 = 60%; 1.91 [1.46-2.50], P < 0.001, I2 = 80%, respectively). In addition, dialysis patients had significantly higher rates of short-term life-threatening and/or major bleeding, permanent pacemaker implantation, and device failure compared with nondialysis patients (odds ratio [95% confidential interval]: 1.90 [1.24-2.90], P < 0.001, I2 = 67%; 1.33 [1.15-1.53], P < 0.001, I2 = 0%; 2.08 [1.05-4.10], P = 0.03, respectively), but did not have significantly higher rates of vascular complications and stroke. CONCLUSION: Dialysis patients had significantly higher rates of short- and long-term mortality, short-term life-threatening and/or major bleeding, permanent pacemaker implantation, and device failure compared with nondialysis patients. Careful selection of patients who would benefit from TAVI among patients with ESRD requiring dialysis is necessary to prevent high rates of postprocedural complications.

RESUMO

Amputation has been known to be a rare adverse event of sodium glucose co-transporter-2 (SGLT2) inhibitors. It remains unclear whether the SGLT2 inhibitor as a class or specific categories of the SGLT2 inhibitors are linked with an increased risk of amputation. The objective of this meta-analysis was to investigate the association between the amputation risk and the use of SGLT2 inhibitors. The main outcome measure was the risk of amputation. Multiple databases were searched up to February 2020 and data extraction was performed. Inclusion criteria were randomized controlled trials (RCTs) which reported risk of amputation with SGLT2 inhibitors over non-SGLT2 inhibitors or placebo. The risk of bias was assessed by Cochrane bias tool. The initial search yielded 1,873 citations and a total of five RCTs were included in the meta-analysis. The five included studies evaluated a total of 39,067 patients with diabetes mellitus, including 21,395 patients on SGLT2 inhibitors. The incidence rate of amputation ranged from 0.36 to 3.18% in the SGLT2 inhibitor group and from 0% to 2.87% in the control group. Follow up duration ranged from 24 weeks to 4.2 years. Use of SGLT2 inhibitors was not associated with significant increase in the risk of amputation as compared with controls (OR: 1.31, 95% CI: 0.92-1.87, I2 = 75%). Subgroup analysis showed that neither canagliflozin, empagliflozin, nor dapagliflozin was associated with increased risk of amputation. In conclusion, our meta-analysis showed that neither canagliflozin nor other SGLT2 inhibitors increase the risk of amputation.

RESUMO

Four-dimensional computed tomography has been used to evaluate moving structures and is a useful method to diagnose cardiovascular diseases. We report a case of cerebral infarction due to the thrombus in the ascending aorta, and utilized 4-dimensional computed tomography angiography for visualizing the movement of the thrombus, which prompted early surgical intervention to prevent further thromboembolism. Although transesophageal echocardiography is an established method to evaluate the ascending aorta, it has some contraindications and complications. Four-dimensional computed tomography angiography is an excellent alternative without blind spots to evaluate the ascending aorta more quickly than transesophageal echocardiography.

RESUMO

BACKGROUND: Patients on long-term dialysis are at increased risk of bleeding. Although oral anticoagulants (OACs) are recommended for atrial fibrillation (AF) to reduce the risk of stroke, randomized trials have excluded these populations. As such, the net clinical benefit of OACs among patients on dialysis is unknown. OBJECTIVES: This study aimed to investigate the efficacy and safety of OACs in patients with AF on long-term dialysis. METHODS: MEDLINE and EMBASE were searched through June 10, 2019, for studies that investigated the efficacy and safety of different OAC strategies in patients with AF on long-term dialysis. The efficacy outcomes were ischemic stroke and/or systemic thromboembolism, all-cause mortality, and the safety outcome was major bleeding. RESULTS: This study identified 16 eligible observational studies (N = 71,877) regarding patients on long-term dialysis who had AF. Only 2 of 16 studies investigated direct OACs. Outcomes for dabigatran and rivaroxaban were limited to major bleeding events. Compared with no anticoagulants, apixaban and warfarin were not associated with a significant decrease in stroke and/or systemic thromboembolism (apixaban 5 mg, hazard ratio [HR]: 0.59; 95% confidence interval [CI]: 0.30 to 1.17; apixaban 2.5 mg, HR: 1.00; 95% CI: 0.52 to 1.93; warfarin, HR: 0.91; 95% CI: 0.72 to 1.16). Apixaban 5 mg was associated with a significantly lower risk of mortality (vs. warfarin, HR: 0.65; 95% CI: 0.45 to 0.93; vs. apixaban 2.5 mg, HR: 0.62; 95% CI: 0.42 to 0.90; vs. no anticoagulant, HR: 0.61; 95% CI: 0.41 to 0.90). Warfarin was associated with a significantly higher risk of major bleeding than apixaban 5 min/2.5 mg and no anticoagulant (vs. apixaban 5 mg, HR: 1.41; 95% CI: 1.07 to 1.88; vs. apixaban 2.5 mg, HR: 1.40; 95% CI: 1.07 to 1.82; vs. no anticoagulant, HR: 1.31; 95% CI: 1.15 to 1.50). Dabigatran and rivaroxaban were also associated with significantly higher risk of major bleeding than apixaban and no anticoagulant. CONCLUSIONS: This meta-analysis showed that OACs were not associated with a reduced risk of thromboembolism in patients with AF on long-term dialysis. Warfarin, dabigatran, and rivaroxaban were associated with significantly higher bleeding risk compared with apixaban and no anticoagulant. The benefit-to-risk ratio of OACs in patients with AF on long-term dialysis warrants validation in randomized clinical trials.

RESUMO

Peripheral artery disease (PAD) is associated with high cardiovascular mortality. Which part of PAD with lower extremities is related to coronary artery disease (CAD) remains unknown. We hypothesized that PAD including infrapopliteal artery (IPA) occlusion was associated with CAD. A total of 260 patients who have no history of CAD or the anginal symptom, complain of the claudication or critical limb ischemia and underwent peripheral angiography were retrospectively analyzed. IPA occlusion was diagnosed with peripheral angiography, and CAD was diagnosed with the coronary angiography. A multivariate logistic regression analysis was performed to determine the predictors of silent CAD. Among them, a total of 146 patients (56.2%) had IPA occlusion. Baseline characteristics were significantly different between two groups as to the proportions of age, male, dyslipidemia (with vs. without IPA occlusion; 72.4 ± 10.8 vs. 69.1 ± 10.2; 62.3% vs. 75.4%; 38.6% vs. 52.6%, respectively, all comparisons P < 0.05). Notably, the prevalence of CAD was significantly higher in patients with IPA occlusion (50.7% vs. 34.2%, P = 0.008). On a multivariate analysis, IPA occlusion was an independent predictor for the presence of silent CAD (OR, 1.94; CI, 1.09-3.44, P = 0.024), but aortoiliac artery occlusion (OR, 1.16; CI, 0.53-2.56, P = 0.71) and femoropopliteal artery occlusion (OR, 1.02; CI, 0.57-1.83, P = 0.96) were not. IPA occlusion was associated with silent CAD. Vascular surgeons, interventional radiologists, as well as interventional cardiologists should recognize IPA occlusion as a risk factor of silent CAD.

RESUMO

OBJECTIVES: We aimed to investigate the efficacy and safety of different antithrombotic strategies in patients undergoing transcatheter aortic valve implantation (TAVI) using network meta-analyses. BACKGROUND: Meta-analyses comparing single antiplatelet therapy (SAPT) vs. dual antiplatelet therapy (DAPT), ± oral anticoagulant (OAC) was conducted to determine the appropriate post TAVI antithrombotic regimen. However, there was limited direct comparisons across the different therapeutic strategies. METHODS: MEDLINE and EMBASE were searched through December 2018 to investigate the efficacy and safety of different antithrombotic strategies (SAPT, DAPT, OAC, OAC + SAPT, and OAC + DAPT) in patients undergoing TAVI. The main outcome were all-cause mortality, major or life-threatening bleeding events, and stroke. RESULTS: Our search identified 3 randomized controlled trials and 10 nonrandomized studies, a total of 20,548 patients who underwent TAVI. All OACs were vitamin K antagonists. There was no significant difference on mortality except that OAC + DAPT had significantly higher rates of mortality compared with others (p < .05, I2 = 0%). SAPT had significantly lower rates of bleeding compared with DAPT, OAC+SAPT, and OAC+DAPT (hazard ratio [HR]: 0.59 [0.46-0.77], p < .001, HR: 0.58 [0.34-0.99], p = .045, HR: 0.41 [0.18-0.93], p = .033, respectively, I2 = 0%). There was no significant difference on stroke among all antithrombotic strategies. CONCLUSION: Patients who underwent TAVI had similar all-cause mortality rates among different antithrombotic strategies except OAC+DAPT. Patients on SAPT had significantly lower bleeding risk than those on DAPT, OAC + SAPT, and OAC + DAPT. Our results suggest SAPT is the preferred regimen when there is no indication for DAPT or OAC. When DAPT or OAC is indicated, DAPT + OAC should be avoided.

RESUMO

BACKGROUND: Extra-cardiac vascular diseases (ECVDs), such as cerebrovascular disease (CVD) or peripheral arterial disease (PAD), are frequently observed among patients with acute coronary syndrome (ACS). However, it is not clear how these conditions affect patient outcomes in the era of transradial coronary intervention (TRI). METHODS AND RESULTS: Among 7,980 patients with ACS whose data were extracted from the multicenter Japanese percutaneous coronary intervention (PCI) registry between August 2008 and March 2017, 888 (11.1%) had one concurrent ECVD (either PAD [345 patients: 4.3%] or CVD [543 patients; 6.8%]), while 87 patients (1.1%) had both PAD and CVD. Overall, the presence of ECVD was associated with a higher risk of mortality (odds ratio [OR]: 1.728; 95% confidence interval [CI]: 1.183-2.524) and bleeding complications (OR: 1.430; 95% CI: 1.028-2.004). There was evidence of interaction between ECVD severity and procedural access site on bleeding complication on the additive scale (relative excess risk due to interaction: 0.669, 95% CI: -0.563-1.900) and on the multiplicative scale (OR: 2.105; 95% CI: 1.075-4.122). While the incidence of death among patients with ECVD remained constant during the study period, bleeding complications among patients with ECVD rapidly decreased from 2015 to 2017, in association with the increasing number of TRI. CONCLUSIONS: Overall, the presence of ECVD was a risk factor for adverse outcomes after PCI for ACS, both mortality and bleeding complications. In the most recent years, the incidence of bleeding complications among patients with ECVD decreased significantly coinciding with the rapid increase of TRI.

RESUMO

BACKGROUND: The Great East Japan Earthquake (GEJE) and tsunami of March 11, 2011 left behind many survivors, including children. This study aimed to assess changes in traumatic symptoms with time among kindergarteners who experienced GEJE as infants and to discuss the relationship between these symptoms and the disaster experience. METHODS: The 15-item Post-Traumatic Stress Symptoms for Children (PTSSC-15) questionnaire were distributed to the parents of kindergarteners (children aged 4-5 years) at 8, 20, 30, and 42 months after GEJE. Questionnaires regarding environmental damage conditions affecting the children were distributed to teachers 8 months after the tsunami. RESULTS: The number of kindergarteners was 262, 255, 236, and 202 at 8, 20, 30, and 42 months after the disaster. The PTSSC-15 total score was not different between kindergartners with and without environmental damage conditions. After 8 and 20 months, the PTSSC-15 total score of children who usually ate breakfast was significantly higher than that of children who did not. Moreover, after 30 and 42 months, the PTSSC-15 total score of kindergarteners who usually ate breakfast was not significantly higher than that of kindergarteners who did not. CONCLUSIONS: The traumatic symptoms of kindergarteners were not related to disaster experiences.
