RESUMO
PURPOSE: Chemotherapy-induced cardiotoxicity is a critical issue for patients with breast cancer. Change of epicardial adipose tissue (EAT) is associated with cardiac dysfunction. The objective of this study was to investigate the relationship between EAT and chemotherapy-induced cardiotoxicity. METHODS: This retrospective study analyzed EAT on chest computed tomography (CT) of patients with early breast cancer using automatic, quantitative measurement software between November 2015 and January 2020. Changes in EAT before and after initiation of chemotherapy were compared according to the type of anticancer drug. Subclinical cardiotoxicity was defined as worsening ≥ 10% in left ventricular ejection fraction to an absolute value > 50% with a lower limit of normal measured with standard echocardiography. RESULTS: Among 234 patients with breast cancer, 85 were treated with adjuvant anthracycline-based (AC) and 149 were treated with non-anthracycline-based (non-AC) chemotherapy. There was a significant increase in EAT volume index (mL/kg/m2) at the end of chemotherapy compared to that at the baseline in the AC group (3.33 ± 1.53 vs. 2.90 ± 1.52, p < 0.001), but not in the non-AC group. During the follow-up period, subclinical cardiotoxicity developed in 20/234 (8.6%) patients in the total population [13/85 (15.3%) in the AC group and 7/149 (4.8%) in the non-AC group]. In the multivariable analysis, EAT volume index increment after chemotherapy was associated with a lower risk of subclinical cardiotoxicity in the AC group (Odds ratio: 0.364, 95% CI 0.136-0.971, p = 0.044). CONCLUSIONS: Measurement of EAT during anthracycline-based chemotherapy might help identify subgroups who are vulnerable to chemotherapy-induced cardiotoxicity. Early detection of EAT volume change could enable tailored chemotherapy with cardiotoxicity prevention strategies.

Background and Objectives: Appropriate catheter selection when conducting transradial coronary angiography (CAG) helps shorten examination time, preventing vascular complications and lowering medical expense. However, catheter selection is made based on the practitioner's experience in almost all cases. Therefore, we undertook this study to define radiologic and echocardiographic indices that would enable physicians to anticipate appropriate catheter selection. Materials and Methods: This is a retrospective study of 244 undergoing transradial diagnostic CAG at an established center from February 2006 to April 2014. Patients who successfully underwent angiography with a JL3.5 catheter were defined as the control group, and patients who successfully underwent angiography after the catheter was replaced with a JL4.0 or higher were defined as the switched group. To identify predictors for appropriate catheter selection, radiologic and echocardiographic indices were analyzed. Results: A total of 122 patients in the switched group and 122 patients in the control group were analyzed in this study. Average age was 64.65 ± 8.6 years. In the radiographic index, the switched group exhibited a significantly higher mediastinal-thoracic ratio (0.27 ± 0.05 vs. 0.23 ± 0.03, p < 0.001. Additionally, the mediastinal-cardiac ratio was significantly greater in the switched group (0.50 ± 0.08 vs. 0.45 ± 0.05, p < 0.001). Aortic root diameter, which is used here as the echocardiographic index, was significantly larger in the switched group compared to the control group (34.94 ± 4.18 mm vs. 32.66 ± 3.99 mm, p < 0.001). In the multivariable logistic regression model, mediastinal-cardiac ratio (OR 5.197, 95% CI 2.608-10.355, p < 0.001) and increased aortic root (OR 2.115, 95% CI 1.144-3.912, p = 0.017) were significantly associated with catheter change. Conclusions: Mediastinal-cardiac ratio and aortic root diameter provide helpful and effective indices for appropriate catheter selection during transradial coronary angiography.

BACKGROUND: Percutaneous cannulation of femoral vessels has been widely used for the rapid deployment of extracorporeal life support (ECLS). Limb ischaemia is a devastating complication in patients receiving ECLS. Our aim was to evaluate the predictors of limb ischaemia during ECLS and to determine the role of preventative distal perfusion. METHODS: Two hundred and fifty-five consecutive patients who received veno-arterial ECLS due to cardiac and/or respiratory failure were enrolled from January 2009 to December 2015. All patients received ECLS for more than 6 hours and the data was reviewed retrospectively. Distal perfusion to minimise lower limb ischaemia was performed at the discretion of the physician. Predictors for lower limb ischaemia during ECLS were analysed using multivariate regression analysis. RESULTS: For the 255 patients, the mean age was 58 and 177 (69.4%) were male. Limb ischaemia developed in 24 patients (9.4%); 178 patients (69.8%) died within 30 days. Among the 24 patients, one patient (4.2%) developed limb ischaemia with preventative distal perfusion. Fourteen patients (58.3%) received therapeutic distal perfusion. After distal perfusion, two patients (8.3%) still required surgical intervention. Limb ischaemia was more frequent in female patients (54.2% in the ischaemia group versus 28.1% in the non-ischaemia group, p=0.008) and shorter patients (162.0 ± 9.5 cm in the ischaemia group versus 166.3 ± 9.1 cm in the non-ischaemia group, p=0.027). Patients shorter than 165 cm were more commonly diagnosed with ischaemia compared to those who were taller than 165 cm (79.2% versus 40.7%, p<0.001). In a multivariate regression analysis, height under 165 cm was the only predictor for limb ischaemia (Odds ratio (OR) [95% confidence interval (CI)] = 12.645 [3.190-50.118]). CONCLUSION: Smaller female patients are more prone to developing limb ischaemia from femoral ECLS. Our findings might support preventative distal perfusion and more careful observation of these patients.

BACKGROUND: We recently reported an increased risk of herpes zoster (shingles or zoster) in children with asthma, but little is known about whether the same is true for adults with asthma. OBJECTIVE: We determined whether asthma is associated with an increased risk of zoster in adults. METHODS: This study was designed as a population-based case-control study. Zoster cases during the study period were identified among adults (aged ≥50 years) who resided in Olmsted County, Minnesota. We compared the frequency of asthma between zoster cases and birthday- and sex-matched control subjects (1:2 matching) without a history of zoster. Asthma status was ascertained based on predetermined criteria. A conditional logistic regression model was used to assess the association of asthma with risk of zoster. RESULTS: A total of 371 zoster cases and their 742 matched control subjects were enrolled. Of the 371 cases, 246 (66%) were female, 348 (94%) were white, and the mean ± SD age was 66.8 ± 10.7 years. Twenty-three percent (n = 87) of zoster cases had a history of asthma compared with 15% (n = 114) of control subjects. Controlling for pertinent covariates and confounders, there was a significant association between a history of asthma and risk of zoster (adjusted odds ratio, 1.70; 95% CI, 1.20-2.42; P = .003). The population attributable risk percentage for asthma was about 10%. CONCLUSIONS: Asthma is an unrecognized risk factor for zoster in adults. Consideration should be given to immunizing adults with asthma aged more than 50 years as a target group.

Objective: Serum hemoglobin (Hb) level affects the viscosity of blood. Several studies have reported that Hb level is associated with adverse cardiovascular outcome. However, there is a paucity of evidence on the association between serum Hb level and the risk of subclinical atherosclerosis. Thus, the objective of this study was to investigate the relationship between Hb level and risk of carotid plaque in a health checkup cohort. Methods: This retrospective study analyzed a total of 3,805 individuals without history of cardiovascular disease (CVD) who underwent carotid ultrasonography (USG) between January 2016 and June 2018. Participants were divided into 4 groups based on Hb quartiles in each of male and female. Carotid plaque score was calculated based on USG reports. Multivariable logistic regression analysis was performed for each index of quartile groups regarding the risk of carotid plaque. Results: Of 3,805 individuals (mean age, 52.62±10.25 years; 2,674 [70.28%] males), mean Hb level was 15.11±0.75 g/dL in male and 13.35±0.74 g/dL in female. When the Q1 group was compared to the Q4, increasing quartile of Hb was associated with the presence of significant carotid plaque (plaque score ≥3) in male (adjusted odds ratio [OR], 1.538; 95% confidence interval [CI], 1.182-2.001; p=0.001) and female (adjusted OR, 1.749; 95% CI, 1.058-2.676; p=0.01). Conclusion: A high Hb level is associated with an increased risk of carotid plaques in individuals without history of CVD. This finding may support the need for early screening of CVD in individuals with high Hb levels.
RESUMO
BACKGROUND: The efficacy and safety of each third-generation drug-eluting stent with ultrathin struts and advanced polymer technology remain unclear. We investigated the clinical outcomes of percutaneous coronary intervention using the Coroflex ISAR polymer-free sirolimus-eluting stent (SES) or Orsiro biodegradable polymer SES. METHODS: The HOST-IDEA trial (Harmonizing Optimal Strategy for Treatment of Coronary Artery Stenosis-Coronary Intervention With Next-Generation Drug-Eluting Stent Platforms and Abbreviated Dual Antiplatelet Therapy), initially designed with a 2×2 factorial approach, sought to randomize patients undergoing percutaneous coronary intervention based on dual antiplatelet therapy duration (3 versus 12 months) and stent type (Coroflex ISAR versus Orsiro). Despite randomizing 2013 patients for dual antiplatelet therapy duration, the stent arm transitioned to a registry format during the trial. Among these, 328 individuals (16.3%) were randomized for Coroflex ISAR or Orsiro SES, while 1685 (83.7%) underwent percutaneous coronary intervention without stent-type randomization. In this study, the Coroflex ISAR (n=559) and Orsiro groups (n=1449) were matched using a propensity score. The prespecified primary end point was target lesion failure, a composite of cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization at 12 months. RESULTS: The baseline patient and procedural characteristics were well balanced between the Coroflex ISAR and Orsiro groups after propensity score matching (n=559, each group). The Coroflex ISAR group was significantly associated with a higher rate of target lesion failure, mainly driven by clinically driven target lesion revascularization, compared with the Orsiro group (3.4% versus 1.1%; hazard ratio, 3.21 [95% CI, 1.28-8.05]; P=0.01). A higher risk of target lesion failure in the Coroflex ISAR group was consistently observed across various subgroups. The rates of any bleeding (hazard ratio, 0.85 [95% CI, 0.51-1.40]; P=0.52) and major bleeding (hazard ratio, 1.58 [95% CI, 0.61-4.08]; P=0.34) were comparable between the 2 groups. CONCLUSIONS: In this propensity score-matched analysis of the stent arm registry from the HOST-IDEA trial, the Orsiro SES was associated with significantly better outcomes in terms of 1-year target lesion failure, mainly driven by clinically driven target lesion revascularization, than the Coroflex ISAR SES.

BACKGROUND AND AIMS: Glomerular hyperfiltration (GHF) is a hemodynamic change of the kidney as an adaptive response to nephron loss. Although GHF is associated with metabolic risk factors and cardiovascular disease (CVD), the mechanisms that explain these relationships remain largely unknown. This is partially caused by a non-unified definition of GHF based on pathophysiologic vascular changes. Thus, the objective of this study was to evaluate the association between various definitions of GHF and carotid plaque in a health checkup cohort. METHODS: A total of 4493 individuals without history of CVD who had carotid ultrasonography (USG) results available between January 2016 and June 2018 were enrolled. GHF was defined as >90th percentile of eGFR residuals after adjusting for confounding factors. Carotid plaque score was calculated based on carotid USG results. RESULTS: Of 4493 individuals (mean age, 52.3 ± 10.1 years; 3224 [71.8%] males), 449 subjects were included in the GHF group (mean eGFR, 107.0 ± 7.1 ml/min/1.73 m2) and 4044 subjects were included in the non-GHF group (mean eGFR, 92.5 ± 12.3 ml/min/1.73 m2). When the GHF group was compared to the non-GHF group, GHF was associated with the presence of significant carotid plaque (carotid plaque score ≥2) (adjusted OR: 1.46; 95% CI: 1.16 to 1.83; p = 0.001). GHF defined in this study showed higher sensitivity to the presence of carotid plaque than other definitions of GHF. CONCLUSIONS: GHF status was associated with risk of carotid plaque in individuals without history of CVD. Presence of subclinical carotid plaque was associated with risk of future CVD. Therefore, GHF based on creatinine could be a useful surrogate marker for surveillance of CVD in asymptomatic individuals.

BACKGROUND: Drug-eluting stents significantly improved angiographic and clinical outcomes compared with bare metal stents in diabetic patients. However, a comparison of everolimus-eluting stents and sirolimus-eluting stents in diabetic patients has not been evaluated. Therefore we compared effectiveness of everolimus-eluting stents and sirolimus-eluting stents in patients with diabetes mellitus. METHODS AND RESULTS: This prospective, multicenter, randomized study compared everolimus-eluting stent (n=149) and sirolimus-eluting stent (n=151) implantation in diabetic patients. The primary end point was noninferiority of angiographic in-segment late loss at 8 months. Clinical events were also monitored for at least 12 months. Everolimus-eluting stents were noninferior to sirolimus-eluting stents for 8-month in-segment late loss (0.23 ± 0.27 versus 0.37 ± 0.52 mm; difference, -0.13 mm; 95% confidence interval, -0.25 to -0.02; upper 1-sided 95% confidence interval, -0.04; P<0.001 for noninferiority), with reductions in in-stent restenosis (0% versus 4.7%; P=0.029) and in-segment restenosis (0.9% versus 6.5%; P=0.035). However, in-stent late loss (0.11 ± 0.26 versus 0.20 ± 0.49 mm; P=0.114) was not statistically different between the 2 groups. At 12 months, ischemia-driven target lesion revascularization (0.7% versus 2.6%; P=0.317), death (1.3% versus 3.3%; P=0.448), and myocardial infarction (0% versus 1.3%; P=0.498) were not statistically different between the 2 groups. Major adverse cardiac events, including death, myocardial infarction, and ischemia-driven target lesion revascularization (2.0% versus 5.3%; P=0.218), were also not statistically different between the 2 groups. CONCLUSION: Everolimus-eluting stents were noninferior to sirolimus-eluting stents in reducing in-segment late loss and reduced angiographic restenosis at 8 months in patients with diabetes mellitus and coronary artery disease.

BACKGROUND: Recent studies have indicated that the triglyceride-glucose (TyG) index or subclinical thyroid dysfunction is associated with carotid plaques, a predictor of cardiovascular disease risk. However, evidence for this association is limited and inconsistent. This study aimed to evaluate the risk of carotid plaques according to TyG index and thyroid function status in the general population. METHODS: A total of 2,931 individuals who underwent carotid ultrasound as part of a comprehensive health examination at the Health Promotion Center of Soonchunhyang University Hospital were retrospectively reviewed. Based on the TyG index and thyroid function status, the participants were divided into six groups: LoTyG-SHyper (low TyG index with subclinical hyperthyroidism), LoTyG-Eu (low TyG index with euthyroidism), LoTyG-SHypo (low TyG index with subclinical hypothyroidism), HiTyG-SHyper (high TyG index with subclinical hyperthyroidism), HiTyG-Eu (high TyG index with euthyroidism), and HiTyG-SHypo (high TyG index with subclinical hypothyroidism). A multivariate logistic regression analysis was conducted to determine the risk of carotid plaques. RESULTS: The proportion of participants with significant carotid plaques was significantly different among the six groups (p<0.001, p for trend<0.001). The odds ratio (OR) and 95% confidence interval (CI) for significant carotid plaques were significantly higher in the HiTyG-SHypo group than in the LoTyG-Eu group, even after adjusting for confounding variables including sex, age, smoking, obesity, hypertension and diabetes mellitus (OR 1.506, 95% CI 1.045-2.170, p = 0.028). The OR of significant carotid plaques was higher in the HiTyG-Eu group than in the LoTyG-Eu group; however no associations were observed after additional adjustment for confounding variables. CONCLUSION: The TyG index and thyroid function status are important predictors of the risk of carotid plaques in healthy individuals. Early evaluation of carotid plaques may be necessary for subjects with high insulin resistance and subclinical hypothyroidism.

BACKGROUND: Stress cardiomyopathy (SCMP) is an acute but reversible heart failure syndrome with varying clinical outcomes. Although low triiodothyronine (T3) levels are closely associated with heart failure, it is uncertain whether total T3 levels on admission might be correlated with clinical outcomes in patients with SCMP. The aim of this study was to investigate the prognostic value of total T3 level for in-hospital mortality in patients with SCMP. METHODS: Patients presenting with SCMP at a single tertiary hospital between January 2013 and May 2019 were retrospectively reviewed. The diagnosis of SCMP was confirmed using the International Takotsubo Diagnostic Criteria and echocardiography was performed at least twice at the time of admission. Comorbidities, antecedent triggers, and other cardiac and metabolic parameters were measured in the survivor group compared with the non-survivor group. We evaluated the correlation between these parameters, especially total T3 and the prevalence of in-hospital mortality and the predictive values of total T3. RESULTS: Of the 134 SCMP patients (69.4 ± 15.5 years old, 94 women), 29 (21.6%) died during hospitalisation. The median follow-up period (interquartile range) was 480 days (63.25-1052.50). Total T3 levels were significantly lower in the non-survival group than in the survival group (33.38 ± 22.58 ng/dL vs. 65.72 ± 34.68 ng/dL, p < 0.0001). Receiver operating characteristic curve analysis showed the cut-offs of total T3 levels (≤64.37 ng/dL) for in-hospital mortality (area under curve [AUC] = 0.764, p < 0.001). In multivariable analysis, the T3 level (odds ratio [OR], 0.957; 95% confidential interval [CI], 0.934 to 0.982; p < 0.001), left ventricular ejection in follow-up echocardiography (OR, 0.935; 95% CI, 0.889-0.983; p = 0.008), and shock at initial presentation (OR, 3.389; 95% CI, 1.076-10.669; p = 0.037) were independent predictors for in-hospital mortality in SCMP patients. In patients with low T3 (<64.37 ng/dL), the 30-day survival rate was also significantly lower (81.58 vs. 100%, Log rank p = 0.001). CONCLUSIONS: Lower levels of total T3 were strongly correlated with in-hospital mortality in patients with SCMP. A low T3 level might suggest poor prognosis in patients with SCMP.

BACKGROUND: Patients on haemodialysis (HD) are at high risk of infective endocarditis (IE). Research comparing the microbiological features as well as clinical characteristics and outcomes of HD and non-HD patients with IE is limited. Specifically, no data focussed on vascular access infections (VAIs) have been reported. METHODS: The medical records of patients with IE were retrospectively reviewed from January 2010 to February 2020 in a referral hospital in Korea. Those with definite or possible IE by modified Duke criteria were included in the study. The clinical characteristics, microbiological features, echocardiographic findings and outcomes of the patients were analysed. RESULTS: Of the 80 patients with IE, 34 had undergone HD and 46 had not. HD patients with IE had a higher in-hospital mortality rate (50% vs. 17.4%, p = .004) than non-HD patients. In multivariable stepwise Cox proportional hazards regression analysis, HD (hazard ratio = 2.633; 95% confidential interval: 1.053-6.582; p = .038) was predictors of 60-day mortality in IE patients. In HD patients, the presence of VAI was associated with a high in-hospital mortality rate (70.59% vs. 29.41%, p = .039) and all of the patients with VAIs (100%) had methicillin-resistant S. aureus (MRSA) as a causative pathogen. CONCLUSIONS: HD patients with IE showed high in-hospital mortality. HD, high C-reactive protein levels and lower left ventricular ejection fraction were predictors of 60-day mortality in IE patients. In particular, HD patients with VAIs had higher mortality rates and MRSA should be considered as the causative microorganism.

BACKGROUND: Cardiac arrest during or after office-based cosmetic surgery is rare, and little is known about its prognosis. We assessed the clinical outcomes of patients who developed cardiac arrest during or after cosmetic surgery at office-based clinics. METHODS: Between May 2009 and May 2016, 32 patients who developed cardiac arrest during or after treatment at cosmetic surgery clinics were consecutively enrolled. We compared clinical outcomes, including complications, between survivors (n=19) and non-survivors (n=13) and attempted to determine the prognostic factors of mortality. RESULTS: All 32 of the patients were female, with a mean age of 30.40±11.87 years. Of the 32 patients, 13 (41%) died. Extracorporeal life support (ECLS) was applied in a greater percentage of non-survivors than survivors (92.3% vs. 47.4%, respectively; p=0.009). The mean duration of in-hospital cardiopulmonary resuscitation (CPR) was longer for the non-survivors than the survivors (31.55±33 minutes vs. 7.59±9.07 minutes, respectively; p=0.01). The mean Acute Physiology and Chronic Health Evaluation score was also higher among non-survivors than survivors (23.85±6.68 vs. 16.79±7.44, respectively; p=0.01). No predictor of death was identified in the patients for whom ECLS was applied. Of the 19 survivors, 10 (52.6%) had hypoxic brain damage, and 1 (5.3%) had permanent lower leg ischemia. Logistic regression analyses revealed that the estimated glomerular filtration rate was a predictor of mortality. CONCLUSION: Patients who developed cardiac arrest during or after cosmetic surgery at office-based clinics experienced poor prognoses, even though ECLS was applied in most cases. The survivors suffered serious complications. Careful monitoring of subjects and active CPR (when necessary) in cosmetic surgery clinics may be essential.
RESUMO
Obesity is associated with a high risk of morbidity and mortality in the general population and is a major independent risk factor for cardiovascular disease. We sought to evaluate the effect of overweight/obesity on clinical outcomes of patients with vasospastic angina (VA) at 1-year follow-up. The VA-KOREA (Vasospastic Angina in Korea) registry was a cohort of 11 centers from 2010 to 2015. The primary endpoint was a composite of cardiac death (CD), new-onset arrhythmia, and acute coronary syndrome (ACS). Using the body mass index (BMI) cut-off for Asians, 517 patients with definite VA were divided into either an overweight/obese (BMI ≥ 23 kg/m2) group (n = 378) or a normal weight (BMI 18.5-22.9 kg/m2) group (n = 139). The overweight/obese group showed a significantly lower rate of the primary endpoint composite (2.4% vs 7.9%, p = 0.004) and ACS (0.8% vs 4.3%, p = 0.007) than the normal weight group in the crude population. Similarly, in propensity-score matched analysis, the overweight/obese group showed a significantly lower rate of the primary endpoint composite (2.3% vs 8.4%, p = 0.006) and ACS (1.1% vs 4.6%, p = 0.035) than the normal weight group. However, there were no significant differences in CD and new-onset arrhythmia between the two groups in both the crude and propensity-score matched population. Independent predictors of the primary endpoint were overweight/obesity and dyslipidemia. In patients with VA, the overweight/obese group was associated with a favorable 1-year primary endpoint and the difference was mainly driven by the lower rate of ACS compared with the normal weight group.

INTRODUCTION: Although the implementation of transradial intervention (TRI) has increased over the last few years, there are limited data on the impact of TRI on efficacy and safety in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). We sought to compare one-year clinical outcomes and bleeding complications of TRI with those of transfemoral intervention (TFI) in patients with NSTE-ACS. METHODS: The Korean TRI registry was a cohort of 20 centres from 2012 to 2015. The primary efficacy endpoint was major adverse cardiovascular events (MACE), defined as a composite of cardiac death (CD), non-fatal myocardial infarction (MI) and repeat revascularisation (RR). Among the 1 319 patients with NSTE-ACS, 1 285 were finally analysed after excluding 34 due to lack of follow-up data. The patients were divided into TRI and TFI groups according to the final access site. RESULTS: At one-year follow up, the TRI group showed a significantly lower rate of MACE, and a marginally significantly lower rate of CD than the TFI group in the crude population. However, in propensity-score matched analysis, the rate of MACE did not differ between the TRI and TFI groups. Regarding bleeding complications, the TRI group was associated with significantly lower rates of major bleeding in both the crude and matched populations. Independent predictors of MACE were chronic kidney disease (CKD) and multi-vessel disease (MVD). CONCLUSIONS: In patients with NSTE-ACS, TRI was associated with favourable one-year clinical outcomes and lower bleeding complications compared to TFI. Independent predictors of MACE were clinical and angiographic profiles (CKD, MVD) rather than vascular access sites.

Extracorporeal life support (ECLS) has recently been reported to have a survival benefit in patients with cardiac arrest. It is now used widely as a lifesaving modality. Here, we describe a case of sudden cardiac arrest (SCA) in a young athlete with an anomalous origin of the right coronary artery from the left coronary sinus. Resuscitation was successful using ECLS before curative bypass surgery. We highlight the efficacy of ECLS for a patient with SCA caused by a rare, unexpected aetiology. In conclusion, ECLS was a lifesaving modality for SCA due to an anomalous coronary artery in this young patient.
RESUMO
BACKGROUND: The role of asthma status and characteristics of asthma in the risk of myocardial infarction (MI) are poorly understood. OBJECTIVE: We determined whether asthma and its characteristics are associated with risk of MI. METHODS: The study was designed as a population-based retrospective case-control study, which included all eligible incident MI cases between November 1, 2002, and May 31, 2006, and their matched controls. Asthma was ascertained using predetermined criteria. Active (current) asthma was defined as the occurrence of asthma-related episodes (asthma symptoms, use of asthma medications, unscheduled medical or emergency department visit, or hospitalization for asthma) within 1 year before MI index date. RESULTS: There were 543 eligible incident MI cases during the study period. Of the 543 MI cases, 81 (15%) had a history of asthma before index date of MI, whereas 52 of 543 controls (10%) had such a history (adjusted odds ratio [OR]: 1.68; 95% CI: 1.06-2.66) adjusting for risk factors for MI and comorbid conditions (excluding chronic obstructive lung disease). Although inactive asthma did not increase the risk of MI, individuals with active asthma had a higher odds of MI, compared with those without asthma (adjusted OR: 3.18; 95% CI: 1.57-6.44) without controlling for chronic obstructive pulmonary disease (COPD). After adjusting for COPD, although asthma overall was no longer statistically significant (adjusted OR: 1.34, 95% CI: 0.84-2.15), active asthma still was associated (adjusted OR: 2.33, 95% CI: 1.12-4.82). CONCLUSION: Active asthma is an unrecognized risk factor for MI. Further studies are needed to assess the role of asthma control and medications in the risk of MI.

A thromboembolic complication such as pulmonary embolism in patients who had cancer and mobile thrombi in the heart is a rare but fatal complication. Surgical thromboembolectomy is considered as the classical treatment of choice. In case of inoperable patient, catheter-directed therapy may be an alternative treatment. We report an interesting case of metastatic breast cancer with a large and mobile right atrial thrombus complicated by a massive and subsequently recurring pulmonary embolism, followed by thrombocytopenia developed after heparin and warfarin treatment.

Polycystic kidney disease (PCKD) is rarely associated with aortic dissection (AD), which is a life-threatening disease. Although endovascular stent-graft repair tends to show better outcomes than conventional therapies in complicated type B AD (TBAD), successful endovascular intervention of TBAD with malperfusion in a patient with PCKD has not been reported. This case shows a 37-year-old male who had sudden onset of sharply stabbing epigastric pain with severe hypertension, who was diagnosed with TBAD and PCKD by a computed tomography and initially underwent medical treatment. Four days after discharge, he was rehospitalized with left leg pain and paresthesia due to left lower leg malperfusion. Thoracic endovascular stent-graft repair covering the primary tear site of dissection was performed successfully, leading to a decrease in false lumen and improvement of symptoms. We report the case of complicated TBAD in a patient with PCKD treated with endovascular stent-graft repair.
RESUMO
BACKGROUND: To assess whether the individual housing-based socioeconomic status (SES) measure termed HOUSES was associated with post-myocardial infarction (MI) mortality. METHODS: The study was designed as a population-based cohort study, which compared post-MI mortality among Olmsted County, Minnesota, USA, residents with different SES as measured by HOUSES using Cox proportional hazards models. Subjects' addresses at index date of MI were geocoded to real property data to formulate HOUSES (a z-score for housing value, square footage, and numbers of bedrooms and bathrooms). Educational levels were used as a comparison for the HOUSES index. RESULTS: 637 of the 696 eligible patients with MI (92%) were successfully geocoded to real property data. Post-MI survival rates were 60% (50-72), 78% (71-85), 72% (60-87), and 87% (81-93) at 2 years for patients in the first (the lowest SES), second, third, and fourth quartiles of HOUSES, respectively (p < 0.001). HOUSES was associated with post-MI all-cause mortality, controlling for all variables except age and comorbidity (p = 0.036) but was not significant after adjusting for age and comorbidity (p = 0.24). CONCLUSIONS: Although HOUSES is associated with post-MI mortality, the differential mortality rates by HOUSES were primarily accounted for by age and comorbid conditions. HOUSES may be useful for health disparities research concerning cardiovascular outcomes, especially in overcoming the paucity of conventional SES measures in commonly used datasets.

OBJECTIVES: Asthmatics have increased risks of airway-related infections. Little is known about whether this is true for non-airway-related serious infections such as Escherichia coli bloodstream infection (BSI). We assessed whether asthma is associated with a risk of developing community-acquired E coli BSI. DESIGN: The study was designed as a population-based retrospective case-control study. SETTING: This population-based study was conducted in Olmsted County, Minnesota. PARTICIPANTS: The study included 259 all eligible community-acquired E coli BSI cases in Olmsted County, MN between 1998 and 2007 and 259 birthday-matched, gender-matched and residency-matched controls. PRIMARY AND SECONDARY OUTCOME MEASURES: Only community-acquired E coli BSI cases as the primary outcome was included. Asthma status as an exposure was ascertained by predetermined criteria. An adjusted OR and 95% CI for the association between asthma and risk of community-acquired E coli BSI was calculated using conditional logistic regression. RESULTS: Of 259 eligible cases, 179 (69%) were women and mean age was 61±22 years. Of the 259 cases 37 (14%) and 16 (6%) of 259 controls had a prior history of asthma (adjusted OR 2.74; 95% CI 1.11 to 6.76; p=0.029). The population attributable risk of asthma for community-acquired E coli BSI was 9%. Although not statistically significant, there was a borderline association between having a history of food allergy and increased risk of community-acquired E coli BSI (6% vs 2%; adjusted OR 3.51; 95% CI 0.94 to 13.11; p=0.062). CONCLUSIONS: Based on the findings of the current population-based, case-control investigation, a history of asthma may be associated with risk of community-acquired E coli BSI. The impact of asthma on risk of microbial infections may go beyond airways.
