RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND AND PURPOSE: Left ventricular diastolic dysfunction (LVDD) is a predictor for atrial fibrillation (AF). This study was aimed to investigate whether LVDD in cryptogenic ischemic stroke (CS) could be a clue to stroke mechanism. METHODS: The clinical and echocardiographic findings of 1589 consecutive patients with acute ischemic stroke or transient ischemic attack between 2004 and 2013 were reviewed. LVDDs among stroke subtypes were graded by transthoracic echocardiography into 4 groups by severity: normal, abnormal relaxation (grade I), pseudonormal (grade II), and restrictive diastolic filling (grade III), whereas severe LVDD was defined as grade III. We classified the lesion pattern of CS into cardioembolism-mimic or non-cardioembolism-mimic and determined whether cardioembolism-mimic lesions were associated with severe LVDD. RESULTS: The fraction of severe LVDD in CS was not different from that of stroke with AF (27.3% versus 37.1%; P=0.173) but was significantly higher than that of stroke without AF (27.3% versus 13.4%; P=0.008). Cardioembolism-mimic CS had more severe LVDD than non-cardioembolism-mimic CS (41.4% versus 11.5%; P=0.013). LVDD of grade II (odds ratio, 4.37; 95% confidence interval, 2.99-6.41) and grade III (odds ratio, 5.60; 95% confidence interval, 3.42-9.17) were independently related to stroke with AF after adjusting covariates. CONCLUSIONS: The severe LVDD could be a predictor of stroke with AF, and its frequency was similar between CS and stroke with AF. Cardioembolism-mimic CS had significantly more severe LVDD than non-cardioembolism-mimic CS. LVDD could be helpful to discriminate the stroke mechanism in the patients with acute CS.

RESUMO

PURPOSE: To investigate the predictors of failed false lumen (FL) volume reduction at 12 months after stent-graft implantation in patients with type B aortic dissection. METHODS: The retrospective analysis comprised 38 patients (25 men; mean age 60±12 years) with double-barrel type B aortic dissection (9 acute) treated with thoracic endovascular aortic repair (TEVAR) and evaluated with serial computed tomography (CT) scans up to 12 months. Aortic volume changes were determined. Based on FL volume change at 1 year after stent-graft implantation, patients were dichotomized according to the presence or absence of FL volume reduction. Clinical and CT variables were compared between groups to determine risk factors of failed FL volume reduction. A major adverse event (MAE) was defined as death or reintervention. RESULTS: Patients were followed for 4.2±2.8 years. FL volume reduction (+FLVR) occurred in 27 (71%) patients, whereas 11 (29%) patients had no FL volume reduction (-FLVR). The MAE-free survival rate was significantly higher in the +FLVR patients than in the -FLVR group (88.9% vs. 27.3%, respectively; p=0.001). Chronicity of dissection, location of tear site, or the maximum total aortic lumen area was not associated with failure to achieve FL volume reduction. However, the maximum preprocedure FL area was significantly lower in the +FLVR group than in the -FLVR group (12.6±6.6 vs. 21.0±11.4 cm(2), respectively; p=0.041) and was an independent predictor for failed FL volume reduction (odds ratio 1.3, 95% confidence interval 1.02 to 1.70, p=0.031). CONCLUSION: Failed FL volume reduction after TEVAR was associated with a significantly increased rate of mortality or reintervention during follow-up. A larger preprocedure maximum FL area was a predictor of failed FL volume reduction after TEVAR in type B dissection.

RESUMO

INTRODUCTION: Inappropriate antiplatelet therapy discontinuation increases the risk of thrombotic complications and bleeding after dental procedures. To determine the platelet reactivity recovery time after aspirin withdrawal in vivo, our study was conducted in patients with low-risk cardiovascular disease who can stop aspirin administration following the guidelines stipulated by the American College of Chest Physicians. The time it takes for platelet activity to normalize and the diagnostic accuracy of testing methods were assessed for a residual antiplatelet activity with multiple electrode aggregometry. Our study included patients with clinically indicated hypertension preparing for a dental extraction procedure. MATERIALS AND METHODS: A total of 212 patients not taking aspirin (control group) and 248 patients with hypertension receiving long-time aspirin treatment at a 100-mg daily dose were prospectively included in the study, which involved stopping aspirin intake before dental extraction. The residual platelet activity and dental bleeding in patients who stopped aspirin intake were analyzed and compared with those of the control group. In addition, platelet reactivity recovery time and bleeding risk in patients who stopped taking aspirin every 24 hours for 0 to 5 days (0-143 hours) before dental extraction was also assessed. RESULTS: Platelet reactivity normalized 96 hours after aspirin withdrawal. The cut-off value of 49 arbitrary units in the arachidonic acid platelet aggregation test excluded the effect of aspirin with 91% sensitivity and 66% specificity. AUC showed 0.86 (P < 0.001) diagnostic accuracy. The immediate bleeding complications in all treatment groups were similar to those seen in the control group and were successfully managed with local hemostatic measures. CONCLUSIONS: The antiplatelet effects of aspirin disappeared 96 hours after aspirin withdrawal in our study, and dental extractions may be safely performed in this period when appropriate local hemostatic measures are taken. Based on these results, a shorter aspirin intake cessation period may be allowable in complex dental procedures and surgery for which a longer aspirin intake cessation period (7-10 days) is recommended based on the American College of Chest Physicians guidelines.

RESUMO

BACKGROUND: The second-generation drug-eluting stents (DES) have shown superiority in many studies relating to safety and efficacy when compared with the first-generation DES. However, it is unclear whether there are differences in efficacy and safety among the second-generation DES after long-term follow-up. METHODS: This multicenter, prospective, randomized, open-labeled trial will directly compare the efficacy and safety among the patients treated with either everolimus-eluting stent (EES), zotarolimus-eluting stent with biolinx polymer (ZES-R), or biolimus-eluting stent (BES) with minimal exclusion criteria. The primary end point is a patient-oriented composite consisted of cardiac death, myocardial infarction not clearly attributable to a nontarget vessel and clinically indicated target lesion revascularization at 24-month clinical follow-up post-index procedure. With the hypothesis that "BES is non-inferior to EES" or "BES is non-inferior to ZES-R" in primary end point, approximately 2,600 patients will be assigned to one of the types of stents using a web-based randomization system. CONCLUSIONS: The CHOICE trial will directly compare the efficacy and safety of EES, ZES-R, and BES in everyday clinical practice for long-term follow-up.

RESUMO

AIMS: Paclitaxel-eluting stents (PESs) have been shown to inhibit neointimal hyperplasia after percutaneous coronary intervention. Coroflex Please (B Braun, Melsungen, Germany) is a newly developed PES. We compared the clinical and angiographic efficacy of Coroflex Please with Taxus Liberte (Boston Scientific, Natick, MA) in a real-world practice. METHODS AND RESULTS: We performed a prospective, open-label, randomized, controlled study that enrolled 945 patients undergoing percutaneous coronary interventions in 18 centers in Korea. The primary end point was clinically driven target vessel revascularization at 9 months. The baseline characteristics were mostly similar and comparable between 2 groups. At 9 months, the incidence of clinically driven target vessel revascularization was 14.6% for Coroflex and 6.4% for Taxus, which was significantly different (hazard ratio 2.43, 95% CI 1.50-3.94, noninferiority P value = 1.000). This is well corroborated by the difference of in-stent late loss between 2 stents (0.71 ± 0.64 mm vs 0.52 ± 0.50 mm, P < .001) by 9-month follow-up angiography (n = 415 vs 215). Among secondary clinical end points, stent thrombosis (definite and probable) for 1 year was 2.2% in Coroflex and 1.3% in Taxus (P = .317). Also, myocardial infarction for 9 months was higher in Coroflex group than that in Taxus (4.9% vs 1.6%, P = .012), which was partly contributed by the higher incidence of periprocedural myocardial infarction in Coroflex arm (2.2% vs 0.3%, P = .028). CONCLUSIONS: Coroflex Please was inferior to Taxus Liberte with regard to clinical and angiographic efficacy.

RESUMO

The authors evaluated the efficacy, safety, and characteristics of patients who respond well to standard dose triple combination therapy including chlorthalidone 25 mg with telmisartan 80 mg plus amlodipine 5 mg in hypertensive patients. This is a multicenter, double-blind, active-controlled, phase 3, randomized trial. Patients are randomized to triple combination (telmisartan 40 mg/amlodipine 5 mg/chlorthalidone 12.5 mg, TEL/AML/CHTD group) or dual combination (telmisartan 40 mg/amlodipine 5 mg, TEL/AML group) treatment and then dose up titration to TEL 80/AML5/CHTD25mg and TEL80/AML5, respectively. The primary endpoint is the change of mean sitting systolic blood pressure (MSSBP) at week 8. A Target BP achievement rate, a response rate, and the safety endpoints are also evaluated. Total 374 patients (mean age = 60.9 ± 10.7 years, male = 78.3%) were randomized to the study. The baseline MSSBPs/diastolic BPs were 149.9 ± 12.2/88.5 ± 10.4 mm Hg. After 8 weeks treatment, the change of MSSBPs at week 8 are -19.1 ± 14.9 mm Hg (TEL/AML/CHTD) and -11.4 ± 14.7 mm Hg (TEL/AML) (p < .0001). The achievement rates of target BP (53.8% vs. 37.8%, p = .0017) and responder rate (54.8% vs. 35.6%, p = .0001) at week 8 were significantly higher in TEL/AML/CHTD. There are no serious adverse event and no one discontinued medication due to adverse event. Among the TEL 80/AML5/CHTD25mg treatment group, patients of female or age ≥ 65 years old showed higher rate of target BP achievement than relatively young male. (61.4 vs. 46.8%, p = .042) Our study showed standard dose triple combination of telmisartan 80 mg/amlodipine 5 mg/chlorthalidone 25 mg is efficacious and safe in treatment of primary hypertension. Target BP achievement with triple therapy would be facilitated in female or old age.

RESUMO

The authors performed this study to investigate the efficacy and safety of a rosuvastatin (RSV)/amlodipine (AML) polypill compared with those of atorvastatin (ATV)/AML polypill. We included 259 patients from 21 institutions in Korea. Patients were randomly assigned to 1 of 3 treatment groups: RSV 10 mg/AML 5 mg, RSV 20 mg/AML 5 mg, or ATV 20 mg /AML 5 mg. The primary endpoint was the efficacy of the RSV 10.20 mg/AML 5 mg via percentage changes in LDL-C after 8 weeks of treatment, compared with the ATV 20 mg /AML 5 mg. There was a significant difference in the mean percentage change of LDL-C at 8 weeks between the RSV 10 mg/AML 5 mg and the ATV 20 mg/AML 5 mg (full analysis set [FAS]: -7.08%, 95% CI: -11.79 to -2.38, p = .0034, per-protocol analysis set [PPS]: -6.97%, 95% CI: -11.76 to -2.19, p = .0046). Also, there was a significant difference in the mean percentage change of LDL-C at 8 weeks between the RSV 20 mg/AML 5 mg and the ATV 20 mg/AML 5 mg (FAS: -10.13%, 95% CI: -15.41 to -4.84, p = .0002, PPS: -10.96%, 95% CI: -15.98 to -5.93, p < .0001). There was no significant difference in the adverse events rates between RSV 10 mg/AML 5 mg, RSV 20 mg/AML 5 mg, and ATV 20 mg/AML 5 mg. In conclusion, while maintaining safety, RSV 10 mg/AML 5 mg and the RSV 20 mg/AML 5 mg more effectively reduced LDL-C compared with the ATV 20 mg /AML 5 mg (Clinical trial: NCT03951207).

RESUMO

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.

RESUMO

Public reporting is a way to promote quality of healthcare. However, evidence supporting improved quality of care using public reporting in patients with acute myocardial infarction (AMI) is disputed. This study aims to describe the impact of public reporting of AMI care on hospital quality improvement in Korea. Patients with AMI admitted to the emergency room with ICD-10 codes of I21.0 to I21.9 as the primary or secondary diagnosis were identified from the national health insurance claims data (2007-2012). Between 2007 and 2012, 43,240/83,378 (51.9%) patients manifested ST segment elevation myocardial infarction (STEMI). Timely reperfusion rate increased (ß = 2.78, p = 0.001). The mortality rate of STEMI patients was not changed (ß = -0.0098, p = 0.384) but that of NSTEMI patients decreased (ß = -0.465, p = 0.001). Public reporting has a substantial impact on the process indicators of AMI in Korea because of the increased reperfusion rate. However, the outcome indicators such as mortality did not significantly change, suggesting that public reporting did not necessarily improve the quality of care.

RESUMO

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.

RESUMO

Venous thromboembolism (VTE) is a potentially serious complication after total knee replacement (TKR), and recent guideline recommends thromboprophylaxis for VTE after TKR. The neutrophil-lymphocyte ratio (NLR) has emerged as a simple and new prognostic biomarker for several cardiovascular diseases. This study was performed to investigate the precise incidence of postoperative VTE and the role of NLR for predicting VTE in patients receiving thromboprophylaxis after TKR. We retrospectively enrolled 264 patients undergoing TKR who underwent routine screening enhanced pulmonary artery and lower extremity venography computed tomography (CT) scan within 7 postoperative days. Biochemical tests were performed within 2 weeks prior to surgery, and the NLR was defined as the absolute neutrophil count in peripheral blood divided by lymphocyte count. All patients received thromboprophylaxis with enoxaparin postoperatively. Of 264 patients, 102 (38.6%) were diagnosed with deep vein thrombosis (DVT) or pulmonary embolism on CT scan. Preoperative NLR was significantly higher in patients with postoperative VTE compared with that in patients without VTE (2.57 ± 1.59 vs. 2.11 ± 1.10, p = 0.011). Receiver operating characteristic curve analysis showed that a preoperative NLR of 1.90 was the best cutoff value for the prediction of postoperative VTE (sensitivity 57.8%, specificity 55.6%, and area under curve 0.589). In the multivariate analysis, a preoperative NLR ≥1.90 was a sole independent predictor of postoperative VTE (odds ratio: 1.95, 95% computed tomography: 1.16-3.31, p = 0.013). The present study shows a higher incidence of VTE (38.6%) after TKR in patients receiving thromboprophylaxis than that reported in previous studies. Furthermore, preoperative NLR was significantly higher in patients with postoperative VTE, and a high preoperative NLR (≥1.90) was an independent predictor of VTE after TKR. NLR measurement may be a simple and useful method for the prediction of VTE in patients undergoing TKR.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND AND OBJECTIVES: The relationship between the hospital percutaneous coronary intervention (PCI) volumes and the in-hospital clinical outcomes of patients with acute myocardial infarction (AMI) remains the subject of debate. This study aimed to determine whether the in-hospital clinical outcomes of patients with AMI in Korea are significantly associated with hospital PCI volumes. METHODS: We selected and analyzed 17,121 cases of AMI, that is, 8,839 cases of non-ST-segment elevation myocardial infarction and 8,282 cases of ST-segment elevation myocardial infarction, enrolled in the 2014 Korean percutaneous coronary intervention (K-PCI) registry. Patients were divided into 2 groups according to hospital annual PCI volume, that is, to a high-volume group (≥400/year) or a low-volume group (<400/year). Major adverse cardiovascular and cerebrovascular events (MACCEs) were defined as composites of death, cardiac death, non-fatal myocardial infarction (MI), stent thrombosis, stroke, and need for urgent PCI during index admission after PCI. RESULTS: Rates of MACCE and non-fatal MI were higher in the low-volume group than in the high-volume group (MACCE: 10.9% vs. 8.6%, p=0.001; non-fatal MI: 4.8% vs. 2.6%, p=0.001, respectively). Multivariate regression analysis showed PCI volume did not independently predict MACCE. CONCLUSIONS: Hospital PCI volume was not found to be an independent predictor of in-hospital clinical outcomes in patients with AMI included in the 2014 K-PCI registry.

RESUMO

BACKGROUND: There is limited data comparing the Xience everolimus-eluting stent (EES) and the Resolute zotarolimus-eluting stent (ZES) with the BioMatrix biolimus-eluting stent (BES). METHODS: This open-label, randomized, noninferiority trial enrolled all-comer patients to be randomly treated with either BES, EES, or ZES in a 1:1:1 ratio in 15 centers across South Korea. The primary end point was a device-oriented composite outcome consisting of cardiac death, target-vessel myocardial infarction, and clinically indicated target lesion revascularization at 24 months. The BES was compared with the EES and the ZES by intention-to-treat analyses with a noninferiority margin of 3.8%, respectively. RESULTS: Because of slow recruitment and low event rates, this trial was prematurely terminated after enrollment of 1935 (75%) of the intended 2580 patients. Of the 1911 patients randomized to either EES (n=638), BES (n=634), or ZES (n =639), the rate of device-oriented composite outcome was 3.6%, 2.2%, and 3.9%, respectively, at 24 months (BES versus EES: absolute risk difference -1.4% [upper limit of 1-sided 95% CI: -3.2%]; Pfor noninferiority <0.001; BES versus ZES: absolute risk difference -1.7% [upper limit of 1-sided 95% CI: -3.6%]; Pfor noninferiority <0.001). CONCLUSIONS: The BES was noninferior to either the EES or the ZES in all-comer patients for device-oriented composite outcome at the 24-month follow-up. However, caution is advised regarding interpretation of these results due to the premature termination of this study.

RESUMO

Single risk factors, such as hypertension and dyslipidemia, can combine to exacerbate the development and severity of cardiovascular disease. Treatment goals may be more effectively achieved if multiple disease factors are targeted with combination treatment. We enrolled 202 patients who were randomly divided into the following three groups: telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg, telmisartan 80 mg + rosuvastatin 20 mg, and telmisartan/amlodipine 80/5 mg. The primary efficacy variables were changes from baseline in mean sitting systolic blood pressure (MSSBP) between telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan 80 mg + rosuvastatin 20 mg at 8 weeks, and the percent changes from baseline in low-density lipoprotein (LDL) cholesterol between telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan/amlodipine 80/5 mg at 8 weeks. The secondary efficacy variables were changes in MSSBP, mean sitting diastolic blood pressure (MSDBP), LDL cholesterol and other lipid levels at 4 weeks and 8 weeks, as well as observed adverse events during follow-up. There were no significant differences between the three groups in demographic characteristics and no significant difference among the three groups in terms of baseline characteristics for the validity evaluation variables. The mean overall treatment compliance in the three groups was, respectively, 98.42%, 96.68%, and 98.12%, indicating strong compliance for all patients. The Least-Square (LS) mean (SE) for changes in MSSBP in the two (telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan 80 mg + rosuvastatin 20 mg) groups were -19.3 (2.68) mm Hg and -6.69 (2.76) mm Hg. The difference between the two groups was significant (-12.60 (2.77) mm Hg, 95% CI -18.06 to -7.14, P < .0001). The LS Mean for the percent changes from baseline in LDL cholesterol in the two (telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan/amlodipine 80/5 mg) groups were -52.45 (3.23) % and 2.68 (3.15) %. The difference between the two groups was significant (-55.13 (3.20) %, 95% CI -61.45 to -48.81, P < .0001). There were no adverse events leading to discontinuation or death. Combined administration of telmisartan/amlodipine 80/5 mg and rosuvastatin 20 mg for the treatment of hypertensive patients with dyslipidemia significantly reduces blood pressure and improves lipid control.

RESUMO

PURPOSE: Fixed-dose combination therapy with telmisartan, amlodipine, and rosuvastatin is needed in patients with hypertension and dyslipidemia for better adherence and cost-effectiveness than free-equivalent combination therapies. This study aimed to compare the efficacy and safety of combination therapy with telmisartan, amlodipine, and rosuvastatin versus telmisartan plus amlodipine or telmisartan plus rosuvastatin in patients with hypertension and dyslipidemia. METHODS: The Jeil Telmisartan, Amlodipine, and Rosuvastatin Randomized Clinical Trial (J-TAROS-RCT) was an 8-week, multicenter, randomized, double-blind, parallel, Phase III clinical trial conducted at 9 hospitals in Korea. After a run-in period of >4 weeks, patients who fulfilled the criteria of the National Cholesterol Education Program Adult Treatment Panel III guidelines were eligible for randomization to receive 1 of 3 treatments for 8 weeks: (1) telmisartan/amlodipine 80 mg/10 mg plus rosuvastatin 20 mg, (2) telmisartan/amlodipine 80 mg/10 mg, or (3) telmisartan 80 mg plus rosuvastatin 20 mg. The primary end point was efficacy evaluation of combination therapy with telmisartan/amlodipine/rosuvastatin by comparing the change in mean sitting systolic blood pressure (msSBP) and mean percentage change in LDL-C from baseline after 8 weeks of treatment. Adverse events (AEs), clinical laboratory data, and vital signs were assessed in all patients. FINDINGS: Among 148 patients, the changes in msSBP from baseline after 8 weeks of treatment were a mean (SD) of -24.41 (2.38) versus -9.31 (2.36) mm Hg in the telmisartan/amlodipine/rosuvastatin and telmisartan/rosuvastatin groups, respectively. Significantly more participants achieved the target BP at week 8 in the telmisartan/amlodipine/rosuvastatin group (41 patients [87.2%]) than in the telmisartan/rosuvastatin group (24 [50.0%], P < 0.001). The changes in mean (SD) LDL-C at 8 weeks compared with baseline values were -57.59% (11.59%) versus 6.08% (20.98%) in the telmisartan/amlodipine/rosuvastatin and telmisartan/amlodipine groups, respectively. The percentages of patients who achieved the target LDL-C according to their risk factors after 8 weeks of treatment were 97.87% vs 6.12% in the telmisartan/amlodipine/rosuvastatin and the telmisartan/amlodipine groups (P < 0.0001), respectively. No significant differences were found in the incidence of overall AEs and adverse drug reactions, and serious AEs were comparable among 3 groups. IMPLICATIONS: Fixed-dose combinations of telmisartan, amlodipine, and rosuvastatin decreased BP and LDL-C in patients with hypertension and dyslipidemia. The safety and tolerability profiles of fixed-dose telmisartan, amlodipine, and rosuvastatin combination therapy were comparable with those of telmisartan plus amlodipine or telmisartan plus rosuvastatin.
