Feasibility and safety of the antecubital venous access for right heart catheterization in patients with pulmonary hypertension.

BACKGROUND: The diagnosis of pulmonary arterial hypertension requires right heart catheterization (RHC) which is typically performed via proximal venous access (PVA). Antecubital venous access (AVA) is an alternative approach for RHC that can minimize complications, decrease procedural duration and allow for immediate patient recovery. A direct comparison between the two procedures in patients with pulmonary hypertension (PH) is lacking. OBJECTIVES: To determine the feasibility, safety, and adoption rates of AVA-RHC as compared with ultrasound-guided PVA in a subpopulation of patients with PH. METHODS: All patients who underwent RHC for evaluation of PH between December 2014 and March 2017 at a single large academic medical center were included in this study. Demographic, procedural and outcomes data were retrieved from the medical records. RESULTS: In total, 159 RHC were included (124 AVA, 35 PVA). The duration of RHC was significantly shorter in the AVA compared with PVA group (53 (IQR 38-70) vs. 80 (IQR 56-95) min, respectively, p < 0.001). 19% of AVA (24/124) procedures were switched to PVA. Failed attempts at AVA were more common in scleroderma (50% failure rate). Success rate of AVA increased from 81.2% to 93.3% from the first to last quartile. Fluoroscopy time was similar in both groups, the difference between the groups in the radiation dose are not statistically significant (54.5 (IQR 25-110) vs. 84.5 (IQR 30-134)). CONCLUSION: AVA-RHC is a feasible and safe alternative to PVA in patients with PH who are evaluated for pulmonary arterial hypertension diagnosis. Our experience and rapid adoption rate support the use of AVA as the preferred access site for RHC in uncomplicated PH patients.

Characteristics and outcomes of patients with cancer presenting with acute myocardial infarction.

BACKGROUND: Limited data are available regarding the optimal management of patients with cancer in the acute myocardial infarction (AMI) setting. PATIENTS AND METHODS: We studied consecutive patients with AMI included in a national registry (years 2010, 2016) with the diagnosis of past or active malignancy and followed them for 1 year. RESULTS: Our cohort consisted of 2937 cancer-naive patients and 152 patients with cancer, of whom 35% presented with active malignancies. Compared with cancer-naive patients, patients with cancer were older, with female predominance, and presented more often with a history of hypertension and chronic kidney disease (P<0.001 for all comparisons). The rate of ST-elevation AMI was comparable (P=0.067). GRACE score more than 140 was more common in the cancer group (P<0.001). Most patients with cancer were referred to coronary angiography, though less than cancer-naive patients (87 vs. 93%; P=0.004). The rate of percutaneous coronary intervention was similar (P=0.265). Propensity score matching demonstrated similar rates of in-hospital complications between groups, and no mortality or major cardiac adverse event differences were noted at 30 days. Moreover, short-term mortality was similar between patients with active versus past malignancies, and between patients with solid and nonsolid tumors. However, cancer in patients with AMI was found to predict an increased mortality risk at 1 year by multivariable analysis (hazard ratio=2.52; P<0.001). CONCLUSION: Patients with cancer and AMI have a more complicated clinical presentation, yet their short-term prognosis is similar to cancer-naive patients. Nevertheless, 1-year outcome is worse.

Feasibility and safety of exclusive echocardiography-guided intravenous temporary pacemaker implantation.

BACKGROUND: The standard approach for urgent trans-venous temporary cardiac pacemaker (TVTP) implantation is fluoroscopy guidance. The delay in activation of the fluoroscopy-room and the transfer of unstable patients may be life-threatening. Echocardiography-guided TP implantation may increase the safety of the patients by obviating the need for in-hospital transfer. We examined the feasibility and safety of echocardiography-guided vs. fluoroscopy-guided TVTP implantation. METHODS: From January 2015 to September 2017 data for consecutive patients who needed emergent TVTP implantation were retrospectively reviewed. Ultrasound-guided TVTP protocol that was introduced in our center in January 2015 involved ultrasound guidance for both central venous access and pacing lead positioning. Access sites included femoral, subclavian, or jugular veins. Electrodes were placed in the right ventricular apex by means of echocardiographic monitoring in intensive care unit or by fluoroscopic guidance. Endpoints were achievement of successful ventricular pacing and procedural complications. RESULTS: Sixty-six patients (17 echocardiography-guided and 49 fluoroscopy-guided) were included. There were no differences in pacing threshold between the echocardiography-guided group and the fluoroscopy-guided group (0.75 ± 0.58 mA vs. 0.57 ± 0.35 mA, p = 0.24). The access site for implantation was femoral vein in 27% for the fluoroscopy-guided vs. none for the echocardiography-guided approach (p = 0.015). One hematoma and one related infection occurred in the fluoroscopy-guided group. The need for electrode repositioning was observed in 1 patient in each group. There were no procedural-related deaths in either group. CONCLUSIONS: Echocardiography-guided temporary cardiac pacing is a feasible and safe alternative to fluoroscopy-guided approach and significantly lowers the need for in-hospital transfer.

Serial imaging after pulmonary embolism and correlation with functional limitation at 12 months: Results of the ELOPE Study.

INTRODUCTION: Risk factors for exercise limitation after acute pulmonary embolism (PE) are unknown. As a planned sub-study of the prospective, multicenter ELOPE (Evaluation of Long-term Outcomes after PE) Study, we aimed to describe the results of serial imaging by computed tomography pulmonary angiography (CTPA) and perfusion scan during 1 year after a first episode of acute pulmonary embolism, and to assess the association between imaging parameters and exercise limitation at 1 year. METHODS: In a prospective cohort study, 100 patients were recruited between June 2010 and February 2013 at five Canadian university-affiliated hospitals. CT pulmonary angiography was performed at baseline and 12 months, perfusion scan at 6 and 12 months, and cardio-pulmonary exercise testing at 1 and 12 months. Imaging parameters included: on CT pulmonary angiography, CT obstruction index (CTO) (% clot burden in the pulmonary vasculature), and on perfusion scan, pulmonary vascular obstruction (PVO) (% perfusion defect). Abnormal cardio-pulmonary exercise test (primary outcome) was defined as percent of predicted peak oxygen uptake (VO2) <80%. RESULTS: Mean (median; SD) CT obstruction index was 28.1% (27.5%; 18.3%) at baseline, 1.2% (0%; 4.3%) at 12 months. Mean (median; SD) pulmonary vascular obstruction was 6.0% (0%; 9.6%) at 6 months, 5.6% (0%; 9.8%) at 12 months. Eighty-six patients had exercise testing at 12 months, and 46.5% had VO2 < 80% predicted. Mean (median; SD) CT obstruction index at 1 year was similar in patients with percent-predicted VO2 peak <80% vs >80% on 1-year cardio-pulmonary exercise testing (1.4% [0%; 5.7%] vs 1.0% [0%; 2.4%]; P = .70). Mean (SD) pulmonary vascular obstruction at 6 and at 12 months was similar in patients with percent-predicted VO2 peak <80% vs >80% (6 months: 5.9% [0%; 10.4%] vs 6.2% [4.5%; 9.0%]; P = .91; 12 months: 5.1% [0%; 10.2%] vs 6.0% [0%; 9.7%]; P = .71). CONCLUSIONS: Imaging findings after pulmonary embolism did not predict exercise limitation. Residual thrombus does not appear to explain long-term functional limitation after pulmonary embolism.

Myocardial Infarction With No Obstructive Coronary Artery Disease: Angiographic and Clinical Insights in Patients With Premature Presentation.

BACKGROUND: Premature myocardial infarction (MI) is an increasingly prevalent cause of morbidity and mortality worldwide. A subset of patients, predominantly young women, present with MI with no obstructive coronary artery disease (MINOCA), a nomenclature gaining recognition. However, few data exist on presentation and prognosis according to the severity of coronary artery disease (CAD). METHODS: We studied patients with premature (younger than 55 years of age) acute MI enrolled in a large cohort in 24 centres across Canada. Baseline clinical, psychosocial, and coronary anatomy characteristics as well as 12-month outcomes were compared between patients with MINOCA (< 50% stenosis) and patients with MI with obstructive CAD (≥ 50% stenosis; MICAD). RESULTS: From a cohort of 1210 patients with acute coronary syndrome, we examined 998 MI patients with available angiography core lab readings: 82 (8.2%) had a MINOCA and 916 (91.8%) had a MICAD. Forty percent of patients with MINOCA were women compared with one-third with MICAD. The prevalence of traditional risk factors and chest pain at presentation was lower in MINOCA patients, yet 37% had a ST-elevation MI and 10% presented with a cardiac arrest. No evident etiology was detected in > 70% of MINOCA, but 10% presented with either spontaneous coronary dissection or Takotsubo cardiomyopathy. Although combined major adverse cardiovascular events and all-cause readmission rate was lower in the MINOCA group (14% vs 25%; adjusted hazard ratio, 0.51; 95% confidence interval, 0.28-0.93), it was not negligible. CONCLUSIONS: Patients with MINOCA present with high-risk features despite the absence of obstructive CAD. A search for etiology and eventual treatment provides a rich avenue for improving prognosis in young women with premature MI.

Atrial Fibrillation Characteristics in Patients on Haemodialysis vs. Peritoneal Dialysis.

Atrial fibrillation (AF) is highly prevalent in dialysis patients, however whether its impact differs between patients on haemodialysis (HD) vs. peritoneal dialysis (PD) is unknown. We aimed to compare the association of AF and clinical outcomes in different dialysis modalities. We performed a population based retrospective cohort study, including adult patients who initiated dialysis between the years 2002 and 2015. Clinical, echocardiographic and laboratory data were reviewed and correlated with outcomes in HD vs. PD. During the study period, 1,130 patients began dialysis. Of the 997 patients without AF before dialysis initiation, 17% developed new-onset AF after the initiation of dialysis (17.3% of HD vs. 13.7% of PD patients, p = 0.27). Using multivariate analysis, only enlarged left atrium at dialysis initiation (hazard ratio (HR) 2.82, CI95% 2.00-3.99) and age (HR 1.04, CI95% 1.03-1.06) were significantly associated with AF. Dialysis modality was not a significant predictor of AF in either univariate or multivariate analysis. In conclusion, our study demonstrated that AF is common in dialysis patients irrespective of modality. In our cohort, the risk factors associated with AF were older age and enlarged left atrium. AF was associated with increased rates of heart failure and mortality, but not stroke.

Editor's Choice - Acute Cardiovascular Care Association Position Paper on Intensive Cardiovascular Care Units: An update on their definition, structure, organisation and function.

Acute cardiovascular care has progressed considerably since the last position paper was published 10 years ago. It is now a well-defined, complex field with demanding multidisciplinary teamworking. The Acute Cardiovascular Care Association has provided this update of the 2005 position paper on acute cardiovascular care organisation, using a multinational working group. The patient population has changed, and intensive cardiovascular care units now manage a large range of conditions from those simply requiring specialised monitoring, to critical cardiovascular diseases with associated multi-organ failure. To describe better intensive cardiovascular care units case mix, acuity of care has been divided into three levels, and then defining intensive cardiovascular care unit functional organisation. For each level of intensive cardiovascular care unit, this document presents the aims of the units, the recommended management structure, the optimal number of staff, the need for specially trained cardiologists and cardiovascular nurses, the desired equipment and architecture, and the interaction with other departments in the hospital and other intensive cardiovascular care units in the region/area. This update emphasises cardiologist training, referring to the recently updated Acute Cardiovascular Care Association core curriculum on acute cardiovascular care. The training of nurses in acute cardiovascular care is additionally addressed. Intensive cardiovascular care unit expertise is not limited to within the unit's geographical boundaries, extending to different specialties and subspecialties of cardiology and other specialties in order to optimally manage the wide scope of acute cardiovascular conditions in frequently highly complex patients. This position paper therefore addresses the need for the inclusion of acute cardiac care and intensive cardiovascular care units within a hospital network, linking university medical centres, large community hospitals, and smaller hospitals with more limited capabilities.

Contemporary Determinants of Delayed Benchmark Timelines in Acute Myocardial Infarction in Men and Women.

Treatment delays in patients with acute myocardial infarction (AMI) are related to increased morbidity and mortality. Hence, identifying determinants of delay may help reduce time to treatment. Importantly, limited data suggest that there may be sex-related disparities in benchmark timelines. Although guidelines advocate the use of the first medical contact (FMC) rather than hospital admission as the moment from which delays to treatment should be monitored, the latter is still often used for quality purposes. We aimed to identify factors associated with treatment delays, with an emphasis on sex-related disparities. We reviewed data on 3,658 patients with AMI from 2 contemporary, consecutive multicenter surveys. Measured delays were FMC-to-electrocardiogram >10 minutes in ST-elevation MI (STEMI) and non-STEMI, FMC-to-primary percutaneous coronary intervention >90 minutes in STEMI, and invasive angiography >72 hours after admission in non-STEMI patients. Timely electrocardiogram was performed in 48% of patients with STEMI and in 39.8% of non-STEMI patients without significant sex-related differences. Independent determinants of delay included atypical chest pain (CP) and presentation during daytime. In patients with STEMI, 37.5% had primary percutaneous coronary intervention in less than 90 minutes without significant sex-related disparities. Independent determinants of delay included atypical CP, night presentation, and diabetes. In non-STEMI patients, independent determinants of delayed invasive approach were female sex, age >75 years, atypical CP, and renal failure. In conclusion, significant treatment delays in patients with AMI are still frequent in contemporary practice, highlighting the need for improvement and guidelines implementation. Predictors of delay identified in our study may facilitate targeting of interventions to improve adherence to guidelines.

Quality of Life, Dyspnea, and Functional Exercise Capacity Following a First Episode of Pulmonary Embolism: Results of the ELOPE Cohort Study.

BACKGROUND: We aimed to evaluate health-related quality of life (QOL), dyspnea, and functional exercise capacity during the year following the diagnosis of a first episode of pulmonary embolism. METHODS: This was a prospective multicenter cohort study of 100 patients with acute pulmonary embolism recruited at 5 Canadian hospitals from 2010-2013. We measured the outcomes QOL (by Short-Form Health Survey-36 [SF-36] and Pulmonary Embolism Quality of Life [PEmb-QoL] measures), dyspnea (by the University of California San Diego Shortness of Breath Questionnaire [SOBQ]) and 6-minute walk distance at baseline and 1, 3, 6, and 12 months after acute pulmonary embolism. Computed tomography pulmonary angiography was performed at baseline, echocardiogram was performed within 10 days, and cardiopulmonary exercise testing was performed at 1 and 12 months. Predictors of change in QOL, dyspnea, and 6-minute walk distance were assessed by repeated-measures mixed-effects models analysis. RESULTS: Mean age was 50.0 years; 57% were male and 80% were treated as outpatients. Mean scores for all outcomes improved during 1-year follow-up: from baseline to 12 months, mean SF-36 physical component score improved by 8.8 points, SF-36 mental component score by 5.3 points, PEmb-QoL by -32.1 points, and SOBQ by -16.3 points, and 6-minute walk distance improved by 40 m. Independent predictors of reduced improvement over time were female sex, higher body mass index, and percent-predicted VO2 peak <80% on 1 month cardiopulmonary exercise test for all outcomes; prior lung disease and higher pulmonary artery systolic pressure on 10-day echocardiogram for the outcomes SF-36 physical component score and dyspnea score; and higher main pulmonary artery diameter on baseline computed tomography pulmonary angiography for the outcome PEmb-QoL score. CONCLUSIONS: On average, QOL, dyspnea, and walking distance improve during the year after pulmonary embolism. However, a number of clinical and physiological predictors of reduced improvement over time were identified, most notably female sex, higher body mass index, and exercise limitation on 1-month cardiopulmonary exercise test. Our results provide new information on patient-relevant prognosis after pulmonary embolism.

Functional and Exercise Limitations After a First Episode of Pulmonary Embolism: Results of the ELOPE Prospective Cohort Study.

BACKGROUND: We aimed to determine the frequency and predictors of exercise limitation after pulmonary embolism (PE) and to assess its association with health-related quality of life (HRQoL) and dyspnea. METHODS: One hundred patients with acute PE were recruited at five Canadian hospitals from 2010 to 2013. Cardiopulmonary exercise testing (CPET) was performed at 1 and 12 months. Quality of life (QoL), dyspnea, 6-min walk distance (6MWD), residual clot burden (perfusion scan, CT pulmonary angiography), cardiac function (echocardiography), and pulmonary function tests (PFTs) were measured during follow-up. The prespecified primary outcome was percent predicted peak oxygen uptake (Vo2 peak) < 80% at 1-year CPET. RESULTS: At 1 year, 40 of 86 patients (46.5%) had percent predicted Vo2 peak < 80% on CPET, which was associated with significantly worse generic health-related QoL (HRQoL), PE-specific HRQoL and dyspnea scores, and significantly reduced 6MWD at 1 year. Predictors of the primary outcome included male sex (relative risk [RR], 3.2; 95% CI, 1.3-8.1), age (RR, 0.98; 95% CI, 0.96-0.99 per 1-year age increase), BMI (RR 1.1; 95% CI, 1.01-1.2 per 1 kg/m2 BMI increase), and smoking history (RR, 1.8; 95% CI, 1.1-2.9), as well as percent predicted Vo2 peak < 80% on CPET at 1 month (RR, 3.8; 95% CI,1.9-7.2), and 6MWD at 1 month (RR, 0.82; 95% CI, 0.7-0.9 per 30-m increased walking distance). Baseline or residual clot burden was not associated with the primary outcome. Mean PFT and echocardiographic results (pulmonary artery pressure, right and left ventricular systolic function) at 1 year were similarly within normal limits in both patients with exercise limitations and those without such limitations. CONCLUSIONS: Almost half of patients with PE have exercise limitation at 1 year that adversely influences HRQoL, dyspnea, and walking distance. CPET or 6MWD testing at 1 month may help to identify patients with a higher risk of exercise limitation at 1 year after PE. Based on our results, we believe that the deconditioning that occurs after acute PE could underlie this exercise limitation, but we cannot exclude the fact that this may have been present before PE.

Sex Differences in Clinical Outcomes After Premature Acute Coronary Syndrome.

BACKGROUND: Over past decades, the incidence of acute coronary syndrome (ACS) has increased in young women, and greater mortality rates after discharge were observed among young women vs men. We revisited this issue with contemporary data from the Gender and Sex Determinants of Cardiovascular Disease: From Bench to Beyond Premature Acute Coronary Syndrome (GENESIS-PRAXY), a multicentre prospective cohort study. METHODS: One thousand two hundred thirteen patients were enrolled in GENESIS-PRAXY from 26 centres across Canada, the United States, and Switzerland between January 2009 and April 2013. We assessed major adverse cardiac events (MACE) and mortality over 12 months after ACS. The role of sex as a predictor of outcomes was determined with Cox proportional hazard regression analysis. RESULTS: We included 1163 patients with complete data. The occurrence of MACE was 9% and 8% in women and men, respectively (P = 0.75), and 1% of women and men died during follow-up. In adjusted models, there was no sex difference in the risk of MACE or mortality. The proportion of patients with all-cause rehospitalization was higher in women (13%) compared with men (9%; P = 0.006), but cardiac rehospitalization rates were similar in both sexes regardless of ACS type. Among first rehospitalizations, the majority was classified as cardiac related (69%), with chest pain or angina (28%) and myocardial infarction (19%) reported as the most common reasons for first rehospitalization. CONCLUSIONS: Women were more likely than men to be rehospitalized for all causes but not for a cardiac cause. In contrast to earlier studies, men and women had similar mortality and MACE outcomes at 1 year.

Combination Therapy for Pulmonary Arterial Hypertension: A Systematic Review and Meta-analysis.

BACKGROUND: Combination therapy (CT) for patients with pulmonary arterial hypertension (PAH) has been recommended for many years, despite weak evidence of efficacy over monotherapy (MT). A previous meta-analysis comparing CT vs MT with pulmonary vasodilators failed to demonstrate a clear reduction in clinical worsening events. METHODS: We searched for relevant articles in PubMed, EMBASE, the Cochrane Database, and clinicaltrials.gov; we also manually searched review articles and conference abstracts from 1980-December 2015. Target articles were double-blinded studies of 2 or more pulmonary vasodilators given in combination vs monotherapy for treatment of patients with PAH. The principal outcome of interest was "combined clinical worsening" (CCW) events (including but not limited to death or hospitalization). Data on physiological outcomes were also explored. Meta-analysis was performed using the DerSimonian and Laird random-effects model. RESULTS: We extracted data from 18 randomized controlled trials (RCTs) (N = 4162). CT was associated with a significant 38% reduction of risk of CCW (15 RCTs: n = 3906; risk ratio [RR], 0.62; 95% confidence interval [CI], 0.50-0.77). This reduction in risk was driven by a reduction in nonfatal end points (12 RCTs: n = 2611; RR, 0.56; 95% CI, 0.40-0.78) and not by a reduction of mortality (12 RCTs: n = 2717; RR, 0.79; 95% CI, 0.53-1.17). CT was also associated with improvement in 6-minute walking distance (10 RCTs: n = 1553; weighted mean difference [WMD], +23.0 m; 95% CI, 15.9-30.1), improved functional class (9 RCTs: n = 1737; RR, 1.26; 95% CI, 1.05-1.51), and beneficial effects on pulmonary hemodynamics such as cardiac index (WMD, +0.35 L/min/m; 95% CI, 0.14-0.56). CONCLUSIONS: In this highly comprehensive meta-analysis, CT reduces the risk of CCW events in patients with PAH and brings physiological improvement.

Angiographic Characteristics of Catheter-Induced Spasm of the Left Main Coronary Artery.

Spasm of the left main coronary artery (LM) is considered to be rare. We investigated the angiographic characteristics of the LM in patients with combined LM and disease involving additional vessels, who underwent coronary artery bypass grafting (CABG) and underwent repeat coronary angiography within 5 years of the CABG, to examine the apparent frequency of spasm of the LM on initial angiography and its possible predictors. A retrospective analysis was performed of patients who underwent coronary angiography in our institute, who were found to have significant LM stenosis and disease involving additional vessels, underwent CABG and repeat coronary angiography within 5 years of the CABG. Data on angiographic characteristics of the LM on the initial angiogram were investigated. Of 84 patients, 17 (20%) were found to have a normal LM on repeat angiography (group A), and 67 (80%) demonstrated significant stenosis (group B). The degree of LM stenosis was milder in the initial angiogram in group A than in group B (64 ± 15% vs 72 ± 14%, p = 0.047). Most patients in group A demonstrated tubular LM stenosis at initial catheterization in comparison to group B (71% vs 18%). Using multivariate analysis, the only predictor for a normal LM at repeat catheterization was found to be tubular stenosis at initial catheterization (odds ratio 123, 95% confidence interval 4.0 to 3696). In conclusion, LM coronary spasm is a common finding, particularly in those with the appearance of tubular stenosis, and it should be excluded even in patients with additional coronary disease in certain instances to prevent unnecessary CABG.

In-hospital switching from clopidogrel to prasugrel following thrombolysis for ST-elevation myocardial infarction: a 3-year single center experience.

BACKGROUND: Prasugrel has proved its superiority over clopidogrel for reducing ischemic events among patients with ST elevation myocardial infarction (STEMI) undergoing urgent percutaneous coronary intervention (PCI). Data on switching of antiplatelet therapy in acute coronary syndrome patients in clinical practice are very limited. Importantly, the safety of in-hospital switching from clopidogrel to prasugrel following thrombolysis has not been addressed. METHODS: We reviewed consecutive STEMI patients from February 2011 to April 2014 who were transferred to a tertiary center after receiving thrombolysis and a loading dose of clopidogrel in a non-PCI-capable center. If not contraindicated, these patients were reloaded and treated with prasugrel. A control group, three times larger, was selected from patients who underwent primary PCI and were initially treated with prasugrel. In-hospital outcomes were examined. RESULTS: Cases (n=45, 13% female, mean age 56 years) and controls (n=135, 11% female, mean age 54 years) did not differ significantly with respect to MI location, left ventricular systolic function, and extent of coronary artery disease. Mean time from thrombolysis to prasugrel loading was 32±19 hours. No significant differences were found between cases and controls in TIMI major or minor bleeding (0% vs. 3%), overall mortality (0% vs. 1.5%), and hospitalization length (4.8 vs. 5.5 days). CONCLUSIONS: In-hospital reloading and subsequent maintenance therapy with prasugrel in patients who received thrombolysis and a loading dose of clopidogrel appears to be as safe as in STEMI patients managed by primary PCI; however, larger studies are needed to verify these results.

Breast cancer-related lymphedema: a randomized controlled pilot and feasibility study.

OBJECTIVE: Chronic lymphedema occurs frequently in breast cancer patients and is associated with significant morbidity and reduced quality-of-life. In this pilot study, the authors (1) addressed whether conducting a larger randomized controlled trial of aqua lymphatic therapy (ALT) would be feasible and (2) estimated the extent to which ALT combined with home-based exercise compared with home-based exercise alone would reduce arm disability in patients with breast cancer-related lymphedema. DESIGN: Twenty-five women with breast cancer-related lymphedema were randomized to either ALT in addition to a home land-based exercise program (ALT group; n = 13) or to a home land-based exercise program alone (control group; n = 12). The participants were evaluated before and after a 12-wk intervention period composed of weekly pool exercise sessions. Main outcome measures were arm volume, arm disability, pain, and quality-of-life. RESULTS: At follow-up, there was no statistical difference between the control and ALT groups in any of the outcomes, except for present pain intensity. At the end of the study period, there was no change in the lymphedematous limb volume in either group. Grip strength was improved in both groups. Only the ALT group showed a statistically significant difference with a reduction in pain intensity score and arm disability. Furthermore, quality-of-life significantly improved only in the ALT group. CONCLUSIONS: Conducting a larger randomized controlled trial would be feasible. In comparison with the beginning of the intervention, the participants in the ALT group showed significant beneficial changes after 12 wks of treatment, whereas the control group did not improve. ALT did not make the lymphedema volume worse and therefore may serve as a safe alternative to land-based treatments of breast cancer-related lymphedema.

Sex-related differences in access to care among patients with premature acute coronary syndrome.

BACKGROUND: Access to care may be implicated in disparities between men and women in death after acute coronary syndrome, especially among younger adults. We aimed to assess sex-related differences in access to care among patients with premature acute coronary syndrome and to identify clinical and gender-related determinants of access to care. METHODS: We studied 1123 patients (18-55 yr) admitted to hospital for acute coronary syndrome and enrolled in the GENESIS-PRAXY cohort study. Outcome measures were door-to-electrocardiography, door-to-needle and door-to-balloon times, as well as proportions of patients undergoing cardiac catheterization, reperfusion or nonprimary percutaneous coronary intervention. We performed univariable and multivariable logistic regression analyses to identify clinical and gender-related determinants of timely procedures and use of invasive procedures. RESULTS: Women were less likely than men to receive care within benchmark times for electrocardiography (≤ 10 min: 29% v. 38%, p = 0.02) or fibrinolysis (≤ 30 min: 32% v. 57%, p = 0.01). Women with ST-segment elevation myocardial infarction (MI) were less likely than men to undergo reperfusion therapy (primary percutaneous coronary intervention or fibrinolysis) (83% v. 91%, p = 0.01), and women with non-ST-segment elevation MI or unstable angina were less likely to undergo nonprimary percutaneous coronary intervention (48% v. 66%, p < 0.001). Clinical determinants of poorer access to care included anxiety, increased number of risk factors and absence of chest pain. Gender-related determinants included feminine traits of personality and responsibility for housework. INTERPRETATION: Among younger adults with acute coronary syndrome, women and men had different access to care. Moreover, fewer than half of men and women with ST-segment elevation MI received timely primary coronary intervention. Our results also highlight that men and women with no chest pain and those with anxiety, several traditional risk factors and feminine personality traits were at particularly increased risk of poorer access to care.
