Prognostic Value of Charlson Comorbidity Index at 30 Days and 1 Year After Acute Myocardial Infarction

2004

Introduction and objectives. The Charlson comorbidity index (CCI), an indicator of comorbidity, has been used as an adjusting variable in multivariate models. Because of its prognostic value per se for cardiovascular complications after acute myocardial infarction (AMI), we sought to determine the predictive value of the CCI for allcause mortality and recurrent AMI 30 days and 1 year after the index event. Patients and method. We analyzed 1035 consecutive patients admitted with the diagnosis of AMI (ST elevation=508 and non-ST elevation=527). The composite endpoint was determined after 30 days (13.9%) and 1 year (26.3%) of follow-up. The CCI was calculated on admission, and other variables …

Combining Body Mass Index With Measures of Central Obesity in the Assessment of Mortality in Subjects With Coronary Disease

2013

Objectives This study sought to assess the mortality risk of patients with coronary artery disease (CAD) based on a combination of body mass index (BMI) and measures of central obesity. Background In CAD patients, mortality has been reported to vary inversely with BMI (“obesity paradox”). In contrast, central obesity is directly associated with mortality. Because of this bi-directional relationship, we hypothesized that CAD patients with normal BMI but with central obesity would have worse survival compared with subjects with other combinations of BMI and central adiposity. Methods We included 15,547 participants with CAD who took part in 5 studies from 3 continents. Multivariate stratified…

2019

Background It remains unclear whether the distal location of deep vein thrombosis (DVT) is independently associated with a lower risk of recurrence in all patients, or represents a marker of the presence and severity of provoking factors for venous thromboembolism (VTE). Methods We investigated the impact of distal (vs. proximal) DVT location on the risk of developing symptomatic, objectively confirmed recurrent VTE in 831 patients with a first acute symptomatic DVT not associated with pulmonary embolism (PE), who were stratified by the presence of transient or persistent risk factors at baseline. The primary outcome was symptomatic, objectively diagnosed recurrent VTE, including proximal …

Comparison of 2 Doses of Intravenous (IV) Temsirolimus (Temsr) in Patients with Relapsed/Refractory Mantle Cell Lymphoma (MCL)

2016

Abstract Introduction: Temsr (Torisel®) administered at 175 mg IV once weekly for first 3 weeks, followed by 75mg IV once weekly (Temsr 175/75 mg) is approved in the European Union for the treatment of adult patients with relapsed and/or refractory MCL based on an overall positive benefit-risk relationship demonstrated for this treatment regimen in the pivotal phase III study (Hess et al. J Clin Oncol. 2009;27:3822-9). This ongoing phase 4, multicenter, randomized, open-label study was conducted to explore whether similar efficacy can be achieved for the treatment of patients with relapsed/refractory MCL with a Temsr regimen that is expected to yield fewer side effects than the Temsr 175/75…

Prognostic factors for remission of and survival in acquired hemophilia A (AHA): results from the GTH-AH 01/2010 study

2015

Acquired hemophilia A (AHA) is caused by autoantibodies against factor VIII (FVIII). Immunosuppressive treatment (IST) results in remission of disease in 60% to 80% of patients over a period of days to months. IST is associated with frequent adverse events, including infections as a leading cause of death. Predictors of time to remission could help guide IST intensity but have not been established. We analyzed prognostic factors in 102 prospectively enrolled patients treated with a uniform IST protocol. Partial remission (PR; defined as no active bleeding, FVIII restored >50 IU/dL, hemostatic treatment stopped >24 hours) was achieved by 83% of patients after a median of 31 days (range 7-362…

Long-Term Clinical Outcomes After Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting for Ostial/Midshaft Lesions in Unprotecte…

2014

Objectives The aim of this study was to report the long-term clinical outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) for ostial/midshaft lesions in an unprotected left main coronary artery (ULMCA). Background Data regarding outcomes in these patients are limited. Methods Of a total of 2,775 patients enrolled in the DELTA multinational registry, 856 patients with isolated ostial/midshaft lesions in an ULMCA treated by PCI with DES (n = 482) or CABG (n = 374) were analyzed. Results At a median follow-up period of 1,293 days, there were no significant differences in the propensity score-adjusted analyses for …

Effect of storage time and donor sex of transfused red blood cells on 1-year survival in patients undergoing cardiac surgery: an observational study

2016

BACKGROUND Red blood cell (RBC) storage lesions and RBCs from females transfused into male recipients may have adverse effects on transfusion recipients' survival. We hypothesized that the effect of donor sex and the effect of age of blood on mortality would be most apparent in cardiac surgery patients. STUDY DESIGN AND METHODS Using data from French Blood Services and two university hospitals, we conducted a retrospective cohort study on cardiac surgery patients whose first transfusion occurred between 2007 and 2011. The age of blood and donor sex effects on 1-year survival were studied using Cox regression modeling, with time-dependent stratification on the number of RBCs and adjustments …

Serum Heat Shock Protein 60 in Acute Heart Failure: A New Biomarker?

2012

Heat shock protein 60 (HSP60) is a mitochondrial protein constitutively expressed in the majority of cells, and its expression is up-regulated by a variety of stressors. In heart failure, HSP60 is released from cardiomyocytes. The authors speculate that increased serum HSP60 (sHSP60) may be related to the severity of heart failure. This investigation sought to assess the association between sHSP60 and the composite end point of death ⁄ readmission in patients with acute heart failure (AHF). A total of 132 consecutive patients were admitted for AHF. The independent association between sHSP60 and the end point was assessed with Cox regression. During a median follow-up of 7 months (interquart…

Drug-Eluting Stent for Left Main Coronary Artery Disease

2012

Objectives The aim of this study was to compare, in a large all-comers registry, major adverse cardiac and cerebrovascular events (MACCE) after percutaneous coronary intervention (PCI) with first-generation drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) in unprotected left main coronary artery (ULMCA) stenosis. Background Percutaneous coronary intervention with DES implantation in ULMCA has been shown to be a feasible and safe approach at midterm clinical follow-up. Methods All consecutive patients with ULMCA stenosis treated by PCI with DES versus CABG were analyzed in this multinational registry. A propensity score analysis was performed to adjust for baseline dif…
