A 77-year-old woman with atrial fibrillation (AF) treated with warfarin had a cortical left middle cerebral artery (MCA) stroke (October 2009, international normalized ratio [INR], 1.6) and a cortical left frontal stroke (October 2011, INR, 1.9). Anticoagulation was adjusted. In October 2011, she had a right frontal stroke (INR, 2.3). Acetylsalicylic acid(More)
BACKGROUND Serum soluble CD40 Ligand (sCD40L) levels, which exhibit prothrombotic and proinflammatory properties, have not been studied in patients with traumatic brain injury (TBI). Thus, the objective of this study was to determine whether serum sCD40L levels are associated with severity and mortality in patients with severe TBI. METHODS This was a(More)
A new case of postnephrectomy arteriovenous fistula is reported. This is an uncommon acquired complication of a common surgical procedure. Clinical features, diagnostic procedures, surgical treatment and results are analysed and discussed. In this case, a direct communication between the right renal artery and the inferior vena cava was found.
AIM To study whether the concentrations of particulate matter in ambient air are associated with hospital admission due to heart failure in patients with heart failure with preserved ejection fraction and reduced ejection fraction. METHODS We studied 353 consecutive patients admitted into a tertiary care hospital with a diagnosis of heart failure.(More)
Cytokeratin (CK)-18 is the major intermediate filament protein in the liver and during hepatocyte apoptosis is cleaved by the action of caspases; the resulting fragments are released into the blood as caspase-cleaved cytokeratin (CCCK)-18. Higher circulating levels of CCCK-18 have been found in patients with hepatocellular carcinoma (HCC) than in healthy(More)
In patients with previous coronary artery bypass graft surgery, it is unknown whether better results may be obtained with percutaneous interventions of grafts versus native arteries. The clinical outcomes in 84 patients undergoing percutaneous interventions of either grafts (n = 31) or native arteries (n = 53) were compared. Procedural success rate was(More)
INTRODUCTION AND OBJECTIVES Currently air pollution is considered as an emerging risk factor for cardiovascular disease. Our objective was to study the concentrations of particulate matter in ambient air and analyze their relationship with cardiovascular risk factors in patients admitted to a cardiology department of a tertiary hospital with the diagnosis(More)
BACKGROUND An increasing number of patients undergoing percutaneous interventions (PI) have experienced previous coronary artery bypass graft surgery (CABG). However, the impact of PI on outcomes in such patients is currently unclear. We evaluated the immediate and 1-year clinical outcomes of post-CABG patients who underwent PI in a tertiary center. (More)
