OBJECTIVES The purpose of this study was to develop an adenosine-independent, pressure-derived index of coronary stenosis severity. BACKGROUND Assessment of stenosis severity with fractional flow reserve (FFR) requires that coronary resistance is stable and minimized. This is usually achieved by administration of pharmacological agents such as adenosine.(More)
BACKGROUND There is growing evidence supporting the role of inflammation in aneurysmal subarachnoid hemorrhage (aSAH) pathophysiology and it is of great interest to elucidate which immune mechanisms are involved. METHODS 12 aSAH patients and 28 healthy controls were enrolled prospectively. We assessed leukocytes subpopulations and their activation status(More)
BACKGROUND In chronic ischemic heart disease, focal stenosis, diffuse atherosclerotic narrowings, and microcirculatory dysfunction (MCD) contribute to limit myocardial flow. The prevalence of these ischemic heart disease levels in fractional flow reserve (FFR) interrogated vessels remains largely unknown. METHODS AND RESULTS Using intracoronary(More)
INTRODUCTION Patient Generated Subjective Global Assessment (PG-SGA) is a validated tool for nutrition evaluation in patients with cancer. AIM The aim of our study was to estimate the prevalence of malnutrition in head and neck cancer patients at diagnosis and evaluate the independent prognostic factors for malnutrition from PG-SGA. MATERIAL AND METHODS(More)
The frequency and profile of lymphocyte subsets within the culprit coronary artery were investigated in 33 patients with myocardial infarction and compared to their systemic circulating counterparts. T cell subsets including CD4(+)CD28null, activated and regulatory T-cells, TH1/TH2/TH17 phenotypes, NK and B-cells were studied in intracoronary (IC) and(More)
A best evidence topic was written according to a structured protocol. Lack of evidence exists regarding the optimal timing for coronary artery bypass graft (CABG) surgery after non-ST myocardial infarction (NSTEMI). While some authors address the importance of the timing of surgery alone, others take into account the extent of myocardial damage. The(More)
The need to improve stent deliverability has led to the development of thinner and more flexible stents. However, there is concern about decreased longitudinal strength. The number of longitudinal stent deformation reports has dramatically increased. We report a case of stent longitudinal deformation after thromboaspiration through a new generation platinum(More)
Villous colorectal adenomas are common tumors that normally provoke scarce symptomatology. We report a 59 year-old female that was admitted with severe dehydration due to severe diarrhea lasting 10 days and vomiting in the last 48 hours. On rectal palpation a large tumor located 5 cm above the anus was palpated. Colonoscopy confirmed the presence of a(More)
Coronary artery aneurysm is defined as a coronary dilation that exceeds the diameter of adjacent segments or the diameter of the patient's largest normal coronary vessel by 1.5×. It is an uncommon disease that has been diagnosed with increasing frequency since the widespread appearance of coronary angiography. The published incidence varies from 1.5% to 5%,(More)
