Imaging funzionale per diffusione (DWI) e ischemia cerebrale in fase acuta: Potenzialità diagnostiche e confronto con metodiche convenzionali
1997
Stroke is the third leading cause of death and is a major cause of long-term disability. Neuroprotective treatment within a 4-hour «therapeutic window» has proved highly efficacious in reducing morbility and mortality in animal model. It is with this background that the need for emergent diagnosis and therapy of acute stroke in strongly suggested. Computed tomography (CT) shows the parenchymal changes of acute stroke too late to be helpful, and its role has been primarily to evaluate the possibility of intracerebral or subarachnoid hemorrhage. While conventional magnetic resonance (MR) imaging can demonstrate parenchymal abnormalities 4–6 hours after ischemia, newer techniques such as diff…
EpCAM and microvascular obstruction in patients with STEMI: a cardiac magnetic resonance study
2020
Abstract Introduction and objectives Microvascular obstruction (MVO) is negatively associated with cardiac structure and worse prognosis after ST-segment elevation myocardial infarction (STEMI). Epithelial cell adhesion molecule (EpCAM), involved in epithelium adhesion, is an understudied area in the MVO setting. We aimed to determine whether EpCAM is associated with the appearance of cardiac magnetic resonance (CMR)-derived MVO and long-term systolic function in reperfused STEMI. Methods We prospectively included 106 patients with a first STEMI treated with percutaneous coronary intervention, quantifying serum levels of EpCAM 24 hours postreperfusion. All patients underwent CMR imaging 1 w…

Impact of prehospital delay on mortality in patients with acute myocardial infarction treated with primary angioplasty and intravenous thrombolysis.
2001
Abstract Background In patients with acute myocardial infarction treated with thrombolysis, longer times to treatment are associated with increasingly worse clinical outcome. This relation may be different for treatment with primary angioplasty. Methods We analyzed the pooled data of the German acute myocardial infarction registries Maximal Individual Therapy in Acute Myocardial Infarction (MITRA) and Myocardial Infarction Registry (MIR) to determine the influence of prehospital delays on hospital mortality rates. Primary angioplasty was performed in 1063 patients and thrombolysis in 7552 patients. Results In patients treated with thrombolysis, in-hospital time to treatment was constantly 3…
Prevalence and characteristics of coronary artery disease in a population with suspected ischaemic heart disease using CT coronary angiography: corre…
2008
Purpose. This study was undertaken to describe the correlation between the distribution of coronary artery disease (CAD) in a symptomatic population with suspected ischaemic heart disease, cardiovascular risk factors (RF) and clinical presentation. Materials and methods. We studied 163 patients (mean age 65.5 years; 101 men and 62 women) referred for multidetector computed tomography coronary angiography (MDCT-CA) to rule out CAD. The patients had no prior history of revascularisation or myocardial infarction. We analysed how the characteristics of CAD (severity and type of plaque) can change with the increase in RF and how they are related to different clinical presentations. Results. Pati…
Environmental stressors and cardiovascular risk: Impact of environmental noise exposure on vascular oxidative stress and damage
2018
Epidemiological studies have demonstrated that traffic noise exposure is associated with cardiovascular diseases such as arterial hypertension, myocardial infarction and stroke. Persistent chronic noise exposure increases the risk of cardiovascular and metabolic diseases such as arterial hypertension, coronary artery disease, diabetes and stroke. Large epidemiological studies (reviewed in Munzel et al. Eur. Heart J. 2017, 38 (8):550–556) point towards a link between the incidence of ischemic heart diseases and exposure to noise, supporting its role as an independent cardiovascular risk factor. Recently, the underlying molecular mechanisms leading to noise-dependent adverse effects on the va…
Serum brain-derived neurotrophic factor and platelet activation evaluated by soluble P-selectin and soluble CD-40-ligand in patients with acute myoca…
2009
Little is known about the role of neurotrophins (NT) under adult vascular homeostasis in normal and pathological conditions. The NT family, including nerve growth factor and brain-derived neurotrophic factor (BDNF) are expressed in atherosclerotic vessels. Previous studies demonstrated that plasma BDNF levels were increased in the coronary circulation in patients with unstable angina. However, the role of BDNF during the onset and evolution of unstable angina remains to be elucidated. The objective of this study was to evaluate the relationship between BDNF, functional parameters and biological markers associated with inflammatory processes and platelet activation. BDNF serum levels were as…
Diabetes Mellitus and Its Impact on Patient-Profile and In-Hospital Outcomes in Peripheral Artery Disease
2021
Background: In patients with peripheral artery disease (PAD), the impact of diabetes mellitus (DM) on patient-profile and adverse in-hospital events is not well investigated. Methods: The German nationwide inpatient sample 2005–2019 was used for this analysis. Hospitalized PAD patients were stratified for DM and the influence of DM on patient-profile and adverse in-hospital events was investigated. Results: Our study comprised 2,654,871 hospitalizations (54.3% aged ≥70 years, 36.7% females) of patients with PAD in Germany 2005–2019. Among these, 864,691 (32.6%) patients had DM and 76,716 (2.9%) died during hospitalization. Diabetic PAD patients revealed an aggravated cardiovascular profile …
Metformin and contrast-induced acte kidney injury in diabetic patients treated with primary percutaneous coronary intervention for ST segment elevati…
2016
IF 4.638; International audience; AIM : To analyze the association between chronic metformin treatment and the development of contrast-induced acute kidney injury (CI-AKI) after primary percutaneous coronary intervention (PCI) for ST segment elevation myocardial infarction (STEMI).METHODS: Patients with type 2 diabetes mellitus (T2DM) treated with PCI 27μmol/l (0.3mg/dl) or >50% over baseline after PCI. Since PCI was urgent, metformin could not be withheld prior to PCI but was usually stopped after PCI.RESULTS:Among the 372 patients included, 147 (40%) were using metformin, which had older diabetes, but had risk factors similar to patients without metformin. Baseline eGFR was better in pati…
Cardio‐Renal Biomarker Soluble Urokinase‐Type Plasminogen Activator Receptor Is Associated With Cardiovascular Death and Myocardial Infarction in Pat…
2020
Background Risk stratification among patients with coronary artery disease ( CAD ) is of considerable interest due to the potential to guide secondary preventive therapies. Thus, we evaluated the predictive value of soluble urokinase‐type plasminogen activator receptor (su PAR ) levels for cardiovascular mortality and nonfatal myocardial infarction in patients with CAD . Methods and Results Plasma levels of su PAR were measured in a cohort of 1703 patients with documented CAD as evidenced by coronary angiography—including 626 patients with acute coronary syndrome and 1077 patients with stable angina pectoris. Cardiovascular death and/or nonfatal myocardial infarction were defined as main o…
