Chronic stress and early recurrence of takotsubo cardiomyopathy: A clinical case

2014

Takotsubo cardiomyopathy (TC) is characterized by transient systolic dysfunction of the apical and middle segments of the left ventricle, accompanied by electrocardiographic abnormalities and mild elevation of cardiac biomarker levels in the absence of obstructive coronary artery disease. The following case is of a woman suffering from chronic emotional stress with a very early recurrence. An acute trigger event was not detectable in both cases. It is possible to suppose that, in predisposed subjects, chronic stress by increasing sympathetic activity may be considered not only a trigger for TC, but also a negative prognostic factor for early recurrence.

OP21.08: Genetic predisposition of pre-eclampsia and changed flow in uterine artery basin

Erfassung hämodynamischer Parameter bei Patienten mit chronischer thromboembolischer pulmonaler Hypertonie mittels MRT vor und nach Thrombendarteriek…

2003

Purpose: To evaluate the potential of MRI to grade cardiac impairment and pulmonary hypertension in patients with chronic thromboembolic pulmonary hypertension (CTEPH) in comparison with invasive pressure measurements before and after surgery. Materials and Methods: We examined 35 patients with CTEPH before and after pulmonary thromboendarterectomy (PTE). For assessment of hemodynamics, velocity-encoded segmented GE-sequences (pulmonary arteries and ascending aorta) and segmented cine GE-sequences along the short axis of the heart were performed. The analysis comprised calculation of ejection fractions, peak velocities, mean pulmonary arterial flow and vessel diameter. 10 volunteers served …

Interleukin-18 Is a Strong Predictor of Cardiovascular Death in Stable and Unstable Angina

2002

Background — Interleukin (IL)-18 plays a central role in orchestrating the cytokine cascade and accelerates atherosclerosis and plaque vulnerability in animal models. However, epidemiological data evaluating the role of IL-18 levels in atherosclerosis are lacking. Methods and Results — In a prospective study of 1229 patients with documented coronary artery disease, we measured baseline serum concentrations of IL-18 and other markers of inflammation. During the follow-up period (median, 3.9 years), 95 patients died of cardiovascular causes. Median serum concentrations of IL-18 were significantly higher among patients who had a fatal cardiovascular event than among those who did not (68.4 ve…

0058 : Low circulating levels of Growth Differentiation Factor 15 (GDF-15) before coronary artery bypass surgery may predict post-operative atrial fi…

2015

BackgroundPost-operative atrial fibrillation (POAF) following cardiac surgery has a high prevalence and is associated with considerable morbidity.AimsTo assess the role of GDF-15, a member of the TGFβsuperfamily, as a potential new predictor of POAF after off-pump (OFP) and on-pump (ONP) coronary artery bypass graft (CABG) surgery.MethodsThis observational study recruited the first 50 patients planned for OFP surgery and the first 50 patients planned for ONP surgery. Patients referred for CABG with the following exclusion criteria: age 80 years, previous atrial fibrillation/flutter, previous treatment with Amiodarone, previous cardiac surgery, emergency surgery. Included patients were equip…

Cocaine-induced coronary thrombosis and acute myocardial infarction

2004

A 26-year-old man was admitted to our hemodynamic laboratory because of an anterior AMI and post myocardial infarction angina. He is an active smoker (10 cigarettes/day) and consumes inhaled cocaine during weekends (the last consumption of cocaine was 1 week ago). No others risk factors were recorded. Initial electrocardiogram shows sinus rhythm and anterior QS complex (V1–V3) with anterolateral ST segment elevation (V1–V5, D1 and aVL). Creatine-kinase isoenzyme MB and Troponin I were elevated at arrival. Upon admission, the patient was normotensive but with signs of pulmonary congestion. Ventriculography showed anterolateral and apical hypokinesia with an ejection fraction of 21%. Coronari…

Small, dense low-density-lipoproteins and the metabolic syndrome.

2006

Small, dense low-density-lipoproteins (LDL) are associated with increased risk for cardiovascular diseases and diabetes mellitus and a reduction in LDL size has been reported in patients with coronary and non-coronary forms of atherosclerosis. LDL size has been accepted as an important predictor of cardiovascular events and progression of coronary artery disease as well as an emerging cardiovascular risk factor by the National Cholesterol Education Program Adult Treatment Panel III. Small, dense LDL, with elevated triglyceride levels and low HDL-cholesterol concentrations, constitute the 'atherogenic lipoprotein phenotype (ALP)', a form of atherogenic dyslipidemia that is a feature of type …

The Role of Small, Dense Low-Density-Lipoproteins in Non-Coronary Forms of Atherosclerosis

2008

Small, dense low density lipoproteins (LDL) are associated with increased risk for cardiovascular disease and seem to be an important predictor of cardiovascular events and progression of coronary artery disease. In addition, the predominance of small dense LDL has been accepted as an emerging cardiovascular risk factor by the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III). Less data is available on the role of LDL size in the prevention of vascular diseases, including peripheral arterial disease, carotid artery disease and abdominal aortic aneurysm. The NCEP-ATP III stated that clinical non-coronary atherosclerosis carries a risk for coronary heart disease …

Trans-limb embolization for treatment of Type 2 endoleak post EVAR: Case report

2021

Introduction Type 2 endoleaks (T2EL) occur after 10%–25% of endovascular abdominal aortic aneurysm repairs and increase the risk factor of endograft repair failure and rupture. Herein we report a case of endovascular treatment of T2EL where we performed a trans-limb embolization. Presentation of case A 63-years-old male previously treated for AAA with endovascular aortic aneurysms repair (EVAR), showed an angio-CT scan followup with a type 2 endoleak fed from inferior mesenteric artery (AMI) with growth of AAA greater of 1 cm than preoperative CT-scan and increase of chronic lumbar pain. Due to high risk of rupture was performed a trans-limb embolization with complete sealing. The 6 months …

Vascular Decompression of Trigeminal and Facial Nerves in the Posterior Fossa under Endoscope-Assisted Keyhole Conditions

2008

Objective: The aim of this study was to determine the use and safety of the endoscope as an adjunct during trigeminal and facial nerve decompression procedures performed under keyhole conditions in the posterior fossa. Method: We performed 67 surgeries in 65 patients with symptomatic trigeminal and facial nerve compression syndromes. The diagnosis was made mainly on the basis of clinical history, examination, and magnetic resonance imaging scans. Surgery was performed in all cases under endoscope-assisted keyhole conditions. The follow-up was 1 week postoperatively, 6 months, and then yearly up to 7 years. All 34 patients with trigeminal neuralgia received preoperative medication treatment …
