Retinal vessel analysis and heart rate variability

2014

Heart rate variability (HRV) is used to index the vegetative nervous system and is linked with cardiovascular and nervous diseases [1]. Funduscopic assessment of the retinal vasculature can be utilized to evaluate the health status of microcirculation and to assess the predisposition of major vascular diseases [2]. The purpose of this study was, for the first time, to examine the influence of HRV on microcirculation as an early marker of cardiovascular alteration. The study population was comprised of apparently healthy employees of a high-tech company in Germany. The participants spanned the entire age of the work force (18–65 years) and all levels of socioeconomic status. A total of 292 s…

Decision making in a presumptive case of STEMI-like myocarditis

2015

In youngmales, differential diagnosis during chest pain is not always easy. When ECG findings suggest a cardiac origin of such symptoms, myo-pericarditis is usually themost likely hypothesis, beingmore common than Acute Coronary Syndromes (ACS) in the first decades of life [1]. In the presence of ST segment elevation, Troponin release and ventricular wall motion abnormalities, the diagnosis can be challenging, though. In the young a lowcoronary risk profile and atypical symptoms seldom support a working diagnosis of Coronary Heart Disease (CHD), and, therefore, urgent coronary angiography is not recommended routinely, although cases of early ACS are not so rare. In October 2014 a 26-year-ol…

Assessment of the distal anastomosis of coronary artery bypass grafts with a 2D T2-weighted turbo spin echo sequence and correlation to conventional …

2005

Abstract Objective The aim of the study was to evaluate the patensies of the distal anastomoses of coronary artery bypass grafts and to detect graft stenoses and occlusions with a magnetic resonance (MR) spin echo sequence. Patients and methods One hundred and eighty-five patients with 481 distal anastomoses were examined with a 1.5 T MR scanner and coronary angiography. A 2-dimensional T2-weigthed breath-hold half-Fourier acquisition single-shot turbo spin echo sequence (Haste) was performed. All images were evaluated independently by a radiologist and cardiologist and compared to the conventional coronary angiography. The observers were blinded to the coronary angiography findings, but in…

Outcomes after acute myocardial infarction in HIV-infected patients: analysis of data from a French nationwide hospital medical information database.

2013

Background— We aimed to assess in-hospital case fatality and 1-year prognosis in HIV-infected patients with acute myocardial infarction. Methods and Results— From the PMSI (Program de Medicalisation des Systèmes d’informatique) database, data from 277 303 consecutive acute myocardial infarction patients hospitalized from January 1, 2005, to December 31, 2009, were analyzed. Surviving patients were followed up for 1 year after discharge. HIV-infected patients were compared with uninfected patients. Among the cohort, HIV-infected patients (n=608) accounted for 0.22%. All-cause hospital and 1-year mortality rates were lower in the HIV-infected group than in uninfected patients (3.1% versus 8.…

Early outcome after implantation of Absorb bioresorbable drug-eluting scaffolds in patients with acute coronary syndromes

2013

The safety of BVS implantation in patients with a high risk for early thrombotic complications has not been studied. We report on the outcomes of patients with acute coronary syndromes (ACS) treated with bioresorbable, everolimus-eluting, vascular scaffolds (BVS).150 consecutive patients with ACS (194 lesions) treated with BVS between May 2012 and July 2013 were compared with a control group composed of 103 consecutive patients (129 lesions) who underwent everolimus drug-eluting stent (DES) implantation in the same time period. The incidence of major adverse cardiac events (MACE: death, non-fatal myocardial infarction, or reintervention) before discharge, at one month and six months was eva…

Evaluation of regional haemodynamics and alterations of vascular wall of the lower limbs in hypertensive subjects

1995

This study was designed to analyse the relationship between arterial hypertension and changes in arterial blood flow and vascular wall damage of the lower limbs in hypertensive patients with various degrees of hypertension. Six hundred and fifty-four hypertensive patients (421 males and 233 females) aged 35 to 70 years and 88 healthy subjects (63 males and 25 females) aged 39 to 60 years were studied. Strain-gauge plethysmography of the lower limbs was used to calculate arterial calf blood flow (RF), arterial calf blood flow after post-ischaemic hyperaemia (PF), basal and minimal vascular resistances (BVR and MVR), time to reach peak flow (tPF), time until 50% reduction of peak flow (tT1/2)…

Bystander trauma care—effect of the level of training

2003

Background: The bystander is often the first person present at the scene of an accident. Our aim was to determine how often and how well bystanders perform trauma care and whether trauma care is affected by the bystander’s level of training, relationship to the patient and numbers of bystanders present. Patients and methods:In a prospective 1-year study, the emergency medical service in two European cities collected data on trauma calls. Questionnaires were used to document the bystanders’ level of training (none, basic, advanced, professional), the bystander’s relationship to the patient, and the number of bystanders present, and to assess whether five separate measures of trauma care (ens…

Rosuvastatin Prevents Conduit Artery Endothelial Dysfunction Induced by Ischemia and Reperfusion by a Cyclooxygenase-2–Dependent Mechanism

2010

ObjectivesThe purpose of this study was to determine whether single-dose rosuvastatin (40 mg) protects against ischemia and reperfusion (IR)–induced endothelial dysfunction in humans and whether this effect is cyclooxygenase (COX)-2 dependent.BackgroundAnimal studies have demonstrated that rosuvastatin can limit damage and improve recovery after IR.MethodsIn a double-blind, parallel design, 20 volunteers were randomized to a single dose of oral rosuvastatin (40 mg) or placebo. Twenty-four hours later, endothelium-dependent, flow-mediated dilation (FMD) of the radial artery was measured before and after IR (15 min of upper arm ischemia followed by 15 min of reperfusion). In a separate protoc…
