Diagnosis of myocardial infarction is very important in a patient with chest pain. Chest pain is not always present or it may be from other causes rather than myocardial infarction. Q wave is present in 30] of infarction. ST,T wave changes are present in all myocardial infarctions, but these changes also are present in myocardial ischernia.  For these reasons diagnosis of myocardial infarction...

Acute coronary syndrome (ACS) refers to any constellation of clinical symptoms that are compatible with acute myocardial ischemia. ACS is divided into ST- elevated myocardial infarction (STEMI), non-ST elevated myocardial infarction (NSTEMI), and unstable angina (UA). STEMI results from complete and prolonged occlusion of an epicardial coronary blood vessel and is defined based on ECG criteria....

The need for emergency cardiac bypass surgery due to a complication occurring during a PCI procedure has gone down from an initial 6–10 % in the early 1980s to less than 0.5 % in the present era [1]. Technological advances have made the procedure very safe in the hands of experienced operators working in dedicated centres. In Europe in the last decade, many PCI programs without surgery on-site ...

BACKGROUND Current cardiovascular magnetic resonance (CMR) methods, such as late gadolinium enhancement (LGE) and oedema imaging (T2W) used to depict myocardial ischemia, have limitations. Novel quantitative T1-mapping techniques have the potential to further characterize the components of ischemic injury. In patients with myocardial infarction (MI) we sought to investigate whether state-of the...

INTRODUCTION So far, no studies have been performed regarding the epidemiology and management of acute coronary syndromes (ACS) in Cyprus. The aim of the present study was to enroll a representative sample of patients in order to study the epidemiology and management of ACS in the Mediterranean island of Cyprus. METHODS For a period of 12 months, all patients admitted to Nicosia General Hospi...

The aim of this study was to investigate the level of job satisfaction among supermarket workers. A self administered questionnaire survey was conducted from July-September 2007. Data were collected from 111 supermarket workers in a major supermarket located in Vieux Fort, Saint Lucia. Respondents were asked to complete a 10-item job satisfaction questionnaire. The response rate was 74%. The pe...

This study investigates the geometric accuracy of DSMs and orthoimages, which are obtained from high resolution satellite stereo pairs of in-track, cross-track and mixed satellite images. Four IKONOS and two QuickBird panchromatic images are used to constitute 15 stereo pairs, and are processed to generate DSMs and orthoimages. A geometric stereo model, which represents the stereo acquisition g...

Objective The videofluoroscopic swallow study (VFSS) is the gold standard diagnostic tool to evaluate oropharyngeal dysphagia. Although objective measurements on VFSS have been described, there is no universal method of analysis, and the majority of clinicians use subjective interpretation alone. The purpose of this investigation was to evaluate the accuracy of subjective VFSS analysis. Study D...

The cost of antiretrovirals is borne by donors in many low- and middle-income countries, including St Lucia. Although donor involvement has facilitated access to antiretrovirals, donor engagement in HIV/AIDS has changed over the years. This paper assesses the affordability of antiretrovirals at the individual level if donors were no longer available to fund the cost of first and second-line ant...
