When chest symptoms recur in a patient who underwent percutaneous transluminal coronary angioplasty (PTCA), it is necessary to rule out restenosis (R). Three main noninvasive tests suggest the presence of R: exercise stress test (XT), myocardial perfusion imaging (MPI) and stress echocardiography (s-echo). The objectives of this review were: (1) to estimate the pretest probability of R as a fun...

conclusions: rsbi and apache ii score in patients with copd exacerbation are of the ability to predict niv requirement, as a predicting factor of non-invasive ventilation requirement. results: patients requiring niv included 43.9 % of all studied patients. rsbi and apache ii score with sensitivity of 94.8 %, (cut off point = 110) and 72 % (cut off point = 14) respectively, had high diagnostic s...

Acute chest pain as a presenting syndrome in the emergency department is by far one of the most prevalent worldwide. Validation of several diagnostic-imaging modalities for this syndrome has been the focus of several research groups over the last 3 decades. Unfortunately, from the simple and inexpensive exercise stress electrocardiography to the most advanced and complex tests such as positron ...

T he diagnosis and subsequent management of coronary artery disease (CAD) represents a major challenge to our healthcare systems, affecting millions of patients each year. Despite many years and literally thousands of publications, the optimal approach for the evaluation of stable ischemic heart disease remains unclear. Functional or stress testing to detect inducible ischemia has been the “gol...

1) Coronary artery disease in women differs from men in several ways, including their response to many diagnostic tests.2) Strong comparative data on stress echocardiography for detecting coronary artery disease in women are lacking, but existing data consistently show sensitivity comparable with other high-sensitivity tests and superior specificity, increasing its diagnostic accuracy.3) Pharma...

abstract background: one of the main causes of stress in the lives of people is their jobs. occupational stress is causing a wide range of significant issues in health and community services. nursing is the most stressful profession in the health services. massage therapy is one way of coping with stress. this study was conducted to determine the effect of massage therapy on stress in nurses. m...

Atherosclerosis is a chronic inflammatory disease that affects essentially all arterial beds including the aorta, coronaries, carotids, and peripheral arteries. It is the main cause of death in the western hemisphere, due to cardiovascular syndromes such as myocardial infarction, heart failure, and cerebrovascular accidents. Very substantial economic and human resources have been used on treatm...

CONTEXT Stress is defined as an alteration of an organism's balance in response to a demand perceived from the environment. Diverse methods exist to evaluate physiological response. A noninvasive method is salivary measurement of cortisol and alpha-amylase. A growing body of evidence suggests that the regular practice of Yoga would be an effective treatment for stress. AIMS To determine the K...

The objective of the study was to examine the influence of angiotensin converting enzyme (ACE) inhibition on circulatory responses to standardized stress tests in primary mild to moderate hypertension. Patients (n = 28) received 5 mg ramipril daily or placebo for 6 weeks in a double-blind crossover design, followed by 6 months of open ramipril treatment. Mental stress (a 20-min Stroop's color w...
