low cardiac out put

Enrico Paolini, Elettra Conti, Federico Guerra, Alessandro Capucci
BACKGROUND: Despite the many recent improvements in basic life support (BLS) and the widespread training to a great number of lay rescuers, out-of-hospital cardiac arrest (OHCA) is still a major cause of death. Nowadays, BLS teaching protocols ask for many concepts to be learned and specific algorithms to be applied, without any available data on how much all these inputs are retained by the students. The present survey aims to evaluate how BLS is really retained by those rescuers (laypersons and nurses) who do not often put it into practice...

OBJECTIVE: To determine whether admission, and provocative stress testing of patients who have ruled out for acute coronary syndrome put patients with low-risk category for coronary artery disease (CAD) at risk for false-positive provocative stress testing and unnecessary coronary angiogram/imaging. METHODS: A retrospective chart review was performed on patients between 30 and 70 years old, with no pre-existing diagnosis of CAD, admitted to observation or inpatient status chest pain or related complaints...

Out-of-hospital cardiac arrest (OHCA) is a major health problem that affects approximately four hundred and thousand patients annually in the United States alone. It is a major challenge for the emergency medical system as decreased survival rates are directly proportional to the time delay from collapse to defibrillation. Historically, defibrillation has only been performed by physicians and in-hospital. With the development of automated external defibrillators (AEDs), rapid defibrillation by nonmedical professionals and subsequently by trained or untrained lay bystanders has become possible...

The onset of lactation marks a significant turning point in a heifer's life, and prior experience with the milking routine could have positive effects on animal welfare and productivity. The objectives of this multifarm (n=5) study were to investigate (1) whether prelactation training sessions affected behavior during milking, cardiac activity, human avoidance distance, and milk yield, and (2) whether these responses would be modified by the heifer's initial level of fear of humans. Trained heifers (TH, n=30) experienced the routine in the milking parlor on at least 10 d prepartum, whereas untrained heifers (UH, n=29) entered the parlor for the first time after calving...

BACKGROUND: The management of coronary artery bypass graft (CABG) patients, especially in high risk patients ,can be challenging as the postoperative periods may be characterized by a low cardiac output state. Inotropes used in the perioperative periods to increase cardiac output may be detrimental thus making the use of mechanical devices like intra-aortic Balloon pump (IABP) for circulatory assistance desirable. AIMS & OBJECTIVES: To study the use of intra-aortic balloon pump in coronary artery bypass patients in preoperative and post operative settings and factors that affect morbidity and mortality...

Electrical burns are classified as either high voltage (1000 volts and higher) or low voltage (<1000 volts). The typical injury with a high-voltage electrical contact is one where subcutaneous fat, muscles, and even bones are injured. Lower voltages may have lesser injuries. The electrical current has the potential to injure via three mechanisms: injury caused by current flow, an arc injury as the current passes from source to an object, and a flame injury caused by ignition of material in the local environment...

UNLABELLED: We report a case of a giant ovarian cyst and its removal by means of a newly and low morbid technique. It's about a 40 years-old female with intervascular closing cardiovascular surgery history, 25 years before, and one pregnancy and one delivery. She has two years development of middle effort dyspnea, weight gain and abdominal distension. Physical examination reveals a weight of 160 kg, 1.60 m of height, mild teguments paleness, and walkinf difficulty due to its grate distension; blood pressure was 150/70 mmHg, cardiac frequency of 95 bpm, I to II grade systolic murmur at the aortic focal accessory (in a I to VI scale), hypoventilated lung fields, grate abdominal distension, mild percussion pain, and low peristalsis...

Cost containment and efficient resource utilization are motivating anaesthesiologists to early tracheal extubation of cardiac surgical patients. Fast track cardiac anaesthesia is both safe and cost-effective. We studied 45 patients with LVEF = 40% who underwent coronary revascularization and were put on the same fast track principle as those with normal ventricular function. Of these 31 patients (68.8%) had recent (<2 weeks) cardiac events requiring hospitalization. Acute myocardial infarction was documented in 8 patients (17...

HISTORY: A 36 year-old man suffered from fever, fatigue, pleurodynia and precordial discomfort. His family physician suspected febrile tracheobronchitis and treated it with ampicillin for 5 days. Because symptoms persisted an ECG was done which suggested acute myocardial infarction. The patient underwent an emergency coronary angiography which excluded coronary artery disease and aortic dissection. Pericarditis was suspected and the patient put on aspirin, 500 mg/d. Because of persisting cardiac symptoms an echocardiography was performed which revealed systolic separation between epi- and pericardium, characteristic of a small pericardial effusion after acute pericarditis...

Batteries of individually standardized physical and functional tests are commonly used to assess persons with chronic back pain disability. The order of testing may affect performance on later tests. One hundred and fifty patients with > 3 months of back pain disability underwent a multidisciplinary Spine Team Assessment involving Physical Therapy, Occupational Therapy, Pain Psychology, and Vocational Rehabilitation Counselor assessments at a university spine clinic. Seventeen back healthy volunteers performed the physical component of the assessment...

After weaning from PMV, patients are usually far from ready to resume normal activities. A prolonged recovery period after catastrophic illness is the rule, with multidisciplinary rehabilitation and discharge planning efforts. Following such efforts, reports of success of restorative care are institutional and population specific. That all PMV patients are not "chronically critically ill" introduces selection factors that make comparisons between institutions even more difficult. Half of the authors' patients were able to go home in past years [14], although more recently, with patients admitted more debilitated and more ill, the percent returning home has gradually declined to the low 20% range...

Interest in the functions of intracellular chloride expanded about twenty years ago but mostly this referred to tissues other than smooth muscle. On the other hand, accumulation of chloride above equilibrium seems to have been recognised more readily in smooth muscle. Experimental data is used to show by calculation that the Donnan equilibrium cannot account for the chloride distribution in smooth muscle but it can in skeletal muscle. The evidence that chloride is normally above equilibrium in smooth muscle is discussed and comparisons are made with skeletal and cardiac muscle...

OBJECTIVES AND METHODS: Chlorination has been the major disinfectant process for domestic drinking water for many years. Concern about the potential health effects of the byproducts of chlorination has prompted the investigation of the possible association between exposure to these byproducts and incidence of human cancer, and more recently, with adverse reproductive outcomes. This paper evaluates both the toxicological and epidemiological data involving chlorination disinfection byproducts (DBPs) and adverse reproductive outcomes, and makes recommendations for future research...

Thiamine deficiency is one of the classical causes of high out put for heart failure. Deficiency of this vitamin may be nutritional or secondary to alcoholic intoxication. We felt it would be interesting to describe a typical case of cardiac beriberi in order to recall the clinical presentation and the pathophysiology.

The aim of this study was to investigate spontaneous variability of arterial blood pressure in conscious foxhounds in the absence of direct sympathetic and parasympathetic influences. Autonomic blockade was achieved by administration of the ganglionic blocking agent hexamethonium (n = 7). In contrast to the control group (n = 7), marked oscillations with a cycle length of 100 s (0.01 Hz) were observed. The relationship of the power densities of the oscillation band (0.01 +/- 0.005 Hz) to the total power increased threefold (0...

Coronary artery disease and ischemic myocardial damage form the most common cause of failure of the heart to pump enough blood for oxygenation of the body at a healthy blood pressure and at a low pressure in the veins. This paper gives an overview of the mechanisms involved in excitation-contraction coupling which are important to control of the force of the heartbeat. The inability of the heart in failure to eject a sufficient amount of blood in order to meet the needs of the body is thought to result from molecular changes in cardiac cells causing decreased active (systolic) force and impaired (diastolic) relaxation together with a greater stiffness of the remodelled ventricular wall...
