Abstract

The phase angle (PA) has been considered a sensitive tool to assess nutritional status and effectiveness of interventions dietetics. To evaluate the PA as an indicator of nutritional status and prognosis in critically ill patients. Prospective observational study of patients admitted to the Coronary Intensive Care Unit between May and October 2013. The PA was determined by bioelectrical impedance analysis, PA was considered low below 5º values for men and 4.6º for women. The values obtained were related to other evaluation parameters of nutritional status: anthropometric (arm circumference - AC , triceps skinfold thickness - TST , corrected arm muscle area - AMAc and calf circumference - CC) and biochemical (total lymphocyte count, hemoglobin, hematocrit), in addition to clinical prognostic APACHE II (Acute Physiology and Chronic Health Disease Classification System II) and serum albumin. The tabulation and analysis were performed using SPSS version 13.0. The sample consisted of 110 patients, in which an association was found between low AF and renal failure on dialysis (p < 0.001), % adequacy AC (p = 0.028), % adequacy of TST (p = 0.043), albumin level (p = 0.042), anemia (p = 0.040) and APACHE II (p = 0.012) scores. The AF wa...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
