Summary
Malnutrition, identified by the Controlling Nutritional Status (CONUT) score, is a significant predictor of in-hospital mortality in patients with acute pulmonary embolism. This finding highlights the importance of nutritional assessment in managing PE patients.
Area of Science:
- Cardiology
- Internal Medicine
- Nutritional Science
Background:
- The prognostic implications of nutritional status in acute pulmonary embolism (PE) remain incompletely understood.
- The Controlling Nutritional Status (CONUT) score is a validated tool for assessing malnutrition based on albumin, total cholesterol, and lymphocyte counts.
Purpose of the Study:
- To evaluate the utility of the CONUT score in identifying malnutrition among patients hospitalized with acute PE.
- To determine if the CONUT score can predict in-hospital mortality in this patient population.
Main Methods:
- A retrospective review of 308 adult patients admitted with acute PE was conducted.
- Demographic, clinical, and laboratory data were collected upon admission.
- Nutritional status was assessed using the CONUT score, and its association with in-hospital mortality was analyzed.
Main Results:
- The study included 308 patients, with an in-hospital mortality rate of 11.4% (35 deaths).
- Multivariate analysis identified a high Pulmonary Embolism Severity Index (>148), heart failure, and a CONUT score >4 as independent predictors of in-hospital mortality.
- A CONUT score >4 was associated with an increased risk of in-hospital mortality (OR 1.39, p = 0.015).
Conclusions:
- The findings suggest that malnutrition, as indicated by the CONUT score, is a significant independent predictor of in-hospital mortality in patients with acute pulmonary embolism.
- Nutritional status assessment using the CONUT score may aid in risk stratification and management of acute PE patients.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

51
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

53
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...
