Poor Nutritional Status Is Associated with Arrhythmic Events on 24-Hour Holter Recording.

Background: Malnutrition is associated with cardiovascular disease morbidity and mortality. Arrhythmias may be the cardiac consequences of malnutrition.

Objectives: The objective of the study was to evaluate the association between prognostic nutritional index (PNI), Controlling Nutritional Status (CONUT) score, and arrhythmic events on 24-h electrocardiography (ECG) Holter recording in patients without manifested arrhythmia.

Prognostic Nutritional Index as a New Prediction Tool for Coronary Collateral Development.

Background: Nutritional status is a predictor of the prognosis of cardiovascular diseases. The association between the Prognostic Nutritional Index (PNI), which is an immunonutritional parameter, and cardiovascular diseases has been extensively studied in the literature.

Objectives: The aim of this study was to investigate whether PNI is associated with coronary collateral development.
