Prevalence of Diastolic Dysfunction in Critically Ill Patients Admitted to Intensive Care Unit from a Tertiary Care...

Critically ill individuals may have left ventricular diastolic dysfunction (LVDD) which can prolong their intensive care unit (ICU) stay. The purpose of this study was to determine the prevalence of LVDD in critically ill adult patients requiring mechanical ventilation in ICU, the effect of LVDD on 28-day survival, and weaning from mechanical ventilation.

A total of 227 adults who had been on mechanical ventilation for more than 48 hours in an ICU were recruited for this study. The study's parameters were recorded on the third day of mechanical ventilation using a low-frequency phased array probe. A simplified definition of LVDD in critically ill adults was utilized to determine the presence or absence of LVDD. Weaning failure and 28-day mortality were noted.

The prevalence of LVDD in adults requiring mechanical ventilation in the ICU was found to be 35.4% (n = 79). Patients with LVDD had the odds of having a 28-day mortality increase by 7.48 (95% CI: 3.24-17.26, p < 0.0001). Patients with LVDD had the odds of having weaning failure increase by 5.37 (95% CI: 2.17-13.26, p = 0.0003).

Measures should be taken to detect critically ill adults with LVDD with systolic dysfunction or heart failure with preserved ejection fraction early so that their fluid balance, myocardial contractility, and afterload can be optimized to minimize their morbidity and mortality.

Critically ill adults with LVDD may have adverse outcomes. Hence, protocol should be in place for diagnosing LVDD early in critically ill adults thereby, measures can be taken to minimize morbidity in those patients.
