Diastolic dysfunction in primary care: medical and nursing interlocutions

To evaluate the ratio between early and late mitral filling velocities (E/A) as a prognostic factor for hospitalizations due to cardiovascular causes and mortality in primary care; to identify the main NANDA-I nursing diagnoses, interventions, and outcomes associated with diastolic dysfunction.

633 individuals were recruited for evaluation of the E/A ratio and characterization of diastolic dysfunction. Multivariate Cox regression with Schoenfeld residual analysis, survival analysis, and hazard ratio estimation were performed.

After six years, crude hazard ratios of 3.47, 3.60, 3.02, and 0.41 were identified for classes II and III diastolic dysfunction at cut-off points 1 and 2, respectively (p<0.01). Nursing diagnoses of Activity Intolerance, Anxiety, Fatigue, and Deficient Knowledge should be prioritized.

The E/A ratio showed an altered pattern in most participants without a diagnosis of heart failure, which may indicate a subclinical form of the condition.
