In medicine and physiology, diastolic heart failure or diastolic dysfunction is "heart failure caused by abnormal myocardial relaxation during diastolic leading to defective cardiac filling."[1]
Diagnosis
| Finding | Sensitivity | Specificity |
|---|---|---|
| Mitral annular velocity (E/e') > 13 mm Hg | 70% | 93% |
| Left atrial volume index (LAVi) > 31 mL/m2 | 78% | 76% |
| Pulmonary artery systolic pressure (PAP) | 80% | 64% |
| E/e' or LAVi* | 87% | 88% |
| Notes: * E/e' > 13 mm Hg or LAVi > 31 mL/m2 with E/e' > 7 mm Hg | ||
Echocardiography may detect diastolic heart failure (see table).[2]
Treatment
Digoxin may reduce the combined outcome of death or hospitalization due to worsening heart failure according the results of the ancillary trial of patients with preserved ejection fraction in a larger randomized controlled trial of treating patients with heart failure.[3]
