In medicine and physiology, diastolic heart failure or diastolic dysfunction is "[a subset of] heart failure caused by abnormal myocardial relaxation during diastolic leading to defective cardiac filling."[1]
A working definition is heart failure without systolic dysfunction.[2] Up to 40% of patients with heart failure may not have evidence of systolic dysfunction.[2]
Diastolic dysfunction usually occurs in the setting of structural heart disease such as either a reduced ejection fraction, enlarged left atrium, or left ventricular hypertrophy.[3]
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).[4]
The the ratio of peak early (E) or passive diastolic filling and peak atria1 (A) velocities (E/A ratio) of < 0.6 is less sensitive.[5]
Echocardiography may grade the severity of diastolic dysfunction, parameters include:[6]
- Mild:
- E/A ratio <0.8
- E/e′ ratio < 8
- Moderate (grade II; "impaired myocardial relaxation with mild to moderate elevation of LV filling pressures"):
- E/A ratio 0.8 to 1.5 (pseudonormal)
- E/e′ (average) ratio is 9 to 12
- Severe (grade III; "restrictive LV filling occurs"):
- E/A ratio ≥ 2
- E/e′ (average) ratio > 13
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.[7]
Prognosis
Diastolic dysfunction, even in the absence of clinical heart failure, increases mortality.[8] E/e' (early mitral annular velocity) may be best predictor.[9]
