Table 1 The risk factor in patients with systolic heart failure

From: Role of echocardiography in diagnosis and risk stratification in heart failure with left ventricular systolic dysfunction

  Abnormality
  Mild Moderate Severe
LV end-systolic volume (ml/m2) <30 30–60 >60
LV ejection fraction (%) 45–54 44–30 <30
Transmitral LV diastolic dysfunction (E/A) Grade I Grade II-III Grade IV
Tissue Doppler diastolic dysfunction (E/E') <8 8–15 >15
Ultrasound Lung Comets 5–15 16–30 >30
Mitral regurgitation (Jet/left atrial) <20 20–40 >40
