In general, cardiac involvement is a marker of poor prognosis. [26, 27] Therefore, any clinical, laboratory or imaging abnormality that suggests increased cardiac involvement will be indicative of a worse prognosis. No consensus has been reached about a single most important prognostic factor. The factors associated with a poor prognosis include the following:

  • Syncope

  • Complex arrhythmia

  • Degree of left ventricular (LV) hypertrophy (More = worse prognosis)

  • Low LV ejection fraction (LVEF)

  • Restrictive hemodynamic

  • Right ventricular dilatation

  • Pulmonary hypertension

  • Low voltage on electrocardiography (ECG)

  • High brain natriuretic peptide (BNP) levels

  • High troponin levels

  • T1 kinetics on gadolinium-enhanced magnetic resonance imaging (MRI) (to demonstrate extent of myocardial involvement)
