About

The goal is to assess for myocardial edema on cardiac MRI during SLE flare to assess for myocardial inflammation.

Full description

The over-arching goal of this work is to further the understanding of myocardial damage in systemic lupus erythematosus (SLE) using state of the art CV imaging to investigate a novel potential mechanism of CV injury in SLE, subclinical myocardial inflammation. Aim 1: Investigate an alternative pathway for CV morbidity in SLE by measuring myocardial edema at time of moderate to severe flare and compare values to post-flare studies and historical healthy controls. Hypothesis 1: Myocardial edema, measured quantitatively with T2 CMR mapping during moderate to severe SLE flare will be significantly increased compared to 1) historical controls and 2) in SLE patients after resolution of flare. Aim 2: Perform exploratory analyses investigating relationships between myocardial edema on CMR and markers of SLE disease activity and CV risk factors. Hypothesis 2: Markers of disease activity including inflammatory makers (ESR and high sensitivity c-reactive protein), complement and autoantibody levels will predict the presence of T2 CMR detected myocardial edema during flare.

Inclusion criteria

• Diagnosis of SLE by American College of Rheumatology Classification Criteria [21]

Active SLE Flare defined by Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)[22] > 6 or British Isles Lupus Assessment Group (BILAG) Index A or B.[23]

Exclusion criteria

  • Pregnant
  • Allergy to gadolinium
  • Severe claustrophobia
  • Renal replacement therapy or glomerular filtration rate (GFR) < 30 mL/min/1.75m²
  • Medically unstable for transportation to Ross MRI scanner. Stability will be defined as: not on mechanical ventilation, HR < 120 BPM, MAP > 65 mmHg. The treating providers' input on the patient's stability will also be considered in addition to these criteria
  • Weight > 500 pounds
  • MR incompatible implanted devices such as neurostimulator pacemakers and implantable defibrillators, presence of intracranial metal or any metal not compatible with CMR
