- pericardium, pericarditis 25% most common
- myocardium, myocarditis is rare caused by vasculitis
- myocardial infarction 9X increase
- endocardium – Libman-Sacks 10% mitral and tricuspid valve
- Cardiac complications in about 50% and major cause of death
occurs in nearly 10% of SLE patients and serves as a prominent contributor of the heart failure (HF) and poor prognosis 8, 29 and is caused by vasculitis with with microvascular coronary dysfunction. SLE myocarditis is an immune complex-mediated process.
The LGE is characterized by patchy and small areas in the midwall and subepicardial myocardium in both the both acute and chronic phases4
Varied valve involvement, including valve thickening (fibrosis or calcification), leaflet perforation, stenosis, valve regurgitation and valve mass (Libman-Sacks vegetations) can be found in all valves in the heart 47. However, the mitral valve is most vulnerable.
Increased risk of CAD
lipid dysfunctions can accelerate the progression of overall atherosclerotic burden 4
SLE patients had a higher calcification score compared to controls
- mid ventricular
- also vascular distribution because of vasculitis (subepicardial
