Table 1 Features of myocardial involvement in systemic sclerosis distinct from coronary atherosclerotic disease
Characteristic features
Microvascular ischemia
Patchy fibrosis, unrelated to coronary epicardial artery distribution
Involvement of immediate subendocardium, which is spared in atherosclerosis
Contraction band necrosis
Concentric intimal hypertrophy associated with fibrinoid necrosis of intramural coronary arteries
Hemosiderin deposits are not typically seen; they are evident in the atherosclerotic process
