Coronary microvascular dysfunction in systemic sclerosis: insights from PET-derived myocardial flow reserve.
Cardiovascular death is the second leading cause in systemic sclerosis (SSc), with coronary microvascular dysfunction (CMVD) playing a key role. PET-derived myocardial blood flow (MBF) and flow reserve (MFR) offer a validated, non-invasive way to assess CMVD. We studied the prev…
