Description
Summary:Abstract A wide spectrum of topics regarding Multiple Sclerosis (MS) have been thoroughly studied, like immunology, nature of demyelinating lesions (DL's), therapeutics, etc. However, little is known about the influence of MS DL's on the cardiovascular system and especially in the coronary vasculature although few reports mention coronary vasospasm due to autonomic nervous system (ANS) abnormalities. Aim of this study was the detection the presence of Neurogenic Stunned Myocardium (NSM) through perfusion test. Method We enrolled 50 asymptomatic fulfilling the criteria MS patients, aged 45±7 years old and disease in our study duration of 6±13 years with EDSS= 2,5. After echocardiography and clinical examination as primary screening, pharmacologic stress thallium 201 scintigraphy and/or coronary angiography were performed to identify the incidence of NSM. Clinical characteristics of MS, type of disease, treatments as well as localization of demyelinating plaques (DP) were noted. Results 13 patients (26%) had abnormal scintigraphy test although clinical profile was not indicative. Cardiac ultrasound showed that 2 patients from this group had a critical ejection fraction (around 50%). All positive patients that underwent for coronary angiogram were negative implying coronary artery spasm as a potential mechanism for the stress positive result. A common finding of all positive patients was the localization of DP which was in the lateral horn of the lower cervical part (C5–7) and upper thoracic part (Th1–4). No correlation seems to have the presence of CAD with disease duration, EDSS and treatment approaches. Discussion Our study shows a high incidence of NSM. This finding due to the location of the DP seems to correlate with ANS disturbance and might help to distinguish patients at higher risk.
