Background:Cardiovascular disease is the leading cause of morbidity and mortality worldwide. Myocardial calcifications have been related with cardiovascular diseases (CVD) such as focal wall motion abnormalities and arrhythmias. The impact of vascular calcifications is under investigation in order to define the risk of cardiovascular events. The relationship between cardiac calcification and systemic sclerosis (SSc) has not been investigated.Objectives:The aim of the study is to evaluate the frequency of different patterns of cardiac calcification in SSc patients, and to correlate them to other CVD risk factors.Methods:We analyzed thoracic-CT scanners of 35 SSc patients (88% female, aged 47,8 ys ±12,9, disease duration 12,8 ys ±9) to determine the location and extension of vascular and cardiac calcification. All recruited patients fulfilled the 2013 ACR-EULAR classification criteria for SSc. No one patients had renal failure, cardiomyopathy, myocarditis, history of cardiac surgery or radiotherapy.Results:We found myocardial vessels calcifications (MCv) in 37% SSc patients, aortic wall calcifications (ACw)in 60% SSc patients, cardiac valve calcifications (VC) in 28% SSc patient and heart wall calcifications (HCw) in 20%.The SSc patients with almost one calcification had older age (65±9,8 ys vs 50±8,8 ys; p=0,0001) and higher values of circulating NTproBNP (336,9±351,9 vs 144,2±107,8; p=0,04) compared to those without.In particular, the SSc patients with MCv had and uric acid (5,3 ±1,5 vs 4,1 ±1,3; p=0,05), higher rate of PAH (25% vs 0%; p=0,037), arrhythmia (38,5% vs 9%; p=0,036) and higher prevalence of CENP-B antibodies(46% vs 4%; p=0,01) compared to patients without MCv.Patients with HCw had lower C reactive protein (0,16 ±0,10 vs 0,7±0,7; p=0,008) compared to those without HCw. No differences in the rate of heart and vascular complications of SSc were observed.The SSc patients with ACw had higher frequency of arrhythmia (33% vs 0%; p=0,016) and longer disease duration (15,5 y ±9,9 vs 8,8 ±5,8; p=0,03).The SSc patients with VC had higher rate of PAH (33%vs0%; p=0,003) and uric acid (6±0,5vs3,8±1,2 p=0,0001).Regression analysis excluded any association with gender, BMI, systemic arterial hypertension, steroid therapy, hypovitaminosis D or smoke habit. No cardiovascular event was recorded in one year of observation.Conclusion:All patterns of calcifications may be related mostly with the older age. Myocardial vessels calcifications have been found in a high percentage of SSc patients and in particular in those with PAH and positive for anti CENP-B. Furthermore, myocardial vessels calcifications could be associated to the higher occurrence of arrhythmia. More studied are needed to assess the importance of vascular calcification as a part of the vascular involvement in SSc.References:[1]John W. Nance Jr. MD.
