Speckle tracking echocardiography as a new diagnostic tool for an assessment of cardiovascular disease in rheumatic patients.

Chronic inflammation represents the cornerstone of the raised cardiovascular (CV) risk in patients with inflammatory rheumatic diseases (IRD). Standardized mortality ratios are increased in these patients compared to the general population, which can be explained by premature mortality associated with early atherosclerotic events. Thus, IRD patients need appropriate CV risk management in view of this CV disease (CVD) burden. Currently, optimal CV risk management is still lacking in usual care, and early diagnosis of silent and subclinical CVD involvement is mandatory to improve the long-term prognosis of those patients. Although CV involvement in such patients is highly heterogeneous and may affect various structures of the heart, it can now be diagnosed earlier and promptly treated. CV imaging provides valuable information as a reliable diagnostic tool. Currently, different techniques are employed to evaluate CV risk, including transthoracic or trans-esophageal echocardiography, magnetic resonance imaging, or computed tomography, to investigate valve abnormalities, pericardial disease, and ventricular wall motion defects. All the above methods are reliable in investigating CV involvement, but more recently, Speckle Tracking Echocardiography (STE) has been suggested to be diagnostically more accurate. In recent years, the role of left ventricular ejection fraction (LVEF) as the gold standard parameter for the evaluation of systolic function has been debated, and many efforts have been focused on the clinical validation of new non-invasive tools for the study of myocardial contractility as well as to characterize the subclinical alterations of the myocardial function. Improvement in the accuracy of STE has resulted in a large amount of research showing the ability of STE to overcome LVEF limitations in the majority of primary and secondary heart diseases. This review summarizes the additional value that STE measurement can provide in the setting of IRD, with a focus in the different clinical stages.
