Sudden cardiac death (SCD) of an athlete is a rare but tragic event and sport activity might play a trigger role in athletes with underlying structural or electrical heart diseases. Preparticipation screenings (PPs) have been conceived for the potential to prevent SCD in young athletes by early identification of cardiac diseases. The European Society of Cardiology protocol for PPs includes history collection, physical examination and baseline electrocardiogram, while further examinations are reserved to individuals with abnormalities at first-line evaluation. Nevertheless, transthoracic echocardiography has been hypothesized to have a primary role in the PPs. This review aims to describe how to approach an athlete-focused echocardiogram, highlighting what is crucial to focus on for the different diseases (cardiomyopathies, valvulopathies, congenital heart disease, myocarditis and pericarditis) and when is needed to pay attention to overlap diagnostic zone (“grey zone”) with the athlete's heart. Once properly tested, focused echocardiography by sports medicine physicians may become standard practice in larger screening practices, potentially available during first-line evaluation.
The quick evaluation of venous thromboembolism is a key point of modern medicine since the delayed diagnosis is associated with a worse prognosis. Venous ultrasound (VU) is a sensitive and rapidly performed test in cases of suspected deep venous thrombosis. Various protocols have been proposed for its execution, such as the study of the whole deep venous circulation of the lower limb or the analysis of the femoral-popliteal area. The aim is to detect a vessel thrombus and the most sensitive element is the non-compressibility with the probe. Initially, the thrombus is hypoechogenic and adherent to the vessel; later, it tends to organize and recanalize. Usually, in the early stages, the risk of embolism is higher. The role of studying the iliac axis and calf veins is still uncertain. VU is not useful for assessing response to anticoagulation therapy and it is unclear whether the persistence of thrombotic abnormalities can guide on a possible prolongation of therapy.
Heart involvement in Cardiac Amyloidosis (CA) results in a worsening of the prognosis in almost all patients with both light-chain (AL) and transthyretin amyloidosis (ATTR). The mainstream CA is a restrictive cardiomyopathy with hypertrophic phenotype at cardiac imaging that clinically leads to heart failure with preserved ejection fraction (HFpEF). An early diagnosis is essential to reduce cardiac damage and to improve the prognosis. Many therapies are available, but most of them have late benefits to cardiac function; for this reason, novel therapies are going to come soon.
Aims The real effects of the chronic consumption of anabolic–androgenic steroids (AAS) on cardiovascular structures are subjects of intense debate. Aim of the study was to detect by speckle tracking echocardiography (STE) right ventricular (RV) and left ventricular (LV) dysfunction at rest and during exercise stress echocardiography (ESE) in athletes abusing AAS. Methods and results 115 top-level competitive bodybuilders were selected (70 males), including 65 athletes misusing AAS for at least 5 years (users), 50 anabolic-free bodybuilders (non-users), compared to 50 age- and sex-matched healthy sedentary controls. Standard Doppler echocardiography, STE analysis, and lung ultrasound at rest and at peak supine-bicycle ESE were performed. Athletes showed increased LV mass index, wall thickness, and RV diameters compared with controls, whereas LV ejection fraction was comparable within the groups. LA volume index, LV and RV strain, and LV E/Em were significantly higher in AAS users. Users showed more B-lines during stress (median 4.4 vs. 1.25 in controls and 1.3 in non-users, P < 0.01 vs. users). By multivariable analyses, LV E/Ea (beta coefficient = 0.35, P < 0.01), PASP (beta = 0.43, P < 0.001) at peak effort, and number of weeks of AAS use per year (beta = 0.45, P < 0.001) emerged as the only independent determinants of resting RV lateral wall peak systolic two-dimensional strain. In addition, a close association between resting RV myocardial function and VO2 peak during ESE was evidenced (P < 0.001), with a powerful incremental value with respect to clinical and standard echocardiographic data. Conclusions STE represents a promising technique to assess RV myocardial function in athletes abusing steroids. AAS users showed a more impaired RV deformation, closely associated with reduced functional capacity during physical effort, and—during exercise—more pulmonary congestion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
