In hypertensive patients, STE provides more detailed information than conventional echocardiography and TDI, since it reveals a systolic dysfunction before hypertrophy occurs (Stage A of ACC/AHA classification of HF) and identifies some early LV mechanic changes that might improve the clinical management of these patients.

Data obtained indicated viral infection as a potential trigger and sometimes as the main etiologic agent in causing acute or chronic urticaria. In every case, urticarial manifestation cleared up after either healing or controlling of the viral infection. However, prospective studies and well-structured research is needed to better clarify the role of viruses in the pathogenesis of urticaria and their relative prevalence.

Our findings show that local and systemic arterial stiffness are increased in asymptomatic, normotensive HCh children, suggesting that HCh plays a key role in arterial mechanical impairment since the paediatric age.

Introduction Some local protocols suggest using intermediate or therapeutic doses of anticoagulants for thromboprophylaxis in hospitalized patients with coronavirus disease 2019 (COVID‐19). However, the incidence of bleeding, predictors of major bleeding, or the association between bleeding and mortality remain largely unknown. Methods We performed a cohort study of patients hospitalized for COVID‐19 that received intermediate or therapeutic doses of anticoagulants from March 25 to July 22, 2020, to identify those at increased risk for major bleeding. We used bivariate and multivariable logistic regression to explore the risk factors associated with major bleeding. Results During the study period, 1965 patients were enrolled. Of them, 1347 (69%) received intermediate‐ and 618 (31%) therapeutic‐dose anticoagulation, with a median duration of 12 days in both groups. During the hospital stay, 112 patients (5.7%) developed major bleeding and 132 (6.7%) had non‐major bleeding. The 30‐day all‐cause mortality rate for major bleeding was 45% (95% confidence interval [CI]: 36%‐54%) and for non‐major bleeding 32% (95% CI: 24%‐40%). Multivariable analysis showed increased risk for in‐hospital major bleeding associated with D‐dimer levels >10 times the upper normal range (hazard ratio [HR], 2.23; 95% CI, 1.38–3.59), ferritin levels >500 ng/ml (HR, 2.01; 95% CI, 1.02–3.95), critical illness (HR, 1.91; 95% CI, 1.14–3.18), and therapeutic‐intensity anticoagulation (HR, 1.43; 95% CI, 1.01–1.97). Conclusions Among patients hospitalized with COVID‐19 receiving intermediate‐ or therapeutic‐intensity anticoagulation, a major bleeding event occurred in 5.7%. Use of therapeutic‐intensity anticoagulation, critical illness, and elevated D‐dimer or ferritin levels at admission were associated with increased risk for major bleeding.

In recent years, the role of left ventricular ejection fraction (EF) as the gold standard parameter for the evaluation of systolic function has been questioned, and many efforts have been concentrated in the clinical validation of new noninvasive tools for the study of myocardial contractility. Improvement in the accuracy of speckle-tracking echocardiography has resulted in a large amount of research showing the ability of two-dimensional strain to overcome EF limitations in the majority of primary and secondary heart diseases. Currently, global longitudinal strain (GLS) is considered the most accurate and sensitive parameter for the assessment of early left ventricular dysfunction. This review summarizes the advantages that this measurement can provide in several clinical settings. Moreover, the important cautions that should be considered in making the choice to use GLS also are addressed. Finally, a special focus on bull's-eye polar maps for the assessment of regional changes of longitudinal function and the usefulness of these maps in the differential diagnosis of several diseases is provided.
