Two-dimensional strain (2DS) is a novel method to measure strain from standard two-dimensional echocardiographic images by speckle tracking, which is less angle dependent and more reproducible than conventional Doppler-derived strain. The objective of our study was to characterize global and regional function abnormalities using 2DS and strain rate analysis in patients (pts) with pathological left ventricular hypertrophy (LVH) caused by non-obstructive hypertrophic cardiomyopathy (HCM), in top level athletes, and in healthy controls. The hypothetical question was, if 2DS might be useful as additional tool in differentiating between pathologic and physiologic hypertrophy in top-level athletes. We consecutively studied 53 subjects, 15 pts with hypertrophic cardiomyopathy (HCM), 20 competitive top-level athletes, and a control group of 18 sedentary normal subjects by standard echocardiography according to ASE guidelines. Global longitudinal strain (GLS) and regional peak systolic strain (PSS) was assessed by 2DS in the apical four-chamber-view using a dedicated software. All components of strain were significantly reduced in pts with HCM (GLS: -8.1 ± 3.8%; P < 0.001) when compared with athletes (-15.2 ± 3.6%) and control subjects (-16.0 ± 2.8%). In general, there was no significant difference between the strain values of the athletes and the control group, but in some of the segments, the strain values of the control group were significantly higher than those in the athletes. A cut-off value of GLS less than -10% for the diagnosis of pathologic hypertrophy (HCM) resulted in a sensitivity of 80.0% and a specificity of 95.0%. The combination of TDI (averaged S', E') and 2DS (GLS) cut-off values for the detection of pathologic LVH in HCM demonstrated a sensitivity of 100%, and a specificity of 95%. Two-dimensional strain is a new simple and rapid method to measure GLS and PSS as components of systolic strain. This technique could offer a unique approach to quantify global as well as regional systolic dysfunction, and might be used as new additional tool for the differentiation between physiologic and pathologic LVH.

The results may indicate the enormous potential of EMS for the treatment of patients within the cardiologic arena, especially those with CHF.

Sports cardiology is a new and rapidly evolving subspecialty. It aims to elucidate the cardiovascular effects of regular exercise and delineate its benefits and risks, so that safe guidance can be provided to all individuals engaging in sports and/or physical activity in order to attain the maximum potential benefit at the lowest possible risk. The European Society of Cardiology (ESC) advocates systematic preparticipation cardiovascular screening in an effort to identify competitive athletes at risk of exercise-related cardiovascular events and sudden cardiac death. However, the implementation of preparticipation screening is hindered because of lack of structured training and as a result lack of sufficient expertise in the field of sports cardiology. In 2008 the European Society of Cardiology published a core curriculum for the general cardiologist, in which sports cardiology was incorporated within the topic 'Rehabilitation and Exercise Physiology'. However, the exponential rise in knowledge and the growing demand for expertise in the field of sports cardiology dictates the need to systematically structure the knowledge base of sports cardiology into a detailed curriculum. We envisage that the curriculum would facilitate more uniform training and guideline implementation throughout Europe, and safeguard that evaluation and guidance of competitive athletes or individuals who wish to engage in leisure-time sports activities is performed by physicians with expertise in the field. The current manuscript provides a comprehensive curriculum for sports cardiology, which may serve as a framework upon which universities and national and international health authorities will develop the training, evaluation and accreditation in sports cardiology.
