“…Few studies have investigated the effects on atrial volumes. Using echocardiography and cardiac magnetic resonance imaging (CMR), recent studies have shown increased atrial dimensions and volumes in endurance athletes (6)(7)(8). However, studies of atrial adaptation to training in women are scarce and data on the effects on right atrial volumes in both men and women is lacking.…”

“…22 The most frequently used quantification technique for LV volumetric analysis is ECG-gated, segmental balanced steady-state free precession cinegraphic imaging, which gives excellent blood-tissue differentiation without any contrast. 23,24 LV volumes are evaluated by applying the Simpson rule, using a series of shortacting images obtained with a slice thickness of 6-8 mm.…”

Ischemic heart disease morbidity and mortality are closely related to global and regional left ventricular function. The evaluation of left ventricular global function is a relevant part in the evolution of ischemic heart disease because it plays a significant role in prognosis prediction and patient management after revascularization. Regional function is also a critical part of the evolution, offering a possible and reliable mode for the assessment of myocardial disease. Currently several techniques for the evaluation of left ventricular parameters and function are in use. In this review we will discuss and compare currently available methods for the evaluation of global and regional left ventricular function such as 2D and 3D echocardiography, 3D speckle-tracking echocardiography, multi-slice computed tomography, and cardiac magnetic resonance imaging.Keywords: ischemic heart disease, echocardiography, 3D speckle-tracking echocardiography, multi-slice computed tomography, cardiac magnetic resonance imaging REVIEW DOI: 10.1515/jim-2017-0020 CARDIOLOGY // IMAGING Ischemic heart disease is the leading cause of death around the world. The morbidity and mortality rates are closely associated to regional and global left ventricular function in these patients. 1,2 The evaluation of global left ventricular (LV) function with noninvasive imaging tools has an important role in the therapeutic management and prognosis of patients with ischemic cardiac diseases. Several parameters have been proposed as illustrative for global left ventricular function such as volumes, ejection fraction, dimensions, end-diastolic pressure, contractility, and deformation parameters. Global systolic function is most often evaluated by measuring the difference in the end-diastolic and end-systolic volumes, determined in one, two and three dimensions, divided by the adequate end-diastolic volume. 3 Echocardiography is the most frequently used noninvasive technique for the analysis of LV parameters and function because of its accessibility, portability, and widely validated scale.

Recent studies have reported on an association between endurance sport, atrial enlargement and the development of lone atrial fibrillation in younger, male cohorts. The atrial morphology and function of middle-aged, physically-active males and females have not been well studied. We hypothesized that middle-aged males would demonstrate larger left atrium (LA) and right atrium (RA) volumes compared to females, but atrial function would not differ. LA and RA volume and function were evaluated at rest in healthy adults, using a standardized 3.0Tesla cardiac magnetic resonance protocol. Physical activity, medical history, and maximal oxygen consumption ( _ VO 2peak ) were also assessed. Physically-active, middle-aged men (n = 60; 54 ± 5 years old) and women (n = 30; 54 ± 5 years old) completed this study. Males had a higher body mass index, systolic blood pressure, and _ VO 2peak than females (p < .05 for all), despite similar reported physical activity levels. Absolute and BSA and heightindexed LA and RA maximum volumes were higher in males relative to females, despite no differences in ejection fractions (p < .05 for all). In multivariable regression, male sex p < .001) and _ VO 2peak (p = .004) were predictors of LA volume (model R 2 = 0.252), whereas _ VO 2peak (p < .001), male sex (p = .03), and RV EF (p < .05) were predictors of RA volume (model R 2 = 0.377). While middle-aged males exhibited larger atrial volumes relative to females, larger, prospective studies are needed to explore the magnitude of physiologic atrial remodeling and functional adaptations in relation to phenotypic factors.
