Clinical, hemodynamic, electrocardiographic (ECG), echocardiographic, left ventricular (LV), and coronary angiographic (CA) findings are reported in a case with apical hypertrophy (AH), a form of hypertrophic nonobstructive cardiomyopathy (HNCM). The most striking symptom was chest pain and the most conspicuous electrocardiographic finding consisted of giant negative T waves, reaching an amplit...

BACKGROUND Data on the prognostic value of echocardiographic left ventricular (LV) hypertrophy (LVH) as defined by LV wall thickness rather than LV mass estimate are scarce and not univocal. Thus, we investigated the value of LV mass index, wall thickness, and relative wall thickness (RWT) in predicting cardiovascular events in the PAMELA population. METHODS At entry 1,716 subjects underwent ...

INTRODUCTION Physiological cardiac hypertrophy and dilation are common findings in heavy physical load activity. We carried out this study to investigate the relationship between construction work and cardiac parameters adaptations, by comparing healthy masons to office workers on heart ultrasound. METHODS The study was carried out on, 50 construction workers and 50 office workers matched for...

FIGURE 1. M-mode scan from aorta (Ao) to apex of left ventricle (LV) performed with uniform speed of transducer. Note length of narrowed left ventricular outflow tract (OT). IVS, interventricular septum; c, cusps of aortic valve; F, fluttering of mitral valve; LA, left atrium; aML and pML, anterior and posterior leaflets of mitral valve; IVS, interventricular septum; ppm, posteromedial papillar...

Yield reduction caused by late application of glyphosate to glyphosate-resistant cotton (Gossypium hirsutum; GRC) expressing CP4 5-enol-pyruvylshikmate-3-P synthase under the cauliflower mosaic virus-35S promoter has been attributed to male sterility. This study was aimed to elucidate the factors and mechanisms involved in this phenomenon. Western and tissue-print blots demonstrated a reduced e...

Ultrasonic backscatter of myocardial walls is directly related to the morphometrically evaluated collagen content in humans. The integrated backscatter is also increased in hypertrophic cardiomyopathy, whereas it gives normal values in the physiological hypertrophy of elite athletes. We assessed the quantitatively evaluated myocardial reflectivity in 46 mild to moderate, clinically uncomplicate...

BACKGROUND Experimental data demonstrated that inactivation of toll-like receptor (TLR) pathway components attenuated left ventricular (LV) remodeling induced by pressure overload. This study investigated the impact of TLR6 Ser249Pro polymorphism on LV structure in hypertensive subjects. METHODS A sample of 443 patients (266 women and 177 men) was evaluated by clinical history, physical exami...

STUDY DESIGN A cadaveric study. OBJECTIVE To investigate possible variations of posterior pharyngoesophageal (PE) wall thickness in the horizontal plane and their implications for anterior spine surgery. SUMMARY OF BACKGROUND DATA Lower cervical levels (C5-7) are most commonly involved in cases of PE injury, and PE wall thickness could be one of the proposed reasons for the high incidence o...

Brief coronary artery occlusion (CAO) and reperfusion induce myocardial stunning and late preconditioning. Postsystolic wall thickening (PSWT) also develops with CAO and reperfusion. However, the time course of PSWT during stunning and the regional function pattern of the preconditioned myocardium remain unknown. The goal of this study was to investigate the evolution of PSWT during myocardial ...
