The GE Vivid E9 is the top-of-the-line premium cardiovascular ultrasound machine from GE. It has amazing image quality and the latest features including xMatrix and 4D cardiac. This makes cardiac evaluation more efficient, especially in stress echo exams. The E9 also includes Accelerated Volume Architecture, resulting in faster processing times and more patient data via increased volume size, resolution, and rate.
Background: High-risk patients with hypertrophic cardiomyopathy (HCM) are identified by contemporary risk stratification and effectively treated with implantable cardioverter-defibrillators (ICDs). However, long-term HCM clinical course after ICD therapy for ventricular tachyarrhythmias is incompletely understood. Methods and Results: Cohort of 486 high-risk HCM patients with ICDs was assembled from 8 international centers. Clinical course and device interventions were addressed, and survey questionnaires assessed patient anxiety level and psychological well-being related to ICD therapy.
Objective Current guidelines recommend precautionary disqualification from competitive sports in patients with hypertrophic cardiomyopathy (HCM). We assessed the incidence of cardiovascular events in a cohort of patients with HCM engaged in long-term exercise programmes and competitive sport. Methods We reviewed data on 88 consecutive athletes diagnosed with HCM, from 1997 to 2017; 92 male, 98 Caucasian, median age 31 (IQR: 19-44) years. All participated in regular exercise programmes and competitive sport at study entry. We performed follow-up evaluation after 7±5 (1-21) years.
Purpose: Interleukin (IL)-8 is a proinflammatory C-X-C chemokine involved in inflammation underling cardiac diseases, primary or in comorbid condition, such diabetic cardiomyopathy (DCM). The phosphodiesterase type 5 inhibitor sildenafil can ameliorate cardiac conditions by counteracting inflammation. The study aim is to evaluate the effect of sildenafil on serum IL-8 in DCM subjects vs. placebo, and on IL-8 release in human endothelial cells (Hfaec) and peripheral blood mononuclear cells (PBMC) under inflammatory stimuli.
