Echocardiographic findings in patients with acute pulmonary embolism at Sohag University Hospitals.

Background: Acute pulmonary thromboembolism (PTE) is one of the serious medical issues with higher prevalence and mortality rates. As mentioned in several medical reports, most of the chest pain patients, visiting the emergency departments, are usually diagnosed with either acute PTE, acute coronary syndromes, or acute aortic syndromes. The current study aimed to study the risk factors and explore the echocardiographic findings in patients with PTE.

Angiotensin converting enzyme DD genotype is associated with development of rheumatic heart disease in Egyptian children.

Angiotensin converting enzyme (ACE) gene polymorphism was previously studied in some cardiovascular diseases. There are only few studies which investigated this polymorphism in patients with rheumatic heart disease (RHD). The results of these investigations are inconsistent.

Lack of association between endothelial constitutive nitric oxide synthase (ecNOS 4 b/a) gene polymorphism and rheumatic heart disease.

Our aim in this work was to explore any possible association between ecNOS 4 b/a polymorphism and rheumatic heart disease (RHD). In this study, leukocyte DNA was extracted from 139 patients with RHD and 79 healthy control children. After amplification by PCR, the products were separated by electrophoresis in 6% polyacrylamide gel and visualized after ethidium bromide staining with UV light.
