BACKGROUND Cardiac complications are among the most serious problems of thalassemia intermedia patients. The current study was initiated to address the latter issue through the study of the echocardiographic findings and correlate it with clinical characteristics of thalassemia intermedia patients in Duhok, Kurdistan region, Iraq. METHODS An echocardiographic assessment of 61 beta-thalassemia...
BACKGROUND The prevalence of pulmonary hypertension in adults with sickle cell disease, the mechanism of its development, and its prospective prognostic significance are unknown. METHODS We performed Doppler echocardiographic assessments of pulmonary-artery systolic pressure in 195 consecutive patients (82 men and 113 women; mean [+/-SD] age, 36+/-12 years). Pulmonary hypertension was prospec...
conclusions the etiology of pah in thalassemia is multifactorial such as inflammatory mediators. also, the absence of the spleen plays an important role in developing a high trv and pah. results average age of the patients was 21.15 ± 6.68 years. no significant difference was observed in the pap between the 2 groups of thalassemia major and intermedia and also the 2 sex groups. indeed, 6.6% of ...
Another point with regard to the PASP measurement of the patients in this study was made of tricuspid regurgitant jet. At the same time, the mean tricuspid regurgitant jet velocity was 1.7 ± 0.5 m/s in the patient population. When this value was analyzed, it gave the impression that sufficient flow was not obtained over the tricuspid valve. For this reason, since guidelines recommend to use con...
OBJECTIVE To determine the ability of conventional and Doppler echocardiography to distinguish between minor, acute massive, and subacute massive pulmonary embolism in patients with confirmed pulmonary embolism. DESIGN Prospective study of a consecutive series of 47 patients with confirmed pulmonary embolism. SETTING Department of internal medicine, university clinic. PATIENTS 11 patients...
RATIONALE Steady-state mild pulmonary hypertension is a risk factor for death in adults with sickle cell disease. Acute pulmonary hypertension has been reported during exercise and vasoocclusive pain crisis in these patients. OBJECTIVES The aim of the present study was to evaluate changes in pulmonary pressures and cardiac biomarkers during severe acute chest syndrome and their associations w...
