Abstract:
The objective of the study was to evaluate the blood flow among heart failure patients by using echocardiography.180 patients (62 female and 118 male) with heart failure sign were enrolled. Their ages ranged between (20 – 85) years. The study was conducted at Khartoum state in Echocardiography departments of Omdurman Military Hospital and Sudan Heart Center during the period from November 2014 to September 2017. Two-dimensional, M-mode and Doppler echocardiograms were recorded using ultrasound machine HDI 4000 scanner (Philips Medical Systems) equipped with a commercially available 3-13 MHz linear transducer with color and power Doppler capability.
The incidence of the heart failure was high among the age group mean 60.56 years that means the risk of heart failure increase with age. In view of the importance of Ejection fraction by using 2D echo, the results showed that mean EF 38.94%(mnimum15% –maximum 60%).The left ventricular ejection fraction volume represents that the maximum was 60% and this was normal value unless the patient had right side failure or diastolic dysfunction which is called heart failure with preserved left ventricular ejection fraction (PLVEF) or “diastolic” heart failure. The hypertension is predominant cause of heart failure in Sudan (36. 1%).The common finding of the study was left ventricular systolic dysfunction LVSD which represent about 121 patients 67.7%. This study found that the correlation is significant at the 0.01 level. between the left ventricular internal diastolic dimeter LVIDD, left ventricular internal systolic dimeter LVISD and ejection fraction EF equal -.376 (negative) inversely proportional.
MR was severe in 23 (12.8%), moderate in 29 (16.1%), mild in 69 (38.3%), trivial in 25 (13.9%), and absent in 28 (15.6%). The remaining was mitral stenosis. In addition, the severity of MR correlated with the severity of systolic dysfunction. Ejection fraction (EF) reduced with the severity of the MR. small color flow jets are seen in roughly 38% of study sample and therefore large color flow jets are seen in roughly 12.8% of study sample. The incidence of mild regurgitation tends to increase with age.
