History Heart failure with preserved ejection fraction (HFpEF) is a term used to describe patients who show symptoms of HF but have a normal or nearly normal left ventricular ejection fraction (LVEF). The purpose of this research was to examine the use of 2D-STE for the detection of right ventricular dysfunction in patients with heart failure who showed no sign of ejection fraction reduction. Topics and approaches: Both Benha University and the Benha Teaching Hospitals participated in the study's research. two hundred people participated, all of whom were split evenly between two groups: group I included 100 people who had been diagnosed with HFpEF, while group II included the other 100 people. Fifty healthy people of the same age and gender were matched up with the patients who served as the control group. Right ventricular diameter (RVD; mid, basal, longitudinal), Tricuspid annular plane systolic excursion (TAPSE; P = 0.473), and right ventricular fractional area change (RVFAC; P = 0.12) were not significantly different between the two groups. Patients with HFpEF who have characteristics detectable by 2D speckle tracking echocardiography have an increased likelihood of a poor prognosis, according to the study's authors. When compared to the findings of standard 2D echocardiography, this is a major difference. ConclusionsThese findings provide support to the concept that RV 2D-STE might be utilised to accurately diagnose people with HFpEF .
