Evaluation of Subclinical Systolic Dysfunction in Patient with Grade 1 Diastolic Dysfunction

Abstract

background: Recent epidemiological studies have demonstrated that nearly half of allpatients with heart failure (HF) have preserved left ventricular ejection fraction(HFPEF). Thereby it is mandatory to include other hemodynamic indices in the traditional evaluation of the systolic function of the heart beside the EF.Aim of the study was to assess the occurrence of subclinical systolic dysfunction in hypertensive patients with diastolic dysfunction referred for echocardiograph assessment of left ventricular function in a hospital.Methods: 30 patients were recruited from the Echocardiography lab. The analysis of diastolic dysfunction was based on the E/A ratio using PW- Doppler echocardiogram. measurement of EF and SV by measuring end systolic and end diastolic dimensions of left ventricle by M-Mode guided 2D echocardiogram. Measurement of HR from ECG. calculation of SI. CO and CI were done.Results & Discussion: The percentages of parameters which were found below normal levels are as follow: SV: 33.3% (10 out of 30 patients). SI : 40%(12 out of 30 patients). CO: 20%(6 out of 30 patients) and CI:53.3%(16 out of 30 patients).Conclusion : EF is not enough in evaluation subclinical systolic impairment in HT patient , CI should be used in concomitant with EF in traditional evaluation of any patient with suspicion of HF.
