Official title: Subclinical Cardiovascular Changes in Patient With Non Alcoholic Fatty Liver Disease (Predictive Value of Speckle Tracking Echocardiography )

Status Not yet recruiting

Clinical Trial Summary

the goal of this study (observational study ) is to learn about the subclinical cardiovascular changes in patients with nonalcoholic fatty liver . the main questions it aims to answer are 1. the role of speckle tracking echocardiogram in detection of subclinical cardiovascular complication in NAFLD patients 2. the role of fibroscan in diagnosis of nonalcoholic fatty liver the participant will be examined by fibroscan and speckle tracking echocardiogram

Clinical Trial Description

The diagnosis of Non Alcoholic Fatty Liver Disease ( NAFLD) requires evidence of hepatic steatosis by either imaging or histology and the exclusion of secondary causes of hepatic fat accumulation such as use of medications e.g ( corticosteroids , amiodarone , methotrexate ) , hereditary disorders e.g ( Wilson's disease , alpha 1 antitrypsin deficiency ) or viral infections additionally daily alcoholic consumption mustn't exceed 30g for men and 20g for women 1 Nonalcoholic fatty liver disease is rising in prevalence along with levels of obesity and type 2 diabetes mellitus such that it is now the most common cause of chronic liver disease worldwide prevalence in general population is 25 to 30% but this rises to 70% in patients with obesity and type 2 diabetes mellitus. Fibroscan is an evidence based ,transient elastography instrument for noninvasive evaluation of liver steatosis and fibrosis There are various studies substantiating the use of fibroscan in NAFLD. In a study by Wong et al 246 patients underwent liver stiffness measurement by fibroscan , In a study carried out by Yoneda et al , AUROC for F1 , F2 , F3 , F4 fibrosis were 0.881, 0.876 , 0.914 and 0.997 , respectively. Musso et al showed that for nonalcoholic steatohepatitis (NASH) with advanced fibrosis, , sensitivity and specificity of fibroscan were 0.85, 0.90 , 0.97 and 0.94 . Another study from India by sarin et al showed similar efficacy of fibroscan in NAFLD in patients from Northern India4 Convincing evidence now substantiates a strong association between the presence and severity of ( NAFLD) and the risk of cardiomyopathy (mainly left ventricular dysfunction and hypertrophy , possibly leading to heart failure and arrhythmias 5 Speckle-tracking Echocardiography a non-invasive ultrasound imaging technique allows an objective and quantitative evaluation of global and regional myocardial function independently from the angle of insonation and cardiac translational movements based on an analysis of the spatial dislocation of speckles on routine 2 dimensional sonograms Because of its potential benefits in the measurement of left ventricular function along with other systolic and diastolic echocardiographic parameters of left ventricular function measurement this novel technique is used in this study to assess the relationship between NAFLD and subclinical myocardial dysfunction All participants will be subjected to full history and examination including : - Demographic data with special habits - Underlying comorbidity (Diabetes mellitus , Hypertension , Cardiovascular disease - Symptoms of NAFLD eg: fatigue , loss of appetite , weight loss , pale stool - Symptoms of cardiac dysfunction including eg : - heart failure ( shortness of breath , fatigue , swelling of the feet ankles ,legs , abdomen or neck veins ) - arrhythmia ( fluttering feelings in the chest [palpitations} ) - heart attack ( chest pain or discomfort upper back or neck pain , indigestion , heartburn , nausea or vomiting , extreme fatigue ,upper body discomfort , dizziness and shortness of breath ) - Therapeutic history eg : drugs causing NAFLD ( corticosteroids , antidepressants , antipsychotics ) antihypertensive drugs , drugs to control Diabetes mellitus , Antiarrhythmic & anti ischemic drugs - EXAMINATION : *vital signs ( blood pressure , pulse , temperature , respiratory rate ) * dyslipidemic signs * cardiovascular examination chest examination * lower limb pulsation - Laboratory investigation including: 1. liver function 2. lipid profile 3. HBA1C 4. Renal function 5. Erythrocyte sedimentation rate ( ESR) & C - Reactive protein test ( CRP) - Imaging including: 1. Fibroscan : It is a special non-invasive ultrasound technology that measures liver stiffness (hardness) and fatty changes in the liver 2. Ultrasonography 3. Conventional Echocardiography : It is an imaging technique that enables accurate assessment of cardiac structures and cardiac function 4. Speckle Tracking Echocardiography: - Study Scores including: 1. ASCVD risk score (Atherosclerotic cardiovascular disease ) 2. CHA2DS2-VASc score - Sample size Sample size was calculated using Epi-Info7 based on prevalence of NAFLD and its subclinical cardiovascular abnormalities , the minimum patients required for this study is 60 patient - statistical analysis : statistical analysis will be performed using SPSS statistics ( statistical package for the social sciences) version 20 (USA) , patient characteristics and outcomes will be reported using standard descriptive statistics : frequency (percentage ) for categorical variables and mean (SD) continuous variables . ;
