Abstract P632: The Ballana Heart Study: Preliminary Results

Abstract

Introduction: There are considerable ethnic variations in the incidence and severity of cardiovascular diseases (CVD). To date, there have been very few studies from Africa and the MENA region and none that have focused on CVD. Ballana Heart Study (BHS) is a prospective cohort study of Egyptian Nubian population who live in the Ballana village (29,000 inhabitants) in the south of Egypt. Aim: Defining the cardiovascular phenotype, genotype and risk factors combined with follow-up visits for 30 years. Methods: Participants ≥18 years old after consenting go through a series of stations. A fasting venous blood sample is collected for diagnostic, genetic, molecular biomarkers testing and biobanking. Followed by a detailed questionnaire on demographic characteristics, anthropometry, vital signs, CVD risk factors and family history. Detailed clinical phenotyping including ECG, and Echocardiography. Follow-up visits and/or phone interviews occur every 1-3 years depending on their severity risk for a period of 30 years. Participants with evidence of CVD are referred to the Aswan Heart Centre for management. Results: A random sample of 1,200 representative households was obtained from official government bills. To date, 549 households were analyzed. The preliminary findings in the first 2000 participants showed a mean age of 46 years (62% females). The rates of consanguinity between spouses and parents were 45% and 39% respectively. Seventy percent were either obese or overweight (BMI ≥30 kg/m 2 .), 65% had LDL ≥ 100 mg/dL and 37% reported a family history of CVD. Investigation showed diabetes (23%), hypertension (20%), ischemic heart diseases (3.5%), only 15 patients (0.8%) had echocardiographic evidence of rheumatic heart disease (RHD) as defined by the world heart federation criteria and 7 patients (0.4%) were diagnosed with adult congenital heart disease. Conclusion: Population-based studies and community engagement have become an increasingly prevalent means of improving health. BHS is among the first population studies in Egypt and the MENA region to focus on CVD . BHS provides a phenotypically well-characterized population, the preliminary results has shown a very high incidence of consanguinity, obesity, diabetes, dyslipidemia and hypertension. Future research integration of OMICs data and other determinants of health is essential to advancements in precision medicine, CVD understanding and prevention. It is anticipated that this ongoing study will yield valuable information for formulating healthcare policy.
