Of these, mitral stenosis (MS) is the primary lesion among all presentations, and rheumatic heart disease (RHD) is more prevalent in underdeveloped countries. Objective: To assess the magnitude of cardiovascular diseases and associated factors among pregnant women who had antenatal care follow-ups at selected tertiary hospitals in Addis Ababa, Ethiopia. Material and Methods: an institution-based cross-sectional study design was conducted in selected two tertiary hospitals located in Addis Ababa, Ethiopia. All pregnant women attending antenatal follow-up unit in the selected study setting w enrolled. The sample size for the study was determined by using the single population proportion formula. A pre-test was done in 5% of the samples at different hospitals from the study setting, and appropriate corrections was made to the data collection tool accordingly. Both primary (face to face interview) and secondary data (chart review) was done to collect the data. Result: A total of 215 pregnant women were included (response rate: 95.5%) and 26% were identified with cardiovascular disease. Significant factors associated with cardiovascular disease include primary education or read and write (AOR=1.48; 95% CI:1.33-1.66), urban residence (AOR=1.78; 95% CI:1.63-1.95), anemia during pregnancy (AOR=28.5; 95% CI:4.85-.215), family history of hypertension (p <0.001). gravidity and coffee consumption also showed strong statistically significant association with cardiovascular disease (p < 0.001). Conclusion & recommendation: Comparing the findings of this study with previous literature from Ethiopia, Sub-Saharan Africa, and worldwide revealed both consistencies and disparities in maternal health profiles and risk factors. Policy makers and program planners in Ethiopia should prioritize maternal health initiatives that address the multifaceted determinants of maternal health identified in this study.enCardiovascular diseasespregnancyelectrocardiographyechocardiographyEthiopiaThesis
