Relationship Between Blood Groups and Cardiovascular Diseases: Insights From an Algerian Inpatient Study

This study provides novel insights into the distribution of ABO and Rh blood types among Algerian patients with CVD, highlighting a prevalence of Group O and Rh-positive (Rh+) individuals, though without significant associations between blood groups and major cardiovascular risk factors. Contrary to previous findings suggesting elevated cardiovascular risk in non-O blood groups, our results did not establish significant associations between blood groups and cardiovascular conditions or risk factors. The high prevalence of ACS, hypertension (particularly among older males), dyslipidemia, and smoking underscore the urgent need for targeted preventive strategies and further research to elucidate the complex interplay between blood types, genetic factors, and CVD in this population. These findings emphasize the necessity for addressing modifiable risk factors through education and preventive measures to improve cardiovascular outcomes.
