Hemophilia usually presents as bleeding after minor trauma or as a spontaneous bleed due its hypocoagulable state. Hemophilia A represents 80-85% of the total hemophilia population with a prevalence of 1:10,000. Cardiovascular risk factors were common in the general population compared with hemophilia patients. This study aims to identify cardiovascular risk factors in adult Javanese patients with hemophilia A and their relationship with hemophilia severity. This cross-sectional study involved registered Javanese race male patients at Dr. Moewardi General Hospital from November 2019 - April 2020. There are 76 hemophilia A patients, after excluding patients with other comorbidities, non-Javanese race and age >18 years old, 33 appropriate patients were then randomized. The study group consists of 30 patients with hemophilia A and 30 non-hemophilia patients. Data were collected once during patient visits to the hospital polyclinic. The collected data were body mass index (BMI), blood pressure, fasting blood sugar (FBS), total cholesterol, and uric acid. They were analyzed using the Spearman rank test. Median values of BMI scores were 20.82 (13.67-41.52) kg/m² for hemophilia A group and 24.67 (9.38-53.32) kg/m² for the control group (p < 0.05). Further, median values of diastolic blood pressure, the median of FBS, and mean values of the uric acid level also showed a significant difference (p < 0.05). Otherwise, the mean values of systolic blood pressure and median values of total cholesterol showed no significant difference. The BMI score, diastolic blood pressure, fasting blood sugar, and uric acid appear to be significant cardiovascular risk factor profiles in Javanese adult patients with hemophilia A. Hence, there must be a consideration, screening, and treatment for the cardiovascular risk factors in hemophilia A patients. Although the other studies are not sufficient to show recommended therapeutic targets and the results of reducing cardiovascular risk factors in hemophilia patients.
