Risk factors of Hemorrhagic Stroke- a Case-Control Study in Bangladesh

Background: Spontaneous intracerebral hemorrhage is one of the leading causes of mortality and morbidity. Genetic factors play an important role in this disease. Among the non-genetic causes Hypertension (HTN), IDDM (insulin dependent diabetes mellitus), NIDDM (non-insulin dependent diabetes mellitus), family history of hemorrhagic stroke, smoking, previous history of ischemic stroke, alcohol intake and education level are important. Methods: The aim of the study was to evaluate the association between ICH and non-genetic risk factors. This was a case-control study with 120 participants. The place of the study was in the Neurosurgery department of Sylhet Women’s Medical College Hospital (SWMCH) and the study period was 2 years. Result: Alcohol consumption (RR=3, Odd=3.11) showed highest risk for ICH. Other risk factors of ICH were smoking (RR=2, Odd=2.36), family history (F/H) of ICH (RR=1.3, Odd=1.38), Hypertension (RR=1.1, Odd=1.39) and below 12 class education status (RR=1.08, Odd=1.63). The relative risk of IDDM, NIDDM, previous history (P/H) of ischemic stroke were less than 1. Conclusion: There are few controllable risk factors of hemorrhagic stroke apart from genetic risk factors.
