Introduction Stroke is one of the most common causes of morbidity and mortality worldwide. Around 50-85 percent of strokes are due to ischemic cerebral infarction and 7-27 percent to intra-cerebral haemorrhage. Since the incidence of stroke is increasing in our country, the study aims to identify various factors associated with stroke and to assess the mortality in acute stroke patient within five days of admission.Materials and Methods:This was a retro-spective analysis of data on study of 100 newly diagnosed stroke patients admitted in Neurology unit of a tertiary hospital over a period of one year. Approval for the study was taken from the IRB of the hospital prior to data collection. For data collection, a proforma was filled for each newly diagnosed stroke patient after informed consent from patient or his/her guardian with follow-up and treatment in the hospital. Patient were followed for mortality outcome (survival or death) up to five days in-hospital stay. Those stroke patients who had been already treated or presented to emergency room after 72 hours of stroke episode were excluded. The collected data were analysed using SPSS software.Results:Of all consecutive 100 stroke patients; the male to female ratio was 59:41 and the mean age was 63.13 years. Major risk factors found were hypertension, smoking, diabetes, heart diseases. The common presentations were weakness of limbs, dysphagia, impaired-consciousness, gaze disturbances, vomiting, sensory loss and deviation of mouth. Of the 100 stroke patients 44 (44%) were ischaemic and 56 (56%) were haemorrhagic. Among the ischaemic one (2.27%) patient and among haemorrhagic 12 (21.4%) patient died in the hospital. The overall mortality rate was 13% among stroke patients.Conclusion:This study showed 13% overall five days in-hospital mortality in new stroke patients. Mortality among haemorrhagic stroke patients is higher than ischaemic ones.
