Abstract OBJECTIVE: To identify case fatality rates and predictors of stroke in a private clinic in Kinshasa, Democratic Republic of Congo. METHODS: Two hundred and twelve black Africans were consecutively admitted to a clinic and prospectively assessed during the first 30 days by CT scan-proven stroke types and outcome. Univariate and multivariate analyses were used to estimate the in-hospital mortality risk for the following baseline characteristics: age, gender, education, arterial hypertension, diabetes, stroke types, leukocyte count, and haematocrit, blood glucose, uric acid, fibrinogen and total cholesterol levels. RESULTS: Haemorrhagic and ischaemic strokes were present in 52 and 48\% of the study population, respectively; and 44\% of all stroke type patients, 29\% of haemorrhagic stroke and 31\% of ischaemic stroke patients died. Compared to the survivors, deceased patients were significantly (p < 0.001) older with higher leukocyte counts and haematocrit, haemoglobin and fibrinogen levels, but lower glycaemic levels. The variable significantly associated with all stroke type mortalities in the multivariate model was ischaemic stroke (HR = 4.28, p < 0.001). The univariate risk factors of mortality in patients with ischaemic stroke were higher fibrinogenaemia (RR = 6.4; 95\% CI = 4.8-8.2 for tertile 3 and RR = 12.9; 95\% CI = 7.8-18.4 for tertile 4; p < 0.001) and higher glycaemia (RR = 3.3; 95\% CI = 1.4-5.7 for tertile 3 and RR = 6.7; 95\% CI = 5.2-9.2 for tertile 4; p < 0.001). CONCLUSION: We have shown that all acute stroke types remain a deadly nosological entity, and ischaemic stroke, baseline haematocrit and fibrinogen levels, and dependency on others' care were significantly associated with all stroke mortalities. Moreover, hyperfibrinogaemia and hyperglycaemia were the significant predictors of case fatality in ischaemic stroke patients. In Africa, the top priority for resource allocation for stroke services should go to the primary prevention of stroke.
