Key Points
- Assess in-hospital mortality rates and identify independent clinical predictors of death among patients hospitalized for hypertension-related complications.
- Enrolled 401 consecutive patients (mean age 54.3 years; 129 women) admitted for hypertension-related disorders at two hospitals in Mbuji Mayi, Congo.
- Recorded admission blood pressure, anthropometrics, cardiovascular risk factors, and hypertension awareness/treatment status, evaluating mortality predictors using stepwise logistic regression.
- In-hospital mortality was 22.2% (89 deaths) over a median stay of 15 days, with mean admission blood pressure reaching 178/106 mm Hg and 44.5% of aware patients receiving no prior treatment.
- Risk of death increased with systolic blood pressure (OR 1.43 per +10 mm Hg, 95% CI 1.15–1.77, P < 0.01), body mass index (OR 2.40 per +5 kg/m², 95% CI 1.39–4.17, P < 0.01), awareness versus unawareness (OR 3.17, 95% CI 1.52–6.61, P < 0.01), and lack of treatment (OR 2.33, 95% CI 1.12–4.76, P < 0.05).
- Mortality decreased with older age (OR 0.65 per +10 years, 95% CI 0.46–0.92, P < 0.05) and higher creatinine clearance (OR 0.71 per +10 ml/min/1.73 m², 95% CI 0.61–0.82, P < 0.001).

OOutcomeIn-hospital mortalityhard clinical
In-hospital mortality for hypertension-related admissions in Congo is exceedingly high (>20%), driven by elevated blood pressure, higher BMI, and lack of treatment.
