Predictors of rehospitalization in patients admitted with heart failure in Abeokuta, Nigeria: data from the Abeokuta heart failure registry.

OBJECTIVE: We sought, for the first time, to examine the rate and predictors of hospital readmission in patients discharged after an episode of heart failure (HF) in Nigeria. METHODS: This was a hospital-based, prospective, observational study that used the data from the Abeokuta HF Registry. RESULTS: Overall, 1.53% (95% confidence interval [CI] 0.58-4.02) and 12.2% (95% CI 8.88-16.8) of patients were re-hospitalized at least once within 30 days and 6 months, respectively (5.3% had multiple readmissions); the latter comprised 21/138 men (15.2%) and 11/124 (8.9%) women. A total of 11 (4.2%) died (all of whom had been rehospitalized). Worsening HF (24 cases, 75%) was the commonest reason for readmission. Among others, factors associated with rehospitalization included presence of mitral regurgitation (odds ratio [OR] 2.37, 95% CI 1.26-4.46), age ≥ 60 years (OR 2.04, 95% CI 0.96-3.29), presence of tricuspid regurgitation (OR 1.77, 95% CI 0.86-3.61), and presence of atrial fibrillation (OR 1.34, 95% CI 0.59-3.03). However, on an adjusted basis, only female sex (adjusted OR 0.33, 95% CI 0.14-0.79; P = .014 vs male) and body mass index <19 kg/m² (adjusted OR 3.74, 95% CI 1.15-12.16; P = .028 vs ≥ 19 kg/m²) were independent correlates of readmission during 6 months' follow-up. CONCLUSIONS: HF rehospitalization within 6 months' follow-up occurred in ∼12% of our cohort living an environment where HF etiology is predominately nonischemic and the HF population is relatively younger. Higher rates of readmission were noted in those with older age, lower body mass index, low literacy, lower serum sodium level, and presence of atrial fibrillation, renal dysfunction, and valvular dysfunction.

Short-term outcomes after hospital discharge in patients admitted with heart failure in Abeokuta, Nigeria: data from the Abeokuta Heart Failure Registry.

BACKGROUND: Compared to other regions of the world, there is a paucity of data on the short-term outcome of acute heart failure (AHF) in Africa's most populous country, Nigeria. We examined the six-month outcomes (including case fatalities) in 285 of 309 AHF subjects admitted with HF to a tertiary hospital in Abeokuta, Nigeria. METHODS: The study cohort of 285 subjects comprised 150 men (52.6%) and 135 women (47.4%) with a mean age of 56.3 ± 15.6 years and the majority in NYHA class III (75%). RESULTS: There were a number of differences according to the subject's gender; men being older and more likely to present with hypertensive heart disease (with greater left ventricular mass) while also having greater systolic dysfunction. Mean length of stay was 10.5 ± 5.9 days. Mean follow up was 205 days, with 23 deaths and 20 lost to follow up. At 30 days, 4.2% (95% CI: 2.4-7.3%) had died and by 180 days this had increased to 7.5% (95% CI: 4.7-11.2%); with those subjects with pericardial disease demonstrating the highest initial mortality rate. Over the same period, 13.9% of the cohort was re-admitted at least once. CONCLUSIONS: The characteristics of this AHF cohort in Nigeria were different from those reported in high-income countries. Cases were relatively younger and presented with non-ischaemic aetiological risk factors for HF, especially hypertensive heart disease. Moreover, mortality and re-admission rates were relatively lower, suggesting region-specific strategies are required to improve health outcomes.

Contemporary profile of acute heart failure in Southern Nigeria: data from the Abeokuta Heart Failure Clinical Registry.

OBJECTIVES: The aim of this study was to determine the contemporary profile, clinical characteristics, and intrahospital outcomes of acute heart failure (AHF) in an African urban community. BACKGROUND: There are limited data on the current burden and characteristics of AHF in Nigerian Africans. METHODS: Comprehensive and detailed clinical and sociodemographic data were prospectively collected from 452 consecutive patients presenting with AHF to the only tertiary hospital in Abeokuta, Nigeria (population about 1 million) over a 2-year period. RESULTS: The mean age was 56.6 ± 15.3 years (57.3 ± 13.4 years for men, 55.7 ± 17.1 years for women), and 204 patients (45.1%) were women. Overall, 415 subjects (91.8%) presented with de novo AHF. The most common risk factor for heart failure was hypertension (pre-existing in 64.3% of patients). Type 2 diabetes mellitus was present in 41 patients (10.0%). Hypertensive heart failure was the most common etiological cause of heart failure, responsible for 78.5% of cases. Dilated cardiomyopathy (7.5%), cor pulmonale (4.4%), pericardial disease (3.3%), rheumatic heart disease (2.4%), and ischemic heart disease were less common (0.4%) causes. The majority of subjects (71.2%) presented with left ventricular dysfunction (mean left ventricular ejection fraction 43.9 ± 9.0%), with valvular dysfunction and abnormal left ventricular geometry frequently documented. The mean duration of hospital stay was 11.4 ± 9.1 days, and intrahospital mortality was 3.8%. CONCLUSIONS: Compared with those in high-income countries, patients presenting with AHF in Abeokuta, Nigeria, are relatively younger and still of working age. It is also more common in men and associated with severe symptoms because of late presentation. Intrahospital mortality is similar to that in other parts of the world.

Neuropsychiatric and parkinsonian manifestations of dementia: a case report in a Nigerian woman.

Neuropsychiatric manifestations sometimes referred to as behavioral and psychological symptoms (BPSD) are not uncommon in dementias, especially in moderate-to-severe cases. When these symptoms occur in the setting of Parkinsonism, fluctuating cognition, visual hallucinations and neuroleptic sensitivity, then the most likely diagnosis is dementia with Lewy bodies (DLB). Although this type of dementia is not infrequently encountered in primary care, it may be missed because of its tricky modes of presentation. We report a clinically diagnosed DLB in a 67-year-old Nigerian female to raise awareness among primary care and mental health practitioners in order to enhance better detection and treatment, especially in the setting of a developing economy.
