Introduction:
Heart failure (HF) is a deadly, disabling and often
costly syndrome worldwide. Unfortunately, there is a paucity
of data describing its economic impact in sub-Saharan Africa;
a region in which the number of relatively younger cases will
inevitably rise.
Methods:
Heath economic data were extracted from a prospec-
tive HF registry in a tertiary hospital situated in Abeokuta,
south-west Nigeria. Out-patient and in-patient costs were
computed from a representative cohort of 239 HF cases includ-
ing personnel, diagnostic and treatment resources used for their
management over a 12-month period. Indirect costs were also
calculated. The annual cost per person was then calculated.
Results:
Mean age of the cohort was 58.0
±
15.1 years and
53.1% were men. The total computed cost of care for HF in
Abeokuta was 76 288 845 Nigerian Naira (US$508 595), trans-
lating to 319 200 Naira (US$2 128) per patient per year. The
total cost of in-patient care (46% of total healthcare expendi-
ture) was estimated at 34 996 477 Naira (about US$301 230).
This comprised 17 899 977 Naira (50.9%; US$114 600) and
17 806 500 Naira (49.1%; US$118 710) for direct and indirect
costs, respectively. Out-patient cost was estimated as 41 292 368
Naira (US$275282). The relatively high cost of out-patient care
was largely due to cost of transportation for monthly follow-
up visits. Payments were mostly made through out-of-pocket
spending.
Conclusion:
The economic burden of HF in Nigeria is particu-
larly high, considering the relatively young age of affected cases,
a minimum wage of 18 000 Naira (US$120) per month and a
considerable component of out-of-pocket spending for those
affected. Health reforms designed to mitigate the individual-to-
societal burden imposed by the syndrome are required.
CARDIOMETABOLIC RISK FACTORS IN AMBULATO-

ac.keIntroduction:
There is a rising burden of non-communicable
diseases (NCDs) in Africa as a result of a rise in risk factors
(RFs) due to the epidemiological transition. These conditions
are largely asymptomatic, especially early on. Contact with
patients with inter-current illnesses offers an opportunity for
opportunistic screening. However primary healthcare facilities
are usually overcrowded, understaffed and underequipped,
making screening difficult, hence a lost opportunity. We inves-
tigated the prevalence of selected RFs in ambulatory patients
attending primary healthcare facilities in Nairobi.
Methods:
Twenty-four public and private facilities registered in
Nairobi were randomly selected. Patients, 35 years and above on
their index visit to the facility for the particular complaint, were
eligible for recruitment. Every fifth eligible patient was recruited
until the target of 10 per facility. Following informed consent,
a history was taken for socio-demographic data, alcohol and
tobacco use, self-reported hypertension, diabetes and HIV
status, and drug history. Blood pressure, weight and height for
BMI, and waist and hip circumference were measured. Fasting
glucose, fasting lipid profile, serum creatinine for calculation
of eGFR and serum uric acid levels were assayed. Continuous
data are presented as means and categorical data as percent-
ages. Prevalence of RFs is presented as proportions with 95%
confidence intervals (CI). Correlations were done using the
chi-square test.
Results:
We studied 213 patients. Mean age was 45
±
9.4 years,
and 64.3% were female. The prevalence (CI) of the RFs in
the patients were as follows: smoking: 5.6% (2.9–96); obesity:
34.9% (28.5–41.7); diabetes: 8% (4.7–12.5), hypertension: 23.5%
(18–29.5), and dyslipidaemia: 73.7% (67.3–79.5); 16.3% (11–22)
had abnormal kidney function, 14.6% were in stage 2 and 1.4%
in stage 3 renal failure. Urinary albumin was not done so it was
not possible to identify stage 1 CKD. A total of 57% of hyper-
tensives and 63% of diabetics were newly recognised. There was
a statistically significant gender difference in smoking: male
14.5%, female 0.7% (
p
=
0.0001) and obesity: male 23.55%,
female 41.2% (
p
=
0.01)
Conclusions:
There was a high prevalence of cardiometabolic
RFs, most of it unrecognised, in attendees of primary health-
care facilities for routine care. This offers an opportunity for
opportunistic screening. Training of primary healthcare work-
ers and equipping the facilities to enable screening is an impor-
tant step in the control of NCDs.

Introduction:
Risk factors, co-morbidities and end-organ
damage in newly diagnosed hypertension are poorly described
in larger cohorts of urban African patients undergoing epide-
miological transition.
Methods:
We prospectively collected detailed clinical, biochemi-
cal and echocardiography data of all subjects with hypertension
