    Introduction: The aim of the study was to investigate the occurrence, the aetiology and the management of congestive heart failure in the cardiac centre of the St. Elizabeth catholic general hospital Shisong in Cameroon. Methods: Between November 2002 and November 2008, a population of 8121 patients was consulted in the referral cardiac centre of St. Elizabeth Catholic General Hospital. Of these patients, 462 were diagnosed with congestive heart failure according to the modified Framingham criteria for the diagnosis of heart failure. Complementary investigations used to confirm and establish the aetiology of the disease were the chest X-ray, electrocardiography, bi-dimensional Doppler echocardiography. Results: The results showed that the occurrence of congestive heart failure in our centre was 5.7%. Congestive heart failure was diagnosed in 198 females and 264 males, aged between 8 and 86 years old (42.5±18 years old). Post rheumatic valvulopathies (14.6%) and congenital heart diseases (1.9%) were the first aetiologic factor of congestive heart failure in the young, meanwhile cardiomyopathies (8.3%) in elderly followed by hypertensive cardiomyopathy (4.4%). Congestive heart failure was also seen in adults with congenital heart diseases in 0.01%. In this zone of Cameroon, we discovered that HIV cardiomyopathy (1.6%) and Cor pulmonale (8%) were represented, aetiological factors not mentioned in previous studies conducted in urban areas of Cameroon. The mean duration of hospital stay for the compensation treatment was thirteen days, ranging between 7 and 21 days), the mortality being 9.2%. All the medications recommended for the treatment of congestive heart failure are available in our centre but many patients are not compliant to the therapy or cannot afford them. Financial limitation is causing the exacerbation of the disease and premature death. Conclusion: Our data show a high incidence of congestive heart failure mainly due to post rheumatic valvulopathies in young patients in our centre. National program to fight against rheumatic fever and complications are of great urgency in our country. The compensation treatment of congestive heart failure is challenging in our milieu, characterized by poor compliance and financial limitations.Key words: Congestive heart failure, cardiac centre Shisong, valvulopathies, cardiomyopathy, Cameroon, Hypertension, heart failur

    AimTo determine clinical characteristics and mode of treatment of patients with heart failure in Yaounde military hospital (YMH).MethodsData of patients with heart failure (HF) followed on a period of 6 months in YMH were used to determine clinical characteristics and mode of treatment.ResultsA total of 72 patients were consecutively studied comprising 45 men (62.5%) and 27 women (37.5%) aged 62.8±16.5 and 61.1±19.4 years, respectively. All the patients presented with NYHA functional class III or IV. Alcohol was the most common etiological factor of HF (66.7%) hypertension was the most common risk factor for HF (37.5%) while only 16.7% of the patients were smokers. Global heart failure was the common presentation (60.9%). Left bundle branch was present in 47% of electrocardiograms while 8.7% of the patients were in atrial fibrillation. Dilated cardiomyopathy was the common lesion (80%). Most patients presented with severe left ventricular (LV) systolic dysfunction (66.6%). Male subjects had worse LV systolic dys-function compare to women without significant difference (56.3% vs 43.8% p=0.8). Diabete was not associated with severe LV dysfunction (78.9% on non diabetic vs 6.3% of diabetic patients). Current recommended pharmacology therapies were used in most of the cases. Diuretics were used in 100% while ACE inhibitors were in 91.3% of cases. 52.4% of patients had beta blockers.ConclusionMost heart failure patients in Cameroon present in the sixth decade with severe heart failure. All the recommended therapies are not available in our country

    Efficiency of an intervention package for arterial hypertension comprising telemanagement in a Cameroonian rural setting: The TELEMED-CAM study

    Introduction: Sub-Saharan Africa has a disproportionate burden of disease and an extreme shortage of health workforce. Therefore, adequate care for emerging chronic diseases can be very challenging. We implemented and evaluated the effectiveness of an intervention package comprising telecare as a mean for improving the outcomes of care for hypertension in Rural Sub-Saharan Africa. Methods: The study involved a telemedicine center based at the Yaounde General Hospital (5 cardiologists) in the Capital city of Cameroon, and 30 remote rural health centers within the vicinity of Yaoundé (20 centers (103 patients) in the usual care group, and 10 centers (165 patients) in the intervention groups). The total duration of the intervention was 24 weeks. Results: Participants in the intervention group had higher baseline systolic (SBP) and diastolic (DBP) blood pressure, and included fewer individuals with diabetes than those in the usual care group (all p<0.01). Otherwise, the baseline profile was mostly similar between the two groups. During follow-up, more participants in the intervention groups achieved optimal BP control, driven primarily by greater improvement of BP control among High risk participants (hypertension stage III) in the intervention group. Conclusion: An intervention package comprising tele-support to general practitioners and nurses is effective in improving the management and outcome of care for hypertension in rural underserved populations. This can potentially help in addressing the shortage of trained health workforce for chronic disease management in some settings. However context-specific approaches and cost-effectiveness data are needed to improve the application of telemedicine for chronic disease management in resource-limited settings.Key words: Hypertension, control, telemedicine, Cameroon, sub-saharan Afric

    Socio-demographic and epidemiological consideration of Africa’s COVID-19 response: what is the possible pandemic course?

    Many predicted a heavy toll of the COVID-19 pandemic on Africa. Its weakened health systems were harbingers of a terrible outcome. However, local expertise gathered from previous outbreaks and centralized public-health infrastructure with a clear action plan, in addition to a favorable demographic structure and climate, have put many countries in the continent in good standing to face this epidemic head on

    Endomyocardial Fibrosis: Still a Mystery after 60 Years

    The pathologist Jack N. P. Davies identified endomyocardial fibrosis in Uganda in 1947. Since that time, reports of this restrictive cardiomyopathy have come from other parts of tropical Africa, South Asia, and South America. In Kampala, the disease accounts for 20% of heart disease patients referred for echocardiography. We conducted a systematic review of research on the epidemiology and etiology of endomyocardial fibrosis. We relied primarily on articles in the MEDLINE database with either “endomyocardial fibrosis” or “endomyocardial sclerosis” in the title. The volume of publications on endomyocardial fibrosis has declined since the 1980s. Despite several hypotheses regarding cause, no account of the etiology of this disease has yet fully explained its unique geographical distribution

    Aims Raised blood pressure (BP) is the biggest contributor to mortality and disease burden worldwide and fewer than half of those with hypertension are aware of it. May Measurement Month (MMM) is a global campaign set up in 2017, to raise awareness of high BP and as a pragmatic solution to a lack of formal screening worldwide. The 2018 campaign was expanded, aiming to include more participants and countries. Methods and results Eighty-nine countries participated in MMM 2018. Volunteers (≄18 years) were recruited through opportunistic sampling at a variety of screening sites. Each participant had three BP measurements and completed a questionnaire on demographic, lifestyle, and environmental factors. Hypertension was defined as a systolic BP ≄140 mmHg or diastolic BP ≄90 mmHg, or taking antihypertensive medication. In total, 74.9% of screenees provided three BP readings. Multiple imputation using chained equations was used to impute missing readings. 1 504 963 individuals (mean age 45.3 years; 52.4% female) were screened. After multiple imputation, 502 079 (33.4%) individuals had hypertension, of whom 59.5% were aware of their diagnosis and 55.3% were taking antihypertensive medication. Of those on medication, 60.0% were controlled and of all hypertensives, 33.2% were controlled. We detected 224 285 individuals with untreated hypertension and 111 214 individuals with inadequately treated (systolic BP ≄ 140 mmHg or diastolic BP ≄ 90 mmHg) hypertension. Conclusion May Measurement Month expanded significantly compared with 2017, including more participants in more countries. The campaign identified over 335 000 adults with untreated or inadequately treated hypertension. In the absence of systematic screening programmes, MMM was effective at raising awareness at least among these individuals at risk
