BackgroundEarly diagnosis and adequate treatment of Group A streptococcal throat infection is an important initial stage in the primary prevention of acute rheumatic fever and rheumatic heart disease. This preventable condition associated with high mortality rates mandates a thorough understanding by the general public and the health.ObjectiveThe aim of the study was to assess the level of awareness about different aspects of rheumatic heart disease in patients coming to the outpatient department of the Buea regional Hospital, South West region of Cameroon.MethodsThis was a cross-sectional descriptive study carried in the outpatient department of the Buea Regional Hospital, Cameroon. The study population was adults and children aged 9 years and above. Data collection was done by using a self-administered questionnaire addressed to assess awareness on rheumatic heart disease.ResultsA total of 256 participants were interviewed, of which 70 (27.3%) were males. Their mean age was 34.4 ± 11.9 years (males: 36.2 ± 12.7 years versus females: 33.7 ± 11.6 years, p = 0.129). Most of the participants were in the 20 to 29 year old group (37.9%). More than two thirds (71.1%) of the participants reported having had sore throat at least once. The disease was treated with antibiotics in only 45.4%, with the treatment prescribed by a health care professional in 35.8% of the cases. About 73% of the respondents did not know what causes sore throat, and most (71.1%) were unaware of any complications that could arise from poorly treated sore throat. More than 70% of the participants did not know that sore throat can be associated with heart disease. Rheumatic heart disease was unknown to 82% of the participants and 95% of them did not know what causes RHD. Only 5.1% percent of the participants had an adequate knowledge of RHD. Age ≤ 35 years, post-secondary level of education, and having heard of RHD were significantly associated with an adequate knowledge. After adjusting for age, post-secondary education (aOR: 9, [95% C: 1.2–67.5], p = 0.019), and having heard of RHD (aOR: 18.1, [95% CI: 4.7–70.3], p<0.001) were still associated with a fair knowledge.ConclusionsLevels of knowledge and awareness on rheumatic heart disease is low. This study provides important insight into the perception and practices related to sore throat that can be used in the design of awareness activities aimed reducing the risk of RHD in Cameroon. The appropriateness of antibiotics prescribed, and the health care provider awareness and knowledge levels regarding RHD in Cameroon has not been reported yet in the literature. This grey area deserves more research.

ObjectiveThe pattern of heart disease is diverse within and among world regions. The little data on the spectrum of heart disease in Cameroon has been so far limited to major cities. We sought to describe the pattern of heart disease in Buea, the South West Region of Cameroon, a semi-urban setting. This was a descriptive cross-sectional study. Between June 2016 and April 2017 the echocardiography register of the Buea Regional Hospital was surveyed. We extracted data on the age, sex and echocardiographic diagnosis.ResultsOut of 529 patients who underwent echocardiography, 239 (45.2%) had a definite heart disease. There were 137 (57.3%) females. The mean age was 58 years (range 3–94 years). The most common echocardiographic diagnoses were hypertensive heart disease (43.2%), dilated cardiomyopathies (17.6%), ischemic heart diseases (9.6%), and cor pulmonale (8.8%). Rheumatic heart disease affected 6.7% of the patients. The most common rheumatic heart disease was mitral stenosis followed by mitral regurgitation. Congenital heart disease represented 2.1% and 5 patients (2.1%) had pulmonary hypertension. Hypertensive heart disease is the most common cardiac disease in this semi-urban region in Cameroon. Rheumatic heart disease still affects a sizable proportion of patients. Prevention of cardiac disease in our setting should focus on mass screening, the treatment and control of hypertension.

BackgroundSub-Saharan Africa (SSA) is experiencing an epidemic of cardiovascular diseases (CVD) as a result of a rapid epidemiological transition. Little is known about the admission for CVD and outcome in rural and semi-urban settings in Cameroon in this era of epidemiological transition. The aim of this study was to determine the frequency and the pattern of CVD admissions in the South West region of Cameroon.MethodsThis retrospective descriptive study included all adult patients admitted for CVD in the medical unit of the Buea Regional Hospital between Jan 2016 and December 2017.ResultsOut of the 3140 patients admitted, 499(15.9%) had CVD. There were 304(60.9%) females. The mean age was 58.7±16.2 years. There was no age difference between men and women (59.7 years vs 58.1years, p = 0.29). The most commonly affected age group was those aged 50–59 years (22%). Heart failure (38.5%), stroke (33.3%) and uncontrolled hypertension (22.4%) were the most prevalent CVDs. The length of hospital stay ranged from 1 to 37 days with a median length of hospital stay of 7 days. In-hospital case fatality was 78(15.8%). Mortality was higher in women compared to men (9% vs 7%, p = 0.43). The case fatality for stroke was higher compared to case fatality for heart failure (21.7% vs 16.7%, p = 0.23).ConclusionCVDs are a common cause of hospital admission in this semi-urban setting, dominated by heart failure. Women were disproportionately affected and it was associated with high mortality. Prevention, early detection and management of risk factors for cardiovascular disease are imperative given the growing burden of CVD in SSA to reduce CVD morbidity and mortality.

ObjectiveRheumatic heart disease (RHD) prevails as a major public health problem in sub-Saharan Africa. In Cameroon, reports on RHD have been so far limited to a few cities. We sought to describe the demographic, clinical and echocardiographic features of rheumatic heart disease in the Buea Regional Hospital, South West region of Cameroon. Echocardiography reports between June 2016 and June 2017 were reviewed. The diagnosis of RHD was based on the World Heart Federation Criteria for the diagnosis of RHD.ResultsA total of 669 echocardiograms were performed over the 1 year study period. Twenty-one (3.1%) had a definite echocardiographic diagnosis of RHD. There were 14 (66.7%) females. The age range was 13–94 years with a mean age of 47.8 ± 20.3 years. The most common indications for echocardiography were heart failure (47.6%), and dyspnea (42.9%). The mitral valve was the most commonly affected valve in 80.9% of cases. The most common valve lesion was isolated mitral stenosis (42.9%), followed by isolated mitral regurgitation (28.6%). There were no lesions on the tricuspid and pulmonic valves. Severe lesions were found in 80.9% of the patients. The complications were pulmonary hypertension (66.7%) and atrial fibrillation (9.5%).

BackgroundInfective endocarditis is a deadly disease if not promptly treated with antibiotics either in association with cardiac surgery or not. Cardiac complications are the most common complications seen in infective endocarditis. Heart failure remains the most common cause of mortality and the most common indication for cardiac surgery in patients with infective endocarditis which is increasingly available in resource limited settings.Case presentationWe report a case of native valve infective endocarditis of the aortic valve in a 27-year old female in a semi-urban setting in Cameroon complicated by severe aortic valve regurgitation and heart failure. She presented with a 2 month history of fever and a 2 weeks history of rapidly worsening shortness of breath. Emergency cardiac surgery was indicated which unfortunately could not be performed leading to the death of the patient.ConclusionsIn spite of improvement in availability of diagnostic and therapeutic modalities for cardiovascular emergencies, affordability is still a challenge. Universal health coverage is advocated else the ravages of premature mortality from cardiovascular diseases may continue to remain unchecked in Sub-Saharan Africa.
