Background: Hypertension is associated with considerable morbidity and mortality. Improvement of its management to reduce adverse cardiovascular outcomes will require an understanding of the patient characteristics and treatment factors associated with uncontrolled blood pressure. Factors that affect blood pressure control have not been sufficiently described in Cameroon. The main goal of our study was to determine the predictors of blood pressure control in patients with hypertension in an urban city in Cameroon.Methods: This was descriptive cross-sectional study from five outpatient hypertension consultation units in Hospitals in Yaoundé. Controlled hypertension was defined as blood pressure ≤140/90 mmHg. Logistic regression was used to determine factors associated with blood pressure control.Results: Among the 440 patients enrolled in the survey, 280 (63.6%) were females. The mean age was 61 (SD ±11) years. Mean systolic blood pressure (SBP) was 147 mmHg and mean diastolic blood pressure (DBP) was 88 mmHg. Only 36.8% of patients had their mean blood pressure controlled (BP ≤140/90 mmHg).Multivariable logistic regression analysis revealed good adherence to anti-hypertensive medications (OR= 3.99; 95% CI: 2.20-7.23; P<0.000) and dietary lifestyle changes (OR =1.5; 95% CI: 0.53-2.49; P=0.031) to be factors independently associated with controlled hypertension.Conclusions: Only one out of three patients has their blood pressure controlled. The results of our study suggest that good adherence to treatment are important factors for tight blood pressure control in primary care. Further identification of patients at risk of non-adherence to treatment and poor blood pressure control can lead to targeted interventions to reduce hypertension related morbidity and mortality in this setting.

BackgroundSub-Saharan Africa is undergoing epidemiological transition with an increase in the prevalence of cardiovascular diseases that will add to the already devastating burden of infectious diseases such as human immunodeficiency virus infection. Human immunodeficiency virus infection is increasingly being recognized as an important etiological factor for dilated cardiomyopathy with the potential complication of intraventricular thrombus. However, biventricular thrombi are extremely rare. We report on a rare finding of biventricular thrombi in dilated cardiomyopathy in a patient with human immunodeficiency virus infection in Cameroon.Case presentationA 52-year old Cameroonian male patient with human immunodeficiency virus infection since 4 years, longstanding heavy alcohol consumption and cigarette smoking presented with gradually worsening shortness of breath, fatigue, persistent dry cough and lower extremity swelling of about two weeks duration. Congestive heart failure was diagnosed. Echocardiography showed left ventricular chamber enlargement with severe left ventricular systolic dysfunction and biventricular thrombi. The thrombi were immobile and regular in configuration, suggesting they were old. He was treated with a conventional heart failure treatment including loop diuretics and angiotensin converting enzyme inhibitors and anticoagulants for the biventricular thrombi. Six months later, a control echocardiography showed a significant decrease in the size of the thrombi. There was no evidence of systemic or pulmonary embolization during follow up.ConclusionDilated cardiomyopathy may be seen in patients with human immunodeficiency virus infection, although other mechanisms needs to be assessed, but the occurrence of biventricular thrombi is rare.

Atrial fibrillation (AF) is a commonly encountered complication in intensive care. The causes of AF are widespread & thought to be an electrolyte disturbance or altered intravascular volume, but recent evidence suggesting that vasopressor dose & raised MAP also are indicated. There is little uniformity or guidance in the management of this arrhythmia. ObjectivesNew onset atrial fibrillation occurs in about 10% of patients admitted to intensive care and has an adverse effect on several outcome measures. The objective of this audit was to assess the incidence of new onset AF in critical illness, its causes, treatments & to evaluate a proposed target as laid by the Royal College of Anaesthetists (RCOA).
