The aim of this study was to estimate the prevalence of good anticoagulation in patients treated with VKA in Lomé and describe associated factors. Methods: This was a cross-sectional study conducted from November 2019 to October 2020 in the cardiology departments of two University teaching hospitals in Lomé (CHU Sylvanus Olympio and CHU Campus), involving patients on VKA for ≥3 months, with a target international normalized ratio (INR) of 2.5 and a therapeutic margin between 2 and 3. The quality of anticoagulation was assessed by the time in therapeutic range (TTR) which was assessed by the Rosendaal method. Good anticoagulation was defined by a TTR > 70%. Results: A total of 344 patients were included (mean age = 58 ± 13.8 years, women = 56.1%). Indications for VKA treatment were represented by venous thromboembolic disease (43.3%), supraventricular arrhythmia (28.2%), severe left ventricular systolic dysfunction (19.8%) and pulmonary hypertension (8.7%). The average TTR was 47.6 ± 20.8%. The rate of good anticoagulation was 17.7%. Factors associated with good anticoagulation were the use of fluindione vs acenocoumarol (OR = 11.17;95% CI: 3.2 - 39.6;p = 0.0002), concomitant low-dose aspirin (OR 4.44;95% CI: 1.4 - 13.9;p = 0.01) and INR monitoring exclusively by the patient himself (OR = 4.92;95% CI: 1.5 - 16.3;p = 0.008). The rate of thromboembolic and hemorrhagic complications was each 2.6% and was not correlated with the quality of anticoagulation. Quality of anticoagulation by VKAs was poor in our practice. Factors associated with good anticoagulation were the use of fluindione vs acenocoumarol, concomitant low-dose aspirin and monitoring of INR exclusively by the patient himself. Conclusion: The quality of oral anticoagulation by VKAs could be improved in our practice by the creation of anticoagulation clinics for better therapeutic education of patients and efficient management of VKA dose, and the use of prescription assistance software.展开更多

We aim to determine the frequency of uncontrolled hypertension in hypertensive patients followed up as an outpatient at the campus university hospital of Lome (Togo) and to search for the associated factors. Methodology: The study was cross-sectional, descriptive and analytical, carried out from February (2022) to August 2022 in 260 hypertensive patients aged 22 years old, followed up (on an) as an outpatient for at least 3 months at the Lome University Hospital campus. A univariate then multivariate analysis were conducted in order to highlight the most common factors significantly linked to uncontrolled. Results: The mean age of hypertensives was 56.4 ± 12.7 years, the sex ratio (M/F) was 0.59. Prevalence of uncontrolled blood pressure was 42%. Associated Factors to poor blood pressure control in our study were age > 60 years (OR = 1.6 CI [1.17 - 2.50]), low socio-economic level (OR = 2.2 CI [1.96 - 4.33]), high cardiovascular risk level (OR = 3.1 CI [2.18 - 4.52]), non-adherence to regular blood pressure monitoring (OR = 3.3 CI [2.21 - 5.55]), low compliance to treatment (OR = 4.1 CI [2.33 - 6.76]) and a chronic renal failure (OR = 2.1 CI [1.21 - 3.10]). Conclusion: Nearly half of the hypertensives in our study had poorly controlled blood pressure by antihypertensive treatment medication. The factors of this poor control were age > 60 years, low socio-economic level, high or very high level of cardiovascular risk, low compliance to treatment, and renal failure.展开更多

There was a male predominance with a sex ratio of 2.63. The main countries of evacuation were France (50%), Tunisia (25%) and Ivory Coast (20%). The main indications of coronary angiography were myocardial infarction in 47.5%, NSTEMI (22.5%) and ischemic heart disease (15%). Fifty-five percent of the patients had monotroncular involvement. Angioplasty was performed in 16 patients, 3 patients had bypass surgery and only one patient had medical treatment. Sixty percent of patients received an active stent and 20% a bare stent. The total cost of the 40 evacuations was four hundred and fifty one thousand four hundred and nineteen US dollars (US$451,419). The average cost per evacuation was eleven thousand two hundred and eighty-six US dollars (US$11,286), or 182 times the Togolese minimum wage. At the announcement of the disease and evacuation, 40% had been afraid and 35% had accepted their illness. Fifty-five percent perceived evacuation as a healthy outcome. In 25% of cases the coronary angiography was simple and 20% found it painful. After the coronary angiography 40% had regained hope of recovery, 37.5% had accepted their result and 37.5% were happy with the outcome. <b>Conclusion: </b>Coronary artery disease is a serious pathology in terms of cardiovascular morbidity and mortality, especially its severe form, which is myocardial infarction, the treatment of which requires angioplasty.

It is a major cause of sudden death in young people with no obvious heart structural abnormality. The electrocardiogram can be dynamic over time with sometimes normalization. Several pathophysiological conditions are known to induce the electrocardiographic expression of the syndrome. We report here the case of a 65-year-old hypertensive man, without syncope or family sudden death history who was hospitalized for shigella gastroenteritis. Electrocardiogram during fever showed an incomplete block and ST segment elevation with negative T waves in V1 and V2 suggested type 1 Brugada syndrome. Troponin was negative. Electrocardiogram after fever recovered an incomplete right block and normalization of the ST segment. Electrocardiogram should be performed in patients admitted to the emergency unit for infectious syndrome in our countries. This may reveal a number of patients with Brugada syndrome abnormalities.展开更多
