Objectives: The objectives of this study were to evaluate the prevalence of the right ventricular infarction and its diagnostic, therapeutic and prognostic characteristics. Patients and methods:A single center retrospective study was carried out between January 2011 and December 2014. Patients who were diagnosed with right ventricular infarction at electrocardiogram and echocardiography were recruited.Outcomes: Among the 159 patients hospitalized for myocardial infarction, 10 had myocardial infarction extended to the right ventricle (6.3%). It occurred on an inferior infarction in 7 cases out of 35 and anterior infarction in 3 cases out of 124. The mean age was 53 years and sex ratio M/F of 2.33. All patients had at least 3 cardiovascular risk factors. Right-sided heart failure was found in 4 patients. Right ventricular infaction was associated with inferior STEMI in 7 patients, and anterior STEMI in 3 patients. Echocardiography showed right ventricular dilatation and impaired right ventricular systolic function in respectively 6 cases. Thrombolysis was performed in 7 patients and rescue angioplasty in 1 case. A regressive cardiogenic collapse was noted in 6 cases and one death in 1 case. Conclusion:Right ventricular infarction is relatively rare and usually related to an extension of an inferior myocardial infarction. Hemodynamic instability is of worse prognosis.
Introduction: Peripheral arterial disease of the lower limbs (PAD) is a partial or total obliteration of one or more arteries intended for the lower limbs by atheroma. Its prevalence increases with age, but also with other major cardiovascular risk factors such as diabetes, smoking, high blood pressure and dyslipidemia. Its diagnosis is essentially based on arterial Doppler ultrasound, which studies the topography and extension of the lesions, thus constituting the essential tool for therapeutic decision-making. The objective was to describe the epidemiological and ultrasound profile of patients with atheromatous arterial stenosis of the lower limbs. Methodology: This was a cross-sectional descriptive study running from 1 January 2019 to 31 March 2020, we took a duration of 15 months. This study was carried out at the Conakry University Hospital (Donka and Ignace Deen Hospitals). Results: In our series, the average age was 64.7 ± 13 years, with a sex ratio of 1.04. The average age was 64.7 ± 13 years, with a sex ratio of 1.04. The average age of the women in our series was 64.7 ± 13 years. Risk factors were dominated by advanced age (78.67%), diabetes (58%), hypertension (57%) and physical inactivity (47.66%). Among the 300 patients, 145 were carriers of atheromatous arterial stenosis, or a frequency of 48.33%. The leg arteries were the most affected, followed by the common femoral arteries. Concerning the degree of stenosis, patients with stenosis greater than 70% were the most represented. Conclusion: Peripheral arterial disease of the lower limbs (AOMI) is a pathology not to be neglected in Guinea. Patients have several risk factors : stenosis is an important part of the ultrasound lesions of this disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
