Background: Whereas the increasing burden of acute myocardial infarction (MI) has been reported in sub-Saharan Africa, little is known about short- and long-term prognosis following acute MI.

Objectives: The purpose of this study was to assess in-hospital, 30-day, and 1-year all-cause mortality and adverse outcomes in patients with MI hospitalized at a cardiac center in Côte d'Ivoire.

Methods: This prospective cohort study used data from the REgistre des syndromes coronariens Aigus de CôTe d'IVoire (REACTIV).

Background: From a large observational acute coronary syndrome registry in Côte d'Ivoire, we aimed to assess incidence, clinical presentation, management, and in-hospital outcomes for type 2 myocardial infarction (T2MI) compared with type 1 MI.

Methods And Results: We conducted a cross-sectional monocentric study using data from REACTIV (Registre des Infarctus de Côte d'Ivoire) at the Abidjan Heart Institute. All patients hospitalized with MI between 2018 and 2022 who underwent coronary angiography were included.

Spontaneous coronary artery dissection is a rare but potentially life-threatening condition that predominantly affects women, particularly during pregnancy or postpartum period. We present a case of peripartum spontaneous coronary artery dissection in a 41-year-old African woman, highlighting the clinical presentation, diagnostic challenges, and management strategies.

Underlying coronary artery disease (CAD) is increasingly considered to be a key issue in the pathophysiology of type 2 myocardial infarction (T2MI). In T2MI, which is attributable to a mismatch between oxygen supply/demand, CAD is common and appears to be more severe than in type 1 myocardial infarction (T1MI). Little is known about the heterogeneous mechanisms that cause supply/demand imbalance and non-coronary triggers leading to myocardial ischemia or about how they are potentially modulated by the presence and severity of CAD.

Background: A new classification of type 1 and 2 myocardial infarction (MI) derived from the fourth universal definition of MI (UDMI) has been recently proposed, based on pathophysiology of coronary artery disease (CAD). We assessed the impact of this new MI categorization on epidemiology and outcomes, considering type 1 MI (T1MI) and type 2 MI (T2MI), with and without CAD.

Methods: Retrospective study including all consecutive patients hospitalized for an acute MI in a multicenter database (RICO).

Introduction: Heart rate recovery (HRR) measured during stress tests, assesses the vago-sympathetic balance. It is a known prognostic and predictive parameter of cardiovascular mortality that is believed to be correlated with the presence and severity of coronary artery disease. The aim of this work was to assess the predictive value of heart rate recovery in the diagnostic and severity of coronary lesions in a major metropolis of sub-Saharan Africa where access to specialist care is unevenly distributed.

Introduction-objective: Acute coronary syndromes (ACS) are the leading cause of death among the elderly in sub-Saharan Africa. The aim of this study was to analyze the characteristics of ACS among the elderly at the Abidjan Heart Institute.

Materials And Methods: Cross-sectional study from January 1, 2015, to December 31, 2019.

Aim: To determine the prevalence and determinants of different types of echocardiographic left ventricular remodeling in African black hypertensive patients.

Patients And Methods: A transversal descriptive study was conducted from January 1, 2015, to March 31, 2016, in the external explorations department of the Abidjan Heart Institute-Côte d'Ivoire. Transthoracic cardiac echo-graphs were performed in 524 (251 women) hypertensive subjects according to the American Society of Echocardiography convention.

Background Data in the literature on acute coronary syndrome in sub-Saharan Africa are scarce. Methods and Results We conducted a systematic review of the MEDLINE (PubMed) database of observational studies of acute coronary syndrome in sub-Saharan Africa from January 1, 2010 to June 30, 2020. Acute coronary syndrome was defined according to current definitions.

Background: Although patients with familial heterozygous hypercholesterolemia (FH) have a high risk of early myocardial infarction (MI), the coronary artery disease (CAD) burden in FH patients with acute MI remains to be investigated.

Methods: The data for all consecutive patients hospitalized in 2012-2019 for an acute MI and who underwent coronary angiography were collected from a multicenter database (RICO database). FH (n = 120) was diagnosed using Dutch Lipid Clinic Network criteria (score ≥ 6).

Optimal antithrombotic therapy after percutaneous coronary intervention (PCI) in patients on oral anticoagulants (OAC) remains a clinical conundrum. In fact, combining an OAC with dual antiplatelet therapy (triple antithrombotic therapy, TAT) increases the risk of bleeding. Clopidogrel is the only thienopyridine recommended in TAT patients.

This review was conducted to emphasize the complex interplay between atrial fibrillation (AF) and myocardial infraction (MI). In type 1 (T1) MI, AF is frequent and associated with excess mortality. Moreover, AF after hospital discharge for T1MI is not rare, suggesting the need to improve AF screening and to develop therapeutic strategies for AF recurrence.

Introduction: Renal transplant recipients have a high peri-operative risk for cardiovascular events. The post-transplantation period also carries a risk of myocardial infarction (MI). Coronary artery disease (CAD) is a leading cause of death in these patients.

Aim: The aim of the study was to determine the relationship between acute hyperglycaemia and in-hospital mortality in black Africans with acute coronary syndromes (ACS).

Methods: From January 2002 to December 2017, 1 168 patients aged ≥ 18 years old, including 332 patients with diabetes (28.4%), consecutively presented to the intensive care unit of the Abidjan Heart Institute for ACS.

Background: Implementation of primary percutaneous coronary intervention (PCI) in sub-Saharan Africa remains a challenging issue. The aim of this study was to report the results of primary PCI and outcomes in the catheterisation laboratory of the Abidjan Heart Institute.

Methods: Between April 2010 and March 2019, all patients aged 18 years presenting to the Abidjan Heart Institute for ST-segment elevation myocardial infarction (STEMI) over the study period and who underwent primary PCI were included.

Article Synopsis
  • This study investigates the prevalence and severity of familial hypercholesterolemia (FH) among French patients hospitalized for acute myocardial infarction (MI) over a 16-year period.
  • Among 11,624 patients, 2.1% were diagnosed with "probable/definite" FH, who were notably younger and had different health profiles compared to those with "unlikely" FH.
  • Findings revealed that patients with FH experienced more extensive and severe coronary artery disease, in addition to highlighting the low usage rates of preventive lipid-lowering treatments like statins and ezetimibe.

Background: Major in-hospital mortality rate in patients with ST-segment Elevation Myocardial Infarction (STEMI) in Sub-Saharan Africa has been reported. Data on follow-up in these patients with STEMI are scarce. We aimed to assess medium and long-term prognosis in patients with STEMI admitted to Abidjan Heart Institute.
