“…The patients had an average disease duration of 8 ± 2.74 years, and more men than women were affected. A study of the development of heart failure among subjects with left bundle branch block showed that these subjects have a high prevalence of idiopathic dilated cardiomyopathy compared to other forms (39.1% vs. 4.8% p < 0.001), with a high frequency of hospitalization for heart failure (64.5% vs. 23.3%, p < 0.001), and that left ventricular ejection fraction was significantly lower in this group [ 12 ]. Myocardial infraction was studied in the Fes [ 13 ] and Rabat region [ 14 ], with results indicating a high percentage among men (aged 58 years and older), 51% in the Fes and 57.28% in the Rabat region, with smoking as the dominant risk factor.…”

OBJECTIVE: To provide a systematic review of studies on cardiovascular diseases (CVD) and their risk factors in the Moroccan population. METHODS: A systematic analysis was performed based on PRISMA guidelines by retrieving data bases (Medline, Embase, and other) using technical keywords in addition to manual research on official websites. Published studies in the English or French language, conducted in Morocco or concerning the Moroccan population within the last two decades, were identified. RESULTS: This is the first systematic review of CVD in Morocco. Data from 159 studies were retrieved and analyzed. Most studies were written in the English language (75.89%) and published between 2010 and 2019 (85.47%). The mortality rate caused by CVD in Morocco has reached 38%, with ischemic heart disease and stroke as the main events causing death (31.0% and 22.5% respectively). The risk factors present in the population studied were headed by tobacco smoking (45- 50%), followed by physical inactivity (21.1%), elevated rate of hypertension (25.3%), and depression (5.47%). Impacted by a high rate of illiteracy and poverty and an unprepared health care system in Morocco, these numbers are expected to increase over the next decade. CONCLUSIONS: Based on these alarming incidences, investment in scientific research and epidemiological studies should be increased to determine the needs of the local population. The available evidence shows that the risk of cardiovascular disease and the associated mortality is very high in Morocco and will rise in the next years prospectively, which calls for urgent multi-sectorial approaches and treatment strategies.

“…Further risk factors include hypertension, hyperlipidemia, smoking cigarettes, and male gender [ 1 , 4 ]. While diabetes mellitus (DM) is considered a protective factor or an independent factor in most reported cases, in Saudi Arabia, one study found that DM was associated with many CAE patients [ 4 , 8 ]. Other etiologies can contribute to the development of CAE such as vasculatides (Kawasaki disease, polyarteritis nodosa), connective tissue diseases (rheumatoid arthritis, systemic lupus erythematous, scleroderma), Marfan syndrome, and iatrogenic causes (stenting, angioplasty, coronary atherectomy) [ 4 - 7 ].…”

Coronary artery ectasia (CAE), also known as aneurysmal coronary artery disease, is defined as an abnormal diffuse (ectasia) or segmental (aneurysmal) dilatation of any branch of the coronary arteries. It is a well-recognized entity with 1.2-4.9% prevalence. Our case is a 46 year old male with no prior medical problem who presented to the ER with inferior ST elevation myocardial infarction (STEMI). The Coronary angiogram revealed multiple ectatic segments in the right coronary artery (RCA) with 100% stenosis in the middle segment. Upon wiring the RCA a big clot burden was noted on the ectatic segment. We planned to keep him on aggrastat infusion for 24 hours then re-cath him. The second cath showed complete resolution of the clot and the lesion was stented with drug eluting stent showing excellent final result. We found that our case is interesting and unique in exploring the association of CAE that presents with STEMI and how to treat it safely in the cath lab, knowing that CAE is an uncommon finding during coronary angiography. CAE is associated with many coronary artery disease (CAD) risk factors and etiologies as well as pathologic progression. Patients with CAE are usually asymptomatic but can still present with symptoms of coronary artery occlusion. There is still no standard treatment specific for CAE itself, but when presenting with occlusive symptoms, management is guided by the extent of occlusion similar to CAD.

“…The usual sequences of conduction changes dramatically in LBBB, which results in specific image on the ECG (1). The left bundle branch receives its primary blood supply from the LAD, particularly in the first segment while to the right bundle branch, the right and circumflex coronary arteries may supply some collateral flow (2). As for right bundle, conduction in the left bundle can be compromised by both structural and functional factors.…”

Introduction and Aim: Left bundle branch block (LBBB), is seen on the electrocardiograms, when the His-Purkinje system disrupts the normal sequence of activation is changed in the left bundle branch block, leading to specific appearance on the electrocardiograms. Left bundle branch blocks usually occur in patients associated with advanced heart conduction disorders. In this study we aimed to study the prevalence of significant CAD in patients with chest pain and left bundle branches block sent to invasive coronary angiography and study clinical and angiography with distribution of CAD risk factors in our study population. Methodology: This investigation is a single center retrospective cohort study that included 400 patients who underwent coronary angiography with left bundle branch block on their ECGs. The study was carried out in the Iraqi Center for Heart Disease between April 2017 and May 2022. Data regarding their age, gender, related risk factors, electrocardiography, echo and left ventricular function was noted. Data was subjected to statistical analysis using the Minitab program. Results: The prevalence of CAD was 41% among the 400 patients who had LBBB. Demographic data showed age, hypertension, and diabetes mellitus to be a risk factor associated with CAD. The related anatomy of the left bundle branch block in 98 patients showed single or multiple coronary artery disease and likely reduced ejection fraction (<50%). Conclusion: The prevalence of LBBB is more common in males than in females. The biggest risk factor for cardiovascular disease in those with LBBB and coronary artery disease is hypertension, which is followed by age and diabetes mellitus. Thus, coronary angiography should be used in cardiac tests to identify CAD in individuals with LBBB.
