The impact of left ventricular dysfunction on clinical outcomes following revascularization is not well established in patients with unprotected left main coronary artery disease (ULMCA). In this study, we evaluated the impact of left ventricular ejection fraction (LVEF) on clinical outcomes of patients with ULMCA requiring revascularization with percutaneous coronary intervention (PCI) compared with coronary artery bypass graft (CABG).The details of the design, methods, end points, and relevant definitions are outlined in the Gulf Left Main Registry: a retrospective, observational study conducted between January 2015 and December 2019 across 14 centres in 3 Gulf countries. In this study, the data on patients with ULMCA who underwent revascularization through PCI or CABG were stratified by LVEF into three main subgroups; low (l-LVEF40%), mid-range (m-LVEF 40-49%), and preserved (p-LVEF ≥50%). Primary outcomes were hospital major adverse cardiovascular and cerebrovascular events (MACCE) and mortality and follow-up MACCE and mortality.A total of 2137 patients were included; 1221 underwent PCI and 916 had CABG. During hospitalization, MACCE was significantly higher in patients with l-LVEF [(10.10%), P = 0.005] and m-LVEF [(10.80%), P = 0.009], whereas total mortality was higher in patients with m-LVEF [(7.40%), P = 0.009] and p-LVEF [(7.10%), P = 0.045] who underwent CABG. There was no mortality difference between groups in patients with l-LVEF. At a median follow-up of 15 months, there was no difference in MACCE and total mortality between patients who underwent CABG or PCI with p-LVEF and m-LVEF.CABG was associated with higher in-hospital events. Hospital mortality in patients with l-LVEF was comparable between CABG and PCI. At 15 months' follow-up, PCI could have an advantage in decreasing MACCE in patients with l-LVEF.

Real-world data for managing patients with diabetes and left main coronary artery (LMCA) disease are scarce. We compared percutaneous coronary intervention (PCI) outcomes versus coronary artery bypass grafting (CABG) in diabetes and LMCA disease patients.We retrospectively studied patients with LMCA presented to 14 centers from 2015 to 2019. The study included 2138 patients with unprotected LMCA disease; 1468 (68.7 %) had diabetes. Patients were grouped into; diabetes with PCI (n = 804) or CABG (n = 664) and non-diabetes with PCI (n = 418) or CABG (n = 252).In diabetes, cardiac (34 (5.1 %) vs. 22 (2.7 %); P = 0.016), non-cardiac (13 (2 %) vs. 6 (0.7 %); P = 0.027) and total hospital mortality (47 (7.1 %) vs. 28 (3.5 %); P = 0.0019), myocardial infarction (45 (6.8 %) vs. 11 (1.4 %); P = 0.001), cerebrovascular events (25 (3.8 %) vs. 12 (1.5 %); P = 0.005) and minor bleeding (65 (9.8 %) vs. 50 (6.2 %); P = 0.006) were significantly higher in CABG patients compared to PCI; respectively. The median follow-up time was 20 (10-37) months. In diabetes, total mortality was higher in CABG (P = 0.001) while congestive heart failure was higher in PCI (P = 0.001). There were no differences in major adverse cerebrovascular events and target lesion revascularization between PCI and CABG. Predictors of mortality in diabetes were high anatomical SYNTAX, peripheral arterial disease, chronic kidney disease, and cardiogenic shock.In this multicenter retrospective study, we found no significant difference in clinical outcomes during the short-term follow-up between PCI with second-generation DES and CABG except for lower total mortality and a higher rate of congestive heart failure in PCI group of patients. Randomized trials to characterize patients who could benefit from each treatment option are needed.

Introduction Our research sought to assess the psychological and social wellbeing of paramedics in Riyadh City in Saudi Arabia during the COVID 19 pandemic. It also aimed to assess the therapeutic assistance provided to pre-hospital care givers during the pandemic. Methods In this quantitative cross-sectional analysis an assessment of 106 paramedics was undertaken from data obtained from 28 September to 10 November 2020. The authenticity and durability of Pilot and the Cronbach have been added. Results Of the 106 paramedics surveyed, 60 (56.6%) were 30–39 years of age; 101 were male (95.3%). The mean average psychological wellbeing of the paramedics was 6.41 with the standard deviation of 2.42. Family and friends’ average social support score was 9.2 in norm 2.6 deviation. Conclusion Our study showed that during the COVID-19 pandemic paramedics suffered from social and psychological depression. Paramedics must be protected from the socioeconomic and psychological difficulties they face every day in order to combat the COVID-19 pandemic.

Data on spontaneous coronary artery dissection (SCAD) is based on European and North American registries. We assessed the prevalence, epidemiology, and outcomes of patients presenting with SCAD in Arab Gulf countries. Patients (n = 83) were diagnosed with SCAD based on angiographic and intravascular imaging whenever available. Thirty centers in 4 Arab Gulf countries (Kingdom of Saudi Arabia, United Arab Emirates, Kuwait, and Bahrain) were involved from January 2011 to December 2017. In-hospital (myocardial infarction [MI], percutaneous coronary intervention, ventricular tachycardia/fibrillation, cardiogenic shock, death, implantable cardioverter-defibrillator placement, dissection extension) and follow-up (MI, de novo SCAD, death, spontaneous superior mesenteric artery dissection) cardiac events were recorded. Median age was 44 (37-55) years, 42 (51%) were females and 28.5% were pregnancy-associated (21.4% were multiparous). Of the patients, 47% presented with non-ST-elevation acute coronary syndrome, 49% with acute ST-elevation myocardial infarction, 12% had left main involvement, 43% left anterior descending, 21.7% right coronary, 9.6% left circumflex, and 9.6% multivessel; 52% of the SCAD were type 1, 42% type 2, 3.6% type 3, and 2.4% multitype; 40% managed medically, 53% underwent percutaneous coronary intervention, 7% underwent coronary artery bypass grafting. Females were more likely than males to experience overall (in-hospital and follow-up) adverse cardiovascular events ( P = .029).

Currently, gender is not considered in the choice of the revascularization strategy for patients with unprotected left main coronary artery (ULMCA) disease. This study analyzed the effect of gender on the outcomes of percutaneous coronary intervention (PCI) vs coronary artery bypass grafting (CABG) in patients with ULMCA disease. Females who had PCI (n = 328) were compared with females who had CABG (n = 132) and PCI in males (n = 894) was compared with CABG (n = 784). Females with CABG had higher overall hospital mortality and major adverse cardiovascular events (MACE) than females with PCI. Male patients with CABG had higher MACE; however, mortality did not differ between males with CABG vs PCI. In female patients, follow-up mortality was significantly higher in CABG patients, and target lesion revascularization was higher in patients with PCI. Male patients had no difference in mortality and MACE between groups; however, MI was higher with CABG, and congestive heart failure was higher with PCI. In conclusion, women with ULMCA disease treated with PCI could have better survival with lower MACE compared with CABG. These differences were not evident in males treated with either CABG or PCI. PCI could be the preferred revascularization strategy in women with ULMCA disease.

Coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in revascularization of left main coronary artery (LMCA) disease has been evaluated in previous studies. However, there has been minimal study of the relationship between co-existing non-coronary atherosclerosis (NCA) and LMCA disease revascularization. We aim to examine this relationship. The Gulf-LM study is a retrospective analysis of unprotected LMCA revascularization cases undergoing PCI with second generation drug-eluting stent vs CABG across 14 centers within 3 Gulf countries between January 2015 and December 2019. A total of 2138 patients were included, 381 with coexisting NCA and 1757 without. Outcomes examined included major adverse cardiovascular and cerebrovascular events (MACCE), cardiac and non-cardiac death, and all bleeding. In patients with NCA, preexisting myocardial infarction and congestive heart failure were more common, with PCI being the most common revascularization strategy. A statistically significant reduction in in-hospital MACCE and all bleeding was noted in patients with NCA undergoing PCI as compared to CABG. At a median follow-up of 15 months, MACCE and major bleeding outcomes continued to favor the PCI group, though no such difference was identified between revascularization strategies in patients without NCA.In this multicenter retrospective study of patients with and without NCA who require revascularization (PCI and CABG) for unprotected LMCA disease, PCI demonstrated a better clinical outcome in MACCE both in-hospital and during the short-term follow-up in patients with NCA. However, no such difference was observed in patients without NCA.

Coronary artery bypass surgery (CABG) has been the standard of care for revascularization for patients with obstructive unprotected left main coronary disease (ULMCA). There have been multiple randomized and registry data demonstrating the technical and clinical efficacy of PCI in certain patients with ULMCA. The purpose of this study is to evaluate clinical outcomes of ULMCA PCI as compared to CABG in patients requiring revascularization in three Gulf countries. All ULMCA cases treated by PCI with DES versus CABG were retrospectively identified from 14 centers in 3 Arab Gulf countries (KSA, UAE, and Bahrain) from January 2015 to December 2019. In total, 2138 patients were included: 1222 were treated with PCI versus 916 with CABG. Patients undergoing PCI were older, and had higher comorbidities and mean European System for Cardiac Operative Risk Evaluation (EuroSCORE). Aborted cardiac arrest and cardiogenic shock were reported more in the PCI group at hospital presentation. In addition, lower ejection fractions were reported in the PCI group. In hospital mortality and major adverse cardiovascular and cerebrovascular events (MACCE) occurred more in patients undergoing CABG than PCI. At median follow-up of 15 months (interquartile range, 30), no difference was observed in freedom from revascularization, MACCE, or total mortality between those treated with PCI and CABG. While findings are similar to Western data registries, continued follow-up will be needed to ascertain whether this pattern continues into latter years.

Background: The Coronavirus Disease 2019 (COVID-19) outbreak has affected all regions and countries with varying impacts based on infection rates and the associated fatalities. This study aimed to assess knowledge, attitude, and practices (KAP) toward the COVID-19 pandemic among Saudi Arabians. Methods: The study utilized a cross-sectional research design. Web-based questionnaires’ link was sent via emails and social media and sample was 5483 respondents. Purposive sampling ensured only those participants that met the inclusion criteria. Validity and reliability were checked. Results: Most respondents, 67.9%, were aged between 18 and 35 years and highest level of education university. The findings based on the study objectives indicated a high level of knowledge about COVID-19, which indicated early detection can improve treatment by 4701 (85.7%), the disease can be treated at home 84.6%, the disease can be prevented and avoided when precautions are taken 96.8%. Moreover, 37.2% of the respondents still used herbal products to prevent and treat the disease, and 72.1% indicating immediate visit the physician when there are symptoms. Conclusion: Promoting public knowledge about COVID-19 by the Ministry of Health is paramount in defeating this disease. Providing more education and awareness for public to comply with WHO’s recommendation is recommended.
