This pilot study describes the overall design and results of the Program for the Evaluation and Management of the Cardiac Events registry for the Middle East and North Africa (MENA) Region. This prospective, multi-center, multi-country study included patients hospitalized with acute myocardial infarction (AMI) and/or acute heart failure (AHF). We evaluated the clinical characteristics, socioeconomic and educational levels, management, in-hospital outcomes, and 30-day mortality rate of patients that were admitted to one tertiary-care center in each of 14 Arab countries in the MENA region. Between 22 April and 28 August 2018, 543 AMI and 381AHF patients were enrolled from 14 Arab countries (mean age, 57±12 years, 82.5% men). Over half of the patients in both study groups had low incomes with limited health care coverage, and limited education. Nearly half of the cohort had a history of diabetes mellitus, hypertension, or hypercholesterolemia. Among patients with ST-elevation myocardial infarctions, 56.4% received primary percutaneous interventions, 24% received thrombolysis, and 19.5% received no acute reperfusion therapy. The main causes of AHF were ischemic heart diseases (55%) and primary valvular heart diseases (15%). The in-hospital and 30-day mortality rates were 2.0% and 3.5%, respectively, for AMI, and 5.4% and 7.0%, respectively, for AHF. This pilot study revealed a high prevalence of cardiovascular risk factors in patients with AMI and AHF in Arab countries, and low levels of socioeconomic and educational status. Future phases of the study will improve our understanding of the impact that these factors have on the management and outcomes of cardiac events in these patient populations.

The Program for the Evaluation and Management of Cardiac Events in the Middle East and North Africa (PEACE MENA) is a prospective registry program in Arabian countries that involves in patients with acute myocardial infarction (AMI) or acute heart failure (AHF). This prospective, multi-center, multi-country study is the first report of the baseline characteristics and outcomes of inpatients with AMI who were enrolled during the first 14-month recruitment phase. We report the clinical characteristics, socioeconomic, educational levels, and management, in-hospital, one month and one-year outcomes. Between April 2019 and June 2020, 1377 patients with AMI were enrolled (79.1% males) from 16 Arabian countries. The mean age (± SD) was 58 ± 12 years. Almost half of the population had a net income < $500/month, and 40% had limited education. Nearly half of the cohort had a history of diabetes mellitus, hypertension, or hypercholesterolemia; 53% had STEMI, and almost half (49.7%) underwent a primary percutaneous intervention (PCI) (lowest 4.5% and highest 100%). Thrombolytics were used by 36.2%. (Lowest 6.45% and highest (90.9%). No reperfusion occurred in 13.8% of patients (lowest was 0% and highest 72.7%).Primary PCI was performed less frequently in the lower income group vs. high income group (26.3% vs. 54.7%; P<0.001). Recurrent ischemia occurred more frequently in the low-income group (10.9% vs. 7%; P = 0.018). Re-admission occurred in 9% at 1 month and 30% at 1 year, whereas 1-month mortality was 0.7% and 1-year mortality 4.7%. In the MENA region, patients with AMI present at a young age and have a high burden of cardiac risk factors. Most of the patients in the registry have a low income and low educational status. There is heterogeneity among key performance indicators of AMI management among various Arabian countries.

Prior acute coronary syndrome (ACS) registries in Saudi Arabia might not have accurately described the true demographics and cardiac care of patients with ACS. We aimed to evaluate the clinical characteristics, management, and outcomes of a representative sample of patients with acute myocardial infarction (AMI) in Saudi Arabia. We conducted a 1-month snap-shot, prospective, multi-center registry study in 50 hospitals from various health care sectors in Saudi Arabia. We followed patients for 1 month and 1 year after hospital discharge. Patients with AMI included those with or without ST-segment elevation (STEMI or NSTEMI, respectively). This program survey will be repeated every 5 years. Between May 2015 and January 2017, we enrolled 2233 patients with ACS (mean age was 56 [standard deviation = 13] years; 55.6% were Saudi citizens, 85.7% were men, and 65.9% had STEMI). Coronary artery disease risk factors were high; 52.7% had diabetes mellitus and 51.2% had hypertension. Emergency Medical Services (EMS) was utilized in only 5.2% of cases. Revascularization for patients with STEMI included thrombolytic therapy (29%), primary percutaneous coronary intervention (PCI); (42.5%), neither (29%), or a pharmaco-invasive approach (3%). Non-Saudis with STEMI were less likely to undergo primary PCI compared to Saudis (35.8% vs. 48.7%; respectively, p <0.001), and women were less likely than men to achieve a door-to-balloon time of <90 min (42% vs. 65%; respectively, p = 0.003). Around half of the patients with NSTEMI did not undergo a coronary angiogram. All-cause mortality rates were 4%, 5.8%, and 8.1%, in-hospital, at 1 month, and at 1 year, respectively. These rates were significantly higher in women than in men. There is an urgent need for primary prevention programs, improving the EMS infrastructure and utilization, and establishing organized ACS network programs. AMI care needs further improvement, particularly for women and non-Saudis.

Background Single centre studies support No Touch (NT) saphenous vein graft (SVG) harvesting technique. The primary objective of the SUPERIOR SVG study was to determine whether NT versus conventional (CON) SVG harvesting was associated with improved SVG patency 1 year after coronary artery bypass grafting surgery (CABG). Methods Adults undergoing isolated CABG with at least 1 SVG were eligible. CT angiography was performed 1-year post CABG. Leg adverse events were assessed with a questionnaire. A systematic review was performed for published NT graft patency studies and results aggregated including the SUPERIOR study results. Results Two hundred and-fifty patients were randomized across 12-centres (NT 127 versus CON 123 patients). The primary outcome (study SVG occlusion or cardiovascular (CV) death) was not significantly different in NT versus CON (NT: 7/127 (5.5%), CON 13/123 (10.6%), p  = 0.15). Similarly, the proportion of study SVGs with significant stenosis or total occlusion was not significantly different between groups (NT: 8/102 (7.8%), CON: 16/107 (15.0%), p  = 0.11). Vein harvest site infection was more common in the NT patients 1 month postoperatively (23.3% vs 9.5%, p  < 0.01). Including this study’s results, in a meta-analysis, NT was associated with a significant reduction in SVG occlusion, Odds Ratio 0.49, 95% Confidence Interval 0.29–0.82, p  = 0.007 in 3 randomized and 1 observational study at 1 year postoperatively. Conclusions The NT technique was not associated with improved patency of SVGs at 1-year following CABG while early vein harvest infection was increased. The aggregated data is supportive of an important reduction of SVG occlusion at 1 year with NT harvesting. Trial registration NCT01047449 .

Objective: This paper examines the nature of military and non-military challenges that had consequences for Gulf security via systematic analysis that combines theory and practice to outline a formula for understanding the factors that influence gulf security. The paper tackles multifaceted threats including: Iran's constant hegemony aspirations, uncertainty in Iraq, the war in Yemen, extremism and counterterrorism, and the influential effects of the Arab uprisings. The study looks also at the interaction between internal and external events and how it shapes the security posture. Methods: The realpolitik framework will be used along with descriptive analytical method to illustrate the evolving events and its effects on the gulf regional stability. Results: The gulf security was and remain to this day depends on the US role. Conclusion: The events of the Arab uprisings unveiled that the domestic challenges could play greater role in gulf stability than external challenges and the regional developments will impact gulf security.

Background: Peripheral Arterial Disease (PAD) is a marker of systemic atherosclerosis with an elevated risk of cardiovascular mortality and morbidity. This study was undertaken to identify the prevalence of PAD in patients presenting with acute coronary syndrome and do not have previous history of coronary artery disease in order to identify the missed opportunity in treating these patients and potentially avoiding such cardiovascular events. Methods: We prospectively collected data from consecutive patients who presented with acute coronary events over 4 months. PAD was diagnosed if the Ankle-Brachial index was less than 0.90 and/or if the patient had signs or symptoms suggestive for PAD. Risk factors and risk reduction therapy were compared between patients with and without PAD. Results: A total of 51 patients were recruited. The mean age for these patients was 62 years and 27% were women. Prevalence of PAD was 45%, of these, 61% were asymptomatic. Prevalence of PAD in patients with no previous history of CAD was 48%, of these, 64% were asymptomatic. There was no difference in atherosclerotic risk factors between patients with PAD compared to patients without PAD. Utilization of risk reduction was suboptimal in patients with PAD; only 61% were on aspirin, 48% were on statin therapy, 43% were on beta-blockers and 30% were on angiotensin converting enzymes inhibitors. Conclusion: There is a great opportunity in preventing acute coronary events that we are missing. This is can be achieved by recognizing patients with PAD (symptomatic or asymptomatic) and aggressively control their risk factors.

This study analyzes US foreign policy towards the GCC states during the two terms of the G. W. Bush administration in the period 2001-2008. It concentrates on describing and analyzing US interactions with Arabia; a region of central geo-political importance as it possesses bountiful proven oil reserves, upon which American and western prosperity depends. Furthermore, it provides a detailed account of US interests and strategic objectives in the Gulf region. Of particular interest to this study is exploring what associations can be made between the US's strategic relations with its GCC allies and the objectives of US grand strategy. This synthesis of analysis is appropriate to demarcate a proper framework that will enhance understanding of US-Gulf policy. US relations with the six GCC member states (Saudi Arabia, United Arab Emirates, Qatar, Kuwait, Oman and Bahrain) have been entrenched over a course of more than six decades and have evolved on solid foundations based on oil and security. Simultaneously, the US's relations with its Arab Gulf partners have experienced turning points and tumultuous periods in the aftermath of the trauma of September 11, due to which US relations with Saudi Arabia, in particular, were put under a tremendous strain. As a result, many scholars saw a remarkable change in US-Gulf policy. Conversely, this study argues that the Bush administration policy towards America's longtime allies in the Gulf region has been one of continuity as opposed to change and has not departed dramatically from the conventional policy. Interestingly, US economic and geo-political interests in the Gulf region have created a deep relationship between the US and its Gulf ‘friends’. Therefore, Gulf security has preoccupied American strategic thinking and preserving Arabia remains the core objective of US security engagement with the region. This security relationship is at the core of long term US-GCC relations and was never going to be affected by post-9/11 neoconservative ideologies.
