ABSTRACT

Background: Previous registries have shown a younger average age at presentation with cardiovascular diseases in the Middle East (ME), but no study has examined atrioventricular block (AVB). Moreover, these comparisons are confounded by younger populations in the ME. We sought to describe the average age at presentation with AVB in ME and quantify the effect of being from ME, adjusted for the overall younger population. Methodology: This was a retrospective analysis of PANORAMA registries, which collected data on patients who underwent cardiac rhythm device placement worldwide. Countries with a median population age of ≤30 were considered 'young countries'. Multivariate linear regression was performed to assess the effect of being from ME, adjusted for being from a 'young country', on age at presentation with AVB. Results: The study included 5,259 AVB patients, with 640 (8.2%) from the ME. Mean age at presentation was seven years younger in ME than in other regions (62.9 ± 17.8 vs. 70 ± 14.1, P < 0.001). Being from a 'young country' was associated with 5.6 years younger age at presentation (95%CI -6.5--4.6), whereas being from ME was associated with 3.1 years younger age at presentation (95%CI -4.5--1.8), (P < 0.001 for both). Conclusion: The average age at presentation with AVB in the ME is seven years younger than in other regions. While this is mostly driven by the overall younger population, being from the ME appears to be independently associated with younger age. Determinants of the earlier presentation in ME need to be assessed, and care should be taken when applying international recommendations.

ABSTRACT

Objectives: This study aimed to determine the characteristics of antibiotic prophylaxis (AP) utilization and the level of adherence of King Saud University Medical City (KSUMC) staff to the latest American Heart Association (AHA) guidelines for AP for infective endocarditis (IE) in cardiac patients undergoing dental procedures. Methods: The study was conducted as a retrospective cohort study to investigate the relationship between AP in dental procedures and cardiac patients admitted in the surgical wards of KSUMC between 2015 and 2021. All cardiac patients who underwent dental procedures were included in the study. We excluded patients with long-term or concurrent antibiotic use for other indications. Results: Overall, 170 (69.4%) cardiac patients received AP before undergoing a dental procedure. The most common comorbidities were hypertension (39.1%) and diabetes (34.2%). Most of the low-risk (69.4%) and moderate-risk (70.5%) patients received AP, despite the guideline's recommendation to limit AP to high-risk patients only. Moreover, only 53.8% of high-risk patients were prescribed AP. In total, 95.9% of the 170 patients who received AP did so without following the recommendations. Only one patient developed IE during the 1-year follow-up. Tooth extraction was the only significant predictor of AP prescription in our study (P = 0.001; OR: 3.73; 95% CI; 1.678-8.298). Conclusion: There was an exceeding level of inconsistency (95.9%) in AP utilization by cardiac patients in our sample compared with the recommendations of the latest AHA guidelines.

ABSTRACT

Unexplained cardiac arrest (UCA) is a working diagnosis that should be replaced by a final diagnosis once evaluation is completed. Complete evaluation of UCA should include high-yield tests like cardiac magnetic resonance imaging, exercise treadmill test, and sodium-channel blocker challenge to identify latent causes of UCA. If no clear etiology is revealed after complete evaluation, idiopathic ventricular fibrillation may be diagnosed, and the strength of its diagnosis can be divided into definitive, probable, and possible based on the number of high-yield tests performed. Care should be provided by a multidisciplinary team with expertise in this area.

ABSTRACT

INTRODUCTION: The characteristics of young adults with out-of-hospital cardiac arrest (OHCA) due to acute coronary syndrome (ACS) has not been well described. The mean age of gulf citizens in ACS registries is 10-15 years younger than their western counterparts, which provided us with a unique opportunity to investigate the characteristics and predictors of OHCA in young adults presenting with ACS. METHODOLOGY: This was a retrospective cohort study using data from 7 prospective ACS registries in the Gulf region. In brief, all registries included consecutive adults who were admitted with ACS. OHCA was defined as cardiac arrest upon presentation (i.e., before admission to the hospital). We described the characteristics of young adults (< 50 years) who had OHCA and performed multivariate logistic regression analysis to assess independent predictors of OHCA. RESULTS: A total of 31,620 ACS patients were included in the study. There were 611 (1.93%) OHCA cases in the whole cohort [188/10,848 (1.73%) in young adults vs 423/20,772 (2.04%) in older adults, p = 0.06]. Young adults were predominantly males presenting with ST-elevation myocardial infarction (STEMI) [182/188 (96.8%) and 172/188 (91.49%), respectively]. OHCA was the sentinel event of coronary artery disease (CAD) in 70% of young adults. STEMI, male sex, and non-smoking status were found to be independent predictors of OHCA [OR = 5.862 (95% CI 2.623-13.096), OR: 4.515 (95% CI 1.085-18.786), and OR = 2.27 (95% CI 1.335-3.86), respectively]. CONCLUSION: We observed a lower prevalence of OHCA in ACS patients in our region as compared to previous literature from other regions. Moreover, OHCA was the sentinel event of CAD in the majority of young adults, who were predominantly males with STEMIs. These findings should help risk-stratify patients with ACS and inform further research into the characteristics of OHCA in young adults.

ABSTRACT

Sudden unexplained death (SUD) is a sudden, unexpected, and unexplained death in an individual older than 1 year. It is one of the most devastating and tragic events to families and the community at large, particularly when it happens at a young age. Finding the cause of SUD is extremely important in order to prevent its recurrence in the family, and to help understand the epidemiology of SUD in the community. It has been well-established that the most effective way of finding the cause of SUD is by performing a medical autopsy. In many countries, medical autopsy is mandated in SUD cases. In others, however, medical autopsy is rarely performed for the purpose of identifying the cause of SUD, which is the case in Saudi Arabia. In this review, we discussed the importance of finding the cause of death in SUD cases, the role of different types of medical autopsies, and the state of medical autopsy in Saudi Arabia. Moreover, we proposed a clinical pathway to incorporate medical autopsy in the care of SUD cases, and to connect family members to the health care system in order to perform cascade screening.

ABSTRACT

OBJECTIVES: To calculate the incidence of new-onset atrial fibrillation (NOAF) in myocardial infarction (MI) patients and examine associated predictors and clinical outcomes of NOAF patients. METHODS: A retrospective cohort study was used to carry out this study. All MI patients admitted to King Khaled University Hospital, Riyadh, Saudi Arabia, between January 2015 to 2020 were eligible for inclusion. The study excluded those with a previous diagnosis of atrial fibrillation and patients who died at presentation. RESULTS: A total of 281 patients were analyzed with a mean age of 58.7±12.7. Incidence of NOAF was 7.8%. Significant predictors identified by multivariate logistic regression analysis included older age (p=0.004), history of MI (p=0.012), and undergoing coronary artery bypass graft surgery (CABG) as treatment (p=0.016). New-onset atrial fibrillation was associated with higher odds of major adverse cardiovascular event (p=0.039), ventricular tachycardia (p=0.001), and mortality (p=0.031). CONCLUSION: New-onset atrial fibrillation is a relatively common complication of MI, and in our study, it was associated with higher odds of further complications including death. Therefore, identification of MI patients at risk of developing NOAF is crucial. Our study suggests that older age, a previous history of MI, and undergoing CABG are significant predictors of NOAF development.
