Publication Morbidity and mortality of acute heart failure patients stratified by mitral regurgitation in the Arabian Gulf: Observations from the Gulf acute heart failure registry (Gulf CARE)(2023) Alsheikh-Ali, Alawi A.Abstract: This study aimed to evaluate the clinical outcomes of patients with acute heart failure (AHF) stratified by mitral regurgitation (MR) in the Arabian Gulf. Patients from the Gulf CARE registry were identified from 47 hospitals in seven Arabian Gulf countries (Yemen, Oman, Kuwait, Qatar, Bahrain, the United Arab Emirates, and Saudi Arabia) from February to November 2012. The cohort was stratified into two groups based on the presence of MR. Univariable and multivariable statistical analyses were performed. The population cohort included 5005 consecutive patients presenting with AHF, of whom 1491 (29.8 %) had concomitant MR. The mean age of patients with AHF and concomitant MR was 59.2 ± 14.9 years, and 63.1 % (n = 2886) were male. A total of 58.6 % (n = 2683) had heart failure (HF) with reduced ejection fraction (EF) (HFrEF), 21.0 % (n = 961) had HF with mildly reduced EF (HFmrEF), and 20.4 % (n = 932) had HF with preserved EF (HFpEF). Patients with MR had a lower haemoglobin (Hb) level (12.4 vs. 12.7 g/dL; p < 0.001), and a higher prevalence of left atrial enlargement (80.2 % vs. 55.1 %; p < 0.001), cardiogenic shock (9.7 % vs. 7.3 %; p = 0.006) and atrial fibrillation (7.6 % vs. 5.6 %; p = 0.006), and HFrEF (71.0 % vs. 52.6 %; P < 0.001). Multivariable analysis demonstrated that MR was independently associated with increased all-cause mortality at 1-year and 3-month HF rehospitalization [1-year all-cause mortality, adjusted odds ratio (aOR), 1.40; 95 % confidence interval (Cl): 1.13–1.74; p = 0.002; 3-month HF rehospitalization, aOR, 1.26; 95 % Cl: 1.06–1.49; p = 0.009]. In an Arabian Gulf cohort with AHF, concomitant MR was associated with an increased risk of 1-year mortality and 3-months HF rehospitalization.Publication Ventricular Arrhythmias in Patients with Spontaneous Coronary Artery Dissection(2020) Alsheikh-Ali, Alawi A.Background: Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute coronary syndrome in young women, with a wide clinical spectrum of severity. Ventricular arrhythmia (VA) can occur and worsen prognosis. The current study compared in-hospital and follow-up adverse cardiovascular events in patients with and without VA at presentation. Methods: Eighty-three cases of SCAD were collected retrospectively from 4 Gulf countries (KSA, UAE, Kuwait, and Bahrain) during the period from January 2011 to December 2017. We divided the patients into 2 groups: those with and without VA at presentation. VA was defined as ventricular tachycardia and/or ventricular fibrillation. In-hospital (recurrent VA, cardiogenic shock, death, implantable cardioverter-defibrillator placement, dissection extension) and follow-up (MI, de novo SCAD, death, spontaneous superior mesenteric artery dissection) events were compared among the 2 groups. Results: The median age of patients in the study was 44 (37–55) years. Fortytwo (51%) were women. VA occurred in 10 (12%) patients in the first 24-hour of hospitalization, and 5 (50%) of those patients had recurrent in-hospital VA. Among those with recurrent VA, 1 died during hospitalization and 1 died within the first year following hospital discharge. Conclusions: In-hospital adverse cardiovascular events were significantly more frequent for patients with SCAD who presented with VA. However, follow-up events were not statistically significant between those with and without VA at presentation.
