Saudi Heart Association, National Heart Center and National Cardiopulmonary Resuscitation Committee taskforce statement on CPR and resuscitation during COVID-19 pandemic.

Corona virus disease 2019 is a global pandemic, which affects around 2million individuals with a high death rate that exceeds 90,000 death cases across the globe. The Saudi Heart Association and the national cardiopulmonary resuscitation committee developed a taskforce to discuss the magnitude of clinical situation and CPR management on COVID-19 patients in a prehospital and in-hospital settings. Meanwhile, the taskforce aims to develop a nation-wide clinical guidance to be used by health care workers and untrained laypersons to resuscitate COVID-19 suspected and diagnosed patients.

Food and Migration: Dietary Acculturation among Migrants to the Kingdom of Saudi Arabia.

METHODS: A cross sectional study design was used based on 2 questionnaires; Rosenmoller et al's and the WHO STEPS surveillance tool for chronic disease surveillance. Data on length of residency, dietary patterns, anthropometric and biochemical measurements were collected by trained interviewers. Descriptive statistics were reported as a percentage or mean, as appropriate. Chi-square test, Fisher's exact test or independent t test, Univariate and Multivariate logistic regression analysis were used to compare the significance between variables. RESULTS: Both male and female participants showed a similar mean age (39.7 and 38.5 years). Approximately 61% of them had <5 year's duration of residency. Significant gender differences were observed in blood pressure and biochemical measurements, with men showing higher mean systolic and diastolic blood pressure and dyslipidemia than women (P < .001). Women had significantly higher BMI (P < .001), showed higher mean food practice (P < .001) and awareness scores than men. CONCLUSIONS: Migration into Saudi Arabia from this subgroup showed marked changes in the food practice; acquisition of unhealthy dietary practices also co-existed despite improved awareness and the presence of comorbidities. Findings from this study have relevance to other migrant communities and public health policy.

Performance of neck circumference to predict obesity and metabolic syndrome among adult Saudis: a cross-sectional study.

BACKGROUND: Neck circumference (NC) is a novel simple and stable body measurement, a growing body of evidence indicates its validity to diagnose obesity and metabolic syndrome (MetS). Because the cutoff value of NC is gender and ethnic-specific; we conducted the current study to explore the performance of NC to predict general obesity, central obesity, and MetS among adult Saudis of both genders. METHODS: This is a cross-sectional study which included 3063 adult Saudis (1156 males and 1907 females) with a mean age of 38.6 ± 14.1 years. Anthropometric measurements and blood pressure were assessed by a standardized methodology. Blood tests including fasting lipid panel, blood glucose, fasting blood glucose and hemoglobin A1c (HBA1c) were measured for all participants. We identified the MetS based on Adult Treatment Panel III (ATPIII definition). Data were analyzed using SPSS®19 (PASW statistics data document 19); NC was compared to relevant anthropometric measures to predict obesity and MetS using Receiver Operator Characteristic (ROC) analyses. The cutoff value of NC which possessed good discriminating power between obese and non-obese patients was estimated by Youden index, and we estimated the adjusted Odds Ratio (OR) to delineate the association between NC and the outcome variables by multiple logistic regression analysis. RESULTS: ROC analyses demonstrated good performance of NC for general obesity, central obesity and MetS; as a predictor of obesity in non-diabetics, Area Under the Curve (AUC) ranged from 0.77-0.86. In MetS, AUC was 0.77 and 0.82 for males and females respectively. The best cutoff values of the NC to predict obesity were ≥ 37.5 cm for males versus ≥32.5 cm for females. The results of adjusted logistic regression analysis adjusted for age and waist height ratio, revealed a consistent positive association between NC, general obesity, MetS, and central obesity: ORs were 4.26, 3.03, 1.45 for males versus 4.65, 3.66, and1.47 for females respectively. CONCLUSION: NC stands out as an independent predictor of obesity and the MetS. Its stability, easiness of application, low cost and the cultural acceptance, justify its use as a screening tool for general and central obesity as well as MetS among Saudis under community settings, and as an additional routine measurement for health professionals.

Baseline characteristics, management practices, and long-term outcomes among patients with first presentation acute myocardial infarction in the Second Gulf Registry of Acute Coronary Events (Gulf RACE-II).

BACKGROUND AND OBJECTIVES: Limited data are available highlighting the different clinical aspects of acute coronary syndrome (ACS) patients, especially in Gulf countries. In this study, we aimed to compare patients who presented with acute myocardial infarction (AMI) as the first presentation of patients who have a history of ACS in terms of initial presentation, medical history, laboratory findings, and overall mortality. METHODS: We used the Second Gulf Registry of Acute Coronary Events (Gulf RACE-II), which is a multinational observational study of 7930 ACS patients. RESULTS: Among all patients, 4723 (59.6%) patients presented with AMI. First presentation AMI patients were older (mean age, 55 years vs. 53 years; p < 0.001) and had lower risk factors than patients with a history of ACS. Higher laboratory readings of cardiac markers and all aspects of mortality were significantly higher among patients with first presentation AMI. After adjustments for baseline variables, congestive heart failure [odds ratio (OR) = 1.08; 95% confidence interval (CI), 0.73-1.57], reinfarction (OR = 1.16; 95% CI, 0.58-2.30), cardiogenic shock (OR = 1.51; 95% CI, 0.74-3.08), stroke (OR = 2.30; 95% CI, 0.29-17.99), and overall mortality (OR = 1.16; 95% CI = 0.74-1.83) were independent predictive factors for first presentation AMI. CONCLUSIONS: First presentation AMI patients tend to be older and to have lower rates of risk factors. Adverse clinical outcomes such as congestive heart failure, reinfarction, cardiogenic shock, and stroke were higher among patients with first presentation AMI compared to patients with a history of ACS.

Clinical profile and mutation spectrum of long QT syndrome in Saudi Arabia: The impact of consanguinity.

BACKGROUND: Congenital long QT syndrome (LQTS) is an inherited, potentially fatal arrhythmogenic disorder. At least 16 genes have been implicated in LQTS; the yield of genetic analysis of 3 genes (KCNQ1, KCNH2, and SCN5A) is about 70%, with KCNQ1 mutations accounting for ∼50% of positive cases. LQTS is mostly inherited in an autosomal dominant pattern. Systemic analysis of LQTS has not been previously conducted in a population with a high degree of consanguinity. OBJECTIVES: To describe the clinical and molecular profiles of LQTS in the highly consanguineous Saudi population. METHODS: Fifty-six Saudi families with LQTS were consecutively recruited and evaluated. Sequencing of KCNQ1, KCNH2, and SCN5A genes was conducted on all probands, followed by screening of family relatives. RESULTS: Genetic analysis was positive in 32 (57.2%) families, with mutations in KCNQ1 identified in 28 families (50%). Surprisingly, 17 (53.1%) probands were segregating homozygous mutations. Family screening identified 123 individuals with mutations; 89 (72.4%) were heterozygous, 23 (18.7%) were homozygous, and 11 (8.9%) were compound heterozygous. Compared to heterozygous, the phenotype was more severe in homozygous individuals, with cardiac symptoms in 78.3% (vs 12.4%), family history of sudden death in 64.7% (vs 44.4%), and prolonged QT interval in 100% (vs 43.8%). Congenital deafness was found in 11 (47.8%) homozygous probands. CONCLUSION: Our study provides insight into the clinical and molecular profiles of LQTS in a consanguineous population. It underscores the importance of preemptive management in homozygous patients with LQTS and the value of clinical and molecular screening of at-risk relatives.

Diagnostic yield and therapeutic impact of transthoracic echocardiography in patients with potential cardiac sources of cerebral embolism.

OBJECTIVE: To explore the diagnostic yield of transthoracic echocardiography (TTE), and assess the effect of echocardiographic findings on subsequent therapy. METHODS: In this retrospective study, we reviewed TTE reports and hospital records of patients diagnosed with a stroke or transient ischemic attack (TIA), screening for potential cardiac sources of embolism (CSE) from January 2006 to December 2008 at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia by considering at least 15 predefined TTE criteria. The therapeutic interventions employed as a consequence of the TTE findings were sought. RESULTS: We analyzed 240 patients (mean patient age 58.514) out of 10563 TTEs. While only one patient exhibited a definite CSE on TTE, potential CSEs were found in 35 patients (14.6%), most commonly caused by left ventricular (LV) systolic dysfunction (31.4%), followed by LV regional wall motion abnormalities (25.7%). Multivariate analysis revealed 2 independent predictors for identifying a CSE on TTE: history of coronary artery disease (odds ratio [OR] 6.2, 95% confidence interval [CI]:2.6-14.8, p=0.0001), and nationality (OR 0.16, 95% CI: 0.3-0.7, p=0.019). The TTE findings affected therapy in only 3 patients (1.2%). CONCLUSION: The TTE performed to exclude a CSE in patients with stroke or TIA resulted in low diagnostic yield, and had little impact on therapeutic decisions. Future refinement of clinical strategies to predict a CSE is needed to improve diagnosis, and possibly cost-effectiveness, of TTE.
