Ectopia cordis in an adult patient with COVID-19: A case report and literature review.

Ectopia cordis (EC) is a rare congenital condition characterized by a partial or complete defect of the anterior chest wall. It is associated with ventricular and atrial septal defects (ASD), Ebstein's anomaly, truncus arteriosus, transposition of the great vessels, tetralogy of Fallot, and hypoplastic left heart syndrome. This study aimed to explore the cardiac manifestations of EC complicated by coronavirus disease 2019 (COVID-19). A 23-year-old male, born with EC, was admitted to the hospital for acute cough and fever. The patient was diagnosed with EC and ASD by computed tomography and COVID-19 via a polymerase chain reaction swab test. Patients with ECs rarely survive till adulthood. However, due to the rarity of this syndrome, upon literature review, we did not find a case of EC with concurrent COVID-19 infection. The patient underwent the required investigations and conventional treatment such as fluid resuscitation, antibiotics administration, and full code cardiopulmonary resuscitation. The interventions performed were unsuccessful, and the patient died. This case demonstrates a patient who lived with EC and its associated cardiac anomalies but died of COVID-19 and its complications despite full resuscitation attempts. Our findings suggest that patients with EC may survive to adulthood if they have an incomplete EC, fewer intracardiac defects except for ASD, and an absence of an omphalocele.

Demographic, behavioral, and cardiovascular disease risk factors in the Saudi population: results from the Prospective Urban Rural Epidemiology study (PURE-Saudi).

BACKGROUND: Cardiovascular disease (CVD) is the major cause of death in Saudi Arabia. We aimed to assess associated demographic, behavioral, and CVD risk factors as part of the Prospective Urban Rural Epidemiology (PURE) study. METHODS: PURE is a global cohort study of adults ages 35-70 years in 20 countries. PURE-Saudi study participants were recruited from 19 urban and 6 rural communities randomly selected from the Central province (Riyadh and Alkharj) between February 2012 and January 2015. Data were stratified by age, sex, and urban vs rural and summarized as means and standard deviations for continuous variables and as numbers and percentages for categorical variables. Proportions and means were compared between men and women, among age groups, and between urban and rural areas, using Chi-square test and t-tests, respectively. RESULTS: The PURE-Saudi study enrolled 2047 participants (mean age, 46.5 ± 9.12 years; 43.1% women; 24.5% rural). Overall, 69.4% had low physical activity, 49.6% obesity, 34.4% unhealthy diet, 32.1% dyslipidemia, 30.3% hypertension, and 25.1% diabetes. In addition, 12.2% were current smokers, 15.4% self-reported feeling sad, 16.9% had a history of periods of stress, 6.8% had permanent stress, 1% had a history of stroke, 0.6% had heart failure, and 2.5% had coronary heart disease (CHD). Compared to women, men were more likely to be current smokers and have diabetes and a history of CHD. Women were more likely to be obese, have central obesity, self-report sadness, experience stress, feel permanent stress, and have low education. Compared to participants in urban areas, those in rural areas had higher rates of diabetes, obesity, and hypertension, and lower rates of unhealthy diet, self-reported sadness, stress (several periods), and permanent stress. Compared to middle-aged and older individuals, younger participants more commonly reported an unhealthy diet, permanent stress, and feeling sad. CONCLUSION: These results of the PURE-Saudi study revealed a high prevalence of unhealthy lifestyle and CVD risk factors in the adult Saudi population, with higher rates in rural vs urban areas. National public awareness programs and multi-faceted healthcare policy changes are urgently needed to reduce the future burden of CVD risk and mortality.

Waist-to-Height Ratio (WHtR) in Predicting Coronary Artery Disease Compared to Body Mass Index and Waist Circumference in a Single Center from Saudi Arabia.

This study aims to study the efficiency of the Waist-to-Height Ratio (WHtR) for determining coronary artery disease. It compares the frequency of abnormal WHtR, as a proxy for abdominal obesity, to that of body mass index (BMI) and waist circumference (WC). It also relates the findings to other cardiometabolic risk factors in University Hospital patients. A cross-sectional study design was used, where a sample of 200 patients (142 males and 58 females) who attended the adult cardiac clinic were purposively included. BMI, WC, and WHtR were measured, where frequencies of WHtR were compared to those of BMI and WC. The findings were related to the history of coronary artery disease (CAD) and history of cardiometabolic risk factors, including diabetes mellitus (DM), hypertension (HTN), and hyperlipidemia. Majority of the male patients were older, taller, and had a lower BMI value. It also showed that the prevalence of dyslipidemia and CAD was higher in male patients. No significant difference between both genders was noticed for weight, WC, WHtR, hypertension, or DM. BMI was least associated with high-risk cardiac population in both males and females (39.4% and 60.3%), followed by WC (84.5% and 96.6%, respectively). WHtR showed the highest association with gender (male 98.6% and females 98.3%). These findings were noticed in patients with all risk factors. WHtR is superior to BMI and WC for determining the elevated risk of diabetes, hypertension, dyslipidemia, and CAD in a single university institute. The role of WHtR in both normal and diseased Saudi population should be delineated.

Clinical Presentation, Quality of Care, Risk Factors and Outcomes in Women with Acute ST-Elevation Myocardial Infarction (STEMI): An Observational Report from Six Middle Eastern Countries.

BACKGROUND: Most of the available literature on ST-Elevated myocardial infarction (STEMI) in women was conducted in the developed world and data from Middle-East countries was limited. AIMS: To examine the clinical presentation, patient management, quality of care, risk factors and inhospital outcomes of women with acute STEMI compared with men using data from a large STEMI registry from the Middle East. METHODS: Data were derived from the third Gulf Registry of Acute Coronary Events (Gulf RACE-3Ps), a prospective, multinational study of adults with acute STEMI from 36 hospitals in 6 Middle-Eastern countries. The study included 2928 patients; 296 women (10.1%) and 2632 men (89.9%). Clinical presentations, management and in-hospital outcomes were compared between the 2 groups. RESULTS: Women were 10 years older and more likely to have diabetes mellitus, hypertension, and hyperlipidemia compared with men who were more likely to be smokers (all p<0.001). Women had longer median symptom-onset to emergency department (ED) arrival times (230 vs. 170 min, p<0.001) and ED to diagnostic ECG (8 vs. 6 min., p<0.001). When primary percutaneous coronary intervention (PPCI) was performed, women had longer door-to-balloon time (DBT) (86 vs. 73 min., p=0.009). When thrombolytic therapy was not administered, women were less likely to receive PPCI (69.7 vs. 76.7%, p=0.036). The mean duration of hospital stay was longer in women (6.03 ± 22.51 vs. 3.41 ± 19.45 days, p=0.032) and the crude in-hospital mortality rate was higher in women (10.4 vs. 5.2%, p<0.001). However, after adjustments, multivariate analysis revealed a statistically non-significant trend of higher inhospital mortality among women than men (6.4 vs. 4.6%), (p=0.145). CONCLUSION: Our study demonstrates that women in our region have almost double the mortality from STEMI compared with men. Although this can partially be explained by older age and higher risk profiles in women, however, correction of identified gaps in quality of care should be attempted to reduce the high morbidity and mortality of STEMI in our women.

Circadian Rhythm and ST-Segment Elevation Myocardial Infarction: Insights From the Third Gulf Registry of Acute Coronary Events (Gulf RACE-3Ps).

Circadian rhythms have been identified in multiple physiological processes that may affect cardiovascular diseases, yet little is known about the impact of circadian rhythm on acute ST-segment elevation myocardial infarction (STEMI) onset and outcomes in the Middle East. The relationship between time of symptom onset during the 24-hour circadian cycle and prehospital delays and in-hospital death was assessed in 2909 patients with STEMI presenting in 6 Arabian Gulf countries. A sinusoidal smoothing function was used to show the average circadian trends. There was a significant association between time of symptom onset and the circadian cycle. The STEMIs were more frequent during the late morning and early afternoon hours ( P < .001). Patients with pain onset from 0.00 to 5:59 had median prehospital delays of 150 minutes versus 90 minutes from 6:00 to 11:59 and 12:00 to 17:59, respectively ( P < .001). Although there was no significant difference in mortality between the 4 groups ( P = .230), there was a significant association between time of symptom onset as sinusoidal function and in-hospital mortality ( P = .032). Patients with STEMI in the Middle East have significant circadian patterns in symptoms onset, prehospital delay, and timeliness of reperfusion. A circadian rhythm of in-hospital mortality was found over the 24-hour clock of symptom onset time.

Clinical Presentation, Predictors, and Outcomes Among Mineralocorticoid Receptor Antagonist (MRA)-Eligible Acute Heart Failure Patients in the Heart Function Assessment Registry Trial in Saudi Arabia (HEARTS).

Mineralocorticoid receptor antagonist (MRA) therapy is indicated after myocardial infarction in patients with acute heart failure (AHF) with an ejection fraction ≤40% and lacking contraindications. We analyzed clinical presentations, predictors, and outcomes of MRA-eligible patients within a prospective registry of patients with AHF from 18 hospitals in Saudi Arabia, from 2009 to 2010. For this subgroup, mortality rates were followed until 2013, and the clinical characteristics, management, predictors, and outcomes were compared between MRA-treated and non-MRA-treated patients. Of 2609 patients with AHF, 387 (14.8%) were MRA eligible, of which 146 (37.7%) were prescribed MRAs. Compared with non-MRA-treated patients, those prescribed MRAs more commonly exhibited non-ST-segment elevation myocardial infarction, acute on chronic heart failure, past history of ischemic heart disease, and severe left ventricular systolic dysfunction; were more commonly administered oral furosemide and digoxin; and had higher in-hospital recurrent congestive HF rates. Mortality did not significantly differ ( P > .05) between groups. In Saudi Arabia, 37.7% of eligible patients received MRA treatment, which is higher than that in developed countries. The lack of long-term survival benefit raises concerns about systematic problems, for example, proper follow-up and management after hospital discharge, warranting further investigation.

Prevalence, awareness, treatment and control of hypertension in four Middle East countries.

OBJECTIVE: We report the prevalence, awareness, treatment, and control of hypertension across four Middle Eastern countries (Iran, Occupied Palestinian Territory, Saudi Arabia, and United Arab Emirates), using a standardized and uniform method. METHODS: The Prospective Urban Rural Epidemiology study enrolled participants from 52 urban and 35 rural communities from four countries in the Middle East. We report results using definitions of hypertension, prevalence, awareness, treatment, and control, and the standards for uniform reporting of hypertension in adults as recently recommended by the World Hypertension League expert committee. RESULTS: Data for analyses were available on 10 516 participants, of whom 5082 (48%) were men. The mean age was 49 (±9.4) years for men and 48 (±9.3) years among women. A total of 3270 participants had hypertension (age-standardized rates, 33%), and n = 1807 (49%) of these participants were aware of their diagnosis. Of those with hypertension, n = 1754, (47%) were treated and only n = 673, (19%) had controlled blood pressure levels. Only 17% (n = 541) of those treated for hypertension received two or more blood pressure-lowering medications and 15% (n = 499) received statins. The prevalence, awareness, treatment, and control of blood pressure were higher among women and older (50-69 years) participants compared with men and younger individuals (30-49 years) (P < 0.0001 for all). The prevalence was higher in rural communities; however, awareness, treatment, and control were significantly higher among urban dwellers. CONCLUSION: Findings from this study indicate the need for improvements in hypertension diagnosis and treatment in the Middle East, especially in rural communities, men and younger individuals.

Validation of the 6-Month GRACE Score in Predicting 1-Year Mortality of Patients With Acute Coronary Syndrome Admitted to the Arabian Gulf Hospitals.

Acute coronary syndromes (ACS) are the most common cardiovascular diseases and are associated with a significant risk of mortality and morbidity. The Global Registry of Acute Coronary Events (GRACE) risk score postdischarge is a widely used ACS prediction model for risk of mortality (low, intermediate, and high); however, it has not yet been validated in patients from the Arabian Gulf. This prospective multicenter study (second Gulf Registry of Acute Coronary Events) provides detailed information of the GRACE risk score postdischarge in patients from the Arabian Gulf. Its prognostic utility was validated at 1-year follow-up in over 5000 patients with ACS from 65 hospitals in 6 Arabian Gulf countries (Bahrain, Saudi Arabia, Qatar, Oman, United Arab Emirates, and Yemen). Overall, the goodness of fit (Hosmer and Lemeshow statistic P value = .826), calibration, and discrimination (area under the receiver operating characteristic curve = 0.695; 95% confidence interval: 0.668-0.722) were good. The GRACE risk score postdischarge can be used to stratify 1 year mortality risk in the Arabian Gulf population; it does not require further calibration and has a good discriminatory ability.

Pulmonary hypertension in Saudi Arabia: A single center experience.

CONTEXT: Several international studies have described the epidemiology of pulmonary hypertension (PH). However, information about the incidence and prevalence of PH in Saudi Arabia is unknown. AIMS: To report cases of PH and compare the demographic and clinical characteristics of PH due to various causes in a Saudi population. METHODS: Newly diagnosed cases of PH [defined as mean pulmonary artery pressure >25 mmHg at right heart cauterization (RHC)] were prospectively collected at a single tertiary care hospital from January 2009 and June 2012. Detailed demographic and clinical data were collected at the time of diagnosis, along with hemodynamic parameters. RESULTS: Of the total 264 patients who underwent RHC, 112 were identified as having PH. The mean age at diagnosis was 55.8 ± 15.8 years, and there was a female preponderance of 72.3%. About 88 (78.6%) of the PH patients were native Saudis and 24 (21.4%) had other origins. Twelve PH patients (10.7%) were classified in group 1 (pulmonary arterial hypertension), 7 (6.2%) in group 2 (PH due to left heart disease), 73 (65.2%) in group 3 (PH due to lung disease), 4 (3.6%) in group 4 (chronic thromboembolic PH), and 16 (14.3%) in group 5 (PH due to multifactorial mechanisms). PH associated with diastolic dysfunction was noted in 28.6% of group 2 patients, 31.5% of group 3 patients, and 25% of group 5 patients. CONCLUSIONS: These results offer the first report of incident cases of PH across five groups in Saudi Arabia.

Prediction of pulmonary hypertension in patients with or without interstitial lung disease: reliability of CT findings.

PURPOSE: To study the reliability of pulmonary vascular measurements based on computed tomography (CT) in the prediction of pulmonary hypertension (PH) in patients with advanced interstitial lung disease (ILD) compared with those without ILD. MATERIALS AND METHODS: The study was approved by the Institutional Review Board. All patients gave written informed consent. A prospective study of 134 patients who underwent right-sided heart catheterization and chest CT scanning within 72 hours of admission was conducted. Patients were divided into two groups-one with ILD (group A, n = 100) and one without ILD (group B, n = 34). CT measurements of the main pulmonary artery diameter (PAD), the ratio of PAD to the ascending aorta diameter (AAD), right pulmonary artery diameter (RPAD), and left pulmonary artery diameter (LPAD) were obtained. Univariate logistic regression analysis was performed, and receiver operating characteristic curves were constructed to assess the predictive ability of vascular measurements obtained by using CT in the identification of PH. RESULTS: Main PAD was significantly greater in patients with PH than in those without PH in both groups (group A, P = .008; group B, P = .02). A PAD greater than 25 mm in patients with ILD was predictive of PH, with a sensitivity of 86.4% (32 of 37), a specificity of 41.2% (26 of 63), a positive predictive value of 46.3% (32 of 69), and a negative predictive value of 83.8% (26 of 31). In patients without ILD, a PAD greater than 31.6 mm and an LPAD greater than 21.4 mm were predictive of PH (sensitivity, 47.3% [nine of 19]; specificity, 93.3% [14 of 15]; positive predictive value, 90.0% [nine of 10]; and negative predictive value, 58.3% [14 of 24]). CONCLUSION: CT-derived vascular measurements were of limited utility in the prediction of PH in patients with ILD compared with those without ILD.
