RESUMO
This study is done to estimаte in-hоsÑitаl mоrtаlity in Ñаtients with severe аÑute resÑirаtоry syndrоme Ñоrоnаvirus 2 (SÐRS-СоV-2) strаtified by Vitamin-D (Vit-D) levels. Раtients were strаtified аÑÑоrding tо by serum 25-hydroxy-vitamin D (25(OH)Vit-D) levels intо twо grоuÑs, that is, 25(OH)Vit-D less thаn 40 nmol/L аnd 25(OH)Vit-D greаter thаn 40 nmol/L. Ð tоtаl оf 231 Ñаtients were inÑluded. Ðf these, 120 (50.2%) оf the Ñаtients hаd 25(OH)Vit-D levels greаter thаn 40 nmol/L. The meаn аge wаs 49 ± 17 yeаrs, аnd 67% оf the Ñаtients were mаles. The mediаn length оf оverаll hоsÑitаl stаy wаs 18 [6; 53] dаys. The remаining 119 (49.8%) Ñаtients hаd а 25(OH)Vit-D less thаn 40 nmol/L. Vitamin D levels were seen as deficient in 63% of patients, insufficient in 25% and normal in 12%. Ðverаll mоrtаlity wаs 17 Ñаtients (7.1%) but statistically not signifiÑаnt among the grоuÑs (p = 0.986). The KаÑlаn-Meier survivаl аnаlysis shоwed no significance based on an alpha of 0.05, LL = 0.36, df = 1, p = 0.548, indicating Vitamin_D_Levels was not able to adequately predict the hazard of Mortality. In this study, serum 25(OH)Vit-D levels were found have no significance in terms of predicting the in-hоsÑitаl mortality in Ñаtients with SÐRS-СоV-2.

OBJECTIVES: To assess the effectiveness and safety of tocilizumab, a humanised anti-interleukin-6 receptor antibody, in the treatment of critical or severe coronavirus disease 2019 (COVID-19) patients. METHODS: This was a retrospective cohort study of severe or critical COVID-19 patients (≥18 years) admitted to one hospital in Kuwait. Fifty-one patients received intravenous tocilizumab, while 78 patients received the standard of care at the same hospital. Both groups were compared for clinical improvement and in-hospital mortality. RESULTS: The tocilizumab (TCZ) group had a significantly lower 28-day in-hospital mortality rate than the standard-of care-group (21.6% vs. 42.3% respectively; p = 0.015). Fifty-five per cent of patients in the TCZ group clinically improved vs. 11.5% in the standard-of-care group (p < 0.001). Using Cox-proportional regression analysis, TCZ treatment was associated with a reduced risk of mortality (adjusted hazard ratio 0.25; 95% CI: 0.11-0.61) and increased likelihood of clinical improvement (adjusted hazard ratio 4.94; 95% CI: 2.03-12.0), compared to the standard of care. The median C-reactive protein, D-dimer, procalcitonin, lactate dehydrogenase and ferritin levels in the tocilizumab group decreased significantly over the 14 days of follow-up. Secondary infections occurred in 19.6% of the TCZ group, and in 20.5% of the standard-of-care group, with no statistical significance (p = 0.900). CONCLUSION: Tocilizumab was significantly associated with better survival and greater clinical improvement in severe or critical COVID-19 patients.

OBJECTIVE: Despite the expanding burden of heart failure (HF) worldwide, data on HF precipitating factors (PFs) in developing countries, particularly the Middle East, are very limited. We examined PFs in patients hospitalized with acute HF in a prospective multicenter HF registry from 7 countries in the Middle East. METHOD: Data were derived from the Gulf CARE (Gulf aCute heArt failuRe rEgistry) for a prospective, multinational, multicenter study of consecutive patients hospitalized with HF in 47 hospitals in 7 Middle Eastern countries between February 2012 and November 2012. PFs were determined by the treating physician from a predefined list at the time of hospitalization. RESULTS: The study included 5,005 patients hospitalized with acute HF, 2,276 of whom (45.5%) were hospitalized with acute new-onset HF (NOHF) and 2,729 of whom (54.5%) had acute decompensated chronic HF (DCHF). PFs were identified in 4,319 patients (86.3%). The most common PF in the NOHF group was acute coronary syndromes (ACS) (39.2%). In the DCHF group, it was noncompliance with medications (27.8%). Overall, noncompliance with medications was associated with a lower inhospital mortality (OR 0.47; 95% CI 0.28-0.80; p = 0.005) but a higher 1-year mortality (OR 1.43; 95% CI 1.1-1.85; p = 0.007). ACS was associated with higher inhospital mortality (OR 1.84; 95% CI 1.26-2.68; p = 0.002) and higher 1-year mortality (OR 1.62; 95% CI 1.27-2.06; p = 0.001). CONCLUSION: Preventive and therapeutic interventions specifically directed at noncompliance with medications and ACS are warranted in our region.

BACKGROUND: Isolation of infract related artery and timely revascularisation remains vital in the setting of primary percutaneous coronary intervention. OBJECTIVES: To analyse the predictive value of ST-T changes in lead aVR in inferior myocardial infarction in terms of prognosis and timely risk stratification. METHODS: We conducted a prospective analysis of acute inferior wall myocardial infarction patients. One hundred patients were categorised into two groups according to the culprit artery: group I, right coronary artery (RCA) and group II, left circumflex coronary artery (LCX), with 50 patients in each group. A comparative study was performed between the two groups, comprising the following data outputs: electrocardiogram (ECG) changes that could help determine the culprit artery, cardiac enzyme levels, echocardiographic findings, coronary angiography findings and in-hospital complications. The same patients were divided into two groups according to the presence or absence of 1â¯mm ST depression in lead aVR. A comparison analysis was performed between the two groups including: cardiac enzyme levels, echocardiographic findings, coronary angiography findings and in-hospital complications. RESULTS: ST depression in aVRâ¯≥â¯1â¯mm predicted the LCX as a culprit artery with sensitivity, specificity, positive predictive values (PPV) and negative predictive values (NPV) recorded at 66%, 84%, 80.5% and 71.2%, respectively. Also, patients with ST depression in aVRâ¯≥â¯1â¯mm showed significantly higher cardiac enzyme levels, indicating larger infarct size, with mean peak creatinine kinase (CK)â¯=â¯1560 (1057-2375) IU/L versus 970 (613-1683) IU/L, (P valueâ¯=â¯0.014), lower ejection fraction (Ef) with mean Efâ¯=â¯47.93⯱â¯8.04 versus 54.66⯱â¯6.52, (P valueâ¯<â¯0.001) and more significant mitral regurgitation: 17 (41.5%) patients versus 11 (18.6%) patients (P valueâ¯=â¯0.012). Regarding in-hospital complications, there were no significant differences. CONCLUSIONS: ST depression of >1â¯mm in lead aVR predicts LCX as the infarct related artery and is a predictor of poor outcome in patients with inferior myocardial infarction.

Background: Chronic kidney disease (CKD) is a common comorbid condition in patients undergoing transcatheter aortic valve replacement (TAVR). Reported outcome studies on the association of baseline CKD and mortality is currently limited. Objectives: To determine the prevalence of chronic kidney disease in patients undergoing TAVR and analyse their overall procedural outcomes. Methods: This retrospective observational study was conducted at 43 publicly funded hospitals in Hong Kong. Severe aortic stenosis patients undergoing TAVR between the years 2010 and 2019 were enroled in the study. Two groups were identified according to the presence of baseline chronic kidney disease. Results: A total of 499 patients (228, 58.6% men) were enroled in the study. Baseline hypertension was more prevalent in patients with CKD (82.8%; P=0.003). As for primary end-points, mortality rates of CKD patients were significantly higher compared to non-CKD patients (10% vs. 4.1%; P=0.04%). Gout and hypertension were found to be significantly associated with CRF. Patients with gout were nearly six times more likely to have CRF than those without gout (odds ratio = 5.96, 95% CI = 3.12-11.29, P<0.001). Patients with hypertension had three times the likelihood of having CRF compared to those without hypertension (odds ratio=2.83, 95% CI=1.45-6.08, P=0.004). Conclusion: In patients with severe aortic stenosis undergoing TAVR, baseline CKD significantly contributes to mortality outcomes at long-term follow up.
RESUMO
We report a rare case of arrhythmogenic right ventricular cardiomyopathy (ARVC). Middle-aged Kuwaiti gentleman presented to a polyclinic with complaints of dizziness and palpitation. Electrocardiogram (ECG) at the polyclinic showed polymorphic ventricular tachycardia, and hence he was referred to our center. ECG at the emergency room showed a Brugada pattern with epsilon waves. Echo showed right ventricular dysfunction with pulmonary arterial hypertension. Magnetic resonance imaging showed evidence of ARVC. He was referred to the electrophysiology team and implanted an implantable cardioverter-defibrillator electively.
RESUMO
Objectives: The Rajan's heart failure (R-hf) score was proposed to aid risk stratification in heart failure patients. The aim of this study was to validate R-hf risk score in patients with acute decompensated heart failure. Methods: R-hf risk score is derived from the product estimated glomerular filtration rate (mL/min), left ventricular ejection fraction (%), and hemoglobin levels (g/dL) divided by N-terminal pro-brain natriuretic peptide (pg/mL). This was a multinational, multicenter, prospective registry of heart failure from seven countries in the Middle East. Univariable and multivariable logistic regression was applied. Results: A total of 776 patients (mean age = 62.0±14.0 years, 62.4% males; mean left ventricular ejection fraction = 33.0±14.0%) were included. Of these, 459 (59.1%) presented with acute decompensated chronic heart failure. The R-hf risk score group (≤ 5) was marginally associated with a higher risk of all-cause cumulative mortality at three months (adjusted odds ratio (aOR) = 4.28; 95% CI: 0.90-20.30; p =0.067) and significantly at 12 months (aOR = 3.84; 95% CI: 1.23-12.00; p =0.021) when compared to those with the highest R score group (≥ 50). Conclusions: Lower R-hf risk scores are associated with increased risk of all-cause cumulative mortality at three and 12 months.
RESUMO
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.
RESUMO
ABSTRACT: This study aimed to report on the use, predictors and outcomes of guideline-based medical therapy (GBMT) in patients with acute heart failure (HF) with reduced ejection fraction of <40% (HFrEF), from seven countries in the Arabian Gulf.Patients with acute HFrEF (Nâ=â2680), aged 18âyears or older, and hospitalized February-November 2012 were recruited and data were collected post discharge at 3âmonths (nâ=â2477) and 1âyear (nâ=â2418). The use and doses of GBMT were evaluated as per European, American and Canadian HF guidelines. Analyses were performed using multivariate logistic regression. This study was registered at clinicaltrials.gov (NCT01467973).The majority of patients were on dual (39%) and triple (39%) GBMT modalities, 14% received one GBMT medication, while 7.2% were not on any GBMT medications. On admission, 80% of patients were on renin-angiotensin system (RAS) blockers, 75% on b-blockers and 56% on mineralocorticoid receptor antagonists (MRAs), with a small proportion of these patients were taking target doses (RAS blockers 13%, b-blockers 7.3%, MRAs 14%). Patients taking triple GBMT were younger (Pâ<â.001), less likely to have comorbidities such as diabetes mellitus (Pâ<â.001) and CKD/dialysis (Pâ<â.001), less likely to receive in-hospital invasive treatments (Pâ<â.001), and more likely to be treated by a cardiologist (Pâ<â.001), than patients on a single medication. Patients taking triple GBMT showed significantly reduced all-cause mortality both at 3-months (Pâ=â.048), and at 12-months (Pâ=â.003), compared to patients taking no GBMT.Triple GBMT prescribing and dosing in patients with HFrEF were suboptimal in the Arabian Gulf. Further studies are required to investigate GBMT utilization and dosing in the outpatient setting.

Background: The aim of this study was to determine in-hospital mortality in patients presenting with severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) and to evaluate for any differences in outcome according to sex differences. Methods: Patients with SRS-CoV-2 infection were recruited into this retrospective cohort study between February 26 and September 8, 2020 and strаtified аÑÑоrding tо the sex differences. Results: In tоtаl оf 3360 Ñаtients (meаn аge 44 ± 17 years) were included, of whom 2221 (66%) were mаle. The average length of hospitalization was 13 days (range: 2-31 days). During hospitalization and follow-up 176 patients (5.24%) died. In-hospital mortality rates were significantly different according to gender (p=<0.001). Specifically, male gender was associated with significantly greater mortality when compared to female gender with results significant at an alpha of 0.05, LL = 28.67, df = 1, p = 0.001, suggesting that gender could reliably determine mortality rates. The coefficient for the males was significant, B = 1.02, SE = 0.21, HR = 2.78, p < 0.001, indicating that an observation in the male category will have a hazard 2.78 times greater than that in the female category. Multivariate logistic regression confirmed male patients admitted with SARS-CoV-2had higher Ñumulаtive аll-Ñаuse in-hоsÑitаl mоrtаlity (6.8% vs. 2.3%; аdjusted оdds rаtiо (аÐR), 2.80; 95% (СI): [1.61-5.03]; Ñ < 0.001). Conclusions: Male gender was an independent predictor of in-hospital mortality in this study. The mortality rate among male SARS-CoV-2 patients was 2.8 times higher when compared with females.
RESUMO
The goal of this study was to investigate in-hospital mortality in patients suffering from acute respiratory syndrome coronavirus 2 (SARS-CoV-2) relative to the neutrophil to lymphocyte ratio (NLR) and to determine if there are gender disparities in outcome. Between February 26 and September 8, 2020, patients having SARS-CoV-2 infection were enrolled in this retrospective cohort research, which was categorized by NLR levels ≥9 and < 9. In total, 6893 patients were involved included of whom6591 had NLR <9, and 302 had NLR ≥9. The age of most of the patients in the NLR<9 group was 50 years, on the other hand, the age of most of the NLR ≥9 group patients was between 50 and 70 years. The majority of patients in both groups were male 2211 (66.1%). The ICU admission time and mortality rate for the patients with NLR ≥9 was significantly higher compared to patients with NLR <9. Logistic regression's outcome indicated that NLR ≥9 (odds ratio (OR), 24.9; 95% confidence interval (CI): 15.5-40.0; p < 0.001), male sex (OR, 3.5; 95% CI: 2.0-5.9; p < 0.001) and haemoglobin (HB) (OR, 0.95; 95% CI; 0.94-0.96; p < 0.001) predicted in-hospital mortality significantly. Additionally, Cox proportional hazards analysis (B = 4.04, SE = 0.18, HR = 56.89, p < 0.001) and Kaplan-Meier survival probability plots also indicated that NLR>9 had a significant effect on mortality. NLR ≥9 is an independent predictor of mortality(in-hospital) among SARS-CoV-2 patients.
RESUMO
Objectives: Initial reports indicate a high incidence of abnormal aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in patients with COVID-19 and possible association with acute kidney injury (AKI). We aimed to investigate clinical features of elevated transaminases on admission, its association with AKI, and outcomes in patients with COVID-19. Methods: A retrospective analysis of the registered data of hospitalized patients with laboratory-confirmed COVID-19 and assessment of the AST and ALT was performed. Multinomial logistic regression was used to determine factors associated with community-acquired AKI (CA-AKI) and hospital-acquired AKI (HA-AKI). Results: The subjects comprised 828 patients (mean age = 65.0±16.0 years; 51.4% male). Hypertension was present in 70.3% of patients, diabetes mellitus in 26.0%, and chronic kidney disease in 8.5%. In-hospital mortality was 21.0%. At admission, only 41.5% of patients had hypertransaminasemia. Patients with elevated transaminases at admission were younger, had higher levels of inflammatory markers and D-dimer, and poorer outcomes. The AKI incidence in the study population was 27.1%. Patients with hypertransaminasemia were more likely to develop AKI (33.5% vs. 23.3%, p = 0.003). Patients with predominantly elevated AST (compared to elevated ALT) were more likely to have adverse outcomes. Multinomial logistic regression found that hypertension, chronic kidney disease, elevated AST, and hematuria were associated with CA-AKI. Meanwhile, age > 65 years, hypertension, malignancy, elevated AST, and hematuria were predictors of HA-AKI. Conclusions: Elevated transaminases on admission were associated with AKI and poor outcomes. Patients with elevated AST were more likely to have adverse outcomes. Elevated AST on admission was associated with CA-AKI and was a predictor of HA-AKI.
RESUMO
Background: The aim of this study was to validate R-heart failure (R-hf) risk score in ischemic heart failure patients. Methods: We prospectively recruited a cohort of 179 ischemic and 107 non-ischemic heart failure patients. This study mainly focused on ischemic heart failure patients. Non-ischemic heart failure patients were included for the purpose of validation of the risk score in various heart failure groups. Patients were stratified in high risk, moderate risk and low risk groups according to R-hf risk score. Results: A total of 179 participants with ischemic heart failure were included. Based on R-hf risk score, 82 had high risk, 50 had moderate risk and 47 had low risk heart failure scores. More than half of the patients having R-hf score of <5 had renal failure (n = 91, 50.8%) and anemia (n = 99, 55.3%). Notably, HFrEF was more prevalent in patients with high risk score (74, 90.2%). Patients with high risk score had significantly higher creatinine (2.63 ± 1.96, p < 0.001), Troponin-T HS (59.9 ± 38.0, p < 0.001) and PRO BNP (17842 ± 6684, p < 0.001) when compared to patients with low and moderate risk score. Patients with low risk score had significantly higher Hb (13.2 ± 1.85, p < 0.001), Albumin (3.69 ± 0.42, p < 0.001) and GFR (90.0 ± 8.04, p < 0.001). A R-hf score of <5 was a significant predictor of mortality in ischemic (OR = 50.34; 95% CI [16.94-194.00, p < 0.001) and non-ischemic (OR = 46.34; 95% CI [12.97-225.39], p < 0.001) heart failure patients. Conclusions: Lower R-hf risk score is a significant predictor of mortality in ischemic and non-ischemic heart failure patients. Risk score can be accessed at https://www.hfriskcalc.in.
RESUMO
Introduction: To define baseline echocardiographic, electrocardiographic (ECG) and computed tomographic (CT) findings of patients with heart failure undergoing transcatheter aortic valve replacement (TAVR) and analyze their overall procedural outcomes. Methods: Between 2018 and 2021, patients with severe aortic stenosis (AS) who performed transcatheter aortic valve replacement (TAVR) in Sabah Al Ahmad Cardiac Centre, Al Amiri Hospital were identified. A retrospective review of patients' parameters including pre-, intra-, and post-procedural data was conducted. Patients were grouped in 2 subgroups according to their EF: EF <40% (HFrEF) and EF ≥ 40%. The data included patients' baseline characteristics, electrocardiographic and echocardiographic details along with pre-procedural CT assessment of aortic valve dimensions. Primary outcomes including post-operative disturbances, pacemaker implantation and in-hospital mortality following TAVR were additionally analyzed. Results: A total of 61 patients with severe AS underwent TAVR. The mean age was 73.5 ± 9, and 21 (34%) of the patients were males. The mean ejection fraction (EF) was 55.5 ± 9.7%. Of 61 patients, 12 (20%) were identified as heart failure with reduced EF (<40%). These patients were younger, more often males, and were more likely to have coronary artery disease (75% versus 53.1%). Left ventricular hypertrophy and diastolic dysfunction was documented in 75% and 58.3% of patients with heart failure with reduced ejection fraction (HFrEF) respectively. Post TAVR conduction disturbances, with the commonest being LBBB was observed in 41.7%. Permanent pacemaker was implanted in 3 of patients with HFrEF (25%). There were no significant differences between the two groups with regards to in hospital mortality (p = 0.618). Conclusion: Severe AS with EF <40% constitute a remarkable proportion of patients undergoing TAVR. Preliminary results of post-operative conduction disturbances and in hospital mortality in HFrEF patients were concluded to not differ from patients with LVEF ≥40%.
RESUMO
This study is to estimate in-hospital mortality in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patients stratified by hemoglobin (Hb) level. Patients were stratified according to hemoglobin level into two groups, that is, Hb <100 g/L and Hb >100 g/L. A total of 6931 patients were included. Of these, 6377 (92%) patients had hemoglobin levels >100 g/L. The mean age was 44 ± 17 years, and 66% of the patients were males. The median length of overall hospital stay was 13 days [2; 31]. The remaining 554 (8%) patients had a hemoglobin level <100 g/L. Overall mortality was 176 patients (2.54%) but was significantly higher in the group with hemoglobin levels <100 g/L (124, 22.4%) than in the group with hemoglobin levels >100 g/L (52, 0.82%). Risk factors associated with increased mortality were determined by multivariate analysis. The Kaplan-Meier survival analysis showed hemoglobin as a predictor of mortality. Cox proportional hazards regression coefficients for hemoglobin for the HB ≤ 100 category of hemoglobin were significant, B = 2.79, SE = 0.17, and HR = 16.34, p < 0.001. Multivariate logistic regression showed Hb < 100 g/L had a higher cumulative all-cause in-hospital mortality (22.4% vs. 0.8%; adjusted odds ratio [aOR], 0.33; 95% [CI]: [0.20-0.55]; p < 0.001). In this study, hemoglobin levels <100 g/L were found to be an independent predictor of in-hospital mortality.
RESUMO
BACKGROUND AND AIMS: Familial hypercholesterolemia (FH) is a common autosomal dominant disorder that can result in premature atherosclerotic cardiovascular disease (ASCVD). Limited data are available worldwide about the prevalence and management of FH. Here, we aimed to estimate the prevalence and management of patients with FH in five Arabian Gulf countries (Saudi Arabia, Oman, United Arab Emirates, Kuwait, and Bahrain). METHODS: The multicentre, multinational Gulf FH registry included adults (≥18 years old) recruited from outpatient clinics in 14 tertiary-care centres across five Arabian Gulf countries over the last five years. The Gulf FH registry had four phases: 1- screening, 2- classification based on the Dutch Lipid Clinic Network, 3- genetic testing, and 4- follow-up. RESULTS: Among 34,366 screened patient records, 3713 patients had suspected FH (mean age: 49±15 years; 52% women) and 306 patients had definite or probable FH. Thus, the estimated FH prevalence was 0.9% (1:112). Treatments included high-intensity statin therapy (34%), ezetimibe (10%), and proprotein convertase subtilisin/kexin type 9 inhibitors (0.4%). Targets for low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol were achieved by 12% and 30%, respectively, of patients at high ASCVD risk, and by 3% and 6%, respectively, of patients at very high ASCVD risk (p <0.001; for both comparisons). CONCLUSIONS: This snap-shot study was the first to show the high estimated prevalence of FH in the Arabian Gulf region (about 3-fold the estimated prevalence worldwide), and is a "call-to-action" for further confirmation in future population studies. The small proportions of patients that achieved target LDL-C values implied that health care policies need to implement nation-wide screening, raise FH awareness, and improve management strategies for FH.

BACKGROUND: Lung ultrasound (LUS) is a bedside imaging tool that has proven useful in identifying and assessing the severity of pulmonary pathology. The aim of this study was to determine LUS patterns, their clinical significance, and how they compare to CT findings in hospitalized patients with coronavirus infection. METHODS: This observational study included 62 patients (33 men, age 59.3±15.9 years), hospitalized with pneumonia due to COVID-19, who underwent chest CT and bedside LUS on the day of admission. The CT images were analyzed by chest radiographers who calculated a CT visual score based on the expansion and distribution of ground-glass opacities and consolidations. The LUS score was calculated according to the presence, distribution, and severity of anomalies. RESULTS: All patients had CT findings suggestive of bilateral COVID-19 pneumonia, with an average visual scoring of 8.1±2.9%. LUS identified 4 different abnormalities, with bilateral distribution (mean LUS score: 26.4±6.7), focal areas of non-confluent B lines, diffuse confluent B lines, small sub-pleural micro consolidations with pleural line irregularities, and large parenchymal consolidations with air bronchograms. LUS score was significantly correlated with CT visual scoring (rho = 0.70; p<0.001). Correlation analysis of the CT and LUS severity scores showed good interclass correlation (ICC) (ICC =0.71; 95% confidence interval (CI): 0.52-0.83; p<0.001). Logistic regression was used to determine the cut-off value of ≥27 (area under the curve: 0.97; 95% CI: 90-99; sensitivity 88.5% and specificity 97%) of the LUS severity score that represented severe and critical pulmonary involvement on chest CT (CT: 3-4). CONCLUSION: When combined with clinical data, LUS can provide a potent diagnostic aid in patients with suspected COVID-19 pneumonia, reflecting CT findings.
RESUMO
The prognostic impact of beta-blockers (BB) in coronary artery disease (CAD) is controversial, especially in the post-reperfusion era. We studied in-hospital cardiovascular events in patients hospitalized for acute HF, a previous history of CAD and a left ventricular ejection fraction (LVEF) ≥40%, in relation to BB on admission; and 1-year outcome in relation to BB on discharge, in the GULF aCute heArt failuRe (GULF-CARE) registry. From a total of 5005 patients included in the GULF-CARE registry, 303 patients with a previous history of CAD and a LVEF ≥40% on BB were propensity-matched to 303 patients without BB on admission. In-hospital mortality (OR= 0.82; 95% CI [0.35-1.94]), stroke and cardiogenic shock were not reduced by BB. On discharge, 306 patients on BB, including the ones newly diagnosed with myocardial infarction as a precipitating cause of HF, were propensity-scored matched with 306 patients without BB. Mortality (OR= 0.86; 95%CI [0.51-1.45], hospitalization for HF or PCI/CABG at 1 year were also not reduced by BB at discharge. In summary, our data show that BB have a neutral effect on in-hospital and 1-year outcomes in acute heart failure patients with a previous history of CAD and a LVEF ≥40%.

AIMS: The aim of this study is to determine the impact of diabetes mellitus on all-cause mortality and rehospitalization rates at 3 months and at 1 year in patients admitted with acute heart failure (AHF) stratified by left ventricular ejection fraction (EF). METHODS AND RESULTS: We analysed consecutive patients admitted to 47 hospitals in seven Middle Eastern countries (Saudi Arabia, Oman, Yemen, Kuwait, United Arab Emirates, Qatar, and Bahrain) with AHF from February to November 2012 with AHF who were enrolled in Gulf CARE, a multinational registry of patients with heart failure (HF). AHF patients were stratified into three groups: HF patients with reduced (EF) (HFrEF) (<40%), HF with mid-range EF (HFmrEF) (40-49%), and HF patients with preserved EF (HFpEF) (≥50%). Analyses were performed using univariate and multivariate statistical techniques. The mean age of the cohort was 59 ± 15 years (ranging from 18 to 99 years), and 63% (n = 2887) of the patients were males. A total of 2258 (49%) AHF patients had diabetes mellitus. The mean EF was 37 ± 14%. A reduced EF was observed in 2683 patients (59%), whereas 962 patients (21%) had mid-range and 932 patients (20%) had preserved EF. Multivariable analyses demonstrated no significant differences in all-cause mortality between diabetics and non-diabetics in all the three types of HF; at 3 months follow-up: HFrEF [adjusted odds ratio (aOR), 1.30; 95% confidence interval (CI): 0.94-1.80; P = 0.119], HFmrEF (aOR, 0.98; 95% CI: 0.51-1.87; P = 0.952), and HFpEF (aOR, 0.69; 95% CI: 0.38-1.26; P = 0.225); and at 12-months follow-up: HFrEF (aOR, 1.25; 95% CI: 0.97-1.62; P = 0.080), HFmrEF (aOR, 1.07; 95% CI: 0.68-1.68; P = 0.783), and HFpEF (aOR, 1.07; 95% CI: 0.67-1.72; P = 0.779). There were also no significant differences in rehospitalization rates between diabetics and non-diabetics in all the three types of HF; at 3 months follow-up: HFrEF (aOR, 0.94; 95% CI: 0.74-1.19; P = 0.581), HFmrEF (aOR, 0.82; 95% CI: 0.53-1.26; P = 0.369), and HFpEF (aOR, 1.06; 95% CI: 0.64-1.78; P = 0.812); and at 12-months follow-up: HFrEF (aOR, 0.93; 95% CI: 0.73-1.17; P = 0.524), HFmrEF (aOR, 0.81; 95% CI: 0.56-1.17; P = 0.257), and HFpEF (aOR, 1.29; 95% CI: 0.82-2.05; P = 0.271). CONCLUSIONS: There were no significant differences in 3 and 12 months all-cause mortality as well as rehospitalization rates between diabetics and non-diabetic patients in all the three types of AHF patients stratified by left ventricular ejection fraction.

AIM: To determine the prevalence, genetic characteristics, current management and outcomes of familial hypercholesterolaemia (FH) in the Gulf region. METHODS: Adult (18-70 years) FH patients were recruited from 9 hospitals and centres across 5 Arabian Gulf countries. The study was divided into 4 phases and included patients from 3 different categories. In phase 1, suspected FH patients (category 1) were collected according to the lipid profile and clinical data obtained through hospital record systems. In phase 2, patients from category 2 (patients with a previous clinical diagnosis of FH) and category 1 were stratified into definitive, probable and possible FH according to the Dutch Lipid Clinic Network criteria. In phase 3, 500 patients with definitive and probable FH from categories 1 and 2 will undergo genetic testing for 4 common FH genes. In phase 4, these 500 patients with another 100 patients from category 3 (patients with previous genetic diagnosis of FH) will be followed for 1 year to evaluate clinical management and cardiovascular outcomes. The Gulf FH cohort was screened from a total of 34,366 patients attending out-patient clinics. RESULTS: The final Gulf FH cohort consisted of 3,317 patients (mean age: 47±12 years, 54% females). The number of patients with definitive FH is 203. In this initial phase of the study, the prevalence of (probable and definite) FH is 1/232. CONCLUSION: The prevalence of FH in the adult population of the Arabian Gulf region is high. The Gulf FH registry, a first-of-a-kind multi-national study in the Middle East region, will help in improving underdiagnosis and undertreatment of FH in the region.
