Background: Clinical characteristics and outcomes in patients with type 2 diabetes mellitus (T2DM) and acute heart failure (AHF) patients with idiopathic cardiomyopathy are not well known. Objective: The objective of our study is to determine all-cause mortality in patients with idiopathic cardiomyopathy presenting with AHF. Methods: We analyzed the data from 509 consecutive patients with idiopathic cardiomyopathy presenting with AHF to 47 hospitals in seven Middle Eastern countries (Saudi Arabia, Oman, Yemen, Kuwait, United Arab Emirates, Qatar, and Bahrain) between February and November 2012. All patients were stratified according to T2DM. The analyses were performed using the univariate and multivariate statistical techniques. Results: The mean age of the cohort was 52.0 ± 14.8 years. Of the 509 patients, 123 (24.2%) had T2DM and had a higher incidence of major stroke than the nondiabetic group (11.4% vs. 2.8%; P = 0.001). Diabetic patients were also more likely to be associated with hypertension than those without diabetes mellitus (78.9% vs. 21.8%; P < 0.001). Multivariate logistic regression demonstrated that those with cardiogenic shock (adjusted odds ratio [aOR], 59.3; 95% confidence interval [CI]: 20.1-207; P = 0.001) and noninvasive ventilation (NIV) (aOR: 4.19; 95% CI: 1.33-13.1; P = 0.013) were associated with higher odds of all-cause in-hospital mortality. However, age (aOR: 1.00; 95% CI: 0.96-1.03; P = 0.792), T2DM status (aOR: 0.43; 95% CI: 0.10-1.51; P = 0.207), and atrial fibrillation (aOR: 3.95; 95% CI: 0.82-17.2; P = 0.07) were not associated with higher odds of all-cause inhospital mortality. Conclusions: In AHF patients with idiopathic cardiomyopathy, T2DM was not associated with higher odds of all-cause inhospital mortality. Patients on NIV and cardiogenic shock were demonstrated as the independent predictors of increased inhospital mortality. [ABSTRACT FROM AUTHOR]

Background: Patients undergoing TAVR constitute a high-risk population given their comorbidities and out-of-hospital mortality rates remain high despite significant improvements in the overall procedural outcomes. Objectives: The objective of this study was to determine the early and late mortality rates following transfemoral transcatheter aortic valve replacement (TAVR) and identify the risk factors for poor outcomes. Methods: This study population examined patients extracted from 43 publicly funded hospitals in Hong Kong between 2010 and 2019. The study constitutes retrospective analysis of mortality outcomes for severe aortic stenosis patients undergoing TAVR. The primary end points include out-of-hospital 30-day, 1-year, 1-2-year, and 2-5-year mortality rates. Results: A total of 448 patients underwent TAVR and were included into the study. The rates of mortality following TAVR were 1.7%, 3.3%, 1.3%, and 0.22% at 30 days, 1, 1-2, and 2-5 years, respectively. Age and chronic renal failure (CRF) were concluded to be associated with postprocedural mortality. Further analysis of the baseline echocardiographic parameters revealed a higher prevalence of right atrial enlargement (RAE) and tricuspid and pulmonary regurgitation in the deceased subgroup. Conclusion: We report the 30-day, 1-, 1-2-, and 2-5-year all-cause mortality for TAVR of 1.7%, 3.3%, 1.3%, and 0.22% at 30 days. Factors associated with a higher prevalence of mortality include age, CRF, RAE, and tricuspid and pulmonary regurgitation. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Conclusion: In AHF patients with idiopathic cardiomyopathy, T2DM was not associated with higher odds of all-cause in-hospital mortality. Patients on NIV and cardiogenic shock were demonstrated as independent predictors of increased in-hospital mortality. [ABSTRACT FROM AUTHOR]

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.

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.

Objectives: We sought to estimate the mortality and morbidity in diabetic acute heart failure (AHF) patients stratified by left ventricular ejection fraction. Methods: We analyzed the data of patients with AHF from seven Middle Eastern countries (Bahrain, Oman, Yemen, Kuwait, UAE, Qatar, and Saudi Arabia) from February to November 2012, who were enrolled in a multinational registry of patients with heart failure (HF). Results: A total of 2258 AHF patients had diabetes mellitus. The mean age was 63.0±11.0 years (ranging from 18 to 99 years), and 60.3% (n = 1362) of the patients were males. The mean ejection fraction (EF) was 37.0±13.0%. HF with reduced EF (< 40%) (HFrEF) was observed in 1268 patients (56.2%), whereas 515 patients (22.8%) had mid-range (40-49%) (HFmrEF) and 475 patients (21.0%) had preserved EF (≥ 50%) (HFpEF). The overall cumulative all-cause mortalities at three- and 12-months follow-up were 11.8% (n = 266) and 20.7% (n = 467), respectively. Those with HFpEF were associated with lower three-months cumulative all-cause mortality compared to those with HFrEF (7.6% vs. 5.9%; adjusted odds ratio (aOR) = 0.54, 95% confidence interval (CI): 0.31-0.95; p = 0.031), but not significantly different when compared to those with HFmrEF (aOR = 0.86, 95% CI: 0.53-1.40; p = 0.554). There were largely no significant differences among the groups with regards to the 12-months all-cause cumulative mortality (11% vs. 11% vs. 10%; p = 0.984). There were also no significant differences in re-hospitalization rates between the three HF groups not only at three months (23% vs. 20% vs. 22%; p = 0.520), but at one-year follow-up (28% vs. 30% vs. 32%; p = 0.335). Conclusions: Three-month cumulative all-cause mortality was high in diabetic HFrEF patients when compared to those with HFpEF. However, there were no significant differences in mortality at one-year follow-up between the HF groups. There were also no significant differences in re-hospitalization rates between the HF groups not only at three months but also at one-year follow-up in the Middle East. [ABSTRACT FROM AUTHOR]

Aims: This study aims to evaluate the incidence and impact of cardiorenal anaemia syndrome (CRAS) on all‐cause mortality in acute heart failure (AHF) patients stratified by left ventricular ejection fraction (LVEF) status in the Middle East. Methods and results: Data were analysed from 4934 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. CRAS was defined as AHF with estimated glomerular filtration rate of <60 mL/min and low haemoglobin (<13 g/dL for men or <12 g/dL for women). Analyses were performed using univariate and multivariate statistical techniques. The overall mean age of the cohort was 59 ± 15 years, 62% (n = 3081) were men, and 27% (n = 1319) had CRAS. Co‐morbid conditions were common including hypertension (n = 3014; 61%), coronary artery disease (n = 2971; 60%), and diabetes mellitus (n = 2449; 50%). A total of 79% (n = 3576) of the patients had AHF with reduced ejection fraction (HFrEF) (LVEF < 50%). CRAS patients were associated with major bleeding (1.29% vs. 0.6%; P = 0.017), blood transfusion (10.1% vs. 3.0%; P < 0.001), higher re‐admission rate for AHF at 3 months' follow‐up (27.6% vs. 18.8%; P < 0.001) and at 12 months' follow‐up (34.3% vs. 26.2%; P < 0.001). Multivariate logistic regression demonstrated that patients with CRAS were associated with higher odds of all‐cause mortality during hospital admission [adjusted odds ratio (aOR), 2.10; 95% confidence interval (CI): 1.34–3.31; P = 0.001], at 3 months' follow‐up (aOR, 1.48; 95% CI: 1.07–2.06; P = 0.018), and at 12 months' follow‐up (aOR, 1.45; 95% CI: 1.12–1.87; P = 0.004). Stratified analyses showed that CRAS patients with HFrEF were associated with higher odds of all‐cause mortality during hospital admission (aOR, 2.03; 95% CI: 1.20–3.45; P = 0.009) and at 12 months' follow‐up (aOR, 1.42; 95% CI: 1.06–1.89; P = 0.019) but not at 3 months' follow‐up (aOR, 1.43; 95% CI: 0.98–2.09; P = 0.063). However, in AHF patients with preserved ejection fraction (LVEF ≥ 50%), CRAS was not associated with higher odds of all‐cause mortality not only during hospital admission (aOR, 2.15; 95% CI: 0.84–5.55; P = 0.113) but also at 3 months' follow‐up (aOR, 1.87; 95% CI: 0.93–3.76; P = 0.078) and at 12 months' follow‐up (aOR, 1.59; 95% CI: 0.91–2.76; P = 0.101). Conclusions: The incidence of CRAS was 27%. CRAS was associated with higher odds of all‐cause mortality in AHF patients in the Middle East, especially in those with HFrEF. [ABSTRACT FROM AUTHOR]

We evaluated the impact of clopidogrel use on 3- and 12-months all-cause mortality in patients with acute heart failure (AHF) stratified by coronary artery disease (CAD) in patients admitted to 47 hospitals in 7 Middle Eastern countries with AHF from February to November 2012. Clopidogrel use was associated with significantly lower risk of all-cause mortality at 3 months (adjusted odds ratio [aOR], 0.61; 95% confidence interval [CI]: 0.42-0.87; P = .007) and 12 months (aOR, 0.61; 95% CI: 0.47-0.79; P < .001). When the analysis was stratified by CAD, the clopidogrel group in those with AHF and CAD was also associated with significantly lower risk of all-cause mortality at 3 months (aOR, 0.56; 95% CI: 0.38-0.83; P = .003) and 12 months (aOR, 0.58; 95% CI: 0.44-0.77; P < .001). However, in AHF patients without CAD, clopidogrel use was not associated with any survival advantages, neither at 3 months (aOR, 0.99; 95% CI: 0.32-3.11; P = .987) nor at 12 months (aOR, 0.80; 95% CI: 0.37-1.72; P = .566). Clopidogrel use was associated with short- and long-term all-cause mortality in patients with AHF and CAD. In AHF patients without CAD, clopidogrel use did not offer any survival advantage.

Background: Fasting during the month of Ramadan is practiced by over 1.5 billion Muslims worldwide. It remains unclear, however, how this change in lifestyle affects heart failure, a condition that has reached epidemic dimensions. This study examined the effects of fasting in patients with acute heart failure (AHF) using data from a large multi-center heart failure registry.Methods and Results: Data were derived from Gulf CARE (Gulf aCute heArt failuRe rEgistry), a prospective multi-center study of consecutive patients hospitalized with AHF during February-November 2012. The study included 4,157 patients, of which 306 (7.4%) were hospitalized with AHF in the fasting month of Ramadan, while 3,851 patients (92.6%) were hospitalized in other days. Clinical characteristics, precipitating factors, management, and outcome were compared among the two groups. Patients admitted during Ramadan had significantly lower prevalence of symptoms and signs of volume overload compared to patients hospitalized in other months. Atrial arrhythmias were significantly less frequent and cholesterol levels were significantly lower in Ramadan. Hospitalization in Ramadan was not independently associated with increased immediate or 1-year mortality.Conclusions: The current study represents the largest evaluation of the effects of fasting on AHF. It reports an improved volume status in fasting patients. There were also favorable effects on atrial arrhythmia and total cholesterol and no effects on immediate or long-term outcomes.

We investigated the role of systolic blood pressure (SBP) in relation to in-hospital and postdischarge mortality in patients admitted with acute heart failure (AHF). The SBP of 4848 patients aged ≥18 years admitted with AHF was categorized into 5 groups: ≤90, 91 to 119, 120 to 139, 140 to 161, and >161 mm Hg. After adjusting for several confounders, multivariate logistic regression models showed that admission SBP was a significant predictor of mortality among both patients with preserved left ventricular function (defined as left ventricular ejection fraction [LVEF] ≥40%) and patients with left ventricular dysfunction (LVEF <40%). The adjusted odds ratios of in-hospital, 3-month, and 1-year mortality in the lowest SBP groups were 7.06 (95% confidence interval [CI]: 3.28-15.20; P < .001), 2.59 (95% CI: 1.35-4.96; P = .004), and 3.10 (95% CI: 2.04-4.72; P < .001) times the odds in the highest admission group (SBP > 161 mm Hg), respectively. We conclude that low admission SBP is an independent predictor of mortality in patients with AHF. The higher the admission SBP, the better the prognosis, regardless of age or LVEF.

We assessed the frequency and implications of a history of syncope of up to 1 year prior to hospitalization with acute heart failure (AHF) between February and November 2012. Data were collected for 5005 patients hospitalized with AHF and analyzed and compared according to the absence/presence of a history of syncope (group 1 vs group 2). Prior syncope among patients with heart failure was 5.3%. Age, gender, hypertension, atrial fibrillation, bundle branch block, left ventricular ejection fraction (LVEF), and obstructed coronary vessels were comparable in the 2 groups. Group 2 patients were more likely to smoke or have diabetes mellitus, stroke, and cardiac arrest. Group 2 patients frequently required aggressive treatment and had more worse in-hospital and 1-year outcomes compared to group 1. After adjustment for age, sex, ethnicity, and LVEF, multivariate regression analysis showed that history of syncope predicted in-hospital mortality (odds ratio: 2.61; 95% confidence interval: 1.707-4.002). History of syncope during the year prior to the index admission with AHF is a marker of worse outcomes regardless of patient age and LVEF. Further studies are required to confirm this observation and its clinical implications. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study was to report the prevalence, clinical characteristics, contributing factors, management and outcome of patients with chronic obstructive pulmonary disease (COPD) among patients hospitalized with heart failure (HF). Methods: Data were derived from Gulf Care (Gulf acute heart failure registry), a prospective multicenter study of 5005 consecutive patients hospitalized with acute heart failure during February to November 2012 in seven Middle Eastern countries. Data were described and compared for demographics, management and outcomes. Results: The prevalence of COPD among HF patients was 10%. COPD patients were older, more likely to be female and to have diabetes, hypertension, chronic kidney disease and sleep apnea (P = 0.001 for all) when compared to non-COPD patients. Contributing factors for hospitalization were systemic infection and atrial arrhythmias in COPD patients compared to acute coronary syndrome, uncontrolled hypertension and anemia in the non-COPD patients. Left-ventricular ejection fraction was higher in COPD patients; while BNP levels were comparable between the two groups. Non-invasive ventilation was used more frequently among COPD patients compared to non-COPD patients (P = 0.001). On multivariate logistic regression analysis, COPD was not associated with increased risk in-hospital and one-year death among acute heart failure (AHF) population and β blockers treatment appear to have neutral mortality effect in COPD patients with HF. Conclusion: COPD have distinct cardiovascular risk profile and precipitating factors for hospitalization with HF when compared to non-COPD patients. COPD history had no impact on the short-term and one-year mortality. [ABSTRACT FROM AUTHOR]
