Heart Failure in the Middle East Arab Countries: Current and Future Perspectives.

For many years, data about heart failure (HF) was only limited to Western countries but in the last few years, well designed heart failure registries have been conducted in many developing countries. The purpose of this review is to summarize the current status regarding the epidemiology and management of heart failure in Middle East Arab countries (MEACs) by analysis of the results of the latest HF registries performed in these countries and to anticipate future perspectives, quality initiatives and areas of research and development. Data has shown that the average age of affected individuals is at least 10 years younger than their Western counterparts. Heart failure with preserved ejection fraction was generally under-represented in these registries to less than 30% of the whole population of heart failure. Coronary artery disease (CAD) constitutes about 55% of causes of heart failure in this region in comparison to about 70% in Western countries. An area that needs development is the investment in establishing specialized heart failure programs to cut the circle of non-compliance and repeated HF admissions to the hospitals. Advances in heart transplantation and mechanical circulatory support will continue to slow down and we are not expecting major changes in the near future but on the other hand, implantation of electronic devices like ICD and CRT is expected to increase significantly in the coming years in these countries.

Endovascular repair of a leaking aortic-arch pseudoaneurysm using graft stent combined with chimney protection to left common carotid artery: Case report and review of literature.

Aortic pseudoaneurysm (PsA) is a rare but serious condition that has high mortality and morbidity rates if untreated. We report a rare case of leaking aortic-arch PsA repaired by thoracic endovascular aortic repair using graft stent with the chimney technique to protect the left common carotid artery. Unlike other cases in the literature, our case was unique, having leaking PsA not related to previous cardiac surgery or aortic dissection. The successful management of this patient using thoracic endovascular aortic repair combined with the chimney technique suggests that this approach may be an attractive therapeutic alternative to treat aortic-arch PsA.

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.

Atrial Fibrillation in Patients Hospitalized With Heart Failure: Patient Characteristics and Outcomes From the HEARTS Registry.

Effect of atrial fibrillation (AF) on short- and long-term outcomes in heart failure (HF) is controversial. Accordingly, we examined this relationship in a national multicenter project using data from the Hearts Function Assessment Registry Trial in Saudi Arabia that studied the clinical features and outcomes of patients admitted with de novo and acute on chronic HF. Out of 2593 patients with HF, 449 (17.8%) had AF at presentation. Patients with AF were more likely to be males and older (mean age 65.2 ± 15.0 vs 60.5 ± 14.8 years) to have a history of ventricular tachycardia/ventricular fibrillation (3.1% vs 1.9%) or cerebrovascular accident (15.0% vs 8.5%). However, they were less likely to have diabetes (66.0% vs 55.9%) or coronary artery disease (55.6% vs 42.3%). The 1-, 2-, and 3-year crude mortality rates were significantly higher in patients with AF (23.2% vs 18.3%, 27.4% vs 22.3%, and 27.8% vs 23.2%, respectively). However, there was no significant difference in mortality after adjusting for covariates. Thus, in patients admitted with HF, AF upon presentation was not associated with increased mortality.

Worsening heart failure in 'real-world' clinical practice: predictors and prognostic impact.

AIMS: The aim of this study was to compare the clinical features, predictors, and clinical outcomes of patients hospitalized with acute heart failure (AHF), with and without worsening heart failure (WHF). METHODS AND RESULTS: We used data from a multicentre prospective registry of AHF patients created in Saudi Arabia. WHF was defined as recurrence of heart failure symptoms or signs-with or without cardiogenic shock. In-hospital short- and long-term outcomes, as well as predictors of WHF are described. Of the 2609 AHF patients enrolled, 33.8% developed WHF. WHF patients were more likely to have a history of heart failure and ischaemic heart disease. Use of intravenous vasodilators, inotropic agents, furosemide infusions, and discharge beta-blockers was significantly higher in WHF patients, while use of discharge ACE inhibitors was higher in patients without WHF. Length of hospital stay was significantly longer for WHF patients than for those without WHF [median (interquartile range) 13 (14) vs. 7 (7) days, P < 0.001]. In-hospital, 30-day, 1-year, and 2-year mortality rates were higher in WHF patients than in non-WHF patients. The adjusted odds ratios for in-hospital, 30-day, and 1-year mortality were 4.13 [95% confidence interval (CI) 2.74-6.20, P < 0.001], 3.17 (95% CI 2.21-4.56, P < 0.001), and 1.34 (95% CI 1.04-1.71, P = 0.021), respectively. The strongest predictors for WHF were having ischaemic cardiomyopathy, AHF with concomitant acute coronary syndrome, and low haemoglobin. CONCLUSION: In real-world clinical practice, WHF during hospitalization for AHF is a strong predictor for short- and intermediate-term mortality, and a cause for longer hospital stays.

Acute heart failure with and without acute coronary syndrome: clinical correlates and prognostic impact (From the HEARTS registry).

BACKGROUND: Little is know about the outcomes of acute heart failure (AHF) with acute coronary syndrome (ACS-AHF), compared to those without ACS (NACS-AHF). METHODS: We conducted a prospective registry of AHF patients involving 18 hospitals in Saudi Arabia between October 2009 and December 2010. In this sub-study, we compared the clinical correlates, management and hospital course, as well as short, and long-term outcomes between AHF patients with and without ACS. RESULTS: Of the 2609 AHF patients enrolled, 27.8 % presented with ACS. Compared to NACS-AHF patients, ACS-AHF patients were more likely to be old males (Mean age = 62.7 vs. 60.8 years, p = 0.003, and 73.8 % vs. 62.7 %, p < 0.001, respectively), and to present with De-novo heart failure (56.6 % vs. 28.1 %, p < 0.001). Additionally they were more likely to have history of ischemic heart disease, diabetes, dyslipidemia, and less likely to have chronic kidney disease (p < 0.001 for all comparisons). The prevalence of severe LV systolic dysfunction (EF < 30 %) was higher in ACS-AHF patients. During hospital stay, ACS-AHF patients were more likely to develop shock (p < 0.001), recurrent heart failure (p = 0.02) and needed more mechanical ventilation (p < 0.001). ß blockers and Angiotensin Converting Enzyme inhibitors were used more often in ACS-AHF patients (p = 0.001 and, p = 0.004 respectively). ACS- AHF patients underwent more coronary angiography and had higher prevalence of multi-vessel coronary artery disease (p < 0.001 for all comparisons). The unadjusted hospital and one-month mortality were higher in ACS-AHF patients (OR = 1.6 (1.2-2.2), p = 0.003 and 1.4 (1.0-1.9), p = 0.026 respectively). A significant interaction existed between the level of left ventricular ejection fraction and ACS-AHF status. After adjustment, ACS-AHF status was only significantly associated with hospital mortality (OR = 1.6 (1.1-2.4), p = 0.019). The three-years survival following hospital discharge was not different between the two groups. CONCLUSION: AHF patients presenting with ACS had worse hospital prognosis, and an equivalent long-term survival compared to AHF patients without ACS. These findings underscore the importance of timely recognition and management of AHF patients with concomitant ACS given their distinct presentation and underlying pathophysiology compared to other AHF patients.

Sex Differences in Patients With Acute Decompensated Heart Failure: Insights From the Heart Function Assessment Registry Trial in Saudi Arabia.

We assessed sex-specific differences in clinical features and outcomes of patients with acute heart failure (AHF). The Heart function Assessment Registry Trial in Saudi Arabia (HEARTS), a prospective registry, enrolled 2609 patients with AHF (34.2% women) between 2009 and 2010. Women were older and more likely to have risk factors for atherosclerosis, history of heart failure (HF), and rheumatic heart and valve disease. Ischemic heart disease was the prime cause for HF in men and women but more so in men (P < .001). Women had higher rates of hypertensive heart disease and primary valve disease (P < .001, for both comparisons). Men were more likely to have severe left ventricular systolic dysfunction. On discharge, a higher use of angiotensin-converting enzyme inhibitors, ß-blockers, and aldosterone inhibitors was observed in men (P < .001 for all comparisons). Apart from higher atrial fibrillation in women and higher ventricular arrhythmias in men, no differences were observed in hospital outcomes. The overall survival did not differ between men and women (hazard ratio: 1.0, 95% confidence interval: 0.8-1.2, P = .981). Men and women with AHF differ significantly in baseline clinical characteristics and management but not in adverse outcomes.

Long-Term Mortality Rates in Acute De Novo Versus Acute-on-Chronic Heart Failure: From the Heart Function Assessment Registry Trial in Saudi Arabia.

AIM: The heart function assessment registry trial in Saudi Arabia (HEARTS) is a national multicenter project that compared de novo versus acute-on-chronic heart failure (ACHF). METHODS AND RESULTS: This is a prospective registry in 18 hospitals in Saudi Arabia between October 2009 and December 2010. The study enrolled 2610 patients: 940 (36%) de novo and 1670 (64%) ACHF. Patients with ACHF were significantly older (62.2 vs 60 years), less likely to be males (64% vs 69%) or smokers (31.6% vs 36.7%), and more likely to have history of diabetes mellitus (65.7% vs 61.3%), hypertension (74% vs 65%), and severe left ventricular dysfunction (52% vs 40%). The ACHF group had a higher adjusted 3-year mortality rate (hazard ratio, 1.6; 95% confidence interval [CI] 1.3-2.0; P < .001). CONCLUSION: Patients with ACHF had significantly higher long-term mortality rates than those with de novo acute heart failure (HF). Multidisciplinary HF disease management programs are highly needed for such high-risk populations.

Clinical features, management, and short- and long-term outcomes of patients with acute decompensated heart failure: phase I results of the HEARTS database.

AIMS: The HEart function Assessment Registry Trial in Saudi Arabia (HEARTS) is a national multicentre project, studying clinical features, management, short- and long-term outcomes, and mortality predictors in patients admitted with acute decompensated heart failure (ADHF). METHODS AND RESULTS: Our prospective registry enrolled 2610 ADHF patients admitted to 18 hospitals in Saudi Arabia between October 2009 and December 2010, and followed mortality rates until January 2013. The patients included 66% men and 85.5% Saudis, with a median age (interquartile range) of 61.4 (15) years; 64% had acute on chronic heart failure (HF), 64.1% diabetes mellitus, 70.6% hypertension, and 55.7% CAD. Exacerbating factors for hospital admission included acute coronary syndromes (37.8%), infections (20.6%), non-compliance with low-salt diet (25.2%), and non-compliance with HF medications (20%). An LVEF<40% was found in 73%. In-hospital use of evidence-based medications was high. All-cause cumulative mortality rates at 30 days, 6 months, 1 year, 2 years, and 3 years were 8.3, 13.7, 19.5, 23.5, and 24.3%, respectively. Important independent predictors of mortality were history of stroke, acute on chronic HF, systolic blood pressure<90 mmHg upon presentation, estimated glomerular filtration rate<60 mL/min, and haemoglobin<10 g/dL. CONCLUSION: Patients with ADHF in Saudi Arabia presented at a younger age and had higher rates of CAD risk factors compared with those in developed countries. Most patients had reduced LV systolic function, mostly due to ischaemic aetiology, and had poor long-term prognosis. These findings indicate a need for nationwide primary prevention and HF disease management programmes.

NT-pro-brain natriuretic peptide levels after valve replacement.

Elevated plasma N-terminal pro-brain natriuretic peptide levels have been demonstrated in patients with chronic valvular disease. To assess whether changes in N-terminal pro-brain natriuretic peptide levels after mitral, aortic, and double-valve replacement reflect changes in heart failure symptoms, a prospective observational nonrandomized study was undertaken in 24 consecutive patients (mean age, 55.3 ± 16.2 years; 58% male) undergoing mitral and/or aortic valve replacement. Mitral valve replacement was carried out in 12 patients, aortic valve replacement in 8, and combined mitral and aortic valve replacement in 4. N-terminal pro-brain natriuretic peptide measurements, echocardiography, and functional class assessment were performed before and 6 months after surgery. A decrease in N-terminal pro-brain natriuretic peptide at 6 months postoperatively was significantly associated with decreased left atrial dimension, left ventricular end-diastolic and end-systolic dimensions, increased ejection fraction, and improvement in functional class. Thus we can hypothesize that measurement of N-terminal pro-brain natriuretic peptide might allow early detection of any clinical deterioration as well as assessment of the long-term outcome in valve replacement patients.

Design and preliminary results of the heart function assessment registry trial in Saudi Arabia (HEARTS) in patients with acute and chronic heart failure.

AIMS: The heart function assessment registry trial in Saudi Arabia (HEARTS) is the first multicentre national quality improvement initiative in the Arab population to study the clinical features, management, and outcomes of inpatients admitted with acute heart failure (AHF) and outpatients with high-risk chronic heart failure (HCHF). METHODS AND RESULTS: We conducted a prospective pilot phase for the registry that included consecutive patients with AHF and HCHF in five tertiary care hospitals in Saudi Arabia between October 2009 and December 2010. The study enrolled 1090 patients, 722 (66.2%) of whom were admitted with AHF and 368 (33.8%) had HCHF. The mean age ± SD of AHF patients was 60.6 ± 15.3 years; 65.2% were men, 55.3% were de novo heart failure, 60.7% had diabetes mellitus, 72.5% had moderate or severe left ventricular (LV) systolic dysfunction, and 51.5% had coronary artery disease as the main aetiology. More than 80% of AHF and HCHF patients were treated with beta-blockers and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers. Patients with HCHF had a similar clinical profile, but only one-third had implantable cardioverter defibrillators. In-hospital mortality was 5.3% for AHF patients and 7.5% at 30 days after hospital discharge. CONCLUSION: Heart failure patients in Saudi Arabia present at a relatively younger age, have a much higher rate of diabetes mellitus, and predominantly have LV systolic dysfunction, which is mainly ischaemic in origin, compared with patients in developed countries. The preliminary results of the study show potential targets for improvement in care.

Predictors of developing significant mitral regurgitation following percutaneous mitral commissurotomy with inoue balloon technique.

Background. Despite the high technical expertise in percutaneous mitral commissurotomy (PMC), mitral regurgitation (MR) remains a major procedure-related complication. The aim of this work is to find out the most sensitive and applicable predictors of development of significant mitral regurgitation (SMR) following percutaneous mitral commissurotomy using Inoue balloon technique. Methods. We studied prospectively the preprocedural (clinical, echocardiography, and hemodynamic) and procedural predictors of significant mitral regurgitation (identified as increase of ≥2/4 grades of pre-PMC MR by color Doppler flow mapping) following valvuloplasty using Inoue balloon in 108 consecutive patients with severe mitral stenosis. Multiple stepwise logistic regression analysis was performed for variables found positive on univariate analysis to determine the most important predictor(s) of developing SMR. Results. The incidence of SMR following PMC using Inoue technique was 18.5% (10 patients). MV scoring systems were the only variables that showed significant differences between both groups (Group A without SMR and Group B with SMR). However, no clinical, other echocardiographic measurements, hemodynamic or procedural variables could predict the development of SMR. Using multiple regression analysis, the best predictive factor for the risk of SMR after Inoue BMV was the total MR-echo score with a cutoff point of 7 and a predictive percentage of 97.7%. Conclusions. The total MR-echo score is the only independent predictor of SMR following PMC using Inoue technique with a cutoff point of 7.
