Preliminary results of the acute Heart Failure registry in the DELTA region of Egypt (DELTA-HF): a database and a quality initiative project.

BACKGROUND: Data about heart failure in Egypt is scarce. We aimed to describe the clinical characteristics and diagnostic and treatment options in patients with acute heart failure in the Delta region of Egypt and to explore the gap in the management in comparison to the international guidelines. RESULTS: DELTA-HF is a prospective observational cohort registry for all consecutive patients with acute heart failure (AHF) who were admitted to three tertiary care cardiac centers distributed in the Delta region of Egypt. All patients were recruited in the period from April 2017 to May 2018, during which, data were collected and short-term follow-up was done. A total of 220 patients (65.5% were males with a median age of 61.5 years and 50.9% had acute decompensation on top of chronic heart failure) was enrolled in our registry. The risk factors for heart failure included rheumatic valvular heart disease (10.9%), smoking (65.3%), hypertension (48.2%), diabetes mellitus (42.7%), and coronary artery disease (28.2%). Left ventricular ejection fraction (LVEF) was less than 40% in 62.6%. Etiologies of heart failure included ischemic heart disease (58.1%), valvular heart disease (16.3%), systemic hypertension (9.1%), and dilated non-ischemic cardiomyopathy (15.5%). Exacerbating factors included infections (28.1%), acute coronary syndromes (25.5%), non-compliance to HF medications (19.6%), and non-compliance to diet (23.2%) in acute decompensated heart failure (ADHF) patients. None of our patients had been offered heart failure device therapy and only 50% were put on beta-blockers upon discharge. In-hospital, 30 days and 90 days all-cause mortality were 18.2%, 20.7%, and 26% respectively. CONCLUSIONS: There is a clear gap in the management of patients with acute heart failure in the Delta region of Egypt with confirmed under-utilization of heart failure device therapy and under-prescription of guideline-directed medical therapies particularly beta-blockers. The short-term mortality is high if compared with Western and other local registries. This could be attributed mainly to the low-resource health care system in this region and the lack of formal heart failure management programs.

Assessment of left and right atrial geometrical changes in patients with stable coronary artery disease: Left and right atrial strain and strain rate imaging study.

OBJECTIVE: In patients with coronary artery disease (CAD), there are several studies that assessed the left ventricular (LV) function by strain (S) and strain rate (SR) imaging. The aim of this study is to evaluate the function of both atria in patients with CAD using strain and strain rate imaging, and to correlate this with the severity of CAD. METHODS: We conducted a prospective, single center case control study for 40 consecutive patients who presented to our department with chronic stable angina and were candidates for invasive coronary angiography. We enrolled patients from December 2013 to May 2014 and each patient was subjected to echocardiographic assessment of E/e' of mitral valve, left atrial volume index (LAVI), right atrial volume index (RAVI), and peak atrial longitudinal strain (es) and strain rate (SR) during LV systole. This was followed by invasive coronary angiography for assessment of the severity of CAD using Gensini score. Patients were classified according to angiographic results into 3 groups: Group I (Gensini score = zero), Group II (Gensini score > 0 and < 20) and Group III (Gensini score ≥ 20). RESULTS: There was no statistically significant difference between the three groups in either LA volumes (Vmin, Vmax) and distensibility with p value of 0.272, 0.126, and 0.243 respectively or RA volumes and distensibility with a p value of 0.671, 0.183, and 0.259 respectively. On the other hand, LA & RA systolic S and SR were significantly lower among CAD patients in comparison with the group of normal coronaries. Mean LA S and SR was decreased in group III than group II (15.97 ±â€¯3.73, 21.8 ±â€¯6.75 % and 1.11 ±â€¯0.30, 1.81 ±â€¯1.23 s-1) with p value of 0.005&0.041 respectively. RA systolic S and SR were significantly lower in the 2 groups with CAD than the group with normal coronaries with a p value of 0.001 and 0.002 respectively. CONCLUSION: In patients with CAD and normal EF, borderline E/e' ratio and normal atrial size, there are decreased LA and RA systolic S and SR parameters with no effect on atrial volumes or distensibility. Accordingly, this could prove that atrial wall deformation occurs early in CAD even before any changes in atrial volumes or dimensions.

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.
