Delta of Egypt Atrial Fibrillation Registry Phase Two

Background: Atrial Fibrillation (AF) is the most frequent cardiac arrhythmia found in clinical practice. The assessed frequency of AF in adults is between 2% and 4%, with greater incidence and frequency rates in developed nations [1,2]. AF prevalence increases with advancing age, and with some cardiac and non-cardiac disorders, also it may exist in the absence of any conditions [2]. We aimed to determine case characteristics, practice patterns, management strategies and outcomes of atrial fibrillation in the delta area of Egypt. Methods: This registry-based cross-sectional study included 1000 atrial fibrillation patients (with any AF patterns) who were allowed to enter ER in cardiac centers and hospitals in middle Delta of Egypt from April 2020 to March 2021. Results: 267 patients (26.7%) were unstable. Heart failure, hypertension, and coronary disease were still prevalent comorbidities in our AF dataset, where hypertension accounts for over 50% of all AF cases. Rheumatic valvular heart disorder was a major underlying disease for the development of AF, still about 25.5% by echocardiography. Lone AF still high 20.6%. CHA2DS2VASc score ?2 is 83.5%. A high proportion of cases were treated with pharmaceuticals for rate control nearly 52.7% of the cases and nearly 30.3% of the cases were given pharmacological medications for the cardioversion to the sinus rhythm and a small proportion of the cases were given electrical cardioversion nearly 7%. Conclusions: Coronary disease, hypertension, and heart failure were still usual comorbidities in AF. Rheumatic valvular heart disease is still about 25.5% of the total registry. Amiodarone is the most prevalent antiarrhythmic medications (AAD) used. lone AF still high 20.6%. minimal use of novel oral anticoagulant (OAC).

Relationship between Aortic Root Diameter and Type 2 Diabetes in Hypertensive Patients

Background: Diabetes mellitus (DM) involves a series of metabolic conditions associated with hyperglycaemia which is caused by defects in insulin secretion and./or insulin action. The aim of this work was assessment of the relationship between Aortic Root (AOR) diameter and type 2 diabetes mellitus (T2DM) in Hypertension (HTN) cases. Methods: This prospective case control study was carried out on 80 HTN cases. Cases were divided in to three groups: Group A (30 HTN cases) with type 2 DM with good metabolic control (Hb AIC ? 7.0), group B: (30 HTN cases) with type 2 DM with poor metabolic control (Hb AIC > 7.0) and C (Control group) 20 HTN, non-DM subjects of the same age and sex group with no other comorbid conditions. Results: FS had a significant decline in group A (P2 = 0.001) and in group B (P3 <0.001) than C. EF had a significant difference among all groups (P <0.001). Early wave declaration time (DT) had a significant decline in group A (P2 = 0.049) and in group B (P3= 0.023) than C. Tissue doppler early velocity wave had a significant difference among all groups (P = 0.004). Tissue doppler early velocity wave had a significant decline in group A and B than C. (P2 = 0.038. P3 = 0.003). Conclusions: AOR in HTN cases had a significant decline in DM cases compared with non-DM cases. In our results, glycaemic control didn’t play a significant role in aortic root.

Role of Resting Electrocardiography and Transthoracic Echocardiography in the Diagnosis of Cardiac Impairments in Type 2 Diabetics

Background: The cardiac changes associated with diabetes are thought to comprise thickening of the myocardium and is characterized by predominantly diastolic dysfunction (DD), the diabetic cardiomyopathy. So, this study aimed to evaluate cardiac impairments in patients in delta region with type 2 diabetes mellitus using resting electrocardiogram (ECG) and resting transthoracic echocardiography. Methods: This was a cross-sectional study carried out on 50 diabetic patients to evaluate of cardiac impairments in patients in delta region with type 2 diabetes mellitus using resting ECG and resting transthoracic echocardiography at the Department of Cardiology, Tanta University Hospitals in a period of six months starting from January 2020 till June 2020. Results: There were significant negative correlations between abnormal echocardiography with (body mass index) BMI, duration of diabetes and systolic blood pressure (SBP) (P<0.05). The sensitivity of ejection fraction (EF), early trans-mitral flow velocity (E), atrial trans-mitral flow velocity (A) and E/A in detecting cardiac changes in type 2 diabetes mellitus (DM) was 68%, 52%, 76%, 72% and specificity was 52%, 68%, 36%, 30% at cut-off value 65, 75, 65, 77.5 and AUC 0.619, 0.606, 0.538, 0.534, respectively (P> 0.05). Conclusions: The effect of DM on the left ventricular (LV) diastolic function is still controversial. Therefore, they need to be further substantiated, preferably with evidence from extensive longitudinal studies in people with type 2 diabetes representative of type 2 diabetes healthcare populations. Echocardiographic and ECG abnormalities are very common in outpatients with type 2 diabetes. DD is the main cardiac impairment caused by DM.

Left Ventricular Geometry and Function in Patients with Gray Zone Hypertension

Background: Hypertension is considered as the silent killer of human because the hypertensive patient may be not aware that he has hypertension and death can occur at any time without the reason being known. We aim to study the effect of gray zone hypertension [SBP from 120-139] and or [DBP from 80-89] which was classified as prehypertension under JNC-7 on the structure, geometry, and operation of the left ventricle using echocardiography Methods: This study included 100 patients who asymptomatic apparent healthy subjects visited cardiology outpatient department (OPD) for routine checkup. Patients were grouped into two equal groups: Group A whose blood pressure was in the gray zone hypertension [SBP from 120-139] and or [DBP from 80-89], and group B with SBP <120 mmHg & DBP <80 mmHg. Results: The two groups being studied were statistically significant different as regard LV geometrical pattern (p=0.028). They were also statistically significant in LV geometrical pattern between the males and females (p<0.05). The two groups were statistically significant different regarding GLS (p =0.001). Conclusions: Gray zone hypertension affects ventricular diastolic function and LV geometry, although systolic function was normal; GLS showed that subclinical LV dysfunction can occur.

Clinical and Echocardiographic Predictor of Atrial Fibrillation in Patient with Rheumatic Mitral Valve Disease

Background: Rheumatic fever principally influences kids in developing states, particularly where deficiency is common. Atrial fibrosis is a mutual characteristic of clinical atrial fibrillation (AF) and is accompanying with AF in a diversity of experiment sittings, Aim and Objectives: The current work aimed to assess whether there are any clinical or echo-cardiographic parameters that expect the existence of AF among cases with rheumatic mitral valve disorder (RMVD), Subjects and Methods: The current study was a comparative cross-sectional was conducted on 100 RMVD cases at cardio-vascular medicine department Tanta university hospitals within 6-mths starting from September 2019. Cases have been allocated into 2 groups: Group-I: 50 cases with sinus rhythm. Group-II: 50 cases with AF, Results: A significant change was found among study groups regarding Fibrosis characteristics, There is a highly significant difference between the three different types regarding mitral valve area (MVA), LA-diameter, LA volume, LA-diameter/BSA and LA volume index, Age, area of mitral valve, LA-diameter and LA volume were found to be significant predictors for AF, Conclusion: Echo-cardiography factors could recognize cases at higher danger of advancing AF among RMVD cases who may benefit from preventive measures.

Effect of Mild Hypothermia on Morbidity and Mortality in Post AMI Cardiogenic Shock

Background: Acute myocardial infarction (AMI) complicated with cardiogenic shock is still associated with a significant death rate. Other interventions, including intra-aortic balloon counter pulsation and medical therapy, failed to improve prognosis in large-scale randomised studies, with the exception of early revascularization. Recently, mild therapeutic hypothermia, in which patients are lowered to 33°C over the course of 24 hours, has been proposed as a therapy option for cardiogenic shock patients. The purpose of this study is to determine the impact of mild hypothermia on morbidity and mortality associated with post-AMI cardiogenic shock. Methods: This randomized, controlled, unblinded trial was conducted on 50 patients with AMI complicated by CS. Patients were randomly allocated into two equal groups; group I received MTH to 33°C for 24-36 h and group II (control group) did not receive MTH. Patients were subjected to full history taking, general and clinical examination, laboratory examination, echo, chest ultrasound (US), coronary angiography data and mild therapeutic hypothermia protocol. Results: Stroke until day 30, duration of mechanical ventilation, length of ICU stay, duration of inotropic support, mortality and pulmonary congestion by US were insignificantly different between both groups. Arterial lactate and mean arterial blood pressure (MAP) at 4h, 6h, 8h, 10h, 12h, 14h, 16h, 18h, 20h were significantly increased in group I than Group II (P value<0.05). and were insignificantly different between both groups at 0h, 2h, 22h, 24h, 26h, 28h, 30h. Serum creatinine at 24h, 48h was significantly increased in group I than Group II (p value <0.05) and was insignificantly different between both groups at 0h. Conclusions: Therapeutic hypothermia (TH) didn’t improve short term outcomes in patients with post AMI cardiogenic shock.
