ABSTRACT
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.
ABSTRACT
Background: Left ventricular (LV) dysfunction is the single most accurate predictor of death and one of the most common and lethal consequences after ST segment elevation myocardial infarction (STEMI) that has been substantially decreased by primary percutaneous coronary intervention (PCI). This research investigated the impact of duration of ischemia on the severity and improvement of wall motion abnormalities after revascularization and 40-day follow-up. Methods: This study was performed on 60 STEMI patients, treated with 1ry PCI and distributed in two groups; group1: 37 patients presented early before 12h and group II: 23 patients presented late after 12h. Echocardiogram (ECHO) was done for ejection fraction (EF) and resting segmental wall motion abnormalities (RSWMA) detection after revascularization within 24 h of hospitalization and follow up after 40 days. Results: MI complication showed insignificant difference between both groups. Wall motion score index (WMSI) values in group I were significantly decreased relative to group II during the follow-up period (p=0.001). Major improvement in LV ejection fraction from hospital admission to follow-up (p=0.001) in group I from the beginning of chest pain compared to group II. Correlation between time to wire crossing and WMSI showed significant positive correlation after 40 days in group I (p=0.016) with significant negative correlation with EF after 40 days in group I (p=0.018). Conclusions: Ischemic patients with ? 12 hours symptoms showed a significant degree of recovery from RWMA on follow up after 40 days.
ABSTRACT
Background: Atrial septal defects lead to left to right shunt, the volume of the shunt is determined by RV/LV compliance, defect size, and LA/RA pressure. RV volume overload and pulmonary over circulation are caused by a simple ASD because the RV is more compliant than the LV. The aim of our study was to assess changes in RV systolic function before and after ASD closure either by surgery or transcatheter closure. Methods: This study was conducted on 70 patients diagnosed with ASD Secundum and had subdivided into two groups A (surgical closure) group, and B (percutaneous device closure) group. All patients had been assessed by transthoracic Echocardiography examination for RV systolic Function 24 h before ASD closure, and 6 months after closure. Results: There was a significant decrease in the right ventricle systolic function indices (TAPSE, FAC, Tissue Doppler S wave velocity, and global longitudinal free wall strain) after ASD closure either by surgery or by transcatheter device closure Conclusions: The right ventricle's size and function are affected by a large shunt caused by an ASD secudium. ASD and its consequent volume overload resulted in higher RV myocardial contraction, leading to an increase in strain values and RV systolic function indices, which were reduced and returned to normal values when the left-to-right shunt was eliminated, and the defect was closed.
