Evaluation of left atrial volume and function by real time three-dimensional echocardiography in anemic patients without overt heart disease before and after anemia correction

AbstractThere are few data on the effects of low hemoglobine levels on the left atrium (LA) in anemic patients. Our aim was to evaluate left atrial (LA) volume and functions in anemic patients using real time three-dimensional echocardiography (RT3DE) and also to investigate changes in variables of LA after the correction of anemia. In total, 55 iron-deficiency anemia patients without traditional cardiovascular (CV) risk factors and 30 age- and gender-matched controls were studied. Assessments included history, physical examination and echocardiography. Of the 55 patients with anemia enrolled, 50 (39 females and 11 males 40.3  years) were followed and underwent echocardiography after correction of the anemia. LA maximum volume (LAVmax), LA minimal volume (LAVmin), LAVmax index (LAVI), before atrial contraction volume (LAVpreA), LA total emptying fraction, LA active emptying volume were higher in anemic patients. LA pass ive emptying fraction was significantly lower in anemic patients. Following correction of anemia, LA volume and function parameters were observed to be significantly reduced. Moreover, significant increase was noted in LA passive emptying fraction. Correlation analysis was performed and a significan t negative correlation was noted between the percentage change in hemoglobin level and percentage change in LAVI (r = − 0.382, p = 0.003). It was shown that volume and functions of LA are impaired in anemic patients. Ho...

AbstractCongenital heart disease (CHD) has been one of the most important contributors to neonatal mortality in the western world for the past 2 decades. With improvement in basic neonatal medical care in most parts of our country, the traditional contributors to neonatal mortality such as birth asphyxia and infections have reduced in numbers. This has hence thrust greater focus on CHD. Facilities with capability to diagnose and intervene on neonates with critical CHD are available in most states. Refinements in surgical techniques and advances in post-operative care have ensured that most neonates with critical CHD can un...

In conclusion, T2D impairs vascular function by dysregulated autophagy. Therefore, autophagy could be a potential target for overcoming diabetic microvascular complications.

A perhaps surprisingly large fraction of the losses can be averted by strength training, but there are nonetheless inexorable process...

This study investigated if statins would similarly reduce postoperative arrhythmias in patients undergoing THA. METHODS:: We queried a large Medicare and private-payer database from 2005 to 2012 and identified 12,075 patients who were on a statin prior to THA. We then age and sex matched 34,446 non-statin users who underwent THA. Baseline comorbidities and postoperative complications were obtained and assessed via standard descriptive statistics. RESULTS:: The statin users had more preoperative comorbidities including congestive heart failure, valvular heart disease, pulmonary and renal disease, diabetes, hyperte...

Conclusion: The findings of the study showed that NGAL associated with NT-proBNP was a stronger predictor of the primary endpoint than NGAL or NT-proBNP alone. The level of NGAL was rising in hypertension, ischemia, anemia, hypoalbuminemia, diabetes or arrhythmias.Kidney Blood Press Res 2018;43:1865 –1877

CONCLUSION:The variables that interplay in cases of severe aortic stenosis are what cause these patients to be so difficult to manage, and specific therapies targeted to fix one issue often worsen the effects of another issue. If someone is in respiratory distress, their airway and breathing needs to be secured, either through non-invasive or invasive means. Next, the patient ’s blood pressure needs to be stabilized. Oftentimes the most appropriate agent will be a positive inotrope, with consideration of a vasoactive agent in persistent hypotension. Once a patient is stabilized, determining the extent of damage to th...
