TWO DIMENSIONAL ECHO IS DIAGNOSTIC.
I have carefully gone through your concern,and would like to address the same.
As per your wife's clinical history,it becomes important to evaluate her cardiac status at the earliest.
Diabetic individuals are more prone to get macro vascular complications of the disease,due to metabolic stress
imposed on the heart largely.The symptoms in her, currently point to congestive symptoms of a slowly progressing heart failure
,quite rightly termed as Congestive Heart Failure.
If diagnosed and treated early ,it has excellent patient outcomes.This is my ultimate current suggestion to you.Following diagnostic interventions can have a positive impact in assessing her overall health status.
2.A full 12 lead E.C.G/E.K.G
3.Blood sugar-fasting and post prandial.
4.HBIac or Glycated hemoglobin
5.Tread mill testing, if needed under an expert cardiologist guidance.
6.Blood lipid profile
The above tests form basic screening protocol to evaluate heart disease
in diabetics.This theme can accurately diagnose the cardiac and other organ related issues and form basis for an early and effective treatment protocols,if rightly followed and interpreted.
I hope and wish this feedback from me is quite helpful and convincing to you,
Please feel free to post your further follow up queries if any,i shall feel humble to answer them as well.
Wish you a good health.
