Heart Failure II: Pathophysiology01:29

Heart Failure II: Pathophysiology

761
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Diabetes Mellitus: Type 2 and Gestational

4.4K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Cardiomyopathy II: Dilated Cardiomyopathy

482
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Diabetes: Symptoms, Diagnosis, and Complications

2.1K
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

13.8K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Diabetes Mellitus: Overview and Type I Subtype

4.9K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Area of Science:

  • Cardiology
  • Diabetology
  • Medical Imaging

Background:

  • Cardiovascular events are the leading cause of death in diabetic patients.
  • Early detection of cardiac issues in diabetes is a research priority.
  • Left ventricular diastolic dysfunction (LVDD) is an early indicator of diabetic cardiomyopathy.

Purpose of the Study:

  • To review recent advancements in echocardiographic assessment of LVDD in diabetes.
  • To compare current (2016) LVDD guidelines with previous (2009) recommendations.
  • To evaluate LVDD's role in predicting cardiovascular events and diabetic cardiomyopathy.

Main Methods:

  • Systematic review of echocardiographic studies on LVDD.
  • Analysis of studies adhering to 2016 LVDD guidelines.
  • Comparison of 2016 guidelines with 2009 recommendations.

Main Results:

  • The 2016 LVDD algorithm is more effective in predicting cardiovascular events in established LVDD.
  • The updated algorithm shows reduced specificity in grading indeterminate cases.
  • Elevated E/e' index suggests early diastolic impairment and predicts diabetic cardiomyopathy.
  • The 2016 guidelines may aid in identifying 'indeterminate' LVDD cases for T2DM screening.

Conclusions:

  • The updated echocardiographic guidelines for LVDD improve cardiovascular event prediction in diabetes.
  • Further research, including longitudinal studies, is needed to understand T2DM's subtle cardiac manifestations.
  • Early identification of subclinical cardiac signs in T2DM is clinically important but requires more investigation.
