Myocardial dysfunction and cardiovascular disease in type 2 diabetes
1a Department of Medical Research , Bærum Hospital, Vestre Viken Hospital Trust , Drammen , Norway.
Summary
Type 2 diabetes (T2DM) significantly increases heart dysfunction and cardiovascular disease (CVD) risk, often undetected early. A multifactorial approach, not just glucose control, is key for managing these risks in T2DM patients.
Area of Science:
- Cardiology
- Endocrinology
- Metabolic Diseases
Background:
- Type 2 diabetes mellitus (T2DM) is linked to myocardial dysfunction and cardiovascular disease (CVD), with dysfunction potentially affecting 75% of patients.
- Diabetic myocardial dysfunction is often asymptomatic and subclinical, complicating diagnosis due to co-morbidities and lack of standardized criteria.
- Pathophysiology involves hyperglycemia and free fatty acids, leading to heart failure (HF) risk and worse outcomes post-cardiac events.
Purpose of the Study:
- To highlight the high prevalence and diagnostic challenges of myocardial dysfunction in T2DM.
- To emphasize the need for advanced diagnostic tools for early detection of subclinical cardiac changes.
- To discuss the role of T2DM in accelerated atherosclerosis, CAD, and stroke, and the limitations in current diagnostic methods for CAD.
Main Methods:
- Review of existing literature on T2DM, myocardial dysfunction, and cardiovascular disease.
- Analysis of pathophysiological mechanisms linking hyperglycemia, free fatty acids, and cardiac dysfunction.
- Evaluation of current diagnostic challenges and the need for novel biomarkers for CAD detection.
Main Results:
- Myocardial dysfunction is highly prevalent in T2DM but often overlooked due to its asymptomatic nature.
- Accelerated atherosclerosis, driven by inflammation, leads to high rates of CAD and stroke in T2DM patients.
- Current diagnostic tests for CAD in T2DM have limited sensitivity, necessitating new biomarkers.
Conclusions:
- A multifactorial approach targeting multiple cardiovascular risk factors is more effective than solely focusing on glucose lowering for macrovascular events.
- Emerging research suggests this comprehensive strategy may also improve heart failure outcomes in T2DM.
- Improved diagnostic strategies, including sensitive echocardiography and novel biomarkers, are crucial for managing cardiovascular complications in T2DM.

738
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,...

5.4K
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...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

783
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

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 is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
