Diabetes: Does screening for inducible ischemia improve outcomes?
Nature Reviews. Cardiology
|June 26, 2009
Summary
Screening for inducible myocardial ischemia did not improve clinical outcomes in asymptomatic type 2 diabetes patients. Future research should explore targeted interventions for high-risk individuals based on atherosclerotic burden.
Area of Science:
- Cardiology
- Diabetology
- Preventive Medicine
Background:
- The DIAD trial assessed the impact of screening for inducible myocardial ischemia in asymptomatic type 2 diabetes patients.
- Most participants had well-controlled diabetes and received optimal medical management.
- Few patients in the study underwent revascularization procedures.
Discussion:
- Routine screening for myocardial ischemia did not enhance clinical outcomes in this cohort.
- The study population's excellent medical management may have influenced the results.
- A low rate of revascularization suggests a conservative approach to invasive procedures.
Key Insights:
- Screening for inducible myocardial ischemia offers no discernible benefit for asymptomatic type 2 diabetes patients.
- Current medical management strategies for type 2 diabetes may mitigate the need for routine ischemia screening.
- Individualized risk assessment is crucial for guiding treatment decisions.
Outlook:
- Future studies should investigate the cost-effectiveness of unconditional treatment versus risk-stratified screening.
- Evaluating therapeutic interventions alongside risk-factor management and selective revascularization is recommended.
- Identifying high-risk patients for targeted interventions remains a key objective.

Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis
Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
Diabetes Mellitus: Type 2 and Gestational
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...
Diabetes: Symptoms, Diagnosis, and Complications
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 based on...
Complications of Diabetes Mellitus
Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...
Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Diabetes Mellitus: Overview and Type I Subtype
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...
