Patients with type 2 DM may develop a cardiomyopathy often called diabetic cardiomyopathy which is characterized by left ventricular diastolic dysfunction in early stages

Type 2 DM is associated with various types of subclinical target organ damage resulting in elevated risk of CVD events, moreover there is growing evidence that a prediabetic status, such as impaired fasting glucose is also related to subclinical target organ damage when compared to a group with normal glucose metabolism Diabetes mellitus is a well-studied major risk factor for coronary heart diseases, which is one of the leading causes of death worldwide. Another distinct entity of diabetes-related cardiac affection is the diabetic cardiomyopathy. This entity of cardic affection by diabetes still needs more and more attention, not only because it is common in diabetic patients, but also because of its easy detection by the simple, inexpensive and widely available diagnostic echocardiography.

The proposed mechanisms that may be implicated in the pathogenesis of diabetic cardiomyopathy include autonomic dysfunction, microvascular disease, interstitial fibrosis and metabolic disorders. However, the actual causes and mechanisms remain unclear.

Inclusion Criteria:

• DM type 2 who are asymptomatic of any cardiac symptom.

Exclusion Criteria:

• Patients of known hypertension with or without treatment.
• Cardiac arrhythmias.
• Cardiomyopathy.
• Valvular heart disease.
• Heart failure.
• Chronic pulmonary disease.
• Extreme age.
• Chronic renal failure.
• Subjects with poor transthoracic echo window.

Will assess the prevelance and frequency of diastolic dysfunction of the left ventricle in patients with asymptomatic type 2 DM and to explore its relation to other parameters, including patients' age, sex, the duration of diabetes and glycemic control.
