Background & Objectives: Type 2 diabetes is a major cardiovascular risk factor such as HTN, HLP and smoking. A primary diabetic cardiomyopathy represents a high risk factor for heart failure in the absence of ischemic, valvular and hypertensive heart disease in the diabetic population. CAD is more common in diabetic patients and it is almost asymptomatic.

  Unquestionably, an early detection of LV damage and CAD is a major goal for the prevention of cardiac disease in the diabetic population.

  Methods: This study was done as Cross-Sectional method. The study sample consisted of 40 patients with type 2 diabetes mellitus without hypertension and cardiac symptoms (mean age 47 years) who recourse to diabetes clinic of Ardabil Imam Khomeini Hospital during 2009-2010. Left ventricular (LV) function was studied by echocardiography and exercise test using Bruce protocol. Data from the patients were collected and analyzed using SPSS 17 software.

  Results: All studied cases had a normal systolic function. 22 cases (55%) had diastolic dysfunction and 8 people (20%) had a positive stress test, which all had diastolic dysfunction too.

  Conclusion: This study showed that an impairment of left ventricular diastolic function occurs early in the natural history of diabetes mellitus and CAD is more common in diabetic patients with diastolic dysfunction.

  Background & Objectives: Low dose aspirin has been widely used in the prevention and treatment of cardiovascular disease. The bimodel action of aspirin on serum uric acid showed that aspirin at a high dosage promoted uricusuria while intermediate doses were (1-2gr/day) caused uric acid retention. The main goal of this study was to survey the effect of low dose aspirin on serum level of uric acid in patients with ischemic heart disease.

  Methods: The study design was cross-sectional and analytical type. In this study we selected 60 patients who used low dose aspirin among the patients of Imam Khomeini hospital's heart clinic (2008-9) and their information was registered in special questionnaires including serum level of uric acid and creatinine before and after prescription of aspirin. Data was then statistically analyzed using Paired t test and Willcoxon.

  Results: Of 60 patients 11 ( 18.3 % ) were under 50 years and 49 ( 81.7%) were above 50 years. The male to female ratio was 1.72 (38: 63.3% versus 22: 36.7%). 53.3 % of patients showed an increase in serum uric acid, but 46.7% did not. No significant differences in uric acid levels was found in patients under 50 years before and after administration of aspirin. Serum uric acid levels were increased after administration of 0.1unit of aspirin.

  Conclusion: Low -dose aspirin (80 mg/ day) caused a slight but significant increase in serum uric acid and creatinine levels in patients over 50 years of age.
