conclusions presence of cae in patients with cas increases its cardiovascular event rate. isolated cae is not a benign finding and mi can occur. risk factors of cae are similar to cas, but c/s is more associated with cae than cas. dm is seen in cae patients less than cas. results hypertension (htn), dyslipidemia (dlp), and male sex were matched in both groups without significant difference. cig...
