Serum alpha-1-antitrypsin level in Iraqi patients with coronary heart disease

This study was designed to estimate the level of serum alpha -1- antitrypsin in patients with coronary heart disease. Patients were clinically subdivided into stable angina 25 patients, unstable angina 30 patients and myocardial infarction 50 patients. A control sample of 30 individuals was matched with patient for age and sex. Non-significant elevation of serum alpha one antitrypsin were noted in MI cases compared to healthy control individuals, even some MI patients showed decreasing level of alpha one antitrypsin, which may return to hereditary alpha one antitrypsin deficiency in Iraqi patients. The Stable angina patients group showed non-significant decrease in alpha one antitrypsin level compared to healthy control, while unstable angina patients group showed significant decrease in alpha one antitrypsin level that will may facilitate developing disease towards MI. All present results need additional studies to be carried out on larger samples of Iraqi individuals and alpha one antitrypsin deficient patients, furthermore, highlighting on the relationship between alpha one antitrypsin and risk of coronary heart disease.
