Background: Elevated Gamma-glutamyltransferase (GGT) level is independently correlated with conditions associatedwith increased atherosclerosis, such as obesity, elevated serum cholesterol, high blood pressure and myocardial infarction. It is also demonstrated that serum gamma-glutamyltransferase activity is an independent risk factor for myocardial infarction and cardiac death in patients with coronary artery disease. Although the relationship between gamma-glutamyltransferase and coronary artery disease has been reported, not many studies have shown the relationship between changes ofgamma-glutamyltransferase in acute coronary syndromes and a well established coronary risk factor high sensitive C-reactive protein. (hs-CRP). Aims: In this study, how gamma-glutamyltransferase levels changed in acute coronary syndromes and its relationship with high sensitive C-reactive protein if any were studied. Patients & Methods: This trial was carried out at Kosuyolu Cardiovascular Training and Research Hospital and Van Yuksek Ihtisas Hospital, Turkey. 219 patients (177 males and 42 females) presenting with acute coronary syndrome, and 51 control subjects between September 2007 and September 2008 were included in the study. Serum gamma-glutamyltransferase, high sensitive C-reactive protein, serum lipoprotein levels and troponin I were determined. Results: Serum gamma-glutamyltransferase and high sensitive C-reactive protein levels were higher in acute coronary syndrome patients compared to control. There was also correlation between gamma-glutamyltransferase and high sensitive C-reactive protein levels. Conclusion: Serum gamma-glutamyltransferase and high sensitive C-reactive protein levels were higher in acute coronary syndrome patients. In subgroup analyses, the higher difference with Non-ST elevation myocardial infarction and ST elevation myocardial infarction groups than unstable angina oectoris group proposes a relationship between gamma-glutamyltransferase and severity of acute coronary syndromes.
Ggt Levels in Type Ii Diabetic Patients With Acute Coronary Syndrome (Does Diabetes Have Any Effect on Ggt Levels in Acute Coronary Syndrome?)
(Springer-verlag Italia Srl, 2013) Emiroglu, Mehmet Yunus; Esen, Ozlem Batukan; Bulut, Mustafa; Karapinar, Hekim; Kaya, Zekeriya; Akcakoyun, Mustafa; Esen, Ali Metin
Elevated gamma-glutamyltransferase (GGT) level is independently correlated with conditions associated with increased atherosclerosis, such as obesity, elevated serum cholesterol, high blood pressure and myocardial infarction. It is demonstrated that serum GGT activity is an independent risk factor for myocardial infarction and cardiac death in patients with coronary artery disease. Diabetes is also a well-known cardiovascular risk factor and an equivalent of coronary artery disease. Although the relationship between GGT and coronary artery disease has been reported, there are limited data exploring the changes of GGT in acute coronary syndromes, especially in patients with diabetes. So, this study aimed to determine changes in GGT level in diabetic and non-diabetic acute coronary syndromes. This trial was carried out at Kosuyolu Cardiovascular Training and Research Hospital and Van Yuksek Ihtisas Hospital, Turkey. A total of 219 patients (177 men and 42 women) presenting with acute coronary syndrome) and 51 control subjects between September 2007 and September 2008 were included in the study. Serum gamma-glutamyltransferase and serum lipoprotein levels were determined. The resuls indicated that serum GGT levels were higher in acute coronary syndrome patients compared with control. In subgroup analyses, there was no difference between diabetic and non-diabetic subgroups. There was also weak correlation between GGT and blood glucose levels. There was no correlation between GGT and serum lipoprotein levels. In conclusion, serum GGT levels were higher in acute coronary syndrome patients. In subgroup analyses, There was no difference between diabetic and non diabetic subgroup.
