Plasma Catestatin in Patients with Acute Coronary Syndrome.
OBJECTIVE
To measure plasma catestatin levels in patients with acute coronary syndrome and investigate whether there is an association between catestatin levels and long-term outcome.


METHODS
Patients (n = 170) with suspected acute coronary syndrome who underwent emergency coronary angiography were enrolled, including 46 with acute ST-segment elevation myocardial infarction (STEMI), 89 with unstable angina pectoris (UAP), and 35 without coronary artery disease (CAD). All patients were followed for 2 years to measure the occurrence of major adverse cardiovascular events (MACEs), including death from a cardiovascular cause, recurrent acute myocardial infarction, or hospital admission for heart failure or revascularization.


RESULTS
On average, the plasma catestatin levels in patients with STEMI (0.80 ± 0.62 ng/ml) and UAP (0.99 ± 0.63 ng/ml) were significantly lower than the levels seen in the control group with no evidence of CAD (1.38 ± 0.98 ng/ml; p = 0.001). In multivariable linear regression, body mass index, presence of hypertension, and type of CAD were independently related to the plasma catestatin level. However, there were no significant differences in MACEs between patients with high and low levels of catestatin.


CONCLUSIONS
The plasma catestatin levels in patients with STEMI and UAP were lower than the levels seen in patients without CAD.
