Key stages in the development of Acute Coronary Syndrome 1.Ischemic cascade 2.Plaque formation and rupture 3.Coronary occlusion and MI 4.Ventricular remodeling

REMODELING PREVENTION  Pharmacological intervention: -ACE-inhibitors -Beta-blockers -Diuretics -Ca-blockers and other  PTCA

AIM We aimed at assessing the correlation between the amplitude of the left ventricular remodeling and persistence of elevated circulating levels of an inflammation marker - highly sensitive CRP - at 7 +/- 2 days after an AMI in patients with type 2 DM.

MATERIALS AND METHODS 45 patients Inclusion criteria:  Acute myocardial infarction  DM type II  Optimal medical treatment  Primary PCI Exclusion criteria:  History of cardiac surgery  Previous myocardial infarction  Age under 18 The LV function and remodeling were assessed at baseline and at 6 months after the infarction.

MATERIALS AND METHODS Patients underwent through several steps:  Clinical examination  Laboratory examination  ECG  Echocardiography  Coronarography

The study population was divided into 2 groups: Group 1: Group 1: 22patients with low-to-intermediate risk (hsCRP<3mg/l) Group 2: Group 2: 23 patients with high-risk (hsCRP>3mg/l)

Conclusions The persistence of a marked inflammation at seven days post-infarction is associated with a more severe impairment of ventricular function in patients with type 2 DM and acute myocardial infarction. The diabetic patients with persistently high levels of hs-CRP at seven days post-infarction have a poorer outcome, as reflected by lower ejection fractions, marked enlargement of the ventricular cavities and the development of ventricular remodeling at six months following the infarction.
