Inflammatory, lipid, and metabolic profile in acute ischemic syndrome: correlation with hospital and posthospital events

OBJECTIVE: To associate the markers lipid profile, inflammatory profile (high-sensitivity C-reactive protein HSCRP and fibrinogen), and metabolic profile (glucose determination) with hospital and posthospital events in patients with acute ischemic syndrome (AIS) and to describe the predictors of mortality in this population. METHODS: A cohort study with 199 patients with AIS (unstable angina, acute myocardial infarction (AMI) with or without ST segment elevation) admitted to the intensive care unit (ICU) of a university cardiology Hospital, from March to November 2002. The previous diseases, the medication in use, and the coronary risk factors were recorded. The clinical events considered in the hospital were reinfarction, angina, heart failure (HF), ventricular fibrillation, and death; the posthospital events considered (30 days after hospital discharge) were reinfarction, angina, HF, death, and admittance for percutaneous procedures (PTCA) or for revascularization (MRS). RESULTS: HSCRP and altered glycemia were significantly associated with hospital events (P = 0.03 and P < 0.01, respectively); however, they were not associated with posthospital events (P = 0.19 and P = 0.61, respectively). Lipid profile and fibrinogen did not have a statistically significant association in any of the times assessed. Using multiple logistic regression, age (P = 0.04), previous AMI (P = 0.04), myocardial infarction with ST segment elevation (P = 0.008) or without ST segment elevation (P = 0.048), and altered glycemia (P = 0.002) were predictors of hospital mortality. CONCLUSION: Increased HSCRP and altered glycemia were associated with a greater number of hospital events, whereas age, previous AMI, AMI with or without ST segment elevation, and altered glycemia were predictors of hospital mortality.
