[Show abstract][Hide abstract] ABSTRACT: Inflammatory markers have been associated with clinical outcome in patients with acute coronary syndrome (ACS). The present study evaluated the role of high-sensitivity C-reactive protein (CRP) measurements as a predictor of late cardiovascular outcomes after ACS. One hundred and ninety-nine ACS patients in a Coronary Care Unit from March to November 2002 were included and were reassessed clinically after approximately 3 years. Clinical variables and CRP levels were evaluated as predictors of major cardiovascular events (MACE, defined as the occurrence of cardiac death, ischemic stroke or myocardial infarction) and mortality. Statistical analyses included Cox multivariable analysis and survival curves (Kaplan-Meier). Of the 199 patients, 11 died within 1 month (5.5%). Of the 188 remaining patients, 22 died after a mean follow-up of 2.9 +/- 0.5 years. Baseline CRP levels for patients with MACE (N = 57) were significantly higher than those of patients with no events (median = 0.67 mg/L; 25th-75th percentiles = 0.32 and 1.99 mg/L vs median = 0.45 mg/L; 25th-75th percentiles = 0.24 and 0.83 mg/L; P < 0.001). Patients with CRP levels >3 mg/L had a significantly lower survival than the other two groups (1-3 and <1 mg/L; P = 0.001, log-rank test). The odds ratio for MACE was 7.41 (2.03-27.09) for patients with CRP >3 mg/L compared with those with CRP <1 mg/L. For death by any cause, the hazard ratio was 4.58 (1.93-10.86). High CRP levels predicted worse long-term outcomes (MACE and death by any cause) in patients with ACS.

[Show abstract][Hide abstract] ABSTRACT: To compare conventional and transdisciplinary care in a tertiary outpatient clinic for patients after their first acute myocardial infarction.
One hundred fifty-three patients with acute myocardial infarction were randomized at hospital discharge and followed-up to compare conventional (n=75) and transdisciplinary care (n=78). They were submitted to a clinical evaluation, received a dietary plan, and were re-evaluated twice in 60-180 days by a nurse, dietitian and physician, when new clinical and laboratory data were collected. The primary outcome was clinical improvement, as evaluated by an index including reduction of body weight, lowering of blood pressure, smoking cessation, increase in physical activity and compliance with medication.
The groups were similar at baseline: 63.4% were men, 89.9% had an acute myocardial infarction with ST-segment-elevation, 32.7% were diabetic, and 72.2% were hypertensive. The clinical improvement index was similar between the studied groups: in 33.3 % (transdisciplinary care) vs. 30.4 % (conventional care) of patients, the improvement was very good (P=1.000). Rates of re-hospitalization and death (p=0.127) were similar between transdisciplinary and conventional care. Compliance with diet was higher for transdisciplinary care (50.0%) vs. conventional care (26.1%) (p=0.007), as was compliance with visits (73.3 vs. 40.3%, respectively, p<0.001).
Compliance with diet and visits was higher for transdisciplinary care vs. conventional care; however, the transdisciplinary approach did not provide more clinical benefits than the conventional approach after patients' first acute myocardial infarction in this setting.

To evaluate the role of glycemia and inflammatory markers as predictors of late cardiovascular outcomes after ACS.
One hundred and ninety-nine ACS patients of a Coronary Care Unit were included, from March to November 2002. They were reassessed clinically after approximately 3 years. Clinical variables, glycemia, CRP and fibrinogen were evaluated as event and mortality predictors. Statistical analyses included Cox multivariate analysis and survival curves (Kaplan-Meier).
At admission, 16.7% had normal glycemia. After 3 years, this proportion increased to 55.2%; the 40.6% who belonged to the borderline category decreased to 27.1%; the 42.7% with elevated glycemia decreased to 17.7%. Glycemia was not associated with the development of major cardiovascular events (MACE) and mortality at follow-up ( approximately 3 years). Considering MACE, CRP (p<0.001), but not fibrinogen, was predictive in bivariate analysis. Regarding mortality, both fibrinogen (p=0.020) and CRP (p=0.008) were predictive in bivariate analysis.
Glycemia was not associated with late mortality after ACS, but inflammatory markers were, suggesting that these are more sensitive markers to predict events in long-term. Moreover, glucose intolerance prevalence is lower in the follow-up after the ACS episode.
