- OBJECTIVES: To describe the short-and long-term outcome among patients with an ST-elevation myocardial infarction (STEMI), assessed and treated by the emergency medical services (EMS) in relation to whether they were fast tracked to a coronary care unit (CCU) or admitted via the emergency department (ED). METHODS: Consecutive patients admitted to the CCU at Sahlgrenska University Hospital with ST elevations on admission ECG were analysed with respect to whether they by the EMS were fast tracked to the CCU or the adjacent coronary angiography laboratory (direct CCU group; n=261) or admitted via the ED (ED group; n=235). RESULTS: Whereas the two groups were similar with regard to age and previous history, those who were fast tracked to CCU were more frequently than the ED patients diagnosed and treated as STEMI already prior to hospital admission. Reperfusion therapy was more commonly applied in the CCU group compared with the ED group (90% vs 67%; <0.0001). The delay times (median) were shorter in the direct CCU group than in the ED group, with a difference of 10 min from the onset of symptoms to arrival in hospital and 25 min from hospital arrival to the start of reperfusion treatment (primary PCI or in-hospital fibrinolysis). Patients in the direct CCU group had lower 30-day mortality (7.3% vs. 15.3%; p=0.004), as well as late mortality (>30 days to five years) (11.6% vs. 20.6%; p=0.008). CONCLUSION: Among patients transported with ambulance due to STEMI there was a significant association between early recognition and treatment followed by fast tracking to the CCU and long term survival. A higher rate of and a more rapid revascularisation were probably of significant importance for the outcome.

- The chemokines CCL19 and CCL21 are up-regulated in atherosclerotic disease and heart failure, and increased circulating levels are found in unstable versus stable coronary artery disease.The purpose of this study was to evaluate the prognostic value of CCL19 and CCL21 in acute coronary syndrome (ACS).CCL19 and CCL21 levels were analyzed in serum obtained from ACS patients (n = 1,146) on the first morning after hospital admission. Adjustments were made for GRACE (Global Registry of Acute Coronary Events) score, left ventricular ejection fraction, pro-B-type natriuretic peptide, troponin I, and C-reactive protein levels.The major findings were: 1) those having fourth quartile levels of CCL21 on admission of ACS had a significantly higher long-term (median 98 months) risk of major adverse cardiovascular events (MACE) and myocardial infarction in fully adjusted multivariable models; 2) high CCL21 levels at admission were also independently associated with MACE and cardiovascular mortality during short-time (3 months) follow-up; and 3) high CCL19 levels at admission were associated with the development of heart failure.CCL21 levels are independently associated with outcome after ACS and should be further investigated as a promising biomarker in these patients.

- Abstract BACKGROUND: Antibodies against proinflammatory phosphorylcholine (anti-PC) seem to be protective and reduce morbidity. We sought to determine whether low levels of immunoglobulin-M (IgM) autoantibodies against PC add prognostic information in acute coronary syndromes (ACS). METHODS: IgM anti-PC titers were measured in serum obtained within 24h of admission from 1185 ACS patients (median age 66years, 30% women). We evaluated major acute cardiovascular events (MACE) and all-cause mortality short- (6months), intermediate- (18months) and long- (72months) terms. RESULTS: Low anti-PC titers were associated with MACE and all-cause mortality at all follow-up times. After adjusting for clinical variables, plasma troponin-I, proBNP and CRP levels, associations remained at all times with MACE, short and intermediate terms also with all-cause mortality. With anti-PC titers below median, adjusted hazard ratios at 18months were for MACE 1.79 (95% confidence interval [CI]: 1.31 to 2.44; p=0.0002) and for all-cause mortality 2.28 (95% CI: 1.32 to 3.92; p=0.003). Anti-PC and plasma CRP were unrelated and added to risk prediction. CONCLUSIONS: Serum IgM anti-PC titers provide prognostic information above traditional risk factors in ACS. The ease of measurement and potential therapeutic perspective indicate that it may be a valuable novel biomarker in ACS.

- BACKGROUND: Most patients with acute coronary syndrome quit smoking when hospitalized, although several have been found to relapse and resume smoking within 3 months. AIM: This paper reports a study to identify factors that can predict who will resume smoking after hospitalization for an acute coronary syndrome. METHODS: Patients (n = 1320) below the age of 75 years, admitted to a Swedish university hospital coronary care unit with acute coronary syndromes, between September 1995 and September 1999, were consecutively included. Data were collected from hospital medical records and included information on previous clinical history, former illnesses and smoking. During their hospitalization, an experienced nurse interviewed the patients by using a structured questionnaire to obtain additional information. Patients were followed up 3 months after the discharge. Those who continued to smoke (non-quitters) were compared with those who had stopped (quitters) with regard to age, sex, medical history, clinical course, and intention to quit. To identify factors independently related to continued smoking, a logistical regression in a formal forward stepwise mode was used. RESULTS: Of the patients admitted, 33% were current smokers. Three months after discharge, 51% of these patients were still smoking. There were no significant differences in age, gender or marital status between non-quitters and quitters. In a multivariate analysis, independent predictors of continued smoking were: non-participation in the heart rehabilitation programme (P = 0.0008); use of sedatives/antidepressants at time of admission (P = 0.001); history of cerebral vascular disease (P = 0.002), history of previous cardiac event (P = 0.01); history of smoking-related pulmonary disease (P = 0.03) and cigarette consumption at index (P = 0.03). CONCLUSIONS: Smoking patients who do not participate in a heart rehabilitation programme may need extra help with smoking cessation. The findings may provide means of identifying patients in need of special intervention.

- Objective. We investigated whether levels of C-reactive protein (CRP), interleukin-6 (IL-6), secretory phospholipase A(2) group IIA (sPLA(2)-IIA) and intercellular adhesion molecule-1 (ICAM-I) predict late outcomes in patients with acute coronary syndromes (ACS). Design. Prospective longitudinal study. CRP (mg L(-1)), IL-6 (pg mL(-1)), sPLA(2)-IIA (ng mL(-1)) and ICAM-1 (ng mL(-1)) were measured at days 1 (n = 757) and 4 (n = 533) after hospital admission for ACS. Their relations to mortality and rehospitalization for myocardial infarction (MI) and congestive heart failure (CHF) were determined. Setting. Coronary Care Unit at Sahlgrenska University Hospital, Gothenburg, Sweden. Subjects. Patients with ACS alive at day 30; median follow-up 75 months. Results. Survival was related to day 1 levels of all markers. After adjustment for confounders, CRP, IL-6 and ICAM-1, but not sPLA(2)-IIA, independently predicted mortality and rehospitalization for CHF. For CRP, the hazard ratio (HR) was 1.3 for mortality (95% confidence interval (CI): 1.1-1.5, P = 0.003) and 1.4 for CHF (95% CI: 1.1-1.9, P = 0.006). For IL-6, HR was 1.3 for mortality (95% CI: 1.1-1.6, P < 0.001) and 1.4 for CHF (95% CI: 1.1-1.8, P = 0.02). For ICAM-1, HR was 1.2 for mortality (95% CI: 1.0-1.4, P = 0.04) and 1.3 for CHF (95% CI: 1.0-1.7, P = 0.03). No marker predicted MI. Marker levels on day 4 provided no additional predictive value. Conclusions. In patients with ACS, CRP, IL-6, sPLA(2)-IIA and ICAM-1 are associated with long-term mortality and CHF, but not reinfarction. CRP, IL-6 and ICAM-1 provide prognostic information beyond that obtained by clinical variables.

- OBJECTIVES: The objectives of this study were to examine the time course of the inflammatory response in acute coronary syndromes (ACS) and to assess the markers of inflammation and their relation to disease severity. METHODS: We prospectively studied 134 patients with ACS who survived for at least 30 months. The patients were divided into four groups: acute myocardial infarction (MI) with (n=54) or without (n=46) ST-segment elevation and unstable angina with (n=14) or without (n=20) increased risk. Plasma levels of C-reactive protein (CRP), interleukin-6 (IL-6), secretory phospholipase A(2) group IIA (sPLA(2)-IIA), and intercellular adhesion molecule-1 (ICAM-1) were measured on days 1 and 4 and after 3 and 30 months. RESULTS: The highest levels of CRP and sPLA(2)-IIA were seen on day 4 but for IL-6 on day 1. These three markers, but not ICAM-1, were significantly related to disease severity, CKMB, and ejection fraction. Patients in Killip class II-IV had higher levels than those in Killip class I. The individual acute-phase responses correlated with marker levels at 3 and 30 months. ICAM-1 correlated with the development of congestive heart failure. CONCLUSIONS: In ACS there seems to be an individual predisposition to inflammatory response. Plasma IL-6 is the first marker to rise, while sPLA(2)-IIA and CRP peak later. All three markers, especially CRP, may discriminate between MI and non-MI. ICAM-1 seems to reflect other aspects of the inflammatory processes than the other markers. The results emphasize the complexity of the inflammatory response in ACS and stress the need for further studies involving multiple markers.

- OBJECTIVE: The aim of this study was to assess the short- and long-term prognostic significance of interleukin-18 (IL-18) levels in patients with acute coronary syndromes (ACS). METHODS AND RESULTS: In patients hospitalized with ACS (median age, 66 years; 30% females), we evaluated associations of serum IL-18 levels from day 1 (n=1261) with the short- (<3 months) and long-term (median, 7.6 years) risk of death, development of congestive heart failure (CHF), and myocardial infarction (MI). IL-18 was not significantly associated with short-term mortality. In the long term, IL-18 levels were significantly related to all-cause mortality, even after adjustment for clinical confounders (hazard ratio [HR], 1.19; 95% confidence interval, 1.07 to 1.33; P=0.002). Long-term, cardiovascular mortality was univariately related to IL-18, and the adjusted relation between noncardiovascular mortality and IL-18 was highly significant (HR, 1.36; 95% confidence interval, 1.11 to 1.67; P=0.003). IL-18 independently predicted CHF, MI, and cardiovascular death/CHF/MI in both the short and long term. Measurements from day 1 of ACS and 3 months after ACS had a similar power to predict late outcome. CONCLUSIONS: The addition of the measurement of IL-18 to clinical variables improved the prediction of risk of all-cause and noncardiovascular mortality. The association between IL-18 and noncardiovascular mortality is intriguing and warrants further study.
