Our objective was to assess whether bypassing the emergency room (ER) is associated with meaningful reduction in Major Adverse Cardiac and Cerebrovascular Event (MACCE) or mortality in a large cohort of ST Elevation Myocardial Infarction (STEMI) patients. Prior studies suggest that bypassing the emergency room reduces door-to-balloon time (DBT). However, it is not clear whether this translates into reduced mortality. We analyzed data of 1,552 consecutive patients with STEMI treated by primary percutaneous coronary intervention (PCI) and enrolled in the Acute Coronary Syndrome Israeli Survey (ACSIS) registry. Thirty percent of patients (n = 459) arrived directly to the Intensive Cardiac Care Unit or catheterization laboratory and 70% (n = 1093) were assessed first in the ER. Our primary end points were DBT, 30-day MACCE, and 30-day and 1-year mortality. Our secondary end points were pre-discharge ejection fraction less than 40%, in-hospital pulmonary edema, in-hospital cardiogenic shock, ST resolution, and duration of hospitalization. Bypassing the ER was associated with signficantly shorter DBT (59 vs. 97 minutes, P = 0.001). There was no difference in 30-day MACCE and 30-day or 1-year mortality between the 2 study groups. The findings were consistent in multiple subgroups, including women, anterior STEMI, off hours PCI, and patients with pain-to-door (PDT) time of less than 120 minutes. Bypassing the ER is associated with significant shortening of DBT. This reduction, however, is not associated with any change in 30-day MACCE and 30-day or 1-year mortality.

Background: C-reactive protein (CRP) elevated in inflammation is associated with atherosclerotic disease. We describe the distribution of CRP and its association with coronary heart disease (CHD) risk factors in a large CHD patient group. Methods: This analysis comprises 2,723 male and 256 female CHD patients, included in the Bezafibrate Infarction Prevention (BIP) study. High sensitive CRP levels were determined in frozen plasma samples. Results: CRP distribution, was normalized upon log transformation. Levels among women were higher than in men in the entire group (4.4 vs. 3.5 mg/l) and in each age group. Co-morbidities, smoking, lower education level, and use of cardiovascular drugs, were associated with elevated CRP levels in both sexes. The correlation between CRP and body mass index (BMI), insulin and glucose was stronger among women. The explained variability in CRP level was larger in women (20%) compared to men (13%). Among women, BMI explained 10% of CRP variability, whereas the contribution of each variable among men was significantly smaller. Conclusions: Among men and women with CHD, CRP level was correlated with traditional risk factors and to a lesser degree to manifestation of CHD. BMI is the main contributor to CRP variability, explained by these factors among women.
