Abstract

Recent data indicated that statin therapy may fail to reduce the incidence of coronary events in patients concomitantly using beta blockers. The aim of the present study was to examine whether the concomitant use of beta blockers would modify the anti-inflammatory action of statins. Changes in C-reactive protein (CRP) between days 1 and 5 after myocardial infarction were evaluated in 189 patients treated with simvastatin alone (S), beta blockers alone (B; propranolol or metoprolol), S + B, or neither of these 2 medications (N) in a prospective observational cohort. At baseline, median CRP was lower in the S group (0.40 mg/dl, interquartile range 0.1 to 0.6) than the other groups (B: 0.6 mg/dl, interquartile range 0.4 to 1.6; S + B: 0.5 mg/dl, interquartile range 0.3 to 1.2; and N: 0.6 mg/dl, interquartile range 0.2 to 1.5). By day 5, median CRP was 1.3 mg/dl (interquartile range 0.7 to 2.6), 4.3 (interquartile range 1.6 to 8.8), 4.6 (interquartile range 2.8 to 9.5), and 4.4 (interquartile range 1.9 to 9.9) for the S, B, S + B, and N groups, respectively. After adjusting for log(e) baseline CRP, the difference in log(e) CRP between days 1 and 5 was significantly lower in the S group compared with the B (-0.74 +/- 0.23 [SE], p = ...Continue Reading

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
