Methods: Consecutive femoral selleck products (n = 224) and carotid (n = 693) endarterectomy

specimens underwent histologic examination for the presence of collagen, calcifications, smooth muscle cells, macrophages, fat, and intraplaque thrombus. Patients were monitored for 3 years after the initial operation and investigated for the occurrence of cardiovascular events. Primary outcome was the composite end point “”major cardiovascular event.”" Alcohol consumption was categorized as no alcohol use, 1 to 10 U/wk, or > 10 U/wk.

Results: The Kaplan-Meier estimate of the major cardiovascular event rate after 3 years of follow-up in the femoral group was 35% for no alcohol use and 21% for 1 to 10 U/wk, whereas only 10% of the group > 10 U/wk sustained a major cardiovascular event (P = .010). The plaques of alcohol consumers in the femoral group click here contained significantly

smaller lipid cores and less macrophage infiltration than in abstainers. In the carotid group, the major cardiovascular event rate was similar in all three groups, and in addition, no difference in plaque composition was observed.

Conclusions: This study shows an inverse relationship between alcohol use and major cardiovascular events after endarterectomy for lower extremity arterial occlusive disease, accompanied by a more stable plaque phenotype. However, no such relationship could be observed for patients with cerebrovascular disease. (J Vasc Surg 2011;54:123-32.)”
“Objective: To assess

depression, anxiety, and anger as well as the variance that these emotions share (conceptualized as negative affect) in relationship to high-frequency heart rate variability (HF-HRV), a specific indicator of parasympathetic cardiac autonomic function related to premature cardiovascular morbidity and mortality. Although individual trait negative emotions have been studied in relation to risk for coronary heart disease (CHD) as well as biological mechanisms leading to CHD end points (e.g., autonomic nervous system [ANS] dysfunction), the degree to which a general tendency to experience negative emotions may account for these relations is not known. Methods: The sample included 653 most community volunteers (51.0% female; 15.8% Black) aged 30 to 54 years (mean +/- standard deviation = 43.8 +/- 7.1 years). Latent constructs of depression, anxiety, and anger were each measured by three scales from well-validated self-report questionnaires. Resting HF-HRV was derived from 5-minute segments of continuous electrocadiographs recorded during both unpaced and paced respiration conditions. Results: Structural equation models (SEM) of the individual trait emotions showed depression and anxiety related inversely to HF-HRV and anger unrelated to HF-HRV. SEM also showed negative affect related inversely to HF-HRV.
