Incremental value of high-sensitivity C-reactive protein and N-terminal pro-B-type natriuretic peptide for the prediction of postoperative cardiac events in noncardiac vascular surgery patients.
High-sensitivity C-reactive protein (hs-CRP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) are associated with the presence of coronary artery disease. The aim of this study was to assess the prognostic value of hs-CRP and NT-proBNP for postoperative cardiac events in noncardiac vascular surgery patients. ⋯ Both hs-CRP and NT-proBNP have additional value in the prediction of postoperative cardiac events in vascular surgery patients. Their integrated use improves cardiac risk stratification.

Randomized Controlled Trial Comparative StudyHemostatic changes and clinical sequelae after on-pump compared with off-pump coronary artery bypass surgery: a prospective randomized study.
To delineate the effects of extracorporeal bypass on biomarkers of hemostasis, fibrinolysis, and inflammation and clinical sequelae. ⋯ On-pump surgery was associated with biochemical evidence of a prothrombotic state early after surgery but no greater incidence of thrombotic events was observed. The prothrombotic state might be a consequence of extracorporeal bypass, compensation in response to more bleeding, or both in patients undergoing on-pump surgery.

B-type natriuretic peptide: a strong predictor of early and late mortality in patients with acute chest pain without ST-segment elevation in the emergency department.
The prognostic importance of early measurement of B-type natriuretic peptide (BNP) in patients with acute chest pain while the diagnosis is still uncertain is unknown. We determined the prognostic value of BNP in these patients immediately after presenting to the emergency department. ⋯ Admission BNP is an independent and powerful marker of early and late cardiac mortality in patients with acute chest pain without ST-segment elevation. These results suggest that BNP should be measured upon arrival at the emergency department for risk stratification in all these patients.

Comparative StudyBody mass index, metabolic syndrome and carotid atherosclerosis.
Body fatness and fat distribution are widely accepted as coronary heart disease risk factors. In this study, we have evaluated the contribution of generalized adiposity, assessed by body mass index (BMI), to carotid atherosclerosis, in participants with or without metabolic syndrome (MetS). ⋯ The present findings suggest that increasing body weight favours the clustering of coronary heart disease risk factors. Overweight and obesity, however, do not independently associate with carotid atherosclerosis.

Comparative Study Controlled Clinical TrialComparison of patients undergoing enhanced external counterpulsation and spinal cord stimulation for refractory angina pectoris.
As more patients survive coronary events, the prevalence of patients with refractory angina pectoris is increasing. The aim was to evaluate the effects of enhanced external counterpulsation (EECP) and spinal cord stimulation (SCS) and compare with optimal medically treated patients with refractory angina. ⋯ The results from this study show that both EECP and SCS therapy reduce angina in patients with refractory angina pectoris; the response to EECP was slightly more effective than that to SCS. Thus, EECP can be used as an alternative treatment for patients not responding to electrical stimulation. The beneficial effects in the treated groups were maintained during the 12 months follow-up period.
