ABSTRACT
AIMS: We assessed whether a novel programme to evaluate/communicate predicted coronary heart disease (CHD) risk could lower patients' predicted Framingham CHD risk vs. usual care. METHODS: The Risk Evaluation and Communication Health Outcomes and Utilization Trial was a prospective, controlled, cluster-randomised trial in nine European countries, among patients at moderate cardiovascular risk. Following baseline assessments, physicians in the intervention group calculated patients' predicted CHD risk and were instructed to advise patients according to a risk evaluation/communication programme. Usual care physicians did not calculate patients' risk and provided usual care only. The primary end-point was Framingham 10-year CHD risk at 6 months with intervention vs. usual care. RESULTS: Of 1103 patients across 100 sites, 524 patients receiving intervention, and 461 receiving usual care, were analysed for efficacy. After 6 months, mean predicted risks were 12.5% with intervention, and 13.7% with usual care [odds ratio = 0.896; p = 0.001, adjusted for risk at baseline (17.2% intervention; 16.9% usual care) and other covariates]. The proportion of patients achieving both blood pressure and low-density lipoprotein cholesterol targets was significantly higher with intervention (25.4%) than usual care (14.1%; p < 0.001), and 29.3% of smokers in the intervention group quit smoking vs. 21.4% of those receiving usual care (p = 0.04). CONCLUSIONS: A physician-implemented CHD risk evaluation/communication programme improved patients' modifiable risk factor profile, and lowered predicted CHD risk compared with usual care. By combining this strategy with more intensive treatment to reduce residual modifiable risk, we believe that substantial improvements in cardiovascular disease prevention could be achieved in clinical practice.

The topography of the nerve of Henle was reviewed. Fifty-two human cadaveric upper extremities were studied. In 30 (58%) the nerve was well defined; in 22 (42%) its origin from the ulnar nerve was unidentifiable. The palmar cutaneous branch of the ulnar nerve separated from the ulnar nerve 5 to 11 cm distal to the medial epicondyle of the humerus to divide into its terminal branches in the distal forearm. Four patterns were detected: ulnar, radioulnar, vessel-related, and radial. These shared a consistent vascular branch, which sent 2 branches to the ulnar artery just proximal to the distal ulnar tunnel. Using a tyrosine hydroxylase antibody-based immunohistochemistry technique the nerve was shown to carry sympathetic fibers. Motor fibers were ruled out with Karnovsky's stain, which was used in combination with the tyrosine hydroxylase method in 10 specimens.
