Randomized trial of cardiovascular prevention in Norway combining an in-hospital lifestyle course with primary care follow-up: the Hjerteløftet study.

AIMS: Cardiovascular risk factor control is suboptimal in Europe, including Norway. The present study examined the efficacy of a multimodal primary prevention intervention programme based on the existing Norwegian health care system. METHODS AND RESULTS: In this open-label randomized controlled trial, adult patients with elevated cardiovascular risk were randomly assigned to an intervention programme including a hospital-based lifestyle course and primary care follow-up or to a control group (CG). The participants were recruited between 2011 and 2015. Primary outcome was change in validated cardiovascular risk scores, national and international (NORRISK, NORRISK 2, Framingham, PROCAM) between baseline and follow-up. Secondary outcomes included major cardiovascular risk factors. After 36 months the NORRISK score was significantly improved in patients assigned to the intervention group (IG) compared to patients assigned to the CG; absolute difference in mean delta score in the IG (n = 305) compared to mean delta score in the CG (n = 296): -0.92, 95% CI: -1.48 to -0.36, P = 0.001. The results for NORRISK 2, Framingham and PROCAM showed similar significant effects. The secondary endpoints including total cholesterol and blood pressure were only minimally, and non-significantly, reduced in the IG, but the proportion of smokers (P = 0.0028) and with metabolic syndrome (P < 0.0001) were significantly reduced. A limited number of cardiovascular events were observed, IG (n = 9), CG (n = 16). CONCLUSION: In subjects with elevated cardiovascular risk, a newly developed prevention programme, combining a hospital-based lifestyle course and primary care follow-up, significantly reduced cardiovascular risk scores after 36 months. This benefit appeared achievable primarily through improvements in metabolic syndrome characteristics and smoking habits.The study protocol was registered in ClinicalTrials.gov (NCT01741428).

Randomized prospective trial of saphenous vein harvest site infection after wound closure with and without topical application of autologous platelet-rich plasma.

OBJECTIVE: Wound infection is still a common problem after open long saphenous vein harvesting. Platelets are important for the healing process. The hypothesis was that spraying of the wounds with platelet-rich plasma might reduce the frequency of harvest site infections. METHODS: From January to October 2008, 140 patients undergoing first-time coronary artery bypass grafting were randomized into two groups of 70 patients. Both groups had standard surgical leg wound closure and care except topical application of platelet-rich plasma as adjunctive treatment in the active treatment group. End points were wound infection and cosmetic result at 6 weeks. RESULTS: The follow-up was 100% complete. Nine patients (13%) in the treatment group and eight (11%) in the control group experienced harvest site infection (p=0.80). The overall cosmetic result was also similar between the groups (p=0.34), but the top score was borderline and more frequent in the treatment group (p=0.050). CONCLUSION: Topical application of autologous platelet-rich plasma on vein harvest wounds did not reduce the rate of surgical site infection.
