Acute and long-term effects on myocardial ischemia of intermittent and continuous transdermal nitrate therapy in stable angina.

The aim of this study was to compare the efficacy and safety of continuous and intermittent transdermal nitrate therapy using ambulatory electrocardiographic (Holter) monitoring. Eighty-five patients with stable angina pectoris and positive exercise test results participated during their concomitant antiischemic medication in a randomized open trial lasting 12 weeks. After a 3-week run-in period with continuous therapy (10 mg/24 hours), patients were randomized to either continuous- or intermittent-therapy groups.

Results of a one-year worksite and mass media based intervention on health behaviour and chronic disease risk factors.

The North Karelia Worksite Intervention Study was carried out to assess the effectiveness of worksite-based innovative intervention on chronic disease risk factors. The one-year intervention combined use of mass media, worksite opinion leaders, risk assessment and counselling and other health education measures. The study used eight medium sized intervention worksites (IW) and eight matched reference worksites (RW).
