[Prevention of coronary disease].

Primary prevention of ischemic heart disease concerns the entire community. The Swiss National Research Program on the Prevention of Cardiovascular Disease has promoted and evaluated prevention activities at town level in the Swiss towns of Nyon and Aarau. Local physicians have played an essential role in establishing a prevention centre involving health professionals, the majority of whom are nonphysicians. Experience at Nyon and Aarau well shows how medical practice and preventive centre complement each other, particularly in improving diet, monitoring blood pressure and reducing tobacco consumption.
