The goal of the campaign "plus leben", a project designed to run for at least 5 years, is to heighten the awareness of patients at risk of heart disease and to provide them with an appropriate prevention program. During the first two years of the campaign 20,000 visitors were registered on the homepage, 400,000 tests for risk of heart disease were distributed, and more than 3,000 health information brochures were requested. Thus, a survey of patients was designed to provide information on the extent to which preventive measures are effective. The survey, which was carried out by mail, had a response rate of 28%, or 230 participants. In the random sample, consisting of about 60% men and 40% women, only 16% are younger than 50 years of age. Thus the survey provides a representative picture of the affected target group. The test for risk of cardiac disease provided by "plus leben" led to an increase in awareness of preventive measures in more than two thirds of the respondents, and 60% also completed the test. Although only a fourth of the patients are regularly informed by their physician about preventive measures, the campaign has led about 90% of the respondents to make fundamental or at least partial changes in their lifestyle. In connection with the study it was shown that the media play an important role in providing information on preventive measures. Communication in the doctor's office as an important building block in raising consciousness about atherosclerosis prevention could be further improved.
