In the 1998 Lifestyle Heart Trial by Ornish et al., what was the most accurate estimate of the reduction in reported frequency of angina after one year?

In the 1998 Lifestyle Heart Trial conducted by Dean Ornish and colleagues, patients who adhered to a comprehensive lifestyle modification program experienced a significant reduction in the frequency of angina. The trial emphasized the importance of a plant-based diet, regular exercise, stress management, and social support. The results demonstrated that participants reported about a 90% reduction in angina frequency after one year of following these lifestyle changes.

This substantial alleviation of angina symptoms underscores the powerful impact that lifestyle modifications can have on heart health, particularly for individuals with coronary artery disease. The study illustrated not only the potential for lifestyle interventions to enhance cardiac function but also highlighted the role of lifestyle medicine in potentially reversing heart disease. This finding has had lasting implications in the field of lifestyle medicine, emphasizing the value of non-pharmacological approaches in managing cardiovascular conditions.
