Objective To analyze the relationship between knowledge on cardiovascular disease prevention and ideal cardiovascular health behaviors and factors in community elderly. Methods From December, 2015 to May, 2016, totally 400 elderly in communities with-out overt cardiovascular disease were conveniently sampled. The level of knowledge on cardiovascular disease prevention was measured by self-designed cardiovascular disease prevention questionnaire. And each of the ideal cardiovascular health components was collected. Re-sults A total of 390 responses were valid. 13.85%community elderly were with high level of the knowledge. There were significant differ-ences in the distribution of cardiovascular health indexes among various leves of the knowledge groups (χ2>9.974, P<0.05), except choles-terol (P>0.05). The level of the knowledge was positively correlated with the scores of cardiovascular health behaviors and health factors (r>0.354, P<0.01). The cardiovascular health score, health behaviors score, health factors score and number of ideal cardiovascular health in-dexes were significantly different among various levels of the knowledge groups (F>8.961, P<0.001). Conclusion The level of knowledge on cardiovascular disease prevention was positively correlated with cardiovascular health behavior and health factors. The scores of cardio-vascular health score, health behaviors score and health factors increased with the improvement of knowledge on cardiovascular disease pre-vention.
