Cardiovascular Health Index and Risk of Stroke Público

Stroke is a leading cause of death and disability in the United States, with an estimated 600,000 incident strokes annually. Despite the advent of promising treatments, prevention is still the best approach in reducing the burden of stroke. A healthy lifestyle and achieving low risk factor levels can reduce the risk of stroke by about 80%. The American Heart Association and American Stroke Association proposed a definition of cardiovascular health and developed a new public health metric, the "cardiovascular health index" (CVHI), which incorporates several traditional cardiovascular risk factors and lifestyle behaviors and can be evaluated over time. The concept emphasizes primordial prevention by defining goals for health factors and behaviors and is meant to be simple in order to facilitate dissemination and implementation in the community. The new cardiovascular health metric has not been specifically evaluated in relation to stroke risk. This dissertation aims at bridging the gaps in public health and clinical knowledge on the utility of the new cardiovascular health metric in relation to stroke prevention. It contributes novel insight on the utility of the new metric of cardiovascular health for stroke prediction, and the impact of family history, familial and environmental factors. Knowledge gained from this dissertation will be useful for implementation of public health and individualized approaches that would increase the prevalence of a better cardiovascular health profile for stroke prevention.
