To evaluate a series of thrombotic, inflammatory, and genetic markers for myocardial infarction among participants in the Women's Health Initiative Observational Study (WHI-OS).
To investigate use of Fast Gated Helical Computed Tomography (FGHCT) measures of coronary artery calcium (CAC), FGHCT-CAC, for discrimination of coronary artery disease (CAD) and to quantify progression of coronary artery calcium over time.
To statistically examine cardiovascular disease (CVD) risk in different populations based on data from studies representing national samples, cohort studies, and clinical trials.
To determine the association between flavonoids intake and the prevention of incident cardiovascular disease (CVD).
To determine whether an impairment of myocardial perfusion reserve is an early indicator of coronary artery disease.
To evaluate whether T Wave Alternans can predict ventricular arrhythmias and sudden cardiac death (SCD) in a prospective epidemiologic natural history study. The prospective epidemiologic pilot study included 550 patients that had left ventricular dysfunction and no history of sustained ventricular arrhythmias. The primary hypothesis tested was whether there was an increased risk of having an arrhythmic event when T Wave Alternans was present in the patient. The secondary aims included comparing risk due to T Wave Alternans between the ischemic patients and non-ischemic patients and assessing whether T Wave Alternans remained an independent predictor of risk upon adjustment for other known risk factors for arrhythmic events such as ejection fraction, ventricular ectopy, NSVT, average NN interval, and RR interval variability. The study approach was a standard epidemiologic surveillance technique. The subject population consisted of individuals with Class I to III heart failure who will underwent a TWA and Holter monitor test and then were followed for up to two years or until arrhythmic events occured.
To examine trends in trans-fatty acid intake by using newly available nutrient data to recalculate 24 dietary recalls from the Minnesota Heart Survey.
To continue surveillance of coronary heart disease (CHD) mortality and morbidity in the seven county metropolitan Minneapolis/St. Paul (Twin Cities) areas.
To test the effectiveness of a multicomponent school-based and community-linked intervention in preventing the decline in physical activity levels and cardiovascular fitness in girls in grades 6-8.
