Filter by:To investigate the relationship between the use of prescription drugs and the occurrence of ventricular arrhythmia and sudden death.
To evaluate whether genetic variation in selected candidate genes is associated with risk of sudden cardiac death in the general population.
To compare home use of an automatic external defibrillator (AED) to the use of local emergency medical system in treating survivors of sudden cardiac arrest.
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 continue surveillance of coronary heart disease (CHD) mortality and morbidity in the seven county metropolitan Minneapolis/St. Paul (Twin Cities) areas.
To examine the role of reduced vagal control of heart rate in the increased risk of cardiac mortality associated with anxiety in a population with established coronary artery disease (CAD). A second objective is to determine whether the effects of anxiety are independent of the effects of depression.
To provide a comprehensive analysis of risk factors for the development of clinical cardiotoxicities in over 6,000 children with cancer who had been treated on standardized protocols involving the use of anthracyclines alone or in combination with other potentially cardiotoxic therapies or with no use of anthracycline therapy.
To conduct a cross-sectional epidemiologic study of the determinants of prolonged heart rate corrected QT interval (QTc) among 300 men and 300 woman in the population with the highest known risk of SUDS: Southeast Asian refugees in Thailand. .
To determine if selected circulating blood factors that reflect enhanced thrombogenesis are associated with an increased incidence of recurrent coronary events, including cardiac death or non-fatal myocardial infarction.
To investigate hemostatic variables in relation to cardiovascular risk in the Framingham Offspring Study cohort.
