Brief Summary:
The primary aim of this study is to increase our understanding of care-seeking behavior surrounding heart attacks or acute coronary syndromes [ACS]. This study uses an internet based survey to ask individuals how they obtained medical care in the midst of a heart attack. At present, care-seeking delay among individuals stricken with a heart attack prevents them from obtaining the full therapeutic benefit of hospital based medical care in a timely manner to reduce the long term health consequences of a heart attack. By using a self-tailoring survey instrument the study attempts to take into consideration the complex social processes by which the individual and their family make decisions to seek medical care for symptoms of a heart attack. The study is designed to obtain a national sample of ACS care-seeking behavior in the United States.

Study Type : Observational
Actual Enrollment : 2381 participants
Observational Model: Case-Only
Time Perspective: Retrospective
Official Title: Acute Coronary Syndrome and Care-Seeking Delay: A Web Based Behavioral Study
Study Start Date : July 2011
Actual Primary Completion Date : April 2013
Actual Study Completion Date : April 2013

Primary Outcome Measures :
  1. Decision points and situations and circumstances critical to producing patterns of care-seeking that are efficient and expeditious or are protracted and delayed. [ Time Frame: Study participants will be asked to complete a survey of their heart attack care-seeking experiences. The survey will take from 30 minutes to 1 hour to complete depending on their care-seeking activities. ]
    By applying an integrated self-regulatory care-seeking model [ISCM] to ACS care-seeking, we can delineate decision points and circumstances that are critical to producing patterns of care-seeking that are expeditious or delayed. The ISCM model assumes that coping behaviors emerge over time and are initially guided by demographic and structural factors. As the self-regulatory processes emerge, the influence of these factors diminishes and emergent ACS evaluations, advice from others and health care providers, emerging symptoms and emotions, come to determine the duration of ACS care-seeking.

Sampling Method:   Non-Probability Sample
Study Population
This study is designed to gather detailed information on the care-seeking behavior of ACS patients from a sample of sufficient size to allow testing of study hypotheses and provide points of intervention in the ACS care-seeking process. To obtain these data the study will employ a self-administered, self-tailoring web based survey instrument and a sampling design incorporating sampling quotas calculated from NHANES 1999-2000 and 2001-2002 studies to represent the population of the United States with AMI by age, gender, and race, and 2] over sampling of selected groups to meet calculated sampling quotas.

Inclusion Criteria: Acute myocardial infarction, acute coronary syndrome, unstable angina, men & women, all races & ethnicities

Exclusion Criteria: age < 21 years
