Educational Strategies to Prevent Prehospital Delay in Patients at High Risk for Acute Myocardial Infarction: A Report by the National Heart Attack Alert Program

Abstract

An estimated 13 million people in the United States have coronary heart disease (CHD), peripheral vascular disease, or cerebrovascular disease. The risk for subsequent myocardial infarction (MI) and death in these patients is fivefold to sevenfold higher than for the general population. Many effective therapies are now available for patients with unstable angina, acute myocardial infarction (AMI), potentially fatal arrhythmias, and cardiogenic shock if they seek and receive care expeditiously. However, delays in accessing and receiving care are a continuing problem, threatening the effectiveness of available treatments. Patients with previously diagnosed CHD, including a previous MI, have the same or greater delay times as those without prior MI or CHD. Because of the high-risk status of these patients, combined with the problem of delay in seeking care, this Working Group of the National Heart Attack Alert Program Coordinating Committee advises physicians and other healthcare providers of their important role in reducing treatment delay in these patients. The Working Group recommends that primary care clinicians in the office and in inpatient settings provide these patients and their family members or significant others with contingency counseling about actions to take in response to symptoms of an AMI. The counseling should address the emotional aspects (e.g., fear and denial) that patients and those around them may experience, as well as barriers that may be associated with the healthcare delivery system. Assistance from other healthcare providers (e.g., nurses) should be solicited to initiate, reinforce, and supplement the counseling. A Patient Advisory Form is offered as an aid to providers in counseling their high-risk patients about these issues. Other materials and aids should be considered as well. Physicians' offices and clinics should devise a system to triage patients rapidly when they call or walk in seeking advice for possible AMI symptoms. Further research is needed to learn more about effective counseling strategies; symptom manifestation in high-risk groups, including the elderly, women, and minorities; and healthcare delivery systems that enhance access to timely care for patients with prior CHD or other clinical atherosclerotic disease.
