One of the main goals of in-hospital treatment and outpatient care after heart attack is to relieve angina (or episodic chest pain), according to background information in the article. The prevalence and treatment of chest pain one year after heart attack are largely unknown. “By identifying these factors, a more complete understanding of those patients who are at the greatest risk for angina [chest pain] after myocardial infarction [heart attack] can occur,” the authors write. Identifying this population is important for treating remaining chest pain and improving patient outcomes, including ability to exercise and health-related quality of life.

Thomas M. Maddox, M.D., S.M., of Denver Veterans Affairs Medical Center and University of Colorado Denver, and colleagues studied the occurrence of angina in 1,957 patients recruited from January 2003 to June 2004. Patients filled out questionnaires assessing their chest pain one year after hospitalization for heart attack. Sociodemographic, clinical and other lifestyle factors were also reported.

Of all patients, 389 (19.9 percent) reported angina one year after hospitalization for heart attack. Twenty-four patients (1.2 percent) reported having daily chest pain, 59 (3 percent) reported weekly chest pain and 306 (15.6 percent) reported having chest pain less than once a week.
