Abstract
BACKGROUND: Definitive treatment for heart attack is early reperfusion with either angioplasty or thrombolytic therapy, and the benefit is strictly time-dependent. Patient outcomes are improved with either therapy when initiated as soon as possible. Recognition of heart attack symptoms is logically tied to taking action to receive prompt emergency care. Inadequate knowledge of heart attack symptoms may prolong delay. The purpose of this study was to document knowledge about heart attack symptoms in Beijing residents and to identify the characteristics associated with increased knowledge of heart attack. METHODS: A structured survey was conducted in 18 communities in Beijing from March 1 through June 10 in 2006. Addresses and participants were selected randomly following a stratification. The survey was designed to collect knowledge of heart attack symptoms from sampled adults in each community. RESULTS: A total of 4627 respondents completed the questionnaires correctly, and 50.29% of them were female. Totally 64.15% of the respondents reported chest pain or discomfort (common symptoms) as a symptom of heart attack; 75.38% reported at least one of the following eight symptoms as a symptom of heart attack: back pain, shortness of breath, arm pain or numbness, nausea or vomiting, neck, jaw or shoulder pain, epigastric pain, sweating, weakness (less common symptoms); 20.36% correctly reported four or more heart attack symptoms, only 7.4% knew all the correct heart attack symptoms, and 28.94% knew about reperfusion therapy for heart attack; 31.7% reported to call 120 or 999 while having a heart attack themselves; however 89.6% reported to call 120 or 999 when someone else is suffering from a heart attack. Very old persons and those with health insurance coverage, high education level, high household income, longer living in Beijing and previous experience with heart disease had greater knowledge of heart attack symptoms. CONCLUSIONS: Public knowledge of common heart attack symptoms as well as less common heart attack symptoms is deficient in Beijing residents. But their knowledge of calling emergency medical services when someone is having a heart attack is relatively adequate. Public health efforts are needed to increase the recognition of the major heart attack symptoms in both the general public and groups at high risk for an acute cardiac event, especially in socioeconomically disadvantaged subgroups, including persons with low education level, low household income, and no health insurance coverage.
