ABSTRACT

OBJECTIVE: We aimed to assess whether patients' knowledge about acute myocardial infarction (AMI) has an impact on the prehospital delay-time. METHODS: This investigation was based on 486 AMI patients who participated in the cross-sectional Munich-Examination-of-Delay-in-Patients-Experiencing-Acute-Myocardial-Infarction (MEDEA) study. A modified German-version of the ACS-Response-Index Questionnaire was used. Multivariate logistic-regression models were used to identify factors associated with knowledge-level as well as the impact of knowledge-level on delay-time. RESULTS: High AMI-knowledge shortened median delay-time in men (168[92-509] vs. 276[117-1519] mins, p=0.0069), and in women (189[101-601] vs. 262[107-951]mins, p=0.34). Almost half-of-patients (n=284,58%) demonstrated high AMI-knowledge. High-knowledge were independently associated with male-gender (OR=1.47[1.17-1.85]) and General-Practitioner as a knowledge-source (OR=1.42[1.14-1.77]). Old-age (OR=0.87[0.86-0.89]) and previous AMI-history/stent-placement (OR=0.65[0.46-0.93]) were significantly associated with lower-knowledge. Although the majority (476,98%) correctly recognized at least one AMI-symptom, 69(14.2%) patients correctly identified all AMI-symptoms. Additionally, one-in-three believed that heart-attack is always accompanied with severe chest-pain. Elderly-patients and women were more likely to be less-knowledgeable about atypical-symptoms (p=0.006), present with atypical AMI-presentation (p<0.001) and subsequently experience protracted delay-times (p<0.001). CONCLUSIONS: Knowledge of AMI-symptoms remains to be substandard, especially knowledge of atypical-symptoms. Knowledge is essential to reduce delay-times, but it is not a panacea, since it is not sufficient alone to optimize prehospital delay-times.

ABSTRACT

BACKGROUND: Scarce evidence yields conflicting results regarding the effect of prodromal chest pain (PCP) on pre-hospital delay during an acute myocardial infarction (AMI). We aimed to assess the impact of PCP on delay. METHODS: Data was collected on 619 ST-elevated MI patients from the multicenter Munich Examination of Delay in Patients Experiencing Acute Myocardial Infarction (MEDEA) study. Patients with any PCP (which was subdivided into undefined PCP, possible and definite angina) within a year before AMI were identified using the Rose questionnaire, administered in bedside interviews. The influence of PCP and its subdivisions (all compared to no PCP) was assessed using logistic regression (with cut-offs of 2 h, 6 h, and a 4-category ordinal outcome). RESULTS: Any type of PCP was reported by men (50.6%) more than women (34.6%) (OR=1.9; 95% CI: 1.3 to 2.8; p=.001). The median delay of patients with PCP was not significantly different to delay in patients with no PCP (p=.327). Prolonged delay times were observed in women with PCPs of lesser degree of cardiac confirmation, while the opposite was observed in men. In women, possible angina was more strongly associated with delay <2 h (OR=6.8; 95% CI=2 to 23.8) than any PCP (OR=2.6; 95% CI=1.2 to 5.7). CONCLUSIONS: For men, PCPs of increasing cardiac confirmation are associated with prolonged delay. For women, PCPs of lesser cardiac confirmation are more likely to lead to prolonged delay. Future studies should investigate mediating factors.
