Mismatch of presenting symptoms at first and recurrent XXXX . From the MONICA/KORA Myocardial Infarction Registry.

@entity1 @entity390 @entity6 @entity391 @entity1188 @entity158 @entity583
BACKGROUND: It is unknown whether the symptoms of first and recurrent @entity583 ( @entity583 ) are similar in the same @entity1 . This study examined the frequency of symptom mismatch, which factors are associated with a symptom mismatch and how symptom mismatch is related to 28-day case fatality. DESIGN: Observational study. METHODS: The sample consisted of 1282 @entity1 with a first and recurrent @entity583 , recruited from a population-based @entity583 registry, 1985-2011. Occurrence of 11 symptoms was recorded in first and recurrent @entity583 using standardized @entity1 interview. Logistic regression modelling adjusted for demographic and clinical variables was applied. RESULTS: Mismatch was highest for dyspnoea (40.6%) and lowest for chest symptoms (10.4%). Compared with @entity1 , @entity1 were less likely to have a mismatch of @entity158 between the shoulder blades (odds ratio (OR) 0.58, 95% confidence interval (CI) 0.43-0.79), @entity158 in the throat/jaw (OR 0.67, 95% CI 0.50-0.91), @entity390 (OR 0.62, 95% CI 0.47-0.82), @entity391 (OR 0.50, 95% CI 0.36-0.71), or fear of death (OR 0.71, 95% CI 0.53-0.94), or to have three or more mismatching symptoms (OR 0.60, 95% CI 0.45-0.79). @entity1 with @entity6 were more likely to have a mismatch in chest symptoms, whereas @entity1 with hyperlipidaemia or @entity1 who received any revascularization therapy at first @entity1188 were significantly less likely to have a mismatch of chest symptoms. Twenty-eight-day case fatality significantly increased with the number of mismatching symptoms (OR 1.14, 95% CI 1.02-1.28). CONCLUSIONS: @entity1 with @entity583 may benefit from information about the possibility that a recurrent @entity1188 may be associated with different symptoms.
