- We describe the use of biochemical markers in the pre-hospital setting with regard to diagnostic accuracy for the detection of an acute myocardial infarction (AMI) and for prognosis in connection with acute chest pain. The sensitivity has been reported to be limited; blood sampling occurs very early and often prior to the release of biochemical markers into the circulation. The specificity was in some studies also limited, but this is more difficult to explain. New biochemical markers like human heart fatty acid binding protein (H-FACB) have shown improved diagnostic accuracy, in the pre-hospital setting, in one small pilot study compared with traditional biochemical markers like troponins, creatine kinase (CK-MB) and myoglobin. However, in a recent small study, the sensitivity for troponin I (when a low decision limit for myocardial damage was used), when analysed prior to hospital admission, was reported to be very high. The latter data need to be confirmed in larger studies and various biochemical markers reflecting various pathophysiological aspects of the disease need to be tested before the analysis of any marker can be recommended for use in the pre-hospital setting of a suspected AMI.

- OBJECTIVETo examine the relationship between country of birth and the utilization of coronary angiography, percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) after a first-time myocardial infarction (MI).DESIGN, SETTING AND PATIENTS117,494 MI patients of all ages who were admitted to coronary care units between 2001 and 2009 in Sweden were followed-up for three months after admission.MAIN OUTCOME MEASURESUndergoing coronary angiography, PCI or CABG after first-time MI.RESULTSproportion of patients undergoing angiography and PCI increased whereas proportion of patients undergoing CABG also delay time for all three procedures decreased over the study period. The proportion of women undergoing any of the three procedures was markedly lower and delay time longer than those of men regardless of study period and migration background. Overall foreign-born first MI patients had higher rate of angiography (HR = 1.30, 95% CI: 1.27-1.33), PCI (HR = 1.27, 95% CI: 1.24-1.30) and CABG (HR = 1.21, 95% CI: 1.15-1.28) compared with Sweden born first MI patients. After controlling for potential confounding factors in multivariable models, the overall differences vanished for angiography and reduced markedly for PCI and CABG. However, multivariable stratified analysis by specific country of birth yielded higher rate of angiography among men born in Uganda (HR = 2.11, 95% CI: 1.00-4.43) and Peru (HR = 1.98, 95% CI: 1.07-3.68) and lower rate among men born in Croatia (HR = 0.71, 95% CI: 0.52-0.99) and women born in Thailand (HR = 0.49, 95% CI: 0.35-0.94). PCI adjusted rates were higher among women born in Palestine state (HR = 2.44, 95% CI: 1.15-5.16), Iraq (HR = 1.34, 95% CI: 1.04-1.74) and Poland (HR = 1.21, 95% CI: 1.02-1.44) and rate of CABG was higher among immigrants from some parts of Asia, including men born in Sri Lanka (HR = 3.19, 95% CI: 1.43-7.12), India (HR = 1.95, 95% CI: 1.21-3.14), Vietnam (HR = 2.65, 95% CI: 1.32-5.33), Palestine State (HR = 2.11, 95% CI: 1.06-4.24), and women born in Syria (HR = 2.36, 95% CI: 1.25-4.45), Iraq (HR = 1.74, 95% CI: 1.02-2.94), and Turkey (HR = 1.70, 95% CI: 1.03-2.79).CONCLUSIONSThe observed high rate of CABG for immigrants and particularly those born in some Asian countries was not explained by the potential confounding factors. A more severe coronary disease in this population might explain this high rate but needs further research. Awareness and subsequent intervention at earlier stage of coronary disease among immigrants could prolong their life and reduce the healthcare costs.
