The purpose of this study was to understand the trajectory of prehospital delay in patients with acute myocardial infarction (AMI) in the Japanese health care system, which offers patients a choice between seeking treatment in a neighborhood clinic/small hospital (clinic group) or a large hospital with comprehensive cardiac services, including a cardiac catheterization laboratory (hospital group). ⋯ Findings support the need for public education in Japan that focuses on the appropriate response to AMI symptoms. Moreover, regional AMI networks need to be instituted to provide for early transfer for PCI from clinic/small hospitals to tertiary centers.

To investigate the predictive value of asymptomatic cervical bruit for detecting internal carotid artery disease in consecutive patients undergoing coronary artery bypass grafting (CABG). ⋯ Asymptomatic cervical bruit proved a highly specific clinical sign for detection of internal carotid artery stenosis, whether haemodynamically significant (> or = 50%) or otherwise, in patients undergoing myocardial revascularisation. This was matched by a high negative predictive value and overall accuracy for flow limiting atheroma (> or = 50% stenosis). Yet, steering carotid investigations on the basis of cervical bruit alone would result in > or = 80% internal carotid artery stenosis remaining undetected in 3% of overall patients, in whom cervical bruit is absent.
