In a study involving over 100 patients, international scientists have used spectroscopy to find thecauseof patients' chest pain.rn'We started the study [as if looking] through the eyes of a doctor saying there is a symptom,' says Wolfgang Petrich from Roche Diagnostics, Mannheim, who led the investigation. The international team - from Germany, the US, Canada, Austria, Sweden and Spain - analysed serum samples using a combination of mid-infrared spectroscopy and statistical techniques. They found that they could identify particular shapes in the spectra of samples from patients with acute myocardial infarction (AMI) -heart cell death or damage brought about by a heart attack. This was in contrast to spectra from samples taken from patients with the same symptom of acute chest pain, but without AMI.
