RESUMO
The patterns of revascularisation with percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass graft (CABG) surgery in the GUSTO 1 trial patients in Australia are described. In comparison with rates documented in earlier trials of thrombolytic therapy in Australia, the rates of revascularisation post-thrombolysis increased by 50%, primarily due to a doubling in the rate of use of PTCA. However, the rates were low by international comparisons. There were marked variations in the rates of revascularisation between States, but no correlation with differences in mortality between States. The main predictors of post thrombolysis PTCA were prior angina, mild infarction and access to PTCA facilities.

In this graphite-furnace atomic-absorption spectrometric method for measuring manganese in whole blood, we use a pyrolytic platform to minimize interference by sample matrix. For optimal sample ashing we denature the sample within the furnace with nitric acid and use oxygen as the purge gas at low temperatures. The mean manganese concentration found in blood from 15 unexposed city dwellers was 215 (2 SD 135) nmol/L. By comparison, the range of manganese concentrations in blood sampled from a group of Australian aborigines living near a surface manganese ore deposit on Groote Eylandt, Northern Territory, was much higher (median 405 nmol/L, range 175 to 990 nmol/L).
