Only nitrogen dioxide was linked to an increased risk of a hospital admission for cardiovascular problems, including heart failure, and an increased risk of a particular type of heart attack (non-ST elevation) in the MINAP
report also reveals that just 53 patients were last year treated with primary angioplasty in Wales - in England more than 3,000 people received the treatment.
For j variables, MINAP performs j-1 PCAs, extracts the largest component, and then computes average residual correlations among the variables.
The K1, PARAN, and MINAP procedures all suggested retaining the first two components, which accounted for 48 and 25 percent of the total variance in the seven indicators, respectively.
And, as First Minister Rhodri Morgan recovers at home after undergoing an emergency angioplasty to clear two partially blocked arteries, the MINAP report reveals that only two hospitals in Wales - Morriston Hospital, in Swansea, and the University Hospital of Wales, in Cardiff - are able to offer such a service.
Although the sixth MINAP report states that some improvements have been made in Wales in the last year - particularly in preventing a second heart attack - the nation is some three to four years behind England.
Myocardial Ischaemia National Audit Project (MINAP

report found the percentage of hospitals in England providing thrombolytic (clot-busting) treatment to 75% of their eligible patients within 30 minutes of the patient's arrival at hospital had increased from 80% to 89% since the last report in June 2004.
Welsh hospitals are lagging behind England, where three-quarters of hospitals have now achieved the national targets, according to the Myocardial Infarction National Audit Project (Minap) report.
This is the first time Welsh hospitals have been included in the Minap report and are thought to be two years behind English centres.
This may be the first year that Welsh hospitals have been included in the Myocardial Infarction National Audit Project (Minap) data, but this will not be the first year that a heart attack patient needs lifesaving, clot-busting drugs.
Wales must move forward from the sorry position it finds itself today in the Minap report.
