These men formed the intervention group for the present follow-up study covering the subsequent 6 years. The reference group for the follow-up comprised 152 men who fulfilled the same inclusion critera for the original study as the intervention subjects, but who had been excluded from the study for non-medical reasons, mainly because they could not be pair-matched. Mortality statistics were collected, and a postal questionnaire on chest pain symptoms and physical activity was sent to all of the men 8 years after the start of the study. One CHD death and four other deaths occurred in the reference group, and one CHD and no other deaths in the intervention group. Severe chest pain possibly suggestive of myocardial infarction was more common in the reference group than in the intervention group, but no difference was found in angina pectoris symptoms. The level of recent physical activity or smoking did not affect the chest pain symptoms independently.<\/jats:p>","DOI":"10.1177\/140349488000800304","type":"journal-article","created":{"date-parts":[[2017,1,7]],"date-time":"2017-01-07T00:47:15Z","timestamp":1483750035000},"page":"99-104","source":"Crossref","is-referenced-by-count":0,"title":["Mortality and Incidence of Chest Pain after an Exercise Intervention Programme"],"prefix":"10.1177","volume":"8","author":[{"given":"Pekka","family":"Oja","sequence":"first","affiliation":[{"name":"From the Institute of Occupational Health, Helsinki"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kalevi","family":"Py\u00f6r\u00e4l\u00e4","sequence":"additional","affiliation":[{"name":"University of Kuopio, Kuopio"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Risto","family":"K\u00e4r\u00e4v\u00e4","sequence":"additional","affiliation":[{"name":"Communal Pension Institute, Helsinki"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sven","family":"Punsar","sequence":"additional","affiliation":[{"name":"Laakso Hospital, Helsinki"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1980,9,1]]},"reference":[{"key":"bibr1-140349488000800304","doi-asserted-by":"publisher","DOI":"10.1136\/pgmj.52.609.417"},{"key":"bibr2-140349488000800304","doi-asserted-by":"publisher","DOI":"10.1111\/j.0954-6820.1977.tb15750.x"},{"key":"bibr3-140349488000800304","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1971.00310240115015"},{"key":"bibr4-140349488000800304","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1971.00310200037002"},{"key":"bibr5-140349488000800304","doi-asserted-by":"publisher","DOI":"10.1126\/science.190.4216.764"},{"key":"bibr6-140349488000800304","doi-asserted-by":"publisher","DOI":"10.1177\/140349487800600307"},{"key":"bibr7-140349488000800304","unstructured":"Oja P.
