A polygraph study of ischemic heart disease: short-term prognosis of acute myocardial infarction based on early modifications of isometric contraction time.
The authors have explored the early modifications of systolic time intervals in 90 patients hospitalized as emergency cases for acute myocardial infarction. From analysis and interpretation of the collected data they conclude that such modifications have considerable prognostic value. All patients fitting the specifications of NYHA classes I and II, but at the same time showing a shortening of the isometric contraction time to less than 39 +/- 1.4 ms turned out to constitute a high-risk group for the development of major mechanical and electrical complications in the next 2 weeks.
