About

Ischemic heart disease is a major public health problem with high mortality rate despite the progress in management and the resources mobilized. The idea is that myocardial ischemia is generally associated with left ventricular dysfunction and, consequently, a possible alteration of the dp/dt index. As dp/dt could be assessed non-invasively by plethysmographic method, it is interesting to investigate its prognostic performance in patients with indifferentiate chest pain.

Full description

Ischemic heart disease remains a major public health problem. Despite all the advances in the prognostic approach to ischemic heart disease, the risk of occurrence of major cardiovascular events is not negligible. Several scores have been proposed for chest pain stratification risk, the most widely used are the TIMI and the GRACE scores.

The dP/dt max is therefore an excellent index of contractility, corresponding to the maximum level of tension developed by an isolated cardiac muscle during the isovolumic contraction phase.

the investigator theorized that a less value of dp/dt would be associated with more major cardiovascular events (MACE), because ischemia reduces myocardial contractility.

The current study describes non-invasive plethysmographic dp/dt changes, which could be used as a prognostic marker in patients presenting at the emergency department with acute chest pain.
