Blood pressure waveform analysis in cardiogenic shock & acute myocardial infarction

Cardiogenic shock(CS) is the main cause of death in patients with acute myocardial infarction. The definition of CS suggests an on/off phenomenon although CS is more likely to be a gradual phenomenon ranging from mild to severe CS. For this thesis a custom blood pressure analysis method is developed calculating pressure, time, slope and area parameters based on the detection of 5 markers in the blood pressure curve. In 9 parameters a difference was detected between one of the CS outcome groups. Relative dicrotic notch pressure, left-ventricular ejection time and absolute systolic area under the curve are significantly different between survivors and non-survivors. These are potential parameters in predicting outcome of patients with CS
