Description
Technical Field
The invention relates to the technical field of cardiovascular function assessment, in particular to a cardiovascular function assessment system.
Background
Coronary Artery Disease (CAD) is the leading cause of death and disability in developed countries, accounting for over one third of the total deaths in the population over the age of 35. Among them, Acute Coronary Syndrome (ACS) has evolved into a useful term referring to a series of conditions that are linked to acute myocardial ischemia and/or myocardial infarction due to sudden reduction of coronary blood flow. If the electrocardiogram is unchanged and the cardiac enzymes are not yet changed, it is usually listed as "possible ACS". Patients suspected of ACS must be evaluated clinically quickly to distinguish which people have life threatening emergencies and which people are just the cause of benign.
A 12-lead electrocardiogram is the most common and convenient examination and should generally be performed within 10 minutes of the patient's arrival at the emergency room and to differentiate between symptoms of chest discomfort in the patient to assess whether there is cardiac ischemia or injury. However, electrocardiograms may be relatively normal or initially undiagnostic; if this is the case, the ECG examination should be repeated (e.g., at 15 to 30 minute intervals during the first hour), especially if symptoms occur again. However, ACS is not excluded even from normal electrocardiograms (the incidence of this is 1%
6%). In addition, most patients who arrive at the emergency room due to chest pain are not ACS and have a low risk of morbidity and mortality. Therefore, there is a need to employ sensitive screening methods to differentiate between needsPatients who receive more invasive examinations or more expensive examinations or interventions and allow those patients who do not need further examinations to leave early without being left in the emergency room.
The exercise Electrocardiogram (ECG) test is still the most common CAD screening test at present; however, their diagnostic accuracy is low (especially in women, more functionally impaired subjects or patients after revascularization) and even forbidden in ACS. The diagnosis accuracy of the induced myocardial perfusion photography (MPI) or the coronary tomography (CCTA) is better than that of the exercise electrocardiogram test. However, due to their ionizing radiation and high cost, they are not worth using in symptomatic patients with low probability of CAD development.
