摘要

The device has a hemodynamic sensor (56) providing a hemodynamic signal representative of myocardial contractility. A cardiac contractility evaluation unit (54) provides a cardiac contractility index by applying a group (58) of contractility criteria S`1, S`2 to the signal. A cruciate analysis unit (60) receives a clinical state index and the contractility index as input and provides a composite preventive alert signal e.g. Boolean signal, as a function of values respectively taken by the indexes, where the clinical state index is provided by a patient`s clinical state evaluation unit (50).
