• Class I: normal blood river behavior. Rattles in the lung are not provable, kardiale ejection achievement and pressure in the lung containers lie in the physiological range.
• Class II: the filling pressure of the Herzkammer is increased, the ejection achievement however normal. By the high filling pressure it comes to blood back pressure into the lung containers, a pulmonary edema can form, pulmonale rattles is present. The body periphery is normally supplied.
• Class III: normal filling pressure of the left chamber, therefore no blood back pressure in the lung, no pulmonary edema and no pulmonalen rattles. The decreased heart ejection achievement leads however to a Unterversorgung of the periphery.
• Class IV: increased filling pressure of the chamber, decreased heart ejection achievement. The lung containers and Unterversorgung of the periphery comes to blood back pressure into. A cardiogenic shock is the result.

The Forrester classification will related, in order to steer as optimal intensive-medical a therapy of the acute heart insufficiency as possible. Thus Vasodilatatoren lead such as Nitroglycerin and Molsidomin with patients with an acute cardiac infarct of the Forrester class II to a favourable decrease of the lung congestion without unfavorable changes. With patients of the class III however Vasodilatatoren cause a waste of the heart minute volume, with them are rather a careful volume supply meaningful.
