Rapid Classification and Treatment Algorithm of Cardiogenic Shock Complicating Acute Coronary Syndromes: The SAVE ACS Classification

Table 2

Frontline SAVE ACS classification.

	No shock	A	B	C	D	E
N (%)	163 (17.5%)	98 (10.4%)	287 (30.4%)	262 (27.7%)	109 (11.5%)	24 (2.5%)
SBP	≥90 mmHg	≥90 mmHg	Any	Any	Any	<90 mmHg
LV impairment	Mild	Mod/severe	Mod/severe	Mod/severe	Mod/severe	Severe
Lactate	<2	<2	<2	2–5	>5	>5
BE	>−0.5	>−0.5	<−0.5	<−0.5	<−0.5	<−4
30-day mortality (%)	1.2	4.1	13.6	29.4	64.2	87.5
30-day mortality (%) if not intubated	0.7	2.3	11.2	23.4	55.6	62.5

Data from 943 patients classified according to the SAVE criteria, AUC for 30-day mortality 0.814 (0.782 to 0.845), , SBP: systolic blood pressure, LV: left ventricle, BE: base excess, and AUC: area under the curve.
