Figure 1 Hazard Ratios for All 30-Day Survivors

Hazard ratios with (red circles) and without (blue squares) cardiogenic shock. Factors analyzed include baseline characteristics, cardiac history, treatment group, and procedures undergone during index hospitalization. All continuous variables (age, weight, height, heart rate, and systolic and diastolic blood pressure) were measured in units of 1 (e.g., respectively, 1 year, 1 kg, 1 cm, 1 beat/min, and 1 mm Hg), so that patients with a variable that measured 1 U greater than another patient had a hazard of mortality as reflected in the figure. For example, a nonshock 65-year-old patient had a 1.06 greater hazard of dying than a nonshock 64-year-old patient. BP = blood pressure; CABG = coronary artery bypass grafting; CVD = cerebrovascular disease; dia = diastolic; IABP = intra-aortic balloon pump; IV Hep = intravenous heparin; MI = myocardial infarction; PTCA = percutaneous transluminal coronary angioplasty; SK = streptokinase; SubQ Hep = subcutaneous heparin; sys = systolic; t-PA = tissue plasminogen activator.
