Out of 102 patients with cardiac infarction admitted to the coronary care unit at this hospital and not treated with anticoagulants 30 (29%) developed isotopic evidence of deep vein thrombosis. Of the 65 smokers only 7 (11%) developed a deep vein thrombosis, whereas of the 37 non-smokers 23 (62%) developed a deep vein thrombosis. This difference is highly significant (P < 0.00001).
在这家医院入住冠心病监护病房且未接受抗凝治疗的102例心肌梗死患者中,有30例(29%)出现了深静脉血栓形成的同位素证据。在65名吸烟者中,只有7例(11%)发生了深静脉血栓形成,而在37名不吸烟者中,有23例(62%)发生了深静脉血栓形成。这种差异具有高度显著性(P < 0.00001)。
