To determine the causes of pleural effusions in patients with heart failure, and the association of the characteristics of these statistics with the use of diuretics.
Eighty-one patients with a definite diagnosis of heart failure who underwent thoracentesis were evaluated. Fluids were classified as transudates or exudates using Light's criteria.
Forty-one effusions (in 34 patients) were transudates, and 54 (in 47 patients) were exudates. A specific cause was found for 32 of the exudates (27 patients); except for heart failure, no obvious cause was found for the remaining 22 fluids (20 patients). Exudates with a specific cause for an exudate were more likely to have at least two of Light's criteria (18 of 27 [67%]) than did exudates without a known cause (2 of 21 [10%]). Intravenous diuretic therapy in the 24 hours before thoracentesis was significantly more common among patients with exudates without a specific cause.
Patients with heart failure may have exudative pleural effusions without an obvious cause except heart failure.
确定心力衰竭患者胸腔积液的病因，以及这些统计特征与利尿剂使用之间的关联。
对81例确诊心力衰竭且接受胸腔穿刺术的患者进行评估。采用Light标准将胸腔积液分为漏出液或渗出液。
41例积液（34例患者）为漏出液，54例（47例患者）为渗出液。在渗出液中，32例（27例患者）发现了特定病因；其余22例积液（20例患者）除心力衰竭外未发现明显病因。有特定病因的渗出液比无已知病因的渗出液更有可能至少符合Light标准中的两条（27例中有18例[67%]，而21例中仅有2例[10%]）。在无特定病因的渗出液患者中，胸腔穿刺术前24小时内进行静脉利尿剂治疗的情况明显更为常见。
心力衰竭患者可能出现除心力衰竭外无明显病因的渗出性胸腔积液。
