Impending cardiac failure is often difficult to recognize and requires a multidisciplinary approach. Upon arrival in the emergency department, patients are promptly screened for potentially life-threatening conditions through a history and physical examination. In many cases, the diagnosis is not clear until confirmatory laboratory or imaging tests are performed. Unfortunately, patients can rapidly decompensate as this diagnostic information is being obtained. Emergent CT plays a key role in identifying conditions that may result in cardiovascular collapse, including severe congestive heart failure, myocardial infarction, cardiac tamponade, and impending cardiac failure. Characteristic imaging findings can prompt the physician to take immediate action and prepare for resuscitation.
即将发生的心衰往往难以识别，需要多学科方法。患者到达急诊科后，会通过病史和体格检查迅速筛查可能危及生命的情况。在许多情况下，直到进行了确诊的实验室或影像学检查，诊断才会明确。不幸的是，在获取这些诊断信息的过程中，患者可能会迅速失代偿。急诊CT在识别可能导致心血管崩溃的情况方面起着关键作用，包括严重充血性心力衰竭、心肌梗死、心脏压塞和即将发生的心衰。特征性的影像学表现可促使医生立即采取行动并为复苏做好准备。
