The Beta Blocker Heart Attack Trial (BHAT) recruited 3837 patients who within the previous 5-21-day period had experienced a myocardial infarction. The purpose of the trial was to test the efficacy of propranolol in decreasing total mortality after such an event. Recruitment was carried out over a 28-month period and involved 31 clinics, 134 hospitals, and 136 acute coronary care units. Of the 157,771 patients admitted to these units, 16,358 met the BHAT criteria for a myocardial infarction, and 23% of those eligible were ultimately randomized. The use of a coronary care unit log was helpful for tracking patients to maximize recruitment and to provide information in regard to the universe from which patients were recruited.
β受体阻滞剂心肌梗死试验（BHAT）招募了3837名在过去5至21天内经历过心肌梗死的患者。该试验的目的是测试普萘洛尔在此类事件后降低总死亡率的疗效。招募工作在28个月内进行，涉及31个诊所、134家医院和136个急性冠状动脉护理单元。在这些单元收治的157771名患者中，16358名符合BHAT心肌梗死标准，符合条件的患者中有23%最终被随机分组。使用冠状动脉护理单元日志有助于追踪患者，以最大限度地进行招募，并提供有关招募患者来源总体的信息。
