ABSTRACT
Cocaine use is associated with adverse events in nearly every organ system. Cardiovascular complications include hemorrhagic and ischemic stroke, aortic dissection, cardiomyopathy, accelerated coronary artery disease, myocardial infarction, and sudden cardiac death. Syncope may be the presenting symptom in these conditions. However, cocaine-induced bradyarrhythmias have been scarcely mentioned. As this case exemplifies, clinicians should be aware of this association when they evaluate syncope, especially in young patients.

A 78-year-old man presented with acute lupus pleuritis due to procainamide. The pleural fluid was a turbid, yellow exudate with a WBC count of 53,200/cu mm (70 percent polymorphonuclear leucocytes), LDH of 4,296 IU/L, and pH of 7.195. Although these fluid characteristics suggested pleural space infection, they were due to pleural inflammation from drug-induced lupus. LE cells were present in the fluid and results of microbiologic studies were negative. Clinical and roentgenographic improvement followed discontinuation of procainamide.
