人类吸入可卡因和吸烟能增加心脏需氧代谢,或可能导致氧的供应减少。由于可卡因作为毒品广为滥用,引起不良反应甚多,尤其在吸烟者中,胸痛、心肌梗塞和猝死的发生率明显增加。本文评价了有或无冠心病者,经鼻吸入可卡因、吸烟或两者共用时对心肌需氧和冠脉内径大小的影响。 Human inhalation of cocaine and smoking can increase cardiac aerobic metabolism, or may lead to reduced oxygen supply. As cocaine is widely abused as a drug, it causes a lot of adverse reactions, especially among smokers, with a marked increase in the incidence of chest pain, myocardial infarction and sudden death. This article assesses the effects of both inhaled cocaine, cigarette smoking, or both on myocardial aerobic and intracoronary diameter with or without coronary heart disease.
