A 5-year and 7-year follow-up study on 5249 Copenhagen men showed a relationship between smoking habits at the time of entry into the study and incidence of lethal and non-lethal myocardial infarction. With a relative risk of 4.2, heavy cheroot smokers had a higher risk of myocardial infarction than cigarette smokers (relative risk 2.1) and never-smokers. A multiple regression analysis indicates that cheroot smoking is an independent coronary risk factor.
一项针对5249名哥本哈根男性的5年和7年随访研究表明，在进入研究时的吸烟习惯与致命和非致命性心肌梗死的发生率之间存在关联。重度方头雪茄吸烟者发生心肌梗死的风险相对较高，相对风险为4.2，高于吸烟者（相对风险2.1）和从不吸烟者。多元回归分析表明，吸方头雪茄是一个独立的冠状动脉危险因素。
