近年来,吸烟对心血管疾病患者的影响已引起人们的广泛注意。许多国家的研究表明,吸烟者的周围血管疾病、冠心病、高血压病和脑血管病的发病率与死亡率均明显升高。尸检研究又显示,吸烟者的主动脉和冠状动脉粥样硬化比不吸烟者常见而严重。因此,一般认为.吸烟是很多心血管疾病的易患因素。为了从吸烟对微循环影响的角度探讨吸烟患者易患心血管病或加重病情的可能机理,吴良金等观察了40例长期吸烟的心血管病患者在连续吸烟2支 In recent years, the impact of smoking on patients with cardiovascular disease has attracted widespread attention. In many countries, studies have shown that smoker’s peripheral vascular disease, coronary heart disease, hypertension and cerebrovascular disease incidence and mortality were significantly increased. Autopsy studies have shown that smokers with aorta and coronary atherosclerosis than non-smokers common and serious. Therefore, it is generally believed that smoking is a predisposing factor for many cardiovascular diseases. In order to explore the possible mechanism of smoking susceptibility to cardiovascular disease or aggravating disease from the perspective of the impact of smoking on microcirculation, Wu Liangjin et al observed the long-term smoking in 40 patients with cardiovascular disease in two consecutive cigarettes
