<p class="abstract"><strong>&nbsp;&nbsp; </strong><strong>BACKGROUND:</strong> Some studies showed that smoking follows an upward trend in Asian countries as compared with other countries. The purpose of this study was to examine the effect of cigarette smoking on cardiovascular diseases and risk factors of atherosclerosis in patients with hypertension.</p> <p class="abstract"><strong>&nbsp;&nbsp; </strong><strong>METHODS:</strong> This study was conducted on 6123 men residing in central Iran (Isfahan and Markazi Provinces) that participated in Isfahan Healthy Heart Project (IHHP). Subjects were randomly selected using cluster sampling method. All the subjects were studied in terms of their history of cardiovascular disease, demographic characteristics, smoking, blood pressure, physical examination, pulse rate, respiratory rate, weight, height, waist circumference, and blood measurements including LDL-C, HDL-C, total cholesterol, triglyceride, fasting blood sugar and 2-hour post prandial test.</p> <p class="abstract"><strong>&nbsp;&nbsp; RESULTS: </strong>While 893 subjects suffered from hypertension, 5230 subjects were healthy. The hypertension prevalence was 2.5 times more in urban areas compared to rural areas that showed a significant difference as it increased to 3.5 times smoking factor was considered. The prevalence of risk factors of atherosclerosis and also cardiovascular complications in patients with hypertension were significantly higher than healthy people. Furthermore, they were higher in smokers with hypertension and those exposed to the cigarette smoke than nonsmokers.</p> <p class="abstract"><strong>&nbsp;&nbsp; </strong><strong>CONCLUSION:</strong> Smoking and passive smoking had an increasing effect on the prevalence of risk factors of atherosclerosis and consequently the incidence of cardiovascular diseases in patients with hypertension.</p> <p class="abstract">&nbsp;</p><table cellspacing="0" cellpadding="0" align="left"><tbody><tr><td width="35" height="12">&nbsp;</td></tr> <tr><td>&nbsp;</td> <td>&nbsp;</td></tr></tbody></table><p class="abstract">&nbsp;</p> <br /> <p class="abstract"><strong>Keywords:</strong> Hypertension, Cigarette Smoking, Cardiovascular Disease, Risk Factor.</p>
