We conducted this research to evaluate the severity of coronary artery disease with the number of live births and breastfeeding duration.</span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Methods:</span></i></b> Patients aged 30-50 years old with positive exercise tests or evidence of cardiac ischemia who were candidates for coronary angiography were included. All the participants had at least one child. Syntax score was used to evaluate the severity of coronary arteries.</span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Results:</span></i></b> Mean number of children was 3.72&plusmn;1.85, in those patients with <2 live births no one had a syntax score&ge;1, but in the>5 live births group most patients had a syntax score&ge;1. In patients with zero syntax score, it was estimated as 4.91&plusmn;39.7; in patients with 1&le; syntax score, it was 4.48&plusmn;7.29 (P =0.76). Among patients with > 5 birth lives, those with higher syntax scores had older ages (P=0.497). After adjusting age, the association between live births and syntax score became non-significant (P=0.850).</span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Conclusion</span></i></b><i><span style="color:blue">:</span></i> By increasing the number of live births >5, the severity of coronary artery disease, increases. However, this association was not significant after adjusting the age of patients. </span></span></span><br> &nbsp; breastfeeding, livebirths, syntax score, coronary artery disease, pregnancy 430 438 http://caspjim.com/browse.php?a_code=A-10-3108-1&slc_lang=en&sid=1 Mir-Hossein Seyyed-mohammadzad mohammadzad.h@umsu.ac.ir 100319475328460048917 100319475328460048917 No Department of Cardiology, Urmia University of Medical Sciences, Urmia, Iran Dorsa Kavandi Kavandidrs@gmail.com 100319475328460048918 100319475328460048918 No Student Research Committee, Zanjan University of Medical Sciences, Urmia, Iran Mohammad Jalili mohammad74jalili@gmail.com 100319475328460048919 0009-0008-2292-5932 No Student Research Committee, Urmia University of Medical Sciences, Urmia, Iran Sahar Ghodratizadeh drs_ghodratizadeh@yahoo.com 100319475328460048920 100319475328460048920 No Department of Anesthesiology, Urmia University of Medical Sciences, Urmia, Iran Amir Mikaeilvand A.mkvnd.cardio@gmail.com 100319475328460048921 100319475328460048921 No Department of Cardiology, Urmia University of Medical Sciences, Urmia, Iran Hanieh Sakha H.dsakha@yahoo.com 100319475328460048922 100319475328460048922 No cardiovascular research center, Tabriz University of Medical Sciences, Tabriz, Iran Reza Hajizadeh hajizadh.reza@gmail.com 100319475328460048923 100319475328460048923 Yes Department of Cardiology, Urmia University of Medical Sciences, Urmia, Iran
