Coronary Artery Bypass Graft in Six Members of a Family: A Case Series

Abstract: Coronary artery disease (CAD) is a multifactorial problem. Although hyperlipidemia (HLP), diabetes (DM), and hypertension (HTN) are known as the familial and cardiac risk factors, CABG is rare in the several members of a family. We reported the six members of a family who presented with MI and/or advanced angina pectoris during the 6 years. CABG(Coronary artery bypass graft) considered for all patients due to involvement in main coronary arteries and clinical presentation. The ejection fraction (EF) was varied between 25% to 70%. Beating heart cardiopulmonary bypass (beating heart CPB) and off-pump were chosen as surgical method. The mean duration of surgery was about 4 hours. The only post-operative complication was deep wound infected in a young man who was smoker and drug abuser. According to family relationship of patients and the high effect of genetic penetration, we presume the gene influence to incidence CAD and potential to undergoing CABG, in members of a special family.
