  • Surgical Therapy for Valve Diseases Combined with Coronary Heart Diseases in Patients Over or Below 70 Years Old

    Surgical Therapy for Valve Diseases Combined with Coronary Heart Diseases in Patients Over or Below 70 Years Old YU Lei, GU Tianxiang, SHI Enyi, XIU Zongyi, FANG Qin, ZHANG Yuhai. (Department of Cardiac Surgery, The No. 1 Hospital of China Medical University, Shenyang 110001, P.R. China)Corresponding author: GU Tianxiang, Email: cmugtx@sina.comAbstract: Objective To summarize the experiences of valve replacement combined with coronary artery bypass grafting (CABG) in senile patients by comparing clinical outcomes of valve diseases combined with coronary heart diseases in patients over or below 70 years old. Methods We retrospectively analyzed the clinical data of 49 patients who received valve replacement combined with CABG in our department from May 1999 to December 2007. Based on the age, the patients were divided into ≥70 years group (17 cases) with its patients at or above 70 years old and lt;70 years group (32 cases) with its patients younger than 70. The percentage of chronic obstructive pulmonary diseases (COPD) before surgery in ≥70 years group was higher than that in lt;70 years group(Plt;0.05). No significant difference was found in the other relevant factors between the two groups. The clinical index of patients in the two groups were compared and analyzed. Results There were significant differences between the two groups in such factors as the percentage of biovalve use (82.4% vs. 12.5%, χ2=23.311, P=0.000), the time of mechanic ventilation (34.5±29.3 h vs. 18.0±16.1 h, t=-2.542,P=0.014), the time of ICU stay (4.4±1.5 d vs. 3.3±0.7 d, t=-3.522, P=0.001), the time of hospital stay (21.4±7.7 d vs. 18.1±1.8 d, t=-2.319, P=0.025), the percentage of IABP use (29.4% vs. 6.3%, χ2=4.862, P=0.037), the percentage of pulmonary function failure (35.3% vs. 6.3%, χ2=6.859, P=0.009), the percentage of acute renal failure (23.5% vs. 3.1%, χ2=5.051, P=0.025), and the percentage of cerebrovascular accident (11.8% vs. 0.0%, χ2=3.933, P=0.048). There was no significant difference between the two groups in factors like the anastomosis of distal graft (2.5±3.1 vs. 2.4±14, t=0.301, P=0.758), the time of aortic occlusion (89.3±25.4 min vs. 88.5±31.0 min, t=0.108,P=0.913), the time of cardiopulmonary bypass (144.6±44.8 min vs. 138.3±52.9 min, t=0.164, P=0.871) and the mortality (5.9% vs. 6.3%, χ2=0.002,P=0.959). The perioperative myocardial infarction rate was zero in both groups. ≥70 years group patients were followed up for 2 months to 9 years with only 1 case missing. One patient who had undergone mechanic valve replacement died of cerebral hemorrhage 1.5 years after operation. Two died of heart failure and lung cancer 3 months and 6 years after operation respectively. For all the others, the cardiac function was at class Ⅰ to Ⅱ and their life quality was significantly improved. The follow up time of lt;70 years group was 1 month to 6 years and 5 cases were missing. Four patients who had undergone mechanic valve replacement died of complications in relation to anticoagulation treatment. One died of severe low cardiac output. Another died of traffic accident. Conclusion Surgery operation and effective perioperative treatment are key elements in improving surgery successful rate and decreasing mortality in patients with valve and coronary artery diseases. Valve replacement combined with CABG is safe for patients older than 70 years old.

  • Comparative Study between Offpump and Onpump Coronary Artery Bypass Grafting in the Patients of Multivessel Coronary Disease Below 70 Years Old

    Abstract: Objective To compare the therapeutic effects between offpump coronary artery bypass grafting (off-pump CABG) and onpump coronary artery bypass grafting (on-pump CABG) in the patients of multivessel coronary disease below 70 years old, in order to decide on the best surgery method. Methods From June 2007 to June 2009, 196 patients below the age of 70 underwent coronary artery bypass grafting (CABG), including 152 male patients and 44 female patients. The average age was 55.00 years old, ranging from 46 to 69 years. The patients were divided into two groups according to the methods of operation. There were 94 patients in the off-pump CABG group including 2 patients who were converted to the onpump CABG surgery because of the unstable hemodynamics. The other 102 patients were in the onpump CABG group. The type and number of the vessel grafts, the quantity of blood transfusion, intubation duration, length of stay in hospital, complications during perioperative period and mortality were compared between the two groups. Results In the offpump CABG group, 2 patients were converted to onpump CABG surgery because of the unstable hemodynamics, and 1 of them died from multiple organ failure. In the onpump CABG group, 2 patients died from severe low output syndrome and sudden heart arrest respectively. No significant difference was found in the vessel grafting materials, perioperative complications and mortality between the two groups (Pgt;0.05), while the number of anastomosis (3.22±0.65 vs. 4.52±1.11, t=9.807, P=0.000), the [CM(159mm]quantity of blood transfusion (312.57±305.26 ml vs. 744.86±279.37 ml, t=10.317, P=0.000),the intubation duration (10.71±5.32 h vs.17.12±4.67 h, t=8.683, P=0.000) and the length of stay in hospital (17.75±3.04 d vs. 21.24±6.46 d, t=4.782,P=0.000) in the off-pump CABG group were significantly lower or shorter than those in the on-pump CABG group. A total of 93 patients in the off-pump CABG group and 100 patients in the on-pump CABG group were followed up with the time periods ranging from 2 to 26 months. All patients survived without angina. Conclusion There is no significant difference in the early clinical therapeutic effects between off-pump CABG and onpump CABG in the patients of multivessel coronary disease below 70 years old, but revascularization in the on-pump CABG patients is better. So far, offpump CABG cannot replace on-pump CABG and more clinical trails are needed for evaluation of the longterm prognosis.
