Objective To investigate the effect of coronary artery bypass grafting (CABG) on patients with coronary heart disease and giant left ventricular dimension but without aneurysm. Methods The clinic data of 51 consecutive patients with coronary heart disease accompanied by enlarged left ventricle dimension without aneurysm, including 50 males and 1 female, undergoing CABG between January 2004 and December 2006 in Nanjing First Hospital of Nanjing Medical University was retrospectively reviewed. The patients were at the age of 54-61 years with an age of 57.5±3.2 years. All patients received CABG, combined with aortic valve replacement in 7, mitral valve replacement in 16, mitral valvoplasty in 17 and tricuspid valvoplasty in 7. After surgery, perioperative complications and mortality were closely observed and followup for a period of 37 months was carried out. Results The number of distal anastomoses per patient was 2.0-4.0(3.8±1.1). Four patients died perioperatively (7.8%), among whom 2 died from malignant ventricular fibrillation, 1 from acute kidney failure and 1 from stroke caused by severe low cardiac output syndrome. All other patients were discharged from hospital with good recovery. After operation, 5 patients had atrial fibrillation and 11 had ventricular fibrillation, but all of those patients survived after proper treatment. The followup period for 47 patients was 37-49 months (43±11months), with a followup rate of 100%. No death occurred during the follow-up. Ultrasound cardiography in the followup period showed that there was a decreased left ventricular enddiastolic dimension (59±2 mm vs. 68±5 mm; t=7.320, Plt;0.05) and an improved left ventricular ejection fraction (45%±17% vs. 34%±15%; t=4.770, Plt;0.05) compared with those before operation with statistical significance. Conclusion CABG is an effective surgical procedure in the treatment of coronary heart disease with giant left ventricular dimension but without aneurysm.
ObjectiveTo evaluate the short- and mid-term outcomes of sequential anastomosis and simple anastomosis of saphenous vein in off-pump coronary artery bypass grafting.MethodsThe clinical data of 438 patients who underwent sequential anastomosis of saphenous vein and 165 patients who underwent simple anastomosis of saphenous vein from 2015 to 2018 in Daxing Teaching Hospital were retrospectively analyzed. After propensity score matching, 130 pairs of patients were included in the sequential anastomosis group [78 males and 52 females, aged 60 (52, 68) years] and simple anastomosis group [80 males and 50 females, aged 61 (52, 70) years]. The short- and mid-term clinical outcomes were compared.ResultsThe two propensity score-matched groups had similar baseline clinical data. No significant difference was found between sequential anastomosis and simple anastomosis groups in the in-hospital outcomes, including in-hospital death (1.5% vs. 1.5%, P=1.000), the incidence of complications (4.6% vs. 6.2%, P>0.05), and the mean flow of grafts (30.0±11.8 mL/min vs. 28.0±9.5 mL/min, P=0.597). The operation time of the sequential anastomosis group was shorter than that of the simple anastomosis group (142.5±21.2 min vs. 186.3±27.6 min, P<0.001). The drainage of the sequential anastomosis group was less than that of the simple anastomosis group (204.7±39.6 mL vs. 271.3±48.3 mL, P<0.001). The follow-up time was 12-60 (28.3±8.9) months, during which the mortality of the two groups was not statistically different (3.2% vs. 4.0%, P=0.796).ConclusionThe saphenous vein sequential anastomosis of saphenous vein is superior to the simple anastomosis. Sequential anastomosis technique can reduce aortic anastomosis, shorten operation time, and reduce bleeding drainage during off-pump coronary artery bypass grafting. The short- and mid- term clinical effects are satisfactory.

Methods 194 patients with CHD and 86 nonCHD patients were selected through coronary angiography in patients with essential hypertension. CHD group was divided into three subgroups including a single branch, doublebranch and multivessel disease. Intimamedia thickness (IMT) of carotid artery and carotid bifurcation, grade score, Crouse score, serum uric acid concentrations were detected in patients with coronary heart disease and control group. Results IMT of carotid artery and carotid bifurcation, grade score,crouse score, serum uric acid concentrations were higher in CHD group than that in control group, and the difference was statistically significant. In the CHD group, ultrasound parameters of carotid artery and serum uric acid increased with the increase in branch lesions (Plt;005 or 001). Conclusions Carotid IMT, grade score, Crouse score, serum uric acid concentration relate to coronary heart disease, which is an independent risk factor for coronary heart disease, respectively.
Coronary heart disease with gastrointestinal bleeding is common in clinical practice. The disease is dangerous and has a high mortality rate. This article will review the risk factors for coronary heart disease with gastrointestinal bleeding (including Helicobacter pylori infection, long-term use of antiplatelet drugs and combined anticoagulation drugs), blood transfusion strategies (including hemoglobin transfusion thresholds and platelet transfusion strategies), and the management of antithrombotic drugs after bleeding (including the management of antiplatelet drugs and the management of anticoagulation combined with antiplatelet drugs). The purpose is to provide a theoretical basis for the diagnosis and treatment of coronary heart disease with gastrointestinal bleeding.
ObjectiveTo systematically review the relationship between systemic immune inflammatory index (SII) and the prognosis of coronary heart disease. MethodsThe CNKI, VIP, CBM, WanFang Data, PubMed, EMbase, Web of Science, Ovid, Cochrane Library and Scopus databases were electronically searched to collect cohort studies related to the relationship between SII and the prognosis of patients with coronary heart disease from inception to December 10, 2022. Two researchers independently screened the literature, extracted the data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.3 and Stata 15.0 software. ResultsA total of 7 cohort studies involving 18 413 patients were included. The results of meta-analysis showed that the group of high level SII was higher risk of major adverse cardiovascular events (MACE) (OR=2.2, 95%Cl 1.5 to 3.3, P<0.01), all-cause death (OR=2.0, 95%Cl 1.1 to 3.4, P=0.02), and cardiogenic death (OR=2.4, 95%Cl 1.5 to 3.9, P<0.01) than the group of low level SII. However, no significant difference was found in the risk of re-hospitalization for heart failure. ConclusionThe current evidence shows that high levels of SII can increase the risk of MACE, all-cause death and cardiogenic death in patients with coronary heart disease. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
Objective To investigate the characteristics of blood pressure and coronary artery impairment in patients with essential hypertension (EH) combining coronary heart disease (CHD). Methods A total of 358 patients with EH combining CHD and other 144 patients with CHD were measured with ambulatory blood pressure monitoring (ABPM), and the parameters of ambulatory blood pressure were analyzed. All the patients underwent coronary angiography. The severity of coronary artery stenosis was evaluated in accordance with the number of impaired arteries. Results Compared to the patients with simplex CHD, those with EH combining CHD had much heavier artery stenosis and more diffuse lesions, with significant differences (χ2=6.03, P=0.019). The 24h systolic blood pressure (SBP), day SBP, night SBP, 24h pulse pressure (PP), day PP and night PP were higher in the patients with EH combining CHD compared to those of the patients with simplex CHD (The t values were 2.580, 2.045, 2.675, 2.037, 2.601, and 1.995, respectively, while the P values were 0.015, 0.037, 0.009, 0.041, 0.017, and 0.047, respectively). Conclusion Compared to the patients with simplex CHD, the patients with EH combining CHD suffer from much severe coronary artery impairment, so a good controlling of blood pressure is advisable to improve the coronary artery impairment for the patients with EH combining CHD.

Surgical Therapy for Valve Diseases Combined with Coronary Heart Diseases in Patients Over or Below 70 Years Old YU Lei, GU Tianxiang, SHI Enyi, XIU Zongyi, FANG Qin, ZHANG Yuhai. (Department of Cardiac Surgery, The No. 1 Hospital of China Medical University, Shenyang 110001, P.R. China)Corresponding author: GU Tianxiang, Email: cmugtx@sina.comAbstract： 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±14, 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.
Objective To investigate the changes and significance of serum inflammatory factors in coronary heart disease ( CHD) patients with obstructive sleep apnea-hypopnea syndrome ( OSAHS) , and the treatment effects of continuous positive airway pressure( CPAP) . Methods A total of 76 CHD patients in Renmin Hospital of Wuhan University from October 2007 to October 2008 were enrolled. Polysomnography ( PSG) was performed in these CHD patients to identify if they were complicated by OSAHS. The levels of inflammatory factors including TNF-α, IL-6, high sensitive C-reactive protein ( hs-CRP) in serum were determined in the CHD patients and 23 normal subjects. The CHD patients with moderate-severe OSAHS ( AHI≥15 episodes/hour) were treated by Auto-CPAP for 3 months and all parameters above were measured again. Results There were 41 /76 ( 53. 9% ) of CHD patients had moderate-severe OSAHS and were treated with CPAP. The levels of TNF-α, IL-6 and hs-CRP were significantly higher in the CHD patients than those in the normal controls ( all P lt; 0. 01) , and were significantly higher in moderate-severe OSAHS patients than those in the non-OSAHS CHD patients. Auto-CPAP ventilation significantly decreased the levels of inflammatory factors in the CHD patients with moderate-severe OSAHS. Conclusions An obvious proinflammatory state is detected in CHD patients, and is aggravated with OSAHS. CPAP is a useful treatment for CHD patients with mediate to severe OSAHS.
Objective To evaluate and select essential medicine for the treatment of coronary heart disease by means of evidence-based approaches based on the burden of disease for township health centers located in eastern, central and western regions of China. Methods By means of the approaches, criteria, and workflow set up in the second article of this series, we referred to the recommendations of evidence-based or authority guidelines from inside and outside China, collected relevant evidence from domestic clinical studies, and recommended essential medicine based on evidence-based evaluation. Data were analyzed by Review Manager (RevMan) 5.1 and GRADE profiler 3.6 to evaluate quality of evidence. Results (1) 11 clinical guidelines on coronary heart disease were included, three of which are evidence-based guidelines. (2) Totally, those guidelines contained 61 medicines (of 13 classes). (3) According to WHOEML (2011), NEML (2009), CNF (2010), other guidelines and the quantity and quality of evidence, we made a b recommendation for nitroglycerin, isosorbide dinitrate, metoprolol, nifedipine, verapamil, enalapril and aspirin as essential medicine for coronary heart disease. We made a weak recommendation for amlodipine, clopidogrel, heparin, propranolol, simvastatin and streptokinase. (4) 13 recommended medicines have been marketed in China and their prices were affordable. (5) Results of domestic low-quality studies indicated that nitroglycerin, isosorbide dinitrate, metoprolol, aspirin and heparin were effective for coronary heart disease. We didn’t find systematic reviews or pharmacoeconomic studies on the recommended medicines in Chinese literature databases. Conclusion For coronary heart disease: (1) We offer a b recommendation for nitroglycerin, isosorbide dinitrate, metoprolol, nifedipine, verapamil, enalapril and aspirin and a weak recommendation for propranolol, amlodipine, clopidogrel, heparin, simvastatin and streptokinase. (2) There is lack of high-quality evidence from relevant domestic studies, especially on pharmacoeconomic evaluation. (3) We propose that more studies should be carried out on clinical guideline of coronary heart disease and pharmacoeconomic comparison should be also made between recommended medicine and medicine of the same class.
