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.
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 analyze the short-term clinical efficacy and prognosis of one-stop transcatheter aortic valve replacement (TAVR)+percutaneous coronary intervention (PCI) in the treatment of aortic valve disease with coronary heart disease. MethodsThe clinical data of patients with aortic valve disease complicated with coronary heart disease who underwent one-stop TAVR+PCI treatment at the Department of Cardiovascular Surgery, the Second Hospital of Hebei Medical University from January 2018 to June 2023 were retrospective analyzed. The preoperative and postoperative clinical data were compared, and 1-month follow-up results were recorded. ResultsA total of 37 patients were enrolled, including 22 males and 15 females, with an average age of 69.14±6.47 years. Thirty-six patients recovered and were discharged after the surgery, and 1 (2.7%) patient died during the surgery. Self-expanding TAVR valves were implanted through the femoral artery in all patients. One coronary artery was opened by PCI in 35 (94.6%) patients, and two coronary arteries were opened by PCI in 2 (5.4%) patients. All PCI opened arteries had a stenosis>70%. During the postoperative hospitalization, the complications included pulmonary infection in 11 (30.6%) patients, severe pneumonia in 10 (27.8%) patients, liver function injury in 14 (38.9%) patients, renal function injury in 5 (13.9%) patients, cerebral infarction in 1 (2.8%) patient, atrial fibrillation in 1 (2.8%) patient, ventricular premature beats in 2 (5.6%) patients, atrioventricular block in 2 (5.6%) patients, and complete left bundle branch block in 5 (13.9%) patients. The median postoperative ventilation assistance time was 12.0 (0.0, 17.0) h, the ICU monitoring time was 1.0 (0.0, 2.0) d, and the postoperative hospitalization time was 5.0 (4.0, 7.0) d. There was a significant improvement in the New York Heart Association cardiac function grading after surgery (P<0.001). After surgery, there were 21 (58.3%) patients had minor perivalve leakage, 6 (16.7%) patients had minor to moderate perivalve leakage, and no moderate or above degree of perivalve leakage. After one month of postoperative follow-up, 36 patients showed significant improvement in heart function. There were no patients with recurrent acute coronary syndrome, re-PCI, or cardiovascular system disease related re-hospitalization. ConclusionThe one-stop TAVR+PCI treatment for patients with aortic valve disease and coronary heart disease can obtain satisfactory short-term clinical efficacy, which is worth further trying and studying.
ObjectiveTo explore the relationship between pregnancy-associated plasma protein-A (PAPP-A) and different types of coronary heart disease (CHD) in Chinese. MethodsThe papers about the relationship between the PAPP-A level and coronary heart disease in Chinese published before December 2013 were searched from electronic databases, including PubMed, EMbase, China National Knowledge Infrastructure, Wanfang and VIP. Statistical analysis was carried out using Stata 12.0 software. ResultsA total of 44 papers were included in this meta-analysis. The number of cases was 3 628, including 1 137 stable angina pectoris (SAP) patients, 1 368 unstable angina pectoris (UAP) patients and 1 123 acute myocardial infarction (AMI) patients. The number of control was 1 177. This meta-analysis indicated that the levels of PAPP-A were higher in different types of CHD patients than those in the control group[SAP group:SMD=0.38, 95% CI (0.25, 0.50), P < 0.001; UAP group:SMD=2.84, 95% CI (2.36, 3.32), P < 0.001; AMI group:SMD=3.31, 95% CI (2.78, 3.85), P < 0.001, respectively]. The levels of PAPP-A were higher in AMI group than UAP group[SMD=0.56, 95% CI (0.33, 0.80), P < 0.001]. At the same time, the levels of PAPP-A in patients with disease of one, two and three coronary arteries were higher than those in the control group[SMD=2.40, 95% CI (1.49, 3.31), P < 0.001; SMD=2.27, 95% CI (1.44, 3.09), P < 0.001; SMD=2.30, 95% CI (1.35, 3.24), P < 0.001, respectively]. The levels of PAPP-A were higher in patients with disease of two arteries than in those of one artery[SMD=0.29, 95% CI (0.01, 0.58), P=0.042], but there was no significant difference between patients with disease of three arteries and those of 1 or 2 arteries(P > 0.05). ConclusionsThe levels of PAPP-A are significantly higher in CHD patients and are positively related with the severity of CHD. The levels of PAPP-A can be regarded as the indicator for judging the severity of CHD
Objective To compare the effectiveness and safety of angiotensin receptor blockers (ARB) and angiotensin-converting enzyme inhibitors (ACEI) for coronary heart disease (CHD). Methods Randomized controlled trials (RCTs) on ARB vs. ACEI in treating CHD were collected in databases including MEDLINE, EMbase, BIOSIS Previews, The Cochrane Library, CBM, VIP, WanFang Data and CNKI from inception to July 2011, and the references of the included articles were also retrieved. In accordance with the Cochrane Handbook 5.0.1, two reviewers independently evaluated the quality of articles, and extracted and cross-checked the data. Then meta-analysis was performed using RevMan 5.1.1 software. Results A total of 18 RCTs (17 660 cases) were included. The results of meta-analysis showed that there were no significant differences between the ARB group and the ACEI group in all-cause mortality (RR=1.04, 95%CI 0.98 to 1.11, P=0.20), cardiovascular mortality (RR=1.04, 95%CI 0.97 to 1.12, P=0.26), myocardial infarction (RR=0.98, 95%CI 0.92 to 1.05, P=0.59), hospitalization for heart failure (RR=1.14, 95%CI 0.97 to 1.32, P=0.11) and stroke (RR=0.93, 95%CI 0.80 to 1.08, P=0.34). However, the risk of adverse events causing drug discontinuation was significantly lower in the ARB group compared with the ACEI group (RR=0.77, 95%CI 0.67 to 0.89, P=0.000 3). Conclusion Current evidence suggests that ARB is as effective as ACEI in reducing the risk of all-cause mortality, cardiovascular mortality, myocardial infarction, hospitalization for heart failure and stroke in patients with coronary heart disease. Moreover, it is much better in tolerance. Because of the quality limitation and sampling size of the induced studies, this conclusion still needs to be further proved by more large-scale, multicenter and perspective clinical trials.
Objective To investigate the effect of combined carotid endarterectomy (CEA) and offpump coronary artery bypass grafting (OPCAB) on patients with carotid arteriostenosis and coronary heart diseases. Methods A total of 121 consecutive patients with carotid arteriostenosis and coronary artery diseases underwent CEA and OPCAB between January 2003 and December 2009 in Nanjing First Hospital of Nanjing Medical University. There were 81 males and 40 females, with their ages ranged from 62 to 72 years (67.2±4.5 years). All patients had 3vessel coronary artery lesions, and there were 3 cases of left main coronary artery lesion. Unilateral carotid arteriostenosis (≥50%) occurred in 95 patients, and bilateral (≥50%) in 26 patients. The occurrence of stroke, myocardial infarction, angina pectoris and other complications after operation was observed, and followup was carried out. Results All patients underwent unilateral CEA including 50 on the right side and 71 left. The mean block time of carotid artery in CEA was 20.5±7.0 minutes. The average number of distal grafts per patient in OPCAB was 2.9±0.3. None of the patients had stroke or myocardial infarction and no perioperative death occurred. Eightyseven patients felt well in terms of their neuropsycho symptoms; 32 felt no change; and 2 worsened. Follow-up was done for all the patients with a follow-up rate of 100%. The mean time of the follow-up was 67.5±12.5 months. During this period, none of the patients manifested stroke, myocardial infarction or neuropsycho symptoms. Conclusion Concomitant OPCAB and CEA is a safe and effective procedure in patients with carotid arteriostenosis and coronary artery diseases. It can reduce the rate of postoperative stroke significantly. However, longterm outcome of the procedure needs operative experience accumulation, longterm follow-up and observation, and serious research and illumination.
Objective To evaluate the effectiveness and safety of simvastatin 40 mg daily use in treatment of coronary heart disease. Methods The study was designed as before-after study in the same patients. One hundred and sixty seven patients with coronary heart disease were prescribed simvastatin 40 mg daily for 3 and 6 months. Total cholestero (TC), low-density lipoproteins cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerldes (TG), ALT and creatine kinase (CK) in serum before therapy and at the end of 3 months and 6 months treatment were dectected. Continuous data were analyzed by standard difference of blocked randomization and described by mean±SD. Dunnet-t test was used for multiple comparison of trial and control groups. Statistical difference was set up at P＜0.05. Success rate was assessed by chi square test at the end of 3 and 6 months treatment. Results Simvastatin 40 mg/d significantly decreased the level of TC (P＜0.000 5), LDL-C (P＜0.000 5), TG (P＜0.05), and could elevate HDL-C (P＜0.05). There were 39.5% of patients whose LDL-C reduced below 70 mg/dl. One patient whose CK raised 5.6 times of upper line of normal range and 4 patients whose ALT raised more than 2 times of upper line of normal range withdrew. The reliability of simvastatin 40 mg/d was relatively good. Conclusions Simvastatin 40 mg/d could significantly improve the lipid profile, and is relatively reliable in treatment of coronary heart disease.
Objective To assess the effectiveness and safety of tongxinluo capsule for coronary heart disease. Methods Both the randomized controlled trials (RCTs) and quasi-RCTs of tongxinluo capsule for coronary heart disease were collected through searching on computer from the following databases, The Cochrane Library (Issue 4, 2010), PubMed (2000 to April 2010), WanFang Data (1996 to April 2010), CNKI (1994 to April 2010) and VIP (1989 to April 2010). The trials selection based on inclusion and exclusion criteria, data extraction, cross check and quality assessment were conducted by two reviewers independently, and meta-analysis was performed with RevMan 5.0 software. Results A total of 13 studies involving 1 496 participants were included. The results of meta-analyses showed that: compared with the nitrate esters group, the tongxinluo capsule group had a better curative effect on the coronary heart disease than isosorbide dinitrate (RR=0.50, 95%CI 0.36 to 0.70) and isosorbide mononitrate (RR=0.19, 95%CI 0.12 to 0.30); there was significant difference in the total curative effect between the two groups (RR=0.34, 95%CI 0.26 to 0.44, Plt;0.000 01); the tongxinluo capsule was also better in improving the ECG than isosorbide dinitrate (RR=0.55, 95%CI 0.46 to 0.66) and isosorbide mononitrate (RR=0.58, 95%CI 0.48 to 0.70); there was significant difference in the total ECG improvement between the two groups (RR=0.56, 95%CI 0.49 to 0.64, Plt;0.000 01); the tongxinluo capsule group had a lower incidence rate of adverse reaction than the nitrate esters group with a significant difference (RR=0.33, 95%CI 0.20 to 0.53, Plt;0.000 01). Conclusion The present evidence indicates that tongxinluo capsule is not inferior to isosorbide dinitrate or isosorbide mononitrate in improving the curative effect and ECG, and it has fewer adverse reactions. More well-designed and large scale multi-centered RCTs are required with longer follow-up time to confirm this conclusion.
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.
ObjectiveTo discuss the characteristics of coronary artery disease in patients with type 2 diabetes using coronary angiography of Dual Source CT. MethodsWe collected the clinical data of patients who underwent coronary angiography of Dual Source CT between December 2010 and November 2012 in Sichuan Provincial People's Hospital and Sichuan Orthopedic Hospital. A total of 302 patients (74 with type 2 diabetes, and 228 with no diabetes) were examined with CT coronary angiography. All images were comprehensively assessed. Types of plaques and luminal narrowing were evaluated. ResultsPatients with type 2 diabetes had more plaques (P<0.05), especially mixed plaques and non-calcified plaques, than non-diabetic patients (P<0.05). The proportions of calcified plaque, mixed plaques, non-calcified plaque in patients with type 2 diabetes were 29.1%, 41.1%, 29.8%, respectively. The proportions of calcified plaque, mixed plaques, non-calcified plaque in patients with nondiabetic patients were 39.7%, 36.0%, 24.3%, respectively. The difference of the composition between diabetes and nondiabetic was significant (P<0.05). There were more mild, moderate and severe narrowing in type 2 diabetic patients than those in non-diabetic patients (P<0.05). ConclusionCoronary angiography of CT depicts a high plaque burden in patients with type 2 diabetes mellitus (mixed plaque is the most common type), which may cause stenosis easily.
