ABSTRACT
Objectives: In this article, we present our initial clinical experience with staged minimally invasive direct coronary bypass (MIDCAB), percutaneous coronary intervention (PCI), and transcatheter aortic valve implantation (TAVI) in high?risk octogenarians (Hybrid). Background: The use of percutaneous techniques for managing structural heart diseases, especially in elderly high?risk patients, has revolutionized the treatment of structural heart diseases. These procedures are present predominantly being offered as isolated interventions. The feasibility, clinical benefit, and outcomes of combining these techniques with MIDCAB have not been sufficiently explored and have subsequently been underreported in the contemporary literature. Methods: Four consecutive octogenarians with severe aortic stenosis (AS) and complex coronary artery disease (CAD) that were at high risk for conventional surgery with extracorporeal circulation (ECC) were discussed in our Multidisciplinary Heart Team(MDH). Our MDH consisted of an interventional cardiologist, cardiac surgeon, and cardiac anesthesiologist. A hybrid approach with the alternative strategy comprising of MIDCAB, PCI, and TAVI in a staged fashion was agreed on. All 4 patients had both PCI/stenting and MIDCAB prior to deployment of the TAVI?prosthesis. Results: From January 2019 to December 2020, 4 consecutive patients aged between 83 and 85 (3male/1 female) years were scheduled for MIDCAB/ PCI followed by percutaneous treatment of severe symptomatic AS. Intraoperatively, one patient was converted to full sternotomy, and surgery was performed by off?pump coronary artery bypass grafting. The overall procedural success rate was 100% in all 4 patients with resolution of their initial presenting cardiopulmonary symptoms. There were no severe complications associated with all hybrid procedures. There was no 30?day mortality in all patients. All patients were discharged home with a median hospital stay ranging between 9 and 25days. All patients have since then been followed?up regularly. There was one noncardiac?related mortality at 6?months postsurgery. All other patients were well at 1?year follow?up with improved NewYork Heart Association Class II. Conclusions: In a selected group of elderly, high prohibitive risk patients with CAD and severe symptomatic AS, a staged approach with MIDCAB and PCI followed by TAVI can be safely performed with excellent outcomes. We advocate a MDH?based preliminary evaluation of this patient cohort in selecting suitable patients and appropriate timing of each stage of the hybrid procedure.
ABSTRACT
Background: Previous studies compared optical coherence tomography (OCT) guided percutaneous coronary intervention (PCI) and angiography-guided was still limited. Therefore, we performed comprehensive meta-analyses to investigate the clinical outcomes of OCT-guided compared with angiography-guided PCI to provide a higher level of evidence. Methods: A systematic search from electronic databases such as Pubmed, EMBASE, SpringerLink, and Cochrane Library was conducted to obtain original articles comparing OCT and angiography. Major adverse cardiac events (MACE), cardiovascular death, myocardial infarction (MI), stent thrombosis, target vessel revascularization, stenosis area, PCI procedure time, contrast volume, and procedural side effects were the measured outcomes. The primary end-points were MACE and cardiovascular death. Results: Total 11 studies included 5814 patients were analyzed, with 3431 using OCT-guided and 2383 using angiography-guided. Pooled estimates of outcomes, presented as odds ratios (OR) [95% confidence intervals], were generated with random-effect models. Regarding clinical outcomes, OCT-guided PCI showed significantly lower rate of MACE (odds ratio [OR] 0.52, 95% confidence interval [CI] 0.38 to 0.72, p < 0.001), cardiovascular death (OR 0.47, 95% CI 0.33 to 0.67, p < 0.001), and higher contrast volume (OR 1.6, 95% CI 0.81 to 2.39, p < 0.001). OCT-guided has longer PCI procedure time (OR 2.42, 95% CI 1.33 to 4.42, p ¼ 0.004). OCT-guided has no significant difference in lower risk of periprocedural MI (OR 0.59, 95% CI 0.35 to 1.00, p ¼ 0.05), stent thrombosis (OR 0.69, 95% CI 0.2 to 2.43, p ¼ 0.56), target vessel repeat revascularization (OR 0.74, 95% CI 0.47 to 1.14, p ¼ 0.17), stenosis area (OR -0.63, 95% CI -1.5 to 0.25, p ¼ 0.56), and adverse events related to procedures (OR 1.33, 95% CI 0.8 to 2.19, p ¼ 0.27). Conclusion: Our meta-analysis demonstrated that OCT-guided PCI is significantly associated with lower MACE, cardiovascular death, and higher contrast volume. It is also associated with a longer duration of PCI. However, it is not associated with MI, stent thrombosis, target vessel revascularization, stenosis area, and adverse events related to procedures.
ABSTRACT
Background: Anaemia is prevalent among cases with acute coronary syndrome (ACS) and has been linked to poor clinical prognosis. Guidelines for cases with ST-segment elevation myocardial infarction (STEMI) recommend timely primary percutaneous coronary intervention (pPCI) as the preferred reperfusion strategy. If timely pPCI cannot be performed, a pharmacoinvasive strategy (PI) is recommended within 12 hours of symptom onset. The aim of this work was to study and assess the impact of hemoglobin level as a predictor of MACE and short-term outcomes in cases treated with Primary PCI vs pharmacoinvasive strategy. Methods: This prospective case-control observational study was conducted on 100 cases that were divided into 2 groups. Group I consisted of 50 anaemic cases & group II consisted of 50 cases that were not anaemic. Both groups were subdivided into A subgroups that underwent revascularization by pPCI and B subgroups that underwent revascularization by pharmacoinvasive strategy. Results: There was no significant difference in LVEF, infarct site and final TIMI flow, the anaemic groups showed statistically significant more total MACE than non-anaemic groups whether revascularized by pPCI or pharmacoinvasive strategy. As expected, anaemic cases tended to have higher bleeding complications especially those undergoing pharmacoinvasive strategy. The anaemic cases also were less likely to be discharged on RAAS and beta blockers. Conclusions: Anaemic cases whether revascularized with pPCI or pharmacoinvasive strategy tend to have higher incidence of MACE and major bleeding with no significant difference in mortality. There was no significant difference between LVEF between the study groups.
ABSTRACT
【Objective】 Coronary no-reflow during percutaneous conranary intervention (PCI) often results in the failure of ischemic myocardial reperfusion and major adverse cardiovascular events (MACE). The present study sought to evaluate whether the GRACE risk score can predict coronary no-reflow in STEMI patients undergoing PCI. 【Methods】 We consecutively recruited 1 118 patients with STEMI who were admitted to Gansu Provincial People’s Hospital and The First Affiliated Hospital of Xi’an Jiaotong University from January 2009 to December 2011. Main demographic data, cardiovascular risk factors, blood lipid and other biochemical indicators were recorded. Coronary angiography was performed by a radial artery approach using the standard Judkins technique. Coronary no-reflow was evaluated by at least two independent experienced cardiologists. The GRACE risk score was calculated with a computer program. All the cases were followed up by medical records, face-to-face interviews or telephone calls. Finally, we analyzed the predictive value of the GRACE risk score for coronary non-reflow and MACE in STEMI patients undergoing PCI. 【Results】 During a median period of 36 months, 58 of the 1 118 patients (5.2%) were lost to follow-up. Of the remaining 1 060 patients, 118 (11.1%) had no-reflow and 147 (13.9%) had MACE. The GRACE score was higher in patients with no-reflow than those without no-reflow. Multivariate logistic regression established that the GRACE score was an independent predictor for coronary no-reflow (OR=1.034; P=0.002). And multivariate Cox analysis showed the GRACE score was an independent predictor of MACE. The area under the ROC curve for coronary no-reflow and MACE was 0.719 and 0.697, respectively. Kaplan-Meier analysis showed that the probability of rehospitalization for heart failure, reinfarction, all-cause death and cumulative cardiovascular events increased with the increase of the GRACE risk score. 【Conclusion】 The GRACE risk score is a readily available predictive scoring system for coronary no-reflow and MACE in STEMI patients.
ABSTRACT
Background: Ischemic heart disease is considered the most common cause of death, worldwide. It accounts for 1.8 million deaths annually in Europe alone. According to the center for disease control (CDC) it’s the most common cause of deaths in Egypt accounting for more than one fifth of the total death count per year (21%), followed by stroke, then cancer. Aim: This work aimed to study and assess the efficacy of a pharmacoinvasive strategy compared with a primary PCI strategy on the left ventricle function in treatment of patient with myocardial infarction. Methods: Our study was prospective non randomized which compares between two groups, both of which had first time acute STEMI admitted to our Tanta University Hospital within the accepted time, which are (group 1) patients who had primary PCI for the infract related artery as a reperfusion therapy and (group 2) patients who had thrombolytic followed by coronary angiography with a window to PCI (pharmacoinvasive technique). Coronary angiography was performed either immediately in case of failed thrombolytic therapy or within 3-24 hrs. Following thrombolytic in case of successful thrombolytic. Both groups presented to the hospital within the accepted time window for reperfusion therapy either (thrombolytic or primary PCI), within 12 hrs. Results: The study compared between the two groups in the acute stage during hospitalization of the patients and after discharge according to Clinical outcomes: (mortality, major adverse cardiac events (MACE) as heart failure symptoms, re-infarction and Cardiac death),angiographic findings (base line TIMI flow score and final TIMI score, single or multi-vessel disease), angiographic complications as dissection and no-reflow, occurrence of contrast induced nephropathy and cerebrovascular events and LV systolic function assessment by echocardiography. Conclusion: In this study, we highlighted the importance of total ischemic time and importance of patient and system related delays in influencing outcomes of STEMI.
ABSTRACT
Background: Left ventricular (LV) dysfunction is the single most accurate predictor of death and one of the most common and lethal consequences after ST segment elevation myocardial infarction (STEMI) that has been substantially decreased by primary percutaneous coronary intervention (PCI). This research investigated the impact of duration of ischemia on the severity and improvement of wall motion abnormalities after revascularization and 40-day follow-up. Methods: This study was performed on 60 STEMI patients, treated with 1ry PCI and distributed in two groups; group1: 37 patients presented early before 12h and group II: 23 patients presented late after 12h. Echocardiogram (ECHO) was done for ejection fraction (EF) and resting segmental wall motion abnormalities (RSWMA) detection after revascularization within 24 h of hospitalization and follow up after 40 days. Results: MI complication showed insignificant difference between both groups. Wall motion score index (WMSI) values in group I were significantly decreased relative to group II during the follow-up period (p=0.001). Major improvement in LV ejection fraction from hospital admission to follow-up (p=0.001) in group I from the beginning of chest pain compared to group II. Correlation between time to wire crossing and WMSI showed significant positive correlation after 40 days in group I (p=0.016) with significant negative correlation with EF after 40 days in group I (p=0.018). Conclusions: Ischemic patients with ? 12 hours symptoms showed a significant degree of recovery from RWMA on follow up after 40 days.
ABSTRACT
Background: ST-segment elevation myocardial infarction (STEMI) is the most dramatic manifestation of coronary artery disease, acute STEMI is a clinical syndrome defined by characteristic symptoms of myocardial ischemia in association with persistent electrocardiographic ST elevation and subsequent release of biomarkers of myocardial necrosis. Reperfusion with thrombolysis or PCI (percutaneous coronary intervention) is the current standard of care for STEMI. Aims and Objectives: The aim of the study was to compare the effectiveness of fibrinolytic therapy and primary PCI which are the available reperfusion strategies for STEMI. Materials and Methods: This prospective and observational study was conducted at a tertiary care hospital in Bangalore. Patients presenting with STEMI to emergency department were treated with either fibrinolysis or PCI as per protocol. Patients in each arm were followed up to know the differences in outcome at discharge and 30-day follow-up. Results: Patients admitted with STEMI had overall in hospital mortality of 17 (7.1%) patients, of which 9 (7.6%) patients were from fibrinolysis group and 8 (6.6%) patients from PCI group with no statistically significant difference (P = 0.760). There was significant incidence (P = 0.001) of reinfarct in fibrinolysis group (9.3%) when compared to PCI group (0%). Conclusion: There was no statistically significant mortality difference at discharge and at 30 day between fibrinolysis and primary PCI in patients with STEMI in our study, this may be attributed to use of rescue PCI in failed fibrinolysis patients and early tricuspid valve repair in many patients after fibrinolysis.
ABSTRACT
Objectives: This prospective, randomized study assessed short-term outcomes and safety of ultra-low contrast percutaneous coronary intervention(ULC-PCI) vs conventional PCI in high risk for contrast induced acute kidney injury(CI-AKI) patients presenting with acute coronary syndrome(ACS). Background: Patients at an increased risk of developing CI-AKI can be identified prior to PCI based on their pre-procedural risk scores. ULC-PCI is a novel contrast conservation strategy in such high risk patients for prevention of CI-AKI. Methods: 82 patients undergoing PCI for ACS were enrolled having estimated glomerular filtration rate(eGFR) < 60 ml/min/1.73 m2 and moderate to very high pre-procedural risk of developing CI-AKI as calculated by Maioli risk calculator. They were randomized into two groups of 41 patients each of ULCPCI (contrast volume patient's eGFR) and conventional PCI (contrast volume 3xpatient's eGFR). Primary end point was development of CI-AKI. Results: Baseline clinical and angiographic characteristics were similar between groups. Primary outcome of CI-AKI occurred more in patients of the conventional PCI group [7 (17.1%)] than in the ULC PCI group [(0 patients), p ¼ 0.012]. Contrast volume (41.02 (±9.8) ml vs 112.54 (±25.18) ml; P < 0.0001) was markedly lower in the ULC-PCI group. No significant difference in secondary safety outcomes between two study arms at 30 days. IVUS was used in 17% patients in ULC PCI. Conclusion: ULC-PCI in patients with increased risk of developing CI-AKI is feasible, appears safe, and has the potential to decrease the incidence of CI-AKI specially in resource limited setting such as ours where coronary imaging by IVUS is not possible in every patient.
ABSTRACT
Objective: In patients with acute coronary artery disease, the TIMI risk index (TRI), the thrombolysis in myocardial infarction (TIMI) risk score, and the global registry of acute coronary events (GRACE) risk score (GRS) have all been documented. The aim of this study was to determine the relationship between no-reflow (NRF) and admission TRI, major cardiac events (MACE), and in-hospital mortality in patients undergoing primary percutaneous coronary intervention (P-PCI). Methods: Between March and December 2019, 100 consecutive patients diagnosed with STEMI and treated with PPCI at Tanta Main University Hospital in Tanta, Egypt, were included in the research population. Each patient consented following a thorough history taking, evaluation of coronary risk factors, clinical examination, and electrocardiogram analysis. Additionally, all instances were classified using the Killip method. The GRS, TRS, and TRI values were examined. Results: The GRS, TRS, and TRI scores were significantly associated with increased NRF, MACE, and hospital mortality in STEMI patients treated with P-PCI, suggesting that TRI is a straightforward indicator with fewer parameters that accurately reflects P-PCI success. Conclusion: TRI has been demonstrated to enhance the risk of in-hospital mortality and MACE. TRI uses straightforward and cost-effective ways to test patients who have experienced a STEMI. Additionally, a high TRI may assist in identifying high-risk individuals and developing suitable treatment solutions.
ABSTRACT
Objective: The elevation of troponin-T (Trop-T) or creatinine kinase myocardial isoform (CKMB) is very common during the percutaneous coronary intervention (PCI). A study was attempted to determine the correlation between elevated Trop-T or CKMB and the parameters of PCI by using multivariate analysis, especially principal component analysis (PCA). Materials and Methods: A prospective observational study was carried out among 100 patients who underwent PCI for stable coronary artery disease in which 31 and 37 patients were found to have elevated Trop-T and CKMB (>3 times) following PCI. The correlation was studied between Trop-T or CKMB (dependent variable) and different parameters, viz., total stent length (mm), fluoroscopy time (min), lesion strength, left ventricular (LV) function, procedural complications, type of lesions, vessels treated with drug eluting stent (DES), and major adverse cardiac events (MACE) as independent variables. Results: For Trop-T, the principal component (PC)-1 and PC-2 obtained 63.49% and 30.88% of the original variation. For PC-1 and PC-2, maximum positive loading was recorded for stent length followed by fluoroscopy time and for LV but negative loading for the type of lesion and type of stent (DES vs bare metal stent [BMS]). For CKMB, the PC-1 and PC-2 obtained 61.22% and 32.08% of the original variation. For PC-1 and PC-2, maximum positive loading was recorded for stent length and fluoroscopy time followed by vessel treated but negative loading for the type of stent and MACE, and maximum positive loading recorded for LV function but negative loading for the type of lesion. Conclusion: This study indicates which factors are most important in preventing periprocedural myocardial injury during PCI and may be a suitable tool to prevent myocardial injury and for subsequent less MACE and better patient outcomes.
ABSTRACT
Ultra-low contrast percutaneous coronary intervention (ULCPCI) can be performed electively in advanced chronic kidney disease. Engage guide catheter and advance guidewire into the coronary artery without using contrast. IVUS-guided PCI can reduce the contrast load. Perform co-registration of distal and proximal radio-opaque marker bands of intravascular ultrasound (IVUS) catheter. Deploy the stent at the target lesion under fluoroscopic guidance of these co-registered position of the IVUS-marking images. Complete the ULCPCI procedure with a final angiography using minimal contrast. Newer contrast sparing techniques and intravascular imaging technologies provide opportunities to perform ULCPCI efficiently with good results and the least complications
ABSTRACT
Objective: RADPAD is a lead-free sterile drape that reduces scattered radiation during fluoroscopic procedures. We aimed to study the effect of using RADPAD on primary operator (PO) and secondary operator (SO) during coronary angiography (CAG) as well as percutaneous coronary intervention (PCI). Methods: 137 patients undergoing elective CAG and PCIwere randomized in a 1:1 pattern with or without the RADPAD. The ratio of PO received dose in mrem to total Air Kerma (AK) in mGy, Dose Area Product (DAP) in mGycm2 and Cine Adjusted Screening Time (CAST) in minute, at the end of the procedure with or without RADPAD were measured and designated as dose relative to AK, DAP and CAST. The exposure ratios were compared for both cohorts. Results: There was no significant difference in CAST, DAP and AK between the two patient cohorts. PO radiation dose relative to CAST was 0.15 ± 0.18 mrem/min for RADPAD cohort and 0.43 ± 0.31 mrem/min for No RADPAD cohort (p < 0.00001). PO dose relative to DAP was 0.00042 ± 0.00049 mrem/mGycm2 for RADPAD cohort and 0.0011 ± 0.0013 mrem/mGycm2 for No RADPAD cohort (p ¼ 0.000014). PO dose relative to AK was 0.0030 ± 0.0037 mrem/mGy for RADPAD cohort and 0.0071 ± 0.0049 mrem/mGy for No RADPAD cohort (p < 0.00001). All PO doses relative to CAST, DAP and AK were significantly reduced in the RADPAD cohort compared to the No RADPAD cohort. Similar findings were observed for the SO also. Conclusion: RADPAD significantly reduces radiation exposure to both PO and SO during CAG and PCI. © 2022 Published by Elsevier, a division of RELX India, Pvt.

ABSTRACT
Background: Acute myocardial infarction (AMI) is often characterised pathologically as the death of cardiomyocytes as a consequence of persistent ischaemia result in an acute imbalance among oxygen supply and demand. Coronary artery disease (CAD) is the leading cause of death worldwide. AMI mainly affects patients older than 40 years of age, however, young can suffer MI. In the developing countries, CAD is becoming an epidemic, where it occurs in younger persons at greater rates. Clinical features and prognosis of young patients tend to vary from those of older individuals. the outcomes of a MI may be especially severe at a young age because of its larger potential influence on the patient's psyche, capacity to work, and socioeconomic burden. AMI is less prevalent in young people than in older persons, since only 2 to 6 % of the younger population suffers from the condition. Primary PCI is the optimal therapy for STEMI if it can be done promptly, preferably within 90-120 minutes of provider contact. Methods: The present research performed on 60 subjects who had AMI and treated with primary PCI. The cases were allocated into 2 groups, group 1 involved young subjects aged 40 years old or less (30 patients) and group 2 involved older patients aged more than 40 years (30 patients). All patients underwent complete history taking, cardiological clinical examination, investigations, coronary angiography and PCI. Results: Concerning age there was statistically significant difference among two groups while there was no significant difference regarding to sex. regarding risk factors there was significant difference among both groups regarding to hypertension, DM, previous MI, cerebrovascular disease and drug abuse. Regarding to laboratory investigation, there was no significant difference regarding CK, CKMB, creatinine and random blood sugar. There was no significant difference regarding to culprit artery and TIMI flow after PCI while there was statistically significant difference regarding number of vessels involved. Regarding to outcome there was no significant variation among the two groups regarding to acute HF, cardiogenic shock, re-infarction, and death. As regarding to bleeding, it was significant higher in group II. Conclusions: Prevalence of Acute ST Elevation Myocardial Infarction “STEMI” in young people is increasing due to sedentary and stressful lifestyle and bad habits as smoking and addiction. The most widespread and important risk factors in these patients are smoking, addiction, mental stress and hyperlipidemia with less prevalence of hypertension and diabetes mellitus. Young patients present most commonly with anterior then inferior STEMI.
ABSTRACT
Background: through coronary artery bypass graft (CABG) or through utilization of percutaneous coronary intervention (PCI) with stenting, coronary revascularization can be achieved. Diabetics represents a particularly challenging group for both treatments. This work aimed to estimate clinical outcome in diabetic individuals with multiple vessels disease (MVD) who had either PCI or CABG over 30 days. Methods: This prospective research was conducted on 200 diabetic individuals with MVD established as severe stenosis. Into 2 equal groups, individuals were divided: Group (A) [underwent CABG], and group (B) [performed Drug Eluting Stents (DES) PCI]. All individuals underwent full history taking, resting twelve-leads electrocardiogram, complete clinical examination, transthoracic echocardiography, coronary angiographic, SYNTAX score and Euro score. Results: In CABG group, age, statin, ACE-I/ARB, ?- -blocker and dual antiplatelet therapy was significantly higher than PCI group. PCI group had significantly higher PCI, MI and repeated revascularization than the group of CABG. In PCI group, stroke and MI, death, myocardial infarction (MI), were significantly higher than in group of CABGS. Conclusions: DES have developed for the coronary artery disease (CAD) treatment and are increasingly being utilized for complex CAD treatment, such as multivessel or left main CAD. PCI is preferred over CABG in high surgical risk individuals due to the shorter hospital stay, faster time of recovery, and potentially decreased stroke rate
ABSTRACT
Aims: This study aims to assess differences in severity of short-term (<1 year) and long-term (_x005F_x0001_1 year) adverse CV outcomes after PCI in insulin-treated vs. non-insulin-treated diabetes mellitus (DM) patients. Methods: A systematic search on Pubmed and Embase led to the incorporation of 29 studies that compared post-percutaneous coronary interventional outcomes in insulin-treated and non-insulintreated diabetes mellitus. Diabetes mellitus (type 2) was defined as fasting blood glucose (FBG) level of >7.0 mmol/L or with an oral glucose tolerance test (OGTT) level of >11.1 mmol/L at least on two separate occasions. Adverse CV outcomes were assessed in insulin-treated and non-insulin-treated DM after the PCI procedure considered for the analyses were mortality, MACE, TLR, TVR, MI, stent thrombosis, target lesion failure (TLF), and need for-post PCI CABG. Data were pooled and analyzed using Review Manager 5.3, and risk ratios (RR) with respective 95% confidence intervals (CI) were calculated.The statistical analyses were carried out by Review Manager v.5.3, and the data were pooled using a random-effects model. Risk ratios (RRs) with 95% confidence intervals (CI) were reported along with forest plots. The chi-square test was performed to assess for differences between the subgroups. Heterogeneity across studies was evaluated using Higgins I2 statistics. Visual inspection of the funnel plot and Begg's regression test were used to assess publication bias. Results: A total of 40,527 patients (11742 in the Insulin-treated diabetes mellitus group and 28785 in the non-insulin-treated DM group) who underwent PCI were included. The pooled analysis of short-term follow up outcomes preceding PCI demonstrated a significantly higher risk of mortality (RR ¼ 1.75 [1.24,2.47]; p ¼ 0.002), MI (RR ¼ 1.81[1.14,2.87]; p ¼ 0.01], stent thrombosis (RR ¼ 1.63[1.13, 2.35]; p ¼ 0.009) and target lesion revascularization (TLR) (RR ¼ 1.29[1.02,1.63]; p ¼ 0.03) in insulin-treated DM patients. Similarly, analysis of long-term follow-up studies depicted a significantly higher risk mortality (RR ¼ 1.55 [1.22, 1.97]; p ¼ 0.0003), MI (RR ¼ 1.63 [1.35, 1.97]; p¼<0.00001), MACE (R ¼ 1.47 [1.31, 1.65]; p¼<0.00001), stent thrombosis (RR ¼ 1.54 [1.19,1.99]; p ¼ 0.001), TLR (RR ¼ 1.40 [1.18, 1.66]; p ¼ 0.0001), target vessel revascularization (TVR) (RR ¼ 1.35 [1.11, 1.64]; p ¼ 0.003) in insulin-treated DM group after PCI versus non-insulin-treated DM patients. Conclusion: Despite a tremendous technical success rate of multi-vessel stenting, people living with diabetes who were being treated with insulin had higher long-term, and short-term mortality rates, MI, TLR, TVR, and stroke compared to people living with diabetes who were being treated with means other than insulin and are more prone to detrimental cardiovascular outcomes.

ABSTRACT
Objective To summarize the incidence of cardiac allograft vasculopathy (CAV) after heart transplantation and the effect on the long-term survival of recipients. Methods Clinical data of 1 006 heart transplant recipients were retrospectively analyzed. Of 48 CAV patients, 4 cases were not included in this analysis due to lack of imaging evidence. A total of 1 002 recipients were divided into the CAV group (n=44) and non-CAV group (n=958) according to the incidence of CAV. The incidence of CAV was summarized. Clinical data of all patients were statistically compared between two groups. Imaging diagnosis, coronary artery disease, drug treatment and complications, postoperative survival and causes of death of CAV patients were analyzed. Results Among 1 006 heart transplant recipients, 48 cases (4.77%) developed CAV. Compared with the non-CAV group, the proportion of preoperative smoking history, preoperative hypertension history, coronary artery disease and perioperative infection was significantly higher in the CAV group (all P < 0.05). Among 44 patients diagnosed with CAV by imaging examination, 24 cases were diagnosed with CAV by coronary CT angiography (CTA), 4 cases by coronary angiography (CAG), and 16 cases by coronary CTA combined with CAG. Among 44 patients, the proportion of grade Ⅰ CAV was 45% (20/44), 30% (13/44) for grade Ⅱ CAV and 25% (11/44) for grade Ⅲ CAV, respectively. All patients received long-term use of statins after operation, and 20 patients were given with antiplatelet drugs. Among 44 CAV patients, 11 patients underwent percutaneous coronary intervention, 6 cases received repeated heart transplantation, and 8 patients died. Kaplan-Meier survival analysis demonstrated that there was no significant difference in the long-term survival rate between the CAV and non-CAV groups (P > 0.05), whereas the survival rate of patients tended to decline after the diagnosis of CAV (at postoperative 6-7 years). The long-term survival rates of patients with grade Ⅰ, grade Ⅱ and grade Ⅲ CAV showed no significant difference (P > 0.05). Even for patients with grade Ⅰ CAV, the long-term survival rate tended to decline. Conclusions CAV is a common and intractable complication following heart transplantation, and the long-term survival rate of patients after the diagnosis of CAV tended to decline. Deepening understanding of CAV, prompt prevention, diagnosis and treatment should be delivered to improve the long-term survival rate of patients after heart transplantation.

Objectives@#This study aimed to determine the correlation between admitting hyperglycemia and hospital outcome, on the length of hospital stay and mortality on patients who underwent PCI.@*Methodology@#A single center, retrospective observational study involving patients who underwent percutaneous coronary intervention (PCI). They were divided in four (4) groups according to presence of admission hyperglycemia (capillary blood glucose >140mg/dl) and presence of diabetes: Group 1 (patients with diabetes with admission hyperglycemia), Group 2 (patients without diabetes with admission hyperglycemia), Group 3 (patients with diabetes without admission hyperglycemia), and Group 4 (patients without diabetes without admission hyperglycemia). Length of hospital stay and mortality outcome were compared between four groups and in-hospital mortality related risk factors were analyzed by binary logistic regression analysis.@*Results@#133 patients were included in the analysis, of which 50% have admission hyperglycemia. The length of hospital stay was significantly longer in patients with admission hyperglycemia (12 vs 9 vs 7 vs 7 days, p= 0.006). The mortality rate between 4 groups were non-significant (14% vs 10% vs 9% vs 11%, p=0.272). Multiple logistic regression analysis showed the following were associated with increased mortality in patients who underwent PCI: age (odds ratio [OR] 1.1265, 95%CI 1.0497 – 1.2090, p=0.001), capillary blood glucose on admission (OR 1.0077, 95% CI 1.0015 – 1.0140, p= 0.015), presence of ST elevation on ECG (OR 16.5671, 95% CI 3.4161 – 80.344, p=<0.001).@*Conclusion@#An elevated admission capillary blood glucose, regardless of presence or absence of diabetes, was associated with longer length of hospital stay; however, it was not predictive of in-hospital mortality. Interestingly, patients with admitting hyperglycemia had earlier mortality.

Introduction@#Left main coronary artery (LMCA) is a large vessel which supplies the majority of left ventricle and critical lesion at the bifurcation of LMCA can lead to life threatening condition. Therefore, percutaneous coronary intervention (PCI) on LMCA bifurcational stenosis is considered as a complex high risk indicated patient and procedure (CHIP).@*Goal@#In this study, we investigated the impact of urgent and elective PCI on outcomes of patients with LMCA bifurcational stenosis. @*Materials and Methods@#Patients who underwent for urgent PCI due to acute myocardial infarction (AMI) or elective PCI due to stable coronary artery disease (CAD) for their LMCA bifurcational stenosis. Any lesion with >50% stenosis on coronary angiography was considered as a critical stenosis. LMCA bifurcational stenosis was evaluated by Medina classification. Difference between urgent and elective PCI group were compared by independent sample t-test and chi-square test. Association between treatment strategy (urgent or elective PCI) and prognosis were evaluated by Cox proportional hazard regression, and survival rate was evaluated by Kaplan-Meier methods. Ethical approval was taken from the ethical committee of the Health Science University of Medical Sciences (№30/1А) in June 12, 2012. @*Results@#A total of 82 patients with LMCA bifurcational stenosis were included (mean age 62±11, male 76.8%) and 14 of them underwent urgent PCI due to AMI and 68 of had elective PCI due to stable CAD. Patients who underwent urgent PCI had significantly higher 30-day mortality (1.5% vs. 21.4%, p<0.05) and all-cause mortality (7.4% vs. 35.7%, p<0.003) compared to the elective PCI group. Urgent PCI for LMCA bifurcational stenosis due to AMI was associated with increased risk of death (HR=3.63, 95% CI 1.02-12.9, p<0.05). Kaplan-Meier estimation showed that patients in the urgent PCI group had significantly lower survival compared to the elective PCI group.@*Conclusion@#Unanticipated urgent PCI for patients with LMCA bifurcational stenosis due to AMI is associated with higher risk of short and long-term mortality. Patients who underwent urgent PCI for LMCA bifurcational stenosis had significantly lower survival compared to elective PCI group.
