ABSTRACT

BACKGROUND: Progressive Familial Intrahepatic cholestasis type I (PFIC1) is a rare congenital hepatopathy causing cholestasis with progressive liver disease. Surgical interruption of the enterohepatic circulation, e.g., surgical biliary diversion (SBD) can slow down development of liver cirrhosis. Eventually, end stage liver disease necessitates liver transplantation (LT). PFIC1 patients might develop diarrhea, graft steatosis and inflammation after LT. SBD after LT was shown to be effective in the alleviation of liver steatosis and graft injury.

CASE REPORT: Three PFIC1 patients received LT at the ages of two, two and a half and five years. Shortly after LT diarrhea and graft steatosis was recognized, SBD to the terminal ileum was opted to prevent risk for ascending cholangitis. After SBD, inflammation and steatosis was found to be reduced to resolved, as seen by liver biochemistry and ultrasounds. Diarrhea was reported unchanged.

CONCLUSION: We present three PFIC1 cases for whom SBD to the terminal ileum successfully helped to resolve graft inflammation and steatosis.

ABSTRACT

BACKGROUND: Necrotising enterocolitis (NEC) is a significant cause of mortality and morbidity in neonates requiring cardiac surgery. Feeding practices vary significantly across institutions and remain controversial. We conducted a systematic review of the literature and a meta-analysis to identify associations between feeding practices and necrotising enterocolitis.

METHODS: This study was carried out in accordance with the PRISMA guidelines. A literature search was performed in November 2022 using the Cochrane Central Register, Embase, and Pubmed. Two investigators then independently retrieved eligible manuscripts considered suitable for inclusion. Data extracted included gestational age, birth weight, sex, nature of congenital heart lesion, type of operation performed, time on ventilator, ICU stay, hospital stay, post-operative feeding strategy, and complications. The methodological quality was assessed using the Downs and Black score for all randomised control trials and observational studies.

RESULTS: The initial search yielded 92 studies. After removing duplicates, there were 85 abstracts remaining. After excluding ineligible studies, 8 studies were included for the meta-analysis. There was no significant risk of NEC associated with pre-operative feeding [OR = 1.22 (95% CI 0.77,1.92)] or umbilical artery catheter placement [OR = 0.91 (95% CI 0.44, 1.89)] and neither outcome exhibited heterogeneity [I2 = 8% and 0%, respectively]. There was a significant association between HLHS and NEC [OR = 2.56 (95% CI 1.56, 4.19)] as well as prematurity and NEC [OR 3.34 (95% CI 1.94, 5.75)] and neither outcome exhibited heterogeneity [I2 = 0% and 0%, respectively].

CONCLUSIONS: There was no association between NEC and pre-operative feeding status in neonates awaiting cardiac surgery. Pre-operative feeding status was not associated with prolonged hospital stay or need for tube assisted feeding at discharge. HLHS and prematurity were associated with increased incidence of NEC.

ABSTRACT

Transthoracic echocardiography (TTE) is an essential tool for diagnosis and management of congenital heart disease. Pediatric echocardiography presents unique challenges including complex anatomy, variable patient cooperation and provider expertise. Diagnostic errors inevitably occur. We designed a collaborative and stepwise quality improvement (QI) process to address diagnostic errors within our laboratory. We retrospectively reviewed medical records to identify diagnostic TTE errors in 100 consecutive cardiac surgery patients ≤ 5 years old (July 2020-January 2021). We identified 18 diagnostic errors. Most errors had minor impact (14/18), and 13 were preventable or possibly preventable. We presented these results to our sonographers and faculty and requested input on preventing and managing diagnostic errors. Our root cause analysis based on their responses yielded 7 areas for improvement (imaging, reporting, systems, time, environment, people, QI processes). Our faculty and sonographers chose QI processes and imaging as initial areas for intervention. We defined our SMART goal as a 10% reduction in diagnostic errors. We implemented interventions focused on QI processes. On initial follow up in May 2022, we identified 7 errors in 70 patients (44% reduction in error rate). Utilizing a stepwise and team-based approach, we successfully developed QI initiatives in our echocardiography laboratory. This approach can serve as a model for a collaborative QI process in other institutions.

ABSTRACT

BACKGROUND: Duodenal obstruction (DO) is a congenital anomaly that is highly associated with other anomalies, such as cardiac anomalies and trisomy 21. However, an overview of additional anomalies and patient-specific risk factors for cardiac anomalies is lacking. Potential association with the vertebral, anorectal, cardiac, trachea-esophageal, renal and limb anomalies (VACTERL) spectrum remains unknown. Therefore, we aim to examine the incidence of associated anomalies, a VACTERL-spectrum association and patient-specific risk factors for cardiac anomalies in patients with DO.

METHODS: A retrospective cohort study was performed between 1996 and 2021. Outcomes were the presence of any additional anomalies. Risk factors for cardiac anomalies were analyzed using multivariate logistic regression.

RESULTS: Of 112 neonates with DO, 47% (N = 53/112) had one associated anomaly and 38% (N = 20/53) had multiple anomalies. Cardiac anomalies (N = 35/112) and trisomy 21 (N = 35/112) were present in 31%. In four patients, VACTERL-spectrum was discovered, all with cardiac anomalies. Trisomy 21 was found to be a risk factor for cardiac anomalies (OR:6.5; CI-95%2.6-16.1).

CONCLUSION: Associated anomalies were present in half of patients with DO, of which cardiac anomalies and trisomy 21 occurred most often, and the VACTERL-spectrum was present in four patients. Trisomy 21 was a significant risk factor for cardiac anomalies. Therefore, we recommend a preoperative echocardiogram in patients with DO. In case a cardiac anomaly is found without trisomy 21, VACTERL-screening should be performed.

ABSTRACT

Although the genetic origins underpinning congenital heart disease (CHD) have been extensively studied, genes, by themselves, do not entirely predict phenotypes, which result from the complex interplay between genes and the environment. Consequently, genes merely suggest the potential occurrence of a specific phenotype, but they cannot predict what will happen in reality. This task can be revealed by metabolomics, the most promising of the "omics sciences". Though metabolomics applied to CHD is still in its infant phase, it has already been applied to CHD prenatal diagnosis, as well as to predict outcomes after cardiac surgery. Particular metabolomic fingerprints have been identified for some of the specific CHD subtypes. The hallmarks of CHD-related pulmonary arterial hypertension have also been discovered. This review, which is presented in a narrative format, due to the heterogeneity of the selected papers, aims to provide the readers with a synopsis of the literature on metabolomics in the CHD setting.

ABSTRACT

BACKGROUND: In children with hypoplastic left heart syndrome (HLHS), volume overload (VO) is inevitable, and the right ventricle (RV) pumps blood into the systemic circulation. Understanding the molecular differences and their different responses to VO between the RV and left ventricle (LV) at the neonatal and highly plastic stages may improve the long-term management of children with HLHS.

METHODS AND RESULTS: A neonatal rat ventricular VO model was established by the creation of a fistula between the inferior vena cava and the abdominal aorta on postnatal day 1 (P1) and confirmed by echocardiographic and histopathological analyses. Transcriptomic analysis demonstrated that some of the major differences between a normal neonatal RV and LV were associated with the thyroid hormone and insulin signaling pathways. Under the influence of VO, the levels of insulin receptors and thyroid hormone receptors were significantly increased in the LV but decreased in the RV. The transcriptomic analysis also demonstrated that under the influence of VO, the top two common enriched pathways between the RV and LV were the insulin and thyroid hormone signaling pathways, whereas the RV-specific enriched pathways were primarily associated with lipid metabolism and arrhythmogenic right ventricular cardiomyopathy (ARVC); further, the LV-specific enriched pathways were primarily associated with nucleic acid metabolism and microRNAs in cancer.

CONCLUSIONS: Insulin and thyroid hormones may play critical roles in the differences between a neonatal RV and LV as well as their common responses to VO. Regarding the isolated responses to VO, the RV favors an ARVC change and the LV favors a reduction in microRNAs in cancer. The current study suggests that insulin, thyroid hormone, and cancer-associated microRNAs are potential therapeutic targets that should be explored by basic science studies to improve the function of the RV to match that of the LV.

ABSTRACT

This case report describes a patient with bioprosthetic mitral valve dehiscence that resulted in severe paravalvular regurgitation and cardiogenic shock. Due to prohibitive surgical risk, valve-in-valve transcatheter mitral valve replacement was attempted but did not reduce the severity of the prosthetic paravalvular leak (PVL) severity. Subsequent percutaneous PVL closure with a ventricular septal defect occluder successfully reduced the PVL severity and led to significant clinical improvement.

ABSTRACT

Insomnia is a modifiable cardiovascular risk factor. Previous studies suggested that attending a cardiac rehabilitation program may improve sleep quality in cardiac patients and pointed out the association between heart failure and poor sleep quality. The primary aim of this study was to evaluate sleep quality in patients attending a Multidisciplinary Cardiac Rehabilitation Program (MRCP), and to compare sleep quality between patients with and without heart failure. A prospective observational study was carried out on a consecutive sample of 240 patients attending an 8-week MRCP; 50 patients (20.8%) were included due to heart failure (NYHA stages I-III) and the rest of them after having undergone any revascularization procedure or valvular surgery. Before and after the completion of the MRCP, the quality of sleep was assessed by the Pittsburgh Sleep Quality Index (PSQI) score. Post-intervention global PSQI scores were statistically significantly lower than those of pre-intervention (p = 0.008), but only 60 patients (25%) registered a clinically significant improvement. When comparing patients with heart failure with those without, no differences in sleep quality were found. This suggests that only a small percentage of patients can achieve clinically significant improvements in sleep quality attending conventional MCRP. Suggestions for future research are given.

ABSTRACT

Extracorporeal membrane oxygenation (ECMO) may be a viable salvage therapy in selected patients with septic shock. As ECMO use increases, we studied left ventricular (LV) performance during sepsis with and without ECMO using a pressure-volume (PV) loop in a murine model and aimed to understand LV hemodynamics in septic shock with ECMO. The rats were divided into Group 1 (ECMO applied to healthy rats), Group 2 (ECMO for septic rats), Group 3 (Controls, n = 20) and Group 4 (Sepsis induction only, n = 20). The cardiac parameters include end-diastolic volume (EDV), end-systolic volume (ESV), end-diastolic pressure (EDP), and end-systolic pressure (ESP), ejection fraction (EF), end-systolic elastance (Ees), diastolic time constant (Tau) index, arterial elastance (Ea), pressure-volume area (PVA), stroke work (SW), and potential energy (PE). We compared the changes of parameters in all groups. A total of 74 rats were included in the analyses. After 2 h on ECMO, Group 2 was associated with significant increases in ESP, EDV, ESV, PVA, PE, and SW. The difference ratio of PE and PVA was significantly higher in Group 2 compared to Group 1 (P < 0.01). In conclusion, myocardial oxygen consumption was higher in septic shock with ECMO than in controls.

ABSTRACT

About 5% of patients with heart failure (HF) reach the end-stage of disease, becoming refractory to therapy. The clinical course of end-stage HF is characterized by repeated hospitalizations, severe symptoms, and poor quality of life. Peritoneal ultrafiltration (PUF), removing water and sodium (Na+), can benefit patients with end-stage HF. However, effects on fluid and electrolyte removal have not been fully characterized. In this pilot study in patients with chronic HF and moderate chronic renal failure, we evaluated the effects of water and sodium removal through PUF on ventricular remodeling, re-hospitalization, and quality of life. Patients with end-stage HF (NYHA class IV, ≥3 HF hospitalization/year despite optimal therapy), not eligible for heart transplantation underwent peritoneal catheter positioning and began a single-day exchange with icodextrin at night (n=6), or 1-2 daily exchanges with hypertonic solution (3.86%) for 2 hours with 1.5-2 L fill volume (n=3). At baseline, average ultrafiltration was 500±200 ml with icodextrin, and 700±100 ml with hypertonic solution. Peritoneal excretion of Na+ was greater with icodextrin (68±4 mEq/exchange) compared to hypertonic solution (45±19 mEq/exchange). After a median 12-month follow-up, rehospitalizations decreased, while NYHA class and quality of life (by Minnesota Living with HF questionnaire), improved. In end-stage HF patients, PUF reduced re-hospitalization and improved quality of life. It can be an additional treatment to control volume and sodium balance.

ABSTRACT

BACKGROUND: Despite numerous promising innovations, the chance of survival from sudden cardiac arrest has remained virtually unchanged for decades. Recently, technological advances have been made, user-friendly portable devices have been developed, and advanced invasive procedures have been described that could improve this unsatisfactory situation.

METHODS: A selective literature search in the core databases with a focus on randomized controlled trials and guidelines.

RESULTS: Technical aids, such as feedback systems or automated mechanical cardiopulmonary resuscitation (CPR) devices, can improve chest compression quality. The latter, as well as extracorporeal CPR, might serve as a bridge to treatment (with extracorporeal CPR even as a bridge to recovery). Sonography may be used to improve thoracic compressions on the one hand and to rule out potentially reversible causes of cardiac arrest on the other. Resuscitative endovascular balloon occlusion of the aorta might enhance myocardial and cerebral perfusion. Minithoracostomy, pericardiocentesis, or clamshell thoracotomy might resolve reversible causes of cardiac arrest.

CONCLUSIONS: It is crucial to identify those patients who may benefit from an advanced or invasive procedure and make the decision to implement the intervention in a timely manner. As with all infrequently performed procedures, sound education and regular training are paramount.

ABSTRACT

The strong interaction of blood with the foreign surface of membrane oxygenators during ECMO therapy leads to adhesion of immune cells on the oxygenator membranes, which can be visualized in the form of image sequences using confocal laser scanning microscopy. The segmentation and quantification of these image sequences is a demanding task, but it is essential to understanding the significance of adhering cells during extracorporeal circulation. The aim of this work was to develop and test a deep learning-supported image processing tool (Deetect), suitable for the analysis of confocal image sequences of cell deposits on oxygenator membranes at certain predilection sites. Deetect was tested using confocal image sequences of stained (DAPI) blood cells that adhered to specific predilection sites (junctional warps and hollow fibers) of a phosphorylcholine-coated polymethylpentene membrane oxygenator after patient support (>24 h). Deetect comprises various functions to overcome difficulties that occur during quantification (segmentation, elimination of artifacts). To evaluate Deetects performance, images were counted and segmented manually as a reference and compared with the analysis by a traditional segmentation approach in Fiji and the newly developed tool. Deetect outperformed conventional segmentation in clustered areas. In sections where cell boundaries were difficult to distinguish visually, previously defined post-processing steps of Deetect were applied, resulting in a more objective approach for the resolution of these areas.

ABSTRACT

BACKGROUND: To validate the utility and performance of the gastro-laryngeal tube (GLT) in terms of cardiologist and patient satisfaction levels, incidence of and attempts at successful transesophageal echocardiography (TEE) probe placement, perioperative and postoperative hemodynamics, and adverse events related to the TEE procedure.

METHODS: In this randomized prospective clinical study, forty-four patients undergoing TEE and aged 20 to 80 years old scheduled for TEE were randomly allocated to two study groups: Group SA (sedation and analgesia) and Group GLT. Cardiologist and patient satisfaction levels, TEE probe placement performance, hemodynamics, adverse events related to the TEE procedure, demographic characteristics, and TEE procedure data were recorded.

RESULTS: The cardiologist satisfaction level was significantly higher in Group GLT (P = .011). The TEE probe was successfully placed at the first attempt in all the patients in Group GLT and at the first attempt in 11 patients, at the second attempt in 8 patients, and at the third attempt in 3 patients in Group SA. The TEE probe placement success was significantly higher in Group GLT (P < .001), and TEE probe placement was significantly easier in Group GLT (P < .001). There were no significant differences in patient satisfaction, heart rate, mean arterial pressure, oxygen saturation, adverse events related to the TEE procedure between the groups.

CONCLUSION: The present study revealed that GLT use elicited a higher cardiologist satisfaction level and resulted in more successful and easier TEE probe placement. We thus conclude that the use of the recently developed GLT may ensure airway management safety and a comfortable TEE experience.

ABSTRACT

There is an ongoing debate whether coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) provide better results for the treatment of coronary artery disease (CAD). We aimed to evaluate the impact of CABG or PCI on long-term survival based on local reports from different regions in the world. We systematically searched MEDLINE selecting studies that compared outcomes for CABG or PCI as a treatment for CAD in the last 10 years. Reports without all-cause mortality, multi-national cohorts, hybrid revascularization populations were excluded. Qualifying studies were statistically compared, and their geographic location visualized on a world map. From 5126 studies, one randomized and twenty-two observational studies (19 risk-adjusted) met the inclusion criteria. The mean follow-up was 4.7 ± 7 years and 18 different countries were included. In 17 studies, CABG was associated with better survival during follow-up, six studies showed no significant difference, and no study favored PCI. Periprocedural mortality was not different in seven, lower with PCI in one, lower with CABG in three and not reported in 12 studies. In regional registry-type comparisons, CABG is associated with better long-term survival compared to PCI in most regions of the world without evidence for higher periprocedural mortality.

ABSTRACT

BACKGROUND: Systematic prescription of beta-blockers after myocardial infarction remains an open question in the era of revascularization, especially for patients with uncomplicated myocardial infarction.

OBJECTIVE: To evaluate in a real-life registry the proportion of patients with uncomplicated myocardial infarction (preserved left ventricular ejection fraction and no cardiovascular event within the first 6 months), and to report their characteristics, outcomes and beta-blocker use.

METHODS: We included 1887 consecutive patients with ST-segment elevation myocardial infarction from the prospective ePARIS registry. Patients were divided into three groups: the "uncomplicated myocardial infarction" group (n=1060), defined by a left ventricular ejection fraction ≥ 40% and a 6-month period free from cardiovascular events; the "complicated myocardial infarction" group (n=366), defined by a left ventricular ejection fraction ≥ 40% and a recurrent cardiovascular event in the first 6 months; and the "left ventricular dysfunction" group (n=461), defined by a left ventricular ejection fraction<40%.

RESULTS: During a median follow-up of 2.7 years (interquartile range 1.0-4.9 years), the "uncomplicated myocardial infarction" group was at low mortality risk compared with the "complicated myocardial infarction" group (hazard ratio 0.38, 95% confidence interval 0.25-0.58; P<0.01) and the "left ventricular dysfunction" group (hazard ratio 0.22, 95% confidence interval 0.15-0.32; P<0.01). Beta-blockers were prescribed at discharge predominantly in the "uncomplicated myocardial infarction" group (93%) compared with 87% in the "complicated myocardial infarction" group and 81% in the "left ventricular dysfunction" group.

CONCLUSIONS: Beta-blockers are less prescribed in patients who may need them the most. The benefit of beta-blockers-largely prescribed in lower-risk patients-remains to be shown beyond the first 6 months for these patients with no left ventricular dysfunction and no recurrent events.

ABSTRACT

Lipoxin A4 (LXA4) is one of the specialized pro-resolving lipid mediators proved to suppress the progression of atherosclerosis in vivo, but its clinical impacts in atherosclerotic patients is unclear. In this study, we assessed the prognostic impacts of LXA4 in patients with acute myocardial infarction (AMI). A total of 1569 consecutive AMI patients were prospectively recruited from March 2017 to January 2020. Plasma samples of AMI patients were collected, and LXA4 levels were determined using enzyme-linked immunosorbent assay. The primary outcome was major adverse cardiovascular event (MACE), a composite of all-cause death, recurrent MI, ischemic stroke, or ischemia-driven revascularization. Cox regression was used to assess associations between LXA4 and clinical outcomes. Overall, the median level of LXA4 was 5.637 (3.047-9.014) ng/mL for AMI patients. During a median follow-up of 786 (726-1108) days, high LXA4 (≥ 5.637 ng/mL) was associated with lower risk of MACE (hazard ratio [HR]: 0.73, 95% confidence interval [CI]: 0.60-0.89, P = 0.002), which was sustained in propensity score matching (HR: 0.73, 95% CI: 0.60-0.90, P = 0.004) and inverse probability weighting analysis (HR: 0.74, 95% CI: 0.61-0.90, P = 0.002). Combined with pro-inflammatory biomarker, patients with high levels of LXA4 (≥ 5.637 ng/mL) but low levels of high-sensitivity C-reactive protein (< 5.7 mg/L) acquired the lowest risk of MACE (HR: 0.68, 95% CI: 0.51-0.92, P = 0.012). In sum, high levels of LXA4 were associated with lower risk of recurrent ischemic events for AMI patients, which could serve as new therapeutic target to tackle cardiovascular inflammation.

ABSTRACT

The aim of this substudy of the EXAMINATION-EXTEND was to analyze 10-year outcomes according to the patient's age at the time of the first ST-elevation myocardial infarction (STEMI). Of 1,498 patients with STEMI included in the EXAMINATION-EXTEND study, those with a previous history of coronary ischemic even or ischemic stroke were excluded from this analysis. The remaining 1,375 patients were divided into 4 age groups: <55, 55 to 65, 65 to 75, and >75 years. The primary end point was 10-year patient-oriented composite end point (POCE) of all-cause death, any MI, or any revascularization. At 10-year follow-up, patients aged <55 years (adjusted hazard ratio [HR] 0.24, 95% confidence interval [CI] 0.18 to 0.31, p = 0.001), 55 to 65 years (adjusted HR 0.26, 95% CI 0.20 to 0.34, p = 0.001), and 65 to 75 years (adjusted HR 0.38, 95% CI 0.30 to 0.50, p = 0.001) showed lower risk of POCE than those aged >75 years, led by a lower incidence of all-cause death (<55 : 6% vs 55 to 65: 11.9% vs 65 to 75: 25.7% vs >75 years: 61.6%, p = 0.001). Cardiac death was more prevalent in the older group (<55: 3.7% vs 55 to 65: 5.8% vs 65 to 75: 10.9% vs >75 years: 35.5%, p = 0.001). In the landmark analyses, between 5- and 10-year follow-up, young patients exhibited a higher incidence of any revascularization (<55: 7.4% vs 55 to 65: 4.9% vs 65 to 75: 1.8% vs >65 years: 1.6%, p = 0.001). In conclusion, in patients with a first STEMI, advanced age was associated with high rates of POCE at 10-year follow-up due to all-cause and cardiac death. Conversely, younger patients exhibited a high risk of revascularization at long-term follow-up.

ABSTRACT

Background: Studies have shown that percutaneous coronary intervention (PCI) in long coronary artery lesions (≥30 mm) is associated with more frequent target vessel failure (TVF), and a significant proportion of patients have lesions that continue to induce ischemia after PCI (FFR ≤ 0.8). We investigated the impact of intravascular ultrasound (IVUS) on the functional PCI result and one-year TVF rate after the percutaneous treatment of long coronary artery lesions. Methods: A total of 80 patients underwent IVUS-guided PCI in long coronary artery lesions. The PCI results were validated with IVUS and FFR. Procedural outcomes were the proportion of patients with: (1) optimal physiology result (post PCI FFR value ≥ 0.9); (2) optimal anatomy result (all IVUS PCI optimization criteria met); and (3) optimal physiology and anatomy result. The clinical outcome was TVF during a one-year follow-up (target vessel (TV)-related death, TV myocardial infarction, ischemia-driven TV revascularization). Results: The mean stented segment length was 62 mm. The target vessel (TV) was the left anterior descending artery in 82.5% of cases. There were no patients with residual ischemia (FFR ≤ 0.8) after PCI. Optimal coronary flow (FFR ≥ 0.9) was achieved in 37.5%; optimal anatomy, as assessed by IVUS, was achieved in 68.4%; and both optimal flow and anatomy were achieved in 25% of patients. Target vessel failure during the 12-month follow-up was 2.5%. Conclusions: In the percutaneous treatment of very long coronary artery lesions, the use of IVUS guidance is associated with a low TVF rate during a one-year follow-up and no residual myocardial ischemia, as assessed by FFR.

ABSTRACT

BACKGROUND: Compared to bare-metal stent implantation, coronary drug-eluting stent (DES) implantation is more likely to reduce restenosis and the need for a subsequent repeat revascularization procedure. Diabetes increases the risk of coronary heart disease and the population of diabetic patients has increased significantly in China in recent years. It's essential to know more about the outcome in these patients underwent DES implantation. To date, the long-term safety and efficacy of coronary DES implantation in Chinese patients with diabetes has rarely been investigated.

METHODS: In this study, according to inclusion and exclusion criteria, 580 patients who underwent DES implantations between July 2014 and January 2016 were included and divided into the diabetic group (n=173) and non-diabetic group (n=407). Clinical baseline characteristics and follow-up outcomes were collected from electronic medical record. Serial clinical follow-up was conducted at 1-, 3-, and 5-year. The primary end point was a composite of major adverse cardiac events (MACEs), including cardiac death, recurrent myocardial infarction (re-MI), and target lesion revascularization (TLR) in 5-year follow-up. The long-term outcomes observed in the 5-year follow-up period were compared between the diabetic and non-diabetic patients.

RESULTS: Non-cardiac death was more common in the diabetic than non-diabetic patients in the 5-year follow-up period (8.7% vs. 3.2% P=0.00). Conversely, the risk of occurrence of MACEs, cardiac death, re-MI, and TLR were comparable. The all-cause mortality rate in 5-year follow-up was higher in the diabetic than non-diabetic patients (14.5% vs. 6.1%, P=0.00). The incidence of stent thrombosis was also comparable between the diabetic and non-diabetic patients.

CONCLUSIONS: Compared to the non-diabetic patients, the diabetic patients were at higher risk for all-cause mortality after coronary DES implantation during the long-term follow-up period.
