RESUMO

AIMS: The purpose of this study was to verify the impact on the number and characteristics of coronary invasive procedures for acute coronary syndrome (ACS) of two hub centers with cardiac catheterization facilities, during the first month of lockdown following the COVID-19 pandemic. MATERIALS AND METHODS: Procedural data of ACS patients admitted between 10 March and 10 April 2020 were compared with those of the same period of 2019. RESULTS: We observed a 23.4% reduction in ACS admissions during 2020, with a decrease for both ST-elevation myocardial infarction (STEMI) (-5.6%) and non-ST-elevation myocardial infarction (-34.5%), albeit not statistically significant (P = 0.2). During the first 15 days of the examined periods, the reduction in ACS admissions reached 52.5% (-25% for STEMI and -70.3% for non-ST-elevation myocardial infarction, P = 0.04). Among STEMI patients, the rate of those with a time delay from symptoms onset longer than 180 min was significantly higher during the lockdown period (P = 0.01). Radiograph exposure (P = 0.01) was higher in STEMI patients treated in 2020 with a slightly higher amount of contrast medium (P = 0.1) and number of stents implanted (P = 0.1), whereas the number of treated vessels was reduced (P = 0.03). Percutaneous coronary intervention procedural success and in-hospital mortality were not different between the two groups and in STEMI patients (P NS for all). CONCLUSION: During the early phase, the COVID-19 outbreak was associated with a lower rate of admissions for ACS, with a substantial impact on the time delay presentation of STEMI patients, but apparently without affecting the in-hospital outcomes.

RESUMO

An increase in coronavirus disease (COVID-19) infections prompted Level 4 lockdown throughout New Zealand from 25 March 2020. We have investigated trends in coronary and electrophysiology (EP) procedures before and during this lockdown. The number of acute procedures for ST elevation myocardial infarction remained stable. In contrast, the number of in-patient angiograms and percutaneous intervention procedures fell by 53% compared with the previous 4 weeks in 2020 and by 56% compared with the corresponding period in 2019. Further study is required to determine the reasons for these trends.

RESUMO

Patients with acute coronary syndrome (ACS) have an increased serum level of calprotectin. The purpose of present study was to analyze the prognostic significance of serum calprotectin levels in elderly diabetic patients underwent percutaneous coronary intervention (PCI) due to ACS.A total of 273 consecutive elderly diabetic patients underwent PCI for primary ACS were enrolled. Serum calprotectin levels were measured before PCI, and baseline clinical characteristics of all patients were collected. All patients were followed up at regular interval for major adverse cardiovascular events (MACEs) during 1 year after PCI. MACEs include cardiovascular death, nonfatal myocardial infarction, and target vessel revascularization (TVR). The predicting value of serum calprotectin for MACEs was analyzed by using univariate and multivariate analysis and receiver-operating characteristic curve (ROC).At the endpoint of this study, 47 patients of all 273 patients had MACEs. According to optimal cutoff value of calprotectin for predicting MACEs by ROC analysis, all patients were stratified into a high calprotectin group and a low calprotectin group. The incidence rate of MACEs and TVR in high calprotectin group was prominently higher than that in low calprotectin group (21.9% vs 11.5%, P = .02). In multivariable COX regression analysis adjusting for potential confounders, serum calprotectin level remains as an independent risk predictor of MACE (hazard ratio, 1.56; 95% confidence interval [CI]: 1.08-4.62; P = .01).In diabetic patients with a comorbidity of ACS, a high serum level of calprotectin is associated to a higher MACE rate after PCI.

RESUMO

BACKGROUND: Prediabetes is an abnormal metabolic state that develops prior to the onset of diabetes with proven to common comorbid states of coronary artery disease. However, whether prediabetes worsens prognosis after percutaneous coronary intervention remains controversial. The aim of this study is to summarize previous cohort studies and to specify the impact of prediabetes on the long-term outcomes after percutaneous coronary intervention. METHODS: This meta-analysis will be performed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines for conducting and reporting meta-analysis data. Pubmed, Embase and Google scholar will be systematically searched, and supplemented with manual searches of the included reference lists to identify cohort studies. Pooled effects on the discontinuous variables will be expressed by adjusted hazard ratios with 95% confidence intervals. All analyses will be performed with Stata 15.0 (StataCorp LP, College Station, TX). RESULTS: The results of this study will be published in a peer-reviewed journal. CONCLUSION: This systematic review will provide new information and help enhance clinical decision-making on management of these patients. REGISTRATION NUMBER: INPLASY202060079.

RESUMO

The prognostic impact of incomplete revascularization (ICR) on patients underwent percutaneous coronary intervention (PCI) was vague. Our research aimed to objectify the level of ICR by residual SYNTAX score (rSS) and evaluate the impact of ICR on exercise tolerance.We enrolled 87 patients who completed cardiopulmonary exercise testing (CPET) within 12 months after PCI, retrospectively. According to rSS, patients were divided into rSS = 0 group, 0 < rSS ≤ 8 group, and rSS > 8 group. The CPET variables--including peak metabolic equivalent (METpeak), percentages of predicting value of METpeak (METpeak%pred), MET at anaerobic threshold (AT), peak oxygen uptake (VO2peak), percentages of predicting value of VO2peak (VO2peak%pred), VO2 at AT--were collected and compared.Among rSS = 0, 0 < rSS ≤ 8 and rSS > 8 groups, patients with higher rSS had progressively lower METpeak, METpeak%pred, VO2peak%pred, VO2 at AT, and MET at AT, which indicate reduced exercise tolerance. And further multiple comparisons showed that there were no statistically significant differences between rSS = 0 and 0 < rSS ≤ 8 groups, while the aforementioned CPET variables were significantly lower in rSS > 8 group compared with rSS = 0 group. Logistic regression analysis showed that rSS was an independent risk factor for reduced exercise tolerance.

RESUMO

Patients resuscitated from cardiac arrest require complex management. An organized approach to early postarrest care can improve patient outcomes. Priorities include completing a focused diagnostic work-up to identify and reverse the inciting cause of arrest, stabilizing cardiorespiratory instability to prevent rearrest, minimizing secondary brain injury, evaluating the risk and benefits of transfer to a specialty care center, and avoiding early neurologic prognostication.

RESUMO

Intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) has been shown in clinical trials, registries, and meta-analyses to reduce recurrent major adverse cardiovascular events after PCI. However, IVUS utilization remains low. An increasing number of high-risk or complex coronary artery lesions are treated with PCI, and we hypothesize that the impact of IVUS in guiding treatment of these complex lesions will be of increased importance in reducing major adverse cardiovascular events while remaining cost-effective. The "IMPact on Revascularization Outcomes of intraVascular ultrasound-guided treatment of complex lesions and Economic impact" trial (registered on clinicaltrials.gov: NCT04221815) is a multicenter, international, clinical trial randomizing subjects to IVUS-guided versus angiography-guided PCI in a 1:1 ratio. Patients undergoing PCI involving a complex lesion are eligible for enrollment. Complex lesion is defined as involving at least 1 of the following characteristics: chronic total occlusion, in-stent restenosis, severe coronary artery calcification, long lesion (≥28 mm), or bifurcation lesion. The clinical investigation will be conducted at approximately 120 centers in North America and Europe, enrolling approximately 2,500 to 3,100 randomized subjects with an adaptive design. The primary clinical end point is the rate of target vessel failure at 12 months, defined as the composite of cardiac death, target vessel-related myocardial infarction, and ischemia-driven target vessel revascularization. The co-primary imaging end point is the final post-PCI minimum stent area assessed by IVUS. The primary objective of this study is to assess the impact of IVUS guidance on the PCI treatment of complex lesions.

RESUMO

BACKGROUND: The clinical value of intracoronary imaging for percutaneous coronary intervention (PCI) guidance is well acknowledged. Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) are the most commonly used intravascular imaging to guide and optimize PCI in day-to-day practice. However, the comparative effectiveness of IVUS-guided versus OCT-guided PCI with respect to clinical end points remains unknown. METHODS AND DESIGN: The OCTIVUS study is a prospective, multicenter, open-label, parallel-arm, randomized trial comparing the effectiveness of 2 imaging-guided strategies in patients with stable angina or acute coronary syndromes undergoing PCI in Korea. A total of 2,000 patients are randomly assigned in a 1:1 ratio to either an OCT-guided PCI strategy or an IVUS-guided PCI strategy. The trial uses a pragmatic comparative effectiveness design with inclusion criteria designed to capture a broad range of real-world patients with diverse clinical and anatomical features. PCI optimization criteria are predefined using a common algorithm for online OCT or IVUS. The primary end point, which was tested for both noninferiority (margin, 3.1 percentage points for the risk difference) and superiority, is target-vessel failure (cardiac death, target-vessel myocardial infarction, or ischemia-driven target-vessel revascularization) at 1 year. RESULTS: Up to the end of July 2020, approximately 1,200 "real-world" PCI patients have been randomly enrolled over 2 years. Enrollment is expected to be completed around the midterm of 2021, and primary results will be available by late 2022 or early 2023. CONCLUSION: This large-scale, multicenter, pragmatic-design clinical trial will provide valuable clinical evidence on the relative efficacy and safety of OCT-guided versus IVUS-guided PCI strategies in a broad population of patients undergoing PCI in the daily clinical practice.

RESUMO

About half of patients with acute ST-segment elevation myocardial infarction (STEMI) present with multivessel coronary artery disease (MVD). Recent evidence supports complete revascularization in these patients. However, optimal timing of non-culprit lesion revascularization in STEMI patients is unknown because dedicated randomized trials on this topic are lacking. STUDY DESIGN: The MULTISTARS AMI trial is a prospective, international, multicenter, randomized, two-arm, open-label study planning to enroll at least 840 patients. It is designed to investigate whether immediate complete revascularization is non-inferior to staged (within 19-45 days) complete revascularization in patients in stable hemodynamic conditions presenting with STEMI and MVD and undergoing primary percutaneous coronary intervention (PCI). After successful primary PCI of the culprit artery, patients are randomized in a 1:1 ratio to immediate or staged complete revascularization. The primary endpoint is a composite of all-cause death, non-fatal myocardial infarction, ischemia-driven revascularization, hospitalization for heart failure, and stroke at 1 year. CONCLUSIONS: The MULTISTARS AMI trial tests the hypothesis that immediate complete revascularization is non-inferior to staged complete revascularization in stable patients with STEMI and MVD.

RESUMO

BACKGROUND: Patients aged ≥80 years are often treated with new-generation drug-eluting stents (DES), but data from randomized studies are scarce owing to underrepresentation in most trials. We assessed 1-year clinical outcome of octogenarians treated with new-generation DES versus younger patients. METHODS: We pooled patient-level data of 9,204 participants in the TWENTE, DUTCH PEERS, BIO-RESORT, and BIONYX (TWENTE I-IV) randomized trials. The main clinical end point was target vessel failure (TVF), a composite of cardiac death, target vessel-related myocardial infarction (MI), or clinically indicated target vessel revascularization. RESULTS: The 671 octogenarian trial participants had significantly more comorbidities. TVF was higher in octogenarians than in 8,533 patients <80 years (7.3% vs 5.3%, hazard ratio [HR]: 1.36, 95% CI: 1.0-1.83, P = .04). The cardiac death rate was higher in octogenarians (3.9% vs 0.8%, P < .001). There was no significant between-group difference in target vessel MI (2.3% vs 2.3%, P = .88) and repeat target vessel revascularization (1.9% vs 2.8%, P = .16). In multivariate analyses, age ≥ 80 years showed no independent association with TVF (adjusted HR: 1.04, 95% CI: 0.76-1.42), whereas the risk of cardiac death remained higher in octogenarians (adjusted HR: 3.38, 95% CI: 2.07-5.52, P < .001). In 6,002 trial participants, in whom data on major bleeding were recorded, octogenarians (n = 459) showed a higher major bleeding risk (5.9% vs 1.9%; HR: 3.08, 95% CI: 2.01-4.74, P < .001). CONCLUSIONS: Octogenarian participants in 4 large-scale randomized DES trials had more comorbidities and a higher incidence of the main end point TVF. Cardiac mortality was higher in octogenarians, whereas there was no increase in MI or target vessel revascularization rates. Treatment of octogenarian patients with new-generation DES appears to be safe and effective.

RESUMO

BACKGROUND The efficacy of telemedicine in reducing delay times and short-term adverse clinical outcomes in patients with ST segment elevation myocardial infarction (STEMI) during the coronavirus disease 2019 (COVID-19) pandemic is unclear. This study compared outcomes in patients with STEMI who had percutaneous coronary intervention (PCI) and the use of a telemedicine app from August 2019 to March 2020 at a single center in Beijing, China. MATERIAL AND METHODS A total of 243 patients with STEMI who underwent PCI were consecutively enrolled and divided into 2 groups according to the date, before or after the pandemic. The 2 groups were further divided into patients who used the app for consulting and those who did not. RESULTS The time from symptom onset to calling an ambulance (SCT), door to balloon time (DTB), and total ischemia time (TIT) were significantly prolonged in patients after the pandemic. Patients who used the app had shorter SCT, DTB, and TIT before and after the pandemic compared to those who did not. Adverse clinical outcomes were significantly higher after compared with before the pandemic, despite the incidence rate of stroke, any revascularization, and stent thrombosis. However, there was no significant difference in short-term adverse clinical outcomes between patients who used the app and those who did not before and after the pandemic. CONCLUSIONS Telemedicine reduced the delay time of STEMI patients during the COVID-19 pandemic. The difference in short-term adverse clinical outcomes was not statistically significant between patients who used the app and those who did not.

RESUMO

Background: The white blood cell count to mean platelet volume ratio (WMR) is an indicator of inflammation in patients with atherosclerotic disease. Residual SYNTAX Score (RSS) is an objective measure of degree and complexity of residual stenosis after percutaneous coronary intervention (PCI). We investigated the relationship between WMR and clinical prognosis and RSS in patients undergoing primary percutaneous coronary intervention (P-PCI). Method: Between June 2015 and December 2018, 537 patients who underwent primary PCI were evaluated for in-hospital events, and 477 patients were evaluated for clinical events during follow-up after discharge. The endpoint of our study is major adverse cardiac events (MACEs) seen in the in-hospital and follow-up periods. Results: In our study, 537 patients were stratified into two groups according to admission median WMR. There were 268 patients in the low WMR group (WMR < 1286) and 269 patients in the high WMR group (WMR ≥ 1286). RSS (p = 0.01) value of the high WMR group was higher than that of the low WMR group. The rates of in-hospital MACE (p = 0.001), cardiac death (p < 0.001), decompansated heart failure (0.007), and ventricular tachycardia/fibrillation (p = 0.003) were higher in the high WMR group than in the low WMR group. The follow-up MACEs (p = 0.043), cardiac death (p = 0.026), and reinfarction (p = 0.031) ratio were higher in the high WMR group. In ROC analysis, cut-off values of in-hospital and follow-up MACEs were >1064 (sensitivity: 83.12%, and specificity: 36.29%) and >1130 (sensitivity: 69.15%, and specificity: 44.91%), respectively. The Kaplan-Meier analysis showed that the high WMR group had the significantly lowest MACE-free survival rate (log-rank test, p = 0.006). A moderate correlation was observed between WMR and RSS (r: 456, p = 0.002). Conclusion: A higher WMR value on admission was associated with worse outcomes in patients with P-PCI and independently predicted for follow-up MACEs. The WMR provides both a rapid and an easily obtainable parameter to identify reliably high-risk patients who underwent primary percutaneous coronary intervention due to STEMI.

RESUMO

The ongoing coronavirus disease 2019 pandemic has resulted in additional challenges for systems designed to perform expeditious primary percutaneous coronary intervention for patients presenting with ST-segment-elevation myocardial infarction. There are 2 important considerations: the guideline-recommended time goals were difficult to achieve for many patients in high-income countries even before the pandemic, and there is a steep increase in mortality when primary percutaneous coronary intervention cannot be delivered in a timely fashion. Although the use of fibrinolytic therapy has progressively decreased over the last several decades in high-income countries, in circumstances when delays in timely delivery of primary percutaneous coronary intervention are expected, a modern fibrinolytic-based pharmacoinvasive strategy may need to be considered. The purpose of this review is to systematically discuss the contemporary role of an evidence-based fibrinolytic reperfusion strategy as part of a pharmacoinvasive approach, in the context of the emerging coronavirus disease 2019 pandemic.

RESUMO

Objective: To investigate the effects of clopidogrel resistence and CYP2C19 genotype on the clinical prognosis of acute coronary syndrome(ACS) patients undergoing percutaneous coronary intervention(PCI). Methods: This study was a retrospective cohort study. ACS patients who underwent PCI in Beijing Anzhen Hospital from October 2015 to January 2017 were recruited. The inhibition rate of adenosine diphosphate(ADP) was monitored by thromboelastography. All of these patients were divided into clopidogrel resistance and non-resistance group according to the monitoring results. CYP2C19 genotype was detected by TaqMan probe-based real-time quantitative PCR. Patients were divided into slow, medium and fast metabolic group, according to the CYP2C19 genotype. After 12 months of follow-up, the end points included all-cause death, cardiac death, angina, myocardial infarction, stent thrombosis, ischemic stroke and hemorrhage were collected. Combined thrombotic events were defined as a composite of angina, myocardial infarction, stent thrombosis and ischemic stroke. The differences of the incidence of clinical events between groups were compared. Cox regression was used to analyze the effects of clopidogrel resistance and CYP2C19 genotype on the combined thrombotic events, cardiac death and hemorrhage. Results: A total of 1 696 patients were included, and the age was (59.4±9.6) years, with 1 280(75.5%) males. There were 471 cases(27.8%) in clopidogrel resistance group, and 1 225 cases(72.2%) in clopidogrel non-resistance group. There were 218 patients(12.9%) were in slow metabolic group, 668(39.4%) in medium metabolic group, and 810 (47.8%) in fast metabolic group. The median follow-up time was 13.3 months, and 131 cases were lost to follow-up, with a loss follow-up rate of 7.7%. Compared with the clopidogrel non-resistance group, the clopidogrel resistance group had a higher incidence of myocardial infarction(7.6%(36/471) vs. 5.1%(62/1 225), P=0.041), a lower incidence of hemorrhage (13.2%(62/471) vs. 17.9%(219/1 225), P=0.020) and minor hemorrhage(11.5%(54/471) vs. 15.8% (194/1 225), P=0.022). There were no statistically significant difference in all-cause death, cardiac death, angina, stent thrombosis, ischemic stroke and severe bleeding between clopidogrel resistance and non-resistance group(all P>0.05). There was no statistically significant difference in the incidence of endpoint events among different CYP2C19 genotypes (all P>0.05). Cox regression analysis showed that clopidogrel resistance was an independent factor of combined thrombotic events (OR=2.334, 95%CI 1.215-4.443, P=0.016) and bleeding events (OR=0.481, 95%CI 0.174-0.901, P=0.023). While CYP2C19 genotype was not independent factor for combined thrombotic events, cardiac death and hemorrhage (all P>0.05). Conclusion: For ACS patients after PCI, clopidogrel resistance can increase the risk of combined thrombotic events, but also reduce the risk of bleeding; while CYP2C19 genotype is not an independent factor for clinical prognosis.

RESUMO

de Winter syndrome is a special equivalent of anterior ST-segment elevation myocardial infarction (STEMI) characterized by the absence of overt ST-elevation with upsloping ST-segment depression followed by tall symmetrical T-waves in the precordial leads, often associated with total occlusion of the proximal left anterior descending coronary artery. Herein we present a case of de Winter syndrome in a 63-year-old man, whose initial ECG showed no ST-segment elevation, but subsequent coronary angiography confirmed total occlusion of the proximal LAD coronary artery. The patient was successfully treated via mechanical reperfusion therapy and stenting through percutaneous coronary intervention (PCI). de Winter syndrome is associated with a high mortality often due to insufficient awareness of this condition by clinicians. Immediate reperfusion therapy by PCI is the life-saving treatment for the patients diagnosed with this syndrome, and prompt recognition of the ECG pattern is critical to ensure the timely administration of the therapy.

RESUMO

Bleeding complication has been considered as a serious problem in current percutaneous coronary interventions (PCI). Fortunately, several groups have already reported the effectiveness of protamine use just after PCI to immediately remove any arterial sheath. However, there is a concern that protamine reversal may increase non-occlusive thrombus and, in turn, lead to mid-term cardiovascular events such as target vessel revascularization (TVR) or stent thrombosis. Thus, the purpose of this study was to evaluate whether protamine use following elective PCI was associated with mid-term clinical outcomes. In total, 472 patients were included in this study; subsequently, they were divided into protamine group (n = 142) and non-protamine group (n = 330). The primary endpoint was the composite of ischemia-driven TVR and stent thrombosis. The median follow-up period was determined to be at 562 days. In total, 32 primary endpoints were observed during the study period, and the incidence of primary endpoints tended to be greater in the protamine group than in the non-protamine group (P = 0.056). However, the lesion length, the degree of calcification, and the prevalence of hemodialysis were significantly determined greater in the protamine group than in the non-protamine group. In the multivariate Cox proportional hazards model, the use of protamine (versus non-protamine: hazard ratio 0.542 and 95% confidence interval 0.217-1.355, P = 0.191) was deemed not to be associated with the primary endpoint after controlling legion length, calcification, and hemodialysis. In conclusion, immediate protamine use following elective PCI did not increase mid-term ischemia-driven TVR or stent thrombosis. However, immediate protamine use after PCI should be discussed further for the safety of the patient.

RESUMO

Since the number of elderly patients suffering from acute myocardial infarction (AMI) has been increasing in developed countries, primary percutaneous coronary intervention (PCI) for the very elderly aged ≥80 years old is already common. The study aimed to examine the determinants of in-hospital death among the very elderly with AMI in current PCI era. We included 412 consecutive AMI patients aged ≥ 80 years old who received PCI to the culprit lesion; however, 42 patients (10.2%) died during the index hospitalization. Thus, univariate and multivariate logistic regression analyses were performed to identify the determinants of in-hospital death. Of note, the modified KATZ index, which is a seven-point scale ranging from 0 to 6 (0 point indicating no dependence and six points indicating full dependence), was calculated to evaluate pre-admission activity of daily living (ADL). In multivariate analysis, cardiac arrest (OR 4.642, 95% CI 1.177-18.305, P = 0.028), Killip class IV (versus Killip class I: OR 5.732, 95% CI 1.076-16.630, P = 0.001), modified KATZ index (OR 1.212, 95% CI 1.001-1.469, P = 0.049), hemoglobin levels (OR 0.803, 95% CI 0.656-0.983, P = 0.033), use of temporary pacemaker (OR 2.603, 95% CI 1.010-6.709, P = 0.048), final Thrombolysis In Myocardial Infarction (TIMI) flow grade 3 (versus TIMI ≤ 2: OR 0.240, 95% CI 0.093-0.618, P = 0.003), and mechanical circulatory support (OR 4.264, 95% CI 1.818-10.005, P = 0.001) were found to be significantly associated with in-hospital death. In conclusion, in-hospital outcomes of the very elderly with AMI were still poor in the current PCI era. Poor pre-admission ADL as well as cardiogenic shock and anemia were determined to be strongly associated with in-hospital death.
