Project description:Coronary artery aneurysm (CAA) presenting as an ST-elevation myocardial infarction (STEMI) represents a clinical challenge due to the technical difficulties in the percutaneous management of this specific situation. Appropriate treatment for CAA depends on the precise clinical situation and consists of medical management, surgical resection, or/and stent placement. The high rate of complications during percutaneous intervention (distal thrombus embolization, no-reflow phenomenon, stent malposition, or dissection) makes emergent surgery a frequent situation in these cases. We present the case of a 50-year-old man with a STEMI due to thrombotic occlusion of CAA. Specific angiographic techniques and intracoronary imaging help with the percutaneous management of acute thrombotic occlusions in CAA, providing a less invasive approach than emergent surgery.

Project description:A 67-year-old man was transferred to our hospital because of anterior ST elevation myocardial infarction (STEMI). He had a history of a sirolimus-eluting stent implantation from the left main to the left anterior descending coronary artery (LAD) 9 years before and had undergone laparoscopic prostatectomy 8 days before in the setting of discontinuation of dual antiplatelet therapy. Emergent coronary angiography showed total occlusion in the distal LAD that was successfully treated by aspiration alone. Optical coherence tomography (OCT) showed no vulnerable lesion from the occluded lesion to the proximal LAD. OCT demonstrated that the thrombus attached to floating struts at the left main bifurcation and non-apposed struts at the left coronary ostium partly protruding to aorta, while the other struts were covered and well-apposed. Based on OCT findings, this case of STEMI was thought to be caused by distal embolism of a thrombus that formed at the stent site before it evolved into total occlusion. <Learning objective: We demonstrated how optical coherence tomography can be essential in revealing the underlying pathology. The patient showed an unusual manifestation of ST-elevation myocardial infarction caused by distal embolism of a thrombus that formed at the sirolimus-eluting stent due to dual antiplatelet therapy discontinuation during perioperative period. Optical coherence tomography revealed very late stent thrombosis at the left coronary ostium and could elucidate the underlying mechanism.>.

Project description:To assess safety of early discharge following primary percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction (STEMI).Retrospective analysis of prospectively collected data of 2448 STEMI patients treated with PPCI surviving to hospital discharge. Post-discharge all-cause mortality was reported at 1, 7, and 30 days and long-term follow up. A total of 1542 patients (63.0%) were discharged within 2 days of admission (early discharge group) and 906 patients (37.0%) after 2 days (late discharge group). In both groups, no deaths were recorded 1 day post discharge. The early and late discharge group mortality figures for 7 days were 0 and 4 patients (0.04%) and between 7 and 30 days were 11 (0.7%) and 11 patients (1.2%), respectively. During a mean follow up of 584 days, 178 patients (7.3%) died: 67 in the early discharge group (4.3%) and 111 in the late discharge group (12.3%).This exploratory, observational study demonstrates that discharging low-risk STEMI patients within 2 days following PPCI is safe. For providers of health care, early discharge can help to allay the cost of providing a 24-hour PPCI service and adds to the recognized benefits arising from PPCI.

Project description:As a result of increased life expectancy, octogenarians constitute an increasing proportion of patients admitted to hospital for ST-segment elevation myocardial infarction (STEMI). Primary percutaneous coronary intervention is currently the treatment of choice for octogenarians presenting with STEMI. The recent literature on this topic has yielded controversial results, even though advances in drug-eluting stents and new types of antithrombotic agents are improving the management of STEMI and postoperative care. In this paper, we review the current status of percutaneous coronary intervention in the elderly with STEMI, including the reasons for their high mortality and morbidity, predictors of mortality, and strategies to improve outcomes.

Project description:The treatment of ST-segment elevation myocardial infarction (STEMI) has advanced dramatically over the past 30 years since the introduction of reperfusion therapies, such that mechanical reperfusion with primary percutaneous coronary intervention is now the standard of care. With STEMI, as with other forms of acute coronary syndrome, stent deployment in culprit lesions is the dominant form of reperfusion in the developed world and is supported by contemporary guidelines. However, the precise timing of stenting and the extent to which both culprit and non-culprit lesions should be treated continue to be active areas of study. In this review, we revisit key data that support the use of mechanical reperfusion therapy in STEMI patients and explore the optimal timing for and extent of stent implantation in this complex patient group. We also review data surrounding the deleterious effects of untreated residual myocardial ischemia, the importance of complete revascularization, and the recent data exploring culprit-only versus multivessel stenting in the STEMI setting.

Project description:Percutaneous coronary intervention (PCI) is effective in opening the infarct related artery and restoring thrombolysis in myocardial infarction flow 3 (TIMI-flow 3) in large majority of ST-elevation myocardial infarction (STEMI). However there remain a small but significant proportion of patients, who continue to manifest diminished myocardial reperfusion despite successful opening of the obstructed epicardial artery. This phenomenon is called no-reflow. Clinically it manifests with recurrence of chest pain and dyspnea and may progress to cardiogenic shock, cardiac arrest, serious arrhythmias and acute heart failure. No reflow is regarded as independent predictor of death or recurrent myocardial infarction. No reflow is a multi-factorial phenomenon. However micro embolization of atherothrombotic debris during PCI remains the principal mechanism responsible for microvascular obstruction. This review summarizes the pathogenesis, diagnostic methods and the results of various recent randomized trials and studies on the prevention and management of no-reflow.

Project description:AimsThere are limited contemporary data on the use of initial fibrinolysis in ST-segment elevation myocardial infarction cardiogenic shock (STEMI-CS). This study sought to compare the outcomes of STEMI-CS receiving initial fibrinolysis vs. primary percutaneous coronary intervention (PPCI).MethodsUsing the National (Nationwide) Inpatient Sample from 2009 to 2017, a comparative effectiveness study of adult (>18 years) STEMI-CS admissions receiving pre-hospital/in-hospital fibrinolysis were compared with those receiving PPCI. Admissions with alternate indications for fibrinolysis and STEMI-CS managed medically or with surgical revascularization (without fibrinolysis) were excluded. Outcomes of interest included in-hospital mortality, development of non-cardiac organ failure, complications, hospital length of stay, hospitalization costs, use of palliative care, and do-not-resuscitate status.ResultsDuring 2009-2017, 5297 and 110 452 admissions received initial fibrinolysis and PPCI, respectively. Compared with those receiving PPCI, the fibrinolysis group was more often non-White, with lower co-morbidity, and admitted on weekends and to small rural hospitals (all P < 0.001). In the fibrinolysis group, 95.3%, 77.4%, and 15.7% received angiography, PCI, and coronary artery bypass grafting, respectively. The fibrinolysis group had higher rates of haemorrhagic complications (13.5% vs. 9.9%; P < 0.001). The fibrinolysis group had comparable all-cause in-hospital mortality [logistic regression analysis: 28.8% vs. 28.5%; propensity-matched analysis: 30.8% vs. 30.3%; adjusted odds ratio 0.97 (95% confidence interval 0.90-1.05); P = 0.50]. The fibrinolysis group had comparable rates of acute organ failure, hospital length of stay, rates of palliative care referrals, do-not-resuscitate status use, and lesser hospitalization costs.ConclusionsThe use of initial fibrinolysis had comparable in-hospital mortality than those receiving PPCI in STEMI-CS in the contemporary era in this large national observational study.

Project description:Preinfarction angina may act as a clinical surrogate of ischemic preconditioning that may reduce infarct size and improve mortality in the setting of thrombolytic therapy for ST-elevation myocardial infarction. However, the benefits of preinfarction angina in the setting of primary percutaneous coronary intervention with stenting is inconclusive because of the greater achievement of infarct artery patency and speed of reperfusion.To identify a homogeneous population, we performed a retrospective analysis of 1031 patients admitted with a first ST-elevation myocardial infarction with ischemic times between 1 and 6 hours who received primary percutaneous coronary intervention. We identified 245 patients who had occluded arteries on presentation, of which 79 patients had documented preinfarction angina defined as chest pain within 24 hours of infarction. Infarct size was measured as the peak creatine kinase level, a metric supported in a subgroup by late enhancement on cardiac magnetic resonance imaging. Patients with preinfarction angina (n=79) had a 50% reduction in infarct size compared with those patients without preinfarction angina (n=166) by both peak creatine kinase (1094±75 IU/L versus 2270±102 IU/L; P<0.0001) and creatine kinase area under curve (18 420±18 941 versus 36 810±21 741 IU/h per liter; P<0.0001) despite having identical ischemic times (185±8 minutes versus 181±5 minutes; P=0.67) and angiographic area at risk (24.1±1.2% versus 25.3±0.9%; P=0.43). There was an absolute 4% improvement in left ventricular ejection fraction before discharge in those patients with preinfarction angina (P<0.02).The occurrence of preinfarction angina is associated with significant myocardial protection in the setting of primary percutaneous coronary intervention with stenting during ST-elevation myocardial infarction. Because preinfarction angina is relatively common, it is important that these patients be identified in clinical trials investigating therapies designed to reduce reperfusion injury and infarct size.

Project description:Little is known about regional differences in volume, treatment, and outcomes of STEMI patients undergoing PCI during the pandemic. The objectives of this study were to compare COVID-19 pandemic and prepandemic periods with respect to regional volumes, outcomes, and treatment of patients undergoing percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) between January 1, 2019 and March 14, 2020 (pre-COVID period) and between March 15, 2020 and April 4, 2020 (COVID period) in 51 New York State hospitals certified to perform PCI. The hospitals were classified as being in either high-density or low-density COVID-19 counties on the basis of deaths/10,000 population. There was a decrease of 43% in procedures/week in high-density COVID-19 counties (p <0.0001) and only 4% in low-density counties (p = 0.64). There was no difference in the change in risk-adjusted in-hospital mortality rates in either type of county, but STEMI PCI patients in high-density counties had longer times from symptom onset to hospital arrival and lower cardiac arrest rates in the pandemic period. In conclusion, the decrease in STEMI PCIs during the pandemic was mainly limited to counties with a high density of COVID-19 deaths. The decrease appears to be primarily related to patients not presenting to hospitals in high-density COVID regions, rather than PCI being avoided in STEMI patients or a reduction in the incidence of STEMI. Also, high-density COVID-19 counties experienced delayed admissions and less severely ill STEMI PCI patients during the pandemic. This information can serve to focus efforts on convincing STEMI patients to seek life-saving hospital care during the pandemic.

Project description:Background: Primary percutaneous coronary intervention (PCI) is the most frequently used treatment modality for patients presenting with ST elevation myocardial infarction (STEMI). Current professional society guidelines recommend culprit artery only PCI. Recent evidence suggests the potential benefit of multivessel PCI among patients with STEMI that is not complicated by cardiogenic shock. Methods: We systematically searched PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials for clinical studies of patients with STEMI, not complicated by cardiogenic shock, who underwent primary PCI between January 1966 and January 2018. We evaluated all-cause and cardiovascular mortality, reinfarction, and repeat revascularization among patients randomized to a multivessel PCI strategy compared to a culprit artery only PCI strategy. Results: Four randomized clinical trials with a total of 1,044 patients met the inclusion criteria. Five hundred and sixty-six patients underwent multivessel PCI, and 478 patients underwent culprit artery only PCI. Multivessel PCI reduced all the studied endpoints: total death, cardiac death, reinfarction, and repeat revascularization (all P values <0.05). Conclusion: To our knowledge, this is the largest metaanalysis of randomized controlled trials studying multivessel PCI vs culprit artery only PCI in STEMI patients without shock, among whom lesion severity was graded by angiography alone. We found that compared to culprit artery only PCI, the multivessel PCI strategy was beneficial in reducing all-cause and cardiovascular mortality, reinfarction, and the need for repeat revascularization.
