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

AIM: Takotsubo syndrome (TS) mimics acute coronary syndrome but has a distinct pathophysiology. This study aimed to compare and contrast the clinical presentation, management and outcomes of patients with TS in five large New Zealand hospitals. METHODS: We identified 632 consecutive patients presenting to the five major tertiary hospitals in New Zealand (Middlemore Hospital, Auckland City Hospital, North Shore Hospital, Christchurch Hospital and Dunedin Hospital) between January 2006 and June 2018 and obtained clinical, laboratory, electrocardiography, echocardiography, coronary angiography and long-term follow-up data. RESULTS: Six hundred and thirty-two consecutive patients with TS (606 women, mean age 65.0+11.1 years) were included. An associated stressor was identified in two-thirds of patients, and emotional triggers were more frequent than physical triggers (62.9% and 37.1%, respectively). Overall, 12.7% of patient had depression and 11.7% anxiety but this was more common in patients from Christchurch Hospital (20.4% and 23.4%, respectively). The in-hospital mortality among the five hospitals ranges between 0 to 2.0%. The mean follow-up was 4.9+3.4 years (median 4.4 years). Fifty-four people died post-discharge, all but one from a non-cardiac cause. Forty patients had recurrent TS. Mortality post-discharge (p=0.63) and TS recurrence (p=0.38) did not differ significantly among the five hospitals. CONCLUSION: In this large New Zealand TS cohort, the clinical characteristics and presentation were similar among the five hospitals. A subset of patients had a complicated in-hospital course, but late deaths were almost all from non-cardiac causes and recurrence was infrequent. Mortality post-discharge and recurrence was similar between the hospitals.

RESUMO

There has been a huge impact of the COVID-19 pandemic on global healthcare systems. Advisories across the world have appealed to people to stay at home and observe social distancing to slow down the pandemic. However it is important to realize as to how this is affecting acute cardiovascular care. Recent studies from Europe and USA have reported > 50% reduction in hospital admissions for ACS and declining rates of coronary interventions. The possible reasons for this noticeable reduction in patients with ACS/STEMI during the COVID-19 pandemic are multi-factorial. On one hand, it is due to change in thresholds for referring patients of ACS/STEMI for cardiac catheterization, with fibrinolysis being acceptable for many stable STEMI patients and conservative management being preferred for NSTEMI patients. Theories abound on how "staying at home" strategy may have led to an reduction in acute coronary events due to healthier lifestyle, better compliance and reduced stress. Realistically however, a more disquieting reason would be a "pseudo-reduction" ie. the incidence of ACS/STEMI is actually the same, but these patients are staying away from hospitals due to fear of contracting the infection. Lockdown restrictions have also limited transport options for patients seeking to reach hospitals in time. Healthcare systems need to be prepared for an anticipated downstream deluge of such untreated patients who may present with sequelae like heart failure, reinfarction, arrhythmias, mechanical complications etc. Scientific societies should have proactive campaigns to alleviate patient concerns, and encourage them to seek timely medical attention despite the COVID-19 pandemic.

RESUMO

Prompt identification of acute coronary syndrome is a challenge in clinical practice. The 12-lead electrocardiogram (ECG) is readily available during initial patient evaluation, but current rule-based interpretation approaches lack sufficient accuracy. Here we report machine learning-based methods for the prediction of underlying acute myocardial ischemia in patients with chest pain. Using 554 temporal-spatial features of the 12-lead ECG, we train and test multiple classifiers on two independent prospective patient cohorts (n = 1244). While maintaining higher negative predictive value, our final fusion model achieves 52% gain in sensitivity compared to commercial interpretation software and 37% gain in sensitivity compared to experienced clinicians. Such an ultra-early, ECG-based clinical decision support tool, when combined with the judgment of trained emergency personnel, would help to improve clinical outcomes and reduce unnecessary costs in patients with chest pain.

RESUMO

A pandemic of Coronavirus-19 disease was declared by the World Health Organization on March 11, 2020. The pandemic is expected to place unprecedented demand on health service delivery. This position statement has been developed by the Cardiac Society of Australia and New Zealand to assist clinicians to continue to deliver rapid and safe evaluation of patients presenting with suspected acute cardiac syndrome at this time. The position statement complements, and should be read in conjunction with, the National Heart Foundation of Australia & Cardiac Society of Australia and New Zealand: Australian Clinical Guidelines for the Management of Acute Coronary Syndromes 2016: Section 2 'Assessment of Possible Cardiac Chest Pain'.

RESUMO

Background: Familial hypercholesterolemia (FH) is a genetic disorder characterized by high levels of low-density lipoprotein cholesterol (LDL-C). Because of underdiagnosis, acute coronary syndrome (ACS) is often the first clinical manifestation of FH. In Japan, there are few reports on the prevalence and diagnostic ratios of FH and the proportion of ACS among FH patients in clinical settings. Methods: This retrospective, observational study used anonymized data from electronic healthcare databases between April 2001 and March 2015 of patients who had ≥2 LDL-C measurements recorded after April 2009. The index date was defined as the date of the first LDL-C measurement after April 2009. The primary endpoint was the prevalence of definite or suspected FH; secondary endpoints included the proportion of FH patients hospitalized for ACS, the proportion of patients using lipid-lowering drugs (LLDs), and LDL-C levels. Results: Of the 187,781 patients screened, 1547 had definite or suspected FH (0.8%) based on data from the entire period; 832 patients with definite (n = 299, 0.16%) or suspected FH (n = 533, 0.28%) before the index date were identified in the main analysis cohort. LLDs were used in 214 definite FH patients (71.6%) and 137 suspected FH patients (25.7%). Among definite or suspected FH patients with ACS (n = 84) and without ACS (n = 748), 32.1% and 30.1% with definite FH and 3.2% and 2.4% with suspected FH had LDL-C levels < 2.6 mmol/L (<100 mg/dL), respectively. Sixty patients (7.2%) were hospitalized due to ACS at the index date. Conclusions: The prevalence of FH in this Japanese cohort of patients with ≥2 LDL-C measurements at hospitals was 0.8%, which is higher than that currently reported in epidemiological studies (0.2-0.5%). Patients with suspected FH, with or without ACS, had poorly controlled LDL-C levels and were undertreated. The proportion of FH patients who were hospitalized due to ACS was 7.2%.

RESUMO

The prevalence of coronary artery disease is increasing in young adults. We evaluated the outcomes of different types of acute coronary syndrome in 917 patients undergoing coronary angiography aged ≤45 years. Male sex, smoking, dyslipidemia were the most important risk factors. ST-elevation myocardial infarction (STEMI; 54.8%) predominated. The STEMI patients had higher risk of hospital mortality (3.6% vs 0.6%; P = .004) and major adverse cardiac and cerebrovascular events (MACCE; 13.8% vs 3.3%; P < .001, hazard ratio [HR], 4.65; 95% CI, 2.45-8.82). Presentation heart rate, blood pressure, heart failure, shock, arrhythmia, ejection fraction (EF), diabetes, contrast-induced nephropathy (CIN), and elevated troponin were associated with hospital mortality and MACCE. But only heart failure (HR, 5.816; 95% CI, 2.254-15.008) and CIN (HR, 6.241; 95% CI, 2.340-16.641) were independent risk factors for hospital MACCE. There was no difference in long-term mortality between the 2 groups, but non-STEMI patients had higher risk for MACCE after 3 years (14.4% vs 9.9%, P = .033). Although shock (HR, 0.814; 95% CI, 0.699-0.930), Killip class ≥2 (HR, 0.121; 95% CI, 0.071-0.170), CIN (HR, 0.323; 95% CI, 0.265-0.380), and EF (HR, 0.917; 95% CI, 0.854-0.984) were independent predictors of hospital death, only EF was the independent predictor of long-term mortality (HR, 0.897; 95% CI, 0.852-0.944).

RESUMO

In patients with unstable angina pectoris (UAP) or non-ST elevation myocardial infarction (NSTEMI), long-term mortality remains high despite improvements in the diagnosis and treatment. In this study, we investigated whether serum albumin level is a useful predictor of long-term mortality in patients with UAP/NSTEMI. Consecutive patients (n = 403) who were hospitalized with a diagnosis of UAP/NSTEMI were included in the study. Patients were divided into 2 groups based on the presence of hypoalbuminemia and the relationship between hypoalbuminemia and mortality was analyzed. Hypoalbuminemia was detected in 34% of the patients. The median follow-up period was 35 months (up to 45 months). Long-term mortality rate was 32% in the hypoalbuminemia group and 8.6% in the group with normal serum albumin levels (P < .001). On multivariate analysis, hypoalbuminemia, decreased left ventricular ejection fraction, and increased age were found to be independent predictors of mortality (P < .05). The cutoff value of 3.10 g/dL for serum albumin predicted mortality with a sensitivity of 74% and specificity of 67% (receiver-operating characteristic area under curve: 0.753, 95% CI: 0.685-0.822). All-cause long-term mortality rates were significantly increased in patients with hypoalbuminemia. On-admission albumin level was an independent predictor of mortality in patients with UAP/NSTEMI.

RESUMO

Background There is lack of prospective data on evolution within one year of acute coronary syndromes (ACS) in a representative population of Brazilian patients. Objectives To assess the prescription of evidence-based therapies, the incidence of severe outcomes and the predictors for these outcomes in a multicenter Brazilian registry of ACS patients. Methods The ACCEPT is a prospective observational study, which included patients hospitalized with a diagnostic of ACS in 47 Brazilian hospitals. The patients were followed for a 1 year and data were collected on the medical prescription and the occurrence of major cardiovascular events (cardiovascular mortality, reinfarction and cerebrovascular accident - CVA). Values of p < 0.05 were considered statistically significant. Results A total of 5,047 patients were included in this registry from August 2010 to April 2014. The diagnosis of ACS was confirmed in 4,782 patients (94.7%) and, among those, the most frequent diagnosis was ACS with ST segment elevation (35.8%). The rate of major cardiovascular events was 13.6 % within 1 year. Adherence to prescription of evidence-based therapy at admission was of 62.1%. Age, public service, acute myocardial infarction, CVA, renal failure, diabetes and quality of therapy were associated independently with the occurrence of major cardiovascular events. Conclusions During the one-year follow-up of the ACCEPT registry, more than 10% of the patients had major cardiovascular events and this rate ranged according with the quality of therapy. Strategies must be elaborated to improve the use of evidence-based therapies to minimize the cardiovascular events among the Brazilian population. (Arq Bras Cardiol. 2020; 114(6):995-1003).

RESUMO

COVID-19 pandemic is creating havoc in the world. It is also spreading in India creating a massive healthcare problem. Few major hospitals were closed down because of the spread among healthcare personnel. Management of several commonly occurring diseases needed modifications to a lesser or greater extent because of this pandemic. Management of acute coronary syndrome (ACS) also requires certain modifications. In this opinion paper an attempt has been made to give an outline of ACS management in this changed scenario.

RESUMO

BACKGROUND: There is limited evidence of non-ST elevation acute coronary syndrome (NSTE-ACS) in patients aged 80 or older in Vietnam. AIM: To describe the clinical characteristics of patients aged≥80 with NSTE-ACS in Vietnam, and to examine the effect of percutaneous coronary intervention (PCI) on adverse outcomes. METHODS: Consecutive patients aged ≥80 with a diagnosis of NSTE-ACS admitted to two tertiary hospitals in Vietnam from 12/2018 to 06/2019 were recruited. The major outcomes were: (1) the composite of all-cause mortality, recurrent myocardial infarction and stroke, (2) re-admission rate during 3 months. Cox proportional-hazards regressions were conducted to examine the impact of PCI on the study outcomes, with results presented as hazard ratios (HR) and 95% confidence intervals (CI). RESULTS: There were 120 participants, mean age 84.8 ± 3.8, 50% were female. Angiography and PCI were performed in 42 participants (35.0%). Most of the participants had multimorbidity and multiple coronary vessel disease. Compared to participants who did not receive PCI, participants who received PCI had significantly lower rates of adverse events during hospitalisation and during 3 months of follow up. Cox proportional hazards models adjusted to age and GRACE score show that PCI was significantly associated with reduced the composite outcome of all-cause mortality, recurrent myocardial infarction and stroke during 3 months follow-up (adjusted HR 0.32, 95%CI 0.12-0.86). PCI was also associated with reduced re-admission. CONCLUSIONS: The rate of PCI was low in the very elderly patients with NSTE-ACS in this study, although PCI was significantly associated with reduced adverse outcomes.

RESUMO

During the early phase of the lockdown following the COVID-19 pandemic, an alarm on the impact on cardiology admissions for cardiac causes, particularly in the field of acute coronary syndromes (ACS), has emerged. In order to evaluate this trend, we analyzed the literature data published since the beginning of the COVID-19 pandemic to date, in addition to our intensive cardiac care unit (ICCU) experience. This analysis showed (i) a reduction of the overall ICCU admissions up to 50%; (ii) a 40-50% reduction of ACS admissions, greater for non-ST-elevation myocardial infarction (NSTEMI) than for ST-elevation myocardial infarction (STEMI); (iii) a reduction greater than 50% of coronary angiography and percutaneous coronary angioplasty; (iv) a higher time delay of STEMI; and (v) a higher number of ICCU admissions for non-primarily cardiac problems. In conclusion, the lockdown imposed due to the spread of COVID-19 infection has led to a change in the number and type of cardiology admissions. It seems therefore necessary that patients, especially for time-dependent diseases such as ACS, continue to refer to hospital care; that contemporary standard of care for acute cardiac disease should be guaranteed, and that intensivist cardiologists acquire specific skills for the treatment of patients with clinical conditions normally treated by other specialists.

RESUMO

A high incidence of thrombotic events, particularly deep vein thrombosis and pulmonary embolism, has been clearly documented in COVID-19 patients. In addition, small series of patients with coronary, cerebrovascular and peripheral arterial thrombotic events have also been reported, but their true incidence and consequences are not well described, and constitute the objective of this study. From February 1st to April 21st, 2020, 2115 COVID-19 patients were treated at Hospital Universitario Fundación Alcorcón (Madrid, Spain), and 1419 were eventually admitted. Patient characteristics and outcomes were collected by reviewing their electronic medical records. Fourteen patients had a systemic arterial thrombotic event, which represents a 1% incidence in relation to the total number of hospitalized patients. Three patients suffered an acute coronary syndrome, two with persistent ST-segment elevation, one of whom was treated invasively, and one with transient ST-segment elevation. Eight patients had a cerebrovascular event. Six suffered an acute ischemic stroke and two a transient ischemic attack, 50% of them had a Rankin score ≥ 3 at discharge. Three additional patients had a limb thrombotic event, all of them infrapopliteal, and were managed conservatively. All three cases developed necrosis of the toes, two of them with bilateral involvement. The hospitalization death rate of patients with an arterial event was 28.6%. Although COVID-19 may favor the occurrence of thrombotic events, the destabilization and thrombosis of arterial atherosclerotic plaques do not seem to be a frequent mechanism which warrants the need for specific systematic preventive measures.

RESUMO

AIM: The purpose of the study was to analyse clinical peculiarities of the development of acute coronary syndrome in patients after coronary artery bypass grafting procedures and to evaluate the in-hospital results of treatment PATIENTS AND METHODS: Within the frameworks of a single-centre register over the period from 2006 to 2016 the study included 81 patients (with a total of more than 5000 coronary artery bypass grafting operations performed during this period). We examined the preoperative, intraoperative, and in-hospital periods, as well as the patients' status at the moment of the development of the clinical course of acute coronary syndrome, its structure and terms of manifestation, the dynamics of the coronary bed condition, also carrying out the analysis of treatment strategies and the in-hospital outcomes thereof. RESULTS: The development of acute coronary syndrome after coronary artery bypass grafting procedures was revealed in patients with a mean age of 58 (52; 63) years, with a history of postinfarction cardiosclerosis (70.37%), arterial hypertension (92.59%), dyslipidemia (51.83%), obesity (77.78%) and a multiple-vessel lesion of the coronary bed (67.90%) of intermediate risk according to the SYNTAX score estimated as an average of 26 (22; 32) points. In the structure of acute coronary syndrome having developed in patients with previously endured coronary artery bypass grafting operations, prevailing was its form of non-ST-segment elevation (87.65%), predominantly of a low risk (61.73%) which manifested itself averagely 24 (12; 35) months after the operation. The main factor of the development of acute coronary syndrome was progression of atherosclerosis (60.49%). The dominating strategy of treatment was medicamentous therapy (55.56%). The in-hospital mortality rate amounted to 2.47%. In the dynamics of the clinical status of the patients prior to coronary artery bypass grafting by the moment of the manifestation of acute cardiac ischaemia there took place a significant decrease in the left ventricular ejection fraction (p=0.01) and progression of atherosclerosis to the multifocal status (p=0.004). CONCLUSION: Patients with acute coronary syndrome, having previously endured coronary artery bypass grafting procedures appear to belong to a special cohort presenting with a series of clinical peculiarities and despite satisfactory in-hospital results do require special attention, with the development of appropriate algorithms for risk stratification and optimal therapeutic decision-making.

RESUMO

From 5 to 10% of patients presenting with acute coronary syndrome and receiving dual antiplatelet therapy require surgical myocardial revascularization. Dual antiplatelet therapy considerably increases the risk of surgical bleeding. Endoscopic harvesting of the great saphenous vein is a technique that can make it possible to decrease the injury and to minimize blood loss. The study included a total of 32 patients presenting with acute coronary syndrome and undergoing coronary artery bypass grafting. They were subdivided into two groups: Group One (study group) was composed of 17 patients subjected to endoscopic harvesting of the great saphenous vein in the flap. Group Two (comparison group) consisted of 15 patients undergoing an open technique of harvesting of the vein in the flap. During the entire perioperative period, the amount of discharge through drainages from the mediastinum did not differ significantly (958±173 ml for Group One patients and 1005±165 ml for Group Two patients, p=0.47). The amount of discharge from the bed of the great saphenous vein on the lower extremities in Group One patients turned out to be less than in Group Two patients (443±37 ml vs. 570±77 ml, p=0.04). A higher haemoglobin content in the total blood count was observed in the postoperative period in the Study Group patients (90±30 g/l vs. 74±21 g/l, respectively, p=0.03). The necessity to use donor blood preparations in Group One patients turned out to be less (transfusion of erythrocytic mass 0 and 2 (0; 2) doses, p=0.001; fresh frozen plasma 2 (0; 3) and 5 (3; 8) doses, respectively, p=0.0001). The duration of hospital stay amounted to 8±1.1 days in the study group and to 15±4.5 days in the comparison group (p<0.0001). Hence, this approach makes it possible to control blood loss in high-risk patients undergoing coronary artery bypass grafting on the background of dual antiplatelet therapy, to decrease the amount of donor blood, and to reduce the length of hospital stay.
