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: The study was aimed at comparatively assessing the immediate results of coronary artery bypass grafting operations without artificial circulation performed in non-ST-segment elevation acute myocardial infarction and chronic ischaemic heart disease. PATIENTS AND METHODS: The main group with non-ST-segment elevation acute myocardial infarction enrolled a total of 101 patients undergoing coronary artery bypass grafting without artificial circulation. The patients' age varied from 47 to 87 years, median 66.0 years (60.0; 71.0). The indication for the operation was persistent myocardial ischaemia on the background of carried out therapy with impossibility of performing percutaneous coronary intervention due to anatomy of coronary arteries and peculiarities of their pathology. The comparison group of chronic ischaemic heart disease was composed of 108 patients undergoing elective coronary artery bypass grafting without artificial circulation. The patients' age varied from 40 to 92 years, median - 60.0 years (58.0; 68.0). The patients with acute myocardial infarction had a significantly greater (p<0.05) number of coronary arteries measuring in diameter 2.5 mm and more, with significant occlusive and stenotic lesions, as well as a higher total SYNTAX score. The patients undergoing elective surgery were found to have an initially higher (p<0.05) left ventricular ejection fraction. RESULTS: In the group of acute myocardial infarction the waiting times for coronary artery bypass grafting varied from 2 to 8 days, median of waiting - 4.0 days (4.0; 5.0). The lethality rate (p<0.05) in the group of acute myocardial infarction amounted to 3.0% (3 cases) and in the group of chronic ischaemic heart disease to 0.9% (1 case). Twenty-one (20.8%) operations were carried out within the first 72 hours, with eighty surgical interventions (79.2%) performed after 72 hours from the onset of the disease. All 3 (3.8%) lethal outcomes were observed after coronary artery bypass grafting procedures performed later than 72 hours from the onset of acute myocardial infarction (p>0.05). The total number of complications (p>0.05) amounted to 18 (17.8%) and 10 (9.3%) in the group of acute myocardial infarction and in the group of chronic ischaemic heart disease, respectively. CONCLUSION: The immediate results of delayed coronary artery bypass grafting procedures without artificial circulation for acute myocardial infarction and chronic ischaemic heart disease were statistically comparable (p>0.05) by the lethality and complication rates. Lethality in the group of non-ST-segment elevation acute myocardial infarction din not depend on the time of operation after the onset of the disease.

RESUMO

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is an increasingly recognised condition and it accounts for approximately 10% of all cases of MI. Despite the absence of obstructive coronary artery disease, patients with MINOCA are at increased risk of morbidity and mortality compared to the general population. While many well recognised conditions can present as MINOCA, it can be difficult to reach a final diagnosis with certainty due to the relative infrequency of these conditions in the general population and the lack of diagnostic gold-standard tests. The most common causes of MINOCA are myocarditis, coronary vasospasm, coronary plaque disruption and coronary thrombus or embolism. These can be assessed by way of cardiac magnetic resonance imaging, intra-coronary imaging modalities and clinically relevant diagnostic blood tests, respectively. There are less common and rarer aetiologies which should be considered in the absence of an apparent cause, each with a unique diagnostic standard. By following a systematic approach of diagnostic tests, an underlying cause of MINOCA can be found in the majority of cases, allowing a directed management strategy to be pursued.

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

INTRODUCTION: Influenza may precipitate cardiovascular disease, but influenza typically peaks in winter, coinciding with other triggers of myocardial infarction (MI) such as low air temperature, high wind velocity, low atmospheric pressure, and short sunshine duration. OBJECTIVE: We aimed to determine the relationship of week-to-week variation in influenza cases and acute MI, controlling for meteorological factors in a nationwide population. METHODS: Weekly laboratory-confirmed influenza case reports were obtained from the Public Health Agency of Sweden from 2009 to 2016 and merged with the nationwide SWEDEHEART MI registry. Weekly incidence of MI was studied with regard to number of influenza cases stratified into tertiles of 0-16, 17-164, and >164 cases/week. Incidence rate ratios (IRR) were calculated using a count regression model for each category and compared to a non-influenza period as reference, controlling for air temperature, atmospheric pressure, wind velocity, and sunshine duration. RESULTS: A total of 133562 MI events was reported to the registry during the study period. Weeks with influenza cases were associated with higher incidence of MI than those without in unadjusted analysis for overall MI, ST-elevation MI and non ST-elevation MI independently. During the influenza season, weeks with 0-16 reported cases/week were not associated with MI incidence after adjusting for weather parameters, adjusted IRR for MI was 1.03 (95% CI 1.00-1.06, P = 0.09). However, weeks with more cases reported were associated with MI incidence: 17-163 reported cases/week, adjusted IRR = 1.05 (95% CI 1.02-1.08, P = 0.003); and for ≥164 cases/week, the IRR = 1.06 (95% CI 1.02-1.09, P = 0.002). Results were consistent across a large range of subgroups. CONCLUSIONS: In this nationwide observational study, we found an association of incidence of MI with incidence of influenza cases beyond what could be explained by meteorological factors.

RESUMO

BACKGROUND AND PURPOSE: Rates of depression after ischemic stroke (IS) and myocardial infarction (MI) are significantly higher than in the general population and associated with morbidity and mortality. There is a lack of nationally representative data comparing depression and suicide attempt (SA) after these distinct ischemic vascular events. METHODS: The 2013 Nationwide Readmissions Database contains >14 million US admissions for all payers and the uninsured. Using International Classification of Disease, 9th Revision, Clinical Modification Codes, we identified index admission with IS (n = 434,495) or MI (n = 539,550) and readmission for depression or SA. We calculated weighted frequencies of readmission. We performed adjusted Cox regression to calculate hazard ratio (HR) for readmission for depression and SA up to 1 year following IS versus MI. Analyses were stratified by discharge home versus elsewhere. RESULTS: Weighted depression readmission rates were higher at 30, 60, and 90 days in patients with IS versus MI (0.04%, 0.09%, 0.12% vs. 0.03%, 0.05%, 0.07%, respectively). There was no significant difference in SA readmissions between groups. The adjusted HR for readmission due to depression was 1.49 for IS versus MI (95% CI 1.25-1.79, p < 0.0001). History of depression (HR 3.70 [3.07-4.46]), alcoholism (2.04 [1.34-3.09]), and smoking (1.38 [1.15-1.64]) were associated with increased risk of depression readmission. Age >70 years (0.46 [0.37-0.56]) and discharge home (0.69 [0.57-0.83]) were associated with reduced hazards of readmission due to depression. CONCLUSIONS: IS was associated with greater hazard of readmission due to depression compared to MI. Patients with a history of depression, smoking, and alcoholism were more likely to be readmitted with depression, while advanced age and discharge home were protective. It is unclear to what extent differences in type of ischemic tissue damage and disability contribute, and further investigation is warranted.

RESUMO

Importance: Perioperative cardiovascular complications occur in 3% of hospitalizations for noncardiac surgery in the US. This review summarizes evidence regarding cardiovascular risk assessment prior to noncardiac surgery. Observations: Preoperative cardiovascular risk assessment requires a focused history and physical examination to identify signs and symptoms of ischemic heart disease, heart failure, and severe valvular disease. Risk calculators, such as the Revised Cardiac Risk Index, identify individuals with low risk (<1%) and higher risk (≥1%) for perioperative major adverse cardiovascular events during the surgical hospital admission or within 30 days of surgery. Cardiovascular testing is rarely indicated in patients at low risk for major adverse cardiovascular events. Stress testing may be considered in patients at higher risk (determined by the inability to climb ≥2 flights of stairs, which is <4 metabolic equivalent tasks) if the results from the testing would change the perioperative medical, anesthesia, or surgical approaches. Routine coronary revascularization does not reduce perioperative risk and should not be performed without specific indications independent of planned surgery. Routine perioperative use of low-dose aspirin (100 mg/d) does not decrease cardiovascular events but does increase surgical bleeding. Statins are associated with fewer postoperative cardiovascular complications and lower mortality (1.8% vs 2.3% without statin use; P < .001) in observational studies, and should be considered preoperatively in patients with atherosclerotic cardiovascular disease undergoing vascular surgery. High-dose ß-blockers (eg, 100 mg of metoprolol succinate) administered 2 to 4 hours prior to surgery are associated with a higher risk of stroke (1.0% vs 0.5% without ß-blocker use; P = .005) and mortality (3.1% vs 2.3% without ß-blocker use; P = .03) and should not be routinely used. There is a greater risk of perioperative myocardial infarction and major adverse cardiovascular events in adults aged 75 years or older (9.5% vs 4.8% for younger adults; P < .001) and in patients with coronary stents (8.9% vs 1.5% for those without stents; P < .001) and these patients warrant careful preoperative consideration. Conclusions and Relevance: Comprehensive history, physical examination, and assessment of functional capacity during daily life should be performed prior to noncardiac surgery to assess cardiovascular risk. Cardiovascular testing is rarely indicated in patients with a low risk of major adverse cardiovascular events, but may be useful in patients with poor functional capacity (<4 metabolic equivalent tasks) undergoing high-risk surgery if test results would change therapy independent of the planned surgery. Perioperative medical therapy should be prescribed based on patient-specific risk.

RESUMO

Since early 2020, the world has been facing a pandemic caused by the novel coronavirus SARS-CoV-2. Although this positive single-stranded RNA virus primarily causes pulmonary infection and failure, it has been associated with multiple cardiovascular diseases including troponin elevation, myocarditis, and cardiac arrhythmias. Cardiac patients are susceptible to developing more severe infection from SARS-COV-2, making management complicated. In this review we discuss the cardiac manifestations of COVID-19 infections as well as considerations for the management of primary cardiac pathologies during this pandemic.

RESUMO

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a heterogeneous entity with an inflammatory etiopathogenesis. This study investigated the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) in patients with MINOCA. Coronary angiographies performed between June 2015 and August 2018 were analyzed retrospectively and included 72 patients with MINOCA and 248 controls with normal coronary angiograms. The predictors of mortality were determined by univariate Cox regression analysis. The mean age of the subjects was 46 ± 9 years, and 176 (55%) were female. Median follow-up was 21 (max: 42) months. Neutrophil-to-lymphocyte ratio was significantly higher in the MINOCA group than in the controls (P < .01). During long-term follow-up, the number of deaths was 6 in the MINOCA group and none in the control patients (P < .01). Univariate Cox regression analysis revealed that the NLR (hazard ratio: 1.24, 95% confidence interval: 1.09-1.41, P = .001) was a predictor of mortality in patients with MINOCA. Kaplan-Meier analysis also showed that patients with MINOCA had relatively higher mortality rate (long-rank test; P < .01). In conclusion, the NLR is significantly higher in patients with MINOCA compared with controls, and it is a predictor of long-term mortality.

RESUMO

AIMS: The usefulness of mortality statistics relies on the validity of death certificate diagnosis. However, diagnosing the causal sequence of conditions leading to death is not simple. We examined diagnostic support for fatal acute myocardial infarction (AMI) and investigated its association with regional variation. METHODS AND RESULTS: From Danish nationwide registers, we identified the study population (N = 3,244,051) of whom 36,669 individuals were recorded with AMI as the underlying cause-of-death between 2002 and 2015. We included clinical diagnoses, procedures, and claimed prescriptions related to atherosclerotic disease to evaluate the level of diagnostic support for fatal AMI in three diagnostic groups (Definite; Plausible; Uncertain). Adjusted mortality rates, rate ratios, and odds ratios were estimated for each AMI category, stratified by hospital region using multivariable regression models. More than one-third (N = 12,827, 35%) of deaths reported as fatal AMI had uncertain diagnostic support. The largest regional variation in AMI mortality rate ratios, varying from 1.16 (95%CI:1.02;1.31) to 1.62 (95%CI:1.43;1.83), was found among cases with uncertain diagnostic supportive data. Substantial inter-regional differences in the degree to which death occurs outside hospital [OR: 1.01 (95%CI:0.92;1.12) - 1.49 (95%CI:1.36;1.63)] and general practitioners determining the cause-of-death at home were present. Minor regional differences [OR: 0.96 (95%CI:0.85;1.07) - 1.16 (95%CI:1.04;1.29)] in in-hospital AMI mortality were observed. CONCLUSION: There is significant regional variation associated with recording AMI as a cause-of-death. This variation is predominately based on death certificate diagnoses without diagnostic supportive evidence. Studies of fatal AMI should include a stratification on supportive evidence of the diagnosis.

RESUMO

Acute myocardial infarction (MI) represents one of the most common hospital encounters, with significant short-term and long-term morbidity and mortality, and frequently occurs in patients with chronic kidney disease (CKD). Cardiac troponin is an exquisitely sensitive biomarker for myocardial injury and plays an essential role in the diagnosis, risk-stratification, and management of MI. In 2017, the United States Food and Drug Administration approved Roche Diagnostics' 5th generation high-sensitivity cardiac troponin (hs-cTn) for clinical use. Whilst the improved analytical sensitivity of these new high-sensitivity troponin assays facilitate early diagnosis of MI, it also frequently identifies troponin elevations above the conventional reference threshold in the context of non-coronary conditions such as renal dysfunction, and can represent a major diagnostic challenge to clinicians. Furthermore, the optimal management strategy of patients with troponin elevation and high comorbidity burden, a common issue in patients with CKD, remains undefined. In recent years, there has been substantial research and progress undertaken in this rapidly evolving area. In this review, we aim to provide clinicians with an overview of hs-cTn in the setting of CKD as well as an update on its application and the particular considerations involved in the management of myocardial infarction, stable coronary artery disease and myocardial injury in this high risk population.

RESUMO

BACKGROUND: Growing evidence suggests that under-diagnosis of acute myocardial infarction (AMI) may be common in sub-Saharan Africa. Prospective studies of routine AMI screening among patients presenting to emergency departments in sub-Saharan Africa are lacking. Our objective was to determine the prevalence of AMI among patients in a Tanzanian emergency department. METHODS: In a prospective observational study, consecutive adult patients presenting with chest pain or shortness of breath to a referral hospital emergency department in northern Tanzania were enrolled. Electrocardiogram (ECG) and troponin testing were performed for all participants to diagnose AMI types according to the Fourth Universal Definition. All ECGs were interpreted by two independent physician judges. ECGs suggesting ST-elevation myocardial infarction (STEMI) were further reviewed by additional judges. Mortality was assessed 30 days following enrollment. RESULTS: Of 681 enrolled participants, 152 (22.3%) had AMI, including 61 STEMIs and 91 non-STEMIS (NSTEMIs). Of AMI patients, 91 (59.9%) were male, mean (SD) age was 61.2 (18.5) years, and mean (SD) duration of symptoms prior to presentation was 6.6 (12.2) days. In the emergency department, 35 (23.0%) AMI patients received aspirin and none received thrombolytics. Of 150 (98.7%) AMI patients completing 30-day follow-up, 65 (43.3%) had died. CONCLUSIONS: In a northern Tanzanian emergency department, AMI is common, rarely treated with evidence-based therapies, and associated with high mortality. Interventions are needed to improve AMI diagnosis, care, and outcomes.

RESUMO

The unprecedented and rapidly spreading Coronavirus Disease-19 (COVID-19) pandemic has challenged public health care systems globally. Based on worldwide experience, India has initiated a nationwide lockdown to prevent the exponential surge of cases. During COVID-19, management of cardiovascular emergencies like acute Myocardial Infarction (MI) may be compromised. Cardiological Society of India (CSI) has ventured in this moment of crisis to evolve a consensus document for care of acute MI. However, this care should be individualized, based on local expertise and governmental advisories.

RESUMO

OBJECTIVES: We aimed to determine the level of awareness of myocardial infarction (MI) symptoms among the general public in Korea and identify factors affecting awareness of MI symptoms using data from the 2017 Korea Community Health Survey (KCHS). METHODS: This is a cross-sectional study using KCHS data. Based on five questions about MI symptoms, participants were divided into an awareness group (replied 'yes' to all five questions) and an unawareness group (replied 'no' or 'not sure' to at least one of five questions) for analysis. RESULTS: Of a total of 228,281 participants, 42.4% were aware of MI symptoms. There was a high level of awareness of chest pain and shortness of breath, but a low level of awareness of gastrointestinal symptoms and pain in the arm, shoulder, jaw, neck, and back. While women had a higher level of overall awareness relative to men, they showed a lower level of awareness regarding chest pain and discomfort. The factors affecting awareness of MI symptoms were gender, age, education level, occupation, smoking, drinking, physical inactivity, and cardiovascular disease risk factors. CONCLUSIONS: In order to enhance awareness of MI symptoms among the general population, appropriate education and promotion efforts must be implemented based on gender, age, education level, and occupation. Moreover, active efforts by the government, educational institutions, and medical institutions are necessary to improve awareness of both typical and atypical MI symptoms. Furthermore, health policies to promote reduced smoking and drinking and increased physical activity, as well as continuous monitoring and management of individuals with cardiovascular disease risk factors, are required.

RESUMO

BACKGROUND: Several studies have previously demonstrated that higher systolic blood pressure level means lower risk of adverse cardiovascular outcomes. However, there is a lack of further investigation into the nonlinear relationship between admission systolic blood pressure (SBP) and adverse outcomes of acute myocardial infarction (AMI) patients. OBJECTIVES: The aim of this study was to investigate the specific relationship between admission SBP and incidence of major adverse cardiovascular events (MACE) in 30 days for AMI patients. METHODS AND RESULTS: Using data from the ACS-QUIK trial, we analyzed 21,364 patients from Kerala, India. In univariate linear-regression model, the OR was 0.90 per 10mmHg, the confidence interval (CI) was 95% (0.87-0.92) and P < 0.0001. The generalized additive model (GAM) showed a nearly U-shaped curve between admission SBP and MACE. Using a two-piecewise linear regression model, we calculated an inflection point of 159 mmHg. We found that the higher admission SBP is associated with lower incidence of MACE of AMI patients. In addition, subgroups with different LVEF have distinct effects on blood pressure-related outcomes. Lower SBP has a greater risk when LVEF < 40%. CONCLUSION: The present study revealed the U-shaped relationship between admission SBP and the risk of adverse cardiovascular outcome. The admission SBP could be a marker to provide clinical assessment and treatment. TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov. Unique identifier: NCT02256657.

RESUMO

BACKGROUND: Cardiovascular disease is a serious complication in patients with dysglycaemia, defined as either type 2 diabetes or impaired glucose tolerance. Research focusing on the identification of potential markers for atherothrombotic disease in these subjects is warranted. The antiphospholipid syndrome is a common acquired prothrombotic condition, defined by a combination of thrombotic events and/or obstetric morbidity and positivity of specific antiphospholipid antibodies. Available information on antiphospholipid antibodies in dysglycaemia is scarce. OBJECTIVE: This study investigates the association between antiphospholipid antibodies and dysglycaemia. PATIENTS/METHODS: The PAROKRANK (periodontitis and its relation to coronary artery disease) study included 805 patients, investigated 6-10 weeks after a first myocardial infarction, and 805 matched controls. Participants without known diabetes (91%) underwent an oral glucose tolerance test. Associations between antiphospholipid antibodies (anti-cardiolipin and anti-ß2 glycoprotein-I IgG, IgM and IgA) and dysglycaemia were analysed. RESULTS: In total, 137 (9%) subjects had previously known type 2 diabetes and 371 (23%) newly diagnosed dysglycaemia. Compared with the normoglycaemic participants, those with dysglycaemia had a higher proportion with first myocardial infarction (61% vs 45%, p < 0.0001) and were more often antiphospholipid antibody IgG positive (8% vs 5%; p = 0.013). HbA1c, fasting glucose and 2-h glucose were significantly associated to antiphospholipid antibody IgG. Odds ratios (ORs) were 1.04 (95% confidence interval [CI] 1.02-1.06), 1.14 (95% CI 1.00 - 1.27) and 1.12 (95% CI 1.04 - 1.21), respectively, after adjustments for age, gender and smoking. CONCLUSIONS: This study reports an association between antiphospholipid antibody IgG positivity and dysglycaemia. Further studies are needed to verify these findings and to investigate if antithrombotic therapy reduces vascular complications in antiphospholipid antibody positive subjects with dysglycaemia.
