Effect of Pericardial Effusion Complicating ST-Elevation Myocardial Infarction as Predictor of Extensive Myocardial Damage and Prognosis. Am J Cardiol 2015; 116:1010-6. [PMID: 26235929 DOI: 10.1016/j.amjcard.2015.07.007] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2015] [Revised: 07/03/2015] [Accepted: 07/03/2015] [Indexed: 11/24/2022]
Abstract
Pericardial effusion (PE) is a common complication following ST-elevation myocardial infarction (STEMI). However, the frequency and prognostic relevance of PE complicating STEMI are unknown. Aim of this study was to investigate the exact incidence, infarct characteristics, and the prognostic impact of moderate-to-large PEs detected by cardiac magnetic resonance (CMR) in patients with acute reperfused STEMI. In total, 780 patients with STEMI reperfused by angioplasty (<12 hours after symptom onset) were enrolled in this CMR study at 8 centers. CMR was completed in median 3 days after infarction using a standardized protocol. Central core laboratory-masked analysis for the presence of moderate-to-large PE was performed. The primary clinical end point was the occurrence of major adverse cardiac events (MACE) defined as composite of all-cause death, reinfarction, and new congestive heart failure within 12 months after the index event. A moderate-to-large PE was detected in 183 patients (24%). Patients with moderate-to-large PEs had significantly larger infarcts, less myocardial salvage, a larger extent of microvascular obstruction, higher incidence of intramyocardial hemorrhage, and more pronounced left ventricular dysfunction (p <0.001 for all). Significant predictors of a moderate-to-large PE were age, Thrombolysis in Myocardial Infarction flow before percutaneous coronary intervention, and infarct size. MACE rates were significantly higher in the PE group (p = 0.003) and a moderate-to-large PE was identified as a significant independent predictor for MACE (hazard ratio 3.12, 95% confidence interval 1.49 to 6.81; p = 0.003) together with Thrombolysis in Myocardial Infarction risk score and left ventricular ejection fraction. In conclusion, a moderate-to-large PE complicating STEMI is a common finding (almost 25%) and related to more severe infarcts with subsequent significantly increased MACE rates during 1-year follow-up. Consequently, a moderate-to-large PE is a marker of poor outcome in patients with STEMI.

Abstract
BACKGROUND Quantitative assessment of microvascular injury is possible in patients with reperfused anterior myocardial infarction by invasive method. Coronary flow velocity patterns can also be assessed by transthoracic color Doppler echocardiography (TTCDE). OBJECTIVES The purpose of this study was to determine whether the coronary flow velocity pattern assessed by TTCDE serves as a predictor of adverse cardiac events and left ventricular remodeling. METHODS The study population consisted of 64 consecutive patients. We could analyze coronary flow velocity patterns by TTCDE in 59 of 64 patients (92%) after coronary intervention. The patients were followed up for the occurrence of complications and underwent serial measurement of left ventricular volumes. RESULTS In patients with a short deceleration time of diastolic flow velocity, the frequency of adverse cardiac events and left ventricular remodeling was higher. CONCLUSION It is possible to predict clinical outcome by assessing coronary flow velocity pattern by TTCDE.

Abstract
BACKGROUND Recently, it was reported that the degree of microvascular injury and left ventricular functional recovery during the chronic period can be predicted after treatment of the infarct-related artery based on the coronary flow velocity (CFV) pattern assessed using a Doppler guidewire. The aim of this prospective study was to examine whether the CFV pattern may predict complications and in-hospital survival after acute myocardial infarction (AMI). METHODS AND RESULTS The study population consisted of 169 consecutive patients with a first anterior AMI successfully treated with percutaneous coronary intervention (PCI). We examined the CFV pattern immediately after PCI using a Doppler guidewire. In accordance with previous findings, we defined severe microvascular injury as a diastolic deceleration time < or =600 ms and the presence of systolic flow reversal. Patients were divided into two groups: those without severe microvascular injury (n=118; group 1) and those with severe microvascular injury (n=51; group 2). All of the patients who had cardiac rupture were in group 2. Congestive heart failure (CHF) was observed more frequently in group 2 than in group 1 (53% versus 8%, P<0.001). The in-hospital cardiac mortality rate was significantly higher in group 2 than in group 1 (18% versus 0%, P<0.001). Nine patients in group 2 died, 5 patients because of CHF and 4 patients because of cardiac rupture. CONCLUSIONS These findings suggest that the CFV pattern is an accurate predictor of the presence or absence of complications and of in-hospital survival after AMI.

Abstract
BACKGROUND Left ventricular free wall rupture (FWR) usually develops within the first days of acute myocardial infarction (AMI) without warning, but it is uncertain whether a mild pericardial effusion might herald this complication. METHODS A 2-dimensional echocardiogram (2DE) was performed in patients with first AMI with (1149) or without (324) ST-segment elevation within 2 days. A second 2DE was performed 2 to 4 days later in 300 patients, 100 with and 200 without an initial mild PE (3-9 mm), and in those with initial moderate-severe PE (> or =10 mm) (MSPE) or who developed hypotension or died. RESULTS The first 2DE showed mild PE in 177 patients and MSPE in 51 patients, whereas a late (>2 days) MSPE occurred in 27 with a second routine 2DE, 15 (15%) with and 12 (6%) without initial mild PE (P =.01). Fourteen additional patients, 5 of 77 (6%) with and 9 of 1045 (1%) without initial PE, presented with hypotension and late MSPE (P <.002). Of 92 patients with MSPE, 90 had ST-segment elevation (98%), 60 had tamponade (65%), and 38 died of FWR or were operated on (41%). Results of pericardiocentesis performed in 64 patients were positive in 58, with hemopericardium in 57 (98%). Multivariant analysis showed mild PE on first 2DE and age of >60 years as the only independent predictors of late MSPE or late tamponade. CONCLUSIONS Mild PE within the first 2 days in patients aged >60 years with a first ST-segment elevation AMI is associated with an increased risk of late MSPE. Moreover, in this setting MSPE is most frequently associated with hemopericardium, and two thirds of these patients may develop tamponade/FWR.

Abstract
STUDY OBJECTIVE To assess the effect of coronary flow to the infarct zone before primary coronary angioplasty on hospital complications in patients with acute myocardial infarction (MI). DESIGN Consecutive case series analysis. SETTING Coronary-care unit in a university hospital. PATIENTS Two hundred sixty-four consecutive patients with ST-elevation acute MIs who had successful primary percutaneous transluminal coronary angioplasty. INTERVENTIONS Coronary angiography on hospital admission and serial echocardiography. MEASUREMENTS AND RESULTS The status of infarct-related artery flow before primary angioplasty was evaluated on hospital admission. Left ventricular wall motion and pericardial effusions were studied by echocardiography. One hundred ninety patients had total occlusions (Thrombolysis in Myocardial Infarction [TIMI] flow grade, 0 to 1) in the infarct-related artery (group 1), and 74 patients had antegrade flow (TIMI flow grade, 2 to 3) [group 2] before undergoing primary angioplasty procedures. When group 1 was subdivided into two groups (for the presence and absence of collateral flow), the patients with total occlusions and no collateral flow had a higher incidence of left ventricular aneurysmal wall motion (11% vs 1%, respectively; p = 0.03) and pericardial friction rub (15% vs 3%, respectively; p = 0.03) than did those in group 2. Moreover, those patients with total occlusions and no collateral flow had higher incidences of pericardial effusion (34% vs 17%, respectively; p = 0.02; and 34% vs 9%, respectively; p < 0.01) and in-hospital mortality (8% vs 1%, respectively; p = 0.04; and 8% vs 1%, respectively; p = 0.06) than did those patients in the other two groups. CONCLUSIONS Despite successful primary angioplasty, the absence of antegrade flow in the infarct-related artery and collateral flow to the infarct zone before angioplasty resulted in a higher incidence of in-hospital complications.

Abstract
Pericarditis is a common complication of acute myocardial infarction (MI). Its incidence during the first few days after acute MI is 24%-43% when echocardiographic criteria are used, whereas the frequency of clinical pericarditis is much less (from 5% for all acute MIs to 21% for anterior Q wave MIs). Clinical, electrocardiographic findings are discussed. Effusions are mostly small, and the resolution is frequently slow, lasting 1-18 months. Tamponade is extremely rare in the absence of cardiac rupture. Q wave MIs (especially anterior) are more frequently accompanied by pericardial effusion. The prognostic significance of echocardiographically proved pericarditis is questionable.

Abstract
To evaluate the incidence and clinical significance of infarction-associated pericardial effusion in patients with successful primary percutaneous transluminal coronary angioplasty, we studied 214 consecutive patients with a first Q-wave acute myocardial infarction. Based on 9 clinical variables, multivariate analysis was performed to determine the important variables related to the occurrence of pericardial effusion. Pericardial effusion was detected by echocardiography in 45 patients (21%); pericardial rub (p <0.001), number of advanced asynergic segments (p <0.001), ventricular aneurysmal motion (p = 0.03), and pulmonary capillary wedge pressure (p = 0.04) were found to be the important variables related to pericardial effusion. Among 45 patients with pericardial effusion, 29 patients with no pericardial rub had significantly higher pulmonary capillary wedge pressure than those with pericardial rub, whereas 16 patients with pericardial rub had a higher incidence of angiographic no reflow and ventricular aneurysmal motion than those without pericardial rub. Patients with pericardial effusion and a pericardial rub had a higher mortality rate than those without pericardial effusion (19% vs 3%; p = 0.02). Thus, pericardial effusion is still a relatively common clinical finding after primary percutaneous transluminal coronary angioplasty, and those with pericardial effusion and a pericardial rub were associated with more severe transmural myocardial damage and higher in-hospital mortality.

Abstract
The use of cardiac ultrasonography in the emergency department currently has two primary indications: determining the presence of cardiac tamponade and determining cardiac activity in patients with apparent pulselessness. Physicians are able to recognize both conditions after appropriate, but not overextensive, training sessions. The evaluation of penetrating trauma, acute myocardial infarction, and severe shock of uncertain origin require a higher degree of training and experience. All of these conditions are discussed in this article.

Abstract
Anomalous origin of the left coronary artery from the pulmonary artery most commonly presents in infancy with clinical features of dilated cardiomyopathy, congestive heart failure or cardiogenic shock as a result of myocardial ischemia. We report the first presentation of this disorder with hemorrhagic pericardial effusion and cardiac tamponade as a result of a transmural myocardial infarction. The list of other causes of hemorrhagic pericardial effusion must now include anomalous left coronary artery syndrome.

Abstract
STUDY OBJECTIVE This study investigated the long-term course of infarct-related pericarditis and pericardial effusion. Focus was given to the following issues: incidence and timing of pericarditis and pericardial effusion during the acute phase and 3 years follow-up, size, hemodynamic and clinical consequences of effusions, and potential risk of thrombolytic or anticoagulant therapy in patients with pericardial effusion. PATIENTS AND STUDY DESIGN Serial echocardiographic examinations were performed in 192 consecutive patients with first myocardial infarction during the acute phase (day 1, 5, 10, 21) and during 3 years' follow-up (year 1, 2, and 3 after infarction). The follow-up was 100%. Clinical, angiographic, and autopsy data were analyzed. RESULTS Pericardial effusion was detected at least once during serial echocardiographic examinations in 82 of 192 patients (43%). The incidence in different subgroups (with or without thrombolysis, open or closed artery at 3 weeks, infarction in left anterior descending, left circumflex, or right coronary artery perfusion bed) was similar. Most (48%) effusions were first detected on the fifth day, and most (50%) disappeared between days 21 and 365. However, in nine patients, the effusion persisted beyond 1 year (up to 3 years in three patients). Only systolic separation of pericardial layers was detected in 59% of effusions, circular effusion in 3.6% of all effusions. No cardiac tamponade developed. Heart failure or death complicated 49% of infarctions with pericardial involvement and 16% of infarctions without effusion (p < 0.01). Mortality alone was 8% among patients without effusion and 15% among those with more than minimal effusion (not significant). CONCLUSIONS Pericardial effusion can be detected by serial echocardiographic examinations in 43% of myocardial infarctions. It appears during the initial 5 days and disappears slowly during several weeks to several months. Anticoagulant and thrombolytic therapy does not increase the frequency or the size of effusions.

Abstract
To assess the clinical significance of pericardial effusion in Q-wave inferior wall acute myocardial infarction, 185 consecutive patients were examined by means of electrocardiogram, echocardiogram and hemodynamic monitoring. A pericardial effusion was present in 44 patients and was absent in 141 patients. Electrocardiographic right ventricular infarction (> or = 1 mm of ST-segment elevation and Q wave in V4R) was detected in 54 patients, with 20 patients having pericardial effusion. Patients with pericardial effusion had significantly more left ventricular segments with advanced asynergy, lower cardiac output, higher pulmonary artery wedge pressure and higher incidence of right ventricular infarction than those without pericardial effusion. There were 17 in-hospital deaths. Although there was no significant difference in the mortality rate between patients with and without right ventricular infarction, a significantly higher hospital mortality rate was observed in patients with pericardial effusion compared to those without it (23 vs 5%). Pericardial effusion was selected with age and pulmonary artery wedge pressure as important variables associated with hospital mortality by the discriminant analysis. Patients who developed pericardial effusion, regardless of right ventricular infarction, had more extensive myocardial damage, and hence, pericardial effusion was one of the predictors of increased hospital mortality.

Abstract
To elucidate the incidence and clinical factors related to the occurrence of pericardial effusion in infarction-associated pericarditis, 303 consecutive patients with their first Q-wave anterior myocardial infarction were examined carefully by means of auscultation, echocardiography, chest radiography, and hemodynamic monitoring. During the first 3 days, a pericardial rub was detected in 65 patients and was absent in 238 patients. Among the 65 patients with pericardial rub, pericardial effusion was present in 27 patients (group 1) and was absent in 38 patients (group 2). Although there were no significant differences in cardiac output, pulmonary artery wedge pressure and right atrial pressure between the two groups, patients in group 1 had significantly more left ventricular segments with advanced asynergy and higher radiographic scores (diffuse interstitial infiltrate or alveolar infiltrate) compared with those in group 2. Thus, pericardial effusion and increased extravascular lung water in infarction-associated pericarditis were not caused by left ventricular failure but by other mechanisms reflecting a larger infarct.

Abstract
To elucidate the effect of pericardial effusion on pulmonary gas exchange in patients with infarction-associated pericardial effusion, 294 consecutive patients with their first Q-wave anterior wall acute myocardial infarction were examined carefully by echocardiography, chest radiography and hemodynamic monitoring. A pericardial effusion was detected in 77 patients and was absent in 217 (group 1). Of the 77 patients with pericardial effusion, it was mild in 57 (group 2) and moderate in 20 (group 3). Patients with pericardial effusion (groups 2 and 3) had significantly greater pulmonary artery wedge pressure and more left ventricular segments with advanced asynergy than did those in group 1. Although there were no significant differences in pulmonary artery wedge pressure and number of left ventricular segments with advanced asynergy between groups 2 and 3, group 3 had significantly greater right atrial pressure, alveolar arterial oxygen difference and incidence of high radiographic score. Thus, accumulation of pericardial effusion to a moderate amount may contribute to the greater incidence of increase in extravascular lung water, and disturbance of pulmonary gas exchange.

Abstract
How can the suspicion of myocardial ischemia be confirmed without putting the patient through an invasive procedure? In patients who have had myocardial infarction, how can those at risk for pump failure and other complications and future cardiac events be identified? How are such complications detected? The answer to all these questions is echocardiography. The authors review how to use the technique and provide illustrative images.

Abstract
In a 49-year-old male with fever, dyspnea, and chest pain, thoracic x-ray revealed pneumonia with enlarged heart silhouette. Antibiotics were successful, pneumonia healed and complaints disappeared. Yet, during the following 3 months, echocardiography showed mild persistent pericardial effusion while in ECG both sinus tachycardia and ST-T changes were found suggesting chronic pericarditis. Magnetic resonance imaging, however, revealed an extensive posterobasal aneurysm with pericardial effusion substantiated by ventriculography. Coronary angiography showed diffuse three-vessel disease. Surgery revealed aneurysm with distinct perforation of the left ventricle and pericardial thrombi, thus aneurysmectomy as well as bypass grafts were performed. One year postoperatively, magnetic resonance imaging confirmed the absence of aneurysm with only a small irreversible posterobasal perfusion defect remaining as shown by thallium scintigraphy.

Abstract
To elucidate the clinical characteristics associated with regional ventricular dilatation in the early phase of myocardial infarction (MI), 228 patients with acute Q-wave anterior MI were studied. Forty-nine patients (21 percent) had echocardiographically demonstrated regional ventricular dilatation (an abnormal bulge in the left ventricular contour during both systole and diastole) on the third hospital day. Careful auscultation revealed that a pericardial rub was present in 49 patients (21 patients with and 28 patients without regional ventricular dilatation) during the first three days after hospital admission. Multivariate analysis was performed to determine the relative importance of pericardial rub with six other clinical variables related to regional ventricular dilatation. Pericardial rub and cardiac output were the significant factors related to the presence of regional ventricular dilatation. Thus, a pericardial rub, in concert with impaired left ventricular function, is a physical sign associated with regional ventricular dilatation, and anatomically transmural infarction is the possible factor explaining their association.

Abstract
To elucidate the role of inflammatory and hemodynamic factors in the genesis of atrial fibrillation in acute myocardial infarction, 228 patients with a first Q wave anterior myocardial infarction were studied. Forty-nine patients had pericarditis (detection of pericardial rub by careful auscultation), and 36 patients had echocardiographically demonstrated hydropericardium (presence of pericardial effusion without pericardial rub). During the first 3 days after admission, transient episodes of atrial fibrillation were observed in 10 patients (20%) with pericarditis (group 1), 15 patients (42%) with hydropericardium (group 2), and 20 patients (14%) without pericarditis and hydropericardium (group 3). Although there was no significant difference in the incidence of atrial fibrillation between groups 1 and 3, patients in group 2 had a significantly higher incidence of atrial fibrillation than those in groups 1 and 3. Pulmonary capillary wedge pressure and the number of advanced asynergic segments were found to be the important factors discriminating the three groups by multivariate analysis. Therefore atrial fibrillation after acute Q wave anterior infarction was not related to the inflammatory infiltration involving the atria but to the increase in atrial pressure resulting from hemodynamic change caused by more extensive myocardial damage.

Abstract
The effect of thrombolytic therapy on the frequency, time course and sequelae of pericardial effusion after myocardial infarction are unknown. A prospective, serial, 2-dimensional echocardiographic study of patients with myocardial infarction who received recombinant tissue-type plasminogen activator (rt-PA) was undertaken to address this issue. The study population comprised 52 of the 112 patients enrolled in the first Thrombolysis and Angioplasty in Myocardial Infarction trial at Duke University Medical Center. Enrollment in the serial echocardiography protocol was determined by equipment and support staff availability. Complete echocardiographic studies were performed within 90 minutes after initiation of thrombolytic therapy (day 0), and on days 1, 3 and 6. Patients undergoing serial echocardiography did not differ in demographic or clinical characteristics from those who did not. Pericardial effusion was present in 3 of 38 patients (8%) at day 0, in 2 of 44 (5%) at day 1, in 8 of 43 (19%) at day 3, and in 10 of 42 (24%) at day 6. By day 6, 3 of 10 pericardial effusions were moderate in size, 1 of 10 was large and the remainder were small. No patients developed echocardiographic or hemodynamic signs of cardiac tamponade. The prevalence and time course of pericardial effusion among patients with acute myocardial infarction who received rt-PA in this study are similar to observations reported in earlier studies in which patients did not receive thrombolytic therapy. Adverse sequelae of pericardial effusion after thrombolytic therapy are rare.

Abstract
To elucidate the clinical characteristics associated with pericardial effusion in the early phase of myocardial infarction, 330 patients with acute Q wave infarction were studied. According to echocardiography, 83 patients had pericardial effusion on the third day of hospitalization, and careful auscultation revealed that a pericardial rub was absent in 45 patients and was present in 38 patients. Based on seven clinical variables, multivariate analysis was performed to determine the important variables related to the occurrence of pericardial effusion with and without pericardial rub. Pulmonary capillary wedge pressure and left ventricular segments with advanced asynergy were the significant factors related to the occurrence of pericardial effusion without a pericardial rub. The presence of ventricular aneurysmal motion, left ventricular segments with advanced asynergy, and alveolar arterial oxygen difference were related to pericardial effusion with a pericardial rub. Therefore, a hemodynamic factor was the major mechanism associated with the increase in extravascular myocardial fluid and the consequent occurrence of hydropericardia in the absence of a pericardial rub, whereas an increase in the microvascular permeability in the myocardium with excessive fluid exudating through the irritated epicardial surface was the mechanism related to pericardial effusion with a pericardial rub in the early phase of acute myocardial infarction.

Abstract
The incidence and significance of pericardial effusions early in acute myocardial infarction remain unclear. Using two-dimensional echocardiography, 172 patients with an acute myocardial infarction were evaluated within 72 h of presentation. Thirty patients (17%) had a pericardial effusion (29 small, 1 moderate) while 142 (83%) did not. No patient developed cardiac tamponade or required pericardiocentesis. Patients with pericardial effusions had higher peak creatine kinase as compared to patients without effusions (2036 +/- 1466 vs. 1483 +/- 1241, p less than 0.05) and a greater number of aneurysms (20% vs. 6%, p less than 0.05). In-hospital mortality was higher in the patients with pericardial effusions (10% vs. 2%, p less than 0.05). In conclusion, pericardial effusions are common in the early AMI period but are generally small and hemodynamically insignificant. They are associated with larger infarcts and greater mortality.

Abstract
Post-myocardial infarction pericarditis can be confused with other conditions, including recurrent myocardial ischemia. The decline in the incidence of this type of pericarditis is thought by some to be linked to the decreasing use of anticoagulants in the treatment of myocardial infarction.

Abstract
Echocardiographic techniques are becoming more widespread for evaluating patients with known or suspected coronary artery disease. Because it affords an excellent overall view of the heart, two-dimensional echocardiography, rather than M-mode echocardiography, is the imaging procedure of choice when dealing with coronary artery disease. This technique can be used to make the initial diagnosis of acute myocardial infarction, diagnose complications, and assess prognosis following myocardial infarction. Additionally by combining this test with stress testing, latent coronary artery disease can be detected. Recovery of wall motion can be assessed following interventions such as thrombolysis or balloon angioplasty. Investigational and future uses include tissue characterization, which may allow detection of ischemic but potentially viable myocardium, direct coronary visualization for detection of atherosclerotic involvement of the proximal coronary arteries and myocardial contrast echocardiography. The latter technique allows visualization of perfusion by way of injecting contrast material into the coronary circulation. This has been demonstrated to be an accurate means of determining myocardial infarction size in an animal model and is currently being used in a number of centers in patients at the time of cardiac catheterization. In summary two-dimensional echocardiography currently allows assessment of patients with myocardial infarction from the time of their presentation through their convalescent period with respect to diagnosis, prognosis and presence of complications. Exercise echocardiography can diagnose latent coronary artery disease. The newer investigational techniques show promise for furthering our ability to evaluate patients with coronary artery disease using echocardiography.
