Usefulness of antithrombotic therapy in resting angina pectoris or non-Q-wave myocardial infarction in preventing death and myocardial infarction (a pilot study from the Antithrombotic Therapy in Acute Coronary Syndromes Study Group).

In a prospective pilot trial of antithrombotic therapy in the acute coronary syndromes (ATACS) of resting and unstable angina pectoris or non-Q-wave myocardial infarction, 3 different antithrombotic regimens in the prevention of recurrent ischemic events were compared for efficacy. Ninety-three patients were randomized to receive aspirin (325 mg/day), or full-dose heparin followed by warfarin, or the combination of aspirin (80 mg/day) plus heparin and then warfarin. Trial antithrombotic therapy was added to standardized antianginal medication and continued for 3 months or until an end point was reached. Analysis, by intention-to-treat, of the 3-month end points, revealed the following: recurrent ischemia occurred in 7 patients (22%) after aspirin, in 6 patients (25%) after heparin and warfarin, and in 16 patients (43%) after aspirin combined with heparin and then warfarin; coronary revascularization occurred in 12 patients (38%) after aspirin, in 12 patients (50%) after heparin and warfarin, and in 22 patients (60%) after aspirin combined with heparin and then warfarin; myocardial infarction occurred in 1 patient (3%) after aspirin, in 3 patients (13%) after heparin and warfarin, and in no patient after aspirin combined with heparin and then warfarin; no deaths occurred after aspirin or after aspirin combined with heparin and then warfarin, but 1 patient (4%) died after warfarin alone; major bleeding occurred in 3 patients (9%) after aspirin, in 2 patients (8%) after heparin and warfarin, and in 3 patients (8%) after aspirin combined with heparin and then warfarin. Recurrent myocardial ischemia occurred at 3 +/- 3 days after randomization.(ABSTRACT TRUNCATED AT 250 WORDS)

Assessment of global and regional left ventricular performance at rest and during exercise after thrombolytic therapy for acute myocardial infarction: results of the Thrombolysis in Myocardial Infarction (TIMI) II Study.

Global and regional left ventricular performances were evaluated with equilibrium radionuclide angiocardiography in patients in the Thrombolysis in Myocardial Infarction (TIMI) II trial at the time of hospital discharge. Studies at rest were available in 1,162 (69%) of the invasive and 1,150 (69%) of the conservative strategy patients, and exercise studies in 1,133 (67%) of the invasive and 1,145 (69%) of the conservative patients. Repeat studies were performed at the time of 6-week follow-up. Global and regional ejection fraction at rest were both comparable in patients assigned to each of the treatment strategies. However, at the time of hospital discharge patients in the invasive strategy had normal exercise responses more frequently (29.7 vs 25.8% p = 0.01), greater peak exercise LV ejection fraction (54.8 +/- 13.8% vs 53.1 +/- 14.1%, p = 0.004), greater exercise--rest change in LV ejection fraction (3.7 +/- 6.7% vs 2.7 +/- 7.2%, p less than 0.001) and greater peak exercise infarct zone regional ejection fraction (53.2 +/- 31.1% vs 50.3 +/- 33.0%, p less than 0.001) than patients assigned to the conservative strategy. At 6-week follow-up these differences between treatment strategies were no longer evident. When data were restricted to those collected at comparable work loads, similar differences in hospital discharge exercise performance between invasive vs conservative strategy patients were observed. Thus, there is a small transient difference in exercise global and regional LV performance associated with an invasive as opposed to conservative strategy after thrombolytic therapy. These differences are noted at the time of hospital discharge but not at 6 weeks, and are unlikely to confer clinical benefit.

Importance of a patent infarct-related artery for hospital and late survival after direct coronary angioplasty for acute myocardial infarction.

The importance of a patent infarct-related artery (IRA) for hospital and late survival was examined in 383 patients with acute myocardial infarction treated with direct coronary angioplasty. At hospital discharge, 317 of 348 patients (91%) had a patent IRA and mean follow-up left ventricular (LV) ejection fraction (EF) was 58%. Cardiac survival after hospital discharge at 1, 3 and 6 years was 99, 95 and 90%. Patency of the IRA was the most important determinant of hospital mortality: patent versus occluded IRA, 5 vs 39% mortality, p less than 0.001. Follow-up LVEF was the most important determinant of late cardiac mortality: follow-up LVEF greater than or equal to 45 versus less than 45%, 2 versus 24% mortality, p less than 0.001. Patency of the IRA was not a significant predictor of late cardiac mortality in the group as a whole: patent versus occluded IRA, 4.7 versus 6.5% mortality, p = 0.67. In the subgroup of patients with depressed initial LVEF less than 45%, patency was a significant predictor of late cardiac mortality: patent versus occluded IRA, 9.2 versus 40% mortality, p = 0.03. Patients with a patent IRA had better recovery of LV function than patients with an occluded IRA (follow-up LVEF 58.5 versus 47.6%, p less than 0.001). When late cardiac mortality was adjusted for differences in follow-up LVEF, patency was no longer a significant predictor of late mortality. Our results indicate patency of the IRA is the most important determinant of hospital survival, and LV function (measured after recovery) is the most important determinant of late cardiac survival.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparison of long-term outcome after acute myocardial infarction in patients never graduated from high school with that in more educated patients. Multicenter Investigation of the Limitation of Infarct Size (MILIS).

The clinical course of 363 patients with acute myocardial infarction who did not complete high school education was compared with that of 453 who completed at least high school. Both the in-hospital and 4-year mortality rates were markedly greater for the less educated than for the more educated patients (13 vs 5% [p < 0.001], and 36 vs 17% [p < 0.001]). Adverse baseline characteristics were partially responsible for the increased in-hospital (p = 0.059 after adjustment) and long-term (p = 0.024 after adjustment) mortality. The less educated patients were not as likely to quit smoking after acute myocardial infarction as were the more educated ones (38 vs 49%; p < 0.05). Patients who continued smoking had a greater mortality than did those who quit (24 vs 15% [p < 0.05] for less educated, and 10 vs 4% [p < 0.05] for better educated). Therefore, greater effort should be directed to smoking cessation among the high-risk group of less educated patients. However, the smoking continuation was responsible for only a small portion of the mortality difference, suggesting unidentified causes of mortality, such as lack of compliance with therapy and possible social isolation. Despite the high-risk status of the less educated patients, cardiac catheterization tended not to be performed as frequently as in the more educated patients after discharge from the hospital (16 vs 21%; p < 0.06 at 6 months).

Serum apolipoprotein levels in relation to acute myocardial infarction and its risk factors. Apolipoprotein A-I levels in male survivors of myocardial infarction.

The significance of high density lipoproteins in the etiology of clinical complications to atherosclerosis has recently received increased attention. The levels of the major apolipoprotein in high density lipoproteins, apoA-I, have been determined in patients who had had an acute myocardial infarction, and compared with a cholesterol-matched and a randomly selected control group. ApoA-I levels were lower in the patients than in the control groups. ApoA-I levels were also lower in smokers than in non-smokers. The difference between patients and control groups persisted even when the groups were stratified according to smoking habits. This suggests that low levels of apo-A-I as well as alphalipoprotein cholesterol are additional characteristics of the infarction patients, even when the established risk factors, smoking and hyperlipidemia are taken into account.

The Cincinnati Myocardial Infarction and Hormone Family Study: family resemblance for dehydroepiandrosterone sulfate in control and myocardial infarction families.

Dehydroepiandrosterone sulfate (DHEAS) was examined in random (control) and nonrandom (case) families participating in the Cincinnati Myocardial Infarction and Hormone (CIMIH) family study. The case families were ascertained through white men who survived a myocardial infarction (MI) before the age of 56, whereas control families were recruited through advertisements and through an adolescent boy maturation study. Both familial correlations and genetic effects of DHEAS were investigated. First, maximum likelihood estimates of the sex-specific familial correlations (corrected for nonrandom ascertainment) suggested that there was significant heterogeneity between the two sampling types. This heterogeneity was isolated to the male sibling correlation, which was higher in the case than control families. Post hoc analyses suggested that the sibling group heterogeneity may be in part a function of age, since the control sample offspring were on average much younger than those in case families. No sex differences other than those for the siblings were noted in the familial correlations. Second, heritability was investigated in control families using a simple path model (TAU) that allowed for sex differences. The only significant model parameter was the sex-specific familiarity (combined polygenic and familial environmental effects), which was larger in females (74%) than in males (29%). In general, these analyses suggested that (1) DHEAS may play only a limited role in the increased risk for premature MI, and (2) the degree of heritable (familial) variation may be dependent on sex.

Mismatch of left ventricular function and infarct size demonstrated by technetium-99m isonitrile imaging after reperfusion therapy for acute myocardial infarction: identification of myocardial stunning and hyperkinesia.

Quantitation of perfusion defect size using tomographic imaging with technetium-99m-hexakis-2-methoxy isobutyl isonitrile was performed at the time of hospital discharge in 32 patients with a first myocardial infarction who underwent successful coronary reperfusion within 8 h of the onset of chest pain. Reperfusion was accomplished with thrombolysis or primary coronary angioplasty. Radionuclide angiography was performed at discharge and 6 weeks later. There was a close correlation between perfusion defect size and values for ejection fraction and regional wall motion both at discharge (r = -0.80 and -0.75, respectively) and 6 weeks later (r = -0.81 and -0.81, respectively). There was no overall group difference in ejection fraction between the value at discharge and at 6 weeks; however, five patients had a significant increase (greater than or equal to 0.08) and six had a significant decrease (greater than or equal to 0.08) in ejection fraction. In patients with a significant increase at 6 weeks, ejection fraction was significantly lower at discharge than the value predicted from perfusion defect size (0.37 +/- 0.09 measured versus 0.47 +/- 0.13 predicted, p less than 0.05) and it improved at 6 weeks to near predicted values (0.51 +/- 0.07). In patients with a significant decrease at 6 weeks, ejection fraction was significantly higher at discharge than the value predicted from perfusion defect size (0.60 +/- 0.10 measured versus 0.50 +/- 0.10 predicted, p less than 0.05) and it decreased at 6 weeks to near predicted levels (0.51 +/- 0.09). Left ventricular ejection fraction at the time of hospital discharge is a potentially misleading index of the efficacy of reperfusion therapy for myocardial infarction. In a significant minority (34%) of patients this index does not accurately reflect perfusion defect size, apparently because of the effects of myocardial stunning and compensatory hyperkinesia.

Correlation between level of heparinization and patency of the infarct-related coronary artery after treatment of acute myocardial infarction with alteplase (rt-PA).

BACKGROUND AND OBJECTIVES: The conjunctive use of intravenous heparin may influence the efficacy of alteplase for coronary thrombolysis in patients with acute myocardial infarction. In this study we examined the relation between the level of intravenous anticoagulation with heparin and sustained coronary artery patency in a subgroup of patients of the European Cooperative Study Group (ECSG) trial. METHODS: In the ECSG trial, patients treated with alteplase and aspirin were randomized to concomitant fixed doses of intravenous heparin (a bolus dose of 5,000 U followed by a continuous infusion of 1,000 U/h or placebo). The current study group comprised 149 of 324 ECSG patients allocated to heparin therapy and 132 of 320 ECSG patients allocated to placebo administration who had both an interpretable coronary angiogram obtained within 6 days of treatment and sufficient plasma samples to assess the level of anticoagulation. Activated partial thromboplastin times, fibrinogen and D-dimer levels were determined on plasma samples at baseline and at 45 min and 3, 12, 24 and 36 h after the start of alteplase administration. RESULTS: The coronary artery patency rate was higher in patients allocated to heparin therapy than in those allocated to placebo (80% and 71%, respectively, p = 0.05). Patients allocated to heparin were classified into three subgroups: 48 patients (32%) with all activated partial thromboplastin times at least twice their own baseline value (optimal anticoagulation), 40 patients (27%) with the lowest activated partial thromboplastin time at 3, 12, 24 or 36 h between 130% and 200% of the baseline value (suboptimal anticoagulation) and 61 patients with at least one activated partial thromboplastin time less than 130% of baseline (inadequate anticoagulation). In the heparin group, coronary artery patency correlated with the level of anticoagulation: 90%, 80% and 72%, respectively, in patients with optimal, suboptimal and inadequate anticoagulation (p = 0.02, optimal vs. inadequate anticoagulation). Heparin administration was associated with a smaller reduction in fibrinogen and a smaller increase in D-dimer level during and after alteplase administration. No correlation was found between fibrinogen or D-dimer levels and coronary artery patency. No intracerebral hemorrhage occurred in these patients; however, bleeding was more frequent in the subgroup with optimal anticoagulation (p = 0.05). CONCLUSIONS: Intense anticoagulation with intravenous heparin enhances coronary artery patency after alteplase treatment of acute myocardial infarction.

Value of radionuclide rest and exercise left ventricular ejection fraction in assessing survival of patients after thrombolytic therapy for acute myocardial infarction: results of Thrombolysis in Myocardial Infarction (TIMI) phase II study. The TIMI Study Group.

OBJECTIVES: This study sought to determine the prognostic value of rest and exercise left ventricular ejection fraction in patients receiving thrombolytic therapy as part of the Thrombolysis in Myocardial Infarction (TIMI) trial. BACKGROUND: In the prethrombolytic era, ejection fraction at rest as well as during exercise was an important prognostic index in patients recovering from acute myocardial infarction. The prognostic value of these measurements in the thrombolytic era is not clear. METHODS: As part of the TIMI II protocol, we obtained radionuclide left ventricular ejection fraction at rest and during symptom-limited submaximal supine exercise. Measurements were related to 1-year all-cause as well as cardiac mortality. In addition, the relation between ejection fraction obtained at rest and 1-year cardiac mortality in this study was compared with the relation established previously in the prethrombolytic era by the Multicenter Postinfarction Research Group. RESULTS: A distinct relation was noted between left ventricular ejection fraction at rest and all-cause mortality. The highest mortality rate (9.9%) was noted in patients with an ejection fraction < 30%. Those not undergoing a study had a 1-year mortality rate of 6.2%. Peak exercise ejection fraction provided prognostic information similar to that of rest ejection fraction. Likewise, change in ejection fraction from rest to exercise did not appreciably improve prognostic impact. CONCLUSIONS: Rest left ventricular ejection fraction is an important prognostic index in patients receiving thrombolytic therapy. Peak exercise ejection fraction and the change in ejection fraction from rest to exercise do not provide appreciable prognostic data beyond those obtained at rest. Patients unable to exercise or those not having a rest study have a poor prognosis. When compared with the Multicenter Postinfarction Research Group data, there was strong evidence of a difference in survival in the two studies. At any level of ejection fraction, mortality was lower in TIMI II patients than in patients in the prethrombolytic era.

Resource utilization in treatment of acute myocardial infarction: staff-model health maintenance organization versus fee-for-service hospitals. The MITI Investigators. Myocardial Infarction Triage and Intervention.

OBJECTIVES: This study sought to compare the use of invasive procedures and length of stay for patients admitted with acute myocardial infarction to health maintenance organization (HMO) and fee-for-service hospitals. BACKGROUND: The HMOs have reduced costs compared with fee-for-service systems by reducing discretionary admissions and decreasing hospital length of stay. It has not been established whether staff-model HMO hospitals also reduce the rate of procedure utilization. METHODS: Using data from a retrospective cohort, we performed univariate and multivariate comparisons of the use of cardiac procedures, length of stay and hospital mortality in 998 patients admitted to two staff-model HMO hospitals and 7,036 patients admitted to 13 fee-for-service hospitals between January 1988 and December 1992. RESULTS: The odds of undergoing coronary angiography were 1.5 times as great for patients admitted to fee-for-service hospitals than for those admitted to HMO hospitals (odds ratio 1.5, 95% confidence interval [CI] 1.3 to 1.9). Similarly, the odds of undergoing coronary revascularization were two times greater in fee-for-service hospitals (odds ratio 2.0, 95% CI 1.6 to 2.5). However, higher utilization was strongly associated with the greater availability of on-site cardiac catheterization facilities in fee-for-service hospitals. The length of hospital stay, by contrast, was approximately 1 day shorter in the fee-for-service cohort (7.3 vs. 8.0 days, p < 0.05). CONCLUSIONS: Physicians in staff-model HMO hospitals use fewer invasive procedures and longer lengths of stay to treat patients with acute myocardial infarction than physicians in fee-for-service hospitals. This finding, however, appears to be associated with the lack of on-site catheterization facilities at HMO hospitals.

Post-infarction ventricular septal defect: the importance of site of infarction and cardiogenic shock on outcome.

Sixty-eight patients operated upon for post-infarction VSD from 1980-1987 have been reviewed to identify incremental risk factors which influence survival. Univariate and multivariate analysis was performed on 19 parameters and showed the following in decreasing order of importance to be significantly associated with non-survival: (1) operation within 24 h of occurrence of the VSD; (2) inferior infarct preceding the VSD; (3) requirement for inotropic support preoperatively; (4) preoperative cardiogenic shock; (5) a lower mean pulmonary artery pressure; (6) a lower mean wedge pressure; (7) a lower mean systolic pressure. The presence of a graft to the right coronary artery was associated with a better prognosis. Age, sex, diastolic blood pressure, balloon pumping, mean plasma urea, right atrial pressure, extent of coronary disease, number of coronary grafts, grafts to the left coronary system and method of myocardial preservation had no influence on survival.

Sex-related differences in outcome after ST-segment elevation myocardial infarction treated by primary angioplasty: data from the Zwolle Myocardial Infarction study.

BACKGROUND: Several studies have found that among patients with ST-elevation myocardial infarction (STEMI) treated by thrombolysis, female sex is associated with a worse outcome. The aim of this study was to investigate sex-related differences in clinical and angiographic findings and in long-term outcome in patients with STEMI treated with primary angioplasty. METHODS: Our population is represented by 1548 consecutive patients with STEMI treated by primary angioplasty from April 1997 to October 2001. All clinical, angiographic, and follow-up data were prospectively collected. RESULTS: Among 1548 patients, 353 were women (22.8%). Female sex was associated with more advanced age, higher prevalence of diabetes, hypertension, more advanced Killip class, longer ischemia time, and smaller vessel caliber. No difference was observed in terms of procedural success, postprocedural epicardial flow, myocardial perfusion, ST-segment resolution, and enzymatic infarct size. At 1-year follow-up, female sex was associated with a significantly higher 1-year mortality rate at univariate (9.3% vs 4.9 %, RR [95% CI] = 1.79 [1.14 to 2.8], P = .002) but not at multivariate analysis (RR [95% CI] = 1.41 [0.86 to 2.32], P = NS). CONCLUSIONS: This study shows that in patients with STEMI treated by primary angioplasty, women are associated with higher mortality rate in comparison with men, mainly because of their high-risk profile and angiographic features. Female sex did not emerge as an independent predictor of death.

Safety and accuracy of multidetector row computed tomography for early assessment of residual stenosis of the infarct-related artery and the number of diseased vessels after acute myocardial infarction.

BACKGROUND: Recent studies reveal that contrast-enhanced multidetector row computed tomography (MDCT) is a promising technique for noninvasive visualization of coronary artery stenoses. We investigated the safety and accuracy of MDCT for early assessment of the severity of residual stenosis of the infarct-related artery (IRA) and the number of diseased vessels in patients after acute myocardial infarction (AMI). METHODS AND RESULTS: Of 146 AMI cases admitted, 72 fit with criteria and underwent 16-slice MDCT (4 +/- 2 days after AMI) with beta-blockers. There were no complications except 1 patient who had from complete atrioventricular block. Results were compared with conventional coronary angiography (CCA) within 3 days. In 55 (73.3%) of 72 patients, all arteries were assessable. In total, the number of assessable arteries was 253 (87.8%), and 35 (12.2%) vessels were nonassessable, mostly because of motion artifacts and extensive calcification. Overall, 84 of the 115 lesions (> or = 50% lumen reduction) were correctly detected by MDCT (sensitivity 73.0%). The accuracy in classifying patients with nonsignificant, single-, or multiple-vessel diseases was 79.1%. The accuracy for residual lesions with >50% stenosis of IRA was 87.5%. There was a good correlation regarding the severity of residual stenosis of the IRA (0%, 1%-49%, 50%-89%, 90%-99%, or occlusion) between MDCT and CCA (Spearman correlation 0.94, P < .001). Lesions with 90% to 99% or occlusion of the IRA were accurately detected or ruled out in 31 of 36 cases (86.1%). CONCLUSIONS: With appropriate protocol, MDCT is safe and accurate in assessing the severity of IRA and the number of diseased vessels during the first week after AMI. It has the potential to provide triage for early management of patients after AMI.

Facilitated percutaneous coronary intervention for acute ST-segment elevation myocardial infarction: results from the prematurely terminated ADdressing the Value of facilitated ANgioplasty after Combination therapy or Eptifibatide monotherapy in acute Myocardial Infarction (ADVANCE MI) trial.

BACKGROUND: Facilitated percutaneous coronary intervention (PCI)--simultaneous administration of glycoprotein IIb/IIIa inhibitors and reduced-dose fibrinolytics before primary PCI for ST-segment elevation myocardial infarction (STEMI)--may be a promising reperfusion strategy. METHODS: The ADVANCE MI trial was intended to evaluate facilitated PCI in 5640 STEMI patients but was prematurely terminated as a result of slow recruitment over 12 months at 30 centers in the United States. Patients with STEMI with planned primary PCI were randomly assigned to receive eptifibatide + 50% of standard-dose tenecteplase (which equated to 0.25 mg/kg intravenous bolus) or eptifibatide + placebo before PCI and randomized in a 2 x 2 factorial design to unfractionated heparin or enoxaparin. RESULTS: A total of 148 patients were randomized (74 patients in each treatment arm) and formed the "as-randomized" intention-to-treat population. However, only 69 patients actually received eptifibatide + tenecteplase, and 77 actually received eptifibatide + placebo (2 patients did not receive eptifibatide and 4 patients randomized to tenecteplase did not receive this therapy)--these 146 patients formed the "as-treated" population. Among both populations, epicardial infarct artery patency and myocardial tissue perfusion on pre-PCI angiography were improved in the tenecteplase group, but ST-segment resolution at 60 minutes was similar. The frequency of the primary end point of death or new/worsening severe heart failure at 30 days was higher among patients treated with eptifibatide + tenecteplase in the "as-treated" (10% vs 3%, P = .09) and the "as-randomized" (11% vs 1%, P = .02) populations. Bleeding complications were 2-fold higher with eptifibatide + tenecteplase. Analysis of the results by treatment with unfractionated heparin versus enoxaparin demonstrated similar findings. CONCLUSIONS: Although definitive conclusions cannot be made as a result of the small sample size and premature study termination, facilitated PCI with eptifibatide + reduced-dose tenecteplase was associated with improved angiographic flow patterns, increases in adverse clinical outcomes, and higher bleeding rates compared with eptifibatide + placebo administered before primary PCI for STEMI.

Contemporary challenges in the management of acute myocardial infarction: ST-elevation myocardial infarction guidelines and the real world.

Timely reperfusion is the primary treatment goal for ST-segment elevation myocardial infarction. The recent American College of Cardiology/American Heart Association guidelines utilize time since symptom onset, anticipated time to treatment, patient risk factors, and center volume and experience to determine the optimal reperfusion strategy. There continues to be a considerable number of patients who do not receive reperfusion therapy and treatment delays are still too long. Institution-specific protocols which reflect current guidelines may increase the number of ST-segment elevation myocardial infarction patients who receive timely reperfusion.
