Left Ventricular Function, Congestion, and Effect of Empagliflozin on Heart Failure Risk After Myocardial Infarction. J Am Coll Cardiol 2024; 83:2233-2246. [PMID: 38588929 DOI: 10.1016/j.jacc.2024.03.405] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 03/25/2024] [Accepted: 03/26/2024] [Indexed: 04/10/2024]
Abstract
BACKGROUND Empagliflozin reduces the risk of heart failure (HF) hospitalizations but not all-cause mortality when started within 14 days of acute myocardial infarction (AMI). OBJECTIVES This study sought to evaluate the association of left ventricular ejection fraction (LVEF), congestion, or both, with outcomes and the impact of empagliflozin in reducing HF risk post-AMI. METHODS In the EMPACT-MI (Trial to Evaluate the Effect of Empagliflozin on Hospitalization for Heart Failure and Mortality in Patients with Acute Myocardial Infarction) trial, patients were randomized within 14 days of an AMI complicated by either newly reduced LVEF<45%, congestion, or both, to empagliflozin (10 mg daily) or placebo and were followed up for a median of 17.9 months. RESULTS Among 6,522 patients, the mean baseline LVEF was 41 ± 9%; 2,648 patients (40.6%) presented with LVEF <45% alone, 1,483 (22.7%) presented with congestion alone, and 2,181 (33.4%) presented with both. Among patients in the placebo arm of the trial, multivariable adjusted risk for each 10-point reduction in LVEF included all-cause death or HF hospitalization (HR: 1.49; 95% CI: 1.31-1.69; P < 0.0001), first HF hospitalization (HR: 1.64; 95% CI: 1.37-1.96; P < 0.0001), and total HF hospitalizations (rate ratio [RR]: 1.89; 95% CI: 1.51-2.36; P < 0.0001). The presence of congestion was also associated with a significantly higher risk for each of these outcomes (HR: 1.52, 1.94, and RR: 2.03, respectively). Empagliflozin reduced the risk for first (HR: 0.77; 95% CI: 0.60-0.98) and total (RR: 0.67; 95% CI: 0.50-0.89) HF hospitalizations, irrespective of LVEF or congestion, or both. The safety profile of empagliflozin was consistent across baseline LVEF and irrespective of congestion status. CONCLUSIONS In patients with AMI, the severity of left ventricular dysfunction and the presence of congestion was associated with worse outcomes. Empagliflozin reduced first and total HF hospitalizations across the range of LVEF with and without congestion.

Abstract
Factors predisposing the older person with acute myocardial infarction (MI) to develop heart failure (HF) include an increased prevalence of MI, multivessel coronary artery disease, decreased left ventricular (LV) contractile reserve, impairment of LV diastolic relaxation, increased hypertension, LV hypertrophy, diabetes mellitus, valvular heart disease, and renal insufficiency. HF associated with acute MI should be treated with a loop diuretic. The use of nitrates, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, aldosterone antagonists, beta-blockers, digoxin, and positive inotropic drugs; treatment of arrhythmias and mechanical complications; and indications for use of implantable cardioverter-defibrillators and cardiac resynchronization is discussed.

Abstract
BACKGROUND Impaired systolic function and congestive heart failure (CHF) are powerful predictors of adverse outcomes in patients with myocardial infarction (MI). However, there are little data in which both of these variables were assessed in heterogenous patients admitted from the emergency department for exclusion of ischemia. METHODS Consecutive patients admitted for MI exclusion who had ejection fraction (EF) measured were included. Systolic dysfunction was defined as EF <40%. Congestive heart failure was diagnosed based on clinical or x-ray evidence in the first 24 hours. Multivariate analysis was used to determine predictors of 30-day and 1-year mortality. RESULTS Of the 4,343 consecutive patients admitted, 3,682 (85%) had EF assessed (including 97% of the troponin I [TnI]-positive patients) and were included. One-year unadjusted mortality was 9.5%, but in the presence of systolic dysfunction or CHF, it increased to 22% and 26%, respectively. The most important multivariate predictors of 30-day and 1-year mortality were similar and included CHF (OR for 1-year mortality 2.5, 95% CI 1.9-3.4), TnI elevations (OR 2.0, 95% CI 1.5-2.6), and severe renal failure (OR 5.2, 95% CI 3.7-7.2). Systolic dysfunction was predictive of 1 year (OR 1.9, 95% CI 1.4-2.5) but not 30-day mortality. Results were similar in the 3,018 patients who were troponin-negative. CONCLUSIONS Congestive heart failure is an independent predictor of both short- and long-term mortality in patients admitted for MI exclusion. In contrast, systolic dysfunction predicts long-term but not short-term mortality. One cannot be used as a surrogate for the other.

Abstract
This article addresses issues related to acute myocardial infarction (MI) complicated by heart failure, particularly in elderly patients. Findings have shown that acute MI complicated by congestive heart failure (CHF) is associated with a high mortality, and that women with acute MI are more likely to be older and to develop CHF than men with acute MI. In general, management of CHF complicating acute MI is similar in older and younger patients. Actions discussed include hemodynamic monitoring; the administration of oxygen; and the use of morphine, diuretics, nitroglycerin, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, spironolactone, beta-blockers, calcium channel blockers, magnesium, digoxin, and positive inotropic drugs. The article also discusses measures for treating arrhythmias and for diagnosing mechanical complications.

Abstract
We investigate how the scale of estimation in risk-adjustment models for health-care costs affects the covariate effect, where the scale of interest for the covariate effect may be different from the scale of estimation. As an illustrative example, we use claims data to estimate the incremental costs associated with heart failure within one year subsequent to myocardial infarction. Here, the scale of interest for the effect of heart failure on costs is additive. However, traditional methods for modeling costs use predetermined scale of estimation - for example, ordinary least squares (OLS) regression assumes an additive scale while log-transformed OLS and generalized linear models with log-link assume a multiplicative scale of estimation. We compare these models with a new flexible model that lets the data determine the appropriate scale of estimation. We use a variety of goodness-of-fit measures along with a modified Copas test to assess robustness, lack of fit, and over-fitting properties of the alternative estimators. Biases up to 19% in the scale of interest are observed due to the misrepresentation of the scale of estimation. The new flexible model is found to appropriately represent the scale of estimation and less susceptible to over-fitting despite estimating additional parameters in the link and the variance functions.

Abstract
The development of heart failure and/or left ventricular systolic dysfunction (LVSD) in the setting of acute myocardial infarction (AMI) results in significant risk far above that of AMI independently. In patients admitted to the hospital for AMI, concomitant heart failure and/or LVSD on hospital admission or development of either or both of these conditions during admission are among the strongest predictors of inhospital death and are associated with significant increases in inhospital, 30-day, and long-term mortality and rehospitalization rates. Given the high risks in this population, aggressive treatment, comprising early initiation and sustained use of evidence-based treatments, is essential for improving prognosis.

Abstract
Large randomized clinical trials of bisoprolol, carvedilol and metoprolol have conclusively demonstrated the efficacy and confirmed safety of β-blockers in patients with chronic heart failure. Recently, the beneficial effects of carvedilol in patients with heart failure soon after an acute myocardial infarction have also been shown. Despite this, β-blockers remain under-prescribed in this condition. This is of particular importance as heart failure is common and increasing in prevalence. In this article, when to start β-blockade and which β-blocker to use is considered. Since carvedilol is the most studied β-blocker in heart failure and has a broad range of activities that extend beyond β-blockade, whether it has possible advantages over other β-blockers is discussed. Also, how the use of β-blockade might evolve with the introduction of device-related therapy in heart failure is considered.

Abstract
BACKGROUND Ejection fraction (EF) and renal failure (RF) are powerful predictors of mortality in patients with myocardial infarction (MI). There are limited data assessing the predictive value of EF and RF compared with clinical variables in patients without ST elevation using troponin as the diagnostic MI criteria. METHODS Consecutive patients admitted from the emergency department underwent serial assessment of cardiac markers, including troponin I. Abnormal EF was defined as < 50%; RF, as creatinine clearance (CrCl) < 60 mL/min. Multivariate analysis was used to compare clinical variables, CrCl, and EF for predicting short- and long-term outcomes. RESULTS A total of 3074 patients had EF assessed. Mild to moderately reduced EF and CrCl were present in 639 (21%) and 582 (19%) patients, with 403 (13%) and 233 (7.6%) having severe systolic dysfunction and severe RF, respectively. Abnormal EF and RF were both present in 13% of patients (1-year mortality 26%), whereas 52% had both normal EF and CrCl (1-year mortality 3.2%). The presence of either systolic dysfunction or RF increased mortality 3- to 4-fold compared with patients without either. The most important multivariate predictors of 1-year mortality were EF (OR 2.6 [95% CI 1.7-3.8, P < .0001]) and CrCl (OR 2.8 [95% CI 1.8-4.2, P < .0001]). CONCLUSIONS Both RF and EF are strong predictors of cardiac mortality in patients admitted for exclusion of MI. Prediction models that do not include these 2 variables will underestimate risk.

Abstract
Patients with heart failure, left ventricular systolic dysfunction, or both, after acute myocardial infarction have a poor prognosis. It is important to focus treatment on this high risk group to reduce the persistently high morbidity and mortality after acute myocardial infarction. As in chronic heart failure, there is now good evidence that inhibition of the renin-angiotensin-aldosterone system and sympathetic nervous system, with the appropriate drugs, can reduce morbidity and mortality. In addition to angiotensin converting enzyme inhibitors, angiotensin receptor blockers, and beta blockers, the aldosterone blocker eplerenone has now been shown to be effective in reducing adverse outcomes.

Abstract
PURPOSE OF REVIEW In the past few years, new clinical trials were conducted to determine the effectiveness of implantable cardioverter defibrillators (ICDs) for prevention of mortality in patients with ischemic and nonischemic cardiomyopathies. This paper aims to provide an overview of the current state of knowledge regarding ICD therapy in postinfarction patients. RECENT FINDINGS Postinfarction patients with severe left ventricular dysfunction are at high risk of sudden cardiac death. Antiarrhythmic therapy does not improve survival in such patients and, therefore, ICDs emerged as treatment of choice for both primary and secondary prevention of mortality after MI. The MADIT (Multicenter Automatic Defibrillator Implantation Trial) and MUSTT (Multicenter Unsustained Tachycardia Trial) trials were the first primary prevention ICD trials documenting a substantial reduction in mortality with an ICD in postinfarction patients with depressed ejection fraction, nonsustained ventricular tachycardia, and inducible sustained ventricular tachycardia. The recently completed MADIT II trial broadened indications for prophylactic use of ICD in postinfarction patients with ejection fraction of 30% or less without a requirement for additional risk stratifiers. The benefit from ICD therapy in patients with low ejection fraction was recently confirmed by results from the SCD-HeFT (Sudden Cardiac Death in Heart Failure) and COMPANION (Comparison of Medical Therapy, Pacing, and Defibrillation in Heart Failure) trials. SUMMARY Recent clinical trials established ICD as an important therapeutic modality for primary and secondary prevention of mortality in postinfarction patients.

Abstract
OBJECTIVES We sought to analyze clinical, angiographic, and outcome correlates of hemodynamic parameters in cardiogenic shock. BACKGROUND The significance of right heart catheterization in critically ill patients is controversial, despite the prognostic importance of the derived measurements. Cardiac power is a novel hemodynamic parameter. METHODS A total of 541 patients with cardiogenic shock who were enrolled in the SHould we emergently revascularize Occluded Coronaries for cardiogenic shocK (SHOCK) trial registry were included. Cardiac power output (CPO) (W) was calculated as mean arterial pressure x cardiac output/451. RESULTS On univariate analysis, CPO, cardiac power index (CPI), cardiac output, cardiac index, stroke volume, left ventricular work, left ventricular work index, stroke work, mean arterial pressure, systolic and diastolic blood pressure (all p < 0.001), coronary perfusion pressure (p = 0.002), ejection fraction (p = 0.013), and pulmonary artery systolic pressure (p = 0.047) were associated with in-hospital mortality. In separate multivariate analyses, CPO (odds ratio per 0.20 W: 0.60 [95% confidence interval, 0.44 to 0.83], p = 0.002; n = 181) and CPI (odds ratio per 0.10 W/m(2): 0.65 [95% confidence interval, 0.48 to 0.87], p = 0.004; n = 178) remained the strongest independent hemodynamic correlates of in-hospital mortality after adjusting for age and history of hypertension. There was an inverse correlation between CPI and age (correlation coefficient: -0.334, p < 0.001). Women had a lower CPI than men (0.29 +/- 0.11 vs. 0.35 +/- 0.15 W/m(2), p = 0.005). After adjusting for age, female gender remained associated with CPI (p = 0.032). CONCLUSIONS Cardiac power is the strongest independent hemodynamic correlate of in-hospital mortality in patients with cardiogenic shock. Increasing age and female gender are independently associated with lower cardiac power.

METHODS AND RESULTS The functional and prognostic significance of resting (201)Tl lung uptake was assessed in 124 consecutive patients with ischemic heart disease and ejection fraction </=35% undergoing rest-redistribution tomography to evaluate myocardial viability. (201)Tl lung uptake significantly correlated with pulmonary wedge pressure (r=0.66; P:<0.01) and with a restrictive physiology by Doppler echocardiography (P:<0.001). During a 13+/-13-month follow-up, 13 patients died and 23 patients required hospitalization as the result of worsening heart failure or nonfatal myocardial infarction (cumulative events rate 29%). Patients with events had a significantly higher (201)Tl lung/heart ratio (L/H) (P:<0.001). A L/H value >0.61 best separated patients with and without events (ROC area under curve 0.82). Event-free survival was significantly lower in patients with L/H >0.61 (P:<0. 001); L/H >0.61 (chi(2)=10.8; P:<0.001) and a restrictive filling pattern (chi(2)=3.6; P:<0.05) were independent predictors of events. The prognostic value of L/H was incremental over that obtained by clinical, echographic and Doppler data (global chi(2)=20.8). CONCLUSIONS In patients with severe postischemic left ventricular dysfunction undergoing rest-redistribution (201)Tl imaging, an increased lung tracer uptake showed incremental prognostic value over clinical and other imaging findings, providing clinically useful risk assessment.

Abstract
Older people with congestive heart failure associated with acute myocardial infarction should be treated with loop diuretic therapy. Class I indications for the use of early intravenous beta blockade in patients with acute myocardial infarction are patients without a contraindication to beta blockers who can be treated within 12 hours of onset of myocardial infarction; patients with continuing or recurrent ischemic pain; and patients with tachyarrythmias, such as atrial fibrillation with a rapid ventricular rate. Class I indications for the use of angiotensin-converting enzyme inhibitors during acute myocardial infarction are (1) patients within the first 24 hours of onset of a suspected acute myocardial infarction with ST segment elevation in two or more anterior precordial leads or with clinical heart failure in the absence of significant hypotension or contraindications to the use of angiotensin-converting enzyme inhibitors, (2) patients with myocardial infarction and a left ventricular ejection fraction of less then 40%, (3) and patients with clinical heart failure on the basis of systolic pump dysfunction during and after convalescence from acute myocardial infarction. No class I indications exist for using calcium channel blockers or magnesium during acute myocardial infarction.

Abstract
OBJECTIVE To establish the value of Doppler stroke distance measurement as a predictor of mortality risk following acute myocardial infarction. DESIGN Follow up study. SETTING Coronary care unit of a teaching and district general hospital. SUBJECTS 378 patients (mean age 61 years) with acute myocardial infarction followed up for a mean of five years (range 2-7 years); 299 (79%) patients received thrombolysis. MAIN OUTCOME MEASURES Stroke distance (the systolic velocity integral of blood flow in the aortic arch (percentage of age predicted normal value)); presence or absence of left ventricular failure on the admission chest radiograph; the codified admission ECG; death during follow up. RESULTS Mean (SD) stroke distance was 81 (19)% and five year survival 76%. For patients with stroke distance > 100% (n = 60), 82-100% (n = 134), 63-81% (n = 122), and < 63% (n = 62), the one month mortality rates were 0%, 1.5%, 4%, and 18%, respectively; the corresponding estimates for mortality at five years were 17%, 19%, 24%, and 43%. Survival was independently related to age (p < 0.0001), stroke distance (p < 0.0001), and chest radiograph appearance (p = 0.002), but not to ECG codes (p = 0.31) or receipt of thrombolysis (p = 0.60). The areas under receiver operator characteristic plots for stroke distance measurements were 82%, 76%, 71%, and 65% for deaths within one month, six months, one year, and two years, respectively. CONCLUSIONS The bedside measurement of stroke distance stratifies mortality risk after acute myocardial infarction. The predictive ability of this simple measure of left ventricular systolic function compares well with published accounts of the more complex measurement of ejection fraction.

Abstract
OBJECTIVES To examine clinical outcomes associated with optional beta blockade in a population of patients with evidence of heart failure after myocardial infarction. DESIGN AND PATIENTS Data from the acute infarction ramipril efficacy (AIRE) study were analysed retrospectively. At baseline 22.3% of the patients were receiving a beta blocker. To minimise confounding, beta blocker and diuretic treatments, presence of clinical signs of heart failure, left ventricular ejection fraction, and 16 other baseline clinical variables were simultaneously entered in a multivariate Cox regression model. In addition, the same analysis was repeated separately within a high and a low risk group of patients, as defined according to the need for diuretic treatment. RESULTS beta Blocker treatment was an independent predictor of reduced risk of total mortality (hazard ratio 0.66, 95% confidence interval (CI) 0. 48 to 0.90) and progression to severe heart failure (0.58, 95% CI 0.40 to 0.83) for the entire study population. There were similar findings in high risk patients requiring diuretics (0.59, 95% CI 0.40 to 0.86; and 0.58, 95% CI 0.38 to 0.89). CONCLUSIONS beta Blocker treatment is associated with improved outcomes in patients with clinical evidence of mild to moderate heart failure after myocardial infarction. Most importantly, high risk patients with persistent heart failure appear to benefit at least as much as lower risk patients with transient heart failure.

Abstract
OBJECTIVE Data from the Acute Infarction Ramipril Efficacy (AIRE) study were used in a cost-effectiveness analysis to determine the incremental cost per life-year gained (LYG) when the ACE inhibitor ramipril was added to conventional treatment in patients with heart failure after acute myocardial infarction. In the AIRE trial, the addition of ramipril significantly lowered rates of total mortality and rehospitalisation due to heart failure. DESIGN AND SETTING The cost-effectiveness analysis was conducted from the perspective of the Statutory Health Insurance (SHI) provider in Germany. A modelling approach was used which was based on secondary analysis of existing data, and costs were those incurred by SHI (i.e. expenses of SHI). In the base-case analysis, average case-related expenses of SHI were applied and LYG were quantified by the method of Kaplan and Meier. MAIN OUTCOME MEASURES AND RESULTS The incremental cost-effectiveness ratios of ramipril varied between 2500 and 8300 deutschmarks (DM) per LYG (1993 values for inpatient and 1995 values for outpatient treatment; DM1 approximately $US0.70), according to the treatment periods of 3.8 years and 1 year, respectively. In the sensitivity analysis, the robustness of the model and its results was shown when the extent of influence of different model variables on the base-case results was investigated. First, survival probability and LYG were estimated according to the Weibull method. Second, the dependency of the target variable (i.e. incremental cost per LYG) on random variables was described in a simulation. Third, the influence of the model variables on the target variable was quantified using a deterministic model. The variance of the target variable was broad and the hospitalisation impact of adding ramipril to conventional treatment was an independent variable with much greater influence on the target variable than the parameter of clinical effectiveness, i.e. the number of LYG. CONCLUSION Results of this evaluation showed that ramipril has a favourable incremental cost-effectiveness ratio for the treatment of heart failure in post myocardial infarction patients and can be considered an economical therapeutic agent from the perspective of SHI (third-party payer) in Germany.

Abstract
OBJECTIVE To assess the risk of mortality associated with hypertension and microalbuminuria in patients with acute myocardial infarction. DESIGN A prospective study. SETTING Intensive care units in three Italian general hospitals. PATIENTS In total 309 consecutive patients (including 97 women) aged 66.6 +/- 12.5 years, admitted to hospital for acute myocardial infarction. MAIN OUTCOME MEASURES Albumin excretion rate measured by radioimmunoassay of 24 h urine samples, on the first and third days after admission to hospital. In-hospital mortality rate among the patients stratified according to their history of hypertension and albumin excretion rate. RESULTS Of the patients, 147 had histories of hypertension. Forty-four per cent of the normotensive and 43% of the hypertensive subjects had microalbuminuria on the first day. On the third day the percentages were 25 and 29%, respectively. Twenty-two patients died before discharge from hospital. Patients were divided into four groups according to whether they had microalbuminuria or not and likewise for hypertension. Mortality rate among the subjects with hypertension and microalbuminuria combined was greater than those among the other three groups (P < 0.0001 on the first and third days). The relative hazard ratio was 11.7 on the first day, and 15.6 on the third day. In a multivariate Cox's model hypertension and microalbuminuria combined had a greater predictive power for mortality than either variable alone. Killip class, age, and creatinine kinases MB level were other significant predictors of death. CONCLUSIONS These results show that the combination of hypertension and microalbuminuria is associated with a greater risk of in-hospital mortality among subjects with acute myocardial infarction, independently of degree of heart failure and other possible confounders.

Abstract
This study was designed to determine the relationship between prognosis after myocardial infarction (MI) and left ventricular hypertrophy (LVH). Left ventricular hypertrophy diagnosed by electrocardiography according to the criteria of Sokolow and Lyon was noted in 57 of 223 patients (25.6%) on the pre-MI electrocardiogram (ECG), in 11.2% on an early post-MI ECG, and in 11.3% on the discharge ECG. In-hospital and 1-year postdischarge mortalities were significantly greater in patients with LVH noted on pre-MI ECG than in patients without prior LVH. There was no relationship between the presence of LVH on early post-MI ECGs and in-hospital or postdischarge 1-year mortality. Multivariate analysis revealed that evidence of LVH on a pre-MI ECG and acute congestive heart failure were independent predictors of cardiac death within 1 year of MI in patients over 70 years old. It is concluded that in patients over 70 years of age, the presence of LVH on a pre-MI ECG is a reliable predictor of post-MI prognosis.

Abstract
BACKGROUND This study was undertaken to assess whether albumin excretion rate (AER) increases during acute myocardial infarction (AMI) and whether it predicts in-hospital mortality. METHODS AND RESULTS The study was carried out in 496 subjects admitted to hospital for suspected AMI. Of these, 360 had evidence of AMI. The other 136 were studied as control subjects. AER was assessed by radioimmunoassay in three 24-hour urine collections performed on the first, third, and seventh days after admission. Left ventricular ejection fraction was measured by two-dimensional echocardiography in 254 subjects. AER adjusted for several confounders was higher in the AMI than the non-AMI group on the first (69.2+/-5.2 versus 27.3+/-8.5 mg/24 h, P<.0001) and third (30.3+/-2.7 versus 12.5+/-4.4 mg/24 h, P=.001) days, whereas no difference was present on the seventh day. When the subjects with heart failure were excluded, the difference between the two groups remained significant (first day, P<.0001; third day, P=.001). On the basis of classification of the 26 AMI patients who died in hospital according to whether they had normal AER, microalbuminuria, or overt albuminuria, mortality rate progressively increased with increasing levels of AER (P<.0001). In a Cox's proportional hazards model, AER was a better predictor of in-hospital mortality than Killip class or echocardiographic left ventricular ejection fraction. A cutoff value of 50 mg/24 h for first-day AER and 30 mg/24 h for third-day AER yielded a sensitivity of 92.3% and of 88.5% and a specificity of 72.4% and of 79.3%, respectively, for mortality. Adjusted relative risks for the two cutoff values were 17.3 (confidence limits, 4.6 to 112.7) and 8.4 (confidence limits, 2.4 to 39.3), respectively. CONCLUSIONS These data show that AER increases during AMI and that it yields prognostic information additional to that provided by clinical or echocardiographic evaluation of left ventricular performance.

Abstract
Ischemic heart disease is the most common cause of congestive heart failure, which often begins after acute myocardial infarction. To better delineate the clinical characteristics and outcomes of patients in whom congestive heart failure develops after acute myocardial infarction in the thrombolytic era, we prospectively evaluated patients enrolled in six of the TAMI trials. The study cohort comprised 1619 consecutive patients who had at least 1 mm of ST-segment elevation in two contiguous electrocardiographic leads within 6 hours of the onset of acute myocardial infarction and who received intravenous thrombolytic therapy. We prospectively collected clinical characteristics, baseline demographics, acute and 1-week angiographic variables, and in-hospital and 1-year outcome data. We performed stepwise multivariable regression analysis to determine the noninvasive and invasive predictors of the development of in-hospital congestive heart failure. Congestive heart failure developed in 301 patients in the hospital (19% of 1521 patients admitted were not in heart failure). These patients were likely to be older and female, have diabetes mellitus and previous myocardial infarction, and have an anterior wall myocardial infarction. On acute angiography, they had lower ejection fractions and a higher incidence of multivessel disease. Patency at 90 minutes was lower in the patients with congestive heart failure, and acute mitral regurgitation occurred in 1.6% versus 0.21% of patients without congestive heart failure. Patients with congestive heart failure had higher mortality, more in-hospital complications, and longer hospitalizations. At 1-year follow up, 21% of the patients in whom congestive heart failure developed had died versus 5% in the group without congestive heart failure. Predictors of new congestive heart failure included increased age, anterior wall myocardial infarction, lower pulse pressure and systolic blood pressure, diabetes mellitus, and the presence of rales on admission. The acute angiographic variables of reduced ejection fraction, increased number of diseased vessels, and attempted percutaneous intervention improved the concordance of the predictive model by 6%. Congestive heart failure remains a common clinical problem after acute myocardial infarction and is associated with a twofold increase in in-hospital morbidity and a fourfold increase in in-hospital and 1-year mortality. The development of congestive heart failure in the hospital can be predicted from noninvasive and invasive baseline characteristics. We present a simple table to predict congestive heart failure from baseline characteristics and invasive information.

Abstract
OBJECTIVES We tested the hypothesis that angiotensin-converting enzyme (ACE) inhibitor therapy decreases left ventricular (LV) mass in patients with a left ventricular ejection fraction (LVEF) > 40% and no evidence of heart failure after their first acute Q wave myocardial infarction (MI). BACKGROUND Recently, ACE inhibitor therapy has been shown to have an early mortality benefit in unselected patients with acute MI, including patients without heart failure and a LVEF > 35%. However, the effects on LV mass and volume in this patient population have not been studied. METHODS Thirty-five patients with a LVEF > 40% after their first acute Q wave MI were randomized to titrated oral ramipril (n = 20) or conventional therapy (control, n = 15). Magnetic resonance imaging (MRI) performed an average of 7 days and 3 months after MI provided LV volumes and mass from summated serial short-axis slices. RESULTS Left ventricular end-diastolic volume index did not change in ramipril-treated patients (62 +/- 16 [SD] to 66 +/- 17 ml/m2) or in control patients (62 +/- 16 to 68 +/- 17 ml/m2), and stroke volume index increased significantly in both groups. However, LV mass index decreased in ramipril-treated patients (82 +/- 18 to 73 +/- 19 g/m2, p = 0.0002) but not in the control patients (77 +/- 15 to 79 +/- 23 g/m2). Systolic arterial pressure did not change in either group at 3-month follow-up. CONCLUSIONS In patients with a LVEF > 40% after acute MI, ramipril decreased LV mass, and blood pressure and LV function were unchanged after 3 months of therapy. Whether the decrease in mass represents a sustained effect that is associated with a decrease in morbid events requires further investigation.

Abstract
Left ventricular (LV) systolic function and congestive heart failure (CHF) are important predictors of long-term mortality after acute myocardial infarction. The importance of transient CHF and the interaction of CHF and LV function on prognosis has not been studied in detail previously. In the TRAndolapril Cardiac Evaluation Study, 6,676 consecutive patients with acute myocardial infarction 1 to 6 days earlier had LV systolic function quantified as wall motion index (echocardiography), which is closely correlated to LV ejection fraction. To study the interaction of CHF and wall motion index on long-term mortality, separate analyses were performed in patients with different levels of LV function. Risk ratio (95% confidence intervals [CI]) were determined from proportional hazard models subgrouped by wall motion index or CHF adjusted for age and gender. Heart failure was separated into transient or persistent. Wall motion index and CHF are correlated. Furthermore, there is an interaction between wall motion index and CHF. The prognostic importance of wall motion index depends on whether patients have CHF or not: the risk ratio associated with decreasing 1 wall motion index unit is 3.0 (2.6 to 3.4) in patients with CHF, and 2.2 (1.7 to 2.9) in patients without CHF when adjusted for age and gender. Similarly, the prognostic importance of CHF depends on the level of wall motion index: the risk ratio associated with CHF is 3.9 (1.8 to 8.3) when the wall motion index is <0.8 and 1.9 (1.5 to 2.3) when the wall motion index is >1.6. Transient CHF is an independent risk factor (risk ratio 1.5, confidence interval [CI] 1.3 to 1.8) although milder than persistent CHF (risk ratio 2.8, CI 2.5 to 3.2).

Abstract
The objective of this study was to evaluate the prognostic accuracy and usefulness of neurohumoral determination as a risk stratification tool after acute myocardial infarction (AMI) by comparing the long-term prognostic value of subacute neurohumoral measurements with other established indicators of adverse outcome. The study included 145 patients with documented AMI. During a median follow-up of 3.7 years, 30 cardiovascular and 6 noncardiovascular deaths occurred. By univariate analysis, plasma atrial natriuretic factor (ANF) and endothelin levels were strongly related to long-term cardiovascular mortality. In multivariate models, both peptides added prognostic information to that obtained from clinical evaluation, but not to that obtained from left ventricular ejection fraction (LVEF). Estimation of the area under the receiver-operating characteristic curve showed comparable prognostic accuracy for LVEF (0.7788), plasma ANF (0.7795), plasma endothelin (0.7493), and Killip classification (0.8203), meaning that for all these prognostic indicators, a randomly selected patient from the group of patients dying will have a test value larger than that of a randomly selected patient from the group of surviving patients 75% to 82% of the time. The clinical usefulness of neurohumoral determination in routine risk stratification after AMI appears to be limited since no additional prognostic information to that provided by objective evaluation of LV systolic function is obtained. However, in patients for whom objective assessment of LV performance is not readily available, measurement of plasma ANF and endothelin may be helpful in identifying asymptomatic patients at risk for cardiac death.

Abstract
OBJECTIVE To determine how many lives would be saved if patients were routinely treated with ACE inhibitors after myocardial infarction according to the criteria of four recent major clinical trials, and to estimate the costs and benefits of these approaches. DESIGN Retrospective survey. SETTING The Nottingham Health District. PATIENTS Data from 7855 patients admitted between 1989 and 1990 were combined and the selection criteria of four major clinical trials (AIRE, SAVE, GISSI-3, and ISIS-4) were applied. RESULTS Of the patients admitted in Nottingham with confirmed myocardial infarcts 39% were eligible for AIRE and 8% for SAVE. In patients with suspected myocardial infarction as defined by the major trials, 60% would have been eligible for GISSI-3 and 63% for ISIS-4. Treating appropriate patients in accordance with these trials would have saved 20 (AIRE), 3 (SAVE), 4 (GISSI-3) and 5 (ISIS-4) lives each year in Nottingham at a drug cost of 5400 pounds, 33 pounds 791, 2730 pounds, and 4116 pounds per life per year saved respectively. CONCLUSIONS Short-term treatment with ACE inhibition appears to be cheaper but such an approach would save fewer lives. The AIRE study is the most applicable to current clinical practice but ACE inhibitors should be offered routinely to patients satisfying the criteria of any of the four major clinical trials.

Abstract
A large number of studies have shown the prognosis after acute myocardial infarction (AMI) to be favorably affected by treatment with beta blockers. Whether such treatment also will have a favorable effect on the prognosis in patients in whom AMI was not confirmed has not been shown. A study was undertaken at Sahlgren's Hospital, Göteborg, to determine risk indicators for death and prognosis among 1,443 patients in whom AMI was not confirmed and who survived hospitalization in relation to whether or not beta blockers were prescribed at discharge. One-year mortality was determined and p values were corrected for differences at baseline. Of the 1,443 patients who participated in the analyses, 44% were prescribed beta blockers. They differed from the remaining patients by younger age, predominance of men, a more frequent history of AMI, angina pectoris, and hypertension, and a less frequent history of congestive heart failure. Patients in whom beta blockers were prescribed had a 1-year mortality of 6% compared with 16% in those not on beta blockers (p < 0.001). The difference was similar in various subgroups according to clinical history.

Abstract
BACKGROUND Current knowledge of risk assessment in survivors of myocardial infarction is largely based on data gathered before the advent of thrombolysis. It must be determined whether and to what extent available information and proposed criteria of prognostication are applicable in the thrombolytic era. METHODS AND RESULTS We reassessed risk prediction in the 10,219 survivors of myocardial infarction with follow-up data available (ie, 98% of the total) who had been enrolled in the GISSI-2 trial, relying on a set of prespecified variables. The 3.5% 6-month all-cause mortality rate of these patients compared with the higher value of 4.6% found in the corresponding GISSI-1 cohort, originally allocated to streptokinase therapy, indicates a 24% reduction in postdischarge 6-month mortality. On multivariate analysis (Cox model), the following variables were predictors of 6-month all-cause mortality: ineligibility for exercise test for both cardiac (relative risk [RR], 3.30; 95% confidence interval [CI], 2.36-4.62) and noncardiac reasons (RR, 3.28; 95% CI, 2.23-4.72), early left ventricular failure (RR, 2.41; 95% CI, 1.87-3.09), echocardiographic evidence of recovery phase left ventricular dysfunction (RR, 2.30; 95% CI, 1.78-2.98), advanced (more than 70 years) age (RR, 1.81; 95% CI, 1.43-2.30), electrical instability (ie, frequent and/or complex ventricular arrhythmias) (RR, 1.70; 95% CI, 1.32-2.19), late left ventricular failure (RR, 1.54; 95% CI, 1.17-2.03), previous myocardial infarction (RR, 1.47; 95% CI, 1.14-1.89), and a history of treated hypertension (RR, 1.32; 95% CI, 1.05-1.65). Early post-myocardial infarction angina, a positive exercise test, female sex, history of angina, history of insulin-dependent diabetes, and anterior site of myocardial infarction were not risk predictors. On further multivariate analysis, performed on 8315 patients with the echocardiographic indicator of left ventricular dysfunction available, only previous myocardial infarction was not retained as an independent risk predictor. CONCLUSIONS A decline in 6-month mortality of myocardial infarction survivors, seen within 6 hours of symptom onset, has been observed in recent years. Ineligibility for exercise test, early left ventricular failure, and recovery-phase left ventricular dysfunction are the most powerful (RR, > 2) predictors of 6-month mortality among patients recovering from myocardial infarction after thrombolysis. Qualitative variables reflecting residual myocardial ischemia do not appear to be risk predictors. The lack of an independent adverse influence of early post-myocardial infarction angina on 6-month survival represents a major difference between this study and those of the prethrombolytic era.

Abstract
To evaluate the clinical characteristics of patients with anteroseptal myocardial infarction (MI) initially presenting with pulmonary edema, we analyzed 58 patients with anteroseptal MI who underwent emergency coronary arteriography that revealed single-vessel disease of the left anterior descending coronary artery. Of the 58 patients, pulmonary edema was observed in 24 patients (group A) and was absent in 34 patients (group B). Pulmonary capillary wedge pressure was significantly higher, and cardiac output was significantly lower in group A. The site of coronary stenosis, maximum serum creatinine kinase value, and wall motion point score did not differ between the two groups. However, the incidence of previous hypertension and posterior wall thickness > or = 11 mm was significantly higher in group A than in group B (p < 0.001 and p < 0.05, respectively). Thus, impaired left ventricular diastolic filling in the non-MI segments due to higher incidence of hypertension and left ventricular hypertrophy was considered to be the possible cause of pulmonary edema.
