To study the additive benefits of routine stent implantation in patients undergoing primary percutaneous transluminal coronary angioplasty (PTCA) at experienced centers, we compared the outcomes of the 982 patients undergoing PTCA for acute myocardial infarction (AMI) in the Primary Angioplasty in Myocardial Infarction-2 (PAMI-2) trial (only 1% of whom were stented) to the 312 patients in the PAMI Stent Pilot Trial (236 [76%] of whom were stented). The inclusion and exclusion criteria, PTCA methodology, and definitions used were prespecified to be identical between the two trials. Compared to the primary PTCA approach in PAMI-2, the strategy of stenting all eligible lesions in the PAMI Stent Pilot Trial was associated with reduced rates of in-hospital death (0.6% vs 2.7%, P = 0.03), reinfarction (1.3% vs 4.6%, P = 0.008), recurrent ischemia (3.5% vs 11.6%, P < 0.0001), target vessel revascularization (7.3% vs 11.4%, P = 0.04), and a shorter hospital stay (6.4 ± 4.4 vs 7.1 ± 6.2 days, P = 0.01). By multiple logistic regression analysis in 1,294 patients, stent implantation versus PTCA only was the strongest predictor of freedom from the composite in-hospital end point of death, reinfarction, or target vessel revascularization (TVR) (8.3% vs 15.0%, multivariate odds ratio = 0.4, P < 0.0001). These data strongly suggest that despite the excellent results achieved when primary PTCA is performed by experienced operators, the short-term outcomes of mechanical reperfusion can be further improved by a primary stent strategy. 相似文献

BACKGROUND: Female patients with acute myocardial infarction (MI) exhibit higher unadjusted in-hospital mortality rates compared to male patients. However, contradictory evidence exists on whether this survival disadvantage disappears after adjustment for age and other prognostic factors. This study, based on a countrywide survey of consecutive unselected patients with acute MI, examined whether female gender is an independent predictor of poor short-term outcome and less intensive in-hospital treatment. METHODS: Data on a total of 7433 patients were analyzed. RESULTS: The mean age was 64+/-13 years and the proportion of females in this population was 23%. Univariate and multivariate predictors of in-hospital mortality in female patients were estimated. Unadjusted in-hospital mortality rates of women were significantly higher compared to men (17.7 vs. 8.6, p<0.001). In multivariate analysis, female gender was an independent predictor of in-hospital mortality in the total population [relative risk (RR)=1.29, 95% confidence interval (CI)=1.02-1.64, p=0.036]. The RR of women for in-hospital death was exaggerated among younger patients, aged <55 years (RR=3.84, 95% CI=1.07-13.74, p=0.039). Female gender was also independently and inversely associated with administration of thrombolytic treatment (RR=0.724, 95% CI=0.630-0.831, p=<0.001). CONCLUSION: Although female gender is an independent predictor of higher post-MI in-hospital mortality with a pronounced effect among younger patients, women are less likely to receive thrombolysis than men. Based on the results from this countrywide study, we should consider women, especially of younger age, as patients at particular high risk, who contrary to common practice, deserve more intensive and aggressive in-hospital treatment. 相似文献

Elderly patients are increasingly referred to percutaneous coronary interventions (PCIs). Recent reports suggest complications rates are declining in the elderly. We sought to determine whether procedural and in-hospital outcomes are different in patients aged > or = 75 years undergoing nonemergent PCI as compared to patients age < 75 years. The outcome of 266 consecutive patients age > or = 75 years undergoing nonemergent PCI was compared to that of 1,681 consecutive patients age < 75 years. Compared with younger patients, greater proportions of elderly patients were women and had a history of hypertension, peripheral vascular disease, and cerebral vascular events. Elderly patients had more extensive coronary involvement. Procedural success was similar in both groups (94%). The in-hospital cardiac death rate was significantly higher in the elderly patients (2.3% vs. 0.7%; P = 0.03). Aged patients also had a significantly higher incidence of vascular and bleeding complications. Blood transfusion was required more often in the elderly group (4.5% vs. 2.6%; P = 0.07). The hospitalization length was significantly higher in the elderly group (4.1 +/- 6.0 vs. 2.5 +/- 4.3 day; P = 0.0004). By multivariate logistic regression (adjusted for baseline clinical and angiographic variables), age > or = 75 years was found to be an independent predictor of in-hospital cardiac death (odds ratio = 3.9; 95% CI = 1.3-11.5; P = 0.015). Although PCI is technically successful in patients aged > or = 75 years; it is associated with more acute cardiac and vascular complications and higher in-hospital cardiac mortality. 相似文献

BACKGROUND: Preinfarction angina improves survival after acute myocardial infarction (AMI) in nonelderly but not elderly patients in the thrombolytic era. However, it remains unclear whether preinfarction angina has a beneficial effect on clinical outcome in elderly patients undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS: The study group comprised 484 anterior AMI patients who were admitted within 24 h of onset and underwent emergency PCI. Patients were divided into 2 groups: those aged < 70 years (nonelderly patients, n = 290) and those aged > or = 70 years (elderly patients, n = 194). Angina within 24 h before AMI was present in 42% of nonelderly patients and in 37% of elderly patients. In nonelderly patients, preinfarction angina was associated with a lower in-hospital mortality rate (1% vs 7%, p = 0.02). Similarly, in elderly patients, preinfarction angina was associated with a lower in-hospital mortality rate (6% vs 16%, p = 0.03). Multivariate analysis showed that the absence of preinfarction angina was an independent predictor of in-hospital mortality in both nonelderly (odds ratio 4.20; 95% confidence interval (CI) 1.20-10.6; p = 0.04) and elderly patients (odds ratio 3.04; 95%CI 1.06-18.1; p = 0.04). CONCLUSIONS: Angina within the 24 h before AMI is associated with better in-hospital outcomes in elderly and nonelderly patients. 相似文献

In-hospital and 1-year mortality in 1,524 women after myocardial infarction. Comparison with 4,315 men 总被引:15,自引:0,他引:15
We determined in-hospital and 1-year prognoses after acute myocardial infarction (MI) in 5,839 consecutive patients derived from 14 of 21 coronary care units in Israel during 1981-1983. Age-adjusted in-hospital mortality was 23.1% in 1,524 women and 15.7% in 4,315 men (p less than 0.0005). One-year age-adjusted mortality rates in patients surviving hospitalization were 11.8% in women and 9.3% in men (p = 0.03). Cumulative age-adjusted 1-year mortality rates were 31.8% in women and 23.1% in men (p less than 0.0005). Relative odds of mortality, covariate-adjusted for major prognostic factors that included age, prior MI, congestive heart failure, and infarct location by electrocardiogram, indicated that female gender was independently and significantly associated with increased mortality both during hospitalization (relative odds, 1.72; 95% confidence interval, 1.45-2.04) and at 1 year after discharge (relative odds, 1.32; 95% confidence interval, 1.05-1.66). In separate multivariate analyses for each gender, a major factor that emerged as a predictor of outcome in women, but not in men, was a reported history of diabetes mellitus, both for in-hospital mortality and for 1-year mortality. However, even in the nondiabetics in this population, female gender was a significant, independent predictor of in-hospital mortality. The findings of the present study substantiate that women fare worse than men after suffering an acute MI, that increased age does not fully account for the increased mortality in women, and that diabetic women are at particularly high risk once MI has occurred. 相似文献

Prognostic significance of new atrial fibrillation and its relation to heart failure following acute myocardial infarction 总被引:2,自引:0,他引:2

BACKGROUND: New-onset atrial fibrillation (AF) after acute myocardial infarction (AMI) frequently occurs in association with postinfarction complications, particularly with heart failure (HF). AIMS: To evaluate whether postinfarction HF is associated with the subsequent development of AF and whether AF independently predicts poorer prognosis. METHODS AND RESULTS: We examined 650 patients with AMI and compared patients with AF (n=320) to those without (n=330). AF patients were classified as either early AF (n=208)-patients who developed AF within 24 h of symptom onset or late AF (n=112)-patients who had AF thereafter. We compared outcomes between these groups, adjusting for differences in baseline characteristics and postinfarction HF. Heart failure was the most important predictor of AF. In most patients, AF occurred secondary to HF. AF patients had poorer outcomes, including higher in-hospital and 7-year mortality. After multivariate adjustment, overall, AF was not an independent predictor of in-hospital [odds ratio (OR)=0.70) and 7-year [relative risk (RR)=1.14] mortality, but late AF remained an independent predictor of 7-year (RR=2.48, 95% confidence interval, 1.26-4.87) mortality. CONCLUSIONS: Heart failure mostly preceded the occurrence of new-onset atrial fibrillation after acute myocardial infarction, but only late atrial fibrillation was independently related to long-term mortality. 相似文献

Background Fewer studies were performed to evaluate the relationship between magnesium level in serum and mortality after percutaneous coronary intervention(PCI) for patients with ST-segment elevation myocardial infarction(STEMI). In this study, we explored the association between magnesium level in serum and adverse outcomes in STEMI patients undergoing PCI. Methods All 1476 consecutive patients with STEMI undergoing PCI were divided into three groups, magnesium 0.8(n = 331), 0.8-1.0(n = 1100) and 1.0 mmol/L(n = 45)based on the levels of serum magnesium. The association between magnesium and in-hospital and one-year death was analyzed. With multivariate logistic regression analysis. Results The in-hospital mortality(6.3% vs. 2.5%vs. 4.4%, P = 0.004) and major adverse clinical events(7.9% vs. 3.6% vs. 6.7%, P = 0.005) were significantly higher in patients with hypomagnesemia. Kaplan-Meier analysis demonstrated that the cumulative rate of oneyear mortality after PCI was higher in patients with hypomagnesemia(Log-rank = 9.89, P = 0.007). Conclusion Hypomagnesemia is a predictor of higher in-hospital and one-year mortality after PCI for STEMI patients. 相似文献

Whether percutaneous coronary intervention (PCI) alone is safe in patients with moderate or severe aortic stenosis (AS) and coexisting coronary artery disease (CAD), and whether aortic valve replacement (AVR) can be deferred in patients with moderate AS by undergoing PCI alone is not known. We conducted a retrospective study of surgically inoperable patients with AS who underwent PCI (moderate AS, n = 28; and severe AS, n = 28) and compared to those with AVR (n = 55). The clinical characteristics, procedural complications, in-hospital and long-term clinical outcomes of PCI were compared. Baseline and procedural characteristics were similar except that lower age, hypertension, and renal impairment were seen in the AVR group. In-hospital complications were comparable among the 3 groups. Six-month and 1-year rates of myocardial infarction (MI), non-Q-wave MI, death and out-of-hospital death were similar between AVR and moderate AS patients (p = NS) and significantly high (p < 0.04) in patients with severe AS. On multivariate analysis, severe AS was the only significant predictor of 6-month and 1-year mortality. Our study suggests that PCI is safe in patients with moderate AS and coexisting CAD but is associated with poor outcomes in patients with severe AS. 相似文献

Previous studies have demonstrated a significant interaction between gender and age after medically treated acute myocardial infarction (AMI), when younger women were found to have a higher mortality rate than younger men, but the mortality rate for older men and women was similar. The study objective was to determine whether a gender-age interaction exists for AMI treated exclusively with primary angioplasty. This analysis was a retrospective cohort study of 9,015 consecutive patients who underwent primary angioplasty for AMI in New York State from 1997 to 1999. The primary end point of interest was in-hospital mortality. A logistic regression model was constructed to determine the relation between gender and mortality among patients with AMI treated with angioplasty. Additional analyses were performed to test whether a mortality difference existed according to age. In-hospital mortality rate was twofold higher in women than in men (6.7% vs 3.4%, p <0.001). After adjusting for age, co-morbid conditions, and hemodynamic status by multivariable logistic regression analysis, the odds ratio for in-hospital death for women was no longer significant (odds ratio 1.21, 95% confidence interval 0.69 to 2.10, p = 0.51). Among patients <75 years of age, women had a 37% increased risk of in-hospital mortality (adjusted odds ratio 1.37, 95% confidence interval 1.01 to 1.98, p = 0.04), whereas there was no significant difference in mortality between men and women who were >or=75 years of age. In conclusion, female gender was found to be an independent predictor of in-hospital mortality in patients <75 years of age after primary angioplasty for AMI. 相似文献

BACKGROUND: Recurrent acute myocardial infarction (AMI) is a deteriorated condition with high in-hospital morbidity and mortality, but the predictors of in-hospital outcome after primary percutaneous coronary intervention (PCI) for repeat AMI remain unclear. METHODS AND RESULTS: Using the AMI-Kyoto Multi-Center Risk Study database, clinical background, angiographic findings, results of primary PCI, and in-hospital prognosis were retrospectively compared between primary PCI-treated AMI patients with previous myocardial infarction (MI) (repeat-MI patients, n=235) and those without previous MI (first-MI patients, n=1,550). The repeat-MI patients had higher prevalence of Killip class>or=3 at admission, larger number of diseased vessels, and a significantly higher in-hospital mortality rate than the first-MI patients. On multivariate analysis, number of diseased vessels>or=2 or diseased left main trunk (LMT) on initial coronary angiography was the independent positive predictor of in-hospital mortality in the repeat-MI patients, not in the first-MI patients, whereas acquisition of Thrombolysis In Myocardial Infarction 3 flow in the infarct-related artery immediately after primary PCI and elapsed time<24 h were the negative predictors in the first-MI patients, not in the repeat-MI patients. CONCLUSIONS: Number of diseased vessels>or=2 or diseased LMT on initial coronary angiography is an independent risk factor of in-hospital death in recurrent-AMI patients undergoing primary PCI. 相似文献

We evaluated the in-hospital and 1-year outcomes and predictors of admission heart failure in patients with non-ST-elevation acute coronary syndromes (NSTE-ACSs) without previous heart failure. We analyzed 4,825 patients with NSTE-ACS without a history of congestive heart failure who were included in the multicenter Canadian ACS Registries. Patients in Killip's class II/III on admission (n = 559, 11.6%) were compared with patients in Killip's class I. Patients with heart failure on admission were older (72 [64, 79] vs 64 [54, 73] years, p < 0.0001), with higher baseline creatinine levels (96 vs 88 mmol/dl, p <0.0001), more diabetes (32.2% vs 22.8%, p < 0.0001), hypertension (58% vs 52.4%, p = 0.014), previous myocardial infarction (MI; 38.9% vs 30.3%, p < 0.0001), previous stroke (13.5% vs 7.4%, p < 0.0001), and had more ST depression on admission (27.7% vs 17.3%, p < 0.0001). In-hospital treatment was similar except for a lower rate of aspirin therapy and fewer coronary interventions. Crude event rates were significantly higher in patients with heart failure (in-hospital death 3.6% vs 1.1%, p < 0.0001; death or MI 7.9% vs 4.7%, p = 0.0011; stroke 1.1% vs 0.4%, p = 0.03). One-year event rates were also higher in patients with heart failure (death 14.6% vs 4.4%, p < 0.0001; MI 9.3% vs 6.6%, p = 0.03; death or MI 21.5% vs 10.3%, p < 0.0001). Variables independently associated with heart failure were age (odds ratio 1.57, 95% confidence interval 1.43 to 1.73), diabetes mellitus (odds ratio 1.53, 95% confidence interval 1.24 to 1.89), admission ST depression (odds ratio 1.52, 95% confidence interval 1.22 to 1.90), previous MI, and baseline creatinine. Heart failure on admission was an independent predictor of in-hospital death, death or MI, and stroke and of 1-year death and death or MI. In conclusion, in patients with NSTE-ACS, heart failure on admission is associated with increased short- and long-term rates of death and MI. 相似文献

Patients with ST-elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) are increasingly being treated with percutaneous coronary intervention (PCI) and we sought to determine risk of adverse outcomes by type of MI. Patients enrolled in the National Heart, Lung, and Blood Institute Dynamic Registry from 1999 to 2004 who presented with an acute MI as an indication for PCI were studied. Baseline data and in-hospital and 1-year outcomes were compared based on ST-segment elevation (STEMI, n = 903; NSTEMI, n = 583) at presentation. Patients with STEMI were younger, had fewer co-morbidities, and had less extensive coronary artery disease than did patients with NSTEMI. Angiographic success and periprocedural complications were similar by MI type. In-hospital coronary artery bypass grafting, stroke, bleeding and recurrent MI were similar but mortality was higher in patients with STEMI (4.0% vs 1.4%, p = 0.004). Cardiogenic shock was associated with the greatest risk of in-hospital death (odds ratio 26.7, 95% confidence interval 11.4 to 62.3, p = 0.0001), but STEMI was also independently predictive of mortality. At 1 year, there was no influence of MI type on outcome. Age, cardiogenic shock, renal disease, peripheral vascular disease, and cancer were predictive of death and MI. Multivessel disease and a larger number of >50% lesions were associated with the need for repeat revascularization. In conclusion, STEMI was associated with a higher likelihood of in-hospital death than was NSTEMI, but long-term outcomes after PCI were independent of MI type. At 1 year, associated co-morbidities were strongly associated with death and MI, whereas only angiographic characteristics predicted the need for repeat revascularization. 相似文献

OBJECTIVES: The aim of the study was to assess if QT dispersion and RR interval on the standard 12-lead electrocardiogram (ECG) predict cardiac death and late arrhythmic events in postinfarction patients with low left ventricular ejection fraction (LVEF). QT dispersion on a standard electrocardiogram (ECG) is a measure of repolarization inhomogeneity, but its prognostic meaning in myocardial infarction (MI) survivors is unclear, especially in patients with left ventricular dysfunction. RR interval has been shown to predict mortality in post-MI patients, but its prognostic power has not been compared with other noninvasive risk factors. METHODS: Retrospective cohort study. Ninety patients were identified, from a series of 547 consecutive postinfarction patients admitted to our institution for phase II cardiac rehabilitation, as having a LVEF of <0.40 at two-dimensional echocardiography (mean LVEF 0.35+/-0.04; range 0.20-0.39). QT dispersion and RR interval were analyzed on the admission 12-lead electrocardiogram, 20+/-10 (range 8-45) days after MI, using specially designed software. Additional risk markers were collected from clinical variables, signal-averaged ECG and Holter recording. RESULTS: During 24+/-18 (range 1-63) months of follow-up, 10 of 90 patients (11%) died, all from cardiac causes, and there were 18 late arrhythmic events, defined as sudden death or the occurrence of a sustained ventricular arrhythmia > or =5 days after the index MI. QT interval and dispersion were not significantly prolonged in patients who died compared to survivors and not significantly different between patients with and without arrhythmic events. Mean RR interval from standard ECG was significantly shorter in patients with both cardiac death (682+/-99 vs. 811+/-134 ms; P=0.004) and arrhythmic events (720+/-100 vs. 818+/-139 ms; P=0.006). A Cox proportional hazards model identified RR interval from standard ECG (P<0.001) and a history of more than one MI (P=0.002) as significant predictors of cardiac death independent of thrombolytic therapy, LVEF, filtered QRS complex duration at signal-averaged ECG, mean RR and its standard deviation at 24-h Holter monitoring. CONCLUSIONS: Measurement of QT interval and dispersion 3 weeks after MI has no prognostic power in patients with LV dysfunction after a recent MI. RR interval on standard 12-lead ECG is as good a prognostic indicator as other, more expensive, noninvasive markers. These findings may be relevant in this era of limited health care resources. 相似文献

Prognostic value of admission myeloperoxidase levels in patients with ST-segment elevation myocardial infarction and cardiogenic shock 总被引:2,自引:1,他引:2

Inflammation plays a critical role in acute myocardial infarction. One inflammatory marker is myeloperoxidase (MPO). Its role as a predictor of in-hospital death in patients with ST-segment elevation myocardial infarction (STEMI) presenting with cardiogenic shock (CS) is unclear. Therefore, the aim of this study was to investigate the role of MPO as a predictor of in-hospital death in patients with STEMIs presenting with CS and treated with primary percutaneous coronary intervention. In 38 consecutive patients with CS complicating STEMIs who were treated with primary percutaneous coronary intervention, serum MPO levels were measured at coronary care unit admission using a commercially available enzyme-linked immunosorbent assay. The primary study end point was in-hospital cardiac death. Among the 38 patients included in the study, 20 died during their coronary care unit stays, whereas 18 survived. Compared with patients who survived, patients who died showed, at coronary care unit admission, higher serum MPO levels (81 +/- 28 vs 56 +/- 23 ng/ml, p <0.006). After controlling for different baseline clinical, laboratory, and angiographic variables, baseline serum MPO level was an independent predictor of in-hospital mortality on multivariate analysis (odds ratio 3.9, 95% confidence interval 1.8 to 7.5, p <0.001). In conclusion, admission MPO concentration is an independent predictor of in-hospital mortality in patients with STEMIs presenting with CS. 相似文献

We evaluated the association between severity of sepsis and in-hospital mortality in 150 patients with non-surgical sepsis at a regional referral hospital in Uganda. In-hospital mortality occurred in 5 of 52 (9.6%) patients with sepsis, 24 of 71 (33.8%) patients with severe sepsis, and 16 of 27 (59.3%) patients with septic shock. In the multivariate analysis, the identification of severe sepsis (adjusted hazard ratio [AHR] = 2.9, 95% confidence interval [CI] = 1.0-8.2, P = 0.04), septic shock (AHR = 5.7, 95% CI = 1.6-20.3, P = 0.007), and dysfunction of three or more organs (AHR = 2.9, 95% CI = 1.1-7.3, P = 0.03) increased the risk of in-hospital mortality. Adding aggregate organ dysfunction to the multivariate equation that included the sepsis category statistically significantly improved the model, but the opposite did not. Predictors of mortality were easily measurable and could be used to risk stratify critically ill patients in resource-constrained settings. 相似文献

Creatine kinase-MB (CK-MB) enzyme elevations were shown to affect cardiac prognosis following percutaneous coronary interventions (PCIs). This study examined whether recurrent episodes of CK-MB elevation following repeated PCIs may be associated with a cumulative adverse prognostic risk. We studied 767 consecutive patients (age, 64 +/- 11 years; 69% male) who underwent two consecutive PCI procedures on two separate hospitalizations (mean interval, 121 +/- 110 days). Patients were stratified into four groups according to number of episodes of any (> 4 ng/ml) postinterventional CK-MB rise (no elevation, previously elevated, currently elevated, or elevated at the time of both procedures; n = 403, 107, 153, and 104 patients, respectively). In-hospital clinical outcomes (death, Q-MI, and repeat revascularization) and up to 1-year follow-up events were obtained. Recurrent episodes of CK-MB elevation were associated with increased in-hospital mortality (3.8% vs. 0.9% vs. 0% vs. 0%, P = 0.0003), increased cumulative mortality (18.9% vs. 5.9% vs. 4.3% vs. 4.3%, P = 0.0003) and cumulative Q wave MI (8.0% vs. 4.9% vs. 1.0% vs. 0.8%, P = 0.005) at 1 year, and lower overall cardiac event-free survival at follow-up (66.8% vs. 80.5% vs. 88.8% vs. 88.8%, P = 0.0001 for patients with twice, current, previous, and no CK-MB elevation, respectively). By multivariate analysis, CK-MB elevated at the time of both procedures, was the strongest independent predictor for cumulative mortality (OR 3.4, 95% CI 1.6-7.1, P = 0.001) or any adverse cardiac events (OR 2.6, 95% CI 1.6-4.3, P = 0.0002). We conclude that cumulative episodes of periprocedural CK-MB elevation are associated with an incremental adverse prognostic risk including mortality and Q-wave MI. Thus, measures aimed at reducing subsequent CK-MB rise may be warranted in particular among patients with a prior history of PCI related CK-MB elevation. 相似文献

OBJECTIVES: We sought to determine the importance of chest pain on presentation as a predictor of in-hospital treatment and mortality in myocardial infarction (MI) patients with left bundle-branch block (LBBB). BACKGROUND: Left bundle-branch block patients have a high mortality after MI but are unlikely to receive reperfusion therapy despite evidence from clinical trials demonstrating the efficacy of thrombolytic therapy. Nearly half of MI patients with LBBB present without chest pain. METHODS: We studied the clinical features, treatment and in-hospital survival of 29,585 patients with LBBB enrolled in the National Registry of MI 2 June 1994 through March 1998). Multivariate logistic regression was used to assess the independent effect of chest pain on reperfusion decisions and in-hospital mortality. RESULTS: Left bundle-branch block patients with chest pain were greater than five-fold more likely to receive reperfusion therapy (13.6% vs. 2.6%) than LBBB patients without chest pain; they were also more likely to receive aspirin, beta-adrenergic blocking agents, heparin and nitrates (all p < 0.0001). Unadjusted in-hospital mortality was 18% in patients with chest pain and 27% in patients without chest pain. Adjusting for patient characteristics reduced the odds ratio associated with the absence of chest pain from 1.47 (95% confidence interval: 1.41 to 1.54) to 1.21 (95% confidence interval: 1.12 to 1.30). The remainder of the mortality difference was caused by the undertreatment of patients without chest pain, particularly the low utilization of aspirin and beta-blockers. CONCLUSIONS: Left bundle-branch block patients with MI who present without chest pain are less likely to receive optimal therapy and are at increased risk of death. Prompt recognition and treatment of this high-risk subgroup should improve survival. 相似文献

Submaximal effort tolerance as a predictor of all-cause mortality in patients undergoing cardiac rehabilitation 总被引:1,自引:0,他引:1
BACKGROUND: Submaximal effort tolerance is routinely available during cardiac rehabilitation, but its prognostic value in relation to underlying referral diagnosis is not known. HYPOTHESIS: Treadmill effort capacity during submaximal exercise training predicts all-cause mortality after cardiac rehabilitation. METHODS: We followed 600 consecutive patients (450 men and 150 women, mean age 65 years) who were referred to a 12-week outpatient program of cardiac rehabilitation; 37% had a prior myocardial infarction (MI), 44% had a recent percutaneous intervention (PCI), and 39% had history of coronary artery bypass surgery (CABG). RESULTS: There were 48 deaths during a mean follow-up period of 1603 +/- 822 days. By multivariate Cox analysis, exit MET activity was the most significant predictor of all-cause mortality. In this model, each 1 MET increase in exit submaximal effort tolerance was associated with a 34% decrease in mortality (hazard ratio [HR] 0.66, 95% confidence interval 0.56-0.77) alone and 28% decrease after adjustment for age (HR = 0.72, confidence interval 0.60-0.85). Enty MET level also had predictive value. Subgroup analysis revealed that the predictive value of exit METs was limited to patients after recent CABG and with MI. None of the variables predicted death after PCI, in whom mortality was significantly lower than in the other groups. CONCLUSIONS: Submaximal effort tolerance at completion of cardiac rehabilitation, and also at entry, is a strong and age-independent predictor of mortality in patients who have had either recent CABG or MI without intervention, but not in patients after recent PCI. 相似文献

目的 探讨基础血肌酐正常的急性心肌梗死(AMI)患者直接经皮冠状动脉介入治疗(PCI)术后肾功能减退的临床特点. 方法 根据直接PCI术后是否发生肾功能减退,将216例术前血肌酐正常(<132.6 μmoL/L)的AMI患者分为肾功能减退组(32例)和非肾功能减退组(184例).比较两组的临床和冠状动脉造影资料,确定肾功能减退的发生率、预测因素及其对治疗和住院期间预后的影响.肾功能减退定义为术后72 h内血肌酐较术前升高≥25%. 结果 直接PCI术后肾功能减退的发生率为14.8%(32/216).肾功能减退组的年龄>75岁(28.1%比14.1%,P=0.047)、并发心力衰竭(25.0%比9.2%,P=0.017)的患者比例显著高于非肾功能减退组;而低分子肝素(84.4%比95.1%,P=0.039)、β-受体阻滞剂(75.0%比95.6%,P=0.001)、血管紧张素转换酶抑制剂/血管紧张素受体拮抗剂(81.3%比93.5%,P=0.025)、他汀类药物(84.4%比97.3%,P=0.008)的使用率显著低于非肾功能减退组.肾功能减退组住院期间的死亡率显著高于非肾功能减退组(25.0%比2.2%,P<0.001).多因素分析显示,并发心力衰竭是发生肾功能减退的惟一独立预测因素[比值比(OR)=3.275,95%可信区间1.275~8.408,P=0.014];而肾功能减退是住院期间死亡最强的独立预测因素(OR=10.313,95%可信区间2.569~41.402,P=0.001). 结论 基础血肌酐正常的AMI患者直接PCI术后也易发生肾功能减退.发生肾功能减退者多为AMI的高危患者,治疗不充分,住院期间预后差. 相似文献
