In a consecutive series of 2312 patients with acute myocardial infarction (AMI) admitted from 1973 till 1979, 188 were 80 years or older (group III). They were compared with 1167 patients younger than 65 years (group I) and 957 aged 65 to 79 years (group II). The sex ratio (males/females) fell from 5.46 in group I to 0.9 in group III. Group III patients had more frequently a history of previous heart failure and more often atypical or no chest pain before admission. Less group III patients were admitted within 4 hours after onset of symptoms, but the incidence of heart failure, pulmonary edema and cardiogenic shock on admission and during CCU stay was definitely higher than in younger patients. Atrial arrhythmias, 2nd and 3rd degree atrioventricular block, complete bundle branch block and intraventricular conduction disturbances occurred more frequently in group III. The electrocardiographic extent and location of the infarction and peak enzyme levels were similar in the three groups. Mortality in group III was 43.6% at the 28th day and 76.6% at one year after AMI. At different intervals after the onset of AMI mortality increased progressively from group I to III. Age by itself, probably on the basis of definite structural changes of the heart and of other organs occurring during aging, leads to higher early and late mortality in very elderly people. 相似文献

OBJECTIVE: Diabetes mellitus (DM) has been associated with an elevated, short-term risk of death after myocardial infarction (MI). Among the studies of DM, however, few studies have included elderly subjects. The purpose of the present investigation was to determine if non-insulin-treated DM (NIRxDM) and insulin-treated DM (IRxDM) were associated with specific comorbid conditions, clinical findings on arrival, and MI characteristics, as well as a higher 30-day mortality rate in elderly patients with acute MI. DESIGN: The study design was a retrospective medical record review and secondary data analysis of previously collected data from the Cooperative Cardiovascular Project. SETTING: Study setting was Connecticut from June 1, 1992, through February 28, 1993. PATIENTS: Subjects included the entire Medicare population (n = 2050), aged 65 years or older who were hospitalized for acute MI. OUTCOME MEASURES: Mortality rate at 30 days after MI was measured. RESULTS: A history of DM was observed in 29% of the study population. DM status was associated with previous comorbid conditions, poorer functional status, higher body mass index, heart failure on arrival, non-Q-wave MI, and development of atrial fibrillation and oliguria during hospitalization. Patients with DM were less likely to have chest pain on arrival to the hospital. Diabetic status was not a significant predictor of short-term mortality; at 30 days after MI, 17% (n = 242) of the subjects without DM, 19% (n = 71) of those with NIRxDM, and 18% (n = 39) of the subjects with IRxDM died (P = .460). After adjustment for other prognostic factors, it was noted that MI characteristics present on hospital arrival predicted mortality at 30 days in both patients with NIRxDM and patients with IRxDM. CONCLUSIONS: The slightly, but not significantly, increased mortality risk in patients with DM should not minimize the importance of monitoring DM in the acute MI setting. Hospitalization for MI provides an opportunity to provide aggressive lipid and blood pressure management, optimize blood glucose, control heart failure, and institute other secondary preventive interventions in the elderly population with DM. 相似文献

Cardiovascular disease is the most common cause of death in the elderly. In fact, the cardiovascular disease is the number one cause of death in women and the number two cause in men of 65 years or over in Japan. We studied the clinical characteristics and significances of acute myocardial infarction as they relate to the aged. 相似文献

Background: Primary percutaneous coronary intervention (PPCI) is the choice reperfusion strategy for acute ST‐segment elevation myocardial infarction (STEMI). However, data on PPCI in elderly patients are sparse. This study determined clinical outcome post‐PPCI in elderly versus younger patients with STEMI. Methods and Results: A cohort of 790 consecutive STEMI patients was studied for survival and major adverse cardiovascular events (MACE) after PPCI using a precise cardiac catheterization protocol. Patients were divided into two groups: those ≥75 years (elderly) and those <75 years. Median door‐to‐balloon time (DBT) was 82 minutes in the elderly versus 66 minutes in the younger group (P = 0.002). In‐hospital all‐cause mortality was higher in the elderly group (15.5% vs. 2.7%, P < 0.001). In elderly patients, MACE were found to be higher (32.3% vs. 16.1%, P < 0.001). Using a multivariate logistic regression analysis, age (odds ratio [OR]= 1.04, 95% confidence interval [CI]= 1.02–1.05, P < 0.001), diabetes (OR = 2.17, 95% CI = 1.33–3.53, P = 0.002), renal failure (OR = 3.75, 95% CI = 1.30–10.79, P = 0.014) and coronary artery disease (OR = 1.61, 95% CI = 1.00–2.59, P = 0.050) were associated with higher in‐hospital MACE, while age (OR = 1.05, 95% CI = 1.02–1.08, P = 0.001), diabetes (OR = 2.18, 95% CI = 1.06–4.47, P = 0.034) and renal failure (OR = 6.65, 95% CI = 2.01–22.09, P = 0.002) were associated with higher in‐hospital mortality. Kaplan–Meier 1‐year survival rate was lower in the elderly. Conclusions: In a contemporary population of STEMI patients treated with PPCI, overall in‐hospital MACE and mortality remain higher in elderly compared to younger patients. Although partly due to higher burden of preexisting comorbidities, a higher DBT may also be responsible. (J Interven Cardiol 2011;24:357–365) 相似文献

The in-hospital management and risk of death of 101 patients 70 years of age or older with acute myocardial infarction in 1987 (group 1) were compared with management and risk for 106 temporally matched patients less than 70 years old (group 2). In group 1, 49% had histories of previous myocardial infarction, compared to 25% in group 2 (P less than 0.001), and 23% of group 1 presented without cardiac pain, versus 7% of group 2 (P less than 0.001). Among the younger patients, other conventional risk factors were, in contrast, more common (Q wave infarction 84% in group 2 versus 70% in group 1; P less than 0.05) or higher (peak creatine kinase values 2222 iu/L in group 2 versus 1366 iu/L in group 1; P less than 0.001). Prior to infarction, all cardiac drugs were used more frequently in the older group 1 patients, whereas post infarction thrombolysis, beta-blockers and acetylsalicylic acid use were all more common (P less than 0.01 to P less than 0.001) in the younger group 2 patients. Post infarction exercise testing, left ventricular ejection fraction calculations and coronary angiography were all performed less frequently in group 1 (P less than 0.001). The in-hospital mortality was 35% for group 1 versus 7% for group 2 (P less than 0.001). Among all 207 study subjects, multiple logistic regression revealed thrombolysis, absence of cardiac pain, and age 70 years or older to be associated with the greatest relative mortality risk. Increased relative risk to a lesser degree was associated with previous infarction, male sex and post infarction use of antiarrhythmic medication.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Acute myocardial infarction (AMI) in pregnancy is associated with high morbidity and mortality. Management of these patients can be challenging as little is known about the optimal management strategy. Medications routinely used may have harmful effects on the pregnancy outcome. In addition, AMI could occur in the absence of atherosclerotic disease. We describe optimal management strategy by eliciting the management of a 45-year-old female with ST segment elevation myocardial infarction. We recommend early use of coronary angiography to define the pathology in such cases. Radial artery assess should be preferred. Pregnant patients with AMI due to atherosclerotic disease should be given a 325 mg of aspirin and 600 mg of clopidogrel and either balloon angioplasty or bare metal stent should be used for revascularization. Percutaneous coronary intervention with heparin is preferred over bivalirudin and later should be reserved for patients with severe heparin allergy. 相似文献

OBJECTIVES: We evaluated the clinical characteristics and outcomes of elderly patients hospitalized with acute myocardial infarction (AMI) to describe differences by age. BACKGROUND: Elderly patients with AMI are perceived as a homogeneous population, though the extent by which clinical characteristics vary among elderly patients has not been well described. METHODS: Data from 163,140 hospital admissions of Medicare beneficiaries age > or =65 years between 1994 and 1996 with AMI at U.S. hospitals were evaluated for differences in clinical characteristics and mortality across five age-based strata (in years): 65 to 69, 70 to 74, 75 to 79, 80 to 84 and > or =85. RESULTS: Older age was associated with a greater proportion of patients with functional limitations, heart failure, prior coronary disease and renal insufficiency and a lower proportion of male and diabetic patients. Of note, the proportion of patients presenting with chest pain within 6 h of symptom onset, and with ST-segment elevation, was lower in each successive age group. Thirty-day mortality rates were higher in older age groups (65 to 69: 10.9%, 70 to 74: 14.1%, 75 to 79: 18.5%, 80 to 84: 23.2%, > or =85: 31.2%, p = 0.001 for trend). The effect of age persisted but was attenuated after adjustment for differences in patient characteristics; similar trends were observed for one-year mortality. CONCLUSIONS: Our data indicate significant age-associated differences in clinical characteristics in elderly patients with AMI, which account for some of the age-associated differences in mortality. The practice of grouping older patients together as a single age group may obscure important age-associated differences. 相似文献
