Acute myocardial infarction in the elderly: differences by age
Journal of the American College of Cardiology, 2001
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.
Comparison of Patients with Acute Myocardial Infarction According to Age
Medicinski arhiv, 2019
Introduction: By development of the medicine, control of the risk factors for acute myocardial infarction (AMI), became the foundation of cardiology. Aim: To investigate the association of the age with presence of risk factors in patients with acute myocardial infarction. Methods: The study had a prospective, comparative and descriptive character, and it was done on a sample of 80 patients (n=80; 55 male and 25 female) Clinic for Heart, Blood Vessel and Rheumatic Diseases, Clinical Center University of Sarajevo from January 2016 to August 2018. All patients were hospitalized under the diagnosis of myocardial infarction and were divided into two main groups, which were divided into two subgroups according to age. Group A, group of patients under 45 years of age at the moment of diagnosis of AMI (n = 40; men = 29; women = 11) was divided into group A1 (n = 20; patients aged 25-35 years) and group A2 (n = 20; patients aged between 35-45 years). Group B, patients older than 45 years at the time of diagnosis of AMI (n = 40; men = 26, women = 14) was divided into group B1 (n = 20; patients aged between 45-55 years) and group B2 (n = 20; patients aged 55-65 years of age). Results: According to gender distribution, there is a significantly higher incidence of hypertension in male patients aged 25-35 years and between 35-45 years (p = 0.01; p = 0.01). Increased cholesterol values were significantly more common in men aged 25-35 years (p = 0.0121). Increased triglyceride values were significantly more common in men aged 25-35 years, in comparison to female respondents of the same age (86.67% vs. 13.33%, p = 0.0001). There was a significant significance between the two groups in the occurrence of anteroseptal (p = 0.04) and in the diaphragmatic myocardial infarction (p = 0.01), while in other infarction localities no significant significance was observed. Conclusion: Male sex is a predisposing risk factor for the development of a cardiovascular incident in the younger age. The post infarction ejection fraction of the left ventricle was significantly reduced in younger patients. The potential for prevention should be of paramount importance. The localization of the incident itself, and the involvement of a certain blood, represents, regardless of all the research, still a fact that is hard to stratify and directly correlated with a certain risk factor.

Older age is known as a negative prognostic parameter in patients with acute myocardial infarction (AMI). In this study, we aimed to investigate age-related differences in treatment protocols, in-hospital and 1-year mortality. This retrospective observational single-center study enrolled consecutive AMI patients with an urgent percutaneous coronary intervention (PCI) as the main method of myocardial revascularization. The patients divided were divided by age into group I (≥65 years) and group II (<65 years). The primary endpoint was in-hospital mortality, the secondary endpoints were 1-year mortality and rehospitalization rates. Of the 522 admitted with AMI, 476 were enrolled in the study. The mean age was 67 ± 13 years; 62% were men. Group I patients had a significantly lower rate of performed PCI (65% vs. 79%, P < 0.001). 53 patients (12.3%) died during hospitalization, and this proportion was notably higher in the older population (20% vs. 6%, P < 0.0001). The cardiac causes of death were more frequent in group I patients (12% vs. 5.6%, P = 0.016). The multivariate logistic regression selected two variables as independent predictors for the risk of in-hospital death: age ≥65 years (P = 0.0170), and Killip class at admission (P < 0.0001). The 1-year mortality was 3.3%, slightly higher in group I patients (4.8% vs. 1.5%, P = 0.05). In conclusion, patients aged ≥65 years have three times higher in-hospital mortality, but similar 1-year mortality and readmission rates when compared with the younger patients. It is obvious that there is a large potential for improvement of the AMI care in this age group of patients.
The Clinical Manifestation of Myocardial Infarction in Elderly Patients
Clinical Cardiology, 2009
Background and HypothesisThe study aimed to compare the clinical picture and treatment differences in elderly patients (aged 75 years or older) and younger patients (aged below 75 years).The study aimed to compare the clinical picture and treatment differences in elderly patients (aged 75 years or older) and younger patients (aged below 75 years).MethodsThe study included 80 consecutive patients with myocardial infarction (MI) treated in the Cardiology Ward of the Specialist Hospital in Radom, Poland, in 2005. Analyses were performed retrospectively. The patients were separated into 2 groups according to age. The group I study group consisted of 40 patients aged 75 or over (aged 75–95; mean 81 years) and the group II control group consisted of 40 patients aged below 75 years (aged 42–67; mean 60 years).The study included 80 consecutive patients with myocardial infarction (MI) treated in the Cardiology Ward of the Specialist Hospital in Radom, Poland, in 2005.

ST-segment elevation myocardial infarction (STEMI) was also more common (p<0.05). Non-ST-segment elevation myocardial infarction (NSTEMI) was more frequently diagnosed in the elderly (p<0.05). In elderly patients there were more women (p<0.05), more patients with previously diagnosed ischemic heart disease (p<0.05), with hypertension (p<0.05), and with diabetes mellitus (p<0.05). Obesity was less frequently diagnosed in the elderly; however the difference was not statistically significant. Dyslipidemia and cigarette smoking were both significantly less common among elderly patients (p<0.05). The elderly were significantly less frequently revascularized (p<0.05). Both fibrinolysis and primary percutaneous coronary intervention (PCI) were less commonly applied to the elderly (p<0.05). Time from symptom onset to hospital admission was significantly longer in the case of elderly patients (p<0.05). The MI complications and side effects of treatment seemed to be more frequent in the elderly, but only post-MI heart failure was observed more frequently in this group of patients (p<0.05).In the elderly, as compared with younger subjects, dyspnea, fatigue, and other heart failure symptoms, were more frequently the first symptoms of MI than typical chest pain (p<0.05).

Age and clinical outcomes in patients presenting with acute coronary syndromes
Journal of cardiovascular disease research, 2013
Context: Elderly patients have more cardiovascular risk factors and a greater burden of ischemic disease than younger patients. Aims: To examine the impact of age on clinical presentation and outcomes in patients presenting with acute coronary syndrome (ACS). Methods and material: Collected data from the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2), which is a prospective multicenter study from six adjacent Arab Middle Eastern Gulf countries. Patients were divided into 3 groups according to their age: 50 years, 51e70 years and >70 years and their clinical characteristics and outcomes were analyzed. Mortality was assessed at one and 12 months. Statistical analysis used: One-way ANOVA test for continuous variables, Pearson chi-square (X 2 ) test for categorical variables and multivariate logistic regression analysis for predictors were performed. Results: Among 7930 consecutive ACS patients; 2755 (35%) were 50 years, 4110 (52%) were 51e70 years and 1065 (13%) >70 years old. The proportion of women increased with increasing age (13% among patients 50 years to 31% among patients > 70 years). The risk factor pattern varied with age; younger patients were more often obese, smokers and had a positive family history of CAD, whereas older patients more likely to have diabetes mellitus, hypertension, and dyslipidemia. Advancing age was associated with under-treatment evidence-based therapies. Multivariate logistic regression analysis after adjusting for relevant covariates showed that old age was independent predictors for re-ischemia (OR 1.29; 95% CI 1.03e1.60), heart failure (OR 2.8; 95% CI 2.17e3.52) and major bleeding (OR 4.02; 95% CI 1.37 e11.77) and in-hospital mortality (age 51e70: OR 2.67; 95% CI 1.86e3.85, and age >70: OR 4.71; 95% CI 3.11e7.14). Conclusion: Despite being higher risk group, elderly are less likely to receive evidence-based therapies and had worse outcomes. Guidelines adherence is highly recommended in elderly.

To study the in-hospital evolution of patients aged 65 years and older, with acute myocardial infarction, who were treated by direct coronary angioplasty with no fibrinolytic therapy. Methods-We studied 885 patients divided into 2 groups as follows: group I (GI)-293 (33.4%) patients aged ≥ 65 years (72±5 years), and group II (GII)-592 patients aged < 65 years (57±9 years). Multivessel disease was more frequent in GI (63.5% x 49.7%; p=0.001). A greater number of GII patients were class I or II of the clinical Killip-Kimball classification (K) (80.2% x 67.2%; p=0.00002), while a significant number of GI patients were KIII and KIV (24.3% x 12.8%; p=0.00003). Results-Group I had a lower index of success (84.6% x 94%; p=0.0002) and a greater in-hospital mortality (12.2% x 4.7%; p=0.00007). The predictors of mortality in GI were as follows: previous infarction (20.5% x 6.3%; p=0.02), anterior location (13.4% x 6.4%; p=0.03), and male sex (10.4% x 4.4%; p=0.007). Conclusion-Elderly patients had more severe acute myocardial infarction and more extensive disease, a lower index of success, and greater in-hospital mortality. Previous infarction, anterior location and male sex were identified as predictors of mortality in the elderly group (GI).
