Medical and Surgical Emergencies and Urgencies in the Aging Patient: Geriatric Cardiovascular Emergencies Acute Chest Pain and ACS in the Elderly Patient James A. Espinosa, MD Assistant Professor, Department of Emergency Medicine UMDNJ-SOM, Stratford, New Jersey Attending Emergency Physician, Department of Emergency Medicine Kennedy Health System, Stratford Division Stratford, New Jersey Acute Chest Pain and ACS in the Elderly Patient This Care of the Aging Medical Patient in the Emergency Room (CAMPER) presentation is offered by the Department of Emergency Medicine in coordination with the New Jersey Institute for Successful Aging. This lecture series is supported by an educational grant from the Donald W. Reynolds Foundation Aging and Quality of Life program. Learning Objectives: 1) Identify geriatric aspects of the diagnosis, treatment and complications of chest pain in the elderly, including pneumonia, acute coronary syndrome, aortic dissection, and pulmonary embolism. 2) Identify potential geriatric cardiac causes of such atypical cardiac symptoms as fatigue, dyspnea, and dizziness. Introduction : • The general case for the appreciation of Geriatric Medicine finds specific importance in Geriatric Emergency Medicine! - The ED is increasingly the access point for older patients with acute medical and surgical emergencies. - The ED is increasingly the access point for older patients with chronic medical, social, or psychiatric problems. The pediatric emergency medicine movement championed the many special biological, psychological, and social needs and differences of children -differences in clinical presentation and management of children that have become core to modern knowledge base and practice. - These issues are also on point for the ED management of the elderly. What is different about the presentation and management of the elderly? What are the special issues and needs? • • Wilber, ST.

Introduction: • The emergency medicine literature is responding with discussions of the demographics, physiology, pharmacology, and psychosocial issues in elder ED care. • Central to this growing understanding is an appreciation of the way that elderly patients may present with symptoms that are atypical, in comparison to the ways that the non-elderly adult may present. • The implications of this knowledge are practical and important. Atypical presentations may be related to cognitive challenges in making the correct diagnosis -- with management, treatment and outcome implications. Such knowledge is related to patient care, risk management and patient safety. • • • • Birnbaumer DM. Rosen’s Emergency Medicine. Concepts and Clinical Practice. 2010;2348-2352. Hals G.

Question One: An 89 year old female presents to the ED from a nursing home with a history of a change in mental status and weakness. She is afebrile and does not have a history of cough or sputum production. Which of the following statements is TRUE? A. In patients >85 years of age, fever is absent in approximately 20% of cases. B. In patients >85 years of age, fever is absent in approximately 50% of cases. C. In patients >85 years of age, fever is absent in approximately 80% of cases. D. In patients >85 years of age, the presence or absence of cough, fever and sputum production are no different than in younger age groups. A Model for Atypical Presentation: Pneumonia in the Elderly • Pneumonia in the elderly may present with such atypical features (relative to younger patients) as: - Confusion/change in mental status - Increase in falls - Weakness • In patients >85 years of age, fever is absent in approximately 50% of cases. • The implication is the need for vigilance for pneumonia in the elderly in the absence of such classic features as fever, cough, and sputum production.

Rosen’s Emergency Medicine: Concepts and Clinical Practice, 7th Edition. 2010;927-938. Pneumonia in the Elderly An Example of How Process Improvement is Needed Pneumonia is the second leading reason for Medicare beneficiary hospitalization and the fifth leading cause of death among Americans greater or equal to 65 years of age. It continues to be a source of mortality and morbidity in all age groups. A study by Schuitema and Espinosa looked at the impact of a clinical algorithm for pneumonia treatment that embedded, inter alia, a change in mental status as a trigger for identification and treatment of patients with possible pneumonia. • In patients >65, there was a statistically significant reduction in door to antibiotic cycle time in patients greater or equal to 65 years of age (Preintervention average 159 min (n=225) vs. post-intervention average 116 minutes (n=158) (Student T test, p=<.01) • The percent of cases with < 4 cycle time increased from 89% to 96%. This increase was statistically significant (Chi-square, p<.01). Schuitema HS, Espinosa JA. Acad Emerg Med 2009;16(4,Suppl 1):89. Question Two: An 86 year old male presents to the ED with a chief complaint of dyspnea on exertion over a two day period. He denies chest pain. He has a past medical history of hypertension. His ECG shows non-specific ST-segment changes. A troponin is positive. Which of the following statements is FALSE? A. B. C. D. E. Myocardial infarction without chest pain is more common in the elderly than in younger patients. In patients >85, the single most common presenting symptom of coronary insufficiency “angina” is actually dyspnea, not chest pain. Elderly patients are more likely to have non-ST-segment elevation MIs than ST-segment elevation MIs. Older patients may not receive treatment for AMI that is as aggressive as younger patients. However, older patients may have less absolute benefit for such therapy and therefore less aggressive therapy is warranted. The diagnosis of AMI in the elderly is very dependent on measuring serum biomarkers. ACS/Focus on Myocardial Infarction Without Chest Pain in the Elderly • It has been established that inside the frame of unstable angina and AMI, certain subgroups are at higher risk for misdiagnosis. - Younger aged patients Diabetic patients Women Elderly • Younger patients may have classic symptoms, but MI may not be considered due to age alone (e.g., patient in early 30s with chest pain). • However, atypical symptoms seem to account for misdiagnosis in the remaining three subgroups. Kelly BS. Clin Geriatr Med 2007;23(2):327-349. Question 3: An 82 year old female presents with neck and shoulder pain associated with nausea and fatigue. The patient is diabetic. On careful questioning, a history of dyspnea on exertion of two days duration is obtained. An ECG reveals nonspecific ST-T changes and a troponin is positive. Which of the following statements is FALSE? A. Women of all ages with AMI are more likely to present with neck and shoulder pain (in the absence of chest pain) than men. B. Diabetic patients of all ages are more likely to present with clinically silent AMI, more likely to show late presentation of AMI, more likely to present with exertional dyspnea and fatigue. C. Myocardial infarction without chest pain is more common in elderly patients than in younger patients. D. Myocardial infarctions without chest pain in the elderly are less severe and have better outcomes than in presentations with chest pain. E. Anginal equivalents in elderly include: fatigue, increase in CHF, change in mental status, and syncope. ACS/Focus on Myocardial Infarction Without Chest Pain in the Elderly • ACS in women: AMI more likely to present with neck and shoulder pain than men. More likely to present with nausea and fatigue than men. • ACS in diabetics: More likely to present with clinically silent AMI. More likely to show late presentation of AMI. More likely to present with exertional dyspnea and fatigue. • ACS in elderly: Myocardial infarction without chest pain is more common than in younger patients. Kelly BS. Clin Geriatr Med 2007;23(2):327-349. ACS/Focus on Myocardial Infarction Without Chest Pain in the Elderly • Focus on ACS/AMI in elderly - In patients >85, the single most common presenting symptom of coronary insufficiency, “angina,” is actually dyspnea, not chest pain. - Patients presenting without chest pain have double the mortality of those with chest pain. - Anginal equivalents in elderly include: fatigue, increase in CHF, change in mental status, syncope.

The pathogenesis is unclear -- troponin elevations may reflect microinfarctions or may be due to left ventricular hypertrophy. Whatever the cause, such elevations track with increased mortality. • ECG interpretation can be confounded by baseline pathology. • Observation/rule out admissions remain an important element in this area.

However, older patients may have greater absolute benefit from such therapy. • In the case of thrombolytic therapy for AMI, older patients are less likely to have indications for thrombolytic therapy and are more likely to have contraindications to thrombolytics. • Suggestions for geriatric research in this area have included recommendations for studies of techniques to improve ACS recognition and treatment in the elderly as well as the inclusion of older patients in trials of ACS treatment.

Pulmonary Embolism in the Elderly • In addition to the general fund of knowledge concerning PE, there are some important key points related to PE in the elderly. These points include: - Risk for PE, having risen at age 40, rises again at age 60. The risk approximately doubles for every decade after age 60. - Much of this risk tracks with the rise in PE risk factors as a function of age, including COPD, immobility, cancer, etc. - Elderly patients may present with painless dyspnea, at rest or with exertion. Exertional dyspnea with non-specific ST-T changes may weight the differential diagnosis in the direction of AMI. - Elderly patients with PE can present with syncope (can occur at any age, especially with massive PE, but a syncope presentation for PE may be more common in the elderly).

Stein PD, Beemath A, Matta F, et al. Am J Med 2007;120(10):871-879. Pulmonary Embolism in the Elderly • Caution with physical exam in elderly patients with PE! - Rales, crackles seen in approximately 25%. Such findings would possibly lead towards a diagnosis of pneumonia. - Unilateral leg swelling or other signs of DVT are less likely with PE in elderly patients. Hals G.

Conclusions: Summary • The ED is a common point of entry to medical care for older adults. • Older patients may present with atypical symptoms of serious disease. • Several disease states have been discussed in which atypical symptoms are seen in elderly patients. • Research recommendations in elderly patients have been suggested in the literature. These include the pursuit of process improvement changes to improve outcomes, as well as continued research into diagnostic and treatment interventions to improve outcomes in ED patients with high-risk, common complaints.
