Clubbing B/P Measurement • Both arms • Orthostatic (supine, sitting, standing) 0 = absent 1 = thready 2 = normal 3 = bounding Apical heart rate • Regular, irregular, regularly irregular, irregular irregular Peripheral pulses Pupils • Size, equality, reactive Physical Exam Inspection Tracheal position Neck veins • Can guesstimate CVP Thorax • Configuration Deformities, anterior, posterior, A-P diameter, symmetrical movement Injuries, penetrating, blunt (ecchymosis, contusions) evidence of scars, surgery Abnormal chest movement, asymmetrical, paradoxical Physical Exam (Inspection) Precordium • Apical pulse • Abnormal precordial movements, heaves, lifts, pulsations, retractions • Epigastrium, pulsations Physical Exam: Palpation Areas tender, or crepitus Epigastrium Physical Exam: Auscultation Auscultatory sites • Murmurs: systolic/diastolic • Variations in rhythm • Extra sounds Pericardial friction rub Venous hum Arterial bruits • Clicks Physical Exam: Diagnostic Procedures ECG, 12 lead • Rate, rhythm • Presence of cardiac dysrhythmias • Evidence of myocardial ischemia, injury • Presence of intraventricular conduction defect • Evidence of previous MI CBC Serum electrolytes Cardiac serum markers • Troponin • Basic metabolic profile • Coagulation studies • Digoxin level • Serum creatinine, BUN • T& C • ABGs • Routine urinalysis Physical Exam: Diagnostic Procedures Interventions Determine priorities • Airway, vital signs, cardiac rhythm, ABGs, Pulse oximetry, • Control pain • Relieve anxiety • Education patient/other • Prevent complications Establish care plan Emergency equipment Initiate appropriate interventions Document data Monitor responses and adjust Geriatric Presence of chronic diseases Altered drug metabolism Multiple physiological differences and changes in lab values must be considered when assessing the older patient Psychological and social changes: patient may have different goals for their treatment, discuss with patient Geriatric patients can adapt to disease so well that symptoms are not obvious Arteriosclerotic changes in aorta and peripheral pulses may pose a difficulty in palpating Rhythm abnormalities are so common that they may be “normal” Pearls “Go slow, stay low” with medications Concurrent use of other medications cause problems, • Easy to use meds are helpful (transdermals) • One time or two time doses daily • Evaluate medications on a frequent basis Angina Stable • Symptom of ischemia • “pain or discomfort” • Poorly localized • Flow/Demand imbalance • May be chronic, acute, or unstable Angina (continued) Unstable angina • New symptoms of angina • Increasing symptoms that occur at rest or with on exertion • Usually due to platelet aggregation • Leads to atypical chest pain Angina (Continued) Unstable angina diagnosis • Angina is at rest, as well as minimal exertion (usually 20 minutes or longer) • Angina of new onset (several weeks), starting with physical exertion, and markedly limits activity • Previously diagnosed stable angina Normal ECG Abnormal ECG Same Patient, Inverted T Waves Angina cont’d Variant Angina • May or may not be due to atherotic changes • Thought to be due to coronary spasm • Prinzmetal’s angina • May occur at the same time, daily • Usually not associated with exertion or stress • Occurs at younger ages • ST elevation seen during pain, then disappears Angina: Curveballs GERDs Biliary Colic Chest Wall Pain Pericarditis PE Aortic Dissection Dysrhythmias Angina: Data Physical exam: • • • • • Elevated B/P Increased Heart Rate Rapid, shallow respirations Diaphoresis Transient pulmonary rales (with pain) Diagnostic Procedures: ECG ST depression may accompany pain with stable angina Transient ST-segment deviations (depression or elevation), and T wave inversion occur commonly with unstable angina Variant angina: ST elevation occurs with pain, subsides when pain does May see LV hypertrophy, old MI, nonspecific ST and T-wave abnormalities and AV defects Diagnostic Procedures (Continued) CBC Cardiac serum markers…no elevation should occur unless cell damage Chest X-ray ( CHF, cardiomegaly) Interventions Continuous monitoring O2 IV, Draw labs 12 Lead ECG Rest Decrease anxiety SL NTG, B/P 100 mm HG followed by a drip • Assess for H/A • Reflex tachycardia • Cautious with elderly Interventions (continued) Beta blockers • If clinical situation deteriorates after B Blocker, consider coronary artery spasm • Assess for signs of heart failure • Adverse effects of blockers are considered more common and severe in geriatric Interventions (continued) Administer antiplatelet agents • ASA (4-5 baby aspirin) • Administer ASAP • Decreases platelet activation and thrombus formation TEACH/EDUCATION Acute Myocardial Infarction Myocardial Infarction (MI)Coronary Occlusion Heart Attack MI: Data Physical exam General appearance: Anxious, restless, clenched fist against chest (Levine sign) Look of doom Heart rate: may be ok, tachycardia (most common), bradycardia (inferior and RV), Regular or irregular PVCs common Data (continued) Arterial BP • Majority of patients with uncomplicated MI are normotensive • May be elevated due to SNS stimulation Pain and anxiety • Decreased as a result of impaired cardiac function or due to drug administration (nitrates, M.S.) Data (continued) Respiratory rate: Initially elevated. Should return to normal after pain relief • Patients with CHF, respiratory rate correlates with severity of condition Data (continued) Peripheral: How bad is the patient’s condition? • Pallor, cyanosis, diaphoreses, mottled, cool, peripheral pulses variable Temperature: Often increases 4-8 hours post MI Heart Sounds: muffled. murmurs may be transient or permanent Diagnosis Continuous cardiac monitoring 12 lead ECG Determine Location of infarct (next slide) Anterior Septal ST Leads 1, AVR, V1 through V4 Lateral Apical ST Leads 1, AVL V5 and V6 Posterior Recipical Changes V1,V2 No Q waves, Tall R’s St II,III,AVF Upright t wave ST Leads II, III, AVF Inferior Serum Markers (continued) Troponins: • Most recent marker, most sensitive and specific for cardiac damage • Elevated 3-12 hours after MI, Peaks in 24 hours, with TnI , returns to normal in 5-12 days • TnT may be elevated in patients with renal failure, which is not the case with TnI; therefore TnI is utilized. Interventions ABCs Oxygen IV or topical NTG, as B/P tolerated (B/P 100 or greater IV with normal saline, KVO Analgesia: M/S ASA 12 Lead ECG Blood samples for analysis Interventions (continued) If appropriate consider PTCA Follow ACLS Guidelines Prepare for Thrombolytic Therapy as appropriate Administer aspirin, nitrates, heparin, plavix, Integrillin, Lopressor, Morphine, antiarrhythmics Interventions (continued) Observe patient: • Bleeding, reperfusions dysrhythmias • Vital signs, ventricular ectopy, and other dysrhythmias • Heart and lung sounds • LOC Interventions (continued) Portable chest film ACLS measures Prepare for cath lab Educate and explain Allow visit from significant other Heart Failure & Cardiogenic Pulmonary Edema Clinical syndrome, can occur from any heart disease Pediatric..usually due to congenital heart defects Inability to discharge contents Inability to pump enough blood to meet metabolic needs Vasodilators (continued) NTG, Isosorbide • Increases venous pooling • NTG preferred in pulmonary edema, CAD since improves coronary artery perfusion • Venous dilation Vasodilators (continued) Diuretics: • Decrease preload • Foley catheter, possible • I&O • Monitor serum K+ Vasodilators (continued) ACE Inhibitors: • Captopril, Enalapril • Block formation of Angiotensin II, yields vasodilation • Reduce mortality, by improving cardiac function • Avoid overdiuresis • Cleared by kidney Inotropes Dopamine • Support B/P and UO • Dopaminergic effect: 1-2 mcg/kg/min • Beta-adrenergic: 2-10 mcg.kg/min • Alpha-adrenergic >10mcg/kg/min • Indicated for low cardiac output • Infuse in central line or large vein Dobutamine • Stimulates beta receptors in heart • Direct inotrope • No renal benefit • Indicated: low cardiac output • Can decrease B/P in volume depleted patients
