Broken Heart Syndrome Jeff Wager CRNA Jeff Burnette MD John Olayer CRNA Outline • Case study • Description – Takotsubo Cardiomyopathy – Acute Coronary Syndrome – AHA journal article • Discussion Something’s Not Right • You may never see this syndrome • Most patients do what they are supposed to. • Application in your practice setting • Don’t take my sarcasm personally Vigilance vs. Complacence Vigilance • Safe Passage- who else is going to do it? • Anyone could be trained to do the tasks • Crucial job of the nurse is the timely recognition of trouble and calling the Calvary • Broken heart is what you will have if the opportunity to prevent a bad outcome is missed. Is This Patient Okay • Most people can tell if someone is actively dying • The middle of the continuum is difficult • Less experienced nurses need guidance and mentoring • Chicken Little and Cliff Clavin • Rarely will everything have an explanation many things don’t need one Complacence • Most patients do fine • Production pressure • My job is just to get them transferred to the next place • Discontinuous care • Burn out • Not my problem • Extremely annoying patients Anxiety and Discretion • Patients are inherently anxious. • We should strive to reduce this as much as is ethically possible. • Inappropriate sharing of our “insider knowledge” has the potential to scare people away from seeking the healthcare that they need. • The media and trial lawyers don’t need our help frightening patients. Case Study • 46 year old AAF presenting with pelvic pain • Scheduled for hysteroscopy and diagnostic laparoscopy • Past Medical History – Hypertension – Vertigo – Heme positive stool Pre-op Evaluation • Overall unremarkable • Slightly strange collection of symptoms – Pelvic pain – Heme positive stool- colonoscopy scheduled following week – Vertigo Induction of Anesthesia • Premedicated with versed immed prior to transport to OR • Routine IV induction and intubation • Post intubation hypertension and tachycardia-slightly more than average • 180-190/100-110 and Hr to 120 • Immed treated with esmolol then lopressor • Htn and tachycardia resolved Uneventful Case • • • • Hemodynamically stable No problems with ventilation/oxygenation Easily extubated ?? Relative hypoxemia-quick desaturation without oxygen mask • Transport to pacu • Someone else’s problem Is This patient Okay • Sao2 in pacu upper 80’s- low 90’s on 4 liters O2 NC • PCXR- ? Bilateral infiltrates vs pulmonary edema • Breath sounds were clear • Incentive spirometry initiated • Still O2 dependent- admitted for observation Differential Diagnosis • Blame Anesthesia- Is she awake, residual weakness from muscle relaxation, iatrogenic fluid overload, atelectasis, aspiration • Patient history predicts increased O2 requirements post op- preexisting pulm dz? • Narcosis-common problems are common • Could her procedure be responsible – Splinting from pain – Lung surgery Zebras • • • • • Uncommon problems do exist Pulmonary embolism Negative pressure pulmonary edema Diffusion atelectasis And 1,000,000 other things you may never have heard of This Patient is not Okay • Chest pain and shortness of breath after admission to floor • Abnormal EKG • When you hear hooves • Positive cardiac enzymes • Echocardiogram-hypokinesis of anterior wall with EF 40-45% Acute Coronary Syndrome • • • • Heparin and nitroglycerin started Straight to cath lab for angiography and ? Coronary arteries were normal Diagnosed with Takotsubo cardiomyopathy with surgery being the causative stressor. Takotsubo Cardiomyopathy • Stress induced cardiomyopathy • Apical ballooning cardiomyopathy • Transient left ventricular apical ballooning syndrome • Discovered in Japan and named for octopus trap with similar shape to apically ballooning heart. • Caused by emotional or physical stress Other Zebras • • • • Prinzmetals angina Myocarditis Cocaine abuse Cardiac syndrome X Demographics • Postmenopausal women make up 70-80% • May account for 2% of ACS presentations • Prospective MICU study non cardiac pts 26 out of 92 had ballooning. • Case Studies – Oxycontin withdrawal after admission for surgery – Pre-op anxiety caught in OR before case – Clinical doses of adrenergic agents Stressors • • • • • • • Any significant physical or emotional event Death of a loved one Financial or legal problems Natural or man made disasters Near drowning Critical illness Tigers or Gamecocks Mayo Clinic Diagnostic Criteria • Transient hypokinesis, akinesis, of dyskinesis of the left ventricle mid segments with or without apical involvement. Wall dysfunction usually extends beyond a single coronary artery distribution. Stressful trigger usually present. • No obstructive cad or plaque rupture Mayo Clinic Diagnostic Criteria • New St elevation or T wave inversion or modest increase in troponin • Absence of pheochromocytoma or myocarditis. • All four required Presentation • • • • • • • Substernal chest pain Dyspnea-pulmonary edema Syncope Shock-mitral regurg-LV outflow obstruction Ekg changes anterior leads Lethal arrhythmias Thrombus-stroke Treatment • Per severity of symptoms • Same as regular LV systolic dysfunction – Afterload reduction-ACE inhibitors – Arrhythmia prevention-beta blockers – Diuresis – ? Anti-coagulation – Shock requires immed echo to r/o LVOT – Long term adrenergic blockade to prevent reoccurrence Prognosis • Systolic function usually recovers in 1-4 weeks with supportive therapy • Mortality 0-8% • Deaths usually from arrhythmias Pathophysiology • Several theories – Multivessel coronary artery spasm – Cardiac microvasular dysfunction – Altered fatty acid metabolism – Catecholamine toxicity with stunning and microinfarction Not Pumping Enough • Inadequate forward flow • Anything downstream of the aortic valve doesn’t get enough • Upstream of left ventricle gets too much Acute Coronary Syndrome • Retrosternal chest pain – Pressure or tightness – Radiates to shoulders, neck arms, jaw, back or between shoulder blades – Syncope, dizzy/lightheaded, nausea, sweating – Unexplained shortness of breath Why does their chest hurt • The supply of oxygen to the heart is less than the demand. • A resting heart extracts 75% of oxygen delivered by coronary blood flow. • Pain is a warning that heart cells are about to start dying time is short • Restoration of balance between supply and demand is essential to save as much muscle as possible Talk or Treat • Acute coronary syndrome presentation should be treated as such until definitively proven otherwise • Send Clavin to lunch • MONA • 12 Lead EKG • Cardiology consult-immed expert help Circulation Article • Journal of the American Heart Association • Published Jan 9 2012 • “Grief over the death of a significant person was associated with an acutely increased risk of MI in the subsequent days.” • Rate of acute MI increased 20 times within 24 of learning of significant death and remains elevated for one month. Grief MI Risk • Men more than women • Younger more than older • Increased with severity of loss Talk and Treat • Authors suggest providing social support at time of bereavement • Education • Authors also suggest the possibility of prophylactic agents for homodynamic and thrombotic events
