    Flashcards

    Acute Coronary Syndrome (ACS)

    A disorder that affects the heart due to reduced blood flow to the heart muscle, leading to symptoms like chest pain or discomfort, shortness of breath, and fatigue.

    Risk Factors for Coronary Artery Disease

    Factors that increase the risk of developing coronary artery disease. They can be categorized as modifiable, meaning they can be changed through lifestyle choices, and non-modifiable, meaning they are beyond an individual's control.

    Modifiable Risk Factors

    Factors that can be altered through lifestyle changes, such as diet, exercise, and smoking cessation. These factors can be influenced by an individual's choices and action.

    Non-Modifiable Risk Factors

    Characteristics that are primarily genetically determined and cannot be easily changed. These include age, sex, family history, and genetic predisposition.

    Asymptomatic Coronary Artery Disease (CAD)

    A condition where the coronary arteries are narrowed or blocked, but the individual experiences no symptoms. This is often detected during routine check-ups or when investigating other medical conditions.

    Stable Angina

    Chest pain that occurs during physical exertion or activity and is predictable. It usually occurs when the heart needs more oxygen during activity due to narrowed arteries.

    Study Notes

    Acute Coronary Syndrome

    • Risk Factors for Coronary Artery Disease:
      • Non-modifiable: age, sex, family history, genetics
      • Modifiable: smoking, diet, alcohol, physical activity, dyslipidemias, hypertension, obesity, diabetes, metabolic syndrome
    • Spectrum of Ischemic Heart Disease:
      • Asymptomatic coronary artery disease (CAD)
      • Stable angina (predictable chest pain with activity)
      • Acute Coronary Syndrome (due to platelet-mediated thrombosis, sudden cardiac death)
    • Types of Acute Coronary Syndrome:
      • Unstable angina
        • Chest pain at rest, unpredictable, may be relieved by nitroglycerin, troponin negative, ST depression, or T-wave inversion on ECG
      • Non-ST Elevation Myocardial Infarction (NSTEMI)
        • Troponin positive, ST depression, T-wave inversion on ECG, unrelenting chest pain
      • ST Elevation Myocardial Infarction (STEMI)
        • Troponin positive, ST elevation in 2 or more contiguous leads, unrelenting chest pain
      • Variant/Prinzmetal's Angina
        • Type of unstable angina associated with transient ST segment elevation, due to spasm with or without atherosclerosis
    • Management of Acute Chest Pain:
      • Stat ECG, read within 10 minutes for categorization (STEMI, NSTEMI/unstable angina, no acute change)
      • Risk stratification (high, medium, low)
      • Aspirin (chewed ASAP, improves morbidity and mortality)
      • Anticoagulants (heparin or enoxaparin)

    Additional Treatments and Diagnostics

    • Antiplatelet Agents: heparin/enoxaparin, clopidogrel, abciximab, eptifibatide, tirofiban
    • Beta Blockers: cardioselective (metoprolol) preferred; avoid non-selective (propranolol) in certain cases
    • Pain Treatment: nitroglycerin, morphine
    • Lab Assessment: cardiac biomarkers, lipid profiles, CBC, electrolytes, BUN, creatinine, magnesium, PT, PTT
    • ECG Lead Changes: associated changes reflecting different coronary artery involvement (e.g., changes in II, III, aVF indicate right coronary artery; changes in V1-V4 indicate left anterior descending)
    • Differentiation of MI Types: inferior MI, lateral MI, anterior MI (based on ECG changes, associated symptoms, etc.)

    Further Details of MI types and Treatment

    • Inferior MI: ST elevation in II, III, aVF; associated with right coronary artery occlusion; may have symptoms of JVD, high CVP, hypotension, clear lungs, bradyarrhythmias; may have right ventricular involvement
    • Anterior MI: ST elevation in V1-V4; associated with left anterior descending occlusion; may have systolic murmur (mitral valve regurgitation or ventricular septal defect); higher mortality than inferior MI
    • Lateral MI: ST elevation in V5, V6, I, aVL; associated with left circumflex occlusion
    • Reperfusion Strategy: PCI (within 90 minutes of symptom onset) for STEMI; fibrinolytic therapy (within 30 minutes) in appropriate cases for STEMI.
    • Complications: arrhythmias (ventricular tachycardia/fibrillation), heart failure, cardiogenic shock, reinfarction, thromboembolic events, pericarditis, ventricular aneurysm, ventricular septal defect, papillary muscle rupture, cardiac wall rupture.
    • Nursing Management: assess for major and minor bleeding, changes in LOC, brain bleed, institute bleeding precautions, assess for repurfusion, assess for reocclusion as evidenced by recurring chest pain and ST deviation for STEMI and NSTEMI patients; monitor for possible vasovagal reactions, hypotension, and bradycardia.
    • Treatment of NSTEMI: similar medications as STEMI, high-risk patients/continued chest pain warrants diagnostic cardiac catheterization; use of GP IIb/IIIa inhibitors as appropriate.
    • Additional NSTEMI Notes: possibility of high risk score or continued chest pain prompting diagnostic cardiac catheterization if patient is considered at high risk.
    • Monitoring for Bleeding: Hemostasis (pressure applied for at least 20 minutes, 30 if GP IIb/IIIa inhibitors administered) after procedure. Possible monitoring for retroperitoneal bleeding (fluid or blood products should be given as needed).

    Additional Notes (Page 4 and 5)

    • Chest Pain Management: nitroglycerin, PCI, possible need for vasovagal reaction management (fluids, atropine), monitor for bleeding, specific details like door-to-balloon (PCI) < 90 minutes for STEMI are included, monitoring for bleeding (manual pressure on puncture site for 20-30 minutes); avoiding preload reducers (like nitrates, diuretics) in anterior MI due to potential hypotension; potentially using inotropic support.
    • Absolute Contraindications for Fibrinolytic Therapy: prior intracranial hemorrhage, structural cerebral vascular lesion, known malignant intracranial neoplasm, stroke within 3 months (except acute ischemic stroke within 3 hours), suspected aortic dissection, active bleeding, bleeding diathesis (excluding menses); careful consideration required for patients with ischemic stroke within 3 months (except acute ischemic stroke).
    • Repurfusion Arrhythmias: ventricular tachycardia (VT), ventricular fibrillation (VF), and Accelerated Idioventricular Rhythm.
    • Nursing Management (Reperfusion): assess for major and minor bleeding, changes in LOC, brain bleed, institute bleeding precautions, assess for repurfusion, assess for reocclusion as evidenced by recurring chest pain and ST deviation; need to assess for potential repurfusion arrhythmias.
    • Additional Considerations for Nursing Care: Monitor for signs of reocclusion (chest pain, ST elevation), vasovagal reactions (requiring fluids or atropine), hypotension(<90 systolic), bradycardia, or absence of compensatory tachycardia.
    • Specific details included: Door-to-Balloon (PCI) < 90 minutes for STEMI, Monitoring for bleeding (manual pressure on puncture site for 20-30 minutes).
    • Additional possible complications: Bradycardia, heart blocks, sick sinus syndrome, higher risk of mortality if return to NSR is complicated by arrhythmias. Potential for thromboembolic events, pericarditis, ventricular aneurysm, ventricular septal defect, papillary muscle rupture, cardiac wall rupture, reinfarction.
    • Additional Notes: Use of beta blockers needs careful consideration in anterior MIs due to potential for hypotension (consider inotropic support). Possible 2nd degree Type II AV block or RBBB development. May develop ventricular septal defect.
