Overview

The transcript covers key nursing concepts related to acute coronary syndrome, myocardial infarction (MI), and the management of patients requiring reperfusion therapy.

Key Concepts

Reperfusion Therapy

  • Definition and Importance: Reperfusion therapy is utilized predominantly for ST-Elevation Myocardial Infarction (STEMI).

  • Use of tPA (Tissue Plasminogen Activator):

    • TPA is specific to STEMI cases.

    • It is a dangerous drug and requires careful monitoring.

    • Indications for Use:

    • Must be administered within 12 hours of the onset of chest pain.

    • Requires confirmation via EKG that the patient is experiencing STEMI.

NCLEX Strategies

  • Select All That Apply (SATA) Question Format:

    • May contain multiple options (e.g., 8-10).

    • If instructed to select a specific number (e.g., pick five), do so regardless of certainty on fewer options.

    • Understanding inclusion and exclusion criteria for specific treatments is crucial.

Identification of Candidates for Reperfusion

Criteria for Thrombolytics

  • Inclusion Criteria (Referencing Lewis, Page 848):

    • Chest pain duration must be less than 12 hours.

    • EKG must indicate STEMI.

Contraindications for tPA Administering

  1. Recent Ischemic Stroke:

    • Absolute contraindication due to risk of bleeding complications.

  2. Recent TURP (Transurethral Resection of the Prostate):

    • Significant risk for bleeding with concurrent tPA administration.

Risks Associated with Reperfusion Therapy

  • Reperfusion Dysrhythmias:

    • Risk of dysrhythmias due to restored blood flow to previously ischemic heart tissue.

    • Analogous to the tingling sensation felt when blood flow returns after compression (hit on foot).

Nursing Interventions for tPA Patients

Prior to Administering tPA

  • Oxygen Administration:

  • Bed Rest:

    • Decreases myocardial oxygen demand.

  • Vital Signs Monitoring:

  • Avoid IV/Punctures:

    • Do any necessary sticks or IV placements prior to commencing tPA administration.

    • Use stool checks for occult blood (FOBT).

Observation for

  • Signs of consciousness changes (indicating potential cerebral bleeding).

  • Monitoring for gastrointestinal bleeding (via FOBT).

    • FOBT Procedure:

    • Smear stool onto test card, apply developer, and check for blue coloration indicating blood.

Patient Care During Admission

Addressing Patient Concerns

  • Importance of empathy given that patients may fear chest pain recurrence or prognosis.

  • Avoid irrelevant responses (example: reading pamphlets) when patients are clearly distressed.

Acute Coronary Syndrome (ACS) Overview

  • Defines as myocardial infarction scenarios including unstable angina and classic symptoms like pressure in the chest (e.g., elephant analogy).

  • Women and diabetics may present atypically with different pain sensations (e.g., shoulder, back, or jaw pain).

Treatment Pathways

  • Thrombolytics vs. PCI (Percutaneous Coronary Intervention).

  • Timing: Ideally, “door to balloon” time is under 90 minutes for PCI effectiveness.

    • If this window passes or the facility lacks a cath lab, thrombolytics may be the only option.

  • CABG (Coronary Artery Bypass Grafting):

    • Major surgery requiring serious considerations (vein grafts, median sternotomy).

Cardiac Catheterization Procedure

Post-Procedure Care

  • Monitoring:

    • Vital signs every 15 minutes initially, assessing for potential clots or complications.

    • Head of bed should be flat or slightly elevated.

    • Perfusion Checks: Capillary refill and pedal pulses must be assessed to ensure proper blood flow post-procedure.

General Management of Heart Failure

Understanding Forward and Backward Effects

  • Poor perfusion (forward failure) results in inadequate blood supply to peripheries.

  • Backward failure leads to congestive symptoms (e.g., pulmonary congestion from left side dysfunction, systemic congestion from right side failure).

Symptoms Associated with Heart Failure

  • Signs of pulmonary congestion (e.g., cough, dyspnea) from left ventricular issues.

  • Signs from right-sided heart failure include JVD and splenomegaly.

Ejection Fraction (EF)

  • Normal Range: 55-70%.

  • Mister Erickson's Condition: EF of 45 indicates poor contractility and potential heart failure.

Closing Notes

  • Discussion about ongoing management and studies regarding heart failure and related illnesses to continue in future sessions.

  • Practical sessions will aid in understanding complex concepts and preparing for exams.
