    Study Notes

    Angina, MI, and Aneurysms

    • Angina Pectoris: Chest pain due to myocardial ischemia (lack of oxygen to heart muscle). Characterized by episodes of chest pain/pressure from insufficient coronary blood flow. Exertion or stress increase oxygen demand, overwhelming the coronary vessels' ability to supply it. Pain can vary from mild to severe, described as tightness, choking, or heaviness; may radiate to the neck, jaw, shoulders, back, or arms (often left). Nitroglycerin is a common treatment.

    • Types of Angina:

      • Stable: Chest discomfort with exertion, short-lived, relieved by rest and nitroglycerin. Often a warning sign of underlying heart issues.
      • Variant (Prinzmetal): Pain at rest, associated with reversible ST-segment elevation on ECG, caused by coronary artery spasms.
      • Intractable/Refractory: Severe, incapacitating chest pain.
      • Silent: ECG shows ischemia but no reported pain. Highly dangerous.
      • Unstable: Increasing frequency/severity, doesn't respond to rest or nitroglycerin; occurs at rest or minimal exertion, marked limitation of activity, and is part of acute coronary syndrome.

    • Acute Coronary Syndrome (ACS): Symptoms indicating unstable angina or acute myocardial infarction.

    • Acute Myocardial Infarction (MI): Heart tissue death from lack of oxygenated blood flow. Ischemia (reduced blood flow) can damage heart tissue. Blood tests (CK, troponin) are used for diagnosis; hypoxia causes increase in heart rate and force of contraction.

    • Beta-Blockers: Actions include reduced heart rate, decreased conduction, lower blood pressure, and reduced myocardial contractility to balance oxygen needs. Not a desired action is increased myocardial oxygen consumption.

    • Medications for Angina and MI:

      • Nitroglycerin (patches, spray): Relieves angina symptoms.
      • Aspirin: Blood thinner.
      • Heparin: Blood thinner.

    • Aneurysms:

      • Damage to the middle layer of a blood vessel.
      • Permanent, localized dilation of an artery.
      • Types: True, false, dissecting, abdominal aortic aneurysm (AAA).

    Risk Factors for MI

    • Modifiable:

      • High cholesterol
      • Smoking
      • High blood pressure
      • Impaired glucose tolerance
      • Obesity
      • Lack of physical activity
      • Stress

    • Non-Modifiable:

      • Age
      • Gender
      • Family history
      • Ethnicity

    Cardiovascular Assessment During MI

    • Blood Pressure: Initially might rise, then fall.
    • Heart Rate: Increases, potentially irregular.
    • Cardiac Rhythm: Irregular.
    • Peripheral Pulses: Weak, thready.
    • Skin Temperature: Cool, clammy.
    • Heart Sounds: S3 gallop (extra heart sound), potentially present.
    • Respiratory Rate: Shortness of breath (dyspnea), decreased respiratory rate.
    • Breath Sounds: Pulmonary edema (fluid in lungs), crackles.

    Percutaneous Coronary Intervention (PCI)

    • A catheter with a balloon and a mesh stent is inserted through an artery (often femoral) to reach and dilate the blocked artery. The stent remains in place to maintain blood flow.

    Angina Pectoris Assessment

    • OPQRST: Used to assess pain. (Onset, Position, Quality, Radiation, Severity, Timing).

    Interventions for Anginal Pain

    • Stop activity, place patient in semi-Fowler's position.
    • Administer medications (e.g., nitroglycerin).
