Study Notes
Acute Coronary Syndrome (ACS)
- ACS refers to a range of symptoms associated with acute myocardial ischemia, which may or may not lead to infarction.
- Types of ACS include:
- ST-Elevation Myocardial Infarction (STEMI)
- Non-ST Elevation Myocardial Infarction (NSTEMI)
- Unstable Angina (UA)
- A rise and/or fall in troponin levels, with at least one value exceeding the 99th percentile, identifies STEMI and NSTEMI.
- UA presents with ischemic symptoms but no elevated biomarkers or ECG changes indicative of ischemia.
Causes of ACS
- Decreased myocardial oxygen supply due to:
- Unstable or ruptured atherosclerotic plaque.
- Coronary vasospasm or atherosclerotic obstruction without clot.
- Inflammation or infection.
- Thrombus leading to artery occlusion.
Symptoms of ACS
- Classic symptoms include:
- Substernal chest discomfort (pressure, heaviness, crushing).
- Shortness of breath (dyspnea).
- Nausea and diaphoresis.
- Dizziness and altered mental status.
- Confusing symptoms can manifest as abdominal pain, dental discomfort, or excessive fatigue.
Angina Pectoris
- Characterized by episodes of chest pain due to insufficient coronary blood flow.
- Occurs in response to increased myocardial oxygen demand (exertion or stress).
- Severity is defined by the impact on daily activities and is not a disease itself but a symptom of underlying heart conditions.
- Can be triggered by other issues like arterial spasm or aortic stenosis.
Risk Factors for Coronary Disease
- Major risk factors:
- Increasing age and gender (men at higher risk).
- Genetic predisposition, particularly in individuals with family histories of heart disease.
- Modifiable risk factors:
- Tobacco use, high blood pressure, high cholesterol, obesity, diabetes, and physical inactivity.
- Contributing factors include stress, alcohol consumption, and dietary choices.
STEMI and NSTEMI
- STEMI signifies a complete blockage of a coronary artery, leading to a heart attack.
- NSTEMI represents a partial blockage and is associated with different implications in treatment and prognosis.
Medical Management
- Use of morphine for pain and anxiety reduction, and to improve oxygenation.
- ACE inhibitors to reduce the effects of angiotensin II, lowering resistance and facilitating blood flow.
- Thrombolytics such as Streptokinase and Alteplase dissolve clots to restore blood flow.
- Oxygen therapy is vital for enhancing oxygen delivery.
Nursing Interventions
- Administer oxygen and medications as prescribed (morphine, nitrates, thrombolytics).
- Help alleviate patient anxiety through information and reassurance.
- Implement rest periods to minimize metabolic demands and provide a proper diet.
- Monitor for complications, especially dysrhythmias, post-myocardial infarction.
Post-Acute Episode Care
- Maintain bed rest initially and gradually introduce mobility exercises.
- Encourage progressive ambulation and evaluate the patient’s condition continuously.
Cardiac Rehabilitation
- Aims to enhance quality of life through physical conditioning and may facilitate a return to previous lifestyle activities, such as sexual activity, when conditions permit.
Nursing Diagnoses for Myocardial Infarction (MI)
- Ineffective cardiopulmonary tissue perfusion related to reduced coronary blood flow.
- Risk of impaired gas exchange due to fluid overload.
- Potential for altered peripheral tissue perfusion from decreased cardiac output.
- Anxiety related to the fear of death and knowledge deficits about post-MI self-care.
